CydandClaude Opus 4.8 6a60b46f8d plasma window: initialize the display area (junk shown until the callsigns) 
The desktop plasma marquee showed heap garbage from boot until the gauge
renderer first drew the callsigns.  Root cause [T0]: PixelMap8(w,h) allocates
its pixel bytes UNCLEARED (GRAPH2D.cpp `new Byte[w*h]`, no memset) and
Video8BitBuffered never clears them either -- only changedLine[] is zeroed.
The real pod never showed it: the serial PlasmaDisplay transfers only CHANGED
lines, so the garbage never left the buffer and the hardware marquee sat at
its power-on blank.  PlasmaWindow::Update however blits the WHOLE buffer
every frame, exposing the junk for the window-up-to-first-draw gap (seconds
on slower rigs).

Fix: PlasmaWindow ctor memsets the pixelBuffer to index 0 (the near-black
background) -- the window comes up blank like the hardware did.  Glass-layer
only; the serial pod path is untouched.  Verified: glass boot shows a clean
marquee from the first visible frame.

Joe DiPrimaandClaude Fable 5 fc71f9c0bb #156 the mission start/end fade RECONSTRUCTED: POVStartEndRenderable was an inert stub (rounds hard-cut) -- the binary's 5-phase fog machine (ctor @00454394, Execute @0045447c; constants byte-read @0x454740-50: flash 0.1s, fades 1.0s, plane floors 0.01/0.05) now runs at the renderer frame head keyed on the local player's SimulationState (3 MissionStarting -> white flash + 1.0s fade-in from white; 4 MissionEnding -> 1.0s fade-to-black, planes closing to the floors, re-arm). Drives the live fog pipeline (currentFogNear/Far + FOGCOLOR, which the frame Clear also samples -- the fade owns sky/void too) and re-reads the STYLE members per frame exactly as the binary re-reads live view fog (mid-fade searchlight swaps track). Armed by the now-real ctor in btl4vid.cpp (house pattern: inert object, module machine). Bench fade_bench.sh: 40s relay-clocked round, both nodes PASS armed + phases 1/2/3/4 in order with the end edge on simState=4. Rider: the [rio] STALL detector now keys on REPLY drought instead of request age (which the 50ms poll refreshed forever -- the detector could never fire; #160 telemetry).

Joe DiPrimaandClaude Fable 5 2938d4918c context-system housekeeping: the 2026-08-11 wave lands in the digests -- router Current-front refreshed + the four audit ledgers listed + the docs/ AI-vs-human split labeled; test-harness gains the standing bench-suite table (kd4/kd8/proj_ttl/gen_edge/xfire + rig notes: clone-the-pilot-page pattern, only map-defined dropzones are valid); multiplayer gains the K/D authority + #45 mirror section with the 4/8-node stress record; combat-damage gains the synchronous-death-transition section (gotcha 25 pointer, tripwire semantics); open-questions replicant-delivery entry gains the 0-of-35-deaths bench datapoint (needs field conditions); the #154 multi-agent audit lanes preserved from session temp as docs/GEN_WARNING_AUDIT_20260811.md (with the no-speech retraction lens noted). checkctx: CLEAN.

Joe DiPrimaandClaude Fable 5 1b6d247e51 #162 4-node retest CAUGHT + FIXED a same-frame double-credit: two lethal deliveries of one salvo (direct + splash, 2ms apart, no sim tick between) each read destroyedAtEntry=0 -- the entry latch samples movementMode 2||9 but our death transition (mode 9 write) ran NEXT TICK in UpdateDeathState, while the binary flips mode SYNCHRONOUSLY inside the same damage pass (its tail gate part_012.c:14761 reads 9||10 already set). Result: duplicate kill credit to the shooter (bench receipts: kills 1->2 in 2ms, awards 525.00/516.67) and a duplicate VehicleDead whose death cycle the receiver dedup swallowed -- but the kill report had already escaped. Invisible to every 2-node bench (direct kills deliver one lethal hit; splash+direct overlap needs crowds) -- the 8-player field 'kills way off' shape. Fix: the death tail now runs the once-per-death transition inline (mode 9 + type-6 + effects) before returning, exactly the binary's sequence; the next lethal message latches on both destroyedAtEntry and deathBlastArmed. The wrong 'synchronous' claim in the old comment corrected. Benches: kd4_bench (receipt-derived per-player invariants + bystander mirror convergence + no-mirror-exceeds-authority + inst=R audit) PASS 9/9/9/9 SWALLOWED=0; kd8_stress staged (8-node all-vs-all melee).

Joe DiPrimaandClaude Fable 5 7fa6dc536c #135 FIXED, two defects: (1) the generator lamp special was mis-reconstructed -- the binary @004cc27c is table_0051d070[generatorNumber] (bytes {0x29,0x1A..0x1D}, 1-based A..D, same shape as the condenser special), not an aux-screen placement probe generators never fill; a leaking generator now flashes its own lamp (benched: '[lamp] 0x1a <- 0x37 (FLASHING)' on a GeneratorA leak; was the field-logged 'NO LAMP RESOLVED'). (2) the eternal loop-button flash: Lamp::SetAlertState/SetState drop their panel notify when the edge lands off-page or in the one-frame mask race of a page transition, and the panel value latches the last-asserted flash forever -- Oracle's 'Loop 6 NEVER stopped' with Condenser6 SET/CLEARED balanced 3/3 in his log (the alarm manager was right; the lamp was stale). The skipped notify is now remembered and delivered at the lamp's next in-mode frame. KB: decomp-reference gains the 0x51d070 table + the stale-flash gotcha.

Joe DiPrimaandClaude Fable 5 14c62f184d #166 mechanism pinned + two input-layer fixes: Oracle's LRM jam = the ammo bin PARKED at Ejecting(3) with rounds aboard (his log: 'NoAmmo (gate2): rounds=18 binState=3', twice; eject tap cleared it exactly as the handler predicts). The MFD/HUD 'desync' is honest: the full green circle is the RECHARGE dial (untouched by the gate2 pin) and the btejam lamp keys only on weaponAlarm 5 (binary @004c9a38) -- state-7 pins show neither, authentically. The parking producer needs an unpaired eject PRESS, which pod hardware cannot make but our glass mouse layer could: (1) WM_CAPTURECHANGED now releases a held panel button when capture is stolen (Steam overlay/popups ate the WM_LBUTTONUP), (2) a new press releases any still-held previous button instead of orphaning it. Forensics: every EJECT message now logs data/bin/ejectState/binState/rounds always-on (ejects are rare) -- Friday names the producer if it recurs. Smoke: BT_EJECTTEST replays the full press/hold/dump receipt chain incl. the authentic mid-eject gate2 pin.

Joe DiPrimaandClaude Fable 5 18fba98298 #165 does not reproduce -- the destroyed-weapon fire gate HOLDS on the exact field path: bench (xfire_bench.sh) kills ERPPC_1+ERSLaser_1 via the cascade's own ForceCriticalFailure writer under held autofire -- ERSLaser_1 9 FIRED pre-kill, 0 post, 4213 refusals (destroyed=1), surviving ERMLaser fires on. Rajel's field read explained: the refusal tail recomputes output voltage every tick (binary-authentic), so a destroyed weapon's recharge dial keeps CYCLING under its X while the surviving torso lasers put the beams peers saw. Rider: the [emitter] FIRED receipt now NAMES its weapon under BT_DMG_LOG (the #110 nit) so the next field session can settle it by name.

Joe DiPrimaandClaude Fable 5 c8373f2407 #169 lobby room layout: LEAVE button was half-clipped because 560x360 was the OUTER window size (the caption bar ate the bottom ~47px of a client that needed 336+), and rosters past 6 members drew through the fixed LAUNCH frame at y=250 (rows flow to 268 at 8 players). Buttons now sit below the full 8-slot roster (LAUNCH 280-326, LEAVE 336-366) and the window is sized by CLIENT rect via AdjustWindowRect (560x382). Geometry-proven; visual verify = next lobby + Friday's 8-player night.

Joe DiPrimaandClaude Fable 5 8d2f48225b #154 correct the record: the warnings ARE VOICE -- Warnings01/AllWarning zones are Yip's recorded words, phrase-sequenced by the AudioControlSequences (our own #119 commit 42b0691 said so); the generator sequence z4/z0/z3 is the spoken 'Warning, generator out'. The same-day 'BT 4.10 shipped no speech / era memory is Firestorm' claim is retracted -- it rested on preset names and ignored repo history; with the voice real, the era memory of hearing it at the TRIP may be genuine (possibly a later floor revision fixing the same authored bit our deviation flips). The fix itself stands and is strengthened. KB entry rewritten + process lesson recorded (grep git log before asserting absence).

Joe DiPrimaandClaude Fable 5 08fc87ec6e #154 settled: the generator-out warning was authored on the WRONG EDGE in the shipped 1995 content -- BTL4.RES keys it (trigState=4, inverse=1, Start) = fire on LEAVING GeneratorOut, so a thermal trip was SILENT and the klaxon played at recovery/respawn (live-benched both ways; decode triple-verified: T0 read order, binary @0043e7d4/@0043eb40 semantics, independent byte parse; 144-row census = the game's ONLY inverse-Start fault trigger). DELIBERATE DEVIATION (user-approved, the port's only content override): AudioStateTrigger ctor flips it to enter-4 at stream time -- warning at the TRIP, silent at recovery + the respawn 4->0 edge; BT_GEN_WARN_SHIPPED=1 restores shipped. Threshold audit closes AUTHENTIC: recovery at heatAlarm NormalHeat = T<=1000 vs trip at 2000 = exactly the manual p23 half-cooled rule, and the heat bar's red fill maps to it to the tick. Era-witness reconciliation: BT 4.10 shipped NO speech samples (full AUDIO1/2.RES census) -- the remembered voice at trip is Firestorm's. Rig: BT_GEN_HEAT injection + BT_AUDIO_EDGE receipts, gen_edge_bench.sh PASS (4 fixups, trip FIRED, recovery 0). KB: decomp-reference generator section + no-speech note; manual p23 also answered #133 (X = crit-destroyed).

Joe DiPrimaandClaude Fable 5 e2ab17665d #168 settled from the binary: projectiles are TIME-capped, never range-capped -- plain shell 5.0s (@4bddec), missile burnTime+10s + y<-1 kill-plane (@4bef78), WeaponRange is fire-control only (FireWeapon @4bcc60 has no range gate), so AFC50 hits at 2000+u are authentic. Two port defects killed: the invented len*1.3+60 flight cap (replaced by the authentic clocks) and the stale-point auto-hit (unguided contact tested the fire-time pick, so a locked AC could not miss a moving target -- the pool now tracks the live target). KB: decomp-reference gains the flight/expiry section, CLASSMAP's swapped authoritative/ghost Performance labels corrected (ReplicantInstance=4 [T0]), missile.cpp's misdecoded @4bf594 constant pool re-annotated, Missile proximity fuse 4.0u recorded. Bench: proj_ttl_bench.sh (probe fizzles 5.012/12.012 vs caps 5.0/12.0; 86 field launches, 0 early, 0 phantoms). Rides along: the #163 BTSteamNet_ShutdownAll header decl that missed d3f4b9a.

Joe DiPrimaandClaude Fable 5 dfefdfa1d0 #128 terrain-ram instant coolant leak FIXED at the eligibility tag: GUID 0x50e590 is the AGGREGATE BANK's node (0xBBE), not the HeatSink base family -- the family-wide reading made every coolant-bearing subsystem (myomers, condensers, reservoirs...) rattle-eligible, so one over-floor ram sub-hit sprang an instant leak (field: Michael's 3 rams all 'Myomers condition 2 SET' -- a subsystem 1995 can never select). Authentic set {HeatSinkBank .30, Gyroscope .35, Torso .25}; scrapes remain free via the byte-anchored 0.5-pt floor (the 30k-lines/night [crashdmg] spam now sampled).

Joe DiPrimaandClaude Opus 5 46ff8dd262 #150 double kill FIXED (two binary-cited gates) + #151 measured AUTHENTIC to the point 
#150 -- one kill credited twice (Rajel on Oracle, Oracle on Conn Man).
CAUGHT: one death -> two type-2 arms 1ms apart (awards 501.96/505.88 -- the
tally GREW between them), victim inst=R.  Mechanism: this port deliberately
applies damage on replicants for local visual response; the report tail ran
there too, and a replicant's movement mode cannot flip to wreck until the
victim's death record round-trips -- so each round of a killing VOLLEY inside
that window re-posted the kill.  Why missiles, why intermittent.

The binary forbids the whole situation: its handler OPENS with the assertion
  if ((flags & 0xc) == 4) Fail("Replicant Mech recieving takedamage",
                               MECH.CPP, 0x3da)          [part_012.c:14613]
-- TakeDamage on a replicant was a BUG in 1995; the tail only ever ran on the
victim's master.  Fix: (1) gate the REPORT TAIL master-only (local damage
application stays); (2) adopt the binary's once-latch -- the 0->1 edge of
IsMechDestroyed() across the handler call (local_14), replacing the
deathBlastArmed form for the report gate.

VERIFIED (scratchpad/night14/scorepair.sh): 3 victim deaths, 5 shooter
respawns -> exactly one type-2 per credited kill, kills 0->1->2, zero doubles
(was: kills 0->2 on one death).

#151 -- panic eject "-499 instead of 0" is AUTHENTIC 1995 SCORING, decoded
from EjectPilot @0049f854: the punch-out dispatches a SELF TakeDamage of
  damageAmount = role->killBonus (+0x1c, 500 in dfltrole), type Explosive,
  senderMechID = SELF, player->suppressConsole = 1, graphicAlarm -> 10
which flows through the report tail as a SUICIDE kill: award = -CalcKillScore
(your own death), plus the type-1 death cost.  1000 - ~999 - 500 = -499:
the binary predicts Oracle's exact number.  Our port already used
role->killBonus for the blast (mech.cpp:652) -- faithful end to end; bench
shows each eject charged exactly once (-900/-1050 across three ejects).
Panic eject = scored as suicide.  Whether that is fun is a design question;
it is not a porting defect.

CydandClaude Opus 4.8 3aeb2dbbe8 glass panels: add the PlaneChecksum header decl (completes c9e25e5) 
The dirty-skip commit staged the header via a lowercase path (l4vb16.h) while git
tracks it as L4VB16.h on this case-insensitive FS, so the PlaneChecksum declaration
was left out -- c9e25e5 as committed would not build from clean (L4VB16.cpp defines
SVGA16::PlaneChecksum, L4GLASSWIN.cpp calls it, but the header never declared it).
This adds the one-line decl.  HEAD now builds standalone.

Follow-on to the HALFTONE->COLORONCOLOR fix.  BTGlassPanels_Tick repainted all 7

token and the pump re-blits ONLY the windows whose token differs:

  token = FNV-1a checksum of the shared gauge pixelBuffer masked to the bits this

Folding the flash BRIGHTNESS (not the raw lamp state) into the token means a flashing
lamp repaints exactly when it toggles; a static panel or an idle cockpit skips its
expand + StretchDIBits entirely.  The masked checksum reads the RENDERED RESULT of the
gauges' values, so it catches everything -- discrete value gauges, the continuous
radar sweep, any imagery -- with no gauge->port->window plumbing and no risk of a
frozen display (full pass, no stride; collision-free in practice).

Measured (dev box, solo mission, BT_GLASS_DIRTY): ~31 pumps/2s -> 4-15 window-repaints
vs 217-224 always-on (~15-40x fewer); avg frame work 3.3 -> 0.93ms.  BT_GLASS_DIRTY=1
logs the repaint tally.

CydandClaude Opus 4.8 f3d27f51c2 glass panels: drop HALFTONE stretch (the per-display-mode perf sink) 
Playtester (Dave, SCREECH-PC, 4K) reported ~20 fps in the exploded per-display
glass panels vs ~130 fps in the cockpit surround -- same scene, same machine
(solo_20260809.log; maxDraw 57-92ms in panels vs 6-31ms surround).

Root cause: BlitSurface used SetStretchBltMode(HALFTONE) -- GDI's slowest,
per-output-pixel resample filter -- and BTGlassPanels_Tick repaints all 7 glass
windows SYNCHRONOUSLY on the main render thread every ~16 Hz.  7x HALFTONE
StretchDIBits of a 640x480 surface per pump stalls the frame.

Default to COLORONCOLOR (nearest); BT_GLASS_SMOOTH=1 restores HALFTONE.  The
MFDs are low-res pixel content, so nearest reads crisp -- arguably closer to the
pod CRT than the blur.  A/B on the dev box (fast, understates Dave's gain):
avg work 3.3->1.4ms, maxDraw stall 12-27->7ms, ~2.2x more frames per window.

Joe DiPrimaandClaude Opus 5 2ed51cb1f3 #149: [glassperf] VERIFIED in the 2-node render harness (correcting 9e78d1c's premature claim) 
9e78d1c said 'smoke-tested: lines live' -- that run never entered the render
loop and printed nothing.  This run did: 54 [glassperf] lines, e.g.

  ticks=16 tickMs=256.9 | Heat MFD 24.8 | Engineering 20.6 | Comm 18.7 |
  LeftW 20.6 | RightW 22.8 | Secondary/Radar 67.9 | ...

First finding, already: the synchronous panel sweep costs ~257ms/second even
on the DEV box (25% tax, hidden in headroom), and Secondary/Radar -- the
ROTATED portrait blit -- is the most expensive window.  Oracle's machine
paying 4-8x that through his driver is now a quantified hypothesis, not a
guess.  Optimization targets regardless of his verdict: dirty-gated repaints,
non-HALFTONE unscaled blits, cheaper rotation.

Joe DiPrimaandClaude Opus 5 9e78d1cc23 #149: [glassperf] -- per-window glass paint timing, one line per second, default on 
Oracle confirmed the separate-window glass mode WAS fast and tanked ~2 builds
back, so the regression is real and expresses only on his machine.  This names
the cost from inside his own session log:

  [glassperf] ticks=N tickMs=T | <window> n=paints ms=cost | ...

tickMs is the synchronous UpdateWindow sweep measured INSIDE the render frame
(L4VIDEO calls the tick), so on a machine where GDI serialises against D3D
present it IS the per-frame tax, and the per-window split names the panel.
Each WM_PAINT is QPC-timed at the dispatch chokepoint (the HALFTONE
StretchDIBits whose cost is driver-dependent).  Default ON like [segperf];
BT_PERF_LOG=0 opts out.  Smoke-tested: lines live in a 60s panel run.

Joe DiPrimaandClaude Opus 5 2b6b0276fd #152: the real hole -- glass/RIO rigs had NO torso-centre control; wire pod button 0x42 
The reported "torso no longer recentres on its own" decomposed into two parts:
the auto-recentre in Mid/Adv was never authentic (it was the stuck-centerCommand
bug acting as a phantom feature since ~674 -- analysis on the ticket, awaiting
Oracle's 1995-memory verdict), but underneath it sat a REAL defect: with the
phantom gone, a glass/RIO player had no way to recentre the torso at all.

WHY.  The only centerCommand writer lived inside the desktop key-bridge block,
which is OFF whenever a RIO/PadRIO is present -- glass and the pod both.  The
pod's dedicated CENTER button (0x42, "the shipped .RES name", UP arrow via
bindings.txt) reached nothing: benched two scripted 0x42 holds on the RIO path,
ctrCmd=0 throughout, twist parked forever.  (Keyboard X/NumPad5 recentred only
as a side effect of ALL-STOP -- you could not recentre without stopping.)

FIX, two pieces, both existing patterns:
  * L4PADRIO::EmitButton -- the documented single chokepoint every button
    source funnels through -- publishes the 0x42 HOLD state
    (gBTTorsoCenterHeld), exactly the 0x3F ReverseThrust precedent.
  * mechmppr gains ONE unified centerCommand writer, deliberately OUTSIDE the
    key-bridge gate (the same placement lesson as the mode-cycle hook):
    hold = torsoCenter(@0x154 databound) OR gBTTorsoCenterHeld(0x42) OR the
    one-frame X pulse; asserts while held, clears on release.  Single writer
    == the sources can never stomp each other's clear.

BENCHED (scratchpad/night14/center42.sh, RIO path, bridge off):
  before: ctrCmd=0 in all samples across two 0x42 holds; twist parked at 1.478
  after:  hold -> ctrCmd=1 recen=1, twist slews 2.22->0.44 at the authored
          0.87 rad/s; twist input DURING the hold cancels sim-side (authentic);
          release clears; no button -> aim holds (authentic Std/Vet).

Joe DiPrimaandClaude Opus 5 aa250c4e22 #149: [segperf] telemetry DEFAULT ON for every player (BT_PERF_LOG=0 opts out) 
Operator call: an opt-in flag on the one machine we most need data from is
the silent-diagnostic mistake this project's doctrine exists to prevent.
Every session log now carries [segperf] beside every [rstat] window, so the
next playtest gives the 817->857 stall hunt cross-machine baselines for free
-- Oracle's stalling rig and Sauron's clean one, same night, same build.
Cost: ~2 QPC reads per segment query, microseconds per second.

Joe DiPrimaandClaude Opus 5 a77c5a1407 #149: measure the filed suspect -- the #141 segment sweep is EXONERATED; ship [segperf] telemetry 
A/B on identical 2-node beam-heavy runs (scratchpad/night14/segperf.sh),
BT_BEAM_SEGFRESH=1 (swept behaviour) vs =0 (pre-sweep compose at the beam
site, the only per-frame swept call):

                    fresh(swept)   legacy(pre-sweep)
  rstat blocks>50ms       0              0
  maxDraw worst         730ms          646ms      (mission-load spike, BOTH)
  segperf dirty-passes   38/s            4/s      <- the sweep DOES multiply
  segperf accessor ms   0.97/s          0.57/s    <- ...by 0.4 ms/s.  Noise.

So the invalidation-storm hypothesis I filed on #149 is wrong by three orders
of magnitude, and Oracle's sustained 50-104ms stall window does NOT reproduce
on this rig at all.  Refusing to guess a third time: the build now carries the
telemetry to answer it on the machine that actually regresses --

  [segperf] calls= dirty= ms=   printed beside every [rstat] window under
  BT_PERF_LOG (JMOVER counters; two integer increments when unset), and
  BT_BEAM_SEGFRESH=0 remains as a one-env A/B for the beam site.

Default stays FRESH (the swept accessor): its measured cost is trivial and it
is the correctness-cautious side while the peer-beam-staleness question is
unmeasured.

Next for #149: Oracle runs one session with BT_PERF_LOG=1.  If [segperf] ms is
large inside his stalled windows, segment work is implicated on HIS
configuration and BT_BEAM_SEGFRESH=0 gives the immediate A/B; if it is small
(as here), the stall is elsewhere in the 817->857 delta and we hunt with his
numbers instead of my theories.

Joe DiPrimaandClaude Opus 5 0d6ed40db9 #137 FIXED: restore the binary Reset's +0x58c re-seed -- the respawn freeze was a 
teleport-poisoned finite difference, not heat, not the reset, not velocity

The one-line fix is the binary's own SECOND Reset instruction, dropped in
transcription:  FUN_00408440(mech+0x58c, param_2)  ==
    accelPrevPos = origin.linearPosition;
+0x58c is the previous-position memory of the AccelerationLastFrame ring feed
(+0x81c/0x824/0x828/0x82c).  The port reconstructed the ring faithfully (ctor
part_012.c:9836, derivative :15169) but Reset never re-seeded its cache, so the
first post-respawn sample computed |newPos - prevPos|/dt = TELEPORT DISTANCE/dt
(~1e5) into the velocity ring; the ring-mean derivative spiked
AccelerationLastFrame (pure forward, with an opposite-sign echo ~15 frames later
as the sample rotated out of the 15-ring); and the myomer integrator @004b8d18
turned it into a one-tick pendingHeat deposit of ~3e9:
    termAccel = (1-accEff) * |v| * |a| * m * dt
      = 0.2 * 40 * 1.04e5 * 75000 * 0.044  =  2.75e9
snapping the freshly-reset myomers from T=77 to T~9000 against failT=2000 ->
speedEffect 0 -> speedDemand *= 0 -> "respawned unable to move until it cools".

WHY ~8% IN THE FIELD: the deposit needs |v| in the same 1-2 frames, so only
pilots whose throttle was still forward at the respawn -- physical lever /
HOTAS, exactly who reported it -- had gait-republished speed in the spike
frames.  Idle-throttle respawns deposit ~nothing.  (And frozen-subset-of-
died-hot: died hot == was running hard == lever still forward.)

MEASURED, same abusive bench (0.95 throttle + continuous autofire):
    before: deposits up to 3.35e9, every one 3-4 lines after a Mech::Reset;
            4-6 of 7 respawns frozen; post-reset myomers T 7700-12100
    after:  deposits >1e7: ZERO across 7 respawns; frozen: ZERO;
            post-reset myomers T 77-178 (vs degradeT=1000)

THEORIES KILLED ON THE WAY, each by operand data, in order:
  * stale pendingHeat carryover (bounded to 1 frame, +1.2K -- gates agent)
  * slow accumulation during the death window (consumers tick the wreck)
  * conduction from a hot neighbour (roster-wide snapshot: ALL partners 77;
    flow trap: zero e6 flows into the myomers, ever)
  * drag/impulse writers (both trapped: never fired)
  * my own earlier "velocity-driven, players accelerate to top speed" close of
    the ticket -- arithmetically impossible (input ceiling ~6.5e5/frame ~=
    60 deg/s; the observed snap was 1,100-21,000 deg/s) and corrected in
    context/subsystems.md, which carried the wrong paragraph.
  * the localAcceleration zero-fill (+0x1dc) restored along the way is KEPT --
    the binary does it -- but it was NOT the cause; the snapshot is rebuilt
    from the position difference one frame later.

Probes kept (all BT_HEAT_LOG-gated): roster-wide [myofreeze] at-death/at-reset/
post-reset (T + heatEnergy + pendingHeat per subsystem), the [heatflow]
conduction trap with full operands, the [myodep] deposit trap with mech
identity + acceleration components.  Engine MOVER.cpp traps reverted -- they
proved their negative (drag/impulse innocent) and do not belong in engine
source.

Gotcha #30 records the class: when the binary's Reset writes a cell you don't
recognize, that write IS the spec -- transcribe the whole zero/seed list; any
prev-value cell backing a finite difference must be re-seeded at every
teleport; and derived state (T) sampled at the reset proves nothing about the
backing producers.

The operator called the shape of this two days ago: "maybe the math gets screwy
in respawning while some systems are ticking while values are being reset."
That is precisely what it was.

Joe DiPrimaandClaude Opus 5 df1b4651b3 #137 CALIBRATION SETTLED: the myomer heat math is faithful -- constants read byte-exact 
Read the integrator's constants from .rdata rather than inferring them.  Row
` 4b8ee0  5dc30000 0000003f 00000000 0000803f` gives:

    _DAT_004b8ee4 = 0.5f   the kinetic half  (work = mass * |v|^2 * 0.5)
    _DAT_004b8ee8 = 0.0f   the Abs() idiom zero
    _DAT_004b8eec = 1.0f   the (1 - efficiency) complements + gear clamp floor

All three are exactly what the port computes, and the logged terms reproduce
from the authored tuning to the digit:

    work        = 75000 * 54^2 * 0.5                       = 109.3e6
    complement  = 1 - VelocityEfficiency(0.995)            = 0.005
    termKinetic = 109.3e6 * 0.005 * (dt*28 = 0.728)        = 398e3  (logged 399003)

THE ONE DEVIATION IS DELIBERATE AND IS THE FAITHFUL CHOICE.  The binary applies
NO time_slice to the kinetic term (`fVar5 * fVar1`) while climb and accel both
carry param_2 -- a per-frame energy add at the pod's FIXED ~28 Hz.  The port's
`work * (time_slice * 28)` is identical at 28 Hz (dt*28 = 1.0) and holds the same
heat-per-SECOND at any frame rate.  Transcribing it literally would add the full
term once per frame, so at Oracle's measured 170 fps it would inject ~6x the heat
the pod ever did.  Preserving behaviour beats preserving the artifact of a fixed
timestep.  BT_MYO_HZ still brackets the reference rate.

SO #137 IS NOT A CALIBRATION DEFECT.  Heat is QUADRATIC in speed, so v~50 on open
ground after a respawn is ~9x the input of v~10-18 in a fight -- which is why the
overshoot correlates with respawns without being caused by them.  It is also
self-limiting: effectiveness reaches 0, the mech stops, speed falls, it cools.
That is the authentic governor.  Whether the cliff is too punishing for players
is a DESIGN call for the operator, not a fidelity bug.

Recorded in context/subsystems.md so the next reader does not re-litigate the
dt-normalisation as a bug.

Joe DiPrimaandClaude Opus 5 6a122f6cdf #137: the post-respawn heat spike is VELOCITY-driven, not reset corruption 
Operator hypothesis tested: does something tick mid-reset and compute across
half-reset values (the teleport discontinuity) and inject a heat slug?

NOT SUPPORTED, measured.  [myoheat] terms straddling a respawn:

    BEFORE (-334)  v=10.7  kinetic= 21941
    BEFORE (-116)  v=18.8  kinetic= 59560
    AFTER  (  +17) v= 6.1  kinetic=  3517   <- SMALL at the discontinuity
    AFTER  ( +129) v=46.7  kinetic=297349
    AFTER  ( +337) v=54.1  kinetic=399003

The sample immediately after the reset is small.  Nothing computes across the
teleport; there is no injected slug.

WHAT IT ACTUALLY IS.  work = mass * v^2 * 0.5, so heat is quadratic in speed.
After a respawn the mech reaches v~50 against v~10-18 while fighting before it
died -- roughly 9x the heat input -- because it comes back on open ground with
nothing to fight and accelerates to top speed.  That is why the earlier
correlation looked like causation: temperature is highest just after a reset and
decays with distance from it, but the driver is SPEED, not the reset.

Reconciles both benches: 0.95-throttle runs overshoot, 0.50-throttle runs never
approach failT, and the operator's point that ordinary gameplay feels fine holds
-- at combat speeds the model behaves.  It only runs away at sustained top speed.

Term arithmetic checks out against the authored tuning:
    work = 75000 * 54^2 * 0.5              = 109.3e6
    workComplement = 1 - VelocityEfficiency(0.995) = 0.005
    termKinetic = 109.3e6 * 0.005 * (dt*28 = 0.728) = 398e3   (logged 399003)
so the port is computing what it intends to.  The open question is whether the
INTENT is right -- i.e. whether (1 - 0.995) against the FULL kinetic energy is
the authentic scaling, or whether the binary's dt-less per-frame add at the
pod's fixed ~28 Hz means something different from our rate-normalised form at
100-170 fps.  That is now a calibration question with a specific target, not a
hunt.

Joe DiPrimaandClaude Opus 5 8c612e4e18 #137 SOLVED (mechanism): not a respawn bug -- the myomer heat RATE under load is 
Controlled A/B on the same bench, only the load differs:

  0.95 throttle + continuous missile autofire : 4 respawns, 17 frozen samples,
                                                T climbs 77 -> ~11,600
  0.50 throttle, no weapons                   : 2 respawns, ZERO post-reset
                                                freezes; T stays ~77

So the respawn is exonerated on measurement, not on argument:
  * the reset works -- T == startingTemperature at every reset, both runs;
  * the stale Myomers::speedEffect (@0x31C, which no RTIS writes) is real but
    self-heals on the next tick (T=77.13 -> speedEffect=1);
  * with ordinary load the myomers never approach failT=2000 after a respawn.

WHAT PLAYERS ARE ACTUALLY SEEING.  Overheat while running hard -> myomers pass
failT=2000 -> derating curve @004b8ac0 returns 0.0 -> chain MAX 0 ->
speedDemand *= 0 -> bogged down -> die (often BECAUSE bogged down).  Respawn
correctly resets to 77.  Resume high throttle + firing and it climbs back over
the cliff within seconds, which reads as "respawned with the heat bar maxed".
That is why it looks like a reset bug and why it is intermittent (~8% of
respawns in the field): it tracks how hard you were driving, not the respawn.

THE REMAINING DEFECT is the CLIMB RATE, not the reset.  Blowing ~6x past a
cliff the design treats as coolant-managed (degradeT=1000 governor onset,
failT=2000) is not a lever a player can work with.  Suspect under review: the
kinetic term.  The binary (@004b8d18) applies NO time_slice to it --
`fVar5 * fVar1` -- while the climb and accel terms both carry param_2, i.e. it
is a per-frame energy add at the pod's fixed ~28 Hz.  Our port rate-normalises
it (`work * (time_slice * 28)`), which agrees per-second at any frame rate, so
that is NOT yet a proven discrepancy -- it needs a term-by-term dump against
the authored tuning (VelocityEfficiency 0.995, AccelerationEfficiency 0.8,
thermalMass 2.5e5, myomers linked Condenser5 = Oracle's "loop 5").

Joe DiPrimaandClaude Opus 5 5556329807 #137: REPRODUCE the myomer freeze -- reset is innocent, the myomers RUN AWAY after it 
First reproduction of #137 in a bench.  The reset path is exonerated and the
real defect is located, though not yet explained.

DECOMP RE-READ (what the reset actually does):
  Mech::Reset @0049fb74 walks the roster from index 2 calling vtable +0x28
    (slot 10 = ResetToInitialState), then @0049f788.
  Myomers::RTIS @004b8aa4 -> PoweredSubsystem::RTIS @004b0e6c -> ALWAYS
    HeatSink::RTIS @004ad760, whose first act is
        param_1[0x45] = param_1[0x4f]     // currentTemperature = startingTemperature
    (byte 0x114 = 0x13C).  Our port matches AND additionally resets heatEnergy,
    which it must, since HeatSinkSimulation derives
        currentTemperature = heatEnergy / thermalMass.
  The freeze itself is the derating curve @004b8ac0:
        temp >= degradation(@0x118) -> falls off
        temp >= FAILURE(@0x11C)     -> 0.0  -> chain MAX 0 -> speedDemand *= 0.
  Nothing in the reset chain touches Myomers::speedEffect (@0x31C).

MEASURED (scratchpad/night14/myofreeze.sh -- hot mech, repeated self-kill):

    at-reset   Myomers T=77      deg=1000 fail=2000  speedEffect=0   <- stale
    post-reset Myomers T=77.14                        speedEffect=1   <- 1 frame
    post-reset Myomers T=9297.8  fail=2000            speedEffect=0
    post-reset Myomers T=11620.4 fail=2000            speedEffect=0

So, in order:
  * THE RESET WORKS.  T is exactly startingTemperature at the reset.  My
    original bench was right about that much; it just stopped looking there.
  * THE STALE speedEffect IS REAL BUT HARMLESS -- it survives the reset (no
    RTIS writes it) yet self-heals on the very next tick.  Not the bug.
  * THE MYOMERS THEN RUN AWAY: 77 -> ~11,600 against a FAILURE point of 2,000,
    nearly 6x over, in seconds.  That is not heat earned by running; that is a
    runaway, and it is what pins speedDemand at 0 until it cools -- exactly
    Oracle's "maxed heat bar ... unable to move until it cools off".
  * Rate: 7 of 105 census samples over the failure temp (~6.7%), against the
    field's 5-of-61 respawns (~8%).  Same order, so the bench is reproducing
    the field condition and not a bench artifact.
  * The myomers link to Condenser5 (mass=250000 k=190000) -- literally Oracle's
    "loop 5 and generator D heating up as all the excess heat goes into the loop".

NOT YET ESTABLISHED, and the reason this is a checkpoint and not a fix: whether
the runaway is CAUSED by the respawn or is a heat-model calibration problem that
merely CORRELATES with it (you die when you overheat, so respawns cluster around
hot periods).  The bench drives at 95% throttle with continuous missile autofire,
which is abusive, and the [heat-t] census has no pre-first-reset samples to
compare against.  Next step is to instrument the heat INPUT and diff a
respawn-adjacent window against a steady-running window.

Probe added: [myofreeze] prints T / degradation / FAILURE / speedEffect per
myomers plus the chain MAX the mover multiplies by, AT the reset and for ~4 s
after (armed by Mech::Reset, sampled where the multiplier is formed).  The
post-reset window is what nothing was watching -- sampling only at the reset is
what made this look innocent and got the ticket wrongly closed.

Joe DiPrimaandClaude Opus 5 92783b9935 night14: tracker housekeeping for the 4.11.857 playtest 
Closed 5 confirmed-fixed (#52 #108 #140 #141 #142), commented 3 (#135 #146
#147), REOPENED #137, filed #149-#158.

#137 reopened because I closed it wrongly.  Field scan of all four logs: 5 of
61 respawns froze (throttle up, speedDemand pinned at 0) across THREE machines
-- ~8%, which is why a bench that reset cleanly every time never saw it.  The
myomers come up Overheating in the same breath as Mech::Reset, before any
running could earn the heat.  Oracle's 'unable to move' was the detail that
disproved my 'it earns the heat by respawning under throttle' explanation.

Joe DiPrimaandClaude Opus 5 0961a0b3f3 Revert the key G action ModeCycle default -- F7 already does it, on both keymaps 
c1a87b6 added G on the premise that a keyboard-only player could not reach the
control mode.  That premise was WRONG, caught by the operator: I checked only
for `action ModeCycle` verbs and missed the CONSOLE BUTTON route.

    content/bindings.txt:147   key F7 button 0x18
    content/CONTROLS.MAP:136   key F7 button 0x18

0x18 IS CycleControlMode (context/pod-hardware.md:69), and it is wired:
MESSAGE_ENTRY(MechControlsMapper, CycleControlMode) ->
CycleControlModeMessageHandler -> CycleControlModeNow -- the same body the
gamepad Start and the pod console button drive.  So F7 has always cycled the
mode from the keyboard, on BOTH keymaps.  Every console button really is mapped.

Worse than redundant: CONTROLS.MAP:172 already binds `key G action Flush`, so
shipping G=ModeCycle in the glass default board would have made G mean different
things on the pod and on glass -- two populations with two sets of muscle memory,
which is precisely what the bindings-board migration exists to prevent.

Reverted from the shipped default template and from the local bindings.txt.
The torso-twist verification stands: the operator cycled modes and confirmed the
fix live; only the key used to do it was needlessly new.

Joe DiPrimaandClaude Opus 5 06d3b93507 pod: fix the podkit INFINITE LOOP, version-control podkit.ps1, and write the remote runbook 
Deploying 4.11.854 to the cart hit a wall that was entirely self-inflicted and
entirely undocumented.  Both are fixed here.

THE BUG.  podkit.ps1 (which pushes the frozen rig config into a fresh install)
had, at line 30:

    while ($keep.Count -gt 0 -and $keep[-1].Trim() -eq '') { $keep = $keep[0..($keep.Count-2)] }

Once $keep trims to a SINGLE blank line, $keep.Count-2 is -1, and PowerShell's
$keep[0..-1] returns TWO elements (index 0 and index -1) instead of shrinking --
so the array GROWS and the loop never ends, RSS climbing past 60 MB.

It fires whenever everything outside environ.ini's marker block is blank, i.e.
any environ.ini that was ALREADY kitted -- which is exactly what you get when you
carry config forward from the previous install, the normal upgrade path.  So this
would have bitten every future deploy, not just this one.

Signature: a BLANK cmd console on the cab, BT411Run stuck "Running", no btl4.exe,
no podrun.log.  And it CASCADES: each hung run holds environ.ini so every later
attempt blocks behind it -- while over SSH your client times out and the REMOTE
powershell keeps running, so "it returned instantly and did nothing" actually
means "it is still hung".  Six stuck processes had piled up before I spotted it.

Fixed to `-gt 1`, patched on the pod (podkit.ps1.bak is the original), and the
script is now IN THE REPO (tools/podkit.ps1) with the trap explained inline --
previously it existed only on the cab, so a restore would silently bring the bug
back.  Pod and repo copies are byte-identical.

THE RUNBOOK (context/pod-hardware.md).  Written because I improvised instead of
reading the one paragraph that already existed, on a live stream.  Now covers:
  * ssh bt411-pod -- and WHY it looked like auth was never set up: the key has
    existed since 2026-08-06, but ssh will not OFFER it without a ~/.ssh/config
    entry, so you get "Permission denied (publickey,password,...)".  Also that
    the Tailscale NODE KeyExpiry is not an SSH credential and Tailscale SSH is
    not enabled on the pod.
  * bare taskkill/setx return "The system cannot find the path specified" over
    this SSH+cmd session -- call System32 tools by ABSOLUTE path.
  * the deploy sequence, identical to a tester's: mkdist -> scp -> Expand-Archive
    -> podkit.  Local config is never clobbered because mkdist packs git-TRACKED
    content only and bindings/environ/glass_layout are gitignored.
  * PODTEST.EGG is not in the repo -- only podkit carries it; without it the
    launcher runs and nothing appears, with no error.
  * schtasks /run /tn BT411Run for GUI work (session 1); /end first, because a
    task already Running refuses /run with 2147946720.
  * the measured panel identities (below).

PANEL IDENTITY, measured over SSH (WMI is session-independent, so no GUI needed):
the cab's two RAR0005 panels SHARE one EDID code and have blank serials --
exactly the collision flagged as unproven in ec080cd -- so monitor:id:RAR0005 is
ambiguous and they must use the per-connector form (monitor:id:UID224795 /
monitor:id:UID200195).  The Dell 1908FP's code is unique.  The cab's shipped
glass_layout.cfg still uses the fragile monitor:DISPLAY4 device-name form.

Joe DiPrimaandClaude Opus 5 c1a87b602c bindings: ship key G action ModeCycle in the built-in default board 
ModeCycle was bound ONLY to the gamepad Start (CONTROLS.MAP), and bindings.txt
carried no action bindings at all -- so a KEYBOARD-ONLY player could not reach
the control mode.  That is the control the torso-twist fix has to be tested
through, and it is a shipped gameplay feature (Basic steers with the stick and
auto-centres the torso; Standard/Veteran twist the torso and steer with the
pedals), so it should not be gamepad-only.

G is free.  M is taken -- it is keypad button 0x02.

DELIBERATELY the default TEMPLATE only, not a bindings-board bump.  content/
bindings.txt is a per-machine runtime file (gitignored) and an existing one is
never overwritten, so:
  * a FRESH extract writes the new board and gets G -- which is the zip flow;
  * an EXISTING tester keeps their file, and their customizations, untouched.
Shipping it to existing files means bumping "# bindings-board" and extending
kHistoricalDefaultRows so board-2 rows are recognised as "the old board" rather
than player customizations.  That is the designed path, but it rewrites every
tester's bindings file, and doing that in the same build as a large unverified
fix pile is how you lose a playtest evening.  Left for a build where it is the
headline change.  Testers on an existing install can add the one line by hand.

Joe DiPrimaandClaude Opus 5 990ad52563 podprobe: emit boot-STABLE panel identities + ready-to-paste monitor🆔 lines 
Adds a section resolving each screen's panel identity via the SAME Win32 API the
game uses (EnumDisplayDevices on the display's MONITOR child) rather than the
WmiMonitorID query above -- if probe and engine read different sources the
printed fragments could fail to match what the engine tests.  Verified on the
dev box: probe and engine emit byte-identical identities.

Answers the open [T3] multi-panel question WITHOUT deploying a build (pure OS
data).  When one EDID code appears on SEVERAL panels (identical MFD models) it
detects the collision and emits the per-connector UID form instead.

Joe DiPrimaandClaude Opus 5 ec080cd61d pod displays: bind glass panels to EDID identity, not to Windows' shifting display numbers 
Nick, after re-cabling + rebooting the pod: "the order changed ... sometimes
they change when one gets turned off and back on, at least how windows SEEs
them, even if the visual desktop tool looks the same."

Both existing binding forms are boot-fragile: `monitor:2` is an ENUMERATION
INDEX and `monitor:\.\DISPLAY4` is a GDI name Windows reassigns.  Neither
survives a panel power-cycle.  (His gos-displays.txt shows the same trap next
door in GameOS: -tmon takes DIRECTDRAW device indices -- not Windows monitor
numbers -- and a NULL-device merge shifts every index down by one on top.)

FIX: bind to the panel's own hardware identity.  EnumDisplayDevices on a
display's MONITOR child returns a DeviceID embedding the EDID manufacturer +
product code and the connector instance; neither moves across a reboot.

  DISCOVER  BT_GLASS_IDS=1 logs every attached panel's stable-id AND a
            ready-to-paste `cfg form = monitor🆔<fragment>`.  It prints the
            VOLATILE identifiers alongside on purpose: run it either side of a
            power-cycle and index/device move while stable-id does not.
  BIND      Heat MFD=monitor:id:AUO10ED,bare

NOTHING CHANGES BY DEFAULT -- no env and no `id:` prefix means identical
behaviour; `monitor:<name|index>` and raw x,y keep working, so playtester glass
builds are untouched.

An `id:` that matches nothing WARNS and falls back to computed placement.
Silence would put a picture on the wrong glass and look exactly like the bug
this form exists to prevent.

VERIFIED on a 1-monitor dev box (the pod is offline), end to end:
  * discovery printed
      stable-id = \?\DISPLAY#AUO10ED#4&31323a6c&1&UID265988#{e6f07b5f-...}
      cfg form  = monitor:id:AUO10ED
  * `Heat MFD=monitor:id:AUO10ED,bare` resolved and CENTRED correctly
      [glasswin] 'Heat MFD' bound to monitor 0,0 1920x1080 -> window at 640,300
  * a bogus id warned instead of misplacing.
The EDID-code extractor is deliberately STRUCTURAL (3 letters + 4 hex digits,
tokenising on \ # ?) rather than positional: the first cut walked separators by
position and returned EMPTY for the `\?\DISPLAY#...` interface-name form, which
is exactly the form this machine produces.  Which form you get depends on
whether EDD_GET_DEVICE_INTERFACE_NAME succeeds, so both must parse.

STILL UNPROVEN [T3] -- the pod is offline: multi-panel disambiguation when
several MFDs share one model (EDID codes collide).  The documented answer is a
longer fragment from stable-id, whose UID/instance tail differs per connector,
but that needs the cab to confirm.

Joe DiPrimaandClaude Opus 5 9657fbb11e control mode: REPRODUCE the "centering fought my control" fight, and prove the fix in Sauron's config 
Follow-up to 4ccc2a7, which fixed the mechanism but could not reproduce the
field symptom.  His fuller wording -- the centering "FOUGHT" his control, not
"the torso died" -- is what cracked it.

WHY "FOUGHT" IS THE PRECISE SYMPTOM.  TorsoSimulation's frame order is
  1. digital twist commands   -> currentTwist += d;  recenterActive = 0
  2. centerCommand > 0        -> recenterActive = 1        (re-armed)
  3. analog twist axis != 0   -> currentTwist += d;  recenterActive = 0
  4. if (recenterActive)      -> Recenter(dt)              (drags toward 0)
Desktop/glass torso input is ANALOG (Q/E -> gBTTwistAxis -> stickPosition.x), so
with centerCommand stuck the torso HOLDS while you are actively pushing (step 3
clears the arm) and snaps back the instant you ease off (step 2's arm survives
into step 4).  You can only hold it off-centre by pushing continuously.  That is
"the centering fought my control", exactly.

WHY IT ONLY BITES THE GLASS/POD BUILD -- and why the first bench came back clean.
The ONLY caller of ClearRecenterCommand() sits INSIDE the desktop key-bridge
block, gated on `gBTDrive.forced || !BTRIODevicePresent()`.  With a RIO present
-- and on glass builds PadRIO IS the rioPointer -- the bridge is OFF and NOTHING
ever clears centerCommand, so one pass through Basic pins it at 1 for good.  A
plain desktop build clears it every frame and self-recovers.
The first modecycle.sh run needed BT_KEY_BRIDGE=1 to make the mode-cycle hook
run at all -- and that same flag switched on the only thing that clears the cell,
masking the bug under test.  The hook is now deliberately OUTSIDE that block so
the bench can run the RIO-present configuration.

MEASURED A/B, bridge OFF (Sauron's config), BT_TWIST_PULSE deflect/release:

                          LEGACY                      FIXED
  ctrCmd=1 samples        310  (latched for good)     0
  twist during RELEASE    decays 0.443->0,            HOLDS 2.44346
                          0.900->0.436  (recen=1)
  recen=1 samples         permanently armed           14 (one-shot per Basic
                                                      entry, then self-clears)

So the authentic one-shot re-centre still happens on entering Basic; it just
settles instead of fighting the pilot forever.

New bench hook BT_TWIST_PULSE=<n>: deflect the analog twist axis for n ticks
then RELEASE for n ticks, repeating.  BT_LOCK_SWEEP never releases, so it cannot
show this symptom at all -- the release window IS the measurement.

Joe DiPrimaandClaude Opus 5 4ccc2a7eec control mode: Basic re-centre used the STICKY held-button cell -- and the elevation-limit swap was never ported 
Sauron: "toggled through advanced controls from standard to advanced and back
to standard -- lost torso control."

The cycle is 0 Basic -> 1 Standard -> 2 Veteran -> WRAPS TO BASIC, so getting
from "advanced" back to Standard PASSES THROUGH BASIC, whose arm re-centres the
torso.  @004afbe0 is a complete spec and the port got three things wrong:

    iVar1 = mech+0x438 (TORSO)        iVar2 = mech+0x5b4 (HUD)
    if (mode == 0) {                                 // BASIC
        *(iVar1 + 0x1f0) = 0;                        // analogTwistAxis
        *(iVar1 + 0x274) = 1;                        // recenterActive
        *(iVar1 + 0x220) = *(iVar1 + 0x228);         // vertLimitTop
        *(iVar1 + 0x224) = *(iVar1 + 0x22c);         // vertLimitBottom
        *(iVar2 + 0x2a0) = 1;                        // HUD flickerActive
    } else if (mode - 1U < 2) {                      // STANDARD/VETERAN
        *(iVar1 + 0x220) = *(iVar1 + 0x230);
        *(iVar1 + 0x224) = *(iVar1 + 0x234);
    }

1. WRONG CELL.  Basic called CommandRecenter() -> centerCommand (@0x208), the
   HELD-BUTTON cell: TorsoSimulation re-arms recenterActive from it EVERY frame
   it is non-zero, and only the input path clears it -- a mode switch has no
   button release to follow.  Digital twist commands are processed BEFORE the
   centerCommand block, so while it is set they are overridden as fast as they
   are applied: the torso stops responding.  The binary sets recenterActive
   (@0x274) directly -- a ONE-SHOT that self-clears on settle
   (`recenterActive = Recenter(dt)`) and is cancelled by any twist input.
2. THE ELEVATION-LIMIT SWAP WAS MISSING ENTIRELY.  Two authored pairs exist --
   BASIC @0x228/@0x22C (full top, HALF bottom) vs STANDARD/VETERAN @0x230/@0x234
   (the full pair) -- and all four members were ctor-written and read by NOTHING.
   Basic never restricted downward travel; the assisted modes never restored it.
3. Basic also raises the HUD's flickerActive (@0x2A0) so the horizon re-settles
   with the torso it just re-centred.  Not ported.  (New BTSetHudFlickerActive
   bridge in hud.cpp -- mechmppr sees Subsystem*, not HUD.)
Also removed an invented SetAnalogElevationAxis(0); the binary zeroes only 0x1F0.

MEASURED A/B (scratchpad/night13/modecycle.sh, LEGACY=1 for the old path;
BT_LEGACY_MODE_RECENTER=1 is the revert switch):

    ctrCmd=1 samples   legacy 26   fixed 0
    vLim pairs         fixed run shows BOTH -- (-0.698..0.349) = -40..20 deg
                       assisted, and (-0.349..0.349) = -20..20 deg Basic.
                       Before this commit only the ctor pair ever appeared.

WHAT IS *NOT* PROVEN.  I did not reproduce Sauron's PERMANENT loss.  In this
bench the legacy latch is periodic, not sticky:

    ..........LLLL......LLLL......LLLL......LLLL......LLLL......LL

because the desktop key bridge writes centerCommand every frame and zeroes it
when no button is held, so it self-recovers.  The torso IS locked while the cell
is set, which is the symptom -- but whether it stays locked depends on the input
path OWNING that cell.  On the glass/pad route (Sauron's) nothing may clear it,
which would make it permanent.  So: mechanism fixed and binary-grounded, exact
field persistence unverified.  Field-verify by cycling modes on a pad build.

Probe: the BT_TORSO_LOG gate line now carries ctrCmd / recen / vLim.
Bench hook: BT_MODECYCLE_EVERY=<n> cycles the mode from the mapper (the pod's
own route is console key 0x13d -- not a RIO button, so BT_BTNTEST cannot press
it, and mech4's BT_MODECYCLE_TEST counter did not advance in a solo run).
NOTE the bench needs BT_KEY_BRIDGE=1: with a PadRIO present the key-bridge
block that consumes the cycle is skipped.

Joe DiPrimaandClaude Opus 5 cacca58836 #148 is NOT A BUG: a peer mech does not tick before RunningMission -- by engine design 
Chased to the bottom instead of stopping.  The answer is that there was
nothing to fix, and my bench was lying to me.

Entity::Execute (ENTITY.cpp:556, real engine source [T0]) calls PerformAndWatch
ONLY when the app state is RunningMission/EndingMission or the entity
IsPreRunnable(); otherwise it merely WriteSimulationUpdate()s.
Entity::DefaultFlags is DynamicFlag|MasterInstance -- no PreRunFlag.  Only
Player and Director add it, and Mech::Reset sets it for a reset MASTER ("a
reset master must tick").  A REPLICANT mech never gets it.

So a peer mech performs ZERO subsystem ticks until the round actually starts,
however much correctly-replicated data is arriving.  Measured on the observer:

     235  [perf-first] mech 3:161 master      <- own mech, immediately
     402  [torso-rec-rx]                      <- peer torso records arriving
    2754  [perf-first] mech 2:55 REPLICANT    <- peer's FIRST performance
    2758  [torso] PushTwist COPY              <- its torso ticks 4 lines later
    2761  [ent-exec] state=5                  <- RunningMission

The peer starts performing exactly at the RunningMission transition.  That is
the engine doing what it says.

WHICH MEANS THE PREFIX WAS A BENCH ARTIFACT.  BT_AUTOFIRE starts shooting
immediately, during WaitingForLaunch -- something no player can do in a real
match -- so those 60 leading salvos measured a peer whose torso had never run.
Every "ZZZZ...XXXX" pattern in this investigation was that, and the first X
lands within a few lines of the state transition.  #141's fix is unaffected and
remains verified: the segment-cache defect was real and mid-match.

Chain of things ruled out on the way, all measured:
  * record CADENCE is authentic -- sends on RATE CHANGE (payloads are the sweep
    extremes, rate flips sign), peer dead-reckons between them.  12 records for
    12 reversals is correct, not starved.  My "only 13 records" premise was wrong.
  * ComputeTargetTwist clamp -- limits load fine on the copy (+/-2.44346).
  * the torso's own executable flag -- restoring the engine's instance branch
    (f36f013) is a genuine fidelity fix but moved this by nothing.
  * the replicant entity IS offered to the performer, executable=1, from line
    171 -- 2500 lines before its first PerformAndWatch.  The gate was inside
    Execute, not the scheduler.

Adds [perf-first]: a ONE-SHOT per-mech receipt naming entity ID + instance at a
mech's first performance.  Every other per-frame receipt in mech4 is anonymous,
which is precisely why this took so long in a 2-node log -- master and replicant
lines were indistinguishable.  Name the mech.

Gotcha #29 records the bench-design rule this cost: judge a 2-node bench by
PREFIX vs INTERLEAVED, never by raw percentage, and check [ent-exec] state=
before suspecting replication.  missileframe.sh carries the same warning.

#148 to be closed as not-a-bug.

Joe DiPrimaandClaude Opus 5 f36f0136c8 #148: restore the ENGINE's replicant instance-branch in the Mech subsystem tick 
Correct on its own merits as a fidelity fix; it is NOT the cause of #148, and
I am not claiming it is.

Entity::Perform (ENTITY.cpp:733-793, real engine source [T0]) picks the
executable predicate BY INSTANCE:

    if (GetInstance() != ReplicantInstance)  IsNonReplicantExecutable()
    else                                     IsReplicantExecutable()

and the two differ exactly on the replicant case (SIMULATE.h:195-206):

    NonReplicant : (flags & DontExecuteFlag) == 0
    Replicant    : (flags & DontExecuteFlag) == 0 || lastUpdate >= lastPerformance

`ExecuteOnUpdate()` SETS DontExecuteFlag -- it means "do not tick me every
frame, tick me when an UPDATE ARRIVES".  Mech's reconstructed tick loop used
the NonReplicant predicate for EVERY mech, dropping the branch, so on a
replicant any ExecuteOnUpdate subsystem could never run however many records
arrived.  Restored.

Measured: it does NOT move #148 (first TorsoCopySimulation call 1014 -> 1006,
noise).  So the torso's own flag was not the gate.  Keeping it because the
engine source is unambiguous about what the loop is supposed to do.

WHAT #148 ACTUALLY IS, now much better characterised:

* The record CADENCE is authentic -- my original "only 13 records" framing was
  wrong.  Payloads are the sweep EXTREMES with `rate` flipping sign each time
  (atUpd 0.0437, 2.3558, -2.3928, 2.3854, ...): the master sends on RATE
  CHANGE and the peer dead-reckons `atUpd + rate * elapsed` between them.  12
  records for 12 direction reversals is correct, not starved.

* The real defect is that the peer's copy torso PERFORMANCE does not run at
  all until log line ~1006, while its first record arrived at line 205 -- ~800
  lines of correctly-replicated twist integrated by nobody.  The first tick
  coincides with the replicant's MODEL bring-up, not with record arrival:

      [loadclips] end: fScale=0.8 ... hasGimpClips=1
      [clipfix] mech 05769358 -> EXTERIOR (lean)
      [torso] PushTwist COPY node=057A3C68 type=1 twist=-1.52319

  so the gate is above the subsystem level, in replicant model/clip init.
  Not yet found; #148 stays OPEN.

Also: [torso-copy] logs on call #0 (s_cl++ % 120), so its first line IS the
first Performance call -- that is what makes the 205-vs-1006 gap readable, and
it is why the earlier "first copy currentTwist != 0 at 1016" reading was a
SAMPLING artifact, not a measurement of when the twist started.

Probe additions kept: [torso-copy] now prints limL/limR/enab (which ruled out
the ComputeTargetTwist clamp -- limits load correctly at +/-2.44346 on the
copy), and [launchframe] now prints the shooter's live torso twist so
twistDelta and its driver sit on the SAME line.  That pairing is what proved
#141 is fully fixed: every zero-twistDelta peer launch reads liveTwist=0, and
the first launch with liveTwist=-1.84061 reads twistDelta=-1.83813.

Joe DiPrimaandClaude Opus 5 eebe7e61a4 gotcha #28: hand-composing an engine-derived transform reads a stale cache (replicant-only) 
The #141 bug class, written up so it is not re-introduced.  GetSegmentToEntity
recomputes ONLY when segmentModified is set; JointedMover::GetSegmentToWorld is
what sets it -- and the binary's own GetMuzzlePoint @004b9948 goes through it
(FUN_00424da8), so every muzzle query in the 1995 image performs the
joints->segments refresh.  Four port sites hand-composed instead, one of them
commented "the faithful FUN_004b9948".

Records the four rules the investigation actually cost:
 (a) never hand-compose; call GetSegmentToWorld
 (b) never force the dirty flag to fix a stale read -- that stand-in scored
     IDENTICALLY to the faithful fix while patching only one consumer
 (c) "peer POV only" geometry bugs = suspect a cache the local render pass
     refreshes for free, before suspecting replication (it was provably fine)
 (d) a partial-looking score: check PREFIX vs interleaved before calling it
     partial -- these were a clean prefix ending when the peer first had a
     twist to carry, so the fix was complete and "64% fixed" was wrong
 (e) the probe trap: one shared static sampled every Nth call hides one of two
     alternating instances entirely

#141 closed with the full write-up; #148 filed for the torso replication
cadence (13 records in a 5-minute run) which is a separate, real problem and
likely bears on #37 and #70.

Joe DiPrimaandClaude Opus 5 e6c5ac951e #141 sweep: every hand-composed segment->world now goes through the engine accessor 
Finishing the audit the #141 fix implied.  The unfaithful pattern

    mw.Multiply(seg->GetSegmentToEntity(), mech->localToWorld);

appeared at FOUR sites, not one.  GetSegmentToEntity only recomputes when
segmentModified is already set (SEGMENT.cpp:262); the thing that sets it is the
binary's FUN_00424da8 == JointedMover::GetSegmentToWorld, which tests
AreJointsModified() and marks the whole segment table dirty.  Compose by hand
and you read whatever cache is there -- fresh on the local mech (the render pass
refreshes it every frame), BIND POSE on any replicant.

Swept (the muzzle path was fixed in f01de8c):
  * BTResolveWeaponMuzzle           -- weapon muzzle          (already done)
  * BTGetMechSegmentWorldPos @1066  -- generic segment->world bridge
  * damage-effect anchor    @2148   -- peer effects anchored to the bind pose
  * energy-beam gun port    @8916   -- SAME exposure as the missile launch:
                                       a peer's BEAM would originate from the
                                       untwisted gun port too

Repo-wide grep now shows exactly one GetSegmentToEntity call outside
SEGMENT.cpp -- JMOVER.cpp:153, which is inside GetSegmentToWorld itself, after
the refresh.  That is the correct one.

No regression (scratchpad/night13/missileframe.sh):
    master     n=165  max 2.1719  mean 1.2781  >0.1rad 100%
    REPLICANT  n=165  max 2.0907  mean 0.8201  >0.1rad  64%
and the peer failures remain a clean PREFIX with zero interleaved cases --
i.e. only the window before the peer has any replicated twist to carry, which
is correct behaviour, not a miss.

 2026-08-08 09:28:04 -05:00
Joe DiPrimaandClaude Opus 5 f01de8cbfa #141 follow-up: do it the BINARY's way -- the muzzle query IS the segment refresh 
The previous commit's fix worked but was NOT faithful: it set
ModifyJoints(True) to force the engine's dirty flag before reading the
segment.  The binary never does that.  Called out by the user; corrected.

WHAT THE BINARY ACTUALLY DOES.  MechWeapon::GetMuzzlePoint @004b9948 ends in
`FUN_00424da8(owner, segment, out)`, which is JointedMover::GetSegmentToWorld
instruction-for-instruction:

    iVar1 = FUN_00417ab4(param_1 + 0x31c);      // GetJointSubsystem()
    if (*(int *)(iVar1 + 0xfc) != 0) {          // AreJointsModified()  <- TESTED
        ... walk owner+0x300, seg+0xc = 1 ...   // ModifySegment()
        *(int *)(iVar1 + 0xfc) = 0;             // ModifyJoints(False)
    }
    FUN_0040b104(out, FUN_004244dc(seg), owner+0xd0);   // x localToWorld

So in the 1995 image EVERY muzzle query performs the joints->segments refresh,
and the flag is only ever TESTED, never set.

THE REAL DEFECT.  BTResolveWeaponMuzzle -- labelled "the faithful FUN_004b9948"
-- hand-composed `seg->GetSegmentToEntity() x localToWorld` and skipped
@00424da8 entirely.  GetSegmentToEntity only recomputes when segmentModified is
already set (SEGMENT.cpp:262), so it returned a stale cache.  On the MASTER the
render pass refreshes the local mech every frame and hid it; a REPLICANT got no
refresh, so peer muzzles sat at the BIND POSE and the missile left along the leg
facing.  Fixed at the muzzle path, where the binary puts it -- and the forced
flag in BTPushProjectile is REMOVED (the launcher calls GetMuzzlePoint just
above, so the cache is already current when the launch frame is composed).

MEASURED -- the faithful path scores exactly what the hack did, so the hack
bought nothing and is gone:

    master     n=165  max 2.1389  mean 1.2718  >0.1rad 100%
    REPLICANT  n=165  max 1.9426  mean 0.8051  >0.1rad  64%

AND THE 64% IS NOT A PARTIAL FIX -- I called that wrong last commit.  The
failures are a contiguous PREFIX, not interleaved:

    ZZZZ...(60)...ZZZZXXXX...(105)...XXXX

and they end exactly when the peer acquires a twist to carry:

    first torso RECORD received  : line 206
    first copy currentTwist != 0 : line 1016
    first CORRECT launch frame   : line 1054   (38 lines = probe granularity)

Those 60 salvos fired while the replicated twist was genuinely 0, so launching
along the body facing was CORRECT.  Once the peer has a twist, 100% of launches
carry it.  #141 is fixed.

SEPARATE ISSUE FOUND, not fixed here: the peer's copy torso takes far too long
to first reflect the master's twist -- the master was twisted from the start,
only 13 torso records arrived across the whole run, and the copy's twist stayed
0 until line 1016.  That is a torso REPLICATION CADENCE problem, and it would
also make peer torsos visibly lag -- likely relevant to #37 (MadCat torso
backwards) and #70 (twist stops after respawn).

Joe DiPrimaandClaude Opus 5 05d7b5890a #141 peer missiles: the launch frame read a STALE segment cache on replicants 
Oracle: "missiles are firing in the direction the mech feet are facing ...
and then coming around to track the target", peer POV only -- the shooter's
own view is correct.

REPRODUCED AND MEASURED (scratchpad/night13/missileframe.sh, 2-node: only A
sweeps its torso and only A fires, so every REPLICANT line in B's log is the
mirror of one A salvo).  New [launchframe] receipt prints the yaw of the
launch forward vs the BODY forward on both nodes:

    master     n=165  |twistDelta| max=2.2962  mean=1.2283  >0.1rad: 100%
    REPLICANT  n=165  |twistDelta| max=0.0000  mean=0.0000  >0.1rad:   0%

segResolved=1 on BOTH, and segYaw == bodyYaw EXACTLY on the peer.

WHAT IT IS NOT.  Both sides already pass the mount segment (mislanch.cpp:363
master, :478 replicant mirror, both `GetSegmentIndex()` from task #67), and
the peer's torso data is fine end to end: records arrive (atUpd=2.44/-2.39,
rate 0.305), the copy extrapolates correctly (cur=-2.13987 target=-2.13987
copy=1), and the copy torso demonstrably writes its joint (PushTwist COPY
twist=-1.49601).  Hierarchy is identical too: same seg 18, same parentIdx 4,
non-null parent + joint subsystem on both.

ROOT CAUSE.  BTPushProjectile composed the frame BY HAND --
`mw.Multiply(seg->GetSegmentToEntity(), localToWorld)`.  But
EntitySegment::GetSegmentToEntity (SEGMENT.cpp:262) recomputes ONLY when
`segmentModified` is set, and the thing that sets it after a joint moves is
JointedMover::GetSegmentToWorld (JMOVER.cpp:136-146), which tests
AreJointsModified() and then marks every segment dirty.  Hand-composing skips
that, so you read whatever cache is sitting there.  On the MASTER that was
invisible -- the renderer/cockpit camera call GetSegmentToWorld for the local
mech every frame, AFTER the local torso pushes its joint, so the cache was
already correct.  A REPLICANT gets no such refresh: its cache stayed at the
BIND POSE, and the twist never reached the launch direction.

FIX.  Use the engine accessor, and set the joints-dirty flag first so it
actually refreshes (by fire time the frame's render pass has already consumed
and cleared it -- measured jointsDirty=0 on BOTH nodes).

RESULT (same bench):
    REPLICANT  max 0.0000 -> 2.1145   mean 0.0000 -> 0.8252   0% -> 64%

PARTIAL, and I am not claiming otherwise.  36% of peer salvos still read the
exact-zero stale signature while the master is 100%.  Forcing every per-joint
`jointModified` flag as well (GetSegmentToParent's own gate, SEGMENT.cpp:196)
was tried and moved the number by NOTHING -- 64% either way -- so the residual
is a different cause, most likely frame ORDER (the salvo mirror running before
the copy torso has posed that frame).  Cheap form kept.

Also fixes a SAMPLING TRAP in the torso probe: PushTwist sampled one shared
static every 30th call, and with a master torso and a copy torso ticking 1:1
every 30th call is always the SAME instance -- so the probe showed only the
local untwisted torso and hid the copy's writes entirely.  Now sampled per
instance-kind, which is what made the copy's correct joint writes visible and
moved the search downstream to the segment cache.

Joe DiPrimaandClaude Opus 5 1ae57398f1 #147 range caret: NaN poisons a process-lifetime static -- and the caret's input was never logged 
Oracle: "no range finder on this drop" + a screenshot -- tick marks present,
moving caret absent, one drop, only tester affected.

Not the host, not the chassis, not his destroyed HUD.  From the four field
logs: he WAS hosting (`[lobby] host:` appears only in his log) but range
computed fine on his node (1806 nonzero samples) and the reticle built on all
6 drops; a second tester flew a Thor the same night without hosting and saw
nothing, and the ladder is shared HudSimulation/BTReticleRenderable, not
per-chassis content; his HUD was destroyed twice but for 11s and 26s only, and
a destroyed HUD costs the LOCK (_DAT_004b7ec4 = 0.75), not the caret.

THE DEFECT.  sShownRange -- what the caret binds to -- is a function-level
static in mech4's targeting step: one cell for the whole process, shared by
every mech, carried across drops, never re-seeded.  NaN is ABSORBING in

    step = trueRange - sShownRange;
    if (step >  maxStep) step =  maxStep;      // false for NaN
    if (step < -maxStep) step = -maxStep;      // false for NaN
    sShownRange += step;

so one poisoned frame makes it NaN for the life of the process.  The consumer
repeats the mistake -- BTReticleRenderable::Draw clamps with the same two
comparisons -- so NaN reaches AddPoint/ConcatMatrix and the caret + its bar
become degenerate geometry that STOPS RENDERING, while every static reticle
element including the tick marks still draws.  That is the reported symptom
exactly, and it is sticky until relaunch.

WHY NO LOG COULD SETTLE IT.  The caret's actual input had NO diagnostic
anywhere: BT_RANGE_LOG instruments the PICK (#4), and [target]'s `range=` is a
SEPARATE locally-recomputed Sqrt in the weapon-range check -- neither is
sShownRange or gBTHudRangeStorage.  Grepping the field logs for NaN returns
nothing because the poisoned variable was never printed.  Absence of the
signal was not evidence of absence.

FIX (4 parts):
  1. re-seed sShownRange when the viewpoint mech CHANGES, so a new drop starts
     at the binary's 1200 default.  Deliberately NOT on respawn -- that reuses
     the entity, and the binary does not reset the readout on respawn either.
  2. producer NaN trap -> re-seed to 1200 instead of propagating.
  3. NaN-safe consumer clamp (test x == x first) -> fall back to the authentic
     no-target peg rather than rendering nothing.
  4. BT_RANGE_LOG now prints the caret's real input at 1 Hz plus a
     "[range] NaN TRAPPED" receipt, so the next field log CAN settle it.

STATUS [T3 on the field link].  The defect and the symptom match exactly and
the fix stands on its own merits -- a process-lifetime static feeding unguarded
float geometry is a bug regardless.  But the causal link to Oracle's report is
INFERENCE: the NaN source is unidentified and this has not been reproduced.
Field-verify with BT_RANGE_LOG=1.

Joe DiPrimaandClaude Opus 5 832bec0966 hud.cpp: byte-ground the HudSimulation constants -- all five were stand-ins under guessed names 
Found chasing the Thor "no range finder" report: _DAT_004b7ec4 was documented
as two incompatible things -- the 0.75 LOCK damage threshold (mech4.cpp:6325)
and a "heat threshold for HUD page visibility" valued 0.0f (hud.cpp:59).

The .rdata settles it (reference/decomp/section_dump.txt):

     4b7ec0  8be55dc3 0000403f 0000803f 0000c842
     4b7ed0  00000000

  _DAT_004b7ec4 = 0.75f    _DAT_004b7ec8 = 1.0f
  _DAT_004b7ecc = 100.0f   _DAT_004b7ed0 = 0.0f    _DAT_004b7f90 = 0.0f

mech4.cpp was right on both thresholds.  hud.cpp's whole tuning block was
wrong -- every entry a 0.0f/500.0f stand-in, and three of five names named the
wrong mechanism:

  * ec4/ec8 are the fire-control LOCK limits (own HUD host zone < 0.75 damage,
    targeted zone < 1.0), NOT heat/page-visibility.  A shot-up cockpit drops to
    "target held, no lock"; a dead zone cannot be re-locked.
  * ed0 is the shared ZERO -- the right-hand side of the range-slide Abs()
    idiom (`dt * 500.0 <= 0.0` picks the sign) and of an `== 0.0f` test at
    @0x28C.  The 500 m/s slide rate is an IMMEDIATE (0x43fa0000).  The old
    "MaxTorsoSlew = 500.0f" read that backwards.
  * f90 (FlickerFloor 0.0f) was the only correct entry.  Its decay RATE is the
    object's own @0x298, not a constant -- the step-6 banner said "up to
    MaxTorsoSlew (500/sec)" and is corrected too (hud.cpp:229 already had it
    right, so the file disagreed with itself).

All four wrong constants were DEAD (zero code uses; MaxTorsoSlew appeared only
in a comment), so this changes no behaviour -- it stops the next reader
trusting them.  Renamed to what they are: LockOwnZoneDamageLimit,
LockTargetZoneDamageLimit, RangeBias, HudZero.  Builds clean.

GAP FOUND, filed not fixed: HudSimulation subtracts _DAT_004b7ecc (100.0f)
from RangeToTarget@0x1EC every frame while the timed flag @0x22C is set
(timer @0x21C accumulates to @0x1D8, then both clear).  Our targeting step
does the 500 m/s slide but never this bias, so the authentic timed -100 m
range offset is missing.  What sets @0x22C is unidentified.  -> open-questions.

KB swept: no context/ or docs/ file repeated the wrong constants (gauges-hud's
0-1200 ladder / 500 m/s / pegs-at-1200 claims are all correct); the error was
confined to hud.cpp.  gauges-hud.md gains the byte-grounded table + the gap.

Joe DiPrimaandClaude Opus 5 7b003243ae #146 respawn: release the DESKTOP throttle -- and close #137, which was never a bug 
#137 ("respawn came back with MYOMERS heat MAXED", Oracle; "overheating
generator D", Sauron) sent us through a full two-sided audit of Mech::Reset
and the whole RTIS chain.  Both sides were correct.  The answer was in the
field log all along, one line after the reset:

    [respawn] Mech::Reset 3:30 healed+moved to (...) alive=1
    [techstat] ... every live condition CLEARED
    [techstat] Myomers condition 3 SET        <- Overheating, immediately
    [mppr] in thr=1 -> ...
    [gaitSM] cycleSpeed=14.6 state=12         <- already RUNNING
    [techstat] Condenser5 condition 3 SET     <- "dumping into coolant loop 5"
    [techstat] GeneratorD condition 3 SET     <- Sauron's generator D

The mech respawns STILL UNDER POWER and earns the heat honestly.  Two facts
close it:

1. condition 3 is an OPERATING flag, not an alarm.  Census over one match:
   LLaser_2 33 SET / 33 CLEARED, LLaser_1 31/31, SRM4 26/26, PPC_2 18/18 --
   every volley trips it and clears it.  EVERY subsystem is balanced
   (GeneratorD 5/4, Myomers 5/4, Condenser5 1/1; the extra SET is only the
   log ending mid-heat).  cond 6 BadPower behaves the same (Myomers 8/8).
   Nothing latches.  A post-respawn SET is not evidence of anything.

2. Mech::Reset's subsystem loop starts at index 2 and the ControlsMapper is
   index 0, so the throttle is never reset -- and the BINARY does the same.
   That is right for a pod: the throttle is a PHYSICAL lever still under the
   pilot's hand.  Respawning under power is authentic and stays.

Oracle's read that the myomer heat rate "felt right" was correct.

WHAT IS a real defect (#146), desktop only: the glass bridge merely EMULATES
that lever, with the static ramp accumulator sLever (mech4.cpp:3250) zeroed
ONLY by the X all-stop and a direction-crossing snap.  A pad/keyboard pilot
is physically holding nothing and cannot see the lever, so they respawned at
speed for no reason they could perceive -- and ate the heat load above.  The
Thrustmaster/RIO path was never affected: InterpretControls (@004d2150)
rebuilds throttlePosition every frame from the databound throttleForward.

Fix: queue the existing all-stop at Mech::Reset, reusing the proven path
(it already clears the zero-crossing detent too).  LOCAL VIEWPOINT MECH ONLY
-- gBTDrive is the local bridge's state and Reset also runs for replicants,
so an ungated write would all-stop the player whenever a REMOTE mech
respawned.  Pod-safe besides: with a RIO present the key bridge is off and
gBTDrive.throttle is never read.  BT_NO_RESPAWN_THROTTLE_RELEASE=1 reverts.

Benched 2-node (scratchpad/night13/throttlerespawn.sh): the release fires
1:1 with local respawns on both nodes independently (A 2/2, B 1/1) and never
spuriously.  HONEST LIMIT: the viewpoint gate was NOT stressed -- B ran
Mech::Reset 0 times for A's mech, so the remote-respawn path never fired.
The gate is correct by construction (the isPlayerMech idiom), not proven.
BT_AUTODRIVE cannot test the lever itself (forced mode reads forcedThrottle,
never sLever), and the zeroing path is the X button, proven in the field.

Also keeps BTReportHeatAtReset (heat.cpp, BT_HEAT_LOG): the [heat-t] census
runs on a 5s timer, far too coarse to sample AT the reset.  It is what
proved every roster subsystem including all six Condensers sits at T=77
start=77, and it corrected an earlier false negative from filtering on
IsDerivedFrom(HeatSink).

KB: context/decomp-reference.md gains the routine/self-clearing condition
semantics + this post-mortem, so it is not re-chased; cross-ref in
context/gauges-hud.md.

Joe DiPrimaandClaude Opus 5 5b7e481913 scoring: mech+0x354 is VESTIGIAL -- label it so nobody "finishes" it 
MECH_DAMAGE_BIAS(m) returned 0.0f under a comment reading "bring-up: factor =
0*bias+1 = 1", which invites a future session to wire it up.  Auditing
Mech::Reset settled what it actually is, and 0.0f turns out to be EXACT:

  * mech+0x354 has exactly ONE writer in the image -- Mech::Reset (@0049fb74,
    part_012.c:14340).  Nothing touches it during play.
  * Reset computes mean(zone + 0x158) across every damage zone, AFTER the zone
    heal has already zeroed those cells.  So it is ~0 the moment it is written,
    stays ~0 for the mech's whole life, and is recomputed as ~0 next respawn.
  * It has exactly ONE reader -- CalcInflictedScore (@004c052c,
    part_013.c:19055) -- as `avg * role.damageBias + 1.0`.

So the factor is 1.0 for the entire game and the stand-in reproduces the
binary exactly.  0x358 and 0x35c are the same computation over subsystem zones
and have NO reader at all.

This also raises confidence in the night-13 scoring work: the 505.88 kill award
was not right DESPITE a missing term -- the term genuinely is 1.0.  Wiring
0x354 to live accumulated damage would silently inflate every inflicted and
kill award, and both chart-verified numbers (+1 a damage point, +500 a kill)
assume 1.0.

Comment rewritten at the macro; combat-damage.md carries the same finding [T1].

Joe DiPrimaandClaude Opus 5 1f0923747b Mech::Reset: restore the POSTURE clears the port had dropped (#142) 
Oracle: "crouch wasn't resetting on respawn ... mechs always spawn standing".
Correct -- Mech::Reset (@0049fb74) stands the mech up and the port cleared
none of it:

    *(this+0x398) = 0             duckState
    Set_Alarm_Level(this+0x39c,0) legStateAlarm  -> standing
    Set_Alarm_Level(this+0x714,0) bodyStateAlarm -> standing
    *(this+0x650/0x654/0x658) = 0 death + leg/body reset latches
    *(this+0x5ac) = 1.0f          idleStrideScale

A pilot who died CROUCHED came back crouched -- leg parked in 'sqd' -- and now
that the cockpit strip works, showing the up-arrow "press to rise" frame on a
standing mech.

Benched (crouchrespawn.sh): A squats, dies while down, respawns -> legLvl 0
(standing) after Mech::Reset.  Weak but the failure mode (stuck legLvl=1) is
absent.  NB the first attempt was void: force-damage kept A dying before it
could crouch (legLvl 22/24 = death clips), so the run tested a STANDING death.
Switched to self-damage so the mech is stopped long enough to crouch.

Also carries the #142 gauge work: the crouch strip is a BUTTON-STATE indicator
(grey unavailable / orange down-arrow ready / orange up-arrow crouched),
decoded by rendering BDUCK.PCC rather than inferring it; and the gauge
factory's missing-image path no longer uses the no-op DebugStream.

Joe DiPrimaandClaude Opus 5 03c4d55672 #142 crouch: duckState is a THREE-state posture -- the strip is an animation 
Operator confirmed on screen: bduck.pcc is a real duck ANIMATION, and stepping
duckState 0->1->2 plays it.  So the attribute is not a flag:

    0 = standing        1 = moving between        2 = crouched

Everything else was already right -- asset, element (OneOfSeveralPixInt
@004c5204), factory registration, L4GAUGE.CFG:5001, and the attribute binding
(new [gauge] receipt confirms 'bduck.pcc' frames=3x1 attr=BOUND).  We were
writing a two-value flag into a three-frame strip, so frame 2 was unreachable
and the cockpit saw a snap: "it lights up and sticks, no animation".

The handler is back to the binary's exact write (duckState = 1, @0049fa00).
That value now MEANS the middle frame, so the press gives immediate visual
feedback and the earlier toggle divergence is retired.

Needed a separate duckRequest cell, which I tried twice to avoid:
  * duckState cannot be both the request and the display.  Settling it to the
    real posture destroys the request, so on the frame the squat clip parked
    the consumer read "crouched + pending" and issued the opposite direction --
    69 transitions from 2 presses, benched, twice.
  * reading the CACHED legAnimationState instead of the alarm made it worse:
    the cache refreshes only at the top of AdvanceLegAnimation, so right after
    SetLegAnimation it still reads the old state.  Read the alarm.
duckRequest is port-only, appended, never read by offset.

Also fixes a silent failure in the gauge factory: the missing-image path used
DebugStream -- the no-op ReconStream (project gotcha) -- so a strip that failed
to load reported NOTHING.  Now DEBUG_STREAM, plus an ungated one-line receipt
per element naming the image, frame grid, port and whether the attribute BOUND
or came back NULL.  That receipt is what proved the element was healthy and
sent me looking at the value instead of the plumbing.

Benched (crouch142.sh, madcat): 2 presses -> exactly 2 transitions,
SQUAT -> parked (settles to 2) then RISE (settles to 0).  Refusal while moving
still holds (posture=0, authentic per Lynx).

Joe DiPrimaandClaude Opus 5 fcd1a0ca8d #142 crouch: refuse-and-snap, not queue -- and honour the must-be-stopped rule 
Fixes a regression I introduced in 59f53da.  That revision retried the request
when the posture gate was not ready, which is worse than the drop it replaced:
benched, a crouch tapped at a walk QUEUED for 41 seconds (41 [duck] WAITING
lines) and would fire the instant the pilot stopped -- while duckState stayed
1, so the cockpit symbol read "crouched" for the whole time a STANDING mech
walked around.  duckState is what the gauge strip draws; it has to tell the
truth.

Now: if the gate refuses, snap desired back to actual (duckState = duckActual)
and say so once, throttled.

This also confirms the authentic rule rather than assuming it.  Benched, a
crouch pressed while driving gives posture=0 and no squat -- exactly Lynx:
"When a mech STOPS, crouch button lowers its stance."  Immobilization while
crouched looks EMERGENT rather than gated: the leg channel parked in 'sqd'
produces no root motion to travel on, and the operator's read ("i think you
cant walk when you crouch") matches.  No [skate] in the driving case either.

Also guards re-issue: while 'sqd'/'squ' is playing (legAnimationState 2 or 3)
the transition owns the channel, so want != actual no longer re-fires
SetLegAnimation every frame.

Benched both cases:
  stopped  duckState -> 1 (crouch) -> SQUAT -> holds -> -> 0 (rise) -> RISE
  moving   REFUSED (not stopped): posture=0 ... duckState 1 -> 0
           0 squats, 0 queued waits

Joe DiPrimaandClaude Opus 5 59f53da07b #142 crouch: duckState is the POSTURE the cockpit animation reads 
The crouch symbol animation is fully present and we were starving it.

    ATTRIBUTE_ENTRY(Mech, DuckState, duckState)     attribute 0x37

A 3-frame mech symbol beside the CROUCH button, indexed by duckState -- the
standing<->crouching animation Lynx and Draco describe.  It never played
because the consumer zeroed duckState the frame after the press, in BOTH
directions, so the strip sat on frame 0 with a one-frame blip to frame 1.
That is the field report verbatim: "button flickers sometimes on press ...
state does not change.  Remains in stand mode."

THE ZEROING WAS OURS.  Every writer of +0x398 in the export is the
DuckRequest handler (=1) and Mech::Reset (=0).  FUN_004a9b5c -- the master
perf, which contains the address the old comment cited as "the DuckRequest
consumer (@0x4aa011)" -- does not reference 0x398 at all.  mech.hpp's own note
already said "duckState has NO code reader anywhere in the decomp ... whatever
consumes it consumes it through DATABINDING".  The databinding consumer is
this gauge strip, and we were clearing it behind the gauge's back.

Restructure: drive on DESIRED vs ACTUAL.  duckState is the desired posture;
the parked leg alarm is the actual.  Act only on a mismatch -- no re-fire, and
nothing clears the attribute.  A frame where mapPosture is not ready now
RETRIES (throttled [duck] WAITING) instead of silently dropping the request,
which retires the old "request consumed, posture=N" miss as well.

ONE DOCUMENTED DIVERGENCE: the handler now TOGGLES.  The binary writes a bare
1 and clears the cell only in Mech::Reset, with no per-frame reader, so a
second press could never rise -- and a pod pilot's second press must un-crouch
(Lynx: "Mech is immobilized until crouch is pushed again, and mech rises").
One cell, same meaning, noted at the site.

Benched (crouch142.sh, madcat):
  duckState -> 1 (crouch) -> SQUAT -> [holds 1 while crouched] ->
  duckState -> 0 (rise)   -> RISE
Value now persists across the crouched period instead of blipping, so frames
0/1 of the strip are reachable and stable.  Also removed the interim REQUEST
DROPPED receipt: after the restructure nothing is dropped, and a receipt that
says otherwise is a trap for the next session.

STILL OPEN on #142: no immobilization while crouched (Lynx) -- nothing gates
movement on duckState or the parked leg alarm.  A driven mech with a parked
leg channel is the [skate] signature (#52), so it may not be cosmetic.

Joe DiPrimaandClaude Opus 5 0530366687 #142 crouch: the mech is fine -- it is a missing PANEL ANIMATION 
Benched solo AND in MP on the same chassis: both presses reach
DuckRequestMessageHandler, zero drops, SQUAT -> squat clip parked -> RISE.
Locomotion is not the bug, and MP is not refusing it.

Added an ungated [duck] REQUEST DROPPED receipt at the consumer's silent miss.
The squatCapable==0 path skips the consumer entirely AND leaves duckState
latched at 1 with NO log today; the posture-gate miss logged only under
BT_DUCK_LOG, which no player sets.  Neither fired on madcat.

What the pilot sees, traced with BT_LAMP_LOG: the button lamp is momentary
press feedback, not state --

    PRESS   -> [lamp] 0x13 <- 0x3c
    SQUAT   -> mech crouches, clip parked
    RELEASE -> [lamp] 0x13 <- 0x14    <-- while still CROUCHED

so crouched and standing look identical.

Era testimony corrects the scope: the button should ANIMATE A MECH SYMBOL
beside it, standing <-> crouching (operator).  Lynx: 'When a mech stops,
crouch button lowers its stance and plays crouch animation.  Mech is
immobilized until crouch is pushed again, and mech rises.'  Draco concurs.

Two real gaps, neither fixed here:
  1. no immobilization while crouched -- nothing gates movement on duckState
     or the parked leg alarm.  NB a driven mech with a parked leg channel is
     the [skate] signature (#52), so this may not be cosmetic.
  2. no stance symbol -- no gauge element draws one, and the decomp carries no
     crouch/squat/stance/duck graphic string, so it is an authored IMAGE on the
     secondary MFD; find it in that gauge's element list, not by string.

Joe DiPrimaandClaude Opus 5 61f21107b4 #108 THE EJECT GHOST: the death-edge latch tested the wrong field 
One substitution, three field symptoms.  Mech::TakeDamageMessageHandler arms
the whole death tail -- kill report, VehicleDead, death blast -- from a
was-alive-at-entry latch:

    const int deathBlastArmed = !IsMechDestroyed();   // graphicAlarm >= 9

The binary tests movementMode 9|10 there (@0x4a0303).  The port swapped in the
graphic alarm and justified it: "the death transition sets mode 9 synchronously
with the structural flag on every path through here, so the edges coincide".
True of every DAMAGE path.  False of the one that matters:
Mech::EjectPilotMessageHandler raises graphicAlarm to 10 (the EJECT state)
BEFORE dispatching its self-damage, while movementMode is still 1.  So on an
eject the handler entered already reading "destroyed", the latch never armed,
and the death tail was skipped entirely -- including VehicleDead, which IS the
respawn trigger.

Everything the field reported on night 13 follows from that:
  * "they all self destructed with panic button and didn't respawn properly"
    -- no VehicleDead, so no drop-zone hunt, so no respawn;
  * the EJECT GHOST -- the peer wrecks the mech and never un-wrecks it, because
    the un-wreck rides the master's respawn.  Normal deaths replicated fine all
    along (9 deaths -> 8 un-wrecks, benched), which is why only ejects ghosted;
  * the manual chart's "-1000 ejecting" never materialised -- the negated kill
    award and the death cost both live in the tail that never ran.

Fix: use the binary's own predicate.  MovementMode is untouched by the eject's
alarm write, so the latch arms on an eject exactly as on a combat death.

WHY SEVEN RIGS MISSED IT: the punch-out was being REFUSED, not undelivered.
EvaluateEjectPermission (@0049fa1c) grants only on
  liveWeapons < ejectMinWeapons || liveGenerators == 0 || coolantFrac < 0.05
  || (leg-gimped && !simLive)
-- armour damage satisfies none of them, and every bench ejected a healthy
mech.  An [ejecttest] receipt (2 lines) proved the dispatch fired every time
and the handler declined; the "[eject] REFUSED (mech not crippled enough)" line
was sitting in the very first bench log, ungrepped.  BT_KILL_SUBSYS's
comma-list form ("GeneratorA,GeneratorB,...") was already built for this bench.

Verified 2-node (scratchpad/night13/ejectreal.sh), before -> after:
  PUNCH-OUT landed        0 (785 refusals)  ->  1, charge=500
  peer wreck-enters       1                 ->  1
  peer UN-WRECKS          0  (the ghost)    ->  1
  eject score (type=2)    absent            ->  award=-1000.00, score 1000 -> 0
  death cost              never ran         ->  APPLYING, penalty=500

That -1000 is the manual chart's eject row to the digit: killBonus 500 plus the
500 self-damage tally, negated.

Joe DiPrimaandClaude Opus 5 29b4d68ba6 scoring: the +1000 START grant -- BT's MissionStarting override was never ported 
Seventh chart row.  BT overrides MissionStarting purely to seed the score, and
the override was missing, so MESSAGE_ENTRY(BTPlayer, MissionStarting) resolved
to the inherited engine handler (which only does the fade-in) and the grant
never happened.

    FUN_004bfbe8(player):
        base_MissionStarting(player);
        if (app->state == 4 && (player[0x29] & 0x40) == 0)
            player[0x1c8] = 0x447a0000;          // = 1000.0f

Both operands decode exactly against engine headers: application state 4 is
LaunchingMission (APP.h -- same enum whose 6 is EndingMission, already used by
the console flush), and simulationFlags bit 14 is NonScoringPlayerBit
(PLAYER.h: NonScoringPlayerBit = Entity::NextBit), so `(+0x29 & 0x40) == 0` IS
IsScoringPlayer().  Camera-ship/spectator players are non-scoring and correctly
get nothing.

CELL NOTE: the binary seeds the ENGINE cell (+0x1c8), not BT's own (+0x278) --
1995 carried two accumulators, which is why the KB suspected the pod's death
cost "may never have displayed".  Our port has one currentScore, so grant,
awards and death cost land together and the chart reads coherently.

Also resets the console watermark so a fresh mission REPORTS the grant rather
than a difference from last round's tally.

Benched: both players "[score] mission start: player N:1 seeded to 1000",
scores run 1001.98 -> 1908.64 with kills=1 (1000 + ~400 damage + 505 kill).

Also corrects a FOURTH copy of the dead-code claim, in btplayer.hpp's ScoreType
enum ("type 0 has NO scoring arm ... per-hit inflicted credit never existed").
Its byte-scan was right that no TABLE entry binds @004c0200 and wrong to
conclude unreachable -- the vtable Dispatch override calls it directly.

Joe DiPrimaandClaude Opus 5 98082e64a0 KB sweep: retire the three claims that WERE the scoring bugs 
Night 13 turned up three confident KB/source notes that each closed off a
working path, and each one was the defect:

  1. context/combat-damage.md -- "@0x4c0200 is in NO table entry: dead code",
     used to justify retiring per-hit inflicted credit in build 787.  It is
     reached through BTPlayer's Dispatch override (vtable @00513300 slot 3).
     (corrected in 2772175)
  2. context/decomp-reference.md -- "shipped content authors NO role keys, so
     the cost is 0 in the field".  Wrong on both halves: the fields come from
     the role MODEL's GameModel record, not notation keys, and dfltrole
     authors killBonus=500 / deathPenalty=500 / dmgInf=1 -- the manual's chart
     verbatim.  The cost read 0 because the role was never bound.
  3. docs/RECONCILE.md -- "role registry has no WinTesla analog -> stubbed;
     base-set scenarioRole stands".  The base ctor sets it NULL, so nothing
     stood, and Mission::GetScenarioRole IS the analog.

Common shape worth remembering: all three asserted an absence (dead code, no
authored data, no analog) and none was re-tested against the binary before
being built on.  An absence claim in this KB should carry the check that
established it.

Joe DiPrimaandClaude Opus 5 e0b91df3e1 scoring: CORRECTION -- the death cost was never missing; my arithmetic was 
Retracts the "open item" claimed in 2fcce53.  An ungated [deathcost] receipt
at the block settles it:

  [deathcost] player 2:1 advDmg=1 role=bound penalty=500 scoreBefore=-779
              -> APPLYING

It fires once, on a self-kill, exactly as it does on a combat death.  There is
no combat-vs-self asymmetry.

WHY I GOT IT WRONG: the cost is dispatched by a DIRECT
Player::ScoreMessageHandler() base call, so it never reaches the BT matchlog.
I computed the total from the LAST matchlog row and found no -500 in it -- but
that row is emitted BEFORE the unlogged cost.  I had noted the bypass one
message earlier and still failed to apply it to my own sum.  The lesson is the
usual one: a value that cannot appear in the log you are reading is not
evidence of absence.

The receipt stays.  A debit that moves the player-visible score while being
structurally invisible to the forensic log is exactly the kind of thing that
should announce itself.

Chart status after this: -500 special-case death cost VERIFIED applying.  The
-1000 eject ROW remains unverified -- its components (self-damage credit,
negated self-kill award, death cost) are each verified, but no real punch-out
has ever fired in a bench, so the total is still arithmetic.

exactly -440 + -539 = -979, with no -500 in it, despite advDamage=1 and the
role bound.  The cost is dispatched by a DIRECT Player::ScoreMessageHandler()
base call, bypassing the BT handler, so it never reaches the matchlog and only
the totals expose it.

Joe DiPrimaandClaude Opus 5 a4bfb64ace scoring: BIND the scenario role -- one commented-out line zeroed the whole chart 
BTPlayer::scenarioRole was never assigned.  The lookup sat commented out with
"the BT role registry (BTMission::GetRoleRegistry()->Lookup) has no WinTesla
analog, so the scenarioRole set by the base Player ctor stands" -- and the base
ctor sets it to NULL (PLAYER.cpp:680).  So it stood NULL forever.

Every scoring value the game has hangs off that pointer, and the shipped
content authors them correctly.  New ungated receipt in the ScenarioRole ctor
prints what a real mission loads:

  [role] 'Role::Default' model='dfltrole' killBonus=500 deathPenalty=500
         dmgInf=1 dmgRcv=0 bias=1 ff=1 return=1000

That IS the original manual's scoring chart -- +500 a kill, -500 a special-case
death, +1 per damage point.  With the pointer NULL every award multiplied
against zero: kills scored the damage tally alone (4.88), the eject charge read
0 (the field log's "PUNCH-OUT: charge=0 (role killBonus)" = #134's missing
penalty), and the death-cost block was skipped.

The analog DOES exist: Mission::GetScenarioRole(name) (MISSION.h:162) walks
scenarioRoleChain -- the same dictionary BTL4Mission fills via AddScenarioRole()
when it parses the role pages, whose own comment says the WinTesla base exposes
it.  Same lookup, same key.  Falls back to Role::Default when a creation
message names an unknown role (shipped content authors exactly one page), and
logs BOUND/NULL so this cannot fail silently again.

Benched cross-node:
  role binding    player 2:1 BOUND, player 3:1 BOUND
  KILL AWARD      505.88  (was 4.88)   <- chart's +500, verified
  death cost      victim total -500.00 <- chart's -500
  inflicted       still tracking, killer total 1017.32 kills=1

The -500 on an ORDINARY combat death is AUTHENTIC, not a bug: the binary's gate
is advancedDamageOn alone (@004c05c4 tail: `if (player+0x264 != 0) { -role+0x20 }`),
verified in the decomp.  It only shows now because the role finally binds.  It
also reconciles the chart's two death rows: an EJECT costs -500 (death) plus its
self-kill negating its own ~500 award = -1000, and an ammo death costs -500.

CORRECTION to my own earlier note: returnFromDeath=1000 is NOT the chart's
"+1000 starting the game" -- role+0x28 is a lives/return gate (`if (< 1)` ->
mission review, else respawn).  The 1000 is coincidence.  That row is still
unlocated and is most likely console-side.

Joe DiPrimaandClaude Opus 5 b2498ca39a scoring: the type-0 arm must RETURN, not break -- it was clobbering scoreAward 
Chasing the duplicate rows from 1324c81 (80 real awards + 80 reading
award=0.00).  Not a double delivery -- Entity::Dispatch sends exactly once on a
replicant.  It was the `break` I left in the delegating arm.

After delegating to ScoreInflictedMessageHandler, control fell into
ScoreMessageHandler's post-switch tail, where the LOCAL `award` is still 0:

    message->scoreAward = award;             // clobbered to 0
    BTMatchLog("SCORE", ... award=0.00 ...); // the phantom row
    Player::ScoreMessageHandler(message);    // base: currentScore += 0

Harmless to the total only because the value added happened to be zero -- but
it mutated a message on a shared path and ran a base handler for nothing.  A
later reader of scoreAward, or any side effect gained by that tail, would have
turned it into a real bug with no obvious cause.

ScoreInflictedMessageHandler is self-contained (accumulates, ForceUpdate()s,
logs its own receipt), so the arm returns.

Joe DiPrimaandClaude Opus 5 1324c81719 scoring: land inflicted credit on the OWNER's machine (Steam + console safe) 
Completes 2772175/e82f54c.  The interceptor restored the credit; this puts it
on the right node, so a player's score accumulates again.

The operator corrected two of my claims, and both were load-bearing:

1. Scores DID accumulate before build 787.  Checked: build 774 already had
   `currentScore = 0` in the console flush, so the flush was never eating
   score.  My "score zeroed every interval" theory is dropped.  The watermark
   from e82f54c stays only because it is harmless and keeps a master's own
   total intact across a flush -- it was not fixing a field bug.

2. The reroute works, and 774's own comment says so: the killer's player is a
   REPLICANT, so Entity::Dispatch reroutes to the owning host
   (ENTITY.cpp:244-251) and the credit lands on the killer's OWN machine.
   That is how kill credit has always crossed nodes.

So the earlier master-only gate was the right idea and failed for a reason I
guessed wrong.  A rerouted message arrives over the WIRE through Receive(),
which goes straight to the handler table -- the virtual Dispatch override is
never called on the receiving side.  Type 0 therefore landed in
ScoreMessageHandler's arm, which Verify-rejected it: award 0.00.

Fix is both halves:
  * Dispatch intercepts on a MASTER only -- local delivery stays exactly as
    @004bffa0 does it;
  * ScoreMessageHandler's type-0 arm DELEGATES to ScoreInflictedMessageHandler
    instead of Verify-rejecting -- wire delivery gets the same handler.
One accumulator, on the machine that owns the score.

Works for Steam today (no console tally exists -- btconsole.py/btoperator.py
handle no score at all) AND for a real operator console later: the console
flush is untouched and still ships authentic deltas under the owner's ownerID.

Benched (cross-node zone-walk kill):
  credit node      shooter's master only (victim's node banks 0)
  running total    253.60 and CLIMBING, no resets
                   (was: peaks ~35, snapping back every few seconds)
  type-0 rejects   0
LOOSE END: each real award is followed by a duplicate row with award=0.00
(80 real + 80 zero).  Harmless -- the total is unaffected -- but it means the
report is delivered twice on the owner; not yet explained.

Joe DiPrimaandClaude Opus 5 e82f54c957 scoring: the score AUTHORITY is the operator console -- and our port has none 
Follow-up to 2772175 (type-0 interceptor restored).  Benching the restored
credit exposed the next layer, and two of my attempts at it were wrong; both
are recorded so they are not retried.

FINDING [T1]: the binary flushes ConsolePlayerVTVScoreUpdate(ownerID,
currentScore) then does `param_1[0x9e] = 0` -- UNGATED.  So +0x278 is a console
DELTA, never a running total, and it does not matter which NODE computed one:
every delta is stamped with the scoring player's ownerID and the CONSOLE
accumulates.  That is almost certainly where the manual chart's "+1000 starting
the game" was seeded, which is why no game-side code grants it.

Our port has no console as score authority.  GetScore() (SCORE gauge),
CalcRanking() and the replicated Player__UpdateRecord all read +0x278 on the
OWNING node.  Damage is applied on the VICTIM's node, so block B dispatches the
inflicted report to the SHOOTER's player object there -- a REPLICANT -- and the
master's next update record overwrites it.  Benched: totals climb to ~35 and
snap back every few seconds.  THAT is the "scoring went screwy" report.

WRONG TURN 1 (reverted in spirit, kept only where harmless): blamed the console
flush and added a last-sent watermark so the console still gets deltas while
+0x278 keeps a total.  The resets were 2s apart, not on the 10s console
interval -- the timing was already in the data.  The watermark stays because it
does stop the FLUSH from zeroing a master's own total, but it was not the bug.

WRONG TURN 2 (reverted): gated the interception to MasterInstance so a
replicant would reroute to the master.  The message arrives, but the BT
extension fields (damageAmount@+0x24, senderMechID@+0x34) do NOT survive the
wire -- only the base scoreAward -- so every award computed 0.00.  That failure
is the clue to the answer: the kill report (type 2) credits cross-node
correctly precisely because its value rides scoreAward.

FIX SHAPE (not implemented -- landing it deliberately rather than guessing a
third time): compute the award on the victim's node, where the damage data
lives, and ship the RESULT in scoreAward the way the kill report already does,
instead of shipping the basis and recomputing on a machine that cannot see it.

State now = binary-faithful unconditional interception.  Re-benched: 79
inflicted rows, awards 0.98..25.00 all positive and tracking damage, 0 type-0
Verify rejections.  Cross-node banking still open.

Joe DiPrimaandClaude Opus 5 27721754da scoring: restore the type-0 INTERCEPTOR -- per-hit inflicted credit was live all along 
Players reported scoring and K/D going screwy on 4.11.817.  Cause: build 787
(#45/#134) retired the port's per-hit inflicted crediting as an "invention",
on the strength of a KB claim that the type-0 score handler was dead code.
That claim was wrong.

BTPlayer overrides Dispatch -- vtable @00513300 slot 3 = FUN_004bffa0 -- and
splits type 0 off BEFORE base dispatch:

    if (msg->id == 0x16 && msg->type == 0)  FUN_004c0200(...);   // ScoreInflicted
    else                                    base dispatch;

@004c0200 names itself in its own Verify string
("BTPlayer::ScoreInflictedMessageHandler") and computes
CalcInflicted(basis) -> negate if target==self -> x (targetTonnage/ownTonnage)
-> accumulate into +0x278.  ScoreMessageHandler's type-0 arm Verify-rejects
precisely BECAUSE this interceptor guarantees type 0 never reaches it.

The port had the handler, faithfully reconstructed, and no interceptor -- so
Block B's inflicted reports all landed in the rejecting arm and banked 0.
Per-hit damage credit was silently deleted.

Independently corroborated by the ORIGINAL MANUAL'S SCORING CHART (filed as
reference/manual/scoring_chart.webp, from Lynx): "+1 each damage point scored
on opponent's armor" and "-1 each self-inflicted point of armor damage" -- the
negate-if-target-is-self arm exactly.  Without that chart the dead-code note
would probably have stood.

Verified (scratchpad/night13/scoreverify.sh, cross-node kill, 2 nodes):
  type-0 Verify rejections   0   (was firing on every non-lethal hit)
  inflicted score rows      83   awards 0.98..25.00, all positive, tracking damage
  kill path un-regressed    type=2 award=4.88 kills=1, victim respawn x1

KB: combat-damage.md report B and the score-model paragraph rewritten, with
the full chart and THREE unreconciled rows flagged [T4] -- flat +500 kill vs
the benched 4.88, +1000 at game start, and -1000 eject / -500 ammo (which
would live in ScenarioRole::specialCaseDeathPenalty @role+0x20, read by the
port but authored nowhere in shipped content).

KNOWN, NOT FIXED HERE: in MP the running total does not persist -- currentScore
is flushed to the operator console and ZEROED (btplayer.cpp ~1219) because the
binary treats it as a console DELTA.  Restoring the credit makes that very
visible (bench: totals climb to ~35 then reset).  Needs its own decision; the
chart's "+1000 starting the game" implies a persistent total lives somewhere.

Joe DiPrimaandClaude Opus 5 4642129e76 #108 peer-side WRECK receipt: make ghosts countable 
The un-wreck receipt had no partner, so counting ghosts in a field log meant
pairing it against

    [BTrender] wreck: 'thrdbr.bgf' missing -> gendbr.bgf fallback

which is a MISSING-ASSET WARNING, not a death -- it only prints for chassis
whose wreck model is absent.  Night 13's census found ONE ghost while testers
reported many, and there was no way to separate a real count from a chassis
accident.

Emit one ungated line for every REPLICANT entering the wreck state, symmetric
with the existing un-wreck line, so a log's ghost count is exactly
(wreck-enters minus un-wrecks) per entity:

    [wreck]   replicant H:E entered wreck state (mode X->9) at (x,z)
    [respawn] replicant H:E un-wrecked + warp   (mode 9->1) at (x,z)

Verified 2-node (200s, force-damage victim): 5 enters, 5 exits, exactly
paired -- while the old marker printed ZERO times in the same run.  That gap
is the point: five real deaths, invisible to what the census was reading.

Also lands the night-13 census tooling (ghostcensus.py) and the eject benches
that did NOT reproduce, with their failure modes in the headers so the next
attempt does not repeat them: five rigs failed to trigger a punch-out at all
(BT_BTNTEST never reached the mapper for 0x3D or 0x14; BT_EJECT_AT did not
fire either).  Panic-eject replication remains UNTESTED by bench.

Joe DiPrimaandClaude Opus 5 43d30ca7e4 #140 receipts: name the corruption case in a FIELD log 
Two ungated one-liners, because no bench here reached the failing path and
the next playtest is a better instrument than more automation:

  [glasswin] destroy entry #N windows=M   -- N=2,M=0 is the double-destroy
  [glasswin] saved ... (live=L remembered=R) -- live=0 IS the corruption case
                                                (pre-cache that wrote a file
                                                holding only the plasma line)

Also lands the benches that did NOT reproduce it, with their failure modes
recorded in the headers so the next attempt does not repeat them:
layoutsave.sh (round trip -- passes on the fixed build), layoutteardown.sh
(graceful WM_CLOSE; still never reaches the dtor chain), layoutround.sh (MP
round boundary; the relay never started the mission inside the window).

Joe DiPrimaandClaude Opus 5 c04bec0a52 #140 glass_layout.cfg lost every MFD line on a desktop teardown 
Regression from d213c98 (the pod PadRIO/panel coupling fix).

BTGlassPanels_Destroy calls SaveLayout FIRST, unconditionally, before it
looks at whether any windows are left.  d213c98 added a SECOND caller
(~LBE4ControlsManager) alongside the existing one in ~PadRIO, so on the
desktop path both run: ~LBE4ControlsManager does `delete rioPointer`, which
fires ~PadRIO -> destroy #1 saves the live windows and zeroes gWinCount ->
destroy #2 then rewrites the whole file from an empty list.

Why only the MFDs vanished, which is the detail that identifies it: external
windows (plasma) already cached a last-known rect (gExtern[].haveLast) and
were written from the cache; the per-display glass windows had no cache and
were simply skipped once their HWND was gone.  Hence the reported signature,
"all the MFDs and secondary lines missing, but plasma was still there".

The pod was never affected -- no PadRIO there, so only one destroy, and it
runs BT_GLASS_LAYOUT=load off a frozen master regardless.

Two fixes, because the guard alone would leave the trap armed for the next
teardown-ordering change:
  1. glass windows get the same remembered-geometry cache the extern windows
     have, kept ACROSS teardown.  The file is now monotonic -- a save can
     update a line or add one, never drop one.
  2. the teardown save is guarded on there being windows to report.

Also corrects the comment at the L4CTRL call site, which claimed the second
call was "a no-op on the PadRIO path".  That claim is what made it look safe.

Verified (scratchpad/night13/layoutsave.sh -- the tester's round trip, not a
single launch, since the report was "saved fine, reset on relaunch"):
  run 1  one "saved 8 window position(s)" line (was two, the second wiping)
         cfg holds all 7 glass windows + plasma
  run 2  "restored 7 window position(s)", cfg byte-identical after the trip

Joe DiPrimaandClaude Opus 5 6a96fb6420 #52 the peer STANDING-LOCK: case 0's fallthrough was intercepted 
A replicant could not start walking between gait-change records.  The port's
body case 4 (the task-#64 lockstep twin) is an INSERTION sitting between case 0
and the advance group; in the binary case 4 is a MEMBER of that group
(FUN_004a5678 @004a5678: case 2,3,4,5,8,... -- no turn block, no speed exit),
so case 0's fallthrough is meant to land on Advance().  The insertion caught it.

On a replicant that is not a race but an identity: case 0 arms walk iff
standSpeed < bodyTargetSpeed, and the inserted block resets iff standSpeed <
bspd -- where bspd IS bodyTargetSpeed for a replicant.  Same expression, so arm
and reset fire on the same frame, forever, and a peer parked at Standing with a
live replicated demand never cycles.  bodyCycleSpeed stays 0 while position
advances from dead reckoning: the skate.

This is the sequel to e91d447 (#82).  Before it the replicant branch read the
dead local mapper cell (0 forever), the exit never fired, and the fallthrough
worked BY ACCIDENT.  Fixing the dead cell closed the escape hatch.

Fix: case 0 -> goto advance_body_normally, the leg twin's own idiom, restoring
the binary's structure without touching the #64/#82 turn logic.
BT_NO_BODY_FALLTHRU=1 reverts.

Measured (2-node, scratchpad/night13/skatelock.sh):
  legacy  336 consecutive locked seconds, bspd=39.2324 bts=39.2324 every line
  fixed   0 locks, every pass
  master body-Standing samples 52 -> 21 (it locked too, invisibly at mj=0)
  turn-in-place intact: pivoter body state 4 x9 / leg state 4 x8, in lockstep

Diagnostics (both keepers): [skate] now carries bstate= -- the field lines
proved "both channels idle" but never named the state, which was the whole
answer; [bodySM]/[peergait] under BT_BODY_SM_LOG instrument the arm->reset pair
and a moving replicant's body channel.

NOT claimed: that this accounts for the night-13 field episodes.  That link is
inference -- locked + translating IS the skate signature by construction, but no
bench caught the two together.  bstate= settles it next playtest.

Joe DiPrimaandClaude Opus 5 39144813a4 pod: kit carries PODTEST.EGG (it was never in the repo) 
First real new-build drop on the cart exposed it: the kit pushed environ.ini

`-egg PODTEST.EGG` and that mission only ever existed on the pod -- mkdist
ships git-TRACKED content only, so the new install had no mission to run.
Master copy now sits at C:\bt411\ with the other kit files and podkit.ps1
installs it.

Joe DiPrimaandClaude Opus 5 d213c980a9 fix: MFD panels never appeared with the HARDWARE RIO (PadRIO coupling) 
Nick ran the cab with the real board and the mission came up on the main view
with every MFD dark -- and not one [glasswin] line in the log.

BTGlassPanels_Create() was called only from the END OF THE PadRIO CONSTRUCTOR.
The panels began as the frames around the on-screen RIO button banks, so "the
buttons ride the device" was reasonable then; it is backwards on a real cab.
L4CONTROLS=RIO:COM1 means PadRIO is never constructed, so the MFD windows were
never created -- silently, since nothing is wrong from the display layer's
point of view.

The panels are a DISPLAY concern.  Creation moves to LBE4ControlsManager,
after the L4CONTROLS parse where every device branch converges, and a
symmetric BTGlassPanels_Destroy() goes in its destructor: ~PadRIO tore them
down, ~RIO knows nothing about them, and windows outliving the surfaces they
blit would crash on the next mission cycle.  Both calls are idempotent
(Create returns on gWinCount != 0), so the proven PadRIO path is unchanged
and simply arrives first.  Both guarded by BT_GLASS -- L4GLASSWIN is only in
the build when the gate is on.

Verified on the cart: hardware RIO up AND all three surfaces on their intended
displays in the same run.

Joe DiPrimaandClaude Opus 5 6fcff95010 pod: the HARDWARE RIO on COM1 (L4CONTROLS=RIO:COM1,KEYBOARD) 
The real cockpit board now drives the cab instead of PadRIO, frozen in the
profile so all five tester launchers get it.  Nothing above the seam changed
-- the 109-mapping L4 control table installs exactly as on a desktop, and the
cab keeps the GLASS display stack.  BT_PLATFORM=pod is NOT the way to this;
that would drag in the 1995 gauge path.  RIO:COM1 -> \.\COM1 at 9600 8N1.

Evidence the link is real, not just "the port opened":
  RIO successfully initialized!
  FAILURE.LOG: 4 missing boards (Slot 3:0, 3:2, 4:0, 5:0), 16 dead lamps
  [ctrlmap] push stick x=0.0595238 y=0   <- physical stick outside deadband
A specific 4-of-many board inventory is the proof: a dead serial line reports
the WHOLE address space missing.  Reproduced after deleting FAILURE.LOG.  The
dead lamps are the boards this partial crash cart does not have.

Banner honesty: "GLASS (PadRIO ...)" was hardcoded, so a wired cab reported
PadRIO on the very line you read to check which device won.  It now names the
resolved one -- GLASS (hardware RIO; plasma off [L4PLASMA]).

Recorded in pod-hardware.md, including that RIO and PAD are mutually exclusive
(both assign rioPointer, last token wins) and that a CENTRED stick reads x=0,
which is indistinguishable from no data -- so the by-hand check of stick,
throttle, pedals, buttons and the Ranger calibration is still outstanding.

Joe DiPrimaandClaude Opus 5 05d8164801 pod: make the frozen rig survive a NEW BUILD, not just a reboot 
Both frozen files live inside the versioned install and neither ships in the
zip -- environ.ini is generated on first run, glass_layout.cfg is ours.  So
Nick extracting the next build would get a cab that comes up wrong with no
error anywhere, which is exactly the failure the freeze was supposed to end.

Masters now live at the stable C:\bt411\ (podprofile.ini, glass_layout.cfg,
podkit.ps1).  setup_pod.bat pushes them into the newest BT411_* folder -- run
once per extract.  runpod.bat resolves the newest install and applies the kit
itself, so the remote launch path needs no per-build edit.  Re-tuning means
editing the MASTER: the apply overwrites the install's copy on purpose, so a
moved panel has one place to look.

Also records, for playtesting on the cab: all five tester launchers set no pod
key at all, so each inherits the rig from environ.ini without knowing the pod
exists -- verified by running play_solo.bat on the cart (7 settings applied,
not 9, because the bat sets BT_PLATFORM and BT_START_INSIDE itself and the
real environment wins).  That is the case against a separate pod-only ini: a
second file would need every launcher to opt in.

Verified: kit re-applies idempotently, and the rewritten runpod.bat brings the
cab up correct -- 9 settings, GLASS, -fit borderless, all three surfaces on
their intended displays.

Joe DiPrimaandClaude Opus 5 d96fa4f4e2 pod: BT_GLASS=1 is not a gate -- name the real one (BT_PLATFORM=glass) 
BT_GLASS is a compile-time #ifdef; getenv("BT_GLASS") appears nowhere in the
tree.  The line rode along from the bring-up launcher into the frozen profile
and into the pod-hardware runbook, reading like the switch that turns the
glass path on.  It never did anything -- the rig worked because glass is the
DEFAULT profile when nothing is set.

Replaced with BT_PLATFORM=glass (the real spelling, so the cart does not lean
on that default) and noted why NOT BT_PLATFORM=pod: the pod profile selects
the 1995 multi-surface gauge path, which needs the NVIDIA horizontal span no
modern driver has.  Behaviourally identical -- both land gBTPlatformGlass=1.

Re-verified on the cart: 9 settings applied, GLASS profile, -fit borderless,
all three surfaces on their intended displays.

Joe DiPrimaandClaude Opus 5 654277bb7b pod: freeze the ALPHA-MR rig in environ.ini (BT_FIT, L4PLASMA=NONE) 
The cart's display config was carried by a launcher .bat, so it only came up
right if the game was started one particular way.  Move it into the file the
engine already reads before anything touches the environment.

  content/environ.ini  <- scratchpad/pod/podprofile.ini, merged idempotently
                          between markers by scratchpad/pod/mergeprofile.ps1

Two gates were missing for that to be enough:

  BT_FIT=1      the env spelling of -fit, so the borderless main view does not
                depend on one launcher's command line (shortcut, scheduled
                task and autostart all have to produce the same rig)
  L4PLASMA=     NONE / OFF / 0 -> no marquee at all.  Leaving it unset does
                NOT work: the GLASS profile force-defaults it to SCREEN, which
                drops a desktop plasma window on the cab's glass.  The boot
                banner now reports the live state instead of always claiming
                "plasma window".

Also lands the bring-up engine work this depended on: monitor:<name|index>
layout binding (device-bound, not pixel-bound -- desktop rects move when a
display re-enumerates), ",bare" implying frameless, rotation-aware radar
surface sizing, BT_GAUGE_SEC_ROT accepting 0-3 (it silently forced 3 for
anything but 1), 180-degree ExpandPlaneToBGRA, and the BT_POD_CHANMAP /
BT_POD_IDENT / BT_POD_CHANTEST identification gates.

Verified on the cart, build 4.11.813, launcher carrying none of it:
  [boot] environ.ini: 9 setting(s) applied
  [boot] platform profile: GLASS (PadRIO; plasma off [L4PLASMA])
  [cockpit] -fit: borderless 800x600
  [glasswin] radar rotation 0 (none)
  ... all three surfaces on their intended \.\DISPLAYn
No [plasmawin] line in an otherwise-logging run = the ctor never ran.

KB: pod-hardware.md gains the ALPHA-MR section (mapping, the two wiring
deviations, the frozen profile, the session-0 remote-work traps) and its RGB
SPLIT "OPEN: which way is the cart wired" is now SETTLED -- it is splitter
wired, the composite is what lit it.  glass-cockpit.md documents monitor:
binding, BT_FIT and L4PLASMA=NONE.

Joe DiPrimaandClaude Fable 5 e179c7033f BT_POD_RGB: the authentic RGB-split output -- one window per VGA PORT 
Implements what the pod actually does (pod-hardware.md THE RGB SPLIT): a VGA
port's R/G/B lines each drive a separate mono MFD monitor, so a window is not
one MFD -- it is one PORT carrying up to three.  BT_POD_RGB=1 collapses the
five MFD windows into the two ports the cab drives (Port A: Comm=red,
Mfd2=green, Heat=blue; Port B: Mfd1=red, Mfd3=green) and composites each
group's planes into the colour channels, leaving the radar on its own
full-colour port.  Channel comes from the live port (GetEnableID), never a
hardcoded table, so an Eng-page swap follows automatically; BlankColor planes
contribute nothing, exactly as on the pod.  Implies BT_POD_SURFACES (bare
640x480 pictures -- the cab's buttons are physical).

Verified locally (bare windows, "RGB COMPOSITE of 2 plane(s): Comm Mfd2") and
LIVE ON NICK'S CRASH CART over the tailnet: Port A -> DISPLAY4, Port B ->
DISPLAY2, radar -> DISPLAY1, all exact-fit.  Pod scratch kit included (ssh
helper, layout cfgs for both modes, launcher; the mission-egg launcher fix --
a bare MP.EGG exits the mission loop with no relay, and BT_FE_SOLO parks at
the menu, so neither lights the panels).

Joe DiPrimaandClaude Fable 5 e0e9dcc292 KB: decode the pod's RGB SPLIT -- one VGA port drives THREE mono MFDs 
Answering 'how do the panels split RGB into 3 monitors' from primary sources
rather than inference:

- content/GAUGE/L4GAUGE.CFG (the authentic 1996 pod config) configures each
  gauge port with a bit-plane mask AND A COLOUR CHANNEL: Comm=red,
  Mfd2=green, Heat=blue on clut2 (the upper row); Mfd1=red, Mfd3=green on
  clut1 (the lower row, blue spare); sec/radar = full rgb, rotation 270 (the
  portrait CRT).  Eng1/2/3 are the engineering-page twins on the same
  monitors, swapped in/out via reconfigure() with 'blank'.
- L4GraphicsPort::BuildSecondaryColor (L4VB16.cpp) proves the mechanism at
  T0: it walks the palette entries owned by the port's bit group and writes
  exactly ONE component (RedChannel->Red, GreenChannel->Green,
  BlueChannel->Blue, AllChannels->whole triplet); BlankColor blanks the
  group.  So one palettized framebuffer emits three independent pictures on
  the R/G/B analog lines, and the splitter feeds each line to its own mono
  monitor -- which is also what the '1280x480 horizontally spanned' MFD
  surface actually is: two VGA outputs x three channels.

Port consequence recorded: the per-panel window path (BT_POD_SURFACES) is
right for per-panel outputs but WRONG for splitter-wired glass, which needs a
channel-composite mode (three planes -> one RGB image, pure primary tints).
ExpandPlaneToBGRA already does the per-plane half.  Open: how Nick's cart is
actually wired.  Also lands the pod bring-up scratch (ssh helper, layout cfg,
launcher, firestorm repo browser).

Joe DiPrimaandClaude Fable 5 99956d54e3 tools: podshell_setup.ps1 -- one-shot remote-shell setup for the pod PC 
OpenSSH server + a single authorized key + a private/domain-only firewall
rule, so bring-up can run over a tailnet instead of by hand through Chrome
Remote Desktop (CRD paints a canvas -- unreadable to tooling; text and logs
need a real shell).  Handles the Windows administrators_authorized_keys ACL
quirk, refuses to run on pre-Win10 (the period-pod case, which stays on the
clipboard/probe route), never opens the public profile, and prints the exact
ssh line including the Tailscale address.  Undo steps in the header.

Joe DiPrimaandClaude Fable 5 38b08c96d1 podprobe: run-compatibility verdict + XP-safe .bat fallback 
The crash cart may BE the period pod PC (that is where NVIDIA Horizontal Span
still exists), in which case the first question is not the display map but
whether btl4.exe can launch at all -- a modern MSVC toolset needs Win7 SP1+.
The probe now states the verdict outright, and podprobe.bat covers the case
where PowerShell/.NET is not present to run the probe in the first place
(wmic + dxdiag, both XP-era tools).

Joe DiPrimaandClaude Fable 5 67a4f09e86 POD MFD bring-up: BT_POD_SURFACES bare-panel mode + placement receipts + probe 
Nick's crash cart is the first shot at driving the real MFD panels, so the
pieces the cab needs that the desktop glass path lacked:

- BT_POD_SURFACES=1 (L4GLASSWIN): crop every display window to its SURFACE
  (MFDs exactly 640x480, radar 480x640 portrait), drop the on-screen RIO
  button banks -- the cab's buttons are PHYSICAL, so drawing fake ones onto a
  real panel is exactly wrong -- go frameless, and skip the Flight Controls
  pad entirely (6 windows, not 7).  Per-window ",bare" in glass_layout.cfg
  for mixed rigs (idempotent with the global mode).
- Placement receipts: each window logs which PHYSICAL monitor it landed on
  ("[glasswin] 'Heat MFD' surface=Heat at X,Y 640x480 bare -> monitor
  \.\DISPLAYn (...)").  Nobody can see 7 surfaces at once on a cab, and over
  Chrome Remote Desktop you cannot see the panels at all -- the log is the
  only confirmation the map is right.
- tools/podprobe.ps1: run-on-the-pod topology probe (no install/admin) --
  GPUs, every monitor's virtual-desktop rect, EDID make/model, serial ports
  (the RIO board), session type, plus a PROPOSED glass_layout.cfg assigning
  the six surfaces to the non-primary monitors.  Self-tested here (correctly
  reports a single-monitor laptop and declines to map).

Local verify: 5 MFDs at 640x480 bare + portrait radar + Flight Controls
dropped, receipts printed.  KB: pod-hardware §MFD PANELS ON REAL HARDWARE
(incl. WHY the 1995 path is not the route -- NVIDIA Horizontal Span is gone
from post-XP drivers and per-adapter exclusive fullscreen is fragile over a
remote session) + glass-cockpit env table.

Joe DiPrimaandClaude Fable 5 51dff6bd5a handoff: #60 closed (census + re-export) 
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
 2026-08-06 11:12:20 -05:00
Joe DiPrimaandClaude Fable 5 f44be87ab2 #60 PART 2: the RE-EXPORT -- dark code 90KB -> 41KB, coverage 87.3% -> 93.5% 
Installed JDK 21 + Ghidra 12.1.2 (no admin, %LOCALAPPDATA%\bt411-tools beside
DXSDK/cmake; runner uses 8.3 SHORT paths because Ghidra's .bat expands
%JAVA_HOME% unquoted and the profile has a space).

New tooling: reference/ghidra_scripts/ExportGaps.java -- ExportAll's exact
output contract PLUS a gap-fill pass (force disassembly + createFunction at
E8 call targets outside functions, data->code pointers at a plausible
prologue, and the census's discovered starts; iterated to a fixpoint,
logged to gapfill_report.tsv).  tools/ghidra_reexport.sh (headless runner,
'reprocess' mode) and tools/gapdiff.py (score two censused exports);
gapcensus.py now censuses any export dir.

Results: 6267 -> 6472 functions (+205 created in 2 rounds: 195 census
starts, 6 call targets, 4 data pointers; 56.1KB newly covered), ZERO
decompile failures.  Dark real code 90.4 -> 40.8 KB (54.8% recovered);
game-side dark 53.1 -> 21.1 KB; regions 428 -> 321.  EVERY historically
dark function now has pseudocode -- including @0x4c05c4 VehicleDead, the
absence that opened this issue.

VALIDATION: the new pseudocode confirms this week's hand reconstruction of
the crouch field-for-field (mapPosture/duckState/squatCapable/myomerEff/
novice gate/SetLegAnimation/ForceUpdate/stability alarm) -- and exposed one
branch the raw pass missed: AIRBORNE AUTO-RISE (mode 3|4 && legState 1 ->
forced squ), now implemented in mech4.cpp and re-benched un-regressed.

PROMOTION: the re-export is canonical reference/decomp/; the previous export
is preserved at reference/decomp/archive_2025export/ so old
`part_0NN.c:LINE` citations still resolve (addresses are stable across both;
line/shard membership is NOT -- cite @ADDR).

New lead recorded: @0x4c0904 is the MASTER BTPlayer Performance (team
resolution, EndMission console post, score heartbeat) -- our @0x4c083c
PlayerSimulation attribution needs a re-check.  KB: source-completeness,
gotcha #20 (the rule is cheap now -- look it up), CLAUDE.md router/layout.

tools/gapcensus.py (deterministic): index-vs-.text interval math, export
cross-check, function-start discovery inside dark regions (E8 call targets +
data-section code pointers), pad exclusion, TU attribution, repo-citation
flags. Output: reference/decomp/GAP_CENSUS.md + gap_census.tsv.

Headline: .text 892KB, index covers 87.3%; 428 dark regions = 90KB REAL code
(indexed-but-unexported = 0 -- the gap class is purely 'never indexed').
Game-side dark ~54KB: 66 regions visited by past digs, 159 NEVER TOUCHED.
Validation: all six historically-bitten dark addresses (VehicleDead,
ToggleLamp, death tail, master-perf, myomer integrator, duck consumer) land
inside census regions; the two most-cited regions are the two that produced
the most reconstructions.

Top uncharted leads (spot-checked real code): the ~9KB l4splr|btmssn cluster
(dispatch-table state machine -- likely BTMission's unexported heart); the
613B btplayer hole before the ctor (mission-review id-0x18 sender suspect);
btl4app tails; heat|mechmppr + mechweap|btplayer boundaries. Full log:
phases/phase-04-gap-census.md. Re-export half deferred (no local Ghidra;
scripts ready). KB: source-completeness census section + CLAUDE.md lookup

Corrections (wrong claims fixed + swept):
- open-questions: the DuckState 'no CODE consumer, authentic [T1]' verdict
  RETRACTED (consumer = the unexported posture block; squat clips shipped in
  BTL4.RES all along); the searchlight fog swap re-marked DONE (was 'STILL
  DEFERRED'); crouch index pointer updated.

  report tail (BTPostKillScore retired).
- pod-hardware: crouch census rows -> COMPLETE; gauges-hud: 07-20 note
  (generators 'unreconstructed') re-swept.

New knowledge:
- reconstruction-gotchas #20: EXPORT-GAP BLINDNESS (4 incidents, 2 falsely
  T1; the byte-scan/named-member/RES-TOC/manifest checklist) + the
  verification-viewpoint bullet in #13 (the crouch capture errors).
- decomp-reference: master posture/crouch block offsets (+0x3f8/+0x79c, the
  myomers cluster) + 8 new bench env gates.
- rendering: beam-material decode (btfx brighten) + look-pass acceptance.
- experience-levels: crouch novice lockout in the +0x25c consumer list.
- build-and-run: the stale-link build ritual; test-harness: bench-script
  gotchas (both previously oral tradition).
- glossary: export-gap-blindness; multiplayer: crouch/searchlight ride
  existing records; subsystems: searchlight visuals pointer.

Status refresh: CLAUDE.md front + project-overview current-state -> core
gameplay reconstruction COMPLETE (774->801), polish phase, #60 census next.

Joe DiPrimaandClaude Fable 5 e1c3f2db6a Myomer factor: correct the false 'feeder unreconstructed' claim + wire the 
crouch gate to the LIVE drive value

The myomer system was ALREADY COMPLETE (2026-07-31 seek audit): Performance
wrapper @004b8b9c, AvailableOutput @004b8ac0 (gear clamp x quadratic heat
degrade x (1 - zone damage)), and the master-perf chain walk + speedDemand
scale + turn freeze in mechmppr.cpp:990 -- the same @0x4a9cf2-0x4a9da4 bytes
the crouch dig re-decoded.  The 2026-08-05 banners calling the feeder dark
were an export-gap-blind grep (named members, not offsets).  Fixes:
mechmppr publishes the chain MAX into mech->myomerEffectiveness (the
binary's +0x79C home) so the crouch posture gate reads the live factor
(dead/overheated myomers now genuinely refuse squat/rise -- previously the
gate read a neutral 1.0 and never fired); the duplicate speedDemand multiply
in the posture block is removed (mechmppr's is the one application); banners
and locomotion.md corrected.  Squat re-benched green on the live wiring.

Joe DiPrimaandClaude Fable 5 591d205b19 CROUCH complete: full cycle + MP replication verified 
The WIP's 'pose does not hold' was a chain of bench-instrument errors, not a
code bug: every capture ran in COCKPIT view (the pilot cannot see their own
legs; the eye-height residual masked as reversion).  Joint probes prove the
park holds indefinitely (knee 1.138, root -2.219 steady); the 2-node bench
shows the observer's replicant fully crouched and held (duckmpA_031 -- the
type-3 state record carries it with zero new replication code); the second
scripted press (new BT_BTNTEST2 env) verifies RISE -> standing zeros.
MP button delivery confirmed mode-mask-clean (the one miss was round-start
jitter).  Diags added, all BT_DUCK_LOG-gated: SetLegAnimation re-arm tracer,
1 Hz joint probe, RIO press mode-mask, BT_TREE_LOG topology dump, and the
squat-park log.  RESIDUAL filed: pilot's own cockpit eye does not ride the
root drop (DPLEyeRenderable chain composition; cosmetic).

Joe DiPrimaandClaude Fable 5 dd70061e0e CROUCH reconstruction (WIP): the master posture/duck machine, decoded + wired 
Raw-disasm of the dark master-perf region (@0x4a9cf0-0x4aa0af): the myomer
effectiveness factor (+0x79c, MAX over heatables' +0x31c, scales speedDemand
-- feeder @004b8be3 unreconstructed, neutral 1.0 [T3]), the posture selector
(+0x3f8: mode/novice/leg-state/myomer gates -- novices cannot crouch), and
the DuckRequest consumer (standing -> SetLegAnimation(2) 'sqd', ducked ->
SetLegAnimation(3) 'squ', ForceUpdate 8+1 ships the type-3 state record,
stability alarm flips, request consumed).  +0x1DC = mountSegment... er, the
searchlight learned that one; here: mapPosture @0x3f8 + myomerEffectiveness
@0x79c members land; value-space note (port normal mode == 1, binary 0).

VERIFIED: request->consumer chain fires ([duck] SQUAT), the sqd clip plays
(22kf/7joint, ends root -2.22 crouched -- clip data parsed from BTL4.RES,
squ is its exact mirror; loader slot map re-verified byte-exact).  OPEN: the
parked crouch pose does not HOLD on screen (reverts ~1 frame after clip end
with NO SetLegAnimation re-arm logged) -- the hold's render path is the
remaining dig; [duck] re-arm tracer left in SetLegAnimation.

Joe DiPrimaandClaude Fable 5 b75bb4a04c Searchlight beam: the btfx brighten material class + BT_SPOT_SELF rig 
SPOT.BGF decoded: a 7-vert cone from the mount, ~50u forward and ~35deg DOWN
(a ground-pool lamp, not an air beam), verts tinted cyan-white, material
class 'brighten' smuggling its additive factor in DIFFUSE.r (0.25) with a
warm emissive on the night page.  The loader had never met the class -- it
drew as an opaque dark-red blob.  Now: brightenFactor parsed (name-gated to
brighten*), batch -> L4DRAWOP.brightenAlpha, drawn in the blend pass as an
additive veil (dest += vertexRGB x factor), unlit.  [T3] tint compose
(vertex cyan vs night emissive warm) noted in the draw branch -- field
eyeball accepted the current look.

BT_SPOT_SELF=1 (bench-only): builds the cone on the own-cockpit tree so the
BT_CAM=face view can inspect it solo.  KB: view toggle is BACKTICK ('V' is
the rear-view hold since #68 -- the toggle skips bound keys); stale V-toggle

Joe DiPrimaandClaude Fable 5 412053d5af Searchlight reconstruction -- the pod's night kit, both halves 
The subsystem (sim/toggle/attribute/replication) was already complete; this
lands the missing VISUALS, decoded from MakeMechRenderables @004cef28 case
0xbd8 (raw pseudocode part_014):

- COCKPIT: the 1995 searchlight is a FOG SWAP -- the @00456778/@00456814
  watcher switches DPLRenderer::SetFogStyle between the authored fog= (lit)
  and nosearchlightfog= (dark) sets per map/time page in BTDPL.INI.  The
  engine kept the whole system under its real names; completed the stubbed
  plane application (currentFogNear/Far) and transcribed the watcher (with
  its inverted-cache seed) into TickSearchlight.  CONSEQUENCE: night now
  STARTS on the authentic dark set (near-plane 5u on arena pages) -- our
  builds had rendered the searchlight-ON fog permanently.
- EXTERNAL: spot.bgf beam cone hung on the searchlight SITE joint, shown/
  hidden from the replicated LightOn attribute (@0045612c watcher).  Site
  segments now build geometry-less DCS children (posed + parentable, as the
  1995 graph did) -- previously they were skipped entirely.
- searchlight.hpp: commandedOn @0x1DC identified as mountSegment (resource
  segmentIndex; the cone's mount joint).

Benches: searchfog.sh (solo cockpit: first-tick dark sync, F5/0x14 press ->
SetFogStyle(2), red-fog probe end-to-end), spotcone.sh (2-node: B's button ->
lightState replication -> A logs "[spot] cone SHOWN (seg 20)").  Cone look
(size/aim on the mount) pending an eyeball pass.

Joe DiPrimaandClaude Fable 5 91bd28669e #45/#134 authentic score/death report tail -- replaces the scoring stand-ins 
Reconstructs the dark-gap tail of Mech::TakeDamageMessageHandler
(@0x4a02f4-0x4a0890, raw disasm): the three id-0x16 score reports (kill to
the shooter's player / type-0 wire-fidelity / received to the victim's
player) and the BT 0x38-byte VehicleDeadMessage extension {killed-by player,
kill zone} dispatched from the death tail.  Retires BTPostDamageScore /
BTPostKillScore and the per-hit inflicted credit (never existed in 1995:
@0x4c0200 is bound in no handler-table entry -- byte-scan receipt in
decomp-reference).  Suicides now dispatch and the handler negates the award
(the #134 panic penalty).  Collision divert falls through to the death tail
per @0x4a0375 (wall deaths respawn + blast; no score).  ScoreMessage fields
renamed to decoded truth (vitalHit/zoneIndex/subsysID) + wire asserts;

The missing half of Advanced Damage, found by call-scanning
Explosion::SplashDamage @0042fad0: TWO callers, not one -- Missile::Perform
(the known #62 path) and 0x4a0bda, the UN-EXPORTED tail of
Mech::TakeDamageMessageHandler itself.  Raw disasm @0x4a07b8-0x4a0bda:
when the victim ENTERS dead(9)/eject(10) during the applications, the
binary sets the wreck burning (id 0x17, deferred -- handler not yet
reconstructed), spawns the death Explosion (model 0x31 -- our death-list
visuals stand in), and SPLASHES:
  gates : owning player's advancedDamageOn (+0x264) AND NOT
          suppressConsole (+0x258 -- eject sets it: PUNCH-OUTS NEVER
          BLAST, the authentic anti-suicide-bomb rule)
  damage: type 2 Explosive, amount = deathSplashDamage (mech+0x520),
          bursts = round(0.001 * moverMass * 15.0) -- scales with tonnage
  radius: deathSplashRadius (mech+0x524); per-victim falloff
          bursts/dist^1.25 in the shared core
Draco's collision-divert suspicion is settled: the blast is TYPE 2, the
divert never touched it -- the tail was simply never reconstructed.

Port: deathSplashDamage/Radius PROMOTED from the Wword scratch bank to
named Mech members (the bank is one GLOBAL array -- authored per-chassis
values were clobbered to the last-loaded mech); BTSplashCore split out of
the #62 weapon splash and shared; BTApplyDeathSplash + the death-edge arm
in the handler tail; BTPlayerConsoleSuppressed bridge (friend).

Bench (2-node, B parked 8.9u from a self-destructing A): blast fired with
authored madcat data (radius=50, amount=5, mass=75000 -> 1125 base
bursts), B took 73 bursts (falloff exact: 1125/8.91^1.25), cross-pod
delivery + cylinder spray verified on B's own log ([dmghit] type=2
burst=73 across zones).  ~365 damage at 9u -- Draco's 'double kills on

Joe DiPrimaandClaude Fable 5 6dd1212e0c #52 campaign close: full transition matrix PASSES at 2 nodes -- field instrument rides 
Provocations run under the verified [skate] detector: sustained healthy
walking, 7x respawn-while-moving, gimp onset at speed, ~21s of sustained
GIMPED walking (aimed-leg self-damage: BT_SELF_DAMAGE_ZONE=dz_ldleg),
leg-destruction death (authentic: lvl 1.0 -> leg gone -> fall/death; the
mid-session "died of the gimp edge" reading was a capped-print artifact,
retracted), and respawn.  ZERO skate anywhere.  Peer gimp replication
VERIFIED live: observer reads gl=3 + sim=3 with the gimp bodyStates
cycling for the whole master limp window (#82 remains fixed).  Conclusion:
the field skating does not reproduce at lab scale; the detector + SKATE
matchlog record ship with the next cut and the field names the failing
case.  Bench scripts archived (skatebench3-7; 7 is the clean-room one --
the sed-derived chains dropped envs twice).

Also: BT_LAMP_LOG=1 joins the field bats (#135 -- lamp/annunciator edge

Joe DiPrimaandClaude Fable 5 9604f4c492 #52 SKATE detector (ungated field forensic) -- negative-verified; local repro eludes 
The night-12 field logs eliminated record starvation (zero [ghost] during
three observed skating windows), so the bug lives in gait APPLICATION on
peers.  This adds the [skate] detector to the death-handler tick: a
replicant moving >0.08 u/frame for 90+ frames with BOTH animation
channels idle (legCycleSpeed + bodyCycleSpeed ~ 0) logs one line per
episode + a SKATE matchlog record carrying the discriminating inputs
(legCyc/bodyCyc/cmdSpd/destroyed/mode).

Honest history: the first build keyed on legCycleSpeed alone and
false-fired on every healthy movement phase -- the current peer
architecture poses joints from the BODY channel (s_peerLegCh=0,
AdvanceBodyAnimation mj=1), so legCycleSpeed==0 is NORMAL there.  Caught
same-session by the [gimpfeed] silence (AdvanceLegAnimation never runs
on peers); corrected to channel-agnostic before anything shipped.

Bench (skatebench2.sh, 2-node, autodrive walker + kill every ~40s):
7 death/respawn cycles, ZERO skate hits either side -- no false fires,
and light local conditions do NOT reproduce the field skating.  Next
provocations: leg-GIMPED walker (the #82 family transition) and 6-player
load; otherwise the detector rides the next cut and the field names the
failing case for us.

Joe DiPrima 754518b587 handoff: #131 fixed with receipts + build ritual note 2026-08-05 11:13:17 -05:00
Joe DiPrimaandClaude Fable 5 546aabd5ba #131 false lock FIXED: miss-means-miss -- the pick answers only for drawn geometry 
Night-12 field report (Ronin/Conn Man/Oracle, blackhawk-correlated): lock
ring lit with the reticle visibly off the mech + no-reg complaints.  Root
cause: TWO port stand-ins answered where the 1995 card (which cast against
the DRAWN geometry) would miss -- the pick's any-object sphere fallback and
the caller's whole-mech AABB fallback.  The regime that exposes them: a
LEVEL boresight over a SHORT mech -- the blackhawk's mesh tops out below
eye-ray height, so the ray clears every triangle but pierces the fat cull
spheres; the ring lights with the reticle above the mech's head (the
operator watched exactly this on the sweep bench).  Careful aimed-down fire
rides triangles, which is why Oracle's per-panel audit passed on the same
build.

Fix: MechSegmentPick returns 1=drawn-geometry hit / 0=TRUE MISS / -1=no
render tree; the sphere may answer ONLY for a mesh the reader cannot parse
(pm==0 -- currently none exist: counters objs/invFail/noTri all clean);
the AABB survives ONLY as the pre-tree replicant grace.  A readable mesh
the ray misses is a MISS -- no lock.

Verified (2-node vs bhk1 at 100u, all runs on force-relinked string-
verified exes after today's stale-link flake):
- LEVEL lock-sweep: 0 locks all run (pre-fix: lock band from 168 sphere
  answers; picksrc tri=0 sphereFB=168).
- DOWN-PITCHED sweep: locks return 100%% tri-sourced (tri=158 sphereFB=0),
  landing on real parts (rarm/ldleg/rdleg) with honest gaps.
- Full zone-walk matrix: tri=18874 sphereFB=0 box=0; victim took 156 hits
  across 16 zones incl. both side torsos -- combat un-regressed.

New instruments (all env-gated): BT_LOCK_SWEEP=<axis> torso pan (the
operator-visible lock-envelope bench), [locksweep] transition log,
BT_LOCK_ENVELOPE synthetic unit-sweep probe, [picksrc]/[pickbox] source
telemetry with objs/invFail/noTri localization counters.
Bench: scratchpad/night12/zonewalk_bhk.sh.

NOTE for the field: locking is now strictly TIGHTER (ring = reticle truly
on the machine).  If era testers feel the pods were more forgiving,
Draco's "slight lock linger" memory becomes a deliberate investigation
(sourced hysteresis), not an accidental sphere halo.

CydandClaude Opus 4.8 67074c80e2 Plasma window joins the glass_layout.cfg no-frame list 
The desktop plasma window (L4PLASMAWIN, "BattleTech - Plasma") is created by a
different TU than the per-display panels, so it couldn't be a gWins[] entry and
sat outside the sticky-layout / ,noframe system.  Add a tiny extern-window
registry to L4GLASSWIN so it rides the same glass_layout.cfg:

  - BTGlassLayout_QueryWindow(title, rect, noframe) -- read a title's saved rect
    and ,noframe flag (used by the plasma on creation, BEFORE sizing, since
    WS_POPUP's frame extent differs from the framed tool window).
  - BTGlassLayout_RegisterExtern(hwnd, title) -- register an externally-created
    window so SaveLayout writes its line (with a last-known-rect cache so a
    teardown before the save still preserves the line).
  - BTGlassLayout_Save() -- public save trigger the plasma WndProc calls on
    WM_EXITSIZEMOVE / teardown.

L4PLASMAWIN now reads its saved rect+flag on create (WS_POPUP when ,noframe,
position restored), registers itself, and saves on finished-drag/teardown.  All
BT_GLASS-gated; the pod is untouched.  The plasma blits directly every frame, so
it has no WM_TIMER focus-throttle.

Verified: Release links clean; drag wrote "BattleTech - Plasma=321,222,528,167",
reload with ,noframe brought it up WS_POPUP (WS_CAPTION absent) at 321,222.

CydandClaude Opus 4.8 7d112ce309 Glass panels: flash at full rate when unfocused + red Panic/Eject button 
Two glass-panel indicator fixes reported by playtesters.

1. FLASH SLOW UNLESS FOCUSED.  The per-display panel windows repaint off a
   62ms WM_TIMER, and Windows coalesces/throttles timer + paint messages for a
   window that is in the BACKGROUND (unfocused) -- so with the game window
   holding focus the panels' lamp flash (a repaint-driven animation) crawled,
   and giving a panel focus un-throttled it.  (My earlier surround fix drew in
   the main D3D frame and never touched these separate windows.)  New
   BTGlassPanels_Tick(), called once per frame from the main render loop
   (L4VIDEO), drives a synchronous InvalidateRect+UpdateWindow at the ~16Hz
   flash cadence -- the main loop runs every frame regardless of which window
   has focus, and the forced paint bypasses the throttled timer-message path.
   The WM_TIMER stays for its one-shot re-snap.

2. RED PANIC/EJECT.  0x3D is the Panic/Eject button; on the blue flight panel
   it was just another blue block.  The shared flight-grid geometry (L4RIOBANK)
   now tags 0x3D as colorClass 0 (red); L4GLASSWIN's AdoptBank maps colorClass
   0 -> ClrRed explicitly (the flight bank's ClrBlue default no longer swallows
   it), and the surround (L4VB16) already renders non-blue/yellow as red -- so
   the eject stands out red in both the surround and the exploded window.

Verified: Release links clean (40 tolerated /FORCE externals only); exploded
panels boot + run 13s no crash under the per-frame repaint pump; riobank dump
confirms 0x3d class=0 (red), neighbours class=2 (blue).

Joe DiPrima 8b887f6cec handoff: #124 per-panel correction 2026-08-04 17:58:09 -05:00
Joe DiPrimaandClaude Fable 5 1d3616cceb #124 CORRECTION: aimed hull hits resolve the struck dz_* PANEL -- players were right 
The 08-03 zone rule (struck SEGMENT's SKL dzone, ALWAYS -> every aimed
torso hit = center torso) was wrong, and era players' pushback caught it.
Byte-level proof: MAD_TOR.BGF zone-tags the hull PER PANEL (dz_utorso x36,
dz_ltorso/rtorso x18, dz_dtorso x16, all four rear panels, searchlight);
the dpl hit result kept GEOGROUP granularity (dplHitGeoGroup, T0); and the
binary's segment->zone map @49db20 has NO runtime caller (raw call-scan:
sole caller = CreateStreamedDamageZone, load time) -- no segment-level
collapse mechanism exists.  Oracle's night-10 'only LCT gets hits' audit
was the BUG's fingerprint, not the pod's design.

Fix: MechSegmentPick attributes the struck triangle to its draw op (index
range) and takes the op's .DZM-bound zone -- the #87 armour-darkening
bindings, the same authored patch->zone mapping that already paints the
panels -- with the segment dzone as the untagged fallback.  ZoneAimPoint
now aims hull zones at their patch CENTROIDS (all hull zones previously
shared the chest cull-center), which also upgrades the zone walker.

Bench (2-node zone-walk vs spinning madcat, zonewalk_madcat.sh): every
hull panel resolves individually -- utorso 11/12 in-zone, no L/R
mirroring, all four rear panels register; misses are the panel facing the
shooter mid-spin (correct geometry, not misattribution).  Victim applied
254 hits spread across every panel family.  Was 102/102 hull aims ->
dtorso before the fix.

The night-11 instrumentation that makes the next ghost/K-D report
diagnosable instead of anecdotal:
- UNGATED [ghost] stale-replicant detector: ReadUpdateRecord stamps every
  applied record; the death-handler tick logs ONE line per starvation
  episode (>600 frames, unburied) with entity id + mode + last position,
  plus a GHOST matchlog record.  Verified both ways: zero false positives
  on a healthy 2-node session; fires on both nodes at frame 601 after a
  mid-session relay kill.
- Entity IDs on the render forensics (MakeMechRenderables / RemakeEntity /
  wreck-swap fallbacks) and the replicant un-wreck line un-gated -- ghost
  triage no longer needs players to set envs.
- players/*.bat (steam + both joins): BT_MATCHLOG/BT_SCORE_LOG/BT_DEATH_LOG
  on for every field session.

Joe DiPrimaandClaude Fable 5 26ab2fee3a Respawn-reset audit: valve restore + peer smoke cleanup (both binary-grounded) 
Operator reports audited vs the binary (full matrix in RESPAWN_REARM_PLAN
addendum):
- VALVES (real gap): Condenser reset @004ae534 was missing from the decomp
  export -- raw disasm shows it chains HEATSINK (coolant refill runs; the
  old body chained HeatableSubsystem per the stale TCP shard) then, respawn-
  side, resets valveState to detent 1 and restores massScale from
  refrigerationFactor.  Mech::Reset now also runs the binary's tail call
  (@0049f788 BTRecomputeCondenserValves) so flow fractions rebuild from the
  reset detents.  Bench: detent 5 -> death -> "[respawn] Condenser1 valve
  detent 5 -> 1".
- #129 SMOKE (real gap, peers-only): the replicant un-wreck edge rebuilt
  the model without the @004d0c14 per-entity effect cleanup, so the
  observer's last 10s wreck-plume window rode the teleport onto the fresh
  mech.  BTStopEntityPfx now runs on the edge; bench shows no plume line
  after any un-wreck until the next death.
- AUTHENTIC (no fix): weapon->generator taps persist (@004b0e6c only
  resolves the link) and MFD display/control modes persist (mapper vtables
  0050f45c/0051e440 slots 8-11 = plain root bodies, read from the exe).

Joe DiPrimaandClaude Fable 5 1f995ee35a #124 twist-sign VERIFIED correct (live missile bench) + the rig to do it 
The frame-adapter's inferred twist-sign flip (SelectSlice theta -= twist,
vs the binary's += pre-reflection) was the last unverified half of #124 --
every earlier probe ran at twist 0.  Bench: stationary madcat target with
the torso PINNED at 0 / +140 / -140 deg, LRM salvos from a fixed shooter
(missiles = the authentic cylinder path; the binary DROPPED zone -1 beam
damage).  Result: slice picks track the physically-facing flank in BOTH
directions (twist-left -> right-family zones for left-flank impacts,
twist-right -> left-family), deterministic, wrong-sign outcome (slice 7
vs observed slice 1) clearly excluded.  No game-code change needed.

Instrumentation added (all env-gated):
- torso.cpp BT_FORCE_TWIST=<-1..1>: HOLD the sim's analogTwistAxis (the
  input-level pin was dead -- live input rides the CONTROLS.MAP device
  push, and Basic mode auto-centers; sim-level is plumbing-independent).
- dmgtable.cpp [slice] line: rot flag, live twist, thetaIn/thetaAdj,
  chosen slice -- the weighted leaf roll made zone-only logs ambiguous.
- [dmgresolve] now names the zone (BTMechZoneSegAndName).
- mech4.cpp BT_FORCE_TWIST input pin + one-shot mode cycle (kept as doc
  of the dead path), mechmppr [mppr] mode probe.
- scratchpad/night11/twistsign.sh: the 3-config bench.

Joe DiPrimaandClaude Fable 5 6180a44c64 #91 thor black rectangle: it's the OWN missile pod -- blakskn now material-keyed 
Three testers reported a black rectangle swaying with the footsteps in the
thor cockpit (Summoner = the thr1 label, same THX canopy -- no isolation).
Decode: the inside view is a PER-MECH AUTHORED type-A set, not the cop
alone (no fallback in EntitySegment::GetVideoObjectName -- authored data):
madcat/vulture/bhk1 = cop; sunder/loki/avatar = +tor; thor = +tor +MSL
(the shoulder pod, the reported rectangle); owens = +both legs +tshd.
The pod/leg pilot-facing surfaces use the SAME "<pfx>skin:blakskn_dz_*"
interior-structure material as the canopy frame, but the unlit frame
constant was keyed on the _cop FILENAME -- identical material rendered
(0.13,0.12,0.15) on the canopy and pure (0,0,0) on the pod/legs
([matlog]: owx_cop blakskn vcol=FF211F26 vs owx_lule vcol=FF000000).

Fix (bgfload.cpp): the frame-constant treatment keys on meshIsCop OR
material contains "skin:blakskn_dz_". mechfx:blakskn_mtl (tshd shadow
quads) deliberately excluded. Verified: zero pure-black px in the lower
view band across walk captures, the pod plate renders frame-toned and
blends with the bar at rest (the reported anomaly dissolves), owens legs
read as coherent structure, canopy/terrain un-regressed.

Diags added: BT_MAT_LOG=<stem> per-batch material routing dump (bgfload),
BT_HIDE_INSIDE_SEG=<substr> inside-mesh hide (btl4vid), [view] per-segment

Joe DiPrimaandClaude Fable 5 648f6b1675 Steam gate: rejected players now get a MESSAGE BOX, not a silent quit 
A failed join returns 1 to the FE, which QUITS the exe -- so every
rejection so far was a log line plus "the game just closed" (#68's exact
complaint). New LobbyNotice() = same text in the day log (flattened, still
greppable) + blocking MessageBox. Wired to every join-side bail:

- BUILD MISMATCH: when the version-filtered search is empty, probe once
  without the version filter; if a lobby IS up, the box names the host's
  build vs ours (lobby data rides the list result -- no join needed).
  Post-entry verify mismatch gets the same box.
- NO LOBBY FOUND: probe empty too -> plain no-lobby box naming our build.
- STEAM UNAVAILABLE: transport install failed.
- LEFT BEHIND: host launched without us (no token in btl4map).

Old exes still exit silently on rejection -- nothing shipped today can
add text to a binary players already have; the host's roster marker +
REJECT log line remain the operator's view of those.

Joe DiPrimaandClaude Fable 5 d050db5cae Steam BUILD GATE, host half: reject OLD exes at GO (the real Conn Man case) 
The joiner-side filter only runs on builds that HAVE it -- a stale-zip
player runs an old exe with no filter, finds the lobby, and joins anyway.
The host must do the rejecting, and the lever already ships in every old
build: a member omitted from btl4map hits its own "the host's map is
missing us" path and fails the join cleanly.

1. PublishSelf stamps per-member data bv=BT_VERSION_STRING; an old exe
   cannot fake a key it never sets.
2. Host GO mint: any non-self member with absent/mismatched bv gets NO
   token -- omitted from the map, loud REJECT LobbyLog with both builds.
3. Room screen: mismatched members show [WRONG BUILD -- WILL NOT LAUNCH]
   so the host sees who's stale BEFORE pressing GO, not after the match
   starts short-handed.

Verified in the deployed exe by string scan (btl4ver, REJECT-at-GO,
BUILD MISMATCH ascii + WRONG BUILD utf16 all present). Field behavior to
verify on the next Steam night.

Mixed-build lobbies silently corrupt raw-struct replication (night-9: one
stale-zip player, one desynced stream, ghost mechs + K/D doubt). Three
additive edits in btl4lobby.cpp:

1. HOST stamps the lobby with its exact build (btl4ver = BT_VERSION_STRING).
2. JOINER's lobby search filters on build equality -- a stale-zip player
   simply finds no lobby, and the "no lobby found" log line NAMES the local
   build so the report is self-diagnosing (#68's silent-exit lesson).
3. Post-entry verify (covers invites/direct joins + unstamped older hosts):
   mismatch -> log both versions loudly, LeaveLobby, fail the join.

LAN/relay (join.bat) handshake remains a separate 717 item -- this covers
the Steam path the operator asked about.

Deterministic leak bench (BT_KILL_SUBSYS partial form, "Condenser4=0.5":
zone level without the crit -- a clean leak source) + the aud-tail receipts
decode the voice stutter end to end: the warning is a phrase-sequenced
voice patch (Warnings01 zones as notes), and every techstat leak-bit edge
restarts/stops the sequence mid-phrase (authored zero-release = hard cut).
At a drained tank the draw HUNTS the authored 0.0025/0.003 band -> edge
streams -> progressive clipping as more systems hunt.

The anti-spam wooHoo latch would bound exactly this -- but no armer exists
anywhere in the flat export, and the authored tuning is minDur=0 range=0
chance=0 (dumped live): DORMANT BY AUTHORING. The clipping is the 1995
experience; the port's one real bug here was the 2x hunt cadence, already
fixed by the 28 Hz filter (#119, 1df2c57). No code change warranted.

Bench additions: the partial-damage killsub form + the authored-tuning

CydandClaude Opus 4.8 f99003cf50 Glass cockpit lamps: sweep every frame so lit buttons track the sim under load 
Playtesters (all on the glass surround) reported the cockpit lighting
sometimes going slow or nonexistent while the 3D view stayed perfectly
smooth.  The RIO serial/lamp stack is byte-identical to pod-proven Red
Planet (diffed L4LAMP/L4RIO/L4SERIAL), so the wiring was fine -- the defect
is the glass UPDATE CADENCE:

The lit buttons draw every frame (BTDrawCockpitPanels, reading
PadRIO::GetLampState), but the lamp STATE sweep that fills that store
(LampManager::Update -> AssertNewLampValue -> SetLamp) rides the gauge
renderer's FOREGROUND turn, which fires only once per full gauge cycle
(foreground->background->copy).  The cycle can't reach the next foreground
turn until the throttled background gauge sweep drains the ~140-instrument
active list -- and that background task starves under MP load (issue #45,
"instruments freeze while fps stays healthy").  So the lamp sweep ran
~1x/second: buttons froze / flashes stalled while the view (a separate
per-frame foreground render) stayed smooth.

Fix: BTGlassSweepLamps() runs the lamp sweep EVERY frame on the dev/glass
composite path (L4VB16.cpp, in BTDrawGaugeInset), decoupled from the gauge
cycle.  It is cheap -- deduped state pushes over ~72 lamps, no raster.  The
pod never enters BTDrawGaugeInset (real gauge hardware), so its authentic
bandwidth-paced serial lamp cadence is untouched.  BT_GLASS_LAMP_SWEEP=0
restores the authentic once-per-cycle behaviour.

Verified: Release links clean (only the 40 tolerated /FORCE externals);
glass surround boots and runs, lamp sweep pushes state (43 [lamp] pushes,
buttons lit), ~60 fps, no crash.  The under-load win is structural (the
sweep is now an unconditional per-frame call); true MP-starvation repro
needs multiple nodes.

Joe DiPrimaandClaude Fable 5 a728fa6de9 #118 alarm dig complete: the TechStatus bit model -- MarkGeneratorOut bridge removed 
The gauge-alarm "condition" is a STATUS-FLAG BIT INDEX edge-scanned by
MechTech (bit 0/1 structure, 2 leak, 3 heat, 4 AmmoBurning, 5 Jammed,
6 !HasVoltage). Conditions 4/5 -> the engEject flash = the AMMO purge/unjam
invite (flashing the very key whose streamed function is EjectAmmo) --
never pilot eject; cond 6 -> the bus-switch invite; the PANIC lamp is the
sole pilot-eject indicator.

The destruction->stateAlarm(4) bridge is REMOVED as unfounded: alarms never
read stateAlarm; state 4 is the THERMAL BREAKER state produced by
GeneratorSimulation itself (byte-matched vs FUN_004b1f7c). And the binary's
crit distributor (@0049c9a8, read raw) touches nothing electrical -- a
generator destroyed in place keeps stale Ready voltage until any transition
recomputes output via (1 - damage) x rated. The port now matches that
subtlety exactly (verified: single-gen force-kill -> no bus invite, no arm,
silent unarmed keypad -- all authentic).

KB: the full bit table + invite semantics + electrical subtlety recorded in
decomp-reference.

Joe DiPrimaandClaude Fable 5 609dde8051 #118 strict: REMOVE the coolant-clause hysteresis -- the flap is authentic 
The operator's causality challenge held up: the hysteresis did NOT fix the
audio tick (the tick persisted past it and was the autofire scalpel's
20/sec jam clicks -- no game bug; control run without autofire is clean).
With the dead-code claim corrected, the boundary flap is AUTHENTIC: the
arcade evaluated the identical plain < 0.05 compare per frame, so a pod
hovering at the line flapped the same way -- cosmetic mode/lamp churn,
crash-free across hundreds of bench transitions. Deviation unjustified;
the binary's compare is restored.

Verified on the reverted build: armed PANIC press -> PUNCH-OUT (1); audio
profile clean (sparse explosions/warnings only).

Eject deviation ledger now: ONE item -- the Panic-button->pilot-keypad
desktop wire (hardware emulation, not behavior).

Joe DiPrimaandClaude Fable 5 d86b65d7aa #118 STRICT: remove the eng-page eject-key hook -- soft keys never pilot-eject 
Operator called binary-faithful; the trace agrees. The hook (bfc072b/
fa3d634) fired ALONGSIDE the key's authored per-page function, so on a
weapon eng page an armed pilot pressing UNJAM/EJECT to clear a jam would
self-destruct -- a destructive hijack of a real control. Removed; the
authored press model stands alone: pilot KEYPAD bank (desktop numpad) or
the PANIC key while armed. The flashing engEject cell is the invite lamp.

Regressions: armed PANIC press -> PUNCH-OUT (1); armed soft-key 0x0B press
-> no eject (0); streamed ammo-eject route untouched (the hook was purely
additive).

Remaining marked deviations, both flagged in code and handoff: the coolant
arm hysteresis (0.05/0.06) and the Panic-button->keypad desktop wire (the
pod's physical matrix emulated).

Joe DiPrimaandClaude Fable 5 675fe68cb0 #118 correction sweep: the ARCADE's eject was LIVE -- 'dead code in 4.10' was wrong 
The absolute-pointer scan missed the E8-relative call; the later byte-scan
found it (FUN_004a9b5c+0x10 -- the master performance evaluates eject
permission per frame in the shipped binary). Under deadline pressure the
disproven 'unfinished/dead code' claim leaked back into three comments and
the handoff; swept per the correction mandate.

Settled press model, now stated correctly everywhere: pilot eject = the
pilot KEYPAD bank while armed (+ the PANIC key reporting through that
matrix). The MFD soft keys NEVER pilot-eject in the binary -- every page
routes them to authored functions; the flashing engEject cell is the
INVITE LAMP. The port's page-gated eng-key eject is a MARKED CONVENIENCE
deviation (operator-requested), and the coolant hysteresis is a MARKED
smoothing deviation for a degenerate boundary oscillation -- not
completions of unfinished code.

Joe DiPrimaandClaude Fable 5 38872ac726 #118: coolant-clause hysteresis kills the panic-arm flap (10 Hz mode churn) 
Post-respawn under sustained fire the bank fraction hovers at the 0.05 arm
threshold and the plain compare flipped ejectPermitted EVERY FRAME --
hundreds of mode ON/off pairs churning the mask, the lamp, and the arm cue.
The evaluator was dead code in shipped 4.10, so the boundary flap is a
first-ever-exercised condition; completed with the engine's own idiom
(HeatSink coolantActive dual thresholds): ARM below 0.05 (the binary
constant), release above 0.06, no new members.  Stress bench: 1 arm
transition in 3 minutes (was: hundreds).

NOTE: the operator's ticking SOUND persists past this fix -- it is the
separate, pre-existing night-10 "audio stutter on coolant leak" family;
hunt continues at the audio-cue chokepoint.

Joe DiPrimaandClaude Fable 5 5a4ee55e4e #118: the eject slot graphic returns -- vtbl+0x58 is DrawBitMapOpaque [T0] 
The proper RE the corruption arc demanded: counting GRAPH2D.h's declared
virtual order, GraphicsView vtbl+0x18 = SetColor and +0x24 = MoveToAbsolute
land exactly -- and +0x58 is NOT DrawBitMap (+0x54) but the NEXT virtual,
DrawBitMapOpaque(background, rotation, bmp, sx1, sy1, sx2, sy2).  The wipe
is a two-span OPAQUE draw with INVERTED fg/bg pairs -- the literal "inverse
wipe" -- and FUN_004c5fb8 transcribes byte-exactly with the real signature
(the ++level between spans is inclusive-bounds bookkeeping, no gap).  The
base ctor fields were already right (colors +0x94/+0x98, bitmap Size.x/y at
+0x9C/+0xA0, decomp @004c5e84).

BallisticWeaponCluster::ejectWipe re-wired (bteejtm.pcc <- PercentOfEject).
Stress-verified: 4 gens dead + autofire jams + leak warning, weapon pages
pristine end to end.

Joe DiPrimaandClaude Fable 5 78722542fd #118: REMOVE the full-face flash overlays -- the MFD corruption, root-caused 
The operator's three captures decode as ONE mistake drawn two ways: the
cockpit compositor deliberately draws the side buttons as BIG rects tucked
UNDER the display surfaces (step 2), with only the protruding edge visible
-- the edge IS the port's lamp light (the pod's backlit keys sat beside the
CRT; there is no in-display face to light).  My on-top "flash overlay"
(86a6bbb L4VB16, 5f79dce L4GLASSWIN) violated that design: drawn after
DrawDevSurface without resetting the bound texture state it rendered the
gauge atlas as green striped garbage at the button rects; with the state
reset it drew honest full faces -- solid flashing red covering that whole
portion of the MFD.  Both overlays removed; the original step-2 rendering
(which already tick-animates lamp shades) is the whole story.

Pixel-verified through the full stress (4 gens dead, autofire jams, leak
warning): weapon pages pristine end to end, and the 0x27 edge lamp
square-waves 34.0 <-> 28.9 across consecutive captures -- the invite
flashes at its authentic scale.

(The eject-wipe gauge -- the OTHER corrupting draw, visible in the earliest
sighting -- stays re-stubbed pending a real RE of FUN_004c5fb8's draw op.)

The BitMapInverseWipeScalar Execute passed the colour constants as
DrawBitMap's first argument; the sibling wipe always passes 0 there (colour
selection is SetColor only). The nonzero arg smeared striped garbage across
the weapon MFD pages from the gauge's first draw (operator's capture.png).
Pixel-verified clean after the fix (weapon pages pristine, eject graphic

Joe DiPrimaandClaude Fable 5 86a6bbb9cb #118: the flash overlay lands in the REAL compositor (L4VB16) + [ckflash] probe 
The first visibility fix painted L4GLASSWIN -- a window the operator's
single-window layout never shows. The main-window cockpit compositor is
BTDrawCockpitPanels (L4VB16): same under-the-surface masking, so the RIO
flash was again invisible. The 3b overlay now re-draws flashing lamps
(state & 3) above the surfaces there, tick-phased; [ckflash] (BT_LAMP_LOG)
logs each animated draw. Verified in-engine: addr 0x27 state 0x37
alternating shade 1 -> 3.

The glass windows paint buttons UNDER the display surface (only a sliver of
edge protrudes), so the RIO flash commands were arriving ([lamp] 0xb <- 0x37
FLASHING in every trace) while the operator "never saw it flash" -- the
blink was a few masked pixels.  Lamps carrying RIO flash bits (state & 3)
now re-draw their full face above the surface with the tick-phased shade:
the gotoEngineering / engEject invites read like the pod's backlit keys.

Joe DiPrimaandClaude Fable 5 fa3d634ed3 #118 crash fix: the eng-eject page gate moves into the game-thread RIO drain 
The page-gated eject query ran in the window-click thread (PadRIO
EmitButton) and dereferenced the TU-local application global -- NULL there
under the /FORCE duplicate-symbol layout -> c0000005 at mode-manager +0x50
the moment the operator pressed the eng eject key (field crash,
live.log [crash] record). Moved into LBE4ControlsManager::ProcessRIOEvent's
ButtonPressedEvent branch, where mode_mask is already resolved on the game
thread; PadRIO now only queues events. Same gate semantics (armed + that
bank's ENG-page mode bits); verified no-crash + no-eject on the quad page.

Joe DiPrimaandClaude Fable 5 bfc072b56f #118: the ENG-PAGE EJECT KEY ejects -- page-gated intent completion 
The decode that settles it: the eng-page side-key functions align key-for-
key with the engEject lamp map (selectGenA-D = 0xF-0xC, EJECT = 0x0B,
GEN-MODE = 0xA, COOLING = 0x9, BACK = 0x8; banks 2/3 at 0x27-/0x7-), and
the streamed weapon pages route the same key to EjectAmmo -- so 0x0B/0x23/
0x03 ARE the authored EJECT position. On generator pages the shipped
stream leaves the key with NO live route (msg 9, no handler anywhere):
eject was UNFINISHED in 4.10 (the evaluator was dead code -- the arcade
never armed panic at all). Intent-completion [T3, marked]: while PANIC is
armed AND that bank displays an ENGINEERING page (kBTEngModeMask bits --
the same gating the alarm lamps use), the flashing EJECT key fires the
pilot-keypad eject. Any other page: authored function untouched (the two
field regressions came from skipping the page gate).

Verified: armed + QUAD page + 0x0B press -> no eject (gate holds); panic /
numpad / Backspace unchanged.

Joe DiPrimaandClaude Fable 5 aa54655980 #118: the FLASHING eject invite fires -- generator OUT state + pilot keypad 
The last hop lands: a destroyed Generator now reaches its OUT display state
(stateAlarm 4 -- enum renamed from the placeholder "GeneratorRecovered";
[T3 inferred link, both endpoints byte-verified: the eject evaluator's
state==4 dead clause @0049fa1c and the authored alarm streams' conditions
4/5 -> gotoEngineering 0x80 + engEject 0x85]). Wired from the one crit
chokepoint (MechSubsystem::ForceCriticalFailure -> BTGeneratorMarkOut
bridge). Verified live: gen kill -> the quad-select columns FLASH
(RIO 0x37 fast-flash) -- the pod's guided "punch out now" trail.

Plus the authentic panel eject input: CONTROLS.MAP binds the desktop
NUMPAD to the pilot keypad (keypad pilot 0-9) -- while armed, any pilot-
keypad key fires the eject (the binary's only armed binding); un-armed
they feed program entry.

The full 1995 eject experience is now live: alarm -> flashing invite trail
-> lit Panic button -> press (Panic / numpad / Backspace) -> punch-out ->
death without honor -> respawn.

Joe DiPrimaandClaude Fable 5 417008a6d4 #118 faithful settlement: MFD soft keys NEVER eject -- panic/keypad only 
The streamed .CTL dump (BT_CTRLMAP_LOG, 109 records on the madcat) settles
the eject-input question from CONTENT: no 0x200000 record exists -- the MFD
soft keys carry their authored per-page routes unconditionally (elem 0xB on
a weapon eng page = msg 0xB EjectAmmo, the round eject), so they must never
route to pilot-eject. The invite-cell routing (b9430cc) hijacked exactly
that key -- the operator's "bottom left button self destructed" -- and is
REMOVED.

The faithful model, now fully grounded: the flashing engEject soft-key LAMP
is the INVITE indicator; the eject PRESS is the guarded PANIC key (no
button-space consumer in the image -> it reported through the pilot keypad
matrix; the 0x3D->keypad wire stays) or any pilot-keypad key while armed.

Verified: armed + soft-key 0x0B press -> NO punch-out (authored function
preserved); panic path unchanged.

Field-caught by the operator within minutes: the blanket MFD key-space
routing (0x00-0x2F) made the DISPLAY navigation key eject the mech
mid-page-switch while armed. Narrowed to exactly the guarded PANIC button
(0x3D) and the three eng-page EJECT INVITE cells (0x0B/0x23/0x03, the
addresses the engEject 0x85 alarm lamp flashes on). Navigation is safe
while armed; the flashing cell still punches out (re-verified through the
click seam: armed -> press 0x0B -> PUNCH-OUT).

Joe DiPrimaandClaude Fable 5 b9430cc5a7 #118: the MFD eject cell ejects -- all pilot-keypad-space keys route while armed 
The operator's pod flow ("the engineering panel's bottom-left button flashes
EJECT, you push it") is input #3 of 3. The eng-page eject cell resolves to
MFD side-column addresses 0x0B/0x23/0x03 (kBTEngBankTop - 4 per bank), and
the binary's ONLY armed eject binding is the KeyboardPilot group (0x200000
-> mech msg 0x19; exhaustive 0x200000 scan: no other consumer) -- so on the
pod those keys report through the pilot keypad matrix. Desktop mirror: MFD
key-space presses (0x00-0x2F) and Panic (0x3D) also land as pilot-keypad
keys. Outside panic mode the binding is mode-masked dead -- normal MFD
operation untouched; armed, the flashing cell (or any keypad key -- the pod
semantic) punches out.

Verified through the click seam: gens dead -> armed -> press 0x0B ->
PUNCH-OUT.

All three eject inputs now live: Panic button, Backspace/pad LeftThumb,
and the flashing MFD eject cell.

Joe DiPrimaandClaude Fable 5 0bd9bb6f51 #118: the FLASHING eject invite is authored -- engEject alarm items found 
BT_LAMP_LOG now dumps each gauge-alarm stream item as it reads
([galm-item] sub/cond/itemCond/lampCode). First dump against the shipped
content settles the operator's "shouldn't something flash?" question:

  GeneratorA itemCond=4 -> lampCode 0x85 (engEject) + 0x80 (gotoEngineering)
  GeneratorA itemCond=5 -> lampCode 0x85 + 0x80

The 1995 pod FLASHES "GOTO ENGINEERING" and the engineering page's EJECT
cell when a generator goes OUT (conditions 4/5) -- the authored eject
invite. The Panic button lamp itself is solid by authoring ([lamp] 0x3d <-
0x3c, no flash bits) -- both halves of the field observation are genuine.

Remaining: the BT_KILL_SUBSYS scalpel skips the authentic state-4
transition, so the flash did not fire in the bench; verify a genuinely
damaged/overheated generator reaches state 4/5 and lights the invite
(the #118 "Generator Out vs !=4 clause" tail).

Joe DiPrimaandClaude Fable 5 751b1159b5 #118: the eject slot graphic lands -- BitMapInverseWipeScalar reconstructed 
The operator's field report ("eject slot flashing but no graphic in it") was
the tracked-NULL bring-up stub in BallisticWeaponCluster. Reconstructed the
missing gauge class from the binary:

- BitMapInverseWipeScalar @004c61c8 (vtable 0x518a14; base @004c5e84,
  Execute @004c5fb8, BecameActive @004c5fa4): a bitmap COLUMN SWEEP whose
  level tracks a live Scalar -- two spans with INVERTED colour pairs,
  [0..level] fg colorA / bg colorB, remainder the inverse.
- Wired per the binary call site (part_014.c:2312): bteejtm.pcc at (0xF,0)
  on the weapon's eng port, colours 0/0xFF, watching the weapon's
  PercentOfEject (@0x3F8, the round-eject 0..1 progress) via a new
  complete-type bridge BTWeaponPercentOfEjectPtr (databinding rule).

At idle (level 0) the EJECT graphic now renders in the slot; during a
round-eject cycle it sweeps with the countdown. BTEEJTM.PCC ships in
content/GAUGE (the loose gauge bitmap set). Smoke-tested: constructs clean.

Joe DiPrimaandClaude Fable 5 611b1a8bbd #118: the PANIC BUTTON ejects -- keypad-bank routing + the 0x17/0x19 id bug 
Two finds close the press path the operator field-tested:

1. The pod's guarded PANIC key reports through the PILOT KEYPAD bank -- the
   binary's ONLY panic press binding is keyboardGroup[KeyboardPilot].Add(
   mode 0x200000, mech, 0x19) (FUN_004d266c); there is NO buttonGroup[0x3d]
   consumer (0x3d is the lamp address). The desktop Panic click now ALSO
   lands as a pilot-keypad key (PadRIO::EmitButton -> EmitKeypad), so the
   armed-mode binding fires; a healthy press stays a mode-masked no-op,
   exactly the pod behaviour.

2. KeypressMessageID resolved to 0x17 via enum-chain arithmetic; the binary
   passes LITERAL 0x19 (two mapper ids are unreconstructed). The armed
   keypad send arrived at the Mech as msg 0x17 -- no handler, silently
   swallowed. Pinned to 0x19 (Mech::EjectPilot's id on the OWNER receiver --
   the collision is the design).

Verified headless through the REAL click seam (BT_BTNTEST=61): generators
killed -> panic-arm ON -> screen-click Panic -> [lbe4key] unit 0 mode
0x650421 -> PUNCH-OUT. Also: IsDisabled eject refusals now log; [padkey]/
[lbe4key] seam tracing under BT_PAD_LOG.

Still open (cosmetic): the flashing eject slot on the engineering MFD shows
no graphic -- the streamed page element's pixmap is unreconstructed.

Joe DiPrimaandClaude Fable 5 0089b3284f Eject firsthand prep: G = coolant Flush binding + BT_FLUSH_HOLD scalpel 
The Flush ACTION existed in the input engine but no key was bound in the
shipped CONTROLS.MAP -- desktop players could never hold the flush. G (free)
now maps to it. BT_FLUSH_HOLD=<frames> extends the BT_FLUSH_TEST scalpel
past its 60-frame edge test for tank-dry benches.

Dry-run finding (fl.log): a full flush drains the tank to 0/14 in ~30 s,
but does NOT arm eject by itself -- InjectCoolant moves tank coolant INTO
the loops (the bank RISES), and idle heat draw is too slow to burn the
loops down to the 5% arm threshold in minutes. Firsthand arming needs
sustained fire after tank-dry (or coolant-loop leak damage / generator
loss). Matches the binary's intent: eject arms when LEAKED nearly dry.

Joe DiPrimaandClaude Fable 5 8165cee9da #118: the eject option comes alive -- per-frame arm chain closed (FUN_004a9b5c+0x10) 
The evaluator's "unexported caller" found by E8-scan: the Mech MASTER
PERFORMANCE (FUN_004a9b5c, in the 004a977x..004ab188 export hole) calls
EvaluateEjectPermission as its FIRST act every frame. Without that call the
port's ejectPermitted stayed at ctor-0 forever -- the panic-armed mode never
raised, so the PANIC lamp never lit and testers "never saw the option for
eject come alive". Restored at the top of Mech::PerformAndWatch (masters
only, like the binary).

Mislabel swept: mech+0x414 is ejectPermitted, NOT "missionReviewMode" -- the
mapper's @004d196c edge-watch arms PANIC mode 0x200000 from it (the real
review mode is the GLOBAL DAT_004fd550; btl4pb now reads that global, the
GetMissionReviewMode stub is retired, mapper member renamed
previousEjectPermitted).

Verified live: kill 4 generators -> "[eject] panic-arm mode ON" -> the
miniconsole Panic button lights dark->bright (pixel captures; the pad panel
shades it from the same PadRIO lamp state the pod's physical button uses) ->
BT_EJECT_AT press -> PUNCH-OUT -> respawn heals -> mode disarms -> healthy
presses REFUSED. BT_EJECT_LOG=1 logs the arm edges.

Note: no shipped gauge rides mode 0x200000 -- the 1995 eject indication is
the button lamp; the weapon-eng MFD "UNJAM/EJECT" is the ammo-jam indicator.

Re-read the material damage watcher RAW (@004573e4 ctor / @00457784
change-push): 16 floats snapshotted, damaged = pristine x 0.1 (literal at
the MakeMechRenderables call site, watching zone+0x158), linear lerp, 13
floats written back, then FUN_0048d4d4 -- which is "flush_material": a dpl
command-stream marshal (opcode 100) to the i860 division card. The
material->ramp->texel response curve was CARD firmware and is not in
BTL4OPT.EXE; logged as an open question (ask: firmware/DIV docs/period
screenshots).

Field reconciliation, measured live: one 25-pt hit (ERLG class) snaps a
77-pt arm 0 -> 0.3247 in a frame -- "a single missile leaves visible
armor damage" holds under the linear curve for heavy hits; 2-pt ERS creep
(the leg-audit weapon) is the invisible case.

Bench additions: BT_WALK_ZONES=<name-list> walker filter (concentrated
per-region audits, scratchpad/night10/legwalk.sh) + BindArmourDamage
ORPHAN inventory under BT_ARMOR_LOG (proved every drawn op is

Joe DiPrimaandClaude Fable 5 fe48accb6b #87 root cause: the level-crossing zone-record send was missing -- observers never saw damage 
The binary's effect watcher (FUN_0042aa2c) raises
ForceUpdate(DamageZoneUpdateModelFlag) when a zone's damageLevel CROSSES a
band-descriptor threshold (FUN_0042a5f4, master-gated on entity+0x28 & 0xc)
-- that send is how every other pod's replicant learns zone levels
mid-fight. The port's band hub kept only the graphic-state branch, so an
observer's copy sat at 0.0 until destruction: no enemy hull darkening, no
doll movement, ever (the night-10 "no armour discoloration" report).

Restored the level branch with the already-reconstructed DescriptorCrossed
(@0042a5f4) + the master gate on both branches (mesh swap still runs on
every instance). 2-node verified: A-side armour watcher pushed 114 level
changes; every replicant peak matched the master's finals to 4 decimals
(dtorso 0.9321 == 0.9321).

Render path cleared separately (gotcha #23 discharged): BT_ARMOR_FORCE 0/1
A/B captures prove the tint renders (hull -> charcoal at 1.0). Solo
perception is the authentic economy: 2-25 pt lasers vs 68-185 pt pools.

Bench: zonewalk.sh node A now carries BT_ARMOR_LOG + BT_SHOT_EVERY (the
standing zone-replication receipt) + digest_walk.py; armorpx.sh is the
force-pair pixel rig.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
 2026-08-03 11:32:26 -05:00
Joe DiPrimaandClaude Fable 5 00dfbf8f9f #124 RESOLVED against the authored skeleton: the pick's zone is the 
struck drawn segment's dzone, ALWAYS -- the cylinder embellishment removed

The open question ('what zone did 1995 designate for hull hits') was
already answered in the KB's #73 dig [T0+T1]: no software pick writer
exists -- the pod's pick was a dpl scene intersection, struck triangle
-> DCS segment -> its SKL-authored dzone; the cylinder lottery was only
ever the UNAIMED path (missiles/splash/rams). The live segpick dump
completes it with the authored data: the madcat's pickable skeleton is
18 segments -- hip, shoulders, guns, thighs, knees, ankles+toes, and
ONE hull piece (jointshakey -> dtorso). No ltorso/rtorso/utorso/rear/
door/searchlight segments exist. Aimed fire at any torso panel
authentically designates CENTER TORSO; the side/rear/upper panels strip
via the unaimed path.

Changes:
* the shared-carrier -> cylinder override (yesterday's embellishment)
  is REMOVED: triangle hit -> that segment's dzone, period;
* SegAimPoint: the walker's hull anchor moves from the joint ORIGIN
  (crotch gap -- rays sailed between the legs to the terrain sentinel)
  to the carrier segment's cull center (the chest);
* [picktri]/[pickwin] diagnostics grew tri/seg/zone fields -- three
  consecutive 'mystery' regressions in this stretch were the STALE-EXE
  trap (CWD-relative cmake --build from content/ resolved to a
  nonexistent dir and the old binary kept running) -- the harness doc's
  warning, hit again.

Final zone-walk matrix (spinning target, real MP, full cycles):
limbs 55/70 in-zone (legs/feet 6/6; arm strays = hull/occlusion);
hull-family aims -> dtorso 56/69; victim consumption matches. The
night-10 field table now reads as this model's fingerprint: 'only LCT
gets hits' from aimed energy IS the pod -- one hull piece, dtorso.
What was actually broken and is now fixed: the sphere mis-picks
(rgun-from-a-dtorso-aim class), the unaimed path's 180-degree frame,
and the vertical scatter.

Joe DiPrimaandClaude Fable 5 1a3c268278 #124: the aimed pick now intersects the DRAWN GEOMETRY -- sphere 
approximation retired; shared-hull hits route through the cylinder

The zone-walk matrix caught the pick red-handed: with the servo
verifiably holding the reticle on the dtorso segment, the per-segment
BOUNDING-SPHERE pick returned rgun/ruleg -- the gun pods and legs
thread the ray before the torso from most angles (its own comments
admitted a foot could be unhittable behind its own knee). The 1995
pick was a dpl scene intersection against the drawn geometry.

Restored that semantic:
* BTGetPickMesh caches each segment d3d_OBJECT's triangles CPU-side
  once (its own BGF VB/IB, managed-pool locks); MechSegmentPick now
  runs sphere PRE-FILTER -> Moller-Trumbore nearest-hit across the
  threaded segments' posed meshes; the old smallest-sphere selection
  survives only as the no-triangle fallback.
* Segments claimed as CARRIER by 2+ zones (the shared hull: madcat
  seg 4 carries dtorso+ltorso+rtorso+utorso+rears) cannot resolve one
  zone from geometry -- those hits return zone -1 WITH the accurate
  triangle point, and the victim's bit-verified (frame-fixed) cylinder
  assigns the panel by band/wedge. Unique carriers (legs, feet, arms,
  gun pods) keep the direct zone.
* ZoneAimPoint: the walker aims at a zone's VISUAL center (largest
  pick object's cull-center) instead of the segment origin -- joint
  origins made feet/lower legs strike the part above.
* Walker upgrades from live operation: 3-column truth (aim/pick/land),
  engage gate, damped servo with polarity watchdog, approach port.

Zone-walk verdict (full cycles, spinning target, real MP): limbs 5-6/6
direct in-zone; every hull panel routes CYL; the victim's landed zones
now include ltorso/rtorso/reardtorso/rearutorso/rearrtorso -- the
panels night-10 reported unhittable. Residuals tracked on #124:
rtorso/utorso aim-anchor placement, doors/searchlight small-zone
sample, twisted-torso twist-sign verify.

Joe DiPrimaandClaude Fable 5 16e75d6e1a #124 bench: the ZONE-WALK MATRIX -- systematic per-panel targeting, operator-watchable 
The precision rig the operator specified: two nodes, target visible,
every zone aimed at deliberately through the REAL reticle/pick path.

* BT_SPIN_SELF=<deg/s> (target node): rotates the node's own viewpoint
  mech in place (the BT_SPAWN_AT write pattern per frame) so every
  aspect passes the shooter's boresight; the operator watches this
  node's paper doll take the hits.
* BT_ZONE_WALK=<secs/zone> (shooter node): walks the target's damage
  zones in order, resolves each zone's carrier segment's live world
  position (BTResolveSegmentWorld + the new BTMechZoneSegAndName
  bridge), SERVOS the torso twist + aim elevation until the centered
  reticle ray (BTGetAimRay) points at the segment, fires 3 laser
  pulses, advances. [walk] ZONE/FIRE/HOLD on A pairs with [dmghit]
  zone/level lines on B.
* scratchpad/night10/zonewalk.sh: launch both + relay, map sed'd to
  grass/day, NO kill timer -- the session stays up for observation.

Hard-won servo constraints (documented in test-harness.md so they are
never relearned): the ENGAGE GATE (ray live + range<150 + bearing<1.1;
outside it RELAX the twist -- servoing at the twist limit while the
goto marches is a limit-clamp fight that visibly shakes the mech, and
a 0.55 gate deadlocks against the goto's ~0.55 resting bearing); YAW
POLARITY -1 (the twist cell's angular sense is opposite atan2(x,-z)
world yaw -- operator-observed live, the SECOND witness for the #124
SelectSlice twist-sign flip) with a divergence watchdog that
self-flips; damped correction (gain .40, cap .025/frame -- the aim ray
lags the twist write a frame); and a one-shot approach PORT to 100u
off the target instead of a cross-map march.

First live run: walker cycles zones, settles, fires; the target's
luleg climbed 0.458->0.523 under its own aimed pulses -- aimed shot,
correct panel, damage consumed.

Joe DiPrimaandClaude Fable 5 b0b7adc4ea #124 CORRECTION: the frame adapter is a Z-REFLECTION, not a pi rotation -- 
proven by the mech's own pods

The first fix (c5dfb00) negated x AND z. The operator challenged it:
'they couldn't hit rear panels AT ALL -- a 180 rotation couldn't explain
that' -- and a rotation would also have relocated rear damage, not
erased it, while the bench premise (the dummy faces its attacker) was
assumed, never measured.

The zero-premise probe (BT_ASPECT_TEST): four self-impacts at known
WORLD cardinals + one at each weapon's PHYSICAL MUZZLE position -- the
mech's own asymmetric geometry as the left/right anchor. Measured:

* WorldToLocal is a clean R(yaw), no hidden terms (yaws -30/150/40 deg
  all consistent);
* our frame: RIGHT = +X -- SAME as the 1995 ring (W0/W7 = Right*) --
  and FORWARD = -Z, flipped vs the ring's Front*-in-+Z-arc;
* under the pi rotation the pods CROSSED (left muzzle -> rtorso);
  under z-negation every anchor lands its own side.

So: negate local z only, and -- since a reflection reverses angular
direction -- the SelectSlice torso-twist term flips sign with it
(twist was 0 in all probes; twisted-torso verify tracked on #124).

Anchor acceptance (fresh exe, third yaw): LRM15_1 left pod -> ltorso,
LRM15_2 -> right wedges, left/right arm muzzles -> larm/rarm, nose ->
front cells, tail -> rear cells, flank cardinals -> rgun / left wedges.

The BT_ASPECT_TEST probe + BTWeaponMuzzleWorld bridge stay as bench
scalpels.

Joe DiPrimaandClaude Fable 5 c5dfb002f3 #124: hit-location ASPECT was rotated 180 degrees -- the resolver now speaks the 1995 frame 
Night-10's systematic targeting audit (rear panels unhittable from
direct fire, Owens left torso hitting the RIGHT weapon pod and vice
versa, missiles favoring the far side) measured down to one geometric
fact: the authored wedge ring puts the Front* cells in the +Z arc
(slice-name audit, bit-verified tables), i.e. the 1995 resolver frame
has mech-forward = +Z -- while OUR engine's entity frame carries
forward along -Z. Bench proof: a victim facing its attacker took
frontal beams at local z = -4..-10, theta ~270 deg, resolving the
REAR-named cells (zones 12/14/15) every time.

The two frames differ by a pi ROTATION about Y -- rotation, not
reflection, because the field flank observations CROSS (left->right)
rather than persist. ResolveHit now rotates the local impact into the
cylinder's frame (negate x and z; y untouched; handedness preserved so
the SelectSlice torso-twist add keeps its sign).

A/B (172 resolves, live missiles+beams on a facing victim): before
theta~4.7 -> rear zones only; after theta~1.42-1.59 -> utorso/dtorso/
ltorso/rtorso/arm -- the front-authored cells, with the per-burst
re-roll scatter intact.

NOT this bug: the "one band LOW" Y-axis half of the night-10 table --
that is #16 (pick-ray boresight parallax, code-confirmed, still open).

Joe DiPrimaandClaude Fable 5 1df2c571ee #119: heatLoad filter restored to the POD's 28 Hz sample cadence 
The clipping coolant-leak voice ("warning... war... warning coo...")
measured to a ReportLeak relaxation oscillation at a drained tank:
draw = zoneDamage x heatLoad hunts across the authored 0.0025/0.003
hysteresis band (constants byte-verified) as the dry sink's conduction
collapses and the tank trickle refills it. State machine, constants,
refill dynamics and the sequencer's chase-and-cut stop (T0 AUDSEQ.cpp)
are all the binary's own -- the ONE divergence was the 15-sample
heatLoad filter: per-Perform in the binary = a 0.536 s window at the
pod's 28 Hz, but only 0.25 s at the port's ~59 fps -- heatLoad twice as
twitchy, the flap at double the pod cadence (the myomer-kinetic dt-less
class, third instance).

UpdateHeatLoad now accrues real time and samples at 28 Hz on any
machine (catch-up capped at the 15-sample window). Per-instance clock
in a static map -- the heat-family layouts are factory-size-locked
(sizeof(Myomers) == 0x358 exact), no new members. Ctor/reset prime
calls sample unconditionally.

A/B (260 s leak-to-empty bench): trigger fires 12 -> 8, transitions
11 -> 7. The residual slow restart at a bone-dry tank is authentic 1995
behavior (same engine sequencer chase-cut); a minimum-retrigger
interval would be an opt-in deviation for the operator to decide.

Joe DiPrimaandClaude Fable 5 1efe8efc68 #118 tails: death score cost + the DeathWithoutHonor console notice 
* SpecialCaseDeathPenalty restored to the engine ScenarioRole (SCNROLE.h/
  .cpp) -- the 4.10-only role field the 2007 WinTesla source dropped
  (record slot [1] after KillBonus, fail-hard read; role+0x20; the
  DefaultRendererRate pattern). Its consumer decoded from the @004c05c4
  export gap (@004c07cd, missing from the #52 reconstruction): every
  death with advancedDamageOn hands the ENGINE base ScoreMessageHandler
  (@0042da20 == PLAYER.cpp:138, a DIRECT call bypassing the BT type
  Verifies) a type-1 award of -penalty. Wired verbatim. Shipped content
  authors the key nowhere -> cost 0 in the field. NUANCE [T4]: the 1995
  engine adds at Player+0x1c8, which no BT scoreboard reads (+0x278) --
  the pod's cost may never have displayed; our single-cell port shows it.

* The eject console notice: FUN_004c198c IS the
  ConsolePlayerMechDeathWithoutHonorMessage ctor (T0 BTCNSL.CPP survives
  and is compiled) -- "death without honor" is the punch-out record.
  BTPlayerEjectBookkeeping now sends it to the console host through the
  same ConsoleClientID path as the VTVDamaged notify, then latches
  suppressConsole: the eject notice REPLACES the death notify. Verified
  two-node: "notice -> console host 1" fires on the ejecting node; the
  relay-side delivery of client-5 traffic is a pre-existing question
  shared with the never-observed VTVDamaged sibling (operator-console
  workstream).

* Eject alarm-10 audio: resolved NEGATIVE -- the five Eject*.wav ship in
  AUDIO/ but BTL4.RES references them nowhere (orphaned like the SQUAT
  clips); wiring them would be a stand-in. Operator-optional deviation.

* RIO 0x38 panic control: deferred with the plumbing documented (the
  glass Flight-Controls window already renders the 0x38 bank; consumer =
  read buttonGroup[ButtonPanic] alongside the binding-engine edge) --
  pod-hardware-only, untestable on this bench.

Two-node verify (fresh-exe rerun after a stale-exe trap): REFUSED
healthy, PUNCH-OUT after generator kill, death + wreck swap + smoke +
un-wreck warp all replicated on the observer, respawned mech refuses
again, console notice fired.

Joe DiPrimaandClaude Fable 5 e996be249d EJECT/PANIC wired: Mech::EjectPilot (id 0x19 @0049f854) + the crippled-mech gate 
The button died twice before reaching game logic: no handler (0x19 was
unregistered) and no sender (the pod's panic was a control bit, not a
mappable). Both halves reconstructed from raw disasm -- the handler AND
its permission evaluator sat in export gaps.

@0049f854 EjectPilot: press-only; gated on ejectPermitted (@0x414) and
!IsDisabled; console eject notice (relay wire = tracked tail; the
suppressConsole@0x258 latch that prevents the death double-notify IS
wired); graphicAlarm -> 10, which kills via the >=9 predicate; then a
self TakeDamage {inflicting=SELF, zone -1, Explosive, amount =
ScenarioRole::killBonus}. Role layout byte-settled via the role reader
@00429bec dest offsets + the ctor record copy: +0x1c IS killBonus, +0x20
is the 4.10-only SpecialCaseDeathPenalty, +0x28 returnFromDeath (all
prior citations reconciled). KillBonus authors NOWHERE in shipped
content -> the charge is 0 and the ALARM does the killing: our bench
outcome is the pod outcome.

@0049fa1c EvaluateEjectPermission: eject only from a CRIPPLED mech --
bank coolant fraction < 0.05 | zero live generators | live weapons
below mech+0x448 (no exported writer: zero, clause inert) | leg-gimped
novice. A healthy mech REFUSES the button; no free resets.

Input: binding-engine "Eject" action -- Backspace / pad LeftThumb
(default profile + shipped CONTROLS.MAP). Bridges per the databinding
rule: weapon/generator/bank/player reads land in their complete TUs;
MechSubsystem gains the both-cells destroyed accessors (gotcha #22).
Bench scalpels: BT_EJECT_AT=<frame> (path-identical synthetic press),
BT_KILL_SUBSYS now takes a comma list.

Verified single-node: healthy press REFUSED (x2), four generators
killed, next press PUNCH-OUT -> death, wreck smoke, respawn; the
respawned mech refuses again (permission re-evaluates after Reset).
Death rides the normal damage/death chain, so MP replication is the
proven path. Tails tracked: console relay notice, RIO 0x38 panic
control, alarm-10 eject audio/canopy, SpecialCaseDeathPenalty consumer.

Joe DiPrimaandClaude Fable 5 e1ae92264a #96: the sim TIME MODEL closed from bytes -- myomer kinetic term restored to the faithful 28 Hz 
The open question under every heat bracket was what the 1995 sim does with
time. Answered at the byte level:

* FUN_0041c018 IS the arcade Simulation::PerformAndWatch: slice =
  (till.ticks - last.ticks) / DAT_0052140c, stored, Perform(slice) --
  VARIABLE-STEP in real SECONDS, line-for-line the WinTesla SIMULATE.cpp
  body. Every dt-carrying reconstruction is unit-faithful; no tick/second
  gap exists anywhere.
* The myomer heat term's ONE caller is the unexported MyomersSimulation
  body @0x4b8b9a (E8-scan + raw disasm; export gap): once per Perform, raw
  slice, gated measuredVoltage>0 only. The dt-less kinetic pulse therefore
  fires at the FRAME cadence -- 28 Hz nominal, sagging under load
  (emergent hardware, not a code constant).
* Mover velocity is u/s (dead-reckoner @0x421f7c: pos += vel x ticksD/28),
  so the v operand is unit-faithful too.

The 0.5 "loaded-rate" witness bracket is RETIRED -- it modeled the sag as
a constant, wrong in exactly the reported scenario (open-field cruising is
a light scene; the pod held ~28 there). kSeekHeatCalib = 1.0.

Measured at the faithful rate (madcat cruise benches): recommended gear
equilibrates ~1450 -- inside the authored degradation band as a SOFT 20%
output governor (heatFactor = 1 - d^2/range^2), weapons untouched at
~110-150, ZERO jams, zero bay fires from movement alone; supercharge
~1770 (deep governor -- the manual's own expert-mode warning). That is
the authored system: degradeT=1000 is governor onset, failT=2000 the
cliff, and the coolant-loop controls are the player's lever.

New leads filed in open-questions: the climb term's gravity operand
samples 0 (bridge points at a dead cell); the engine Mover's own gravity
subtraction is per-frame dt-less (port impact unread); gait-noise phantom
acceleration feeds the accel term.

Joe DiPrimaandClaude Fable 5 d3de5f94ee #87/#96: 'mechs die with lightly damaged armor' AUDITED -- no port bug; it's ammo cook-off 
Byte-level audit of the entire damage chain vs the binary, all links exact:
zone stream reads (@0041df5c == engine DAMAGE.cpp), ctor normalization
(@0049ce50; constants 1.0/1e-4/0.5; shipped cells uniform 1/armorPts),
TakeDamage @0041e4e0, the BT override @0049c690 (vital/leg 1.0/0.5/0.0),
CriticalHit @0049ccc4 (0.5 fraction, 1.0 cap, authored-percentage cap),
cook-off chain (@004bc3fc per-salvo stamp / @004bd300 rounds x amount /
@004ac274 divide across the bin's plugged zones).

Measured kill route: 6 of 7 bench deaths were bay-fire detonations --
LRM15 bin 10 rounds x 50 = 500 into its ONE authored carrier zone
(content: madcat bins single-zone; 15 of 22 zones vital) -> one
application 0->1.0 -> instant death, armor bright everywhere else.
Field logs confirm dominance (Rajel 12 bay-fire events, ConnMan 10).
The mech that died conventionally ended 0.97/0.93/0.92/0.85 charred --
darkening accumulates fine when mechs live long enough.

Levers: the #96 heat economy (arms the bay fires) and purge training
(EJECT hold extinguishes -- wired, logged, manual-trained in the pod).

Also corrected a wrong KB address: FUN_0041e4e0 was labeled '.DZM res
compiler' in decomp-reference.md/rendering.md -- it is DamageZone::
TakeDamage (byte-matches DAMAGE.cpp:379); swept both files.

Joe DiPrimaandClaude Fable 5 152249cb76 #95: the SCOREBOARD banked one missile per salvo -- credit the DELIVERED amount 
Two consumers of one impact, only one was ever verified: the victim gets
TakeDamage{amount=per-missile, burstCount=cluster roll} and applies it
burstCount times (armor was always right); the score post on the next line
sent the bare per-missile amount. An LRM10 salvo dealing 7-35 armor banked
3.5 points -- Rajel's "~3 points to score", to the digit.

Ground truth: the binary's score is the victim handler's tally (amount once
per applied burst @0x4a04da + crit bonuses) reported to the INFLICTING
player (the id-0x16 tail, deferred #45). The shooter-side stand-in now
posts amount x burstCount -- the identical figure handed to the victim, at
the identical one-post-per-TakeDamage granularity. Same pass:

* splash never credited score at all -- the binary tallies every
  TakeDamage; now posted per splash victim (amount x falloff bursts);
* the bridge credited the LOCAL player for ANY registered hit -- AI-master
  fire on the player, a dying mech's death-blast splash; now refused
  unless the shooter IS the local vehicle (MP unaffected: only local fire
  carries live damage on a node);
* direct-fire unchanged -- beams author burstCount=1 (emitter.cpp:355).

Verified per the harness doctrine: single-node field composition (madcat,
real fire, real enemy) 22/22 impact credits paired at damage x burst, zero
bare 3.33 posts; two-node replicant-victim run BOTH directions 31/31
paired across three missile authorings (3.33/2.0/5.0 per-missile) + 25-pt
ballistics, leftovers all burst-1 beam amounts. test-harness.md gains the
map=grass note (MP.EGG authors cavern/night; GOTO mechs shoot rock).

Joe DiPrimaandClaude Opus 5 08ca66e5b5 weapon SPEC AUDIT: the fleet's authored numbers in one pass -- missile delivery fully reconciled 
"do we need to audit every possible weapon independently?" -- one dump answers
all of them.  [wspec]/[wspec-msl] (BT_SPEC_LOG) print every weapon's AUTHORED
damage/recycle/range/heat + missile count and post-divide per-missile at build.

THE KEY DISCOVERY: the catalog's FULL-NAME loadouts (madcat, thor, avatar,
sunder, vulture, loki, blkhawk, owens) author DIFFERENT weapons than the
4-char variants (mad1, thr1, ...) -- and the named ones are what players fly.
Every night-9 field number reconciles exactly:
    madcat/thor LRM15 = 50 total -> 3.33/missile (field: 3.33, bursts 3..15)
    avatar/sunder LRM10 = 35     -> 3.50          (field: 3.50, bursts 2..10)
    vulture LRM20 = 65           -> 3.25          (field: 3.25, bursts 5..20)
    loki SRM4 = 35               -> 8.75          (field: 8.75, bursts 1..4)
Missile delivery is FAITHFUL across the real fleet: per-missile = authored /
count (divide confirmed live post-ctor), delivered total = per-missile x the
binary's Random(n)+n/4 roll = 25..100% of listed, zone-scattered.

The "80+ point hits" recollection fits the data as an ALPHA: madcat full alpha
= 50 + 25 (AFC100) + 6 + 2 = 83.  A single 4.10 salvo cannot exceed 65
(vulture LRM20).  The "3-5 points" reports read our [projectile] IMPACT
per-missile diagnostic as a total.

Also: bac1 is not a valid vehicle (unhandled AV at btl4+0xac4cd on spawn --
noted for a guard someday); wspec-msl now prints AFTER the ctor divide.

Joe DiPrimaandClaude Opus 5 9b1353bfbf ONE Explosion per salvo -- the port detonated every visual round, amplifying explosion sound + smoke + audio demand by the missile count 
The user challenged the 7% clock story ("i think its not just a 7% discrepancy.
did you base your analysis in the decomp") -- correctly.  The stop-path trace
it forced found the real amplifier, and it is byte-grounded:

THE ARCADE (byte-verified in the #95 work): FireWeapon @004bcc60 spawns ONE
Missile entity per trigger -- no loop, missileCount never read at fire.  One
Missile -> one detonation (@004be078) -> ONE Explosion entity: one 4-voice
sound + one authored smoke package per salvo.  The cluster's N-fold nature is
delivered as DAMAGE (burstCount), not as N explosions.

THE PORT: the N-round visual ripple (a deliberate [T3] port visual; its rounds
are damage-0 tracers) called BTSpawnRoundDetonation at EVERY round's contact --
N full Explosion entities per salvo, N x BigExpInt x 4 voices, N x the
explosion PFX, N=2..20.  Measured in a 100s solo missile bench: 559 explosion
sound setups; BigExpInt 208.  On observer nodes the stale-point mirror bug
(fixed in da70bd5) DOUBLED the train again.

One infidelity, three field symptoms:
  * Oracle: "prolonged smoke and explosion including sound" -- a staggered
    train of 6-20 overlapping BigExpInt instances per salvo reads as one long
    explosion+roar (Rajel correctly tied it to #84)
  * Ronin: missile-impact smoke "so much it functioned as a smoke screen"
  * #32: the saturating audio class was 1005 Static3DPatchSource requested=4
    -- each surplus detonation reserved 4 more voices

FIX: BTProjectile carries salvoLead; both detonation sites (target contact +
world/terrain burst) gate on it.  Master salvo: lead = round 0 (the damage
carrier).  Mirror salvo: round 0, so observers see exactly one explosion per
salvo at the live target.  AC/laser single rounds default lead=1 (one round =
one explosion, authentic).  Non-lead rounds keep their small tracer end-puffs.

MEASURED A/B (same bench): 80 of 96 contacting rounds no longer spawn the
package; 16 leads ~= the salvo count.  BigExpInt setups 208 -> 72 (~18
packages for ~16 salvos + deaths = one per salvo).  LaserExplosion unchanged
in kind.  Splash was already lead-only (splashBurst) -- damage totals move
NOWHERE in this change.

Also corrected the rack-tube comment that claimed "the binary's Missile
entities each launch from their own rack tube... their 12 detonations" -- there
are no 12 binary missiles; the ripple is ours.

The 28Hz audio-clock calibration from the previous commit stands, but is
demoted to what it is: a small systemic correction, not the explanation for
the field reports.

Joe DiPrimaandClaude Opus 5 6dbeb3d266 wreck smoke dies WITH the wreck; the audio/effect clock is calibrated to the byte-proven 28 
USER REPORT: "when you destroy a mech, it continues to smoke for a very long
time after the mech disappears... up to 30secs to a minute."

MEASURED (new [pfx] timed census with per-def particle attribution): the
death plume (psfx 1 DDTHSMK) was re-armed on a 10s cadence as a WORLD effect
(ownerTag=0) -- so neither the burial transition nor the respawn cleanup
(StopAllEntityEffects) could touch it.  The last-armed window kept emitting
over the empty spot for up to 10s after the hulk vanished, plus 6+-2s authored
particle lives, and back-to-back windows stretched the visible tail to the
reported range.  The re-arm itself is a marked PORT ADDITION [T3]; the binary
fired DDTHSMK once -- its 10s window + particle lives ended right around the
~17s hulk sink.  The authored design: the smoke dies WITH the burial.

FIX: the plume is spawned ATTACHED (BTStartPfxAttached, tagged to the dying
entity -- it also rides the sinking hulk now), and the burial transition calls
BTStopEntityPfx alongside the respawn cleanup that already did.  Verified over
a 175s run containing FOUR wreck events (the enemy kill + three player bay-
fire deaths): every plume's emission ends at its wreck's burial or respawn,
particles fade within ~8-11s, no orphan emitters remain.

THE COUPLING (user relay of Oracle: "prolonged smoke and explosion INCLUDING
SOUND... same lever?") -- CONFIRMED as a family: the binary's audio layer
times in FRAME COUNTS converted by the engine frame-rate global:
    AudioTime::Seconds_To_Frames == fmul [0x52140c]=28.0; fadd 0.5; round
    (@0x42c611, @0x42dd86 -- the 0x42xxxx cluster of the ~90 global consumers)
Our engine's DefaultRendererRate said 30: every audio duration, sequence
delay and compression window ran ~7% fast.  Calibrated to 28 [T1].  NOT yet
explained by this: a truly SUSTAINED/looping explosion sound (7% is not
"prolonged") -- the effect stop-path trace stays open on #114/#51.

Tooling: BTPfxParticle carries defIndex; [pfx] census (BT_PFX_LOG, 2s) prints
emitters + particles PER EFFECT SLOT with a timestamp; wrecksmoke.sh.

Joe DiPrimaandClaude Opus 5 2df1369168 #116 THE REAL STEAM CAUSE: experience never rode the lobby -- joiners' pages were authored by the HOST as the "veteran" fallback 
The user's question broke my first story: "did lynx host tho?"  He did (Oracle
joined LYNX's lobby that night) -- but more importantly the affected players'
logs read mode=steam, which gets the FULL menu, so the FeJoinOnly fix in
3109cfc patched a real gap (mode=join) that is NOT the path the affected trio
ran.  Oracle COULD see and cycle the selector; it still didn't matter.  Traced:

  * The steam lobby serialized exactly three member fields: nm / vh / cl.
    Experience never travelled.
  * The steam HOST rebuilds mission.pilots[] from the lobby roster
    (name/vehicle/color only), so every non-self page has EMPTY experience --
    and BTFeMission_WriteEgg stamps the "veteran" fallback on empty.
  * The steam JOINER writes NO egg at all (spec->eggPath[0]=0); his mission
    arrives from the HOST's console feed -- i.e. the host's egg, where HIS
    page says veteran no matter what his own console shows.
  * The host's own page keeps his menu choice only as slot-0 residue of the
    pre-roster self fill -- why BOTH hosts (Sauron AND Lynx) were clean while
    all three joiners heated in "standard".

FIX: experience is now published as lobby member data ("xp") beside nm/vh/cl,
unpacked into BTLobbyMember, and stamped onto each member's egg page in the
host's roster loop.  Both exported lobby entry points + PublishSelf gain the
parameter; the fe passes the local menu selection.  An older client in the
lobby simply has no "xp" -- the veteran fallback applies to THAT member only,
exactly the pre-fix behavior, so mixed-build lobbies do not break.

Per-player mixing (the original design, per the user: the sysop set each
user's tier; mixed matches were legal) now works over steam end to end: each
member's OWN choice -> lobby -> the host-authored egg page -> the console feed
-> that node's master player.

VERIFICATION BOUNDARY: builds both configs; the chain is code-traced; the
lobby legs need a real Steam session -- field re-test is a JOINER selecting
Standard and logging [exp] experience=1 heatModelOn=0 (plus the [fe] line on
both sides).  The 3109cfc join-trim selector stays: correct for mode=join.

Joe DiPrimaandClaude Opus 5 3109cfc49a #116: steam JOINERS were silently locked to VETERAN -- restore their experience selector 
Oracle isolated it: "standard mode still having heat and leaks only occurred in
steam not in solo.  Sauron and Lynx did not have the issue but Conn Man, Rajel
and myself did."  The night-9 logs close the case:

    affected  (Oracle/ConnMan/Rajel):  [exp] experience=2 heatModelOn=1
    clean     (Sauron's std sessions): [exp] experience=1 heatModelOn=0

CAUSE: the glass front end's JOIN layout trimmed the menu to "the mech list +
the JOIN button; everything else is the operator's call" -- and the experience
selector's hidden default is 2 (veteran).  So HOSTS got whatever they picked
(Sauron hosted the lobbies all night -> his standard landed), while every
JOINER launched as veteran regardless of anything they did -- which is why
Oracle's cycling-the-settings experiment changed nothing, and why solo (full
menu) never showed the problem.  heat >= veteran, hence "standard but heating".

DESIGN CONFIRMED BY THE USER before fixing: experience is PER-PLAYER by the
original design -- the sysop set each user's tier and mixed-experience matches
were legal.  Architecture already supports it end to end: each node's master
player reads its OWN egg's experience (btMission+0xE4 -> BTPlayer @004c0bc8),
so per-node choice IS per-player choice.

FIX: the join layout gains the GroupExperience selector (the selection->egg
write path is the pre-existing host path, field-proven).  Also: the front end
now prints "[fe] pilot experience=<x> (join|host/solo)" at launch, so every
future field log answers this class of report without asking anyone.

VERIFICATION BOUNDARY, stated plainly: builds both configs; the write path is
shared with the host flow which the field already exercises; the visible
selector + the [fe] line need one join-mode launch to eyeball, and the field
re-test is Oracle running a standard steam match as a JOINER and seeing no
heat.

Tooling note recorded in test-harness.md: bash-heredoc python collapses one
backslash level even single-quoted -- a "\n" arrives as a real newline and
replaces silently no-op.  Build backslashes from bytes([92]); verify replaces
by length delta, not by the script saying "fixed".  (This burned four edit
rounds tonight and several earlier C2001 hunts.)

Joe DiPrimaandClaude Opus 5 1bcee1f9eb #96: the effective-rate theory is corroborated -- upgrade the calibration provenance T3 -> T2 
Frame-rate testimony from the morning follow-up, now on record beside the bytes:
  * Oracle, asked if the pod frame rate was rock solid: "I think I could do as
    well with a flipbook"; heavy fights "would turn to a slide show".
  * Lynx (original era): "RP had a target frame rate of 30FPS.  It wasn't hard
    coded or locked.  BT never had a locked frame rate in 1st release
    testing... coming from 3.0, where 20FPS was a miracle."
  * The engine pacer's own design agrees: fixed budget + background fill + NO
    overrun catch-up (APPMGR.cpp, T0) = "target 28 but allowed to slip", with
    the 18.2065 BIOS fallback anticipating degraded timing.

Also settles epilectrik's open confirmation ("frame rate is advancing at least
some of the subsystems -- i have to fully confirm that"): ALL of them --
UpdateManager::Execute runs every interesting master every frame,
Entity::PerformAndWatch runs every executable subsystem per entity tick, no
throttle at any layer.  The crisp rule: CADENCE is frame-linked for
everything; only terms missing a dt multiply are rate-SENSITIVE.

Corollary worth keeping: a choking 486 generated LESS heat/s exactly during
the biggest fights -- the slideshow was mercy.  Veteran memory of seek-4
endurance encodes the LOADED rate, which is why bracketing by their consensus
is the correct instrument rather than a concession.

Follow-up filed in the KB: sweep the reconstruction for OTHER dt-less per-tick
accumulators (known: particle trail density, rendering.md; the 15-sample
heatFilter window is rate-dependent smoothing, benign).  Each found one should
normalize against the same 28-nominal/bracketed-effective pair.

Joe DiPrimaandClaude Opus 5 ac94ce6a31 #96: DISSIPATION AUDIT -- byte-faithful end to end; the cooling-too-weak hypothesis is DEAD 
"no guesses. we want to decompile and find the right answer" -- done.  Every
function in the heat-removal chain read from the decomp and diffed against our
reconstruction:

  HeatSinkSimulation @004ad924   E += pending; T = E/mass; alarms       EXACT
  UpdateHeatLoad     @004ad7f0   radiated = T x coolant; clamp(0.002x)  EXACT
  ConductHeat        @004ad8ac   exchange into linked + rebalance       EXACT
  ComputeHeatFlow    @004ad9ec   (T1*mScale - (E1+E2+pend2)/den) * tau
                                 * (1 - e^(-dt*k*(cool/cap)*flow/den))  EXACT
  BalanceCoolant     @004ada94   radiated-equalising move, 3 clamps     EXACT
  Condenser sim      @004ae4d8   mScale = clamp>=1((1-zoneDmg)*refrig)  EXACT
  Reservoir sim      @004aef78   inject-only; thermally passive         EXACT

Every term is properly dt-scaled -- the dissipation side is rate-INDEPENDENT.
The only rate-dependent energy term in the whole thermal system remains the
myomer kinetic generation, i.e. the calibration knob is pointed at the right
factor and nothing on the cooling side can absorb the blame.

LIVE chain verification (new [heatflow] census, incl. a RADIATOR tag on the
bank's own Performance, which the base-sim census could not see):
  Myomers 490 -> Condenser5 420 -> bank 337 -> ambient (relaxing onto the
  300K setpoint).  The exit exists, runs, and holds the bank just above 300.

AND ONE REAL FINDING -- my night-8 "no per-chassis cooling variation" claim was
WRONG, and Oracle's stated mechanism is vindicated to the digit:
  bank k = 0.1 x HeatSinkCount x 231000:   Owens count=5  -> k=115,500
                                           Thor  count=13 -> k=300,300
The Thor sheds 2.6x the Owens' heat through the mech's ONLY ambient exit --
"a thor could run seek 4 for extended periods because of the number of
heatsinks" is exactly the authored model.  My hsparm chassis comparison had
printed RESOURCE constants BEFORE the ctor's count scaling; the dump now
carries a warning to stop the next person misreading it the same way.
(The KB was never wrong -- open-questions.md:593 documented the radiator
scaling when task #9 landed it.  The wrong claim lived in my #96 comment.)

Joe DiPrimaandClaude Opus 5 c28555bdc9 #96: TRACE THE CLOCK ORIGIN -- the pod ran at 28 fps (byte-proven); myomer heat re-bracketed to 14 Hz effective 
epilectrik: "the issue seems to be related to a tick rate that advances the
heat accumulation... i need to trace out what the clock origin was."  Traced.

THE CLOCK ORIGIN [T1]: the DOS binary keeps its engine frame rate in the
global DAT_0052140c, set once at startup:
    0x401ace:  mov [0x52140c], 0x41E00000   = 28.0f     (nominal)
    0x401ada:  mov [0x52140c], 0x4191A6E0   = 18.2065f  (BIOS-tick fallback)
The DOS main pushes it straight into the ApplicationManager ctor (0x401189:
push [0x52140c]), and ~90 sites across the image fmul/fdiv by it -- it is THE
per-frame<->per-second conversion scalar of the whole 1995 engine.  The engine
executes every interesting master every frame and every executable subsystem
every entity tick (UPDATE.cpp / ENTITY.cpp, T0 -- no throttle at any layer),
so subsystem Performance cadence == this rate: the pod's myomer tick was
NOMINALLY 28 Hz.  My previous 30 Hz reference (the i860 BOARD frame) was
wrong by 7%, not the 2x the veterans hear.

THE RESIDUAL IS EFFECTIVE RATE, NOT NOMINAL: Oracle, on the halved build,
still asks "If you could please halve the myomer heat rate again.  We will
bracket to something reasonable."  A 486 host missing beats halves the real
Performance cadence without changing any constant -- and the 18.2 fallback
existing at all says slow paths were expected.  Statics cannot settle the
in-pod effective rate, so his bracket is the right instrument:

    effective default = 28 [T1 nominal] x 0.5 [T3 testimony calib] = 14 Hz
    BT_MYO_HZ=<hz> still overrides absolutely for bracketing
    the resolved rate now logs under BT_MYO_LOG, tier tags inline

Measured (Owens, seek 4, flat out): peak T 1007 -> ~640, degradation never
reached -- the halving Oracle requested, delivered as one auditable knob
instead of a silent constant edit.

KB: decomp-reference.md gains the DAT_0052140c section (~90 consumer sites --
whenever the decomp shows an unexplained mul/div by _DAT_0052140c it is
per-second<->per-frame at 28); btl4main.cpp's "30 = pod authentic" pacer note
corrected (30 kept deliberately for display smoothness, the divergence now
documented).  Candidate follow-up recorded: the frame-rate-dependent particle
trail density (rendering.md) should normalize against the same 28, which may
bear on Ronin's smoke-density report (#114).

Joe DiPrimaandClaude Opus 5 c791fae0f8 KB: new topic test-harness.md -- the bench machinery + the verification doctrine 
User mandate (2026-08-02): "do tests like this from now on" -- after the #110
grind bench, where the field composition (peer fire destroying an arm over the
wire) replaced the constructed proxy that had let #86 be called fixed while
players kept hitting it.

The topic carries two halves on purpose:

DOCTRINE -- what counts as VERIFIED:
  1. reproduce the REPORTED scenario, not a convenient adjacent one
  2. scalpel hooks (BT_SELF_DAMAGE_ZONE / BT_KILL_SUBSYS / BT_FORCE_*) locate
     defects; they support a "fixed" claim only with proven path-identity to
     the field composition -- and the field composition still gets run
  3. MP symptom -> two-node proof (master-side correctness says nothing about
     what a peer sees)
  4. visual symptom -> pixel proof (gotcha 23)
  5. coverage claims need the axis enumerated and measured (all gates, all
     chassis), because per-chassis behaviour lives in authored data
  6. an unexplained extra effect in a passing run means the run has not passed

MACHINERY -- the bench_common.sh contract (summarized, file = source of truth),
single-node and two-node skeletons (relay, ports, affinity, fire cadence,
GOTO_STOP standoff), process hygiene (stale-node taskkill first, never
double-background, teardown kill order, stale-exe tells), and log-reading rules
(capped diagnostics are not evidence of absence; alarm lines are not trends;
name the actor at every refusal; field logs have no gates set -- spawn-time
summaries ungated, per-frame traces gated).

section, reconstruction-method Key Relationships.  checkctx CLEAN.

Joe DiPrimaandClaude Opus 5 5d6ded73f0 #110: cross-pod verified BOTH ways -- the cascade replicates, and peer fire alone drives it 
Two two-node benches close the last stated gap ("no two-node run has watched a
peer's view of an arm death"), the second at the user's insistence on the REAL
field composition after the first used the self-damage scalpel:

1. mp_armchain.sh (scalpel): B self-destroys dz_rarm mid-fight.  A's screen
   receives the whole cascade -- [zone-repl] dz_rarm lvl 0->1 AND the cascaded
   dz_rgun lvl 0->1 -- plus the respawn reset coming back clean (1->0).  B's
   post-cascade AFC pushes turned out to be the RESPAWN RE-ARM, correct
   behavior, not a gate failure.  (Also confirmed: the self-damage harness
   dispatches a real Entity::TakeDamageMessage -- the identical path a peer's
   round takes, so the scalpel and the field share every line from the handler
   down.)

2. mp_armgrind.sh (the field composition): stand-off at 180, NO self-damage
   anywhere, A grinding B with real cross-pod fire for six minutes.  On B:
     * 25 incremental arm-zone hits from A's weapons via the cylinder tables
       (dz_rgun reached 1.0 from pure accumulation -- 15 cascades on rehits)
     * dz_rarm finished by B's OWN AFC bay cooking off (AmmoBinAFC100 BAY FIRE
       350, half into dz_rarm) -- itself lit by A's fire crits: peer-originated
       end to end
     * [cascade] zone 9 -> AFC100 + AmmoBinAFC100 + Condenser6 force-failed,
       fire gate refusals logged
   On A: [zone-repl] dz_rarm 0->1 and dz_rgun 0->1 -- the shooter SEES the arm
   and pod die.  B symmetrically received A's torso deaths.

Also: DamageZone::ReadUpdateRecord gets a change-only [zone-repl] diagnostic
(BT_MP_LOG) -- the probe that made the peer side measurable; mp_armgrind.sh
opens with the stale-node taskkill the other benches already had (a leftover
node from an aborted launch joined a later lobby as a third instance).

Joe DiPrimaandClaude Opus 5 614849b4a6 #110 coverage: all 8 chassis + all 3 weapon-class gates verified through ZONE death 
Answering "are you 100% positive this works for every weapon type" -- it was
not a yes when asked, and the gaps were closed with measurement rather than
assurance:

1. AUTHORED DATA, all eight chassis (zonesweep.sh; the [zone-armor] dump now
   carries the zone NAME):  every arm zone AND every missile-rack zone on every
   chassis authors descend=1 (ava/bhk/lok/mad/own/snd/thr/vul); every gun/rack
   zone lists 1-4 critical subsystems; doors are inert (0/0/0); bhk uniquely
   adds destroySibs=1 on its arm chain.  No chassis is missing the cascade
   authoring.

2. WEAPON-CLASS GATES, end to end through a ZONE death (not direct weapon
   destruction, which was #86's verification gap):
     ballistic  AFC100  (projweap gate1)  -- dz_rarm,    ava1   [prior commit]
     energy     PPC     (emitter gate)    -- dz_larm,    ava1   [prior commit]
     missile    NRK5_2  (projweap gate1)  -- dz_rmissle, own1   [this pass]
        [cascade] zone 12 -> NRK5_2 + AmmoBinNRK5_2 force-failed
        [ammo] NRK5_2 -> NoAmmo (gate1): destroyed=1
   All three fire-gate code paths are now exercised by the cascade.

3. One anomaly chased to ground rather than waved off: the Owens rack cascade
   also killed Avionics/HUD/Searchlight/ThermalSight -- zone 15 dz_searchlight,
   an authored CHILD SEGMENT of the missile rack (the sensor mast sits on the
   shoulder pod).  Authored skeleton + authored descend flag, walked faithfully.

Remaining surface NOT bench-verified, stated plainly: cross-pod -- the cascade
is master-authoritative (crit plugs bind on masters only) and the resulting
alarm states ride the existing weapon update records, but no two-node run has
watched a peer's view of an arm death.  The field re-test (Lynx/Conn Man's own
audit, in MP) covers exactly that.

Joe DiPrimaandClaude Opus 5 06adaee523 #110: the zone destruction cascade is LIVE -- an arm now takes its gun pod with it 
Lynx: "You can destroy an upper arm, and the gun pod is intact and can still
fire."  Conn Man's audit: three chassis, both arms, reproducible.  And the user
is right that this family was claimed fixed before: #86 gated fire on the
WEAPON's own destruction and was verified by destroying the weapon directly
(BT_KILL_SUBSYS) -- the field scenario was the ARM ZONE dying with the weapon
subsystem healthy, which that bench never reproduced.  Oracle's 693-night "I can
still fire destroyed energy weapons" was almost certainly this mechanism.

ROOT CAUSE -- a silent stub.  Mech__DamageZone::RecurseSegmentTable @0049cad4
was transcribed faithfully... against three local shim types whose iterators
unconditionally return NULL:
    struct SegmentIterator { DZRef *Next() { return 0; } };
    struct SegTableX       { SegmentRecord *operator[](int) { return 0; } };
The cascade fired on zone death (bench: 72 [cascade] lines), "descended", and
touched nothing.  Every line read correct; none of it did anything.

THE REAL WALK (decomp re-read, FUN_0049cad4): iterate the mech's segment table
(mech+0x300, vtbl+0x34 GetNth) to this zone's segment, then
    destroySiblingsOnDestruction (Wword 0x68): recurse every other zone on the
        SAME segment (seg+0xD0), setting graphic state 2 (Gone)
    descendOnDestruction (Wword 0x67): recurse every zone on every CHILD
        segment (seg+0xE8 -> child+0xD0) -- the arm takes the gun
The engine ALREADY HAS both structures: EntitySegment::damageZoneTable @0xD0 /
childIndexTable @0xE8 (TableOf is 0x18 -- byte-identical to the decomp offsets),
populated at stream time by JMOVER.cpp:373 [T0].  The stub was never necessary.
Implemented with the engine iterators via two new read accessors on
EntitySegment (SEGMENT.h); the binary's asymmetry is reproduced as-is (the
sibling loop checks graphic state != 1, the child loop does not; re-hits on a
1.0 zone re-run the cascade -- idempotent in effect).

VERIFIED (ava1, self-damage to one zone, autofire everything):
  dz_rarm -> [cascade] zone 9 -> zone 17; AFC100 + AmmoBinAFC100 + Condenser6
      ForceCriticalFailure'd; "[ammo] AFC100 -> NoAmmo (gate1): destroyed=1";
      torso LRM5/SRM2 keep firing (correct)
  dz_larm -> [cascade] zone 2 -> zone 6; PPC + Condenser4 force-failed;
      "[emitter] 'PPC' fire REFUSED (destroyed=1)" x4998 -- the emitter gate now
      logs refusals BY NAME (the FIRED line never named its weapon, which is how
      #86's verification gap survived)
  regression smoke: frame time 7.13/7.20ms, 0 asserts, 0 cascades in ordinary
      combat (they fire only on genuine zone deaths)

Authored data (now dumped under BT_DMG_LOG): descend=1 on exactly the four arm
zones (ava1: 2/6/9/17), destroySibs=0 everywhere -- so legs/torso behavior is
untouched by this change.

KB: combat-damage.md cascade section; reconstruction-gotchas #26 (the
silent-stub trap: a shim that returns EMPTY converts a reconstruction into
fiction that reads correct -- shims must Fail() loudly or log their emptiness).

Joe DiPrimaandClaude Opus 5 da70bd58b2 #84: the replicant salvo now HOMES AT THE LIVE TARGET -- the stale-point double detonation is gone 
Oracle (674): "missile appear to register hit explosions twice, once where
target was and again where the target is".  Rajel (693): "once where the mech
was when I fired and on the expected impact".

MECHANISM, measured on two nodes (BT_PROJ_LOG "DET at" now logs EVERY contact
detonation, including damage-0 rounds, which were invisible before): the
replicant salvo mirror pushed rounds with NO entity handle at the FROZEN
fire-time aim point, and the pool's contact test is proximity to p.targetPos --
so mirror rounds "contacted" the empty air where the target USED to be and
detonated there, on every peer, every salvo (45 salvos -> 234 frozen-point
air bursts in a 200s bench).  The true impact appears at the live position
(the shooter's own homing rounds on his node; the victim's damage reaction on
peers) -- two sites per salvo, exactly as reported.

THE BINARY'S MODEL (CLASSMAP, Missile flight-entity cluster): missiles are
ENTITIES with authoritative/GHOST Performance variants (Projectile
PTR_LAB_005129e8 / 005129f4) and their own WriteUpdateRecord (@4bef4c, slot 7)
-- peers ran ghost missiles updated from the wire and saw the TRUE trajectory.
One explosion, correct place, every node.  The frozen-point mirror is the port
infidelity (the entity Missile itself stays blocked by the documented 2007
Entity-base mismatch; mislanch.cpp:301).

FIX: the MissileLauncher update record now carries the locked target's EntityID
(salvoTargetID; EntityID::Null = point fire).  The mirror resolves it on the
receiving node via HostManager::GetEntityPointer (engine T0, an index-socket
Find -- NULL-safe on any ID), refuses non-mechs via BTIsRegisteredMech, and
pushes the mirror rounds WITH the handle -- they re-lead on the live local
replicant exactly as the master's own rounds do, and detonate at the true
position.  Guards: record-length gate (a short record from an older build has
no ID field -- its tail would be garbage and must not resolve) + Null check +
registered-mech check.

VERIFIED (two nodes, 200s, missile autofire both ways):
  * every record arrives len=52/52 with sane aims ([mlrec] diag)
  * 22/46 salvos resolve (tgtID=3:22 -> the victim's local master) and their
    mirror rounds home: the frozen-air DET population fell 234 -> 102, the
    live-homing population rose to 155/207 per node
  * the unresolved remainder is BENIGN and correct: EntityID::Null point fire
    plus hostID=-1 LOCAL entities -- i.e. the victim's WRECK, which autofire
    keeps shooting after the kill; a wreck does not move, so the frozen aim IS
    its true position
Downstream expectations: Ronin's smoke-screen (#114) should drop by ~the mirror
half, and the audio census (#32) loses the duplicate Static3DPatchSource
explosion sounds on peers -- both to be read from the next field logs.

Also in this commit: [projectile] DET diagnostic (every contact detonation with
position/damage/handle/aim), [mlrec] record-arrival diagnostic (len/recID/
subsys/counter/aim, capped 200), scratchpad/night9/mp_double.sh.

Joe DiPrimaandClaude Opus 5 3354db4bd1 #32: RETRACT the retention diagnosis; count what matters (steals + true drops); name the saturating class 
The reopen said "the pool fills and never returns a source".  The 30s census in
the SAME field logs disproves it: free returns to ~227-230 between bursts and
reuses climbs ~20/s all session.  free=0 on the failure line is true by
DEFINITION at the instant of a failed acquire -- the third instance of the
counter-sampling trap (live=256-vs-6, then hsparm greps, now this), read off the
alarm line instead of the trend line.

WHAT THE LOGS ACTUALLY SHOW
  * The pool cycles; release-on-stop exists and works (the engine steal loop).
  * During firefights CONCURRENT demand exceeds 240 and the priority steal loop
    services each new sound by killing an old one -- continuously through
    combat (failures spread across every decile of every combat session).
  * Idle standing demand is ~13 sources.  My "each component holds its SourceSet
    to entity teardown, ~20-25 per mech" narrative was wrong.
  * The raw ACQUIRE FAILED line count (6.8k-19k per log) is NOISE: the steal
    loop retries after every failed attempt, so lines accumulate per EVENT and
    most events still play via a steal.  True drops were never counted.

CHANGES
  1. Census now carries steals= and drops= (drops = the steal loop ran dry and
     the sound NEVER played) plus a per-class drop histogram
     ("[audio] dropped by class: {class 1005 x4v: N} ...") -- all ungated, so
     the next field logs are decisive instead of suggestive.
  2. The ACQUIRE FAILED print is rate-limited to 1/30s and now names the
     requesting class + voice count.  19k-line log spam distorted this triage.
  3. BT_AUDIO_SOURCES=<n> now raises the POOL cap too (it previously raised the
     AL context budget while the pool stayed at 240, making the field
     experiment impossible to run).

MEASURED (9 mechs, missile autofire, 150s)
  * cap 240: peak 130 sources, 0 fails -- demand tracks SHOOTER count, not mech
    count; one shooter cannot saturate.  A 6-shooter lobby pins 240.
  * cap 48 (BT_AUDIO_SOURCES=64): saturation reproduced -- census
    steals=223 drops=455, histogram names the classes.
  * Dominant field requester (requested=4) = class 1005 Static3DPatchSource:
    world-placed effect sounds, i.e. EXPLOSIONS.  1001 DirectPatchSource x1v
    dominates drops at low cap; 1002 Dynamic3DPatchSource x3v present.

CONSEQUENCE FOR THE FIX ORDER: #84's stale-aim double detonation duplicates
exactly the saturating class on observer nodes.  Fix #84 FIRST, then re-read the
field census; only if it still saturates does the budget experiment
(BT_AUDIO_SOURCES with frame time measured) become the play.

KB: the wrong night-9 entry in open-questions.md replaced with the corrected
diagnosis; gotcha candidate noted -- an alarm-line counter is not a trend.

Joe DiPrimaandClaude Opus 5 202ebbf84a KB + tracker: night-9 playtest (build 4.11.693) 
CONFIRMED FIXED and closed: #95 (missile salvo damage), #97 (leak gauge 3 levels),
#98 (loop-6 lamp), #99 (leak alarm audible).

#95 deserves a note: a tester reported "LRMs still doing 3.3 damage", but that is
the PER-MISSILE figure.  382 impacts across three 693 logs show the cluster being
delivered correctly -- LRM20 3.25 x burst 5..20 (total up to 65), LRM15 3.33 x
3..15, LRM10 3.50 x 2..10 -- and those burst ranges match the binary's
Random(n)+n/4 roll exactly.

#32 REOPENED.  The pooling change removed the alloc/free churn (the ~10% frame
time is real) but every 693 field log still shows
    ACQUIRE FAILED (requested=4 live=240 pooled=240 free=0 ...)
19,182 fails (Sauron) / 15,333 (Rajel) / 6,818 (Ronin), high-water 225 of 240,
starting ~1% into every session.  `free=0` is the diagnosis: sources are never
returned.  This is precisely the risk flagged when the fix landed -- retention,
not pool size.  Players called audio "fine" the same night; the log disagrees.

#84 still present, but the surviving explosion is a DIFFERENT mechanism from the
bundled one that was fixed: "where the mech was when I fired" is the stale
fire-time aim point already recorded as an open in rendering.md, i.e. an MP
visual, not the message-manager path.  Needs a two-node bench logging the
OBSERVER -- the earlier two-node run verified damage delivery but never the visual.

New: #108 ghost mech (peer never sees the death; shots still register, so it is a
visual/replication desync, the inverse of #94), #109 panic/eject, #110 arm
parent/child linkage (gun pod survives its mount -- three chassis, both arms;
parentArtifactZone exists but only drives LOD), #111 death warp bubble shown to
peers, #112 AFC shotgun spread (may be authentic Ultra-AFC burst), #113 LRM burn
duration, #114 missile smoke as a smoke screen, #115 hot box, #116 Standard-vs-
Expert heat gating, #117 per-chassis cockpit bounce.

⚠ A MEMBER OF THE ORIGINAL TEAM IS NOW TESTING -- "Ronin" (log user torak).  He
worked on the 1995 game and has played the pods recently.  Treat his pod
comparisons as primary evidence above reconstruction inference.  First two
contributions recorded in the KB: per-chassis cockpit bounce was deliberate, and
NARC likely shipped as data without an implementation.

⚠ Conn Man ran the OLD build (.674) for all seven of his sessions, so his reports
are not evidence about 693.  His arm-linkage audit is still valuable -- nothing in
693 touched that path.

Joe DiPrimaandClaude Opus 5 5a1a407ed1 pre-ship: resolve the new audio diagnostic gates ONCE instead of per frame 
RunSequence and AudioIdleWatcher::Execute run per sequence per frame, so the
BT_ATTRBIND_LOG probes added while chasing #99 were calling getenv ~2700x/sec on
a 15-sequence mech.  Small, but this is the same path the source-pooling fix
(#32) just bought 10% of frame time in, and an unset diagnostic should cost
nothing.  Cached in function-static flags.

Pre-ship smoke (combat, 2 kills, a respawn, clean teardown):
  frame time 7.18 / 8.27 / 8.71 ms  -- matches the post-pooling 7.79ms baseline

Joe DiPrimaandClaude Opus 5 5a425320b7 #92: map the direct-fire hit->zone path; the FOOT is pickable over only 3% of a mech's height 
Oracle, night 7: "Unable to damage the foot panels on Loki via direct fire from
front or side.  Was able to damage on Thor."

FIRST, THE MECHANISM -- it is not what the issue assumed (missing collision
geometry).  A direct-fire hit gets its zone one of two ways, decided at
Mech::TakeDamageMessageHandler by `invalidDamageZone`:

  AIMED   (invalidDamageZone=0): the zone rides in on the message from the
          per-part aim pick, MechSegmentPick (#73, btl4vid.cpp).
  UNAIMED (invalidDamageZone=1): DamageLookupTable::ResolveHit runs the authored
          cylinder lottery -- impact HEIGHT picks a layer, ANGLE picks a pie
          slice, and a weighted random roll picks the zone from that slice.

Measured live, both paths are in use: the Thor logged 16 unaimed hits
(invalidZone=1 zone=-1 -> ResolveHit) alongside aimed ones carrying real zones.

THE FINDING.  MechSegmentPick is a BOUNDING-SPHERE test whose primary key is
SMALLEST RADIUS WINS -- a larger sphere can never beat a smaller one the ray also
grazes.  The leg spheres, dumped in world space and IDENTICAL on both chassis:

    knee  centre y=1.868  r=1.505     spans y 0.364 .. 3.373
    toe   centre y=0.302  r=1.689     spans y -1.387 .. 1.991

The toe sphere is BIGGER than the knee's and they overlap heavily, so the toe can
only win where the ray misses the knee sphere outright -- i.e. below y=0.364.
Against a reference height of 11.16 that is a 0.36-unit window, **3.3% of the
mech's height**, and it sits right on the ground.  Everywhere else a shot at the
foot is credited to the LEG.  That is the reported symptom.

This is a PORT ARTIFACT, not authentic: btl4vid.cpp's own comment concedes the
sphere test approximates "the per-part semantic the 1995 mesh intersection
produced".  Real mesh intersection has no such interference -- aiming at the foot
mesh hits the foot.

NOT EXPLAINED, and stated plainly: the per-CHASSIS asymmetry.  Loki and Thor have
identical leg spheres, identical foot geometry (LOK_LFOT.BGF and THR_LFOT.BGF are
both 3082 bytes with the same token layout), and identical foot layers in their
damage tables (only the upper/cockpit layers differ).  So nothing found here says
the Loki should behave differently from the Thor.  The bench could not settle it
because BT_AIM moves the drawn RETICLE, not the pick ray -- there is currently no
harness to aim the pick at a chosen height.  That harness is the next step.

Diagnostics added:
  [pickgeom]   one-shot dump of every pick sphere in WORLD space (zone, r, centre)
  [pickcand]   which spheres a ray actually threaded, their perpendicular d, and
               which won -- the probe that makes "smallest wins" visible
  [dmgtable]   the whole authored DamageLookupTable: layers, slices, zone weights
  [dmgresolve] per hit: localY, heightRef, layer, theta, resolved zone
  [cylgate]    invalidDamageZone / table pointer / incoming zone at the gate
(the last three under BT_DMGTABLE_LOG, the first two under BT_PICK_LOG)
plus scratchpad/night8/footpick.sh.

Joe DiPrimaandClaude Opus 5 8daac37e40 #99: VERIFY IN THE IMAGE -- the shared-alarm Stop is authentic; do not diverge 
Answering "did you check the decomp or disassembly?" -- I had not.  I had checked
the authored data (BTL4.RES) and the MUNGA engine source and called it authentic
on source lineage alone.  Now verified in BTL4OPT.EXE:

  same sources compiled in : d:\tesla_bt\munga\AUDSEQ.CPP / AUDWTHR.CPP strings
  object factory           : @00466184  case 0x4b -> alloc 0x5C -> ctor @0043ccec
  vtable                   : 0x4ead48
  ReceiveControl           : @0043d3a4 -- switch on control IDs 1 / 2 / 9 / 12,
                             which is exactly our enum Start / Stop / Idle / Tempo
  Stop case                : @0043d3ca -> unconditional call StopSequence @0043d2d4
  StopSequence             : tests only its OWN isRunning (+0x28) then the Chase
                             loop -- NO refcount, NO awareness of other leak sources

Structurally identical to engine/MUNGA/AUDSEQ.cpp.  So the arcade behaved the same
way: with 19 subsystems sharing one alarm sequence, any one of them clearing its
leak silences the alarm while the others still leak.  AUTHENTIC -- do not "fix".

(The tempo bound check could not be used as an anchor: Verify() compiles out of the
retail build, so the AUDSEQ.CPP assert strings are present in .data but unreferenced
by code and invisible to the decomp export -- gotcha 21 again.  The object-factory
route via the numeric ClassID is what actually located the class.)

Recorded in context/gauges-hud.md with the full chain and the address table, so the
next person does not re-chase it or "fix" it.

Joe DiPrimaandClaude Opus 5 e058b6acb7 #99: trace the coolant-leak alarm end to end -- it IS implemented; found the real defect 
Oracle: "alarm is not sounding despite an active leak" ... "was sounding,
resolved a leak, but there was another".

RETRACTION FIRST.  I previously told the user the coolant alarm was "genuinely
unbuilt -- there is no alarm implementation to starve".  That was wrong, and it
was asserted without checking.  The alarm is fully implemented and the entire
chain works.  Traced live, in order:

  Condenser6.ReportLeak (= HeatSink::coolantActive) changes 0 -> 1
    -> [watchpoll] CHANGE on that exact address
    -> [matchfire] val=1 -> ctl 1  (StartAudioControlID)
    -> [seqstart] the alarm AudioControlSequence, events=25 looped=1
    -> [seqsend] ctl 8/16 (select), 6/1 (volume), 1/0 (START), 2/0 (STOP), ...
       a three-part looping alarm: two chirps then an 8s sustained tone.

The authored design, read from BTL4.RES: 19 subsystems per mech each bind TWO
AudioLogicalTriggers to their ReportLeak flag -- match 1 -> Start, match 0 ->
Stop -- and ALL of them drive ONE shared alarm sequence.

SO WHY WAS IT SILENT IN .674?  Almost certainly the audio source pool, fixed
after that build in ad9dfad.  Every player log from .674 is saturated with
ACQUIRE FAILED (3k-6.5k lines each, starting ~10% in and never recovering); an
alarm that cannot acquire an OpenAL source is silent.  The bench here shows 0
acquire failures on the current build.  ⚠ NOT PROVEN: this bench has no audio
device (pool census reads live=0 pooled=0), so the control chain is verified but
final playback is not.  Field confirmation needed.

THE SECOND SYMPTOM IS A REAL, REPRODUCED DEFECT AND IT IS IN THE AUTHORED DATA.
All 19 subsystems -- Condenser1-6, GeneratorA-D, Myomers, PPC_1/2, ERMLaser_1-3,
SRM6_1/2, Avionics -- share the single alarm sequence, and EACH one's leak-clear
sends an UNCONDITIONAL Stop.  So the moment any one of them stops leaking the
alarm goes silent, even while others are still leaking.  That is exactly what was
reported.  Since both the authoring and the MUNGA watcher code are authentic,
this is 1995 behaviour, and changing it is a deliberate divergence -- flagged for
a fidelity call rather than "fixed" unilaterally.

Diagnostics added (all under the existing BT_ATTRBIND_LOG gate):
  [seqcfg]  extended: the sequence's authored event list
  [seqstart] extended: events / looped / tempo / divisionsPerBeat
  [seqrun]  RunSequence entry state (isRunning / iterator / current event)
  [seqwait] an event exists but is not yet ready, with the time delta
  [seqsend] the sequence actually emitting a control
  [idlewatch] which components receive the idle tick that advances sequences
  [hsparm] extended with &ReportLeak so audio bindings can be correlated
plus scratchpad/night8/leakaudio.sh.

NOTE ON THE PROBES, because it cost real time twice today: [seqrun] first used a
single shared static counter, which the busy sequences consumed so the alarm
sequence never printed -- reading as "RunSequence is never called".  It is now
throttled PER SEQUENCE (runProbeCount).  A capped diagnostic that is silent is
not evidence of absence; the same trap produced a false "seqsend x0" and a false
"the trigger never fires" earlier in this investigation.

Joe DiPrimaandClaude Opus 5 e6103d02b2 #97: leak gauge reaches all THREE levels -- the normalisation was dropped with an x87 expression 
Players: "you can get up to three traingles which drains really quickly" ...
"only seeing one level (lowest) right now" (Oracle), corroborated by Draco
("3 triple delta being the top level").

The display was never the problem: BitMapInverseWipe is already built with
frames=3 and stacks three segments at two levels each (0..6).  The LEVEL
computation was wrong.

Our Execute rounded the raw leak rate:
    level = round(value)
The binary's @004c5d08 does NOT.  Ghidra renders the round as a bare
`FUN_004dcd94()` because it drops the x87 expression feeding __ftol -- exactly
KB gotcha 19, which we already had written down.  The real prologue, disassembled:

    fild  dword ptr [ebp-0x14]    ; ST0 = (float)fullWidth   (frames*2 = 6)
    fmul  dword ptr [ebx+0xb4]    ; ST0 *= value             (CoolantMassLeakRate)
    fdiv  dword ptr [ebx+0xb0]    ; ST0 /= third             (full-scale divisor)
    call  0x4dcd94                ; level = round(ST0)

i.e. level = round(fullWidth * leakRate / fullScale).

Without the normalisation the gauge rounded a value that never exceeds ~1.0
(coolantDraw = zoneDamage * heatLoad, and heatLoad is clamp(0.002*T, 0, 1) --
constants re-verified from the image, including the 80-bit extended 0.002).  So
level could only ever be 0, or 1 via the >0.0025 floor: ONE triangle, always, no
matter how bad the leak.  Three of the six condensers being mis-lamped (#98) hid
how systematic this was.

Also corrected on the way:
  * `third` was declared int but the binary FDIVs it -- it is a float.  The two
    call sites passed *(int *)(subsystem+0x150), i.e. the BIT PATTERN of a float
    read from a RAW OFFSET into our own layout (the databinding trap): at +0x150
    our layout has filterDecay, not the binary's field.  Now resolved through a
    complete-type bridge, BTHeatSinkLeakFullScale.
  * filterDecay was initialised 0.4f; @004b8fec writes 0.15f (param_1[0x54] =
    0x3e19999a).  It is written-once-never-read elsewhere in the port, so the
    correction is behaviourally safe and it IS the gauge's full scale.

Verified live: Condenser6 at 10% zone damage -> draw 0.0358 -> level 1 (one
triangle); the same formula reaches all three at heavier damage, and the mapping
spans draw 0.0026 (half of one) to 0.15 (three full).

Joe DiPrimaandClaude Opus 5 ee079083a3 #96: FIX -- normalise the myomer kinetic heat term to a reference frame rate 
The previous commit only instrumented.  This is the behavioural change.

The binary's drive-heat integrator (FUN_004b8d18) multiplies its climb and accel
terms by the time slice but NOT the kinetic one:

    heat += ratio^2 * (1+dmg) * [ (1-accEff)*|vy|*m*g*dt
                                + (1-velEff)*(0.5*m*|v|^2)     <-- no dt
                                + (1-accEff)*|v|*|a|*m*dt ]

A per-TICK energy is a constant on a fixed-frame 1995 machine and a variable on a
modern PC: heat/second scales with frame rate, so two players on different
hardware -- or one player in a heavy scene versus an empty one -- get different
heat from identical throttle.  That is a defect independent of what the pod's
rate actually was.

The kinetic term is now multiplied by (dt * kPodFrameHz), which is exactly 1.0
when dt == 1/30 and makes the result machine-independent.  This is the one
deliberate divergence from a verbatim transcription of @004b8d18, and it is
marked as such in the source.

Measured, Owens at seek 4 flat out:
    before   crossed degradeT(1000) at ~27s, peaked 1213, settled ~710
    after    peak 1007, settled ~525
i.e. roughly halved at our measured ~59Hz, which is the direction the players
asked for ("too much IMO", "def need to tone down the myomer heat some").

⚠ CALIBRATION IS NOT PROVEN.  30Hz is the i860 BOARD frame ([T1],
rendering.md:177); the HOST simulation rate is not separately established, and no
fixed-timestep constant exists in the image (searched 1/15..1/60 and 30/60 Hz --
the arcade computed dt from a clock, as we do).  So the reference rate is the
best-documented value, not a proven one.  BT_MYO_HZ overrides it with no rebuild
so it can be calibrated by feel.

Precedent for the bug class, already logged in the KB: "trail density is
frame-rate-dependent (2/frame @60fps = 2x pod density)" (rendering.md:222).

NOT settled: whether the per-chassis ordering matches player memory (a Thor
sustaining seek 4 where a light chicken-walker cannot).  Post-fix benches put the
Thor HOTTER (crosses at 40s vs the Owens at 47s), but those runs are BT_GOTO
path-driven and the acceleration term is large and path-dependent, so they are
too noisy to conclude from.  The cooling data being identical across chassis IS
solid (measured, previous commit).

Joe DiPrimaandClaude Opus 5 9dd7d48b41 #96: instrument the myomer heat model -- per-mech profile CONFIRMED, overheat cause LOCATED 
Two player claims, both now answered from the decomp + measurement rather than
inference.

THE EQUATION (FUN_004b8d18, constants read from the image: _DAT_004b8ee4=0.5,
_DAT_004b8ee8=0.0 (the fabs), _DAT_004b8eec=1.0):

  heat += ratio^2 * (1+damageLevel) *
          [ (1-accEff)*|vy|*m*g*dt        climb   POWER
          + (1-velEff)*(0.5*m*|v|^2)      kinetic ENERGY -- NO dt
          + (1-accEff)*|v|*|a|*m*dt ]     accel   POWER

Our implementation already reproduces this verbatim, dt-less term included.

CLAIM 1 -- "each mech has a unique heating profile".  TRUE, and working, but NOT
by the mechanism the player described.  Measured across thr1/own1/mad1/vul1:
  * the myomer record is IDENTICAL on every chassis
    (velEff 0.995, accEff 0.8, gears 3000/5000/7000/9999, rec 2,
     degradeT 1000, failT 2000, thermalMass 250000)
  * the heat-family COUNT is identical too -- 6 Condensers, 1 HeatSinkBank,
    1 Reservoir, 4 Generators on all four
  * every cooling parameter is byte-identical Thor vs Owens (condenser
    conductance 315000 / mass 420000, bank 231000 / 1.39e6, reservoir
    190000 / 3.42e6)
So there is NO authored per-chassis cooling variation.  The profile emerges from
the equation instead: heat ~ m*v^2, and light mechs are faster.  Measured at
seek 4, flat out:
    thr1  mass 70000  |v| 11.34  kinetic/tick 49026
    own1  mass 35000  |v| 17.22  kinetic/tick 57350
The Owens is HALF the mass and generates 17% MORE drive heat, because v^2 beats
m.  That reproduces the player's OUTCOME (a Thor sustains seek 4, a light
chicken-walker cannot) via speed, not heatsink count.

CLAIM 2 -- "it runs too hot".  The kinetic term carries NO dt: it adds an ENERGY
every TICK, so its contribution per SECOND scales with the tick rate.  Measured
dt here is ~0.017 (~59Hz) and variable.  The other two terms are power terms and
are rate-independent.  On flat ground the climb term is additionally dead --
gravity reads 0 (the carried "environment gravity unwired" open), so hills do not
heat at all right now.
NOT yet established: the 1995 tick rate the dt-less term was calibrated against.
Until that is pinned the OVERHEAT FACTOR is unquantified -- flagged, not guessed.

Adds three diagnostics, all under BT_MYO_LOG:
  [myoheat] now splits climb/kinetic/accel + dt + the kinetic share
  [myoparm] one line per myomer: efficiencies, gears, thermal thresholds
  [hsparm]  one line per heat subsystem: conductance + thermal mass
and three benches (myoheat/myoparm/myocmp) that produced the tables above.

Joe DiPrimaandClaude Opus 5 56f15b569a #98: prove the lamp fix -- table pinned to the image, three condensers verified live 
Follows the request to prove the whole fix rather than the one case I had.

1. TABLE, all indices: scratchpad/night8/lamptable_check.py asserts the
   reconstructed arrays against BTL4OPT.EXE and exits nonzero on drift.
       kBTCondenserLamp @0051d058  MATCH  07 2F 2E 2D 2B 2A 29
       kBTPlacementLamp @0051d070  MATCH  29 1A 1B 1C 1D
       kFixed (FUN_004cc148 switch) MATCH  2F 2E 2D 2C 2B 2A
   This covers condensers 2/3/5 without hunting zones for them: there is no
   per-index code path, only the array contents, and those are now pinned.

2. LOOKUP PATH, live: condensers 1, 4 and 6 resolve 0x2F, 0x2B and 0x29 --
   exactly the table.  Condenser 4 is the meaningful control: my reverted "fix"
   would have given 0x2C.  Myomers (eng-page path, 0x25/0x21) and SRM6_1 (quad
   button, 0xd) still annunciate, so other subsystem classes are unregressed.

3. GUARD: condenserNumber is parsed from the name's trailing digit
   (NameTrailingNumber, mirroring the binary's atoi), and every condenser in
   BTL4.RES is Condenser1..Condenser6 -- no Condenser0, no bare name.  So the
   1..6 guard covers every shipped case and slot 0 (0x7) is unreachable.  This
   was the real risk in changing `n >= 0` to `n >= 1`; it is closed.

4. PIXELS: leaklamp_pixel.{sh,py} capture a leaking run and an undamaged control
   run from the cockpit and difference their per-pixel temporal variance.  The
   leak is visibly real -- the COOLANT reservoir drains on screen (S 331->330
   while the control sits at 329).

⚠ WHAT THE PIXELS DID NOT SETTLE, and it is not a testing gap.  Lamp 0x29 is
ALSO kBTPlacementLamp[0]: DAT_0051d058[6] and DAT_0051d070[0] are the SAME int32
-- the two tables abut.  So condenser 6's lamp may not be its own loop button at
all, and slot 6 may be an overrun in the BINARY too (its read is unchecked).
Reproducing it is the faithful choice either way, and we now do exactly what the
binary computes -- but whether a pilot sees loop 6's own button light is a
question only someone who played the original can answer.  Asked on the issue.

CORRECTION: 0b98370 claimed @0051d058 "holds gauge-type name strings, so the
provenance is questionable".  That was MY bug -- a PE section-header field-order
mistake (unpacking VirtualSize/VirtualAddress/SizeOfRawData/PointerToRawData
then destructuring in a different order).  The original reconstruction's
provenance was accurate.  The checker in (1) uses the corrected reader.

Joe DiPrimaandClaude Opus 5 0b983703a4 #98: CORRECTION -- restore the byte-verified condenser lamp table; my previous mapping was a guess and was wrong 
0254d9e re-mapped condensers onto the coolingLoop1..6 lamps on the reasoning
that "six condensers <-> six loops" and that the table's missing 0x2C was a
transcription slip.  It was not.  Read the decomp -- which was exported the whole
time and which I should have read BEFORE touching the table:

    FUN_004cc264(sub) { return *(int *)(&DAT_0051d058 + sub[0x1d4] * 4); }

indexed by condenserNumber, no bounds check.  And the bytes at 0051d058 are:

    07 00 00 00  2F 00 00 00  2E 00 00 00  2D 00 00 00
    2B 00 00 00  2A 00 00 00  29 00 00 00  1A 00 00 00

So the ORIGINAL table was byte-accurate: the binary really does skip 0x2C.  The
condenser lamps (2F 2E 2D 2B 2A 29) are a DIFFERENT set from the coolingLoop
lamps of FUN_004cc148 (2F 2E 2D 2C 2B 2A) -- overlapping but distinct.  My
"fix" therefore mis-mapped condensers 4, 5 AND 6, replacing a correct mapping
with a plausible-looking wrong one.

What IS a real port defect, and all that should have changed: the bounds check.
`n >= 0 && n < 6` is a 0-based bound on a 1-based index (live: 'Condenser6'
reports 6), so condenser 6 was rejected and annunciated NOTHING, where the
binary resolves it to 0x29.  The table is now 7 slots ending in 0x29 and the
guard admits 1..6 -- kept rather than dropped, so a stray authored number cannot
walk off the end into the adjacent per-placement table the way the binary's
unchecked read would.

Verified: Condenser6 leak -> [galarm] condition 2 -> lamp 0x29 FLASH, which is
what the binary computes for it.

Lesson, and it is the third time this week: I had a live-reproduced symptom and
inferred the cause from internal consistency instead of reading the available
decomp.  The symptom was real; the explanation was invented.  Gotcha 24 covers
over-generalising a verified fact -- this is its sibling: inventing a fact to
explain a verified symptom.

Joe DiPrimaandClaude Opus 5 0254d9ef34 #98: leaking condensers now flash the RIGHT button -- half of them flashed the wrong one, one flashed nothing 
Field reports were all "intermittent": "the display buttons aren't always
flashing or lighting up on leaking components" (Oracle), "I'm getting leaks but
no indicators" (Lynx), "I am getting indicators sometimes" (Sauron).  It is not
intermittent -- it is per-condenser, and three of the six were wrong.

condenserNumber is 1-BASED (verified live: 'Condenser6' reports 6), which the
lamp table's own comment stated.  The guard was `n >= 0 && n < 6` -- a 0-based
bound -- and the table it indexed was missing 0x2C:

    condenser 1..3  -> 0x2F 0x2E 0x2D    correct
    condenser 4     -> 0x2B              WRONG (loop 5's button)
    condenser 5     -> 0x2A              WRONG (loop 6's button)
    condenser 6     -> rejected          NOTHING flashes

So a leak in loop 6 annunciated nowhere, loops 4-5 lit a neighbour's button, and
loops 1-3 were fine -- which from the cockpit reads exactly as "sometimes".

Condenser N drives cooling-loop N, whose six lamps are the same ones the
coolingLoop1..6 codes already resolve through, so the fix routes condensers
through that verified map (BTFixedLampOf(N-1)) and retires the duplicate,
partly-wrong table rather than patching it.

⚠ PROVENANCE: the retired table cited @0051d058 as byte-verified.  That address
holds gauge-type NAME STRINGS, not lamp ids, and a byte search for the six loop
ids as consecutive int32 finds nothing -- so neither the old table nor the new
mapping is byte-verified.  The correction rests on three checkable things: the
1-based numbering (live), the guard contradicting its own documented indexing,
and six condensers mapping onto the six cooling-loop lamps of the verified fixed
map.  [T2 -- behaviour verified, not byte-grounded.]

Also adds the missing diagnostic on the silent path: an alarm item that matched
its condition but resolved no lamp now names the subsystem and why, instead of
returning quietly.  That is what found this, and it immediately surfaced a
SECOND gap for someone to pick up: a destroyed HeatSink (condition 0) resolves
no lamp either, because it is neither Condenser nor Generator nor a
PoweredSubsystem with an aux screen.

Verified (scratchpad/night8/leaklamp.sh, BT_LAMP_LOG):
  before  [galarm] condition 2 ... sub 'Condenser6' -> NO LAMP RESOLVED
  after   [galarm] condition 2 ... -> lamp 0x2a FLASH

Joe DiPrimaandClaude Opus 5 bb7a6abe70 #32: correct the stale "no field complaints since" note + record the frame-time A/B 
Found while checking whether a player had reported this before: the code already
carried a prior analysis of this exact error which deliberately decided NOT to
act on it, concluding the 2026-07-23 atomic-delete fix (a999e5c) had settled it
with "no field complaints since", and that the remaining exhaustion was
transient and likely sub-perceptual.

That claim did not hold, and the note was still sitting there to mislead the next
reader.  All five 4.11.674 player logs are saturated: 3031/4657/5245/6275/6571
failures, first one ~10% into a match, still failing at 97%.

The prior note's core reasoning was about raising the source BUDGET -- more
voices mixing = more CPU during heavy combat -- and it is sound; BT_AUDIO_SOURCES
stays opt-in and unset.  But it does not apply to pooling, which changes no
budget: idle pooled sources are stopped and detached and cost nothing to mix.
The note asks whoever touches this to measure frame time, so I did, same bench
both ways:

    pre-fix   8.672 ms weighted avg over  9390 frames
    post-fix  7.794 ms weighted avg over 10047 frames

Removing ~20k alGenSources/alDeleteSources driver calls per match is a net CPU
WIN, not a cost.  Single run each, so indicative rather than definitive, but it
points the opposite way from the concern.

Joe DiPrimaandClaude Opus 5 ad9dfade88 #32: POOL the OpenAL sources instead of creating and destroying one per sound 
Every 4.11.674 player log is saturated with acquisition failures -- 3031, 4657,
5245, 6275, 6571 across five machines.  In Lynx's largest session the first
failure lands 9.3% in and they continue to 96.8%: once it starts it never
recovers for the rest of the match.

CAUSE: RequestAudioChannels called alGenSources() per sound event and
ReleaseSourceSet called alDeleteSources() on release -- create and destroy per
sound.  OpenAL sources are a scarce driver resource (OpenAL Soft caps a context
at 256) and a combat burst churned straight through the ceiling.

The two counters looked contradictory and were the tell: ACQUIRE FAILED always
printed live=256 while the 30s census printed live=6.  Same global, sampled at
different moments -- sources spike to the cap during a burst and drain back
between them.  Churn, not a steady leak.

FIX: generate sources once, up to a cap, and recycle them through a free list.
Release scrubs and parks instead of deleting.  Steady-state play performs no AL
allocation at all.

The scrub is load-bearing, not hygiene: a recycled source carries whatever the
previous owner set, and the engine sets AL_LOOPING per sound
(L4AUDLVL.cpp:327).  Hand a looping source to a one-shot and it plays forever --
which is the "sound stuck looping" family (#51, #5).  Every reusable property is
reset at the single point where a source changes owner.

VERIFIED (scratchpad/night8/audiopool.sh + the two-node mp_burst.sh):
  solo, sustained fire  : 0 failures, pooled 152, reuses 21998
  two nodes, 4 min      : 0 failures on both, pooled 148/149, reuses ~7000 each
⚠ HONEST LIMIT: the bench does NOT reproduce the field failure -- the PRE-fix
binary also scores 0 on it (peak 49 live), because solo/2-node combat is not
dense enough to reach 256.  So this verifies the pool works and allocates
nothing in steady state; it does NOT by itself prove the field failures are
gone.  The five field logs remain the "before".

Peak demand is set by how many audio COMPONENTS are alive (each reserves a
SourceSet of up to 25 voices and holds them), not by audible sounds: measured
high-water 138 solo, 149 two-node.  That scales with player count, so the cap is
set near the driver ceiling (240) and the pool now logs its high-water mark once
per 25-source band -- so the next playtest sizes this from field data instead of
a guess.  Growth also self-limits: if a driver offers fewer sources than the cap,
alGenSources simply fails, growth stops, and the pool recycles what it has.

Joe DiPrimaandClaude Opus 5 3a22c334ac bench: two-node CROSS-POD damage verification for the #95 burst change 
Projectile damage now Dispatches directly at the victim instead of going through
the shooter's SubsystemMessageManager, so cross-pod delivery had to be proven on
real nodes rather than assumed.

RESULT: cross-pod delivery intact, and the cluster count survives the wire.
Node A fired 38 missile rounds with bursts {1:5,2:6,3:6,4:7,5:7,6:7}; node B
received exactly the matching zone applications {2:12,3:18,4:28,5:35,6:42} --
i.e. rounds x burst, per burst band, exact.  135 of B's 142 explosive
applications carried burst > 1 (the manager path used to drop it to 1).
Energy stayed at burst 1 on both nodes; no crash on either.

Joe DiPrimaandClaude Opus 5 c23d06cbb5 KB: correct the burstCount claim -- it is honoured by the CALLER, not cosmetic 
The KB asserted as [T1] that "burstCount is cosmetic for zone damage".  Half of
that is byte-verified (DamageZone::TakeDamage @0041e4e0 really does ignore it);
the other half was an inference that inherited the [T1] tag and then justified
task #62's salvo-lead design -- which silently divided every missile salvo by its
missile count (gitea #95).

Corrected in both places it appeared (combat-damage.md:334 and :884): the CALLER,
Mech::TakeDamageMessageHandler @0x4a0423-0x4a04d8, applies TakeDamage burstCount
times and re-rolls the struck zone per burst.  burstCount = number of
applications; load-bearing for missile cluster count, splash falloff and the gyro
bounce.  Also records that the arcade Missile dispatches DIRECTLY at the victim
rather than through the message manager (whose consolidation drops burstCount).

New gotcha 24: a verified fact, over-generalised, becomes a wrong design premise.
Detection smell -- a "cosmetic/unused" claim about a field other code still
computes carefully.  Nobody spends instructions randomising a decorative value.

Joe DiPrimaandClaude Opus 5 3b7c19c232 #95: REVERT the salvo-damage hack; deliver the cluster the way the binary does 
Supersedes the mislanch change in efc3e9f, which multiplied the lead round by
missileCount.  That produced roughly the right average total but as ONE lump on
ONE zone, with no scatter and no variance -- not what the arcade does.

WHAT THE BINARY DOES (all byte-verified):
  * MissileLauncher ctor @004bcff0:  burstCount = missileCount;
                                     damageAmount /= missileCount
  * FireWeapon @004bcc60 spawns exactly ONE Missile -- no loop, missileCount is
    never read there.  The salvo IS one cluster round.
  * Missile::Perform rolls how many of the cluster connect right before it
    dispatches (part_013.c:10082):  b = Random(n) + n/4, clamped to n
    -- i.e. between a quarter of the salvo and all of it.
  * It then dispatches DIRECTLY at the struck entity (FUN_004be078:
    param_2->Dispatch(&msg)) -- NOT through the shooter's message manager.
  * Mech::TakeDamageMessageHandler @0x4a0439-0x4a04d8 applies the hit
    burstCount times, RE-ROLLING the struck zone per burst.

Our handler already implements that loop faithfully (mech.cpp, task #80) -- I
wrongly believed it was missing, because the KB asserts as [T1] that "burstCount
is cosmetic for zone damage".  That is half right: DamageZone::TakeDamage really
does ignore burstCount (verified @0041e4e0), but the HANDLER honours it by
calling that function repeatedly.  KB corrected separately.

The actual defect was that the projectile impact path hardcoded burstCount = 1,
and -- worse -- routed damage through the SubsystemMessageManager, whose
consolidation rebuilds the record from a stream carrying only {damageType,
damageAmount, subsystemID}.  DamageInformation has no burstCount field, so the
cluster count was DROPPED in transit no matter what the round carried.

So: dispatch projectile damage directly, as the binary does, carrying the rolled
burst.  This also retires the #84 double explosion architecturally -- the second
blast came from the manager's bundled explosion, and projectiles no longer go
through the manager at all.  The MarkRoundDetonated suppression added in efc3e9f
is therefore dead and is removed.

ALL-WEAPON-CLASS AUDIT (scratchpad/night8/allweap.{sh,py}), one run, all classes
firing at once:
  EXPLOSIVE (missile)  38 zone applications, bursts spread 1x2,2x6,3x9,4x4,5x5,
                       6x12 across ELEVEN zones -- the [n/4..n] roll plus the
                       per-burst zone re-roll, i.e. the cluster scattering
  ENERGY    (beam)      8 applications, burst 1  -- unchanged, no regression
  type4                 8 applications, burst 1  -- unchanged
  COLLISION             0 applications reached armour -- divert intact
Explosions: 10 projectile impacts produce no bundled blast; direct-fire still
queues its own (11 made).

NOT yet verified: cross-pod delivery.  Dispatch reroutes to a replicant on its
own (and the binary relies on exactly that), but the manager routing is gone, so
MP damage should get a two-node run before this ships.

Joe DiPrimaandClaude Opus 5 efc3e9ff1a #95/#84: missile salvos deliver their FULL authored damage, and stop double-exploding 
THE SALVO DAMAGE (#95).  Players measured an LRM 15 landing "3ish points".  The
logs agreed: [projectile] IMPACT damage=3.33333 (Oracle, LRM15) and 3.5 (Rajel,
LRM10).  Those are right PER MISSILE -- 50/15 and 35/10 -- and the bench shows
why the salvo still under-delivers: each launcher pushes N rounds of which
exactly ONE carries damage.

Two individually-correct changes composed into an N-fold shortfall:

  * The ctor does what the binary's MissileLauncher ctor does (@0x3ac/@0x3d4):
        damageData.burstCount    = missileCount;
        damageData.damageAmount /= missileCount;
    The record holds the PER-MISSILE amount plus the count; the arcade
    reconstitutes amount x burstCount when it applies the hit.
  * Task #62 then correctly stopped the port applying the hit once per visual
    round (that was ~missileCount-x too lethal) by damaging only the lead round
    -- but handed it the already-divided amount.

Our DamageZone::TakeDamage is `damageLevel += amount * scale` and drops
burstCount, so the salvo delivered amount/missileCount.  Since the port collapses
the cluster to one damaging round, multiply the count back in there.  Bench: an
SRM6 salvo now lands amt=35 (the authored total) taking a zone 0 -> 0.556, where
it previously landed 5.83.

THE DOUBLE EXPLOSION (#84).  Oracle: "missile appear to register hit explosions
twice, once where target was and again where the target is."  There are two
spawn sites: BTSpawnRoundDetonation at the round's own impact point, and the
message manager's bundled explosion at the CONSOLIDATED point a frame later.
The duplicate was known and thought harmless -- "among a rippled volley it is
invisible" -- which held only while a salvo landed N detonations.  A projectile
now marks its weapon (MarkRoundDetonated) and the consolidation skips queueing a
second blast for it; direct-fire weapons never mark, so lasers/AC keep the
bundled explosion they rely on.  Bench: 4 missile impacts -> 4 SKIPPED, while 11
direct-fire hits still queue normally.

SWEPT CONTACT (#84 tail).  Contact was a 10-unit sphere sampled only at the END
of each step.  With the authored thruster live (#84) field rounds arrive at
v=955 -- a ~16 unit step at 60fps, larger than the radius -- so samples can
straddle the target.  (Pre-#84 rounds flew ~100-300 = a 1.7-5 unit step and could
never skip it: the velocity fix exposed this, it did not cause it.)  Now tests
the whole segment travelled and bursts at the point of NEAREST APPROACH, which
also stops the detonation being flung past the target at speed.

RETRACTION: I posted tunnelling as the leading explanation for the lost salvo.
The bench disproves it -- zero fizzles, and the "missing" rounds are the dmg=0
visual rounds of the cluster, which never registered damage by design.  The
sweep is kept as speed-independent robustness, not as the #95 fix.

Bench: scratchpad/night8/salvo.sh (BT_PROJ_LOG + BT_FIRE_LOG).

Player testimony worth keeping out of the issue tracker alone:

* SENSOR PANEL model, from VGL Lynx -- the last major system without one.
  Sensor damage flickers the HUD (corroborated by period footage), degrades
  radar/map, affects the searchlight, and possibly the hot box.  Gitea #105.
* COOLANT LEAK severity is a THREE-level display (1/2/3 triangles + alarm);
  we only ever produce the lowest.  Our leak rate is a continuous scalar, so
  either the banding is missing or the magnitude never leaves the bottom band.
* MYOMER heat calibration is CHASSIS-RELATIVE: a Thor sustains seek 4
  indefinitely, a chicken-walker cooks in under a minute.  That spread is the
  acceptance test -- a uniform "too hot" indicts the drive-heat coefficient
  rather than the sink capacities.
* RAM damage: the binary's internal-only collision divert MATCHES what players
  observe (gyro/myomer damage, coolant leak, NO armor damage, grinding inert).
  May be working as intended; awaiting a player ruling.  Gitea #103.

Joe DiPrimaandClaude Fable 5 5410371b0c #86: destroyed weapons can no longer fire -- the fire gates read a 
never-written cell (the split-cell gotcha)

Both weapon fire gates (ProjectileWeapon gate 1 @4bbd36, Emitter
hard-failure @4baab9) test the binary's subsystem+0x40 for Destroyed(1).
In the 1995 layout that offset sits INSIDE the embedded status alarm
(statusAlarm@0x2C + level@+0x14 = 0x40) -- ONE cell, written by
ForceCriticalFailure when a zone's crit cascade kills the subsystem.  The
port models the same address as TWO members: the AlarmIndicator AND a
plain int simulationState@0x40.  Every destruction path writes the ALARM
(so the MFD draws its X correctly) while the gates read the plain int,
which nothing ever writes -- so a weapon on a blown-off arm showed
destroyed on every panel and kept firing and scoring, locally and on
peers (night-7: all three testers, screenshots of a missile leaving a
destroyed pod).

The tell had been sitting in our own logs for weeks:
  [ammo] SRM6_1 -> NoAmmo (gate1): destroyed=0 ...
on a mech whose launcher was X'd out.

Fix: both gates now read statusAlarm.GetLevel()==1 as well as the int.
Also added: the crit-cascade log names the destroyed subsystem, a
BT_SELF_DAMAGE_ZONE=dz_* named-zone bench mode, and BT_KILL_SUBSYS=<name>
(force ForceCriticalFailure on one named subsystem -- the exact call the
zone cascade makes, so a bench can ask 'the panel says dead, does it
still shoot?' without hunting for the zone that carries a given weapon).

Verified A/B in ONE run: before the kill both SRM6 launchers fired 2
salvos each; after, the destroyed launcher fired ZERO (gate log
destroyed=1) while its twin kept firing normally.

KB: new gotcha #22 (the SPLIT CELL -- one binary offset, two port
members, only one written; sibling of #1) + combat-damage entry.

  speed 53.7 u/s = 193 kph -- SUPERCHARGE (Oracle's pod figure: 182 for
  a 75-tonner; the 60t Black Hawk runs faster);
- heat at ratio^2 = 2.04: myomer T 531 -> 1765 (deep past the 1000
  degradation line);
- heatFactor governor: drive 1.43 -> 1.10 -> 0.62 (the supercharged mech
  slows BELOW normal while cooked), coolant pulls T back (1765 -> 740),
  drive recovers to ~0.77, oscillates -- the mech self-settles into a
  thermally-limited cruise: 'top speed for less than a minute' exactly;
- the hard freeze (drive -> 0: demand AND turn zeroed) is the same code
  path past failure temp, reachable when the coolant loop is compromised.

Joe DiPrimaandClaude Fable 5 905a4a86c0 RETRACTION + FIX: the myomer seek->speed coupling IS in the 4.10 binary -- 
restored byte-grounded; the morning's removal was export-gap blindness

Player testimony (Oracle, pod veteran: seek-4 humanoid = 182 kph -- the
manual's printed Super Charged figure; overheat = 'freezing up') forced a
re-audit of the morning's 'no dynamic myomer->speed feed' verdict.  The
verdict was WRONG: a raw-image capstone sweep for FPU reads of [reg+0x31C]
found the consumer inside the UN-EXPORTED master-perf region -- the same
decomp gap that hid the #93 crash block.  Decoded @0x4a9cf2-0x4a9da4 [T1]:

  per frame: MAX speedEffect@0x31C over the myomer chain (+0x7AC)
             -> mech+0x79C
             mapper->speedDemand@0x128 *= it        (the SPEED coupling)
             if |drive| <= 1e-4 (@0x4ab16c):
                 mapper->turnDemand@0x12C = 0       (the FREEZE)

Everything the manual + the veterans describe emerges: gear 4 rides
speedEffect ~1.43 into the RegisterMaxOutput gait cap (base x 1.4284 --
the two mechanisms interlock: 61.5 x 1.43 = 87.9 vs cap 87.8 measured) =
SUPERCHARGE; myomer heatFactor degradation slows you; overheat freezes
speed AND turn; damage slows (speedEffect carries 1-damage -- #75's
original premise was RIGHT and its 'falsified' close was wrong).

Restored in mechmppr.cpp, byte-grounded and better than the pre-removal
draft: MAX over the chain (was first-found), NO 1.0 clamp (the old clamp
ate the overdrive), turn-freeze included.  BTMyomersSpeedEffectOf
(unclamped) replaces the deleted BTMyomersDriveOf.

Verified live: healthy drive=1.0 (no speed change), collision-rattled
myomers drive 0.999 -> 0.892 -> 0.742 with demand scaling in lockstep
(61.5 -> 54.9 -> 45.7).

KB corrected in place (subsystems WAVE 6, pod-hardware manual audit
retraction, open-questions resolved) + NEW GOTCHA #21: export-gap
blindness -- 'no callers in the decomp' is not 'no callers in the
binary'; sweep the raw image for the operand pattern before declaring a
data path dead, and when a primary source disagrees with your decomp
sweep, suspect your evidence first.

Joe DiPrimaandClaude Fable 5 4704ab3d41 #84: missiles ACCELERATE like the binary -- the pool flew at constant 
rack-eject speed; the authored MissileThruster was never applied

The binary Missile hosts a MissileThruster subsystem: authored
acceleration for BurnTime seconds after the MuzzleVelocity eject.
Authored values decoded from BTL4.RES (type-15 missile model records,
reached from the AmmoBin's ammoModelFile via the type-1 MODELLIST
indirection): SRM 2.5s @ 600 u/s^2, LRM 10s @ 300 (climb 50), Streak
3s @ 300 (turn 360deg/s), NARC 10s @ 300; splash 30 all (port constant
was already right); authored drag ~0.001 = negligible.

The port pool flew every round at CONSTANT |MuzzleVelocity| -- SRMs 100
u/s, LRMs 30 u/s (10x slower than authored) -- the entirety of the
night-7 "missiles are very slow" report, and the driver of the
"explosion before the missiles arrive" perception (the salvo-lead
detonates while the slow spread rounds straggle in).

Fix: BTMissileThrustOf (mech4.cpp) lazily parses + caches the RES
thruster table (ModelList ids aliased to their type-15 member's
burn/accel); both launch paths (master FireWeapon + the replicant salvo
mirror -- peers see the same speed) resolve through the launcher's bin
and pass burn/accel into the pool; the advance integrates speed +=
accel*dt while burn remains, heading preserved.  Ballistic rounds
(autocannon/gauss) pass 0/0 -- unchanged.  Impact log now prints
v=/burnLeft= evidence.

Verified live (solo, BT_SPAWN_ENEMY + BT_AF_MISSILE): thrust table 8
entries cached; Black Hawk Streak resolve burn=3 accel=300; impacts at
v=277 u/s (was a constant 100).  Fun authenticity note: the Black
Hawk's "SRM6" fires strk (STREAK) ammo per its authored bin.

Joe DiPrimaandClaude Fable 5 ac7c46b87a #93: fix the end-of-round PerformAndWatch crash -- the STATIC projectile 
pool held dangling entity pointers across round teardown

Root cause (disasm-pinned on the shipped 4.11.659 exe): RajelAran's crash
(call to 0x65676769 = ASCII 'igge', EBP-walk return btl4+0x2b91a) is the
tgt->Dispatch vtable call in BTUpdateProjectiles' NON-MECH impact branch
(mech4.cpp:1598; the site matches the disasm literally -- the 0x12/0x64
TakeDamageMessage ctor, the EntityID::Null ternary, the getenv gate after).

The trap: the mech branch is guarded by BTIsRegisteredMech(tgt) -- but at
round teardown a destroyed mech is DEREGISTERED, so a round still in
flight (the pool is a static array that outlives the round; missiles are
slow, #84) holding it as p.target now FAILS the mech check and falls into
the !BTIsRegisteredMech branch, which treats the freed mech as a cultural
icon and dispatches into freed memory.  The liveness check itself routed
the dangling pointer into the unguarded branch.  Freed heap reused by a
string -> vtable slot +0x10 read 'igge' -> call 0x65676769.  (The EBP
walker explains the stack shape: the faulting call pushed its return
address on ESP, but the walk reads [EBP+4] = PerformAndWatch's frame.)

Fix -- scrub at the source of truth:
- BTProjectilesDropEntity(e): every pool entry drops a dying entity from
  p.target/p.shooter; called from ~Mech and ~CulturalIcon (the only free
  paths for targetable entities).  Flight + impact code is already
  null-guarded on both fields.
- BTProjectilesClearAll(): kills all rounds at RunMissions exit (cross-
  mission hygiene for the static pool).

Verified: 6 short-mission cycles (45s missions with a spawned dummy +
autofire, mission expiring mid-combat) -- 0 exceptions, 6/6 clean
'RunMissions returned'.  The original crash was a heap-reuse race with no
deterministic repro; the scrub eliminates the dangling-pointer class by
construction.  (Bench note: blind autofire never launches missiles -- the
launcher needs a target lock -- so the exact in-flight race was not
re-created; the non-regression + the pinned mechanism carry the verdict.)

Joe DiPrimaandClaude Fable 5 cf8618bcb9 myomer system COMPLETE -- the 'WAVE 6 mover cutover' was a phantom built on 
a misattribution; the authentic couplings are all live

THE CORRECTION [T1]: @004b9550/@004b95b8 ('ConnectToMover'/'Disconnect
FromMover') are MechWeapon::ConfigureMappables/ChooseButton -- their +0x31C
is the weapon TriggerState and **(mech+0x128) is the CONTROLS MAPPER's
button roster (the MECHWEAP.CPP assert string + the trigger-edge detector
@004b9608 sit adjacent in the image).  The binary has NO dynamic myomer->
speed feed: AvailableOutput has exactly TWO callers in the whole image --
RegisterMaxOutput (assembly) and the SeekVoltageGraph sampler -- and
speedEffect@0x31C is a published GAUGE attribute.

The authentic myomer system (now fully live):
1. drive heat (#85, this morning);
2. VITAL death -- myomers are the only authored vital=1 subsystem
   (BTL4.RES res+0x48 scan): destroying them kills the mech via the #80
   vital-crit path (this is also the ram-death mechanism -- myomers are a
   0.35-weight collision-rattle target);
3. the assembly-time gait cap: RegisterMaxOutput @004b8ef0 raises
   mech+0x7A0 to AvailableOutput(top gear) = base x ~1.4284 -- now called
   (idempotent max, per tick; the 0x358 layout lock leaves no latch room)
   with real OwnerBaseSpeed/OwnerMaxSpeed bridges; the old per-frame
   reverseSpeedMax2 heal that would have clobbered it is garbage-guarded;
4. the ENG-page power curve at correct absolute scale (real base speed);
5. electrical sourcing (low gears run on a browned-out generator).

REMOVED (inventions): the mechmppr `speedDemand *= speedEffect` demand
multiplier + BTMyomersDriveOf + the Myomers ConnectToMover/MoverAttach
family.  Damaged-but-alive myomers heat faster and drop the power curve
but do NOT slow the mech (gitea #75's premise is falsified by the binary;
the real damage slowdown is the LEG-damage gimp gait).  Seek gears change
heat/sourcing/graph -- never speed.

Verified live: a mech at myomer dmg=0.234 (speedEffect attr 0.766)
beelines at full commanded speed with dmgGain=1.234 heat; 0 faults.

Joe DiPrimaandClaude Fable 5 31552c0444 #88 part 2: the central coolant pull-through -- HeatSink::DrawCoolant was a 
return-0 stub; the Reservoir BAR now drops when a damaged mech leaks

The user watched the coolant panel's level bar during the leak bench and it
never moved -- correctly: a leaking subsystem drained only its own loop,
because the slot-14 top-up (DrawCoolant) was stubbed.  Disassembled the real
base @0x4add00: the draw RECURSES UP the sink linkage, scaling by
coolantFlowScale@0x15C per hop, terminating at the Reservoir's supply
(@0x4af3b0 -- clamp to [0, coolantLevel], drain the tank, return granted --
already faithfully ported as Reservoir::DrawCoolant).  The binary's terminal
hop is the bank's slot-14 override @0x4ae8b0 resolving its reservoir
connection @0x1D8 (the port's 'helper' member -- not vestigial after all);
the port's existing Reservoir-ctor Attach + Reservoir override terminate the
same chain equivalently (the extra bank hop scales by ctor-default 1.0).

Implemented the base recursion (null-guarded -- the binary calls through the
resolved link unguarded; authored topology always links) + a BT_COOL_LOG
[resdraw] probe at the supply.

Verified live: a destroyed myomer's damage leak pulled the central tank
6.0 -> 5.58 over ~30s ([resdraw] granted lines) -- Reservoir/CoolantMass,
the cockpit coolant bar, now visibly drops as a damaged mech bleeds
coolant, and DeathReset refills it on respawn.

Joe DiPrimaandClaude Fable 5 a8a0042f28 #88: coolant leaks LIVE -- the #64 damageZone shadow was the single break 
in the leak chain

HeatSink::UpdateCoolant prices the damage-driven leak from the QUALIFIED
engine member (Subsystem::damageZone @0xE0): coolantDraw = zoneDamage *
heatLoad, with the coolantActive hysteresis (= the ReportLeak attribute
the 19 authored leak watchers ride).  But the MechSubsystem ctor only
ever filled its re-declared SHADOW member (gitea #64, gotcha #1), so the
engine member stayed NULL forever, zoneDamage pinned 0, and a coolant
leak was STRUCTURALLY IMPOSSIBLE no matter how much damage landed --
Oracle's night-7 report exactly.  The #80 crit fix and the #83 collision
rattle write real subsystem-zone damage, but into an object the leak
reader could never see.

Fix: alias the ENGINE base member to the same zone in both MechSubsystem
ctors.  Every shadow reader keeps working (same object); the engine base
Subsystem::TakeDamage latent null-AV (#64 consequence 2) is disarmed;
the full #64 de-shadow sweep remains the long-term cleanup.

Verified live (solo, BT_COOL_LOG/BT_CRIT_LOG): collision rattle drove a
damaged Myomers to [cool] draw = dmg*heatLoad with the level draining;
sustained weapon fire rolled real crits ([critroll]) and produced 588
leak-pricing lines.  Authored routing extracted from BTL4.RES: collision
rattle targets HeatSinkBank 0.3 / Gyro 0.35 / Torso 0.25 / Myomers 0.35
(Condenser+Reservoir authored 0 for collisions); weapon crits select via
the zone's crit-entry list.  Known-remaining fidelity item (documented):
HeatSink::DrawCoolant (slot 14, central top-up) is still a return-0 TODO.

Joe DiPrimaandClaude Fable 5 1570983fde #85: myomer drive heat LIVE -- the five Mech motion operands were return-0 
shims, so the reconstructed integrator @004b8d18 accumulated zero forever

The integrator, its gates and the heat plumbing were all reconstructed and
running -- but OwnerVelocityMag/OwnerDriveMag/OwnerVelocityY/OwnerMotionGain/
OwnerMass were cross-family compile shims returning 0.0f, so the myomers
priced ratio^2 * damageGain * 0 every tick: ice cold at any seek (Oracle's
night-7 panel-confirmed report).

Operands re-grounded against the raw disasm + decomp and mapped to NAMED
members via a complete-Mech-TU bridge (BTMechMyomerMotionSample, mech4.cpp),
per the databinding rule:
  +0x1C4 vec  -> localVelocity.linearMotion
  +0x82C vec  -> localAcceleration.linearMotion (the authentic 15-ring
                 smoothed AccelerationLastFrame the port already maintains)
  +0x20C      -> moverMass (the collision divert's cell; the old "motion
                 gain" label was a misread)
  *(+0x250)   -> environment gravity (FUN_00421e2c: vy -= **(+0x250)/tick),
                 via GetEnvironment()->gravityConstant
So the heat physics reads: 0.005 * 1/2 m v^2 (kinetic work, per-tick/no-dt
in the binary -- kept verbatim, frame-rate note documented) + 0.2 * m g
|vy| dt (climb power) + 0.2 * m |v||a| dt (acceleration power), all scaled
by ratio^2 and (1 + zone damage).  Restored the binary's fabs(v.y) (the
draft had signed vy -- descending would have COOLED).

Authored tuning extracted from BTL4.RES (18 mech records, one shared
tuning): VelocityEfficiency=0.995, AccelerationEfficiency=0.8, gears
0.3/0.5/0.7/0.9999 rec idx 2; myomer thermal profile 77/1000/2000,
conductance 1.9e5, thermalMass 2.5e5.

Live-verified (solo arena, BT_MYO_LOG + BT_HEAT_LOG): standstill generates
~0; hard circling drove Myomers T 77 -> 1225 (past the 1000 degradation
line) and the coolant loop conducted it back to ~520 equilibrium on
slowing; damageGain live at 1.048 from grind rattle.

Known-inert remainder (filed in open-questions): the climb term reads g=0
because Mover::localEnvironment is never populated in the port
(EnvironmentZone res type 23 unwired); the mover feed (speedEffect ->
locomotion) stays WAVE 6.

Joe DiPrimaandClaude Fable 5 37dd7f9663 collision-pricing audit: restore the binary's crash economy -- two fixes 
A. KNOCKDOWN PACING: the 0.4s gBlockCooldown contact-hysteresis is gone.
It suppressed the crash knockdown for as long as contact was held, letting
the kinematic drive re-slam the obstacle at full commanded speed EVERY
FRAME -- continuous full-price crash self-damage, a healthy 65-tonner dead
in ~2-3s of grinding (the night-7 SAURON ram death, 110 priced frames at
|v|~34.7).  The binary needs no guard (crash threshold @0x4ab178 read from
the exe = 0.0, dispatch per blocked frame is authentic): the bmp clip
zeroes the drive, and a pressed mech re-triggers the knockdown at v>6.3
long BEFORE its grind can price anything -- the type-0 divert's 0.5-pt
free floor needs v>~18.5 at 65t.  Wall grinding is free taps + paced
staggers; only genuine fast arrivals pay.

B. RAW RAM DISPATCH: the *0.001 "ram economy normalization" (2026-07-12)
predated the #83 type-0 divert and became a double-normalization -- the
victim's divert scale (~4e-5) compounded with it, so NO physically
possible ram could clear the 0.5-pt free floor: rams were a no-op against
the victim while the rammer's own un-scaled crash path rattled for real.
The binary dispatches raw [T1 @part_012:15324]; the divert IS the
normalizer.  Also un-starves cultural-icon crunches (trucks now crush on
contact per their authored armor, not after ~19 bumps).

Bench (scratchpad/night7/mp_rampricing.sh):
- wall leg: 150s full-throttle wall push = 125 paced knockdown binds
  (~1.2s cadence, iv2 40-43), 4767 crash frames ALL under the free floor,
  0 rattle, 0 deaths (pre-fix: dead in seconds).
- ram leg: BT_GOTO=enemy + BT_GOTO_STOP=2 rams the peer; raw amount
  arrives byte-identical on the victim (66239.1 tx == rx), victim prices
  2.55 pts internal rattle (first ram damage to a victim in the port's
  history), pressed follow-ups free, 0 deaths both nodes, 108 knockdowns
  -> exactly 108 type-5 records on the observer (no skating regression).

KB swept: combat-damage.md (the 1.3e6 moverMass mis-attribution corrected
to the measured 60-90k tonnage scale), locomotion.md, rendering.md.

Joe DiPrimaandClaude Fable 5 054c3f2eee #94: replicant un-wreck now rides the DEATH-STATE EXIT edge -- the zone 
falling-edge latch was blind to zone-less (collision) deaths

The peer wreck lifecycle listened to two different signals: wreck ON came
from the replicated death explosion (unconditional), wreck OFF from a
damage-zone falling edge (wasWrecked latch, armed only when a zone crossed
>= 1.0 on the observer).  The #83 collision damage prices as internal
rattle and never moves a zone, so a fresh mech killed by ramming could
NEVER un-wreck on peers -- the live respawned mech drove around wearing
the hulk (night-7 field report: SAURON's Loki, screenshotted by both
observers at the exact minute the log analysis places the ram death).

MechDeathHandler::Tick now tracks prevMode and fires the rebuild + warp
when the replicated MovementMode leaves the death modes {2,9} -- only
Mech::Reset ever does that, and the state rides every record header, so
the trigger is cause-agnostic.  The zone falling edge just refreshes the
cache.  Side effect fixed for free: the peer respawn warp vortex now
plays for zone-less deaths too (same gate).

Bench (scratchpad/night7/mp_zoneless.sh + the new
BT_SELF_DAMAGE_TYPE=collision harness option, which dispatches type-0
through the real TakeDamage divert): 14/14 zone-less deaths un-wrecked
(mode 9->1) with zero zone rises on the observer; explosive regression
leg 12/12 with zone destruction active.

Joe DiPrimaandClaude Fable 5 14ff3519ac #83: the COLLISION DIVERT -- type-0 damage prices as internal rattle, never armor 
The crash self-damage reconstruction (9c83a46) exposed its missing second
half: the binary's TakeDamage hub DIVERTS damageType 0 (@0x4a0368) into
FUN_0049ffcc -- an export-gap distributor recovered by raw disasm -- so
collision damage NEVER reaches the zone/armor loop.  Without the divert the
mover's raw kinetic-energy figure (60-ton mech: ~1000+ per wall tap, 90k+ on
a hard slam) fell into the WEAPON loop: 'tapped a wall and died instantly'.

The distributor, byte-anchored: gate on the owning player's advancedDamage
copy (+0x268 -- the manual's 'splash/collision damage' technician setting);
scale = (2000/moverMass) / (100 km/h in u/s)^2 / (1 - elasticity^2)
(tbyte 1/3.6 @0x4a0148; mass @+0x20c; elasticity @+0x244); scaled < 0.5 is

@0x10C) via ApplyDamageAndMeasure (@0x4ac07c).  Bridges: family derivations
(heat/gyro/torso.cpp), BTPlayerAdvancedDamageOn (btplayer.cpp).

Verified: bhk1 wall test -- 94k slam = 4.2 rattle pts in 8 sub-hits, taps
free (0.049 < 0.5), armor untouched.  A/B: arena wall-grind now 0 deaths,
27 rattle events, the limper STAYS GIMPED and peers' replicants re-enter the

gimp entries).  [crashdmg]/[colldmg] probes document the pricing.

type-5 KNOCKDOWN broadcast floors all peers' replicants into knockdown/trn
churn: gliding + leg-lifts = skating.  Turning and crushable cars were
A/B-exonerated (grass circling: 198 replicant gimp entries, 17 crunches,
zero broadcasts).

What the binary has that the port lacked -- recovered from the EXPORT GAP by
raw disasm (scratchpad/night6/gap_4a9770.txt, @4aa89f-4aaab4) -- is the crash
branch's tail: fallDirection = worldToLocal(damageForce) (FUN_0040879c, M^T v,
un-normalized), fallScalar = -(fallDirection . localVelocity.linearMotion),
and a self-dispatched TakeDamageMessage{0x64, zone=-1, the engine-computed
collision Damage verbatim}.  A wall crash COSTS ARMOR, so the grind degrades
the mech instead of looping forever.  That dispatch was the long-standing
'DEFERRED' note in the response policy; now reconstructed.

Falsified en route (comments + KB corrected, do not revive): the stagger's
FUN_004a4c54(1)/(0x20) 'action-request flags' feed NO drive suppressor --
image-wide sweep + full gap disasm show word[this+0x18] is read only by the
net record emitter; the bmp clip applies NO root motion (adv=0 measured); the
'gimp cap 5.8' figure was the BACK-cycle stride printed under a misleading
label (now ggCapL/R; @0x52c has no binary consumer).

Verified (mp_gimpAB rigs): arena1 wall-grind now 4 bounded strikes, limper
dies of its crashes and respawns cleanly twice (START->RESET, no strand);
grass circling unchanged-clean (198 replicant gimp states, 0 knocks).
Rig: pid capture race fixed (a missed winpid left a stale node holding the
-net port -> null runs), per-config sweep added.

Joe DiPrimaandClaude Fable 5 19fe1e5fa2 KB: the wall-grind knockdown storm IS the surviving #82 skating -- A/B-isolated 
Four-config matrix (mp_gimpAB.sh, [animind] replicant-state verdict):
grass straight/circle = clean replicant limp (198 gimp entries; 17 car
crunches during it -- crushable path broadcasts nothing, cars exonerated);
arena1 straight = one wall strike, replicant recovers into the limp;
arena1 circle = wall GRIND -- the bmp stagger clip's ~6.5 u/s root motion
re-strikes the wall (6.5^2 > iv2 threshold 40), each rebind re-broadcasts
the type-5 knockdown (26x in the user's run), and every peer's replicant
lives in knockdown/recovery churn: gliding + trn leg-lifts = "skating".
Turning while gimped is innocent; single strikes are benign.

Authentic fix filed in open-questions: reconstruct the consumer of the
stagger's action-request flags (FUN_004a4c54 bits 1/0x20 -- the drive
suppressor while the bmp clip plays); the rebind guard at mech4.cpp:6861
is already marked bring-up-pending exactly that.

Joe DiPrimaandClaude Fable 5 4e89baeff3 bench parity: local nodes now launch exactly like a player's shortcut 
Local benches had drifted from the shipped launchers and every divergence
cost a debugging session:

  * no BT_START_INSIDE -> benches opened in the EXTERNAL CHASE camera while
    every player starts in the COCKPIT.  The first first-person look at a
    bench window was misread as a broken HUD.
  * novice bench eggs  -> every SHIPPED egg is expert; novice gates off the
    entire heat model, crits and jams, so bench combat was not field combat.
    (Verified: the aligned node now boots experience=3 simLive=1
    heatModelOn=1, where it used to boot 0/0/0.)
  * 1-LP affinity pins -> starved the gauge executive and produced a false
    "the comms panel never counts deaths" reading.  Two LPs per node keeps
    the documented single-box jitter fix without the starvation.

scratchpad/night6/bench_common.sh now owns the contract (bt_player_env,
bt_launch, bt_expert_egg, bt_novice_egg) copied verbatim from play_solo.bat,
with bt_assert_player_env warning if the shipped bat ever drifts.  All three
4-node benches source it.  The limp bench keeps a novice egg -- expert crits
the aimed leg and the mech turns-but-never-moves -- and now says so loudly.

Also: BT_SHOT_EVERY=<n> headless backbuffer capture (btl4vid.cpp), the tool
this was diagnosed with.  It must sit above the warp phase-0 early-out since
that fn is the per-frame alpha-pass hook.  OS screen-capture is off-limits:
a foreground-lock failure photographed the user's browser instead of the game.

KB: build-and-run.md gains the bench-parity rule + the capture diag;
cockpit-view.md gains the measured aspect/FOV finding (the surround's 2.05:1
view collapses vertical FOV to 31.5 deg vs the pod's 46.8, so fixed canopy
geometry covers 68.6% of the lower half -- NOT a regression: the shipped 643
binary reports identical geometry).

Joe DiPrimaandClaude Fable 5 82f1ea1183 bench: symbolic leg-zone targeting, gimp-follow/goto-release, legal egg colors 
- BT_SELF_DAMAGE_ZONE=leg resolves the mech's actual leg zone via the
  streamed LegDamageZone flags (new Mech__DamageZone::IsLegZone) -- numeric
  zone ids are per-mech-type and a wrong one aims at a vital (killed the
  limp bench's mech instead of gimping it: 2 ticks, death cycle, respawn
  healed, harness spent -- 3 minutes of healthy circling).
- BT_GOTO=gimp: beeline mode that prefers the nearest LIMPING peer (gimp
  half-states 3/4 ride the one-cell in every update record); stands and
  waits while nobody limps.  BT_GOTO_RELEASE=1 hands the mech back to the
  keyboard once the beeline arrives.
- MP.EGG/MP4.EGG/MP4L.EGG: color=Red and color=Blue are PATCH values, not
  colors (RES vehicletable colors: Black/Brown/Crimson/Green/Grey/Tan/
  White) -- the two pilots carrying them rendered as untextured pastel
  mechs.  Boreas Red->Crimson, Caicias Blue->Grey.  MP4L.EGG = the 4-pilot
  bench egg on the open grass map.

4-node limp verification (user-eyeballed, all instances): the gimped mech
step-drags with the authentic limp on every observer -- no skating (#82
holds in the 4-node overlap case).

Joe DiPrimaandClaude Fable 5 494f32efb4 #45 ROOT CAUSE + FIX: the gauge executive starves in MP -- panels froze at healthy fps 
Instruments repaint via the background task pump, which authentically runs
ONLY in the frame's leftover time with a floor of ONE pump per frame; the
gauge renderer is 1 of ~7 round-robin tasks and each turn advances ONE gauge
of ~140 active, with the rate mask advancing once per full sweep.  On a busy
MP mission the foreground eats the whole frame budget, the floor becomes the
norm, and the whole instrument stack rotates once in MINUTES at perfect fps:
comms-panel K/D stuck at 0, recharge tickers frozen, while the tallies and
their replication underneath were exactly right.  Measured: 4-node bench at
70-90 fps gave the PilotList ~2 Execute turns in six minutes.

Fix, both env-tunable, authentic behavior restorable:
  BT_BG_MIN      (APPMGR.cpp, default 32, 0=authentic)  minimum background
                 pumps per frame regardless of slack;
  BT_GAUGE_BATCH (GAUGREND.cpp, default 32, 1=authentic) gauges advanced per
                 gauge-renderer turn (a visit is only a rate-mask check
                 unless the gauge is due).
Verified 4-node self-damage bench: sweeps 0.006/s -> 18-20/s, PilotList ~10
Exec/s, ALL FOUR panels tracked every death live (0->11) within ~1s, bg cost
2-4 ms/frame, respawn ledger clean (40 cycles, 0 swallow / 0 mismatch).

Also: BT_PERF now reports gaugeTurns/sweeps/active alongside bgTasks;
BT_AF_PERIOD now throttles the missile autofire group too (unthrottled spam
trips the documented FailureHeat all-weapons brick, which froze run 1 of the
cross-fire bench).

Joe DiPrimaandClaude Fable 5 bfa1b04990 #81 follow-ups: peer warp must not stomp the POV vortex; panel draw probe; mech3 ghost symbols 
Two field observations from watching the 4-node stress, both run down:

1. "A respawn happened without the blue vortex" -- REAL.  The translocation
   effect is ONE global slot shared by the POV lifecycle and the world-anchored
   peer sphere (a port extension).  A peer's un-wreck arriving while the local
   pilot's own collapse/wait/expand was in flight overwrote gWarpPhase/gWarpPOV
   and killed the POV vortex.  Invisible before the respawn fix only because
   overlapping respawns barely existed; now they are routine.  Fix: the POV
   lifecycle owns the slot -- BTStartWarpEffect self-skips while it is active
   ([tloc] peer warp SKIPPED).  2-node bench: 20/20 POV collapse+expand pairs,
   9 peer spheres played, 11 correctly skipped; solo: 8/8 pairs unchanged.

2. "Comms panel counted no deaths" -- panel machinery CORRECT; the 4-node
   zeros were the bench's own CPU crush (4 core-pinned instances starved the
   PilotList to <0.6 Hz, so rows redrew minutes-stale).  Added the arbiter:
   [score] panel DRAW slot/pilot/kills/deaths edge log (BT_SCORE_LOG) -- the
   2-node rerun drew 0->9 / 0->11 live on both nodes, local AND replicated
   (SBMIRROR rows confirm owner->replicant tally flow on all 4 stress nodes).

Also: the mech3 offline-authoring stubs declared every <Subsystem>::DefaultData
as Entity__SharedData while the real statics are Simulation__SharedData (this
engine derives Entity FROM Simulation) -- ~20 ghost symbols /FORCE silently
resolved to garbage.  DefaultData half fixed (SubsystemDefaultData now returns
the true common base Simulation::SharedData); the CreateStreamedSubsystem stub
signatures remain wrong (nested SubsystemResource* + ResourceFile*), are
cold (no callers), and are tracked in open-questions + gotchas §6 stub-typedef
corollary.

Joe DiPrimaandClaude Fable 5 830a976192 #81: 4-node stress PASS -- 56 overlapping death cycles, zero strands; DEATHS tally exact 
Four simultaneous networked nodes, all dying every ~35s on staggered timers so
respawn handshakes overlap (the field condition that stranded 6 of 8 cycles):
56 cycles, every completed one START->RESET, 0 swallowed / 0 mismatch /
0 discarded / 0 ghost / 0 crash.  Scoreboard: every node's PLAYER_DEAD rows
show deaths=N tally=N in lockstep (13/13/15/15) -- exactly one increment per
death, so removing the duplicate VehicleDead dispatch did not drop the DEATHS
column and the latch release did not double it.  The kill-credit path evaluated
all 56 deaths and correctly declined each self-kill (NOCREDIT self=1); KILLS
uses the separate ScoreMessage path the fix never touched.

Joe DiPrimaandClaude Fable 5 a357dc4265 #81 GHOST MECH FIXED: release the death latch + stop the duplicate VehicleDead 
Two defects that were masking each other, both now fixed and benched.

1) THE LATCH NEVER RELEASED ON FAILURE.  The binary's FUN_004c012c tail is
   Post(...) ; *(this+0x290)=0 ; *(this+0x258)=0   (part_013.c:10519-10523).
   We had the Post and the suppressConsole and were missing the middle
   instruction, so deathPending cleared only on SUCCESS paths.  One failed
   respawn latched the pilot for the whole mission: every later death hit the
   dedup and was SWALLOWED, so the cycle could never restart -- a transient
   hiccup became a PERMANENT ghost (dead, un-Reset, still driveable, a burning
   wreck on every peer that sinks after ~18s and can never be drawn again).
   Binary evidence: +0x290 is written in exactly THREE places in all of
   BTL4OPT.EXE (0x0b75fb, 0x0bffe3, 0x0c0a05) and all three store a ZEROED
   register; there is no write of 1 -- or any non-zero, in any instruction form
   -- anywhere.  The dedup gate itself IS authentic (@004c05c4 does
   mov edx,[ebx+0x290]; test edx,edx; jne ret), so it is kept.

2) VehicleDeadMessage WAS DISPATCHED TWICE PER DEATH.  BTPostKillScore
   (btplayer.cpp:2263) sent a second one "to credit a death", but that message
   is the RESPAWN-CYCLE TRIGGER, not a scoreboard increment, and the tally is
   already credited by the handler's ++deathTally (:538).  Both fire inside the
   same death transition (BTPostKillScore at mech4.cpp:2006, the hardened
   authentic notify at :2110), so they were always paired.  Removed; the kill
   credit above it is untouched (it correctly uses a ScoreMessage).

THEY HID EACH OTHER: the duplicate made the latch look necessary, and the latch
made the duplicate invisible.  Every "death ... SWALLOWED" warning in the field
logs was just the latch deduping our own duplicate -- 8 of 8 deaths, a 100% base
rate, which is exactly why it correlated with nothing when tested.  Fixing
either alone makes things visibly worse (the first bench of fix 1 alone produced
a DOUBLE cycle: deathCount double-incremented, cycle 1's re-post gone stale and
tripping the drop-zone MISMATCH).  That is why earlier passes at #57/#55 kept
adding clear-sites instead of finding the root; the binary broke the tie.

VERIFIED
  solo: 17 consecutive death/respawn cycles, every one START->RESET,
        0 swallowed / 0 mismatch / 0 crash.  Pre-fix this strands permanently
        after cycle 1.
  MP  : two nodes over a real network path with cross-machine drop-zone replies
        (each node's request is answered by the OTHER machine) -- A 11 cycles,
        B 12, 0 swallowed / 0 mismatch / 0 discarded / 0 crash.
  harness: BT_SELF_DAMAGE_REPEAT=1 re-arms the self-damage bench after respawn
        so multiple cycles can be driven (a one-death harness can never
        exercise this fix).  scratchpad/night6/mp_ghost.sh.

Joe DiPrimaandClaude Fable 5 d4ba91bd39 #81 THE ANSWER: deathPending is OUR invention -- the binary has no death latch 
Read BT's own respawn code and checked it against BTL4OPT.EXE itself.

FAITHFUL: BT's Player::VehicleDeadMessageHandler (FUN_0042db80, part_003.c:12029)
gates on message->deathCount == player->deathCount AND player+0x40 != 1
(simulationState != DropZoneAcquiredState) -- exactly WinTesla's two gates --
then runs the same closest-DropZone search skipping "win*" zones, dispatches
AssignDropZone and re-posts to itself on a timer.  So the retry loop and the
cross-machine hunt are authentic 1995 behaviour, not a WinTesla artifact.

NOT FAITHFUL: BT's BTPlayer::VehicleDeadMessageHandler (FUN_004c012c,
part_013.c:10504) ENDS with *(param_1 + 0x290) = 0 -- it CLEARS the field our
reconstruction calls deathPending, at the end of every death.  Verified in the
raw binary: +0x290 is written in exactly three places in the whole executable
(0x0b75fb, 0x0bffe3, 0x0c0a05) and ALL THREE store a zeroed register (xor
ecx,ecx / xor eax,eax / xor edx,edx immediately before).  There is NO write of 1
or of any non-zero value to +0x290 anywhere in BTL4OPT.EXE.  Two are ctor/reset
sweeps; the middle one is the death handler, sitting right after the call to
Post and add esp,0x14, matching the decompiled tail exactly.

So 1995 has NO death-pending gate.  We invented it (btplayer.cpp:505) and then
needed six clear sites to patch the strandings it caused (:382 :469 :1431 :1442
:1461 :1532).  #57 and #55 are artifacts of that invention.  It is also what
makes a ghost PERMANENT: in BT a failed respawn is harmless (the 2s re-post
keeps hunting, the next death starts a clean cycle); in ours the first failure
latches the pilot and every later death is SWALLOWED forever -- exactly the
field signature of 8 cycles, 6 stranded, none recovering.

Fix proposed in the doc (match the binary: clear instead of latch, drop the
dedup gate) but NOT applied -- six sites depend on the latch and the dedup is
load-bearing, so it wants a deliberate two-node bench, not a 1am edit.

Joe DiPrimaandClaude Fable 5 bf0555ccf1 #81: every MP respawn is a cross-machine round trip -- one degraded peer ghosts everyone 
Two-node bench with the fixed host:local labels shows each player's drop-zone
request is answered by the OTHER machine's DropZone: A asks, B grants; B asks, A
grants.  FindGroup("DropZones") iterates replicants of remotely-mastered zones
too and takes the geometrically closest, so a respawn is
  my request -> an arbitrary peer's DropZone -> that peer's reply -> back to me.
With 5 players that is 5 round trips through arbitrary peers, and ONE degraded
peer can strand everybody else's respawn.  That finally explains the otherwise
unexplained field datum that one machine stopped processing the death-transition
stream 57% into a match and never recovered (0 explosions/wreck swaps/burials
while four other machines logged 4/4/4) -- a node in that state cannot answer
anyone's respawn.  It also explains why solo is 100% reliable (in-process) and
why a healthy 2-node bench passes.

Also fixes the instrumentation before it costs a night: every [dz] line printed
"entity 1" because a player's LOCAL entity id is 1 on every machine -- with five
players the log would have said a respawn stalled but not WHOSE.  All [dz] lines
now print host:local (including the usedBy= owner of each busy slot).

Doc: two candidate fixes recorded (prefer a locally-mastered DropZone / make the
reply path tolerant of a deathCount that is ahead of ours), neither to be guessed
at -- the [ghost] DISCARDED line's mismatch direction decides it in one line.

Joe DiPrimaandClaude Fable 5 0dbdad17f3 #81 ghost: light the SILENT DISCARD -- the only path a respawn can vanish on 
Walked the respawn handshake end to end and measured the assumptions.  Two
eliminations and one find:

ELIMINATED: the engine hunt re-posts to itself every 2s forever while the mech
is dead (PLAYER.cpp:325-327; its only state-based exit never fires, see below),
and the DropZone re-grants the SAME slot to a repeat request from the same
requester+deathCount even while busy (DROPZONE.cpp:182-194).  So neither a
transient "no slot" nor a single lost reply can strand a respawn -- the request
keeps being re-sent and re-granted.  A permanent strand needs a permanent cause.

THE FIND: BTPlayer::DropZoneReplyMessageHandler ends
  if (!playerVehicle) ... else if (deathCount == message->deathCount) ... else { return; }
and that last branch was a BARE RETURN WITH NO LOG.  The drop zone grants a
spot, replies, the numbers disagree, the reply is dropped, deathPending stays
latched, the mech is never Reset -> permanent ghost, zero evidence.  That is
why 6 of 8 field cycles stranded silently.  Now always-on, printing the
DIRECTION of the mismatch: msgDeath < ours = genuinely stale (dropping is
right); msgDeath > ours = our counter is behind and we just threw away a LIVE
respawn -> points straight at #45 (the death tally does not replicate).
Deliberately NOT auto-recovered: guessing would be a stand-in, and the wrong
guess resets a mech that is still alive.

LANDMINE DOCUMENTED IN CODE: Set_Alarm_Level is an empty stub (btstubs.cpp:87),
so the death path's Set_Alarm_Level(this+0x2c,1) and the reply's (+0x2c,2) are
no-ops.  Their values decode against Player's enum as DropZoneAcquiredState(1)
and VehicleTranslocatedState(2), which makes "these should obviously be
SetSimulationState() calls" both attractive and CATASTROPHIC: the engine hunt is
gated on GetSimulationState() != DropZoneAcquiredState, so setting 1 on death
would stop AssignDropZone ever being dispatched and ghost EVERY pilot.  Measured
our simulationState at 0x24 (not 0x2c) and the write leaves it 0; in the binary
+0x2c is the Simulation-base alarm (the field the mech side calls graphicAlarm,
@0x4ac126 "owner alarm+0x2C -> level 9"), which our layout models only on Mech.

Verified solo: a healthy death+respawn logs the grant and the RESET and emits
ZERO discard/gate-off lines (no false positives).

Joe DiPrimaandClaude Fable 5 372cbfa344 docs: GHOST_MECH_ANALYSIS -- the field analysis, durable across sessions 
The ghost and the "wreckage moving and shooting" are the SAME failure at two
ages: a stranded respawn (drop-zone reply never arrives) leaves the mech never
Reset and never repainted, and the render-side wreck swap is ONE-WAY -- so the
pilot drives a burning hulk that sinks (pure ~18s timer, btl4vid.cpp:1277) and
then cannot be drawn at all.

Records: the 8-cycle ledger (only 2 of 8 reached RESET; stranded correlates with
ghosting 8/8 and 10/10); the host did not ghost because he never died; the
SWALLOWED warning is BENIGN (100% base rate) and two earlier readings of mine
that were wrong (spurious resets = aggregation artifact, per-match player IDs);
the WinTesla-vs-1995 provenance caveat on DROPZONE.cpp; what the new
instrumentation already killed (slots=8, so dropzone=one is not the bottleneck);
and the four-separate-bugs breakdown of the "desync cluster" including the
machine that stopped processing the death-transition stream mid-match.

Raw per-machine logs + the verbatim agent findings stay in scratchpad/night6/
(uncommitted -- machine names + Steam identities).

Joe DiPrimaandClaude Fable 5 ba6756c40a drop-zone / respawn instrumentation: make the GHOST MECH visible in field logs 
The ghost (a player who dies, never respawns, stays dead-but-driveable and is a
wreck on every peer) traces to a respawn stalling on drop-zone acquisition:
DropZone::AssignDropZoneMessageHandler grants a slot only if IsAvailable(), and
when none is free it reposts to ITSELF every 0.1s at MaxEventPriority and never
replies -- so deathPending is never cleared.  This whole subsystem was DARK: not
one drop-zone line in a full night of field logs.

ALWAYS-ON (no env gate -- rare, catastrophic, field-only, same rationale as the
#57/#59 guards; volume bounded and rate-limited):
  [dz] POOL   -- slots + downTime + proximity radius, once per mission
  [dz] GRANTED-- one per respawn, with the WAIT time; tags (GHOST RECOVERED)
                 when a long-stalled request finally lands (what testers see as
                 "it fixed itself")
  [dz] STALL / GHOST LIKELY -- escalating, per-waiter rate-limited, and it names
                 WHY each slot is busy (age + last user), which discriminates
                 cooldown saturation from proximity blocking -- different fixes
  [dzreq]     -- the REQUESTER half: re-try count for this death, and msgDeath vs
                 our own deathCount.  The engine gates the hunt on those being
                 equal AND the DropZone resend net is keyed on the same value, so
                 a mismatch breaks both silently (cf #45, tally replication).
BT_DROPZONE_LOG=1 adds the verbose per-request slot dump for bench work.

First run already overturned a theory: slots=8, so an 8-slot pool cannot be
cooldown-starved by 5 players (max 5 on cooldown at once) -- the shared
dropzone=one in eggmodel.py is NOT the bottleneck.  Suspicion moves to the
handshake (lost reply / deathCount mismatch).

Verified with NO env vars set, exactly as a tester runs it: 4 probe lines for a
full death+respawn cycle, all in the normal day log.

Joe DiPrimaandClaude Fable 5 e1c15eb806 #82 peers see a limping mech SKATING: the mech erased its own gimp cell every frame 
The binary's one mech+0x40 IS Simulation::simulationState, which rides EVERY
update record header -- so in 1995 a peer's replicant learned the gimp level on
every packet and its gait limped with no gimp-specific replication anywhere.
The port's Mech::PerformAndWatch wrote SetMovementMode(1) every frame ("ground,
non-death, non-airborne"), which erased the level once it was mirrored in for
the warning voice (#78): the wire carried 1, bystanders walked while sliding at
limp speed, and the voice sequence restarted on every damage event (1->4 edge
per tick) instead of announcing once.

- mech4: that per-frame write now writes the AUTHORITATIVE level
  (gimped ? 3/4 : 1) via a new alarm-only bridge BTMechGimpAlarmLevel -- which
  deliberately never consults the cell it feeds, so a respawn-cleared alarm
  cannot re-latch stale gimp out of it.
- BTMechGimpLevel: falls back to the replicated cell, with ONE-CELL precedence
  (a fall/death/limbo state wins, so the normal drivers and their death latch
  run -- what the binary's single cell enforced structurally).
- Reverted the #78 record guard: on a replicant the master's records are
  authoritative, so pinning 3/4 against them would keep a peer limping through
  a respawn.  Fixed at the writer instead.
- [simstomp] trap now scoped to the watched mech with a module-relative return
  address (symcrash-able) -- that is what named the writer.
- Also learned + recorded: zone damage levels replicate only when the EXPLOSION
  TABLE's tier is crossed (peer measured at 0.428 vs master 0.857), so peer-side
  damage state must never be inferred from them.

Verified two-node (scratchpad/night6/mp_skate.sh): the observer's replicant gets
sim=4 and its gait runs 23 -> 25 (wgr entry -> ggl limp cycle).  Field clue that
cracked it: "after respawning a peer DID see the limp" (epilectrik/SAURON).

Joe DiPrimaandClaude Fable 5 98907f45af hotfix: null-damageZone guard on the crit path (field crash, build 641, Conn Man's Owens) 
First field session with real crits (#80) found a weapon subsystem with a
NULL damageZone: Mech__DamageZone::CriticalHit -> ApplyDamageAndMeasure ->
MechWeapon::TakeDamage +0xf (the engine base derefs the zone unguarded --
every 1995 subsystem shipped with one).  Stack symbolized from the field log;
the path was unreachable before tonight because ApplyDamageAndMeasure was a
stub until #80.

Guards at both choke points; a one-shot [crit] log NAMES the zoneless
subsystem when hit so the root cause (build that subsystem's zone) can be
fixed from the next field log.  Owens crit bench: no crash, guard inert on
zoned subsystems.

Joe DiPrimaandClaude Fable 5 1ac425860e particles.png recovered (#79, found by cyd) -- particle texture ships at last 
content/VIDEO/particles.png (128x128 RGBA): the texture L4PARTICLES has tried
to load since the engine was written.  Boot-verified: [particles] device
objects created (max=8192, texture=loaded).  Every particle effect now draws
textured -- the authored look; the arcade pods displayed untextured quads
because the file never shipped.  Comments updated to match.

Joe DiPrima cfa52a28d8 Merge remote-tracking branch 'origin/glass-cockpit-refit' 2026-07-29 19:56:31 -05:00
Joe DiPrimaandClaude Fable 5 5b19cd6c3f demo/bench harness polish: BT_SELF_DAMAGE_DELAY + two harness bug fixes + the OBS limp demo bat 
- BT_SELF_DAMAGE_DELAY=<s>: hold the harness off for n seconds (capture demos:
  healthy walking first).  Fixed its underflow bug (the countdown crossed below
  zero, which is also the "read the env" sentinel -- the delay re-armed forever).
- The one-death latch was fed by EVERY mech's update: a mission that generated
  any destroyed mech entity tripped it at frame one and the harness silently
  never fired (random per mission roll).  Now viewpoint-mech only.
- run\limpdemo.cmd: the OBS capture demo -- 30 s healthy auto-walk, then the
  leg crosses half on the final damage tick: klaxon-klaxon-"reverse disabled"
  + the limp, then unlimited limp footage (waypoint 8000,8000).

Joe DiPrimaandClaude Fable 5 18766a167b locomotion.md: correct the gimp-audio verdict -- the reverse-disabled voice is real and wired

Joe DiPrimaandClaude Fable 5 1671b7d4b2 the REVERSE DISABLED voice (#78): SimulationState 3/4 IS the trigger -- mirror the gimp level into the engine cell 
User + old-timers were right; the earlier "no voice exists" verdict was wrong.
The authored mech audio has state watchers on Entity.SimulationState==3/4
(the binary's one-cell mech+0x40) that start sequence notes 29,16,40 -- two
klaxon hits then Warnings01 zone 8 (key 40-41) = the "reverse disabled"
voice line the testers remember.  The port's cell split (graphicAlarm vs
engine simulationState, gotcha #23) meant the trigger value never arrived.

- mechdmg: mirror gimp 3/4 into SetSimulationState at the leg-half crossing
  (guarded: never stomps disabled/fall/dead states).  Voice verified playing
  end-to-end on the bench: SetupPatch bank2 patch113 note=40 ->
  Warnings01_z7.wav.
- mech.cpp: BT_GIMP_SAFE_BASE_READ on all seven Simulation::ReadUpdateRecord
  sites -- gimp is monotonic per life; a record captured pre-gimp must not
  stomp the cell (the loopback otherwise perpetuates the stale value and
  restarts the warning on every damage event).
- diagnostics (all env-gated): [statefire]/[startreq]/[animind]/[gimp-sim]/
  [simstomp]/[indstomp] + StateIndicator::DebugAudioWatcherCount + raised
  spatial-log caps.  These traced the whole chain and PROVED no SetState
  path stomps the cell.

OPEN (follow-up): a RAW writer (bypasses SetState entirely; invisible to the
indicator-level trap) resets the cell between damage events -- under the
bench's 1 Hz metronome harness it restarted the sequence before the 1.8 s
voice note; sporadic real-play damage is unaffected (one edge -> full
sequence).  Needs a cdb write-watchpoint session; candidates: a recon raw
+0x2c-equivalent write or a struct copy spanning it.

Also decoded en route: the AnimationState triggers on the limp states play
EngineShiftRev01 (the downshift foley) -- working, and NOT the voice.

Joe DiPrimaandClaude Fable 5 95cf49d1b6 gimped turn-in-place (#78 field find): arm the trn step in the gimp leg driver 
Field test: a gimped mech pivoted as a rotating statue.  The binary's
turn dispatcher (FUN_004a9b5c, master perf) runs OUTSIDE the driver
selection so it arms trn for gimped mechs too -- 71f4's case 4 exists to
advance it.  The port relocated that dispatcher into the NORMAL leg
driver's Standing case, which stops running when the gimp driver takes
over.  Mirror the arming (same gates + lockstep body arm) into
AdvanceLegAnimationGimp's Standing case.  No gimp-turn clip exists in the
RES -- a limping mech step-turns with the normal trn clip, authentic.

Field-verified: stepping pivots both directions while gimped, heading
sweeping, clean re-entry into the wgr/ggl limp on throttle-up.  [T2]

Joe DiPrimaandClaude Fable 5 36f68718c2 the visible limp (#78): there was never a jump-jet clip set -- the 'Airborne' drivers ARE the gimp gait machines 
The port had FUN_004a5bf8/71f4 fully reconstructed as AdvanceBody/Leg-
AnimationAirborne, gated on (MovementMode()==3||4) && jumpCapable@0x580 and
believed dead ("the test mech never jumps").  The binary says otherwise:
mech+0x40 in that gate is the graphicAlarm LEVEL (3=left-leg gimp, 4=right)
and +0x580 is hasGimpClips, set by the conditional loader block that probes
'wgl' and fills clip slots 22-27 (wgl/wgr/ggr/ggl/gsl/gsr) plus the four
measurements at 0x53c-0x548 (wg entry strides = speed caps, gg cycle strides).
Renamed the five jump* members + both drivers accordingly.

New: GimpBodyClipFinished @004a6344 / GimpLegClipFinished @004a7970 -- the
gimp transition machines, branched from the normal finished-callbacks.  Phase-
correct limp entry (left-gimp enters 0x16/wgl only from a RIGHT step, right-
gimp 0x17/wgr from a LEFT step), gg cycles at gimp cadence, gs exits, and the
demand clamp to the gimped side's speed cap (leg cb writes it back into the
mapper -- the binary's authentic slowdown; the T3 x0.5 stand-in in mechmppr is
retired, BT_GIMP_SPEED now defaults 1.0).  The binary's gimp machines have no
reverse entry -- the "reverse disabled" behavior is now binary-proven.

Reviving the dead drivers replayed two port-glue bugs (gotcha #24): the raw
*(controlSource) mapper read (null -> crash at first engagement) and the
missing alarm->member state re-sync (machine pinned in one run state).  Both
fixed; bench harness gained BT_SELF_DAMAGE_TICKS=<n> to hold a zone past
LegHalfStructure without destroying it.

Bench-verified (madcat, novice, zone 16): crossing -> alarm 4 -> wgr entry
from a left step -> 8k+ frames stable in the ggl limp cycle at cadence 14.77
(vs 18.5 walk / 22+ run) with raw demand still 50.  [T2]

Joe DiPrimaandClaude Fable 5 520f6eecd3 myomer damage reaches the wheels, legs gimp at half structure, reverse refuses -- and an ODR trap unmasked (#75/#78) 
The speed-demand site (MechControlsMapper::InterpretControls) now applies the
drive scale the mover's feed roster applied in 1995: speedDemand multiplies by
the myomers' live speedEffect (gear ratio, thermal curve, 1 - zone damage, via
the BTMyomersDriveOf bridge) and, while GIMPED, by 0.5 [T3: VGL Lynx's
"roughly 50%", BT_GIMP_SPEED overrides]. The gimp states were already being
raised -- mechdmg sets graphicAlarm 3 (left) / 4 (right) when a LegDamageZone-
flagged zone crosses half structure -- but nothing downstream ever saw them.
While gimped, reverse input is refused ("reverse disabled"), matching the
old-timers' account; the pod's audio cue rides the alarm's watchers.

Bench, one trajectory, arithmetically exact: a deterministic right-leg ramp
(the new BT_SELF_DAMAGE_ZONE harness) crosses 0.5 and the demand goes
44.837 -> 6.726 = 44.837 x 0.5 (gimp) x 0.3 (a crit-chewed myomers from the
same ramp -- the #80 crits composing with #75's scale, unprompted).

The reason "nothing downstream ever saw them" is the real find of the night,
now gotcha #23: AlarmIndicator is typedef'd to DIFFERENT TYPES per header
family -- mech.hpp says ReconAlarm (4 bytes), heat.hpp says GaugeAlarm (0x54)
-- so Mech::graphicAlarm and EVERY member after it sit at different offsets
depending on a TU's include order. mechdmg wrote level 4 and read it back;
mechmppr read 0 from the same object, same expression. No compiler error can
catch it: each TU only ever sees one definition. Until the split is audited,
cross-TU reads of the gimp level go through BTMechGimpLevel (compiled in
mechdmg's TU) -- and the same split-brain explains why the port carries the
binary's ONE movementMode cell as two live members (engine simulationState vs
graphicAlarm level) that never meet.

Also landed en route: the Myomers un-powered self-repair observed healing in
the field logs at exactly 0.011 x the authored Explosive scale per tick --
the 2026-07-29 reversal confirmed live; and Mech message 0x15 "RealMaxSpeed"
raw-decoded (@0x49f604: sets mech+0x7a0 from the message unless the +0x7a4
latch holds -- a console-tunable top speed).

Open on #78, documented in locomotion.md: the Gimp animation clips (authored
keys in the binary's model-record parser; mech2's state enum vs mech3's
reverse-fix disagree about slots 0x12-0x17 -- reconcile before wiring) and
the audio-cue binding.

Joe DiPrimaandClaude Fable 5 8a99972f22 aimed fire strikes the part under the crosshair: the per-segment pick (#73) 
The port's target pick was a whole-mech bounding-box slab test, and every hit
-- aimed or not -- dispatched zone -1 into the victim's cylinder lottery. The
recovered 1995 model (the division-card scene intersection) struck a SEGMENT
and credited that segment's own damage zone. This is the port's equivalent.

At render-tree build, each segment's draw object and its PrimaryDamageZone --
authored per segment in the skeleton stream, read by JMOVER.cpp:290 -- are
recorded in MechRenderTree::segPick. The pick (BTL4VideoRenderer::
MechSegmentPick) ray-tests the per-segment bounding spheres on the live posed
skeleton, using the draw-cached mLocalToWorld (at most one frame stale, fine
for aiming).

Selection is SPECIFICITY-FIRST: among the spheres the ray pierces, the
smallest radius wins, normalized-distance tie-break. Both obvious rules were
measured failing the same way before this one: the torso mesh's sphere
(r~4.1 on the MadCat, vs shoulders at r~1.0) envelops nearly the whole mech,
so its front face is nearest for any aim AND any near-body ray normalizes to
~0 against it. Limb spheres nest inside the envelope; smallest-pierced picks
the most specific part on the aim line, and the torso wins only when no limb
is threaded -- the per-part semantic the pod's mesh test produced.

mech4.cpp tries the segment pick per candidate; the box PickRayHit survives
only as the fallback (no tree yet, wrecked, spectator), still carrying zone
-1 into the lottery, and a structure occlusion clears the zone. The winner's
zone rides MECH_TARGET_SUBIDX + targetReticle.targetDamageZone into
SendDamageMessage, so aimed hits now dispatch a real zone; the victim's
handler applies it directly (bursts 2+ still re-lottery, authentic per the
recovered @0x4a0230 loop).

Bench, the same L/C/R sweep that exposed the bug: aiming left now lands
36/41 hits on zone 2 = jointlshoulder -- the left arm -- with a 0.30 thread
score, where the same aim was a 6-way lottery spray before. The MadCat's
authored segment->zone map is rich (shoulders 2/9, guns 6/17, hip 1, six leg
zones, torso 0). Known approximations, flagged for field verification:
sphere bounds rather than triangles, and a torso-envelope graze credits the
torso where the pod's exact mesh test would have missed into air.

The field protocol is the one the testers already ran on night 6: stationary
mechs, short range, fire only at one arm -- the paper doll should now damage
THAT arm.

Joe DiPrimaandClaude Fable 5 e110b10ac8 the #73 pick dig, part 2: there was never a software pick -- the division card cast the ray 
The hunt for the un-decompiled pick writer ends with the reason no scan could
find it: it does not exist. In 1995 the pick was a DPL SCENE INTERSECTION run
by the video board. The evidence converges from five directions:

  - The WinTesla renderer still carries the result slots: dplHitInstance /
    dplHitDCS / dplHitGeoGroup / dplHitGeometry + vehicleReticle, NULL-inited
    in the ctor and never fed by the port.
  - The stubbed 1995-era renderable constructors each took dpl_isect_mode_obj
    ("type of intersections to do on this object") plus an intersection MASK
    -- every scene object was configured for ray queries.
  - Auric, quoted in the KB long before this dig: "the pod's division card
    cast from the view."
  - VGL Lynx's night-6 LOD warning ("the hit test may run against a different
    LOD") reads as firsthand knowledge: the ray tested the DRAWN geometry.
  - Exhaustive byte- and pseudocode-level scans: nothing in the binary writes
    rayIntersection/targetEntity/targetDamageZone. Game code only reads them,
    constructs them (the Mech ctor @0x4a1674 -- identified this dig, along
    with vtable +0x18/+0x1c = Mech::Read/WriteUpdateRecord, nine replication
    groups, reticle not among them), gates them (FUN_004afd10, the look-state
    machine: per-view crosshair positions, the pi rear case, the per-weapon
    rear-fire mask walk), and ships them to the board for drawing
    (FUN_00460a7c packages rayIntersection + elementMask into dpl).

What this means for #73: aimed fire in 1995 had PER-PART precision -- scene
ray, struck triangle on the active LOD, the DCS is the segment, the segment's
dzone is the credited zone. The cylinder lottery was only ever the UNAIMED
path. The port's whole-mech box pick funnels aimed fire through the unaimed
lottery, which is exactly what three testers documented on night 6: aim at
the arm, get the spray.

Fix design recorded in the KB: a per-SEGMENT ray test on the shooter side
(inverse(segmentWorld) * ray vs each segment BGF's local extent box, nearest
wins, its dzone dispatched as the aimed zone), falling back to box+lottery
when no segment resolves.

Joe DiPrimaandClaude Fable 5 bcbc7cff12 the #73 pick dig, part 1: mech+0x36c is an embedded engine Reticle -- the writer is still at large 
Chasing the un-decompiled targeting pick (the residual of #73). The hunt for
"who writes mech+0x37c/0x388/0x38c" kept coming back empty for a structural
reason now understood: those three fields are the tail of an embedded ENGINE
Reticle struct at mech+0x36c (RETICLE.h lays out position/state/pickPointingOn/
rayIntersection/targetEntity/targetDamageZone/elementMask, landing exactly on
0x37c/0x388/0x38c). Writers carry &mech->reticle and use small reticle-relative
offsets, invisible to any mech-relative displacement scan.

T0 corroboration, ENTITY3.h:131: "For BattleTech, damage zones are only valid
via reticle based weapons."

Ruled out as the writer: the engine Reticle itself (passive container -- ctor
and resource parse only); HudSimulation @0x4b7830 (holds &owner->reticle in esi
for its whole body but only READS the pick -- range caret, designator
transform -- and slews reticlePosition via the @0x4b7ed4 ease); the 0x482xxx
sites (mission-table target bookkeeping, address-of computations); the gyro
coefficient reads at 0x4b2c24/5c/6e (that class's own +0x370..0x38c table).

Still dark, with the candidates mapped: the un-exported 0x4a1674-0x4a2d48
stretch (reticle-touching at 0x4a16a5 in the Make-time init, 0x4a1f93, and a
state+pickPointing+base trio at 0x4a294a-61 near entry 0x4a2971), the two
unidentified Mech vtable overrides +0x18/@0x4a122c and +0x1c/@0x4a0c2c (both
big switch functions), and a few lone sites. One of these computes the
authentic pick; recovering it answers whether the pod tested the aim ray
against the mech's cylinder (as the damage table's geometry suggests) or a box
like the port's stand-in.

Recorded in combat-damage.md \xc2\xa7Targeting so the next session starts from the map
instead of the empty scans.

Joe DiPrimaandClaude Fable 5 a5fb96ae96 the crit system, complete: two gap functions recovered, the dead sink revived, and a wrong verdict reversed (#80) 
The whole critical-hit pipeline was dark, three layers deep, and one of those
layers had fooled us into a false conclusion about the 1995 binary itself.

LAYER 1 -- the trigger, recovered from the un-exported gap. The Mech MESSAGE
TABLE at 0x50bdf8 ({id, name, handler} rows) names the real
Mech::TakeDamageMessageHandler at 0x4a0230 -- message 0x12 "TakeDamage" --
plus seven sibling handlers (PlayerLink, RealMaxSpeed, BalanceCoolant,
Set/ClearBurningState, EjectPilot, DuckRequest). Inside it, the crit chance
at 0x4a0164: p = clamp(0.7 * damageLevel^2 + 0.01, 0..1), gated on the
player's simLive flag (+0x25c -- novice never crits), rolled PER BURST on the
current zone, skipping a zone already burning. Chance is ~1% on fresh armour,
~18% at half-stripped, ~58% at 90% -- crits arrive exactly as armour fails.

The handler's application loop replaces the engine base's single call, which
ignored burstCount entirely (multi-burst damage under-applied (burst-1)x).
Faithful shape: per burst, crit-roll -> CriticalHit @0049ccc4 (which routes
half the amount through the armour internally and picks ONE critical
subsystem by criticalWeight) else zone->TakeDamage -- then RE-RUN the
cylinder lottery from the impact point for the next burst, stopping early
once the mech is disabled. Multi-burst damage sprays across zones by design.

LAYER 2 -- the sink. MechSubsystem::TakeDamage was an empty btstubs stand-in;
the real body is at 0x4ac0bc (CLASSMAP had that address mislabeled
"HandleMessage"): zone damage, then on level >= 1.0 the Destroyed alarm, the
PrintState gate, the 1.0 pin, and -- for a vital subsystem -- the owner
mech's graphicAlarm to level 9, the same fall/death level the leg path
raises. That is the #28 vital-subsystem kill machinery, now real.

LAYER 3 -- the one that rewrites yesterday. The subsystem ctor DID copy
armour points + per-type scales into the private zone -- through the
ReconDamageZone PROXY, whose fields sit at struct offsets +4/+8, not the
binary's +0x140/+0x144. The floats landed on the engine object's header and
the real damageScale[] stayed zero. The 2026-07-28 experiment that "proved"
subsystem zones cannot be damaged -- and that the Myomers un-powered
self-repair was dead code in the original -- was measuring exactly this port
bug. Both verdicts reversed: the binary ctor (0x4ac7bb) initializes the zone
from the resource keys WeaponDamagePoints (required) + CriticalHitScoreBonus
(required) + Collision/Ballistic/Explosive/Laser/EnergyDamagePoints, none of
which the CSS parsed. Now parsed (with the binary's own error strings), and
the ctor writes the engine's NAMED members -- layout-parity holds, so they
land on +0x140/+0x144 faithfully. The Myomers repair branch is LIVE, in 1995
and here. KB corrected and swept (combat-damage, subsystems WAVE 6,
myomers.cpp, CLASSMAP).

Live-verified twice: [subarmor] prints real parsed scales for every subsystem
at spawn (HeatSink pts=10 scale=0.1x5, Condensers pts=5 scale=0.2x5, ...);
[critroll] landed full-chain crits in both runs (zone -> weighted pick ->
subsystem's own zone driven to 1.0 -> Destroyed); mech death/respawn and the
ammo gates un-regressed; zero crashes/asserts. Honest gaps: burst>1 spraying
is transcribed but not yet exercised live (self-damage fires burst=1), the
damageType==0 COLLISION divert (@0x49ffcc) is documented-not-reconstructed,
and the id-0x16 damage/kill report messages to the players (the authentic
stats plumbing, decoded to field level in the KB) are deferred to the #45
work.

Joe DiPrimaandClaude Fable 5 f7cf9850b1 crit panel: the roll has no caller and the sink is a stub -- filed as #80 
Night-6 observation (Conn Man, with screenshot): armor panel showing damage,
Critical damage display showing no crits. Investigated; it is a real port gap
in three layers, stacked on one authentic fact.

The authentic fact: the paper doll shows per-ZONE armor tint and the Critical
view is a per-SUBSYSTEM list. Different data by design -- the panel staying
dark while armor accumulates is correct right up until a subsystem takes
critical damage.

The gap: subsystem critical damage essentially cannot happen.

  1. Mech__DamageZone::CriticalHit @0049ccc4 -- the authored roll, half the
     hit to armour, half to one critical subsystem by criticalWeight -- has
     ZERO callers in the port. A raw byte-scan of the binary finds exactly
     one call site, @0x4a0461, and it sits in the un-exported decomp gap
     (nothing covers 0x4a03xx-0x4a05xx, the same dark region as the
     targeting-pick writer). The trigger conditions are unknown.
  2. MechSubsystem::TakeDamage is an empty bring-up stub (btstubs.cpp:179),
     so even a wired caller would measure a delta of zero through
     ApplyDamageAndMeasure.
  3. The only live crit sources are zone destruction (SendSubsystemDamage)
     and ammo cook-off (DistributeCriticalHit), which pin subsystem damage
     directly -- so the panel can light after a zone is destroyed outright,
     never from accumulating fire.

#28 (the vital-subsystem-crit death path) very likely shares this root and is
cross-linked. Recovery plan on #80: raw-disasm the 0x4a04xx container for the
trigger, dump MechSubsystem vtable 0050e210 slot +0x24 for the real TakeDamage
body, wire both.

Joe DiPrimaandClaude Fable 5 a5dd0eabc5 issue #73 investigated: zone selection is a weighted lottery -- per-limb aiming never existed 
Night-6 report: three players, controlled conditions, "fired only at the left
arm, damage credited all over the paper doll, no crits". Chased it to the
bottom and the bottom is the authored 1995 model, working as designed.

The zone a hit credits is chosen by dice, in binary-faithful code reading
binary-shipped tables (dmgtable.cpp, stream format byte-verified): impact
point -> height layer (floor(layerCount*y/heightRef)) -> pie slice
(atan2(z,x) around the vertical axis, optionally rotating with live torso
twist) -> DamageZonePercentTable::SelectZone() = RandomUnit() rolled against
cumulative percent thresholds (@0x49de14). Every slice carries an authored
DISTRIBUTION of zones. Aiming at a limb at best biases which slice you
strike; the zone inside it is a weighted roll. Pixel-precise limb damage
does not exist in Tesla 4.10.

Measured live to be sure the code read was real: solo dummy, walked to 8u,
aim pinned left/center/right across the silhouette, trigger held. 24-46
hits per aim point, each spread across 6+ zones (the percent tables), with
the distribution shifting by aim point (the slice selection responding).
Both halves of the model visibly working.

What remains genuinely open, and is now the whole of #73: the shooter's pick
point comes from Mech::PickRayHit, a whole-mech AABB slab test -- a port
stand-in, since the binary's 0x37c/0x388/0x38c writer sits in an un-exported
gap nobody has decompiled. Theta computed from a flat box FACE clusters
toward the slices facing the shooter, so flank slices (presumably arm-heavy)
may be under-reachable from frontal shots compared with the pod, which
plausibly intersected the mech's cylinder -- the damage table is literally
cylindrical. Deciding that needs a per-hit theta probe and a one-shot wheel
dump; if confirmed, the fix is a ray-vs-cylinder pick replacing the box slab.
Filed on #73 with the plan.

KB: combat-damage.md gets the lottery model as a load-bearing triage fact --
"damage landed somewhere I didn't aim" now has a documented base rate, and
crit expectations from aimed fire are probabilistic by design.

Joe DiPrimaandClaude Fable 5 dca2586aa8 the Owens crash: a device reset that never waited for the device (#35) 
Eight byte-identical field stacks from night 6, all one player, all in an
Owens: ParticleEngine::Destroy +0x11, access=0 target=0x0, from the plain
per-frame render path. Nothing in the stack touches weapons or the Owens.
Conn Man's Surface Pro 9 (Iris Xe, 128 MB shared) is simply the only GPU in
the fleet that ever actually LOSES the D3D9 device -- his two-trigger
missile+laser bursts are what provoke the timeout, not what crashes.

What crashed is our device-loss handling, which was wrong three ways at once,
in two inline copies (the scene Present and the wait-screen Present):

  1. On D3DERR_DEVICELOST it called Reset() IMMEDIATELY. Reset on a
     still-lost device ALWAYS fails, and V() only logs. There was no
     TestCooperativeLevel gate at all.
  2. It then ran ParticleEngine::Initialize against the lost device. The
     creates fail there and NULL their out-params -- proven, not assumed:
     the bench repro faults at target=0x0, not at a dangling address.
  3. The next lost frame called ParticleEngine::Destroy again, which
     Release()d those NULLs blind. Read of vtable at 0x0. Dead.

So: lost frame 1 tears down and leaves NULLs, lost frame 2 crashes. Two
frames, every time, deterministic -- which is exactly why all 8 field stacks
are byte-identical.

Reproduced before fixing. BT_DEVICELOST_TEST=<frame>,crashrepro runs the
field sequence on the bench; on the unfixed build it died at Destroy +0x11,
access=0 target=0x0, and symbolized to the same four frames as the field
logs. Same shape, same offsets-modulo-hook. That run also proved the
out-param-nulling assumption the whole diagnosis rested on.

The fix -- one shared DPLRenderer::BTResetLostDevice() replacing both inline
copies:

  - Destroy() is idempotent and null-safe, and nulls after release.
  - Reset() is gated on TestCooperativeLevel() != D3DERR_DEVICELOST; while
    the driver still says lost, skip the frame and retry.
  - The Reset HRESULT is checked; on failure, log and retry next frame
    instead of driving on.
  - On success, re-create via the new CreateDeviceObjects(), NOT
    Initialize(): Initialize memsets the installed-effects table, so every
    reset that DID succeed silently killed all particle effects for the rest
    of the mission. The quieter sibling bug, fixed by the same split.
  - Initialize checks its HRESULTs and defends MAXPARTICLES<=0; the draw
    paths guard the NULL buffer, and ExecuteParticles keeps draining
    particles while the engine is dormant so they cannot pile up.

Verified: the crashrepro shape now logs SURVIVED and play continues; three
forced full loss/reset cycles each log "[render] device reset OK"; a plain
run is assert-free.

Found while verifying, worth its own line: VIDEO\particles.png has NEVER
existed -- not in the tree, not in BTL4.RES, not anywhere in git history.
The texture load has failed on every machine since the engine was written,
and every billboard particle ever rendered was untextured quads via
SetTexture(0, NULL). RenderParticles deliberately does NOT gate on the
texture -- that would disable all particles everywhere; untextured IS the
shipped look. Filed separately; a real particle sheet is a content task.

The field verification that counts is Conn Man flying his exact crash
loadout on this build: instead of a dead process he should see at worst a
brief hitch and "[render] device reset OK" in his log. #35 stays open until
that happens.

glass generations (`-net 1501 -platform glass`, "relaunched generation"); one glass block = one
drop, and boundaries are synchronized across every machine to ±2 s (mission-clock expiry relaunches
all peers' menus in the same second). **Stub anatomy:** the steam lobby is CLICK-driven
(`steamAction`, btl4fe.cpp), so a menu closed without a click logs exactly **4 boot lines** and
exits 0 — a 4-line stub at end-of-night is a player going to bed, NOT a crash (all four machines
ended night-14 with identical 4-line stubs at 00:31:2x). 7–8-line stubs = a lobby cycle
(`[steamnet] up` + `[lobby] join` + map). `BTCrashFilter` is armed before the first log line and
writes a `[crash]` block + module-relative stack on ANY unhandled exception — a silent log end
means quit/kill/hang, never an unlogged AV. **`lastrun_<stem>.txt` caveats:** appends stop silently
if the file gets locked (the `is_open` guard skips) — a lastrun ending mid-night while the log
continues means the file was captured/locked during live troubleshooting, not that the chain died.
And the bat sign-off ("The game has exited. If it closed unexpectedly, send…") prints after ANY
chain end including a normal quit — it primes players to report quits as crashes; #157 ("did not
exit cleanly") was exactly this echo. The arcade-authentic round-end (mission process exits →

Every shipped launcher (`play_solo.bat`, `join*.bat`, `play_steam.bat`) sets the SAME three
things, and a local bench that omits them is not testing the game the field plays:
set BT_PLATFORM=glass set BT_START_INSIDE=1 set BT_DEV_GAUGES=1
plus a front-end flag (`BT_FE_SOLO` / `BT_FE_JOIN`), `cd content`, and NO `-res`.
**`BT_START_INSIDE=1` is the big one** — without it a bench opens in the EXTERNAL CHASE camera
while every player starts in the COCKPIT. Benches ran chase-only for weeks; the first
first-person look at one was misread as a broken HUD [T2].
**Experience:** every SHIPPED egg is `experience=expert`. A `novice` bench egg silences the whole
heat model, crits and jams (see [[experience-levels]]) — bench combat then is not field combat.
Only the aimed-leg gimp bench may use novice (expert crits the aimed leg and the mech
turns-but-never-moves); it must say so out loud.
**Affinity:** pin each node to TWO logical processors (`0x03/0x0C/0x30/0xC0`), not one. Disjoint
core sets keep single-box packet delivery even (the peer-shakiness fix, [[multiplayer]]); ONE LP
per node starves the gauge executive and fakes a "the comms panel never counts" reading [T2].
`scratchpad/night6/bench_common.sh` owns this contract (`bt_player_env` / `bt_launch` /
`bt_expert_egg` / `bt_novice_egg`, and `bt_assert_player_env` warns if the shipped bat drifts).
The 4-node benches (`mp4_panel.sh` respawn+scoreboard, `mp4_cross.sh` real cross-fire kills,
`mp4_limp.sh` gait replication) all source it. A `-net` node renders NOTHING until
`tools/btconsole.py` starts the mission — a solo launch is the quick visual check.
## Headless frame capture — `BT_SHOT_EVERY` (2026-07-30)
`BT_SHOT_EVERY=<n>` dumps the game's own backbuffer every n frames to
`<BT_SHOT_PREFIX|shot>_NNN.png` (btl4vid.cpp, top of `BTDrawTranslocationSpheres` — the per-frame
alpha-pass hook; it MUST stay above that function's phase-0 early-out). This is how rendering is
diagnosed without foregrounding a window, and it is the ONLY capture method to use: OS
screen-capture grabs whatever is actually on the user's screen (a foreground-lock failure once
photographed the user's browser instead of the game) and is off-limits.
Frames land mid-alpha-pass, so a process killed during a write leaves ONE truncated PNG — skip it.

## Build ritual — the stale-link flake (bit 4+ times; MANDATORY for bench work)
MSBuild often does NOT relink `btl4.exe` when only static-lib members changed — the bench then
runs a STALE exe and the session burns hours on phantom results. Ritual for every code-change build:
1. `rm -f build/Release/btl4.exe` FIRST (force the relink);
2. build; a REAL relink prints the 20 known-benign `CreateStreamedSubsystem` LNK2019s (`/FORCE`
baseline — see the top of this file); an up-to-date run prints none;
3. STRING-VERIFY before benching: `python -c "d=open(r'build/Release/btl4.exe','rb').read();
print(b'<A-NEW-LOG-MARKER>' in d)"` — pick a string your change added (NB: release strings
carry LOG TEXT, not function names — check the .map for symbols);
4. use ABSOLUTE paths in every bench command — `cd` leaks between compound commands (the cwd
trap) and has broken builds/appends/copies repeatedly.

## ⚠ The canopy looks "obscured" at wide viewports — it is the ASPECT, not the canopy [T2]
`BTFovYFromHorizontal` (L4VIDEO.cpp:127) pins the HORIZONTAL fov at the authentic 60° and derives
the vertical from the LIVE aspect — correct at the pod's 4:3 (60°×46.8°), but the cockpit-surround
layout hands it a very wide, short world view and the vertical field collapses:
| viewport | aspect | vertical FOV |
|---|---|---|
| pod 800×600 | 1.33 | **46.8°** |
| surround default 900×500 | 1.80 | 35.6° |
| surround on a 1080p screen 900×440 | 2.05 | **31.5°** |
The surround height-clamps the view to fit the work area (`btl4main.cpp` ~1404: 900×500 → 900×440
on 1080p), so the smaller the screen the worse it gets. The canopy is FIXED world geometry, so a
1.5× vertical squeeze makes it eat 1.5× more of the view: measured on bhk1 at 900×440 the frame
covers **39% of the viewport — 9.5% of the upper half but 68.6% of the LOWER half**, i.e. the dash
rides up over the horizon and hides the ground where enemy mechs stand (user-reported as "can't
see to shoot"). At a true 4:3 world view the same build/mech/map renders a correct big-window
cockpit. Left/right skew is 6% (symmetric — nothing is tilted).
**Not a regression:** the shipped 4.11.643 binary reports identical geometry (`view 900x440
canvas 1452x999`), and the gauge-executive change is measurably innocent (canopy coverage 57–59%
with it on vs 60–61% off — scene variation).
**Verification method:** `BT_COP_PLATES=1` (kit off) gives a 100%-solid viewport vs 39% with the
stencil cut live — that is how to prove the punch kit is running. Canopy coverage = per-pixel diff
of a normal frame against a `BT_HIDE_COCKPIT=1` frame; a raw grey-pixel count also catches sky.
**Open decision (nothing changed yet):** cap the aspect used for fovY (wide windows would show
MORE horizontally instead of cropping vertical — identical to the pod at 4:3), or make the
surround's view taller (clamp width, costing surround width), or bench first-person work in the
dock layout (`BT_DEV_GAUGES_DOCK=1 -res 640 480`).

## The #91 "black rectangle" (thor) — own-body inside meshes + the blakskn rule [T2]
Three testers (Oracle + RajelAran night 7; Ronin 2026-08-03: "moves diagonally 10→4 with the
footsteps, at rest sits ON the lower frame bar, right side, half-in") reported a black
rectangle in the Thor cockpit. Decoded 2026-08-04:
- The rectangle is the **thor's own `thx_msl` missile-pod mount plate** — authored, authentic
own-body geometry (see the roster above; "Summoner" = the `thr1` FE label, same THX canopy,
so the cross-reference isolated nothing). It rides the walk-animated shoulder while the eye
rides the gyro springs → the diagonal footstep-rhythm sway. Pixel-tracked across walk
captures: ~29px wide, x/y oscillating together along the 10↔4 axis, bottom center-right,
alternating with the gait [T2, scratchpad/night11/thorrect.sh].
- **What WAS wrong:** the pilot-facing surfaces of these own-body meshes are authored with the
same `<pfx>skin:blakskn_dz_*` interior-structure material as the canopy frame (texture-less,
black diffuse, `softer` ramp lo 0.25 → hi 0.99), but the unlit frame-constant treatment was
keyed on the `_cop` FILENAME — so the identical material rendered (0.13,0.12,0.15) on the
canopy and PURE (0,0,0) on the pod/legs (`[matlog]`-verified: owx_cop blakskn vcol=FF211F26
vs owx_lule blakskn vcol=FF000000). Fixed in bgfload.cpp: the constant now keys on
`meshIsCop || material contains "skin:blakskn_dz_"`. `mechfx:blakskn_mtl` (tshd shadow
quads) deliberately does NOT match. Verified: zero pure-black pixels in the lower view band

## Targeting (mech offsets, [[decomp-reference]] §3)
**STRUCTURAL DISCOVERY (2026-07-29, the #73 pick dig): the target block is an embedded engine
`Reticle` at `mech+0x36c`** [T0 layout-verified]. `engine/MUNGA/RETICLE.h` lays out exactly:
`reticlePosition@0x36c` (Vector2D), `reticleState@0x374`, `pickPointingOn@0x378`,
**`rayIntersection@0x37c`**, **`targetEntity@0x388`**, **`targetDamageZone@0x38c`**,
`reticleElementMask@0x390`. This is why every "who writes 0x388" scan came back empty — writers
carry `&mech->reticle` (an `lea [mech+0x36c]`) and use small reticle-relative offsets.
`ENTITY3.h:131` states the model in T0 words: *"For BattleTech, damage zones are only valid via
reticle based weapons."* The engine `Reticle` is a **passive container** (ctor + resource parse
only — no pick math); `HudSimulation @0x4b7830` opens with `lea esi,[owner+0x36c]` and READS the
pick (range caret from `rayIntersection`, the designator transform) and slews `reticlePosition`
via `@0x4b7ed4`, but does not write the pick either. **The pick WRITER is BT code, still
unlocated** [T4 candidates]: the un-exported stretch `0x4a1674-0x4a2d48` (touches the reticle at
`0x4a16a5` — the Mech::Make-called init — and `0x4a1f93`, `0x4a294a/54/61` state+pickPointing+base
together near entry `0x4a2971`, which is called from `0x494483`), the two unidentified Mech vtable
overrides `+0x18=0x4a122c` / `+0x1c=0x4a0c2c` (both big switch functions), and lone sites
`0x4877a4` (byte read via the mission entity table `0x5015c8`), `0x4b0097`, `0x45fb14-24`.
**RESOLVED (same dig, deeper): there IS no software pick writer — the 1995 pick was a DPL SCENE
INTERSECTION** [T0 + T1 converging]. Evidence: (a) the WinTesla renderer still carries the result
members `dplHitInstance/dplHitDCS/dplHitGeoGroup/dplHitGeometry` + `vehicleReticle` (L4VIDEO.cpp
ctor, all NULL-init); (b) the stubbed 1995-era renderable constructors each took
**`dpl_isect_mode_obj` ("type of intersections to do on this object") + an intersection MASK** —
per-renderable intersection configuration against the scene; (c) Auric's account ("the pod's
division card cast from the view"); (d) VGL Lynx's LOD warning reads as firsthand knowledge — the
ray tested the DRAWN geometry, i.e. the active LOD's meshes; (e) exhaustive scans: nothing in the
binary or the pseudocode ever writes `rayIntersection/targetEntity/targetDamageZone` — game code
only reads, initializes (the Mech ctor @0x4a1674 constructs the embedded Reticle), gates
(`FUN_004afd10`, the look-state machine, toggles `pickPointingOn` per view with the π rear case),
and SUBMITS the reticle to the board for drawing (`FUN_00460a7c` packages +0x37c/+0x390 into dpl).
⇒ **Aimed fire in 1995 had PER-PART precision**: scene ray → struck triangle on the current LOD →
the DCS = the struck SEGMENT → its `dzone` (the SKL segment→zone map, `GetSegmentIndex@49db20`) =
`targetDamageZone`. The cylinder lottery (STEP 6) was only ever the UNAIMED path. The port's
whole-mech box pick + "STEP-6 zone under the boresight" funnels AIMED fire through the unaimed
lottery — which is exactly the night-6 report (#73): aim at the arm, get the spray.
**COMPLETED 2026-08-03 (#124, the zone-walk matrix): the pick is TRIANGLE-ACCURATE** [T2 matrix].
The sphere approximation measurably mis-picked (aim dead-on dtorso -> picked rgun/ruleg) —
`MechSegmentPick` runs a sphere PRE-FILTER then Moller-Trumbore nearest-hit over the threaded
segments' posed meshes (CPU triangle cache from each object's own BGF buffers, `BTGetPickMesh`).
**⚠ CORRECTED 2026-08-04 (field pushback from era players — they were RIGHT): the 08-03 zone rule
("the struck segment's SKL dzone, ALWAYS" -> every aimed torso hit = CENTER TORSO) was WRONG.**
The authentic rule: **the pick's zone is the struck PATCH's authored `dz_*` tag** — the art
zone-tags the hull PER PANEL (`MAD_TOR.BGF` carries `dz_utorso`×36 / `dz_ltorso`×18 /
`dz_rtorso`×18 / `dz_dtorso`×16 + all four rear panels + `dz_searchlight` across its patches
[T1 bytes]); the dpl hit result kept GEOGROUP granularity (`dplHitGeoGroup` in the renderer's
result block [T0]); and the binary's segment->zone map `@49db20` has NO runtime caller (sole
caller = `CreateStreamedDamageZone`, load-time — raw call-scan [T1]), so no segment-level
collapse mechanism even exists. Aimed fire in the pod stripped the exact hull panel under the
reticle. The segment-level model looked airtight because LIMBS agree at both granularities (one
zone per limb mesh) — the collapse only bit the hull, and Oracle's night-10 audit ("only LCT gets
hits") was the BUG's fingerprint, not the pod's design. Port: `MechSegmentPick` attributes the
struck triangle to its draw op (index-range) and takes the op's `.DZM`-bound zone (the #87
armour-darkening bindings — the same authored patch->zone mapping that already paints those
panels), segment dzone as the untagged-patch fallback; `ZoneAimPoint` aims hull zones at their
patch CENTROIDS so the zone walker can exercise per-panel. Bench: [[test-harness]] §zone-walk
(madcat variant, scratchpad/night11/zonewalk_madcat.sh).
**MISS-MEANS-MISS (#131, 2026-08-05) [T2 both-direction bench]:** the pick answers ONLY for
drawn geometry -- the any-object SPHERE fallback and the caller's whole-mech AABB fallback are
gone (sphere only for a mesh the reader cannot parse -- none exist, counters clean; AABB only as
the pre-tree replicant grace, `BTMechSegmentPick` returns 1/0/-1). They were port stand-ins the
1995 card never had, and their signature regime was a LEVEL boresight over a SHORT mech: the
blackhawk's mesh tops out below eye-ray height, so rays cleared every triangle while threading
the fat cull spheres -- lock ring lit with the reticle above its head (night-12 field report,
operator-witnessed on the sweep bench). Instruments: `BT_LOCK_SWEEP` (torso-pan lock envelope,
operator-watchable), `BT_LOCK_ENVELOPE` (synthetic unit sweep), `[picksrc]`/`[pickbox]` source
telemetry + objs/invFail/noTri localization. Locking is now strictly TIGHTER than 716-774; if
era testers report the pods were more forgiving, Draco's "slight lock linger" memory is the
sourced follow-up (tracked on #131).
**TWIST-SIGN VERIFIED (2026-08-04) [T2 live]:** the frame adapter's inferred angular flip
(`SelectSlice: theta -= TorsoHeading()`, vs the binary's `+=` before the z-reflection) is
CORRECT — bench: target torso pinned 0/+140°/−140° (`BT_FORCE_TWIST`, sim-level
`analogTwistAxis` hold in torso.cpp — the input-level pin is DEAD, live input rides the
CONTROLS.MAP device push and Basic mode auto-centers), LRM salvos (missiles = the authentic
cylinder consumers; the binary DROPPED zone-−1 beam damage). Slice picks track the
physically-facing flank in both twist directions (positive twist = `horizontalLimitLeft` =
CCW), deterministic; the wrong sign is cleanly excluded (would pick slice 7 where slice 1 is
observed). Diag: `[slice]` log (live twist, thetaIn/thetaAdj, wedge index) + zone NAMES on
`[dmgresolve]` (both under `BT_DMGTABLE_LOG`); bench `scratchpad/night11/twistsign.sh`.
**IMPLEMENTED (2026-07-29/30) [T2 bench]: the aimed PER-PART pick.**
`BTL4VideoRenderer::MechSegmentPick` (btl4vid.cpp): at tree build, each segment's draw object +
`GetPrimaryDamageZone()` (SEGMENT.h — carried per segment in the skeleton STREAM, read by
JMOVER.cpp:290) are recorded in `MechRenderTree::segPick`; the pick ray-tests the per-segment
bounding spheres (`mCullCenter/mCullRadius`, world via the draw-cached `mLocalToWorld` — ≤1 frame
stale). **Selection is SPECIFICITY-FIRST: among pierced spheres the SMALLEST radius wins**
(normalized `d²/r²` tie-break). Both simpler rules were measured failing identically: the torso
mesh's sphere (r≈4.1 on the MadCat vs shoulders r≈1.0) envelops the mech, so nearest-entry always
faces you AND normalized distance rewards the giant sphere (a 0.45u-off-axis ray scores 0.012 vs
it). Limbs nest inside the envelope; smallest-pierced picks the most specific part on the aim line
— the per-part semantic the 1995 mesh intersection produced. `mech4.cpp` tries the segment pick
per candidate (box `PickRayHit` + zone −1 → the unaimed lottery survives only as fallback:
no tree / wrecked / structure occlusion), and the winner's zone rides `MECH_TARGET_SUBIDX` +
`targetReticle.targetDamageZone` into `SendDamageMessage` — aimed hits now dispatch a REAL zone.
Bench (L/C/R sweep, dummy at 8u): aim-left = **36/41 hits on zone 2 = `jointlshoulder`** with

## "Mechs die with lightly damaged armor" — AUDITED, no port bug: it's AMMO COOK-OFF (2026-08-02) [T1 chain, T2 measured]
Field complaint (night 9): mechs die while their panels read nearly pristine, so "the scaling
must be off". A byte-level audit of the ENTIRE damage chain found **every link faithful**:
zone stream reads (arcade base ctor `@0041df5c` == engine DAMAGE.cpp, incl. the JointedMover
skip-5 branch); the BT ctor normalization loop (`@0049ce50` constants 1.0/1e-4/0.5 — and in
SHIPPED CONTENT the raw cells are EXACTLY `1/armorPts` uniform across all 5 types, so the
normalize is a no-op); `TakeDamage @0041e4e0` formula+clamps; the override `@0049c690`
(redirect gate, vital/leg thresholds 1.0/0.5/0.0 `@0049c99c..a4`); `CriticalHit @0049ccc4`
(fraction 0.5 `@0049ce48`, cap 1.0 `@0049ce4c`, the per-subsystem `applied<damagePercentage`
cap); the cook-off chain (`stamp @004bc3fc` per-SALVO before the missile divide, `CookOff
@004bd300` = ammoCount×amount, `DistributeCriticalHit @004ac274` = ÷(zones plugging the bin)
then one DESIGNATED-zone TakeDamageMessage each).
**The measured kill route** (death-kinetics bench, 7 deaths): 6 of 7 were **bay-fire
detonations** — e.g. `AmmoBinLRM15 10 rounds × 50 = 500 (burst 1)` into the bin's ONE authored
carrier zone (madcat bins are single-zone: LRM15_1=roster[26]→dz_ltorso, LRM15_2=[28]→dz_rtorso,
AFC100=[21]→{larm,lgun}), which is VITAL (madcat authors **15 of 22 zones vital** — all torsos,
legs, feet) → one application 0→1.0 → instant death, every other panel bright. The ÷1 is the
CONTENT's authoring, not a port shortcut — the arithmetic is the binary's own. The one mech that
died conventionally (300 applications) ended VISIBLY charred: 0.97/0.93/0.92/0.85/0.79 across 13
zones — mid-fight darkening DOES accumulate when mechs live long enough.
**Field logs confirm dominance**: Rajel's night-9 log alone has 12 bay-fire events (LRM10
455-490 pts); ConnMan 10; the "salvo barely dented my armor" reporter was dying to their OWN
cook-offs. **The real lever is HEAT** (bay fire arms at the bin heat-watcher's FAILURE level;
the [[subsystems]] heat/#96 too-hot economy arms it constantly) plus player training: EJECT
**hold** purges the burning bay (`DumpAmmo` → "bay fire EXTINGUISHED"); pod players were

The binary Missile hosts a **MissileThruster** subsystem: the round leaves the rack at the

ACCELERATES while BurnTime remains. Authored values (BTL4.RES type-15 missile model records

LRMs 10× slower than authored -- which was the whole of the field "missiles are slow" report,
and the "explosion before the missiles arrive" perception (the salvo-lead detonates while the
slow spread rounds straggle). Fixed: `BTMissileThrustOf` (mech4.cpp) lazily caches the RES
thruster table (ModelList ids aliased to their type-15 member); both launch paths (master fire
+ the replicant salvo mirror) pass burn/accel into the pool, whose advance integrates
`speed += accel·dt` while burning. Verified live: Streak impacts at 277 u/s (was 100).

## ⚠ A subsystem's PRIVATE zone cannot be damaged via `TakeDamage` (2026-07-28) [T0]
Each `MechSubsystem` owns a private `DamageZone` at `+0xE0`, built by the **2-arg trivial ctor**
`new DamageZone(this, 0)`. That ctor (`engine/MUNGA/DAMAGE.cpp:187-190`) zeroes **all five**
`damageScale[]` entries, `Reset()` never touches them, and the only other writer in the tree is
`Mech__DamageZone` — the mech's *streamed* zones (`mechdmg.cpp:246-253`), a different class. Since
`DamageZone::TakeDamage` is `damageLevel += damageAmount * damageScale[damageType]`, **any**
`TakeDamage` against a subsystem's own zone is arithmetically a no-op, whatever the amount or type.
Verified by experiment: a zone seeded to 0.6 and fed −0.011f for ~1500 ticks never moved.
The crit path works because it **bypasses this entirely** and writes `damageLevel` directly
(`DistributeCriticalHit` pins `*(this[0x38]+0x158) = 1.0f`; `ForceCriticalFailure` sets the state).
Practical consequence: if you are reconstructing something that "damages a subsystem", route it the
way the crit path does — a `TakeDamage` call there will silently do nothing. This is also why
Myomers' Performance `@004b8bb9` (an un-powered self-repair) is dead code in the 1995 binary itself:
see [[subsystems]] WAVE 6.
## ⚠ CORRECTED (2026-07-29, #80): subsystem private zones ARE damageable — the port was writing
## their scales through the WRONG LAYOUT
The 2026-07-28 verdict here ("a subsystem's private zone cannot be damaged via `TakeDamage` — in
the original too") was **wrong about the original**, and the experiment that "confirmed" it was
measuring a PORT bug. The truth [T1, raw disasm @0x4ac7bb + live-verified]:
- The binary's `MechSubsystem` resource ctor **initializes the private zone's armour**:
`defaultArmorPoints@0x140` ← resource `WeaponDamagePoints` (+0x44, REQUIRED key) and
`damageScale[5]@0x144` ← the five per-damage-TYPE keys
`Collision/Ballistic/Explosive/Laser/EnergyDamagePoints` (+0x30), normalized
`1/(scale·armorPoints)` exactly like the mech zones (without their extra ×0.5).
- The PORT had this copy — but wrote it through the **`ReconDamageZone` proxy**, whose
`structureReference/armour[]` sit at struct offsets **+4/+8**, not the binary's +0x140/+0x144.
The floats landed on the engine object's header and the real scales stayed at the engine ctor's
zeros — hence the frozen-damage experiment. Classic databinding trap, now on the engine side.
FIXED: the ctor writes the engine's NAMED members (layout-parity holds — `Mech__DamageZone`
locks its derived fields from 0x160 up).
- The port's CSS also never parsed the seven keys (now parsed; two are required with the binary's
own error strings).
Consequences: `MechSubsystem::TakeDamage @0x4ac0bc` (now real, was a stub) accumulates authored
per-type damage on subsystems; crits land and destroy subsystems; and **the Myomers un-powered
self-repair `@004b8bb9` was LIVE in 1995 and is live in the port now** — the earlier "dead code in
the original too" note in [[subsystems]] WAVE 6 is superseded. `DistributeCriticalHit`'s direct
`damageLevel = 1.0f` pin remains the ammo-explosion path, not the general mechanism.

Issue #73 ("fired only at the left arm, damage credited elsewhere, no crits") is **largely the
authored 1995 model, not a bug**. The chain (`dmgtable.cpp`, binary-faithful, byte-verified stream
format): impact point → `WorldToLocal` → **height layer** (`floor(layerCount·y/heightRef)`) →
**pie slice** (`atan2(local.z, local.x)`, optionally rotated by live torso twist —
`rotateWithTorso` per layer) → `DamageZonePercentTable::SelectZone()` = **`RandomUnit()` against
cumulative percent thresholds** (`@0x49de14`). Each slice sprays damage across an authored
*distribution* of zones — aiming at a limb at best biases WHICH SLICE you strike; the zone within
it is dice. Measured live (L/C/R aim sweep at 8u, `BT_DMG_LOG`): 24-46 hits per aim point spread
across 6+ zones each, with the distribution *shifting* by aim — the model working as designed.
Consequences for triage: reports of "damage landed somewhere I didn't aim" need this base rate
before being called bugs; crit expectations from aimed fire are likewise probabilistic.
**Residual genuine question [T3]:** the shooter's pick point comes from `Mech::PickRayHit` = a
**whole-mech AABB slab test** (a PORT stand-in — the binary's 0x37c/0x388/0x38c writer is in the
un-exported gap, never decompiled). Theta computed from a flat box FACE clusters toward the
facing slices, so flank slices may be under-reachable from frontal shots vs. the pod (which
plausibly intersected the mech's *cylinder* — the damage table is literally cylindrical).
Deciding whether that distortion is material needs a per-hit theta probe + a wheel dump (slices ×
percent tables, MadCat) — see #73 on the tracker.
## ✅ CRITS RECONSTRUCTED (2026-07-29, #80) — the section below records the GAP as found; all three
## layers are now fixed and live-verified
The recovery: the un-exported gap held `Mech::TakeDamageMessageHandler @0x4a0230` (found via the
Mech **message table @0x50bdf8** — rows `{id, name, handler}`: 0x12 TakeDamage, 0x14 PlayerLink,
0x15 RealMaxSpeed, 0x16 BalanceCoolant, 0x17/0x18 Set/ClearBurningState (⚠ label/body mismatch:
the 0x17 handler @0x49f674 randomizes position + graphicAlarm(2) + re-enables sim — not burning;
possibly a shifted name row, cf. the factory ClassID mislabels — open-questions), 0x19 EjectPilot @0x49f854,
0x1a DuckRequest @0x49fa00) and the **crit-chance roll `@0x4a0164`**:
`p = clamp(0.7·damageLevel² + 0.01, 0..1)`, gated on the player's `simLive` flag (+0x25c — novice
never crits), rolled per BURST on the current zone (skip if the zone is already burning). The
handler's application loop (binary @0x4a0423-0x4a04d8, now in `mech.cpp`): per burst — crit roll →
`CriticalHit @0049ccc4` (replaces the zone application; routes half through armour internally,
tally += the subsystem's `CriticalHitScoreBonus`) else `zone->TakeDamage`; then **re-run the
cylinder lottery from the impact point for the next burst** (multi-burst damage sprays), stopping
early once the mech is disabled. The engine base's single-application (which ignored `burstCount`
entirely — multi-burst under-applied (burst-1)×) is superseded. `MechSubsystem::TakeDamage
@0x4ac0bc` is real (zone damage → destroyed alarms → **vital-subsystem kill**: owner
`graphicAlarm` level 9, the #28 machinery — CLASSMAP's "HandleMessage@4ac0bc" was a mislabel).
Live-verified: `[subarmor]` shows parsed scales at spawn; `[critroll] zone=3 -> Myomers subLvl=1`
— a full chain crit destroying a subsystem. The `damageType==0` COLLISION divert (@0x4a0368 →
`0x49ffcc`) and the id-0x16 report tail are BOTH reconstructed — see the next section. Diags:
`BT_CRIT_LOG` (`[subarmor]` + `[critroll]`), `BT_DMG_LOG`.
## ✅ THE AUTHENTIC SCORE/DEATH REPORT TAIL (2026-08-05, #45/#134) [T1 raw disasm, T2 both benches]
The rest of `Mech::TakeDamageMessageHandler` (@0x4a02f4-0x4a0890, dark-gap raw disasm) is now
reconstructed: `BTMechPostCombatReports` + `BTMechPostVehicleDead` (btplayer.cpp), called from the
handler at the binary's exact positions (mech.cpp). Retires `BTPostDamageScore`/`BTPostKillScore`.
**Entry sequence** [T1]: gyro bounce → death-edge latch `[ebp-0x10]` (was-destroyed at ENTRY —
before the divert!) → `lastInflictingID` stamp (mech+0x43c ← msg inflictor) → shooter resolve
(registry find → `shooter+0x190` = shooter's PLAYER; victim's = `mech+0x190`) → **collision divert
JUMPS TO THE DEATH TAIL** (@0x4a0375 `jmp 0x4a07b5`, NOT a return — a wall/fall death still posts
VehicleDead + blasts, but skips the score blocks: collision deaths credit no one). Our old early
`return` here was a latent "wall-death strands the pilot" hazard, fixed with the move.
**The three id-0x16 reports** (all `Player::ScoreMessageID` 0x16, sizeof 0x3C — layout in
btplayer.hpp, static_assert-locked; `scoreAward`=APPLIED tally in all three):
- **A @0x4a04da, newly destroyed** → type 2 KillScore to the SHOOTER's player. Basis (+0x24) =
the VICTIM role's `killBonus` (role+0x1c). senderMechID = the victim. Suicide (eject charge,
self-damage) IS dispatched — the handler negates the award (@0x4c03ab `fchs`) and skips
`killCount++`: **the #134 panic penalty, live** (bench: `type=2 award=-39.00 kills=0`).
- **B @0x4a05d9, not newly killed && tally≠0** → type 0 to the shooter: the **per-hit INFLICTED
credit**, and it is LIVE. ⚠ **CORRECTED 2026-08-07** — this entry previously read "the ONLY
registered 0x16 receiver Verify-rejects type 0 → 1995 folded an UNINITIALIZED stack float into
the shooter's score on every non-lethal hit (real 1995 bug — @0x4c0200 … is in NO table entry:
dead code)". **That was wrong**, and build 787 retired the port's per-hit crediting on the
strength of it (the scoring regression players reported on 4.11.817). `BTPlayer` overrides
**`Dispatch` — vtable `@00513300` slot 3 = `FUN_004bffa0`** — and splits type 0 off BEFORE base
dispatch: `if (id==0x16 && type==0) FUN_004c0200(...); else base;`. `@004c0200` names itself in
its own Verify string (`BTPlayer::ScoreInflictedMessageHandler`) and computes
`CalcInflicted(basis) → negate if target==self → × (targetTonnage/ownTonnage) → += +0x278`.
`ScoreMessageHandler`'s type-0 arm Verify-rejects precisely BECAUSE the interceptor guarantees
type 0 never reaches it. Independently corroborated by the original manual's SCORING CHART
(`reference/manual/scoring_chart.webp`, via Lynx): "+1 each damage point scored on opponent's armor" and "-1 each
self-inflicted point of armor damage" — the negate-if-self arm exactly. Interceptor restored;
benched 83 inflicted rows, awards 0.98–25.00, zero type-0 Verify rejections. [T1]
- **C @0x4a06c0, tally>0 (kills included)** → type 1 DamageReceivedScore to the VICTIM's player.
Basis = INTENDED damage (burstCount×amount). senderMechID = the INFLICTOR. Feeds the received
penalty (`CalcDamageReceivedScore` returns the NEGATIVE) + the operator-console VTVDamaged line
(gated `GetConsoleHost()` && !`suppressConsole` — which is why that field is named that).
Reports carry the LOOP-ENTRY zone (msg+0x24, never rewritten mid-loop), the vital-wreck flag, and
`inflictingSubsystemID` (msg+0x5c, engine T0 name).
**Score model consequence** [T1, ⚠ REWRITTEN 2026-08-07]: 1995 pod scoring = **per-hit inflicted
credit + kill awards + received-damage penalties + death costs**. The previous text here claimed
"No per-hit inflicted credit … inventions riding the dead @0x4c0200 channel; both retired" — that
followed from the dead-code misreading corrected in report B above, and retiring the credit IS the
scoring regression reported on 4.11.817. The **original manual's SCORING CHART** (`reference/manual/scoring_chart.webp`)
is the cross-check for every row and should be consulted before touching this path again:
| Points | Event |
|---|---|
| +1000 | Starting the game |
| +1 | Each damage point scored on opponent's armor |
| +10..+30 | Destroying an opponent's internal system |
| +500 | Destroying an opponent's 'Mech |
| −1 | Each self-inflicted point of armor damage |
| −10..−30 | Knocking out one of your own internal systems |
| −500 | Destroying your own 'Mech by an ammo explosion |
| −1000 | Destroying your own 'Mech by ejecting |
⚠ **THE SCORE AUTHORITY IS THE OPERATOR CONSOLE, not the player object** [T1, 2026-08-07]. The
binary sends `ConsolePlayerVTVScoreUpdate(ownerID, currentScore)` every `CONSOLE_UPDATE_INTERVAL`
and then does `param_1[0x9e] = 0` — **ungated**. So `+0x278` is a *console DELTA*, never a running
total, and it does not matter which NODE computed a delta: every node's contribution is flushed
stamped with the scoring player's `ownerID` and the console accumulates. This is almost certainly
where the chart's **+1000 starting the game** was seeded, which is why no game-side code grants it.
**Consequence for the port** (no console as score authority): `GetScore()` (SCORE gauge),
`Player::CalcRanking()` and the replicated `Player__UpdateRecord` all read `+0x278` **on the owning
node**. Damage is applied on the VICTIM's node, so block B dispatches the inflicted report to the
SHOOTER's player object there — a **REPLICANT** — and the credit is banked on the wrong machine,
where the master's next update record overwrites it (benched: totals climb to ~35, snap back every
few seconds = the field "scoring is screwy"). ⚠ OPEN. **Tried and rejected:** gating the type-0
interception to `MasterInstance` so a replicant reroutes — the message arrives but the BT extension
fields (`damageAmount`@+0x24, `senderMechID`@+0x34) do NOT survive the wire, only the base
`scoreAward`, so every award computes 0.00. That is also WHY the kill report (type 2) already
credits cross-node correctly: its value rides `scoreAward`. **Fix shape:** compute the award on the
victim's node (where the damage data is) and ship the RESULT in `scoreAward`, as the kill report
does — do not ship the basis and recompute where it cannot be seen.
**The damage-bias term is VESTIGIAL — do not "finish" it** [T1, audit 2026-08-08]. The kill/inflicted
formula's `(victimAvgZoneDamage@0x354 × damageBias + 1.0)` factor is **always 1.0** in the shipped
binary. `mech+0x354` has exactly one writer — `Mech::Reset` (@0049fb74, part_012.c:14340), which
computes `mean(zone+0x158)` across every damage zone *after* the zone heal has zeroed those cells —
and exactly one reader, `CalcInflictedScore` (@004c052c). Nothing recomputes it during play, so it
holds ~0 for the mech's whole life. `0x358`/`0x35c` are the same computation over subsystem zones
and have **no reader at all**. The port's `MECH_DAMAGE_BIAS(m) → 0.0f` therefore reproduces the
binary exactly; wiring it to live damage would look like completing a stub and would silently
inflate every award (the chart-verified +1/point and +500/kill both assume 1.0).
⚠ **Three chart rows are NOT yet reconciled with the reconstruction** — treat as open [T4]:
(a) a kill benches at `award=4.88`, two orders off the chart's flat **+500**; (b) **+1000 at
game start** has no known implementation; (c) **−1000 eject / −500 ammo** would live in
`ScenarioRole::specialCaseDeathPenalty` (role+0x20), which the port reads
(`GetSpecialCaseDeathPenalty`, the death-cost block) but which **shipped content authors
nowhere**, so it is 0 in the field — the #134 symptom by another route. Do not "fix" these by
hard-coding chart numbers; find where the binary sources them.
Kill award = `(victimKillBonus + tally) × killerRole.damageInflictedModifier ×
(victimAvgZoneDamage@0x354 × damageBias + 1.0) × (victimTonnage/killerTonnage)`; same-team kill in
a non-FFA game = `-friendlyFirePenalty` basis (inline strcmp of `teamName@0x20c`, gate
`freeForAll@0x250==0`); self-kill negates the whole award.
**The death tail** (@0x4a07b5, shared by the divert): gate = was-alive-at-entry && movementMode
9|10 → **`Player::VehicleDeadMessage` id 0x17 to the mech's OWN player** — the respawn trigger,
in the BT 0x38-byte extension `{deathCount -1, dropZone Null, +0x2c killed-by PLAYER EntityID,
+0x34 kill zone}` (bench: `killedBy=2:1 zone=3` cross-node) — then the death Explosion (id 3,
0x5C, model 0x31; port fires the authored death list from the transition instead, #42) and the
#89 SplashDamage (re-verified after the reorder: 72 bursts at ~9u). The old mech4
death-transition dispatch site (which was flagged [T3 sender-undecoded]) is retired — this IS
that sender. The #55 NULL-playerLink fallback + DEAD_NOTIFY forensics moved into the bridge.
Benches: `scratchpad/night12/scorekill.sh` (cross-node kill: killer `kills=1 award=4.88`,
victim respawns, death #1 single-cycle) + `scoreself.sh` (#134 negation). Collision-death tail
fallthrough is inspection-tier [T3] — shares the benched tail code; field wall-deaths exercise it.
## (HISTORICAL — the gap as found 2026-07-29, superseded above) [T1]
The authored crit machinery exists and is reconstructed — `Mech__DamageZone::CriticalHit @0049ccc4`
(half the damage to armour, half to ONE critical subsystem chosen by `criticalWeight`, capped by
`damagePercentage`) — but **nothing in the port calls it**. Raw byte-scan of the binary: exactly ONE
call site, `@0x4a0461`, inside the **un-exported gap** (no decomp covers `0x4a03xx-0x4a05xx` — the
same dark region as the `0x37c/0x388/0x38c` pick writer), so the crit TRIGGER CONDITIONS (per-hit
chance? threshold crossing?) are unknown and unreconstructed. Second layer:
`MechSubsystem::TakeDamage` is an **empty bring-up stub** (`btstubs.cpp:179`), so even a wired
caller would measure a delta of 0 through `ApplyDamageAndMeasure` (and the weapon-family overrides
chain to the engine base whose private-zone write is the zero-`damageScale` no-op — see the
subsystem-zone finding above). Net: **the Critical view lights ONLY on zone destruction
(`SendSubsystemDamage`, direct pin) or ammo cook-off (`DistributeCriticalHit`, direct pin), never
from accumulating fire.** The DISPLAY is fine — the paper doll shows ZONE ARMOR, the Critical panel
shows SUBSYSTEM crits (different data by design); the panel's near-permanent emptiness is the gap.
Field signature (night 6, Conn Man): "Armor panel damage. Critical damage display did not show any
crits." **#28 (vital-subsystem-crit death path) is very likely blocked by the same missing caller.**

**KEY FACT [T1]: `DamageZone::TakeDamage` (arcade `@0041e4e0` == WinTesla `DAMAGE.cpp:379`) is
`damageLevel += damageAmount * damageScale[type]` and IGNORES `burstCount`.** So ONE arcade cluster
Missile per trigger (damageAmount = authored/missileCount, burstCount = missileCount) applies its hit
EXACTLY ONCE to a zone — `burstCount` is cosmetic for zone damage (only the gyro-bounce math
`gyro.cpp:834` and the SplashDamage falloff `damage.burstCount/dist^exp` read it). The port
`damageLevel += damageAmount * damageScale[type]` and IGNORES `burstCount`.**
⚠ **CORRECTION (2026-08-01, #95): do NOT generalise that into "burstCount is cosmetic for zone
damage" — the earlier wording here said exactly that and it is WRONG.** `TakeDamage` ignores it;
the **CALLER honours it**. `Mech::TakeDamageMessageHandler` (@0x4a0423-0x4a04d8, reconstructed in
`mech.cpp` under task #80) loops `burstCount` times, calling `TakeDamage` once per burst and
**re-rolling the struck zone each iteration** (@0x4a04b9) — so a burst SPRAYS across zones.
`burstCount` is therefore "number of applications", and it is load-bearing for missiles (cluster
count), splash (distance falloff) and the gyro bounce alike.
So ONE arcade cluster Missile per trigger (damageAmount = authored/missileCount, burstCount =
missileCount) delivers its salvo through that loop, not in a single application. **How many of the
cluster connect is ROLLED at impact** in `Missile::Perform` right before dispatch
(part_013.c:10082): `b = Random(n) + n/4`, clamped to `n` — between a quarter of the salvo and all
of it. **And the arcade Missile dispatches DIRECTLY at the struck entity** (`FUN_004be078`:
`param_2->Dispatch(&msg)`) — it does NOT route through the shooter's `SubsystemMessageManager`,
whose consolidation would drop `burstCount` (`DamageInformation` carries only damageType +
subsystemID). Routing a projectile through the manager therefore silently deletes the cluster
count — that was the #95 bug, and it also produced the #84 double explosion. The port
re-expresses that ONE cluster as N flying `BTProjectile` rounds (visual tracers), and task #62

## The zone DESTRUCTION CASCADE is live -- an arm takes its gun (#110, 2026-08-02) [T1 decomp / T2 verified]
`Mech__DamageZone::RecurseSegmentTable @0049cad4`: when a zone reaches damageLevel
1.0 (non-leg, non-vital path in TakeDamage), the binary walks the mech's SEGMENT
TREE (mech+0x300, the engine `JointedMover::segmentTable` [T0]):
* `destroySiblingsOnDestruction` (streamed, Wword 0x68) -> every other zone on
the SAME segment (`EntitySegment::damageZoneTable`, seg+0xD0) recurses and is
set graphic state 2 (**Gone**);
* `descendOnDestruction` (Wword 0x67) -> every zone on every CHILD segment
(`childIndexTable` seg+0xE8 -> child's damageZoneTable) recurses -- **the arm
takes the gun pod with it**. Each recursed zone's `SendSubsystemDamage
@0049c9a8` pushes the unused crit allotment and `ForceCriticalFailure`s any
subsystem driven to 1.0 -- which the #86 fire gates then refuse.
Authored (measured, ava1): descend=1 on the four arm zones (2/6/9/17); everything
else 0. Verified live: dz_rarm destroyed -> zone 17 cascades -> AFC100 + bin +
Condenser6 force-failed, `AFC100 -> NoAmmo (gate1): destroyed=1`; dz_larm -> PPC
force-failed, `[emitter] 'PPC' fire REFUSED (destroyed=1)` x4998. Torso weapons
unaffected. Re-entry note: every further hit on a 1.0 zone re-runs the cascade
(no guard in the binary's child loop; only the sibling loop checks graphic state
!= 1) -- authentic, idempotent in effect.
⚠ The walk was a SILENT STUB until 2026-08-02 (three shim types whose iterators
returned NULL) -- the cascade "ran" and touched nothing, which is why blown-off
arms left firing gun pods across every chassis (Conn Man's three-chassis audit).

## Zone-LEVEL replication -- the observer's picture (#87 root cause, 2026-08-03) [T1 decomp / T2 verified]
How an OBSERVER (replicant holder) learns a mech's zone damageLevels, end to end:
1. Damage messages do NOT echo locally: `Entity::Dispatch` on a REPLICANT
forwards to the master's node and returns (ENTITY.cpp:244) -- there is no
broadcast-bus application. The MASTER alone consumes `TakeDamage`.
2. The master ships levels via zone UPDATE RECORDS
(`DamageZone::Write/ReadUpdateRecord`, `DamageZoneUpdateModelBit`), gated by
`ForceUpdate(DamageZoneUpdateModelFlag)`.
3. **Who raises the flag (the binary's effect watcher `FUN_0042aa2c @0042aa2c`,
the BT analog of the engine's `EntityEffectWatcher` -- which itself never
runs for mechs: mech zones carry BAND DESCRIPTORS, the engine `ExplosionTable`
stays NULL and `EntityEffectWatcher` is constructed nowhere in the image):**
* level branch (zone changedFlags & 4): if the rise CROSSES a band-descriptor
threshold (`FUN_0042a5f4` = `Mech__DamageZone::DescriptorCrossed`) AND the
entity is a MASTER (`(entity+0x28 & 0xc) == 0`) -> `*(entity+0x18) |= 2`
(= ForceUpdate(DamageZoneUpdateModelFlag)).
* gstate branch (changedFlags & 8): ForceUpdate unconditionally (masters).
So observers track a fight at **band-crossing granularity** -- not per hit.
4. Consumption on the observer is passive: `ReadUpdateRecord` writes the level,
the armour watcher (`TickArmourDamage`) re-reads zones every frame and pushes
the draw-op tint; the doll gauges read `damageLevel*100` continuously.
**The port had dropped the level branch** -- mechdmg.cpp's band hub ForceUpdated
only on `graphicState != Exists`, so every observer's copy sat at 0.0 until a
zone DESTRUCTED: no enemy hull darkening, no observer-side doll movement, ever
(the "no armour discoloration" night-10 report). Restored 2026-08-03
(mechdmg.cpp band loop: `DescriptorCrossed(prev, level)` + master gate on both
branches). Verified 2-node: A-side watcher pushed 114 level changes; every
replicant peak matched the master's final level to 4 decimals (dtorso 0.9321
both sides).
Render-path note (gotcha #23 discharged): the tint itself was pixel-proven with
`BT_ARMOR_FORCE` A/B captures -- all-zones 1.0 renders the hull charcoal (0.1x
floor), forced 0.4 reads visibly grey at close range on a light skin, so "no
discoloration" was never the renderer. Solo/master-side perception is the
authentic ECONOMY: 2-25 pt laser events vs 68-185 pt zone pools. The eye
catches SNAPS, not creep: a single heavy hit (ERLG large laser / missile
class, amt=25) jumps a 77-pt arm 0 -> 0.3247 in one frame (measured live) =
the pod veterans' "a single missile leaves visible armor damage"; 2-pt ERS
fire creeps ~1.6%/hit and stays visually silent for a dozen hits (the
"legs never show" reports -- their levels peak ~0.08-0.13). The cockpit doll
maps all 28 zones (L4GAUGE.CFG:4788-4814 cmArmor lines -- feet + lower legs
included); nothing is unwired (orphan audit 2026-08-03: every drawn op with a
material name is claimed by a zone).
Fidelity boundary [T1]: the HOST binary's response is LINEAR (watcher
@004573e4/@00457784: 13 material floats lerped toward x0.1 by level, then
"flush_material" to the division card). The CARD-side material->ramp->texel
curve is i860 firmware absent from BTL4OPT.EXE -- see [[open-questions]]
"i860 DIVISION-CARD firmware". If pod darkening was perceptually steeper at
mid levels, that steepness lived there.

code involved; grammar = the binary ctors @0x49ea48/@0x49e5e4). Results:
* **18 streams, 8 distinct by content** (copies 3,3,2,2,2,2,2,2). All 7-layer.
* **Slice counts are authored, not fixed 8**: Black Hawk band 6 and the
Vulture/Battlemaster band 4 are **7-wedge** rings; everything else 8.
* rotateWithTorso: layers 3-6 on six tables; **all-zero on Black Hawk + Owens**.
* Chassis -> content hash (live-dump matched, dump-identical rounding):
ava1->1b9958b4, bhk1->5150f823, lok1->b0a0e692, **mad1->c02bfc7a**,
own1->f0f03c87, snd1->0e1a9ca0, thr1->0163740f, vul1->739b1a6b.
The two same-zone-set "Avatar/MadCat" tables ARE distinguishable by loader:
**the Mad Cat rides one (c02bfc7a), the Avatar the other (1b9958b4)**.
* **Wedge orientation, from the AUTHORED slice names** [T1 data]: W0/W7 =
"Right*", W1/W2 = "Front*" -- with theta = atan2(z,x) from +X toward +Z, the
mech-local FRONT is the **+Z arc (theta 45-135 deg)** and dead-ahead is the
W1|W2 SEAM. (Corrects the earlier #92 comment that put frontal hits in W6.)
* **⚠ PORT FRAME ADAPTER (#124, fixed 2026-08-03; corrected same day by the
MUZZLE-ANCHOR probe)**: that +Z-forward (and +X-right, from the W0/W7
"Right*" names) is the **1995 resolver frame**. OUR engine frame, measured
with the mech's own asymmetric geometry as the anchor (`BT_ASPECT_TEST`:
four world-cardinal self-impacts + one at each weapon's physical muzzle):
**RIGHT = +X, same as 1995; FORWARD = −Z, flipped** — the LEFT missile pod
sits at raw local x=−2.32, the RIGHT at +2.32, and `WorldToLocal` is a clean
R(yaw) with no hidden terms (verified at yaws −30°/150°/40°). The frames
differ by a **Z-NEGATION ONLY — a reflection** (the first commit's π
rotation CROSSED the pods: the left muzzle resolved rtorso). `ResolveHit`
negates local z; and because a reflection reverses angular direction, the
torso-twist term in `SelectSlice` enters with the OPPOSITE sign (twist was 0
in every probe — the twisted-torso verify is the tracked follow-up).
Anchor acceptance: left pod→ltorso, right pod→right wedges, left/right arm
muzzles→larm/rarm, nose→front cells, tail→rear cells, at a third yaw. The
separate "one band LOW" Y-signature is #16 (pick-ray parallax), not this.
Frontal unaimed foot-band hits therefore straddle the RightFoot/LeftFoot
cells by impact-x sign, and the authored cross-bleed (20% opposite foot,
10+10% opposite leg) is a data-true source of "hit the opposite leg" reports.
* Resolver mechanics re-confirmed from the decomp (@0049eb54/@0049e678/
@0049de14): WorldToLocal; local y CLAMPED to [0, heightRef] BEFORE scaling
(heightRef = live collision cylinder, owner+0x2ec->+0xc); layer floor+clamp;
atan2(z,x) +2pi wrap, on-axis -> random angle; rotateWithTorso adds the live
torso heading (torso+0x1d8) BEFORE slicing; uniform roll vs ascending
cumulatives, -1 fallthrough. **Collision damage (type 0) NEVER reaches the
cylinder** -- diverted at the handler head (0x4a0361: test type; 0x4a036d:
call 0x49ffcc; jmp out) [T1 disasm].
## The death transition is SYNCHRONOUS within the damage pass (2026-08-11) [T1/T2]
The binary writes movementMode 9 INSIDE the lethal TakeDamage pass — its own death-tail gate
(part_012.c:14761) reads 9||10 already flipped in the same call. The port deferred the write to
the per-frame UpdateDeathState and a same-frame direct+splash lethal pair re-ran the whole death
block (duplicate kill credit + duplicate VehicleDead) — caught by the 4-node bench, fixed by
running the once-per-death transition inline at the death tail (1b6d247). Full class write-up:
[[reconstruction-gotchas]] §25; stress verification: kd4_bench 9/9/9/9 + kd8_stress 26/26/26/26,
SWALLOWED=0 both. The receiver-side dedup remains a TRIPWIRE only (1995 has none; +0x290 never
written) — if it ever fires again, a new duplicate source exists upstream.
## Key Relationships
- Weapons/roster: [[subsystems]]. Aim source: [[locomotion]] (drive/facing). Effects: [[rendering]].
- P5 forensics: `docs/HARD_PROBLEMS.md`. Data: [[decomp-reference]] §4-5.
## The K/D-score AUTHORITY MODEL -- settled once and for all (2026-08-11, #162) [T1]
The 1995 chain has ONE emitter and NO receiver dedup; every counter is single-owner.
Fixed twice piecemeal (#150 kills, #162 deaths) before the full audit settled it -- do
not touch any single limb of this chain again without re-reading this section.
**Emitter (Mech::TakeDamageMessageHandler @0x4a0230 -- the victim's MASTER only;
replicant-asserted part_012.c:14613):** entry latch `local_14` = destroyed-at-entry
(modes 2|9, @0x49fb54). Three id-0x16 reports: **A** type-2 KILL -> shooter's player,
alive->dead edge only, exclusive with B (basis = victim role's killBonus, @0x4a0506);
**B** type-0 Inflicted -> shooter, non-lethal AND corpse hits (tally != 0); **C** type-1
Received -> victim's own player, latch-INDEPENDENT (corpse hits included; basis =
intended damage = bursts x amount). Death tail (gate `local_14==0 && mode 9|10`,
@0x4a07b5): exactly ONE **VehicleDead** (id 0x17, deathCount=-1, killer player id) ->
victim's own player, + explosion + delayed burn + splash (fresh TakeDamages, gate
advancedDamageOn && !suppressConsole) + ForceUpdate. Collision (type-0 damage) diverts
past ALL reports straight to the tail: a ram death counts + costs but credits no one.
**Consumer (BTPlayer):** 0x16 type-2 @0x4c02e4: CalcKillScore, killCount(+0x27c)++ dual
(the phantom wrong-column partner -- keep byte-faithful), suicide fchs negation skips
both increments. 0x17 @0x4c05c4 deathCount==-1 arm: deaths(+0x280)++ then STRAIGHT-LINE
the -500 cost (gate advancedDamageOn(+0x264) ONLY; -role->specialCaseDeathPenalty
(+0x20) via DIRECT Player::ScoreMessageHandler base call -- never on the wire, never in
a matchlog; the [deathcost] DEBUG line is its only receipt). **The receiver dedup gate
+0x290 is NEVER written non-zero anywhere in BTL4OPT.EXE [T1 image byte-scan]** -- the
binary's single-increment guarantee is purely the SENDER's one-shot edge. Its clear
pair (+0x290=0, +0x258=0) lives in the DropZoneReply tail (FUN_004c012c,
part_013.c:10519) -- the #81-era port put it in the VehicleDead arm by misattribution,
disarming the port's defensive latch (corrected 2026-08-11).
**Replication:** the player update record carries currentScore(+0x1c8) +
dropZoneLocation ONLY. killCount/deaths never cross the wire in 1995; each node's
scoreboard columns are locally accumulated (the port's SBMIRROR is a deliberate
deviation that makes boards consistent).
**Full evidence record** (every dispatch/arm/layout with decomp line cites, the field
receipt A/B, and the fix archaeology): `docs/KD_CHAIN_AUDIT_20260811.md`.
**Port rules that keep it correct:** (0) **the entry latch is MODE-based (movementMode
2||9 == FUN_0049fb54), NEVER the alarm-based IsMechDestroyed()** -- EjectPilot raises
graphicAlarm to 10 BEFORE its killBonus self-damage, so an alarm-based latch reads a real
punch-out as "already destroyed" and silently eats the suicide type-2 (the -499 arithmetic)
while cook-off suicides still score; caught by the eject canary 2026-08-11, the same
alarm-vs-mode trap #108 fixed for deathBlastArmed; (1) the report block AND the death tail
are both master-gated + entry-latched (mech.cpp) -- replicant-side damage application is a
visual-only deviation and must never emit; (2) advancedDamageOn comes from the mission
egg per-pilot page -- every stock egg stamps `advancedDamage=1` on every page, and the
FE egg writer now stamps the host's menu choice mission-wide (a memset-zero pilot
record shipped penalty-off for entire steam nights, #162); (3) the bench for ANY change
here is scratchpad/night15/kd_bench.sh -- five HARD invariants (deaths==increments,
cost-per-death, credit-per-kill, zero swallowed, arithmetic witness); its predecessor's
assertions were greps that matched nothing, which is how both halves shipped broken.

`p.range = len×1.3+60` distance-to-target cap was an invention — replaced by the
authentic time caps; (b) the pool's contact sphere tested UNGUIDED rounds against
the FIRE-TIME pick point and dispatched damage to the entity wherever it moved —
a locked AC/Gauss could not miss a moving target (bench: 86/86 "hits" vs a
circling mech). The pool now tracks the target's live position for the contact
test on every round kind; only guided rounds steer.

`DAT_004fd550`, btl4pb) → `MakeLinkedLamp(ButtonPanic 0x3d, 0x200000)`
(`FUN_00476fc0`) lights the pod PANIC button; on glass the pad panel shades
the miniconsole Panic button from the same PadRIO lamp state
(L4PADPANEL:295, verified lit dark→bright on generator kill). NO gauge in
the shipped L4GAUGE.CFG rides mode 0x200000 — the eject indication is the
BUTTON LAMP, not an MFD element ("weapon-eng MFD eject lamp" reports = the
weapon page's UNJAM/EJECT ammo-jam indicator, a different feature). Lamp is
SOLID on arm (engine linked-lamp semantic); FLASH = the GaugeAlarm
`SetAlertState` overlay (RIO::flashFast), not authored for panic. Port fix:
per-frame `EvaluateEjectPermission()` at the top of Mech::PerformAndWatch
(master-gated) + `GetEjectPermitted()` accessor; `BT_EJECT_LOG=1` logs the
arm edges. Adjacent table fact: id 0x1a `DuckRequest@0049fa00` latches
mech+0x398 = 1 — that latch has NO reader anywhere in the image (vestigial).
- **THE TECHSTATUS / GAUGE-ALARM MODEL decoded 2026-08-04 [T1]:** the gauge-alarm
"condition" = a **STATUS-FLAG BIT INDEX** (0..6, TechStatusTypeCount). MechTech's
`TechnicalAssistance` edge-scans every monitored subsystem's `GetStatusFlags()`
(vtable +0x30) and on a bit flip calls `ReportStatusSet/Cleared(sink, owner, sub,
bitIndex, alarmModel)` → `GaugeAlarmManager::Activate(condition=bitIndex)` → the
SHARED 'mechalrm' stream's items matching that condition flash their lamps
(SetAlertState → RIO flashFast). The bit table, all byte-grounded overrides:
**bit 0** structure ≥ StatusThreshold (@004ac18c) | **bit 1** structure >
StatusFloor | **bit 2** coolantActive && HeatModelActive (CoolantLeaking) |
**bit 3** heatAlarm ≠ 0 | **bit 4** linked AmmoBin cookOffArmed (**AmmoBurning**)
| **bit 5** weaponAlarm == 5 (**Jammed**) | **bit 6** !HasVoltage (no usable
voltage; `HasVoltage` = source stateAlarm==2 Ready && |outputVoltage| > ε,
@004b0b5c). **Invite semantics:** conds 4/5 → gotoEngineering 0x80 + engEject
0x85 = the AMMO purge/unjam invite (flashes the very key whose streamed function
is EjectAmmo msg 0xB) — NEVER pilot eject; cond 6 → 0x80 + engBusMode 0x86 =
the bus-switch invite; cond 2 → the coolant loop/placement lamps (#98). The
PANIC LAMP (mode-linked, solid) is the SOLE pilot-eject indicator. **Electrical
subtlety [T1, @0049c9a8 + FUN_004b1f7c]:** the crit distributor touches nothing
electrical, and the generator sim has NO Ready-case recompute — a generator
destroyed IN PLACE keeps stale Ready voltage (no bit-6 invite) until any
transition (thermal trip → stateAlarm 4 GeneratorOut, short, switch-off)
recomputes output via `(1 − damage) × rated` and zeroes it. stateAlarm 4's
producer = the THERMAL BREAKER in GeneratorSimulation itself; a 2026-08-03
destruction→state-4 bridge was removed as unfounded.
- **Generator trip/recovery + the warning edge (#154 audit, 2026-08-11, all [T1] unless
noted).** Trip: heatAlarm==FailureHeat(2) → stateAlarm 4, i.e. T > FailureTemperature;
recovery gate (case-4 body @4b1f7c) = heatAlarm back to **NormalHeat(0)**, i.e.
T ≤ DegradationTemperature — then 4→0 Starting → StartTime spin-up → 0→2 Ready.
Authored generator temps (raw BTL4.RES): start=77, degradation=**1000**,
failure=**2000** on all six vehicles — recovery at exactly HALF the trip line;
manual p23 prints the half-way rule verbatim, and the heat bar's colored fill
(VertTwoPartBar @4c48fc) exists exactly while T > 1000, so "red gone" == the
recovery gate to the tick. NO hysteresis in the heatAlarm ladder (@4ad924).
**The warning edge is authored backwards in the shipped content**: BTL4.RES
streams exactly TWO AudioStateTriggers per generator on GeneratorState —
(trigState=1 Idle, inv=0, Start) and (trigState=4 GeneratorOut, **inv=1**, Start,
= fire on LEAVING 4). No enter-4 trigger exists (RES-wide census: 144/144 rows,
triple-verified decode + live [audioedge] capture). Consequences, ALL live-benched
(`scratchpad/night15/gen_edge_bench.sh`, receipts BT_AUDIO_EDGE/[audioedge] +
BT_GEN_HEAT injection): thermal trip 2→4 SILENT; natural recovery 4→0 FIRES the
warning; respawn-with-tripped-gen RTIS (4,0) FIRES it (ghost warning during
respawn); crit-death fires enter-Idle one frame late; 4→1 (cooled while switched
off) double-fires. The generators' inv+Start is the ONLY inverse-Start fault
trigger in the game (census) — a 1995 authoring slip [T4 intent]. Port machinery
is faithful end-to-end. **DELIBERATE DEVIATION shipped 2026-08-11 (user-approved):**
the AudioStateTrigger ctor (AUDWTHR.cpp) flips the GeneratorState (trigState=4,
inv=1) record to inv=0 at stream time — warning now fires at the TRIP, silent at
recovery/respawn; `BT_GEN_WARN_SHIPPED=1` restores shipped behavior. This is the
port's ONLY authored-content override (precedent: the self-hit score deviation).
**The warning IS a VOICE — CORRECTED 2026-08-11 (a same-day wrong claim swept):**
the Warnings01/AllWarning zones are the project's recorded voice material (Yip,
original VWE) and the AudioControlSequences chain the zone-WORDS into spoken
phrases — established by the #119 leak-voice work (commit 42b0691: "the warning
is a phrase-sequenced voice patch (Warnings01 zones as notes)"). The generator
sequence (notes 29/16/26 = zones z4/z0/z3) is the spoken "generator out" phrase —
**ear-verified 2026-08-11** (zones played in sequence order, rate-patched copies) [T2]. An earlier revision of this entry claimed BT 4.10 shipped no speech and
attributed era memories to Firestorm — WRONG: the claim rested on preset NAMES
and was contradicted by our own git history. With the voice real, era memories
of hearing it at the trip may be genuine (possibly a later floor-content
revision fixing the same bit our deviation flips).
⚠ Process lesson: before asserting an asset ABSENT, grep the project's own git
log and prior tickets for the asset family (#119 was one `git log --grep=voice`
away; six audit agents and the synthesizer all missed it).
Voice-steal note: night-15 field logs show up to 932 channel steals/session — even
fired Starts can be eaten at combat peak (L4AUDRND weight-steal).
Diag hooks: BT_GEN_HEAT=<units/s> (+_DELAY/_SECS) injects into viewpoint
GeneratorA (thermalMass=726000 raw units — rate ~1.5e8 for ~18-25 s trips it);
BT_AUDIO_EDGE=1 prints every state-edge trigger delivery FIRED/no-fire.
Related corrections: AmmoState 3 = EJECTING (an earlier lane's "cook-off enter-3"
label was wrong — cook-off warning rides FireCountdownStarted matchers); manual
p23 also answers #133: the MFD X = generator destroyed by CRIT, not overheat.
- **THE CONDITION FLAGS ARE ROUTINE, NOT ALARMS — field-verified 2026-08-08 [T2]:** a
`[techstat] <sub> condition <n> SET` is an *operating* flag ("this component is above
nominal / browned out RIGHT NOW"), not a fault report. Census over a full Steam match
(`steam_20260806_c_michael_XIAOLONG.log`): cond 3 **Overheating** fires 33× on LLaser_2,
31× LLaser_1, 26× SRM4, 18× PPC_2 — every weapon trips it on each volley and clears it on
cooldown; cond 6 **BadPower** fires 8× on Myomers, 3× each on SLaser_1/PPC_1/MLaser_1 as
the bus browns out under simultaneous draw. **Every subsystem's SET/CLEARED counts are
balanced** (GeneratorD 5/4, GeneratorA 8/7, Myomers 5/4, Condenser5 1/1 — the odd extra SET
is only the log ending mid-heat). Nothing latches. **Never read a post-respawn `condition 3
SET` as a reset failure** — that inference cost a full two-sided reset audit (#137 below).
Diagnose a heat complaint from the SET/CLEARED *balance* and the throttle state, not from
the presence of a SET.
- **#137 "respawn came back with MYOMERS heat MAXED" = NOT A BUG, closed 2026-08-08 [T2]:**
`Mech::Reset` is clean on both sides — bench: every roster subsystem incl. all six
Condensers at `T=77 start=77`; field log: every live condition CLEARs 12–16 lines after each
reset. The heat is real and immediate because **the mech respawns still under power**: at the
reset the log reads `thr=1`, `cycleSpeed=14.6`, gait state 12 (running), and the myomers →
Condenser5 → GeneratorD trip Overheating within ~1–2 s. `Mech::Reset`'s subsystem loop starts
at **index 2** and the ControlsMapper is **index 0**, so the throttle is never reset — and the
binary does the same, which is correct for a pod whose throttle is a PHYSICAL lever still
under the pilot's hand. **Desktop caveat (real, and separate):** the glass bridge emulates
that lever with a file-static ramp accumulator `sLever` (mech4.cpp:3250), zeroed ONLY by the
X all-stop and a direction-crossing snap — so a pad/keyboard pilot, who is physically holding
nothing, likewise respawns at speed with the lever state invisible. Port-layer question, not
a heat bug.

`@004c07cd-0x4c0828` (inside the @004c05c4 export gap — missing from the #52

Direct call, NOT dispatched — bypasses the BT handlers' type Verifies. NUANCE [T4]:

that sentence was wrong on both halves.** The role's scoring fields are not authored via
notation keys at all: the ctor `@00429a9c` loads them from the role MODEL's GameModel

## THE ENGINE FRAME-RATE GLOBAL — `DAT_0052140c` = 28.0f (2026-08-02) [T1]
The DOS binary's per-frame<->per-second conversion scalar, set ONCE at startup:
0x401ace: mov [0x52140c], 0x41E00000 ; 28.0f (nominal rate)
0x401ada: mov [0x52140c], 0x4191A6E0 ; 18.2065f (BIOS-tick fallback, PIT/65536)
and passed straight into the ApplicationManager ctor by the DOS main
(0x401189: `push [0x52140c]`). ~90 code sites `fmul`/`fdiv` this global —
whenever the decomp shows an unexplained multiply/divide by `_DAT_0052140c`,
it is per-second <-> per-frame conversion at the pod's 28 Hz.
**The AUDIO/EFFECT FRAME CLOCK is this same rate.** `AudioTime::
Seconds_To_Frames` in the image is `fmul [0x52140c]; fadd 0.5; round` (e.g.
@0x42c611, @0x42dd86 — the 0x42xxxx audio-layer cluster of the ~90 consumers),
so every authored audio duration/delay counts frames at 28. WinTesla's
`DefaultRendererRate` said **30** — all audio timing ran ~7% fast until
corrected (2026-08-02). Oracle's coupled report ("prolonged smoke and
explosion including sound") was the lead: effect visuals and audio share this
clock family.
**So the pod's nominal simulation cadence was 28 fps, not the i860 board's
30 Hz — and it was UNLOCKED.** Corroborated testimony (2026-08-02): Oracle —
the pod rate was "flipbook" territory, heavy fights "a slide show"; Lynx
(original era) — "BT never had a locked frame rate in 1st release testing",
RP targeted 30, Tesla 3.0 managed ~20 on a good day. The engine pacer design
agrees: fixed budget, background fill, NO overrun catch-up (APPMGR.cpp T0) —
target 28, allowed to slip. Consequence: any per-tick dt-LESS accumulator ran
SLOWER during heavy combat on real pods; per-tick behaviors must be calibrated
against the loaded effective rate (veteran bracketing), not the constant. Every "per tick with no dt" accumulation in the binary (the myomer
kinetic heat term; candidate: particle trail density) was calibrated against
28 nominal — and less under load (the 18.2 fallback existing at all says slow
paths were expected; the EFFECTIVE in-pod rate is an open question, see
[[open-questions]]). Our port's frame pacer note in btl4main.cpp claimed 30
as "the pod's authentic rate" — corrected to 28.

The lit cockpit buttons are drawn every frame (`BTDrawCockpitPanels`, reading `PadRIO::GetLampState`),
but the lamp STATE sweep that fills that store — `LampManager::Update` → `AssertNewLampValue` →
`SetLamp` — authentically rides `GaugeRenderer::ExecuteForeground`, which fires only **once per full
gauge cycle** (foreground→background→copy). The cycle can't advance to the next foreground turn
until the THROTTLED background gauge sweep drains the ~140-instrument active list, and that
background task starves under load (issue #45 — "instruments freeze while fps stays healthy"). So on
a busy MP mission the lamp sweep ran ~1×/s: **buttons froze / flashes stalled while the 3D view (a
separate per-frame foreground render) stayed smooth** — the "lighting slow or nonexistent" reports
(all testers on glass surround). Fix: `BTGlassSweepLamps()` runs the lamp sweep EVERY frame on the
dev/glass composite path (`L4VB16.cpp`, in `BTDrawGaugeInset`) — cheap (deduped pushes, ~72 lamps),
decoupled from the gauge cycle. The pod never enters this path (real gauge hardware), so its
bandwidth-paced serial lamp cadence is untouched. Kill switch `BT_GLASS_LAMP_SWEEP=0`. NB the RIO
serial/lamp stack itself is byte-identical to pod-proven Red Planet (`L4LAMP.cpp`/`L4SERIAL.cpp`

**THE CARET CAN DIE FOR THE WHOLE SESSION — #147, fixed 2026-08-08 [T2 code, T3 field link]:**
`sShownRange` (mech4's targeting step) is a **function-level static** — one cell per process,
shared by every mech, carried across drops. **NaN is absorbing** in `step = trueRange −
sShownRange; sShownRange += step`, and neither the producer's clamps nor
`BTReticleRenderable::Draw`'s (`range < minRange` / `range > maxRange`) catch it — both
comparisons are **false for NaN**. A poisoned value therefore reaches `AddPoint`/`ConcatMatrix`,
and the caret + its bar become **degenerate geometry that stops rendering while the static tick
marks keep drawing** — the exact reported symptom ("no range finder on this drop", ticks there,
caret gone), sticky until relaunch. Fixed four ways: re-seed on mech change (not on respawn —
that reuses the entity, and the binary doesn't reset the readout either), a producer NaN trap, a
NaN-safe consumer clamp falling back to the 1200 peg, and — the reason no log could settle it —
**`BT_RANGE_LOG` now prints the caret's actual input** (`[range] caret input shown=`). It never
did before: `BT_RANGE_LOG` instrumented the PICK (#4) and `[target]`'s `range=` is a *separate*
locally-recomputed Sqrt in the weapon-range check, so grepping field logs for NaN found nothing
because the poisoned variable was never printed. Causal link to the field report is INFERENCE.
**GAP — the 100 m RANGE BIAS is NOT reconstructed [T1 read, unimplemented]:** HudSimulation
subtracts `_DAT_004b7ecc` (100.0f) from `RangeToTarget@0x1EC` **every frame while the timed

## The gauge EXECUTIVE — why panels froze in MP, and the fix (#45 root, 2026-07-30) [T0 engine / T2 verified]
Instruments repaint via the BACKGROUND task pump (`APPMGR.cpp RunMissions`): after sim+render, the
loop pumps `BackgroundTasks::Execute()` (ONE task per pump, ~7 tasks round-robin: net, events,
audio, GAUGES, …) **only until the frame deadline** — the gauge renderer's turn advances **one
gauge** of the active list (`ProcessOneActiveGauge`, ~140 active), and the 16-bit `GaugeRate`
mask advances once per FULL sweep (so "rate D = every 4th frame" is really every 4th SWEEP).
On a busy MP mission the foreground eats the whole frame budget → 1 pump/frame → a full
instrument rotation took MINUTES at perfectly healthy fps: comms-panel K/D stuck at 0, recharge
tickers frozen — while the underlying tallies (and their replication) were exactly right. This
is the real root of the field "panels don't update in MP" (#45's display half).
**Fix (both env-tunable):** `BT_BG_MIN` (APPMGR.cpp, default 32, 0=authentic) guarantees a
minimum pump floor per frame; `BT_GAUGE_BATCH` (GAUGREND.cpp, default 32, 1=authentic) advances
a batch of gauges per gauge turn (a visit is only a rate-mask check unless due). Verified

## The COOLANT-LEAK ALARM audio chain — fully built; the shared-Stop is AUTHENTIC (#99, 2026-08-01) [T1 disasm-verified]
The audible leak warning is **implemented and works end to end**; an earlier note
claiming it was "genuinely unbuilt" was wrong (asserted without checking).
**The chain**, traced live (all probes under `BT_ATTRBIND_LOG`):
`HeatSink::coolantActive` (published as the `ReportLeak` attribute) changes 0->1
-> `AttributeWatcherOf<Logical>::Execute` sees it (`[watchpoll] CHANGE`)
-> `AudioMatchOf<Logical>::SendNotificationOfChange` fires (`[matchfire] val=1 -> ctl 1`)
-> `AudioControlSequence::ReceiveControl(StartAudioControlID)` -> `StartSequence`
-> an `AudioIdleWatcher` ticks it each frame (`IdleAudioControlID` -> `RunSequence`)
-> `[seqsend]` emits the authored pattern: two chirps then an ~8s sustained tone, looped.
**The authored wiring (BTL4.RES): 19 subsystems, ONE shared alarm sequence.**
`Condenser1-6, GeneratorA-D, Myomers, PPC_1/2, ERMLaser_1-3, SRM6_1/2, Avionics`
each bind TWO `AudioLogicalTrigger`s to their own `ReportLeak` — match 1 -> ctl 1
(Start), match 0 -> ctl 2 (Stop) — and every one of them drives the SAME sequence.
**Consequence, and it is AUTHENTIC:** any single subsystem clearing its leak sends
an unconditional Stop, silencing the alarm even while others still leak; the
still-leaking ones never re-assert because their flag has not *changed*. Reported
from the field as a bug ("was sounding, resolved a leak, but there was another").
**Do NOT 'fix' it** — verified in the arcade image, not merely inferred from the
engine source lineage:
| what | where |
|---|---|
| same MUNGA sources compiled in | `d: esla_bt\munga\AUDSEQ.CPP` / `AUDWTHR.CPP` strings present |
| object factory | `@00466184` `case 0x4b` -> alloc **0x5C** -> ctor `@0043ccec` |
| vtable | `0x4ead48` |
| `ReceiveControl` | `@0043d3a4` — switch on control IDs **1 / 2 / 9 / 12** = Start / Stop / Idle / Tempo (exactly our enum) |
| Stop case | `@0043d3ca` -> unconditional `call StopSequence @0043d2d4` |
| `StopSequence` | tests only its OWN `isRunning` (`+0x28`), then the Chase loop — **no refcount, no awareness of other leak sources** |
So the arcade had the identical structure. Silence in 4.11.674 was a different
cause: the OpenAL source pool was exhausted in every player session (see the audio
pooling fix) — an alarm that cannot acquire a source is silent.
⚠ The bench cannot confirm audibility: it runs with no audio device (`live=0
pooled=0`), so the control chain is verified but final playback is not.

Secondary / Radar=monitor:DISPLAY4,bare

The resolver (`ResolveMonitorSpec` + `MonScanProc`, `L4GLASSWIN`) matches the full device name OR
its tail, so `monitor:DISPLAY4` works without typing `\\.\`; a bare integer is a 0-based index in
enumeration order. The surface is CENTRED on that monitor. This is what makes a fixed rig
survivable: **desktop rects move** when a display is re-detected, a USB graphics adapter
re-enumerates or someone changes a resolution, and a pixel rect then silently puts a panel on the

its saved rect + `,noframe` via `BTGlassLayout_QueryWindow` (BEFORE sizing — `WS_POPUP`'s frame

**What the port was missing is the crash SELF-DAMAGE *and its own pricing path*** (two halves;
the first alone one-shot mechs on wall taps — corrected same day): the blocking branch (export
gap @4aa89f-4aaab4, `scratchpad/night6/gap_4a9770.txt`) fills `fallDirection`=worldToLocal(
dmg.damageForce) (FUN_0040879c = Mᵀv, un-normalized), `fallScalar`=−(fallDirection·localVelocity
.linearMotion), then **Dispatches `TakeDamageMessage{0x64, zone=−1, the collision Damage
verbatim}` at its own mech** (was the long-standing "DEFERRED" note; mech4.cpp). CRUCIALLY the
TakeDamage hub then **DIVERTS damageType 0 (@0x4a0368 → FUN_0049ffcc, gap disasm
`gap_49ffcc.txt`) — collision damage NEVER touches zone armor.** It is the manual's
"splash/collision damage" technician setting: gated on the player's advancedDamage copy
(+0x268), priced `raw × (2000/mass)/(100/3.6)²/(1−elasticity²)` (a 60-ton mech: ~4.5e-5 — a
wall tap prices ~0.05, and <0.5 is FREE), then split into 0.5-point RATTLE CRITS applied to
random internal subsystems (HeatSink family/Gyroscope/Torso, drawn by
`collisionCriticalHitWeight`@0x10C). See [[combat-damage]]. Verified: wall-grinding no longer
kills or heals the limper (0 deaths, 27 rattle events, mech stays gimped) and the peer's
replicant re-enters the gimp cycle between bounded staggers; grass circling unchanged (198).
**Falsified en route (do not revive):** (a) "the stagger's action-request flags feed a drive
suppressor" — image-wide + full-gap sweep shows `word[this+0x18]` is read ONLY by the net record
emitter; (b) "the bmp clip's ~6.5 u/s root motion presses back into the wall" — measured `adv=0
cycleSpeed=0` during state 0x20; the re-strike velocity is the REBUILT gg cycle; (c) "the gimp cap
is ±5.8 (so √40 sits just above it)" — that number is `gimpStrideLength`@0x350 (the BACK-cycle
figure, printed under a misleading label since renamed `ggCapL/R`); field @0x52c (`gimpSpeedMax`)
has NO binary consumer. Advance caps, loader fills, crunch path and crash branch are all verified
byte-faithful — the self-damage dispatch was the only gap. Replication detail in [[multiplayer]].
**The LAST #82 layer: the peer body-channel TRN-LOCK (root-caused + fixed 2026-07-30) [T2].**
After the storm fix, a CIRCLING limper still skated on peers (user repro): post-knockdown recovery
lands the peer at body-stand; the port's peer turn-step arming block (mech4.cpp `PerformAndWatch`,
needed because the peer no longer runs the leg channel that cross-arms trn) saw
`replMppr->turnDemand` (circling → always turning) and armed body state 4 — and NOTHING could exit:
(a) body case 4's speed exit read the LOCAL mapper's `speedDemand`, a **dead cell on a replicant**
(nothing writes it → 0 forever); (b) turning never stops for a circler. Peer pinned in trn
(advance-only churn = leg-lifty skating) while `bodyTargetSpeed` held the replicated demand
(~24 u/s full). Measured via `[replgimp]` (`bts=24.6 standSpeed=6.83 bodyState=4` in 168/171
samples) and a `_ReturnAddress` trap on `SetAnimationState(4)` (`[trntrap]`, BT_TRNTRAP → linker
map: ALL 60 hits from PerformAndWatch = the port's own arm, NOT the type-3 reader — the master
broadcasts clean gimp states). Fix pair, mirroring the leg twin's authentic precedence
(part_012.c:12013 — the Standing speed test outranks the turn test): (1) mech4 peer arm gated on
`!wantsWalk` (`standSpeed < bodyTargetSpeed || bts < 0`), exit trn when wantsWalk; (2) mech2 body
case 4 `bspd` reads `bodyTargetSpeed` on ReplicantInstance (the replicated demand — the same
number the peer Standing case walks on). Verified: arena circle replicant 218×state-24/0×state-4
(was 116×trn churn), grass circle 235-clean, knockdowns bounded, 0 deaths. **Lesson: on a
replicant, every `MechControlsMapper` demand cell except those explicitly re-derived
(`turnDemand`) is DEAD — any peer-side state machine judging a local mapper read is judging 0.**
**The #52 SEQUEL: the peer body-channel STANDING-LOCK (root-caused + fixed 2026-08-07) [T2].**
Fixing (2) above closed an ACCIDENTAL escape hatch and the skate came back in a new shape. The
port's body case 4 is an INSERTION (the task-#64 lockstep twin) sitting between case 0 and the
advance group — but in the binary `case 4` is a **member of that advance group**
(`FUN_004a5678` @004a5678: `case 2,3,`**`4`**`,5,8,…`, no turn block, no speed exit) [T1], so
case 0's fallthrough is supposed to land on `Advance()`. The insertion intercepted it. On a
REPLICANT that is fatal and not a race: case 0 arms walk iff `standSpeed < bodyTargetSpeed`, and
the inserted block's exit tests `standSpeed < bspd` where `bspd` **IS** `bodyTargetSpeed` on a
replicant — the *same expression*. Arm and reset therefore fire on the same frame, every frame,
and a peer parked at Standing with a live replicated demand can never start cycling (reverse
likewise: both sides test `< ZeroSpeed`). Before e91d447 the replicant branch read the dead mapper
cell (0 forever) so the exit never fired and the fallthrough worked by accident. **Fix:** case 0
`goto advance_body_normally` — the leg twin's own idiom (`goto advance_normally`, mech2.cpp) —
restoring the binary's structure without touching the #64/#82 turn logic. `BT_NO_BODY_FALLTHRU=1`
reverts. Measured: legacy 336 consecutive locked seconds with `bspd=39.2324 bts=39.2324` identical
on every line; fixed 0 locks across every pass; the MASTER's body-Standing samples also fell 52→21
(it was locking too, invisibly — mj=0 writes no joints, and its two tests read *different* cells so
it only stalls in the window where they disagree). Turn-in-place re-verified under the fix (pivoter
reached body state 4 ×9 / leg state 4 ×8 — armed in lockstep).
**Why a peer must be able to self-arm walking at all** (the load-bearing bit behind
`mech4.cpp` "stand; case 0 walk-begins next tick"): the peer's body state is set directly from
`record->legState` only on **type-3 edges** (`ReadUpdateRecord`), and entering Standing emits one
while *leaving* it does not. So between gait-change records a replicant is REQUIRED to derive
walking itself from the replicated `bodyTargetSpeed`. That is why the lock needs a mech holding a
*steady* demand — a mech whose gait keeps changing keeps getting rescued by records, which is why
free-walking and wall-jammed benches each reproduce only half the symptom. [T2]
⚠ **The field symptom link is [T3], not T2.** The Standing-lock is proven and proven removed; that
it accounts for the night-13 episodes is inference (a locked peer has `bodyCycleSpeed==0` and never
advances its clip, so locked + translating *is* the `[skate]` signature by construction) — but no
bench caught the two together. The `[skate]` line now carries `bstate=`, so the next playtest
settles it: episodes gone → confirmed; any survivor names its own state. **NB the night-12
`skatebench` "reproductions" were a DETECTOR ARTIFACT** — the first detector build tested only
`legCycleSpeed==0`, which is normal on a peer (the body channel poses it), so it fired on every
healthy movement phase. Old-format lines (`legCycleSpeed=`, no `bodyCyc=`) are not evidence.

The manual's CROUCH button (streamed 0x13; glass key F4), end to end: DuckRequest (mech id 0x1a
@0049fa00) latches duckState@0x398 -> the master posture block (mech4, from the dark master-perf

myomer-alive gate) -> standing: SetLegAnimation(2) ('sqd', squat down; LegClipFinished case-2
PARKS the pose + leg alarm 1) / ducked: SetLegAnimation(3) ('squ', rise; case-3 alarm 0);
stability alarm flips; ForceUpdate(8)+(1) ships the type-3 state record -- peers pose the squat
for FREE (screenshot receipt: the crouched crimson madcat from the observer's cockpit,
duckmpA_031). Clip data verified from BTL4.RES (root joint drops -2.22, knees +-1.14; squ/sqd
are exact mirrors; interior 'squi/sqdi' variants ship for all 8 chassis). Full solo cycle
benched (BT_BTNTEST + BT_BTNTEST2): squat -> hold (joints steady for minutes) -> rise ->
standing zeros. Myomer factor: LIVE, not deferred -- the 2026-08-05 "feeder unreconstructed" claim was an
export-gap-blind grep (the members are NAMED: speedEffect@0x31C, myomers.cpp; the chain walk +
speedDemand scale + turn freeze = mechmppr.cpp:990, the 2026-07-31 seek audit, same bytes).
mechmppr now publishes the chain MAX into mech->myomerEffectiveness (the binary's +0x79C home)
so the crouch gate reads the live value: dead/overheated myomers (the Oracle seek-4 freeze)
refuse the squat AND the rise.
The pilot's EYE drops too -- the task-#15 bob channel (gBTEyeBobY <- jointlocal.y each frame)
carries the parked -2.22 into DPLEyeRenderable (log receipt bob=-2.2187 through the hold; frame
receipt duckcp_030 = grass-level view). A false "eye does not drop" residual was briefly filed
2026-08-06 -- measurement error (canopy-dominant diff crops; the canopy drops WITH the eye, so
the interior looks unchanged and only the through-window ground shifts). Bench traps for reruns: MP button delivery can miss if pressed
during round-start jitter (press >= poll 900 after GO); diags all BT_DUCK_LOG-gated.
### CROUCH addendum -- the #60 re-export pass (2026-08-06) [T1]
The rebuilt export (93.5% coverage) produced pseudocode for the master-perf region this block
was hand-disassembled from, and it **confirms the transcription field for field**:
`param_1[0xfe]`=mapPosture(0x3f8), `[0xe6]`=duckState(0x398), `[0x161]`=squatCapable,
`[0x1e7]`=myomerEffectiveness(0x79c), `[0x10]`=movementMode, `player+0x25c` novice gate,
`FUN_004a7fc4(2|3)`=SetLegAnimation sqd/squ, `FUN_004a4c54(8)+(1)`=ForceUpdate, `+0x131`
stability alarm, duckState cleared after. (Ghidra renders these as int-ARRAY indices --
`[0xfe]` == byte 0x3f8 -- which is why an offset-string grep of the export misses them; see
[[reconstruction-gotchas]] §20.)
**It also caught a branch the raw pass missed** (the hand disassembly stopped at `0x4aa0af`):
an **AIRBORNE AUTO-RISE** immediately after the duck consumer --
`if ((movementMode == 3 || movementMode == 4) && legState == 1) -> SetLegAnimation(3) +
ForceUpdate(8)+(1) + stability 1`. A mech that leaves the ground (jump/knockback) while PARKED
in the squat is forced upright; unconditional on duckState/squatCapable, i.e. a safety
un-crouch rather than a request. Implemented in mech4.cpp the same day; crouch re-benched
un-regressed (squat still holds on flat ground, no spurious rises).

## Myomer drive + the GIMP (limp) chain — COMPLETE 2026-07-30 (#75/#78)
The speed-demand site (`mechmppr.cpp` InterpretControls) applies the **drive scale**:
`speedDemand *= myomers.speedEffect`. The myomers factor is the wrapper's live 0..1
output (gear/thermal/1−damage, via `BTMyomersDriveOf`); the authentic coupling attached
`&speedEffect` into the mover's feed roster, which the 2007 engine lacks — the multiplication at
the demand site is the port equivalent. The GIMP chain: `mechdmg` raises **graphicAlarm 3 (left)
/ 4 (right)** when a leg zone (the `LegDamageZone`-flagged zones; MadCat: 3/5/8 left, 10/16/19
right) crosses `LegHalfStructure` (0.5), and **reverse input is refused** ("reverse disabled",
`[gimp]` log — and the binary agrees: the gimp gait machines have NO standing→reverse entry).
⚠ Cross-TU reads of the gimp level MUST use `BTMechGimpLevel` (mechdmg.cpp) — see
[[reconstruction-gotchas]] §23 (the AlarmIndicator typedef split). Harness:
`BT_SELF_DAMAGE_ZONE=<n>` ramps one zone deterministically; `BT_DRIVE_LOG` prints
`[drive] n/drive/mm/dmd/mech`.
### The VISIBLE limp — the gimp gait machines (reconstructed + bench-verified 2026-07-30) [T2]
Bench (madcat, novice, `BT_SELF_DAMAGE=60 BT_SELF_DAMAGE_ZONE=16 BT_SELF_DAMAGE_TICKS=2`,
`BT_GOTO` walk): right-leg crossing → alarm 4 → body enters 0x17/wgr FROM A LEFT STEP
(phase-correct) → both channels settle in 0x19/ggl and hold it 8k+ frames at the gimp cadence
cap (cycle 14.77 = the wgr entry stride, vs 18.5 walk / 22+ run) while raw demand stays 50 —
the slowdown IS the gait machine, no demand multiply. Two revive-bugs fixed en route: see
[[reconstruction-gotchas]] §24.
The binary's limp was hiding behind a **"jump-jet" misread**: the port had `FUN_004a5bf8` /
`FUN_004a71f4` reconstructed as `AdvanceBody/LegAnimationAirborne`, gated on
`(MovementMode()==3||4) && jumpCapable@0x580` and thought DEAD (mechs never jump). Truth
[T1, raw part_012.c]: **mech+0x40 there is the graphicAlarm level (3=left gimp, 4=right)**
and **+0x580 is `hasGimpClips`** — set by the conditional loader block that probes `wgl` and
loads clip slots 22-27 (`wgl wgr ggr ggl gsl gsr`, +0x624..0x638) plus four measurements:
`gimpLeft/RightSpeedMax`@0x53c/0x540 (the wg entry clips' final keyframe strides) and
`gimpLeft/RightStrideLength`@0x544/0x548 (MeasureClipStride over the gg cycles). The five
`jump*`-named members were renamed accordingly (mech.hpp; there is no jump clip set).
Machinery (all four reconstructed in mech2.cpp, gates in mech4.cpp):
- **Drivers** `AdvanceBodyAnimationGimp`@004a5bf8 / `AdvanceLegAnimationGimp`@004a71f4 —
selected per-frame when `(gimpLevel 3|4) && hasGimpClips`; clamp the demand (body:
`bodyTargetSpeed`; leg: the LIVE mapper `speedDemand`, written back) to the gimped side's
speed cap and advance the gg cycles at gimp cadence. **This clamp IS the authentic gimp
slowdown** — ground speed is clip travel, so the limp cadence bounds it; the earlier T3
`×0.5` stand-in in mechmppr is retired (`BT_GIMP_SPEED` remains as an override, default 1.0).
- **Finished-callbacks** `GimpBodyClipFinished`@004a6344 / `GimpLegClipFinished`@004a7970 —
branched to from the tops of the normal `Body/LegClipFinished`. **Phase-correct entry**:
left-gimp enters 0x16/wgl only from a RIGHT step (walk-R cases 5/6/0xe), right-gimp enters
0x17/wgr from a LEFT step (7/0xf) — the machine forces one extra normal step if mid-wrong-foot.
Cycles: left = 0x18 (ggr clip, stride @0x544), right = 0x19 (ggl, @0x548); exits through the gs
transitions 0x1a/0x1b when demand dies. No reverse entry exists while gimped.
**Turn-in-place while gimped** (field find, `95cf49d`): the binary's trn dispatcher
(`FUN_004a9b5c`, master perf) runs OUTSIDE the driver selection, so it arms the turn step for
gimped mechs too — the port relocated it into the NORMAL leg driver's Standing case, which
stops running when the gimp driver takes over ("rotating statue"). The arming is now mirrored
in `AdvanceLegAnimationGimp`. No gimp-turn clip exists — a limping mech step-turns with the
normal `trn` clip [T1: the RES limp set is only wg/gg/gs].
**Gimp audio — the "REVERSE DISABLED" voice IS REAL and now plays** (`1671b7d`; the earlier
"no voice exists" verdict here was WRONG — user/old-timer pushback found it). The authored mech
audio has **state watchers on `Entity.SimulationState == 3/4`** (the binary's one-cell mech+0x40
= the gimp level) that start a sequence playing notes 29, 16, **40** — two klaxon hits then
Warnings01 zone 8 (`Warnings01_z7.wav`, key 40-41) = the spoken "reverse disabled". It never
fired in the port because of the SAME cell split that hid the limp (graphicAlarm vs engine
simulationState, gotcha #23) — the audio watches the half the gimp system never wrote. Fixed:
mechdmg mirrors gimp 3/4 into `SetSimulationState` at the leg-half crossing (guarded vs
disabled/fall/dead), and `BT_GIMP_SAFE_BASE_READ` stops pre-gimp replication records from
stomping the cell (gimp is monotonic per life). Verified: `SetupPatch bank2 patch113 note=40`.
Layered under it: the `Entity.AnimationState` triggers on limp entries 22/23 + stops 26/27
(+ walk-stands 8/9) play **EngineShiftRev01** (downshift foley), velocity-gained — a separate
working layer (earlier mis-ID'd here as "the" limp audio). The earlier "watcher rebind"
hazard was a bench artifact (the harness gimped the mech before the audio object loaded —
impossible in play). ⚠ Open: an unidentified RAW writer (bypasses SetState; indicator-level
trap never fired while the value changed) resets the sim cell between damage events — under a
1 Hz bench harness it restarted the warning before the 1.8 s voice note; sporadic real-play
damage is unaffected. Needs a cdb write-watchpoint dig (candidates: a recon raw +0x2c-family
write or a struct copy spanning it).
### The gimp cell is REPLICATED STATE — peers limped for free in 1995 (#82, fixed 2026-07-29)
Field: "peers see a limping mech **skating**" (first-person limp + voice correct; bystanders saw a
normal walk sliding at limp speed; a stop/start did not clear it). Root cause chain, all [T1/T2]:
- The binary's one `mech+0x40` **is** `Simulation::simulationState`, which
`Simulation::Write/ReadUpdateRecord` puts in **every update record header** — so a peer's
replicant learned the gimp level on every packet and its self-simulated gait limped with no
extra plumbing. There is no gimp-specific replication anywhere in the binary because none is
needed.
- A replicant NEVER re-derives the level: zone damage reaches it as a DamageZone update record
(`Entity::ReadDamageUpdateRecord` → `DamageZone::ReadUpdateRecord` writes `damageLevel` straight
from the wire), which never runs `Mech__DamageZone::TakeDamage` — where the leg-threshold
evaluation and the `graphicAlarm` 3/4 write live. ⚠ And zone levels replicate only when the
**explosion table's** damage tier is crossed (`EXPTBL.cpp:512-530`
`CrossedDamageLevelThreshold`) — coarse and lagging (measured: peer at 0.428 while the master
was at 0.857). **Never infer damage state on a peer from replicated zone levels.**
- The port's own `Mech::PerformAndWatch` wrote `SetMovementMode(1)` **every frame** ("ground,
non-death, non-airborne"), which erased the gimp level from that cell once it was mirrored in
for the voice — so the wire carried 1 and peers walked. Found with the scoped `[simstomp]` trap
(`g_btGimpWatchMech` + module-relative return address → `symcrash.py`).
Fix: that per-frame write now writes the authoritative level (`gimped ? 3/4 : 1`) via the
alarm-only bridge `BTMechGimpAlarmLevel` (never the cell it feeds, so a respawn-cleared alarm
can't re-latch a stale gimp). Verified two-node (`scratchpad/night6/mp_skate.sh`): the observer's
replicant receives `sim=4` and its gait runs `23 → 25` (wgr entry → ggl limp cycle). This also
made the voice fire exactly once per onset instead of restarting on every damage event, and
re-enabled the authentic leg-destroyed→fall gate (`mechdmg` MovementMode 3||4 [T1 task #60]),
which had been dead while the cell was pinned at 1.
Open: the load-time per-clip callbacks `PTR_LAB_0050d738/744` on the wg clips (uncarved LABs,
inert `Recon` placeholders in the port — likely footstep/cycle events, transitions work without
them).

After the coupled body-channel peer landed (96a896a + turn-step f094d78 + cadence-mirror 23f1532), residual peer shakiness on accel/decel was RANDOM -- sometimes perfect, sometimes shaky. Root cause is the TEST RIG, proven with BT_RXJIT (record inter-arrival ms on the peer): two Debug btl4 nodes on ONE box contend for CPU, so Windows BATCHES their TCP delivery -- update records arrive in bursts (min ~0ms back-to-back, max 56-226ms gaps, burstiness max/avg 3-7x) instead of an even ~17ms. A peer dead-reckons across the long gaps then snaps when a record lands -> random shake. Pinning each node to a DISJOINT core set (ProcessorAffinity 0x00F / 0x3C0) restored even ~17ms delivery (burstiness ~1.0) and the shakiness vanished (user-confirmed). REAL pods are dedicated machines with no contention -- they never see this. DO NOT add an interpolation/jitter buffer or other un-authentic netcode to mask a single-box artifact.

## K/D authority + the scoreboard mirror — STRESS-PROVEN at 4 and 8 nodes (2026-08-11) [T2]
The scoring authority model (full map: [[combat-damage]] + `docs/KD_CHAIN_AUDIT_20260811.md`):
the VICTIM's master emits everything on its death edge (kill credit to the shooter via
replicant-Dispatch reroute, received penalty to itself, one VehicleDead); the killer's master
increments `killCount` when the rerouted credit lands; **killCount/deathTally never crossed the
1995 wire** — the port's #45 update-record extension mirrors them one-way owner→replicant
(read guarded replicant-only, mixed-version length guard, 2s heartbeat re-dirty). Bystander
nodes learn tallies ONLY through that mirror. Verified: `kd4_bench.sh` (bystander convergence +
no-mirror-exceeds-authority, receipt-derived per player) and `kd8_stress.sh` (8-node all-vs-all
melee, 26 deaths: 26/26/26/26 with zero duplicate-death swallows and zero `inst=R` deliveries).
The same-frame double-credit this closed (direct+splash lethal pair racing the deferred death
transition) is gotcha §25 — the death mode now flips synchronously inside the damage pass,
matching part_012.c:14761.

Established 2026-08-03 (#87 dig): the HOST binary lerps 13 material colour floats linearly

The card-side shading (how material colour selected/scaled the 256-row material ramps → final
texels) is i860 firmware, NOT in BTL4OPT.EXE — so the PERCEPTUAL damage-darkening curve of the
1995 pods cannot be recovered from this binary. Our port applies the host's linear factor at
draw (TFACTOR modulate, L4D3D). Field testimony ("a single missile leaves visible armor
damage") is arithmetically consistent with the linear curve — one 25-pt hit snaps a 68-90-pt
zone by 0.28-0.37 (measured live: amt=25 → rarm 0→0.3247) — but if the card's ramp mapping was

- **~~Myomer seek "SUPERCHARGE"~~ — ✅ RESOLVED same day: the players' testimony (Oracle:
seek-4 humanoid = 182 kph, overheat = freeze) prompted a re-audit that found the coupling in
the un-exported master-perf gap (@0x4a9cf2). The manual was right, 4.10 HAS supercharge, and
the port now implements it byte-grounded ([[subsystems]] WAVE 6 correction). LESSON: a
"no callers in the decomp" claim is only as good as the export coverage — sweep the raw image
for the operand pattern before declaring a data path dead ([[reconstruction-gotchas]]).
Original entry below for the record:** The 1995 manual (p20/p22 + stat sheets) says seek changes TOP SPEED (gear 4 =
"Supercharge", expert-only; Loki/Thor print Normal 143 / Super Charged 182 / Gimped 40 kph).

`Mover::localEnvironment` (MOVER.h:271) is declared and never populated anywhere in the port;
`GetEnvironment()->gravityConstant` is the named analog of the 1995 Mover's gravity POINTER at
`+0x250` (`FUN_00421e2c` does `vy -= **(+0x250)` per tick), which the myomer drive-heat
integrator uses for its `m·g·|vy|·dt` climb-work term. The bridge (`BTMechMyomerMotionSample`)
null-guards it, so climbing currently generates no myomer heat (flat maps: moot; cavern slopes:
a missing cost). EnvironmentZone resources (RES type 23) exist in BTL4.RES — wiring them (or at
least a constant-gravity Environment on mover birth) revives the term. Also relevant to any
future airborne/jump physics (`ApplyAirResistanceAndGravity` reads the same member).

player, +0x34 kill zone)? The function is not in the export; our #52 reconstruction predates
the fields. If it reads them, the likely consumer is a killed-by console post

status banner on the victim. The port SENDS them faithfully; raw-disasm the handler to close.
- **Collision-death tail fallthrough is inspection-tier [T3]:** the divert now falls to the death
tail (VehicleDead + blast) per @0x4a0375, but no live wall-death bench has run; field
wall-deaths exercise it nightly (watch for DEAD_NOTIFY on collision deaths).
- **The 1995 type-0 uninit-award bug** (documented in [[decomp-reference]] §BTPlayer table): the
shipped binary folds an uninitialized stack float into the shooter's score on every non-lethal

reaches the limit @0x1D8, at which point BOTH the timer and the flag are cleared. So the authentic
HUD has a timed **−100 m range offset** state that our targeting step (mech4.cpp — which does
reconstruct the 500 m/s slide correctly) never applies.
**Open:** what SETS @0x22C. Candidates not yet checked — a targeting-computer damage/jam effect, an

## Night-8 playtest intelligence (2026-07-31, build 4.11.674) [T2 player testimony]
**SENSOR PANEL — the model, from a player who ran the cabinets** (VGL Lynx; the last major system
without one; Gitea #105). Sensor damage degrades, in descending confidence: (1) the **HUD flickers**
— corroborated by period gameplay footage, and the distinctive tell to match; (2) **radar/map**
degraded or lost; (3) the **searchlight** (cf. #61, where Searchlight/ThermalSight ToggleLamp were
dead handlers); (4) the **hot box / thermal** suspected but unconfirmable — that feature is not
functional in our build. Next step is to find the sensor subsystem's damage consumers in the binary
and check which display paths it actually gates, rather than implementing from the description.
**COOLANT LEAK severity is a THREE-level display** (Oracle + Draco, Gitea #97): one/two/three
triangles, top level draining the reservoir fast, with an audible alarm. We only ever produce the
lowest. Our leak rate is a continuous scalar (`ownZone->damageLevel x heatLoad`, floor 0.0025,
ON hysteresis 0.003) — so either the banding into three display levels is missing, or the magnitude
never leaves the bottom band. Check whether severity is separately authored before deriving it.
**MYOMER heat calibration is CHASSIS-RELATIVE, not absolute** (Oracle, Gitea #96): a **Thor should
sustain seek 4 more or less indefinitely** on its heatsink count, while a light chicken-walker
overheats in well under a minute. This is the acceptance test for the drive-heat coefficient — the
spread should fall out of (drive heat / authored sink capacity) on its own, so a uniform "too hot"
across ALL chassis indicts the coefficient rather than the sinks.
**RAM damage: the binary's internal-only divert MATCHES what players see, and may be correct**
(Gitea #103). Oracle reported ram causing gyro + myomer damage and a myomer coolant leak but **no
armor damage**, with grinding inert — exactly `Mech::DistributeCollisionDamage`'s type-0 divert
(internals weighted Myomers/Gyro 0.35, HeatSinkBank 0.30, Torso 0.25; 0.5-pt free-tap floor).
Awaiting a player ruling on whether a hard ram ever damaged ARMOR in the original before treating
the absence as a defect.
**MP STABILITY datapoint** (RajelAran): a **5-player match with no egregious issues** — *"no
stability problems or massive lag spikes"*. Relevant to the carried cross-fire-stall and
silent-node-crash opens: neither reproduced at 5 players this session. Not evidence of a fix
(neither was addressed), but it bounds how often they occur.
## Post-re-export leads (2026-08-06, #60 closed — [[source-completeness]], `phases/phase-04-gap-census.md`)
- **`@0x4c0904` is the MASTER BTPlayer Performance — our `@0x4c083c` attribution needs a
re-check.** Newly lit by the re-export: it resolves the player's Team by name out of the
`Teams` registry (error string "Team ... does not exist"), calls `@0x4c083c` and the engine
`Player::PlayerSimulation` (`@0x42e100`), then at mission-end (state 4, past a threshold,
once) posts "Sending EndMission" to the console host, and on a timer posts the periodic
console SCORE update (`Round(currentScore)` — corroborating our hand-built scoreboard
heartbeat). btplayer.cpp currently documents `@0x4c083c` as PlayerSimulation; read both and
fix the attribution + fold in the team resolution (we have no Team-by-name resolve today).
- **`0x480a2a-0x487ca0` (~9 KB, l4splr|btmssn boundary) stayed dark THROUGH the re-export** —
the gap fill reached it with neither a call nor a data reference, which is itself a finding:
dead code, data misparsed as code, or reachable only through a jump table. The earlier
spot-check showed a real `enter 0x3c` function driven by a global-index dispatch table
(`[0x4fef88]` → table `0x501588`), so "dead code" is unlikely. Byte-scan for the table's

## Night-9 playtest intelligence (build 4.11.693, 2026-08-01)
**A MEMBER OF THE ORIGINAL TEAM IS NOW TESTING.** "Ronin" (log user `torak`,
machine TOWER_OF_TERROR) worked on the 1995 game and has played the pods
recently, including in Japan. He is a **primary source** — treat his comparisons
against the pods as high-value evidence, above reconstruction inference. Two
contributions already:
* **Per-chassis cockpit BOUNCE was deliberate** [T1, testimony]: "all of the
chassis have different cockpit 'bounce' — this was made so to help give the
'mechs some individuality". If our port applies one shared bounce curve, a
deliberate identity cue is missing. (Gitea #117; `jointshakey` is the likely
carrier — its pick sphere radius already differs per chassis.)
* **NARC may never have been implemented** [T3, recollection]: the loadout data
shipped but he does not recall the weapon being built. Squares with what we
see — an authored record that resolves with no distinct behaviour to
reconstruct. Mike L. could confirm. (Gitea #104.)
**AUDIO #32, CORRECTED DIAGNOSIS (2026-08-02): saturation during combat, NOT
retention** [T2 — census-measured]. An earlier version of this entry claimed the
pool "fills and never returns a source"; that was read off the FAILURE line, where
`free=0` is true by definition (a third instance of the counter-sampling trap).
The 30-second census in the same logs disproves it: `free` returns to ~227-230
between bursts and `reuses` climbs ~20/s all session — the pool cycles fine, and
release-on-stop exists and works (the engine's steal loop:
AudioSourceStop/SuspendMaintenance -> ReleaseChannels -> ReleaseSourceSet).
* The real regime: during firefights CONCURRENT demand exceeds the 240 cap and
the priority steal loop services each new sound by killing an old one,
thousands of times per combat session. Idle standing demand is only ~13.
* The raw `ACQUIRE FAILED` line count (6.8k-19k/log) is NOISE — the steal loop
retries after every failed attempt, so lines pile up per event and most
events still play via a steal. It is now rate-limited (1/30s) and the census
carries the true metrics: `steals=` and `drops=` (drops = the steal loop ran
dry and the sound NEVER played), plus a per-class drop histogram.
* The saturating requester is class 1005 = **Static3DPatchSource, 4 voices** —
world-placed effect sounds, i.e. EXPLOSIONS/impacts. Demand tracks the
number of SHOOTERS (9-mech one-shooter bench peaks at 130 with 0 fails; a
6-shooter field lobby pins 240). **#84's double detonation doubles exactly
this class on observer nodes** — fix #84 first, then re-read the field
census before touching the audio budget.
* `BT_AUDIO_SOURCES=<n>` now raises the POOL cap too, not just the AL context
budget (it previously did only the latter, making the experiment
impossible). If post-#84 logs still saturate, that is the field experiment
— with frame time measured, since more concurrent voices = more mixing CPU.
**Reading the missile impact line.** `[projectile] IMPACT damage=X ... burst=N`
prints X = **per missile**; the delivered total is `X * N`. A tester reading X
alone will report LRMs as doing ~3.3 damage when the salvo is landing up to 65.
Field-verified across 382 impacts: LRM20 3.25 x 5..20, LRM15 3.33 x 3..15,
LRM10 3.50 x 2..10 — burst ranges matching the binary's `Random(n) + n/4` roll
exactly.
**Weapon damage values are published** in the original manuals (Oracle: "that is
published ... Manuals had that info and it was accurate") — but NOT in the 4.0
manual we have archived (confirmed by Lynx). A later manual, or the wayback
capture of the original site's final build notes, would give hard per-weapon
numbers to test the authored data against. Worth chasing: it converts weapon
tuning from taste into arithmetic.
**Standard vs Expert heat is unsettled** and it contaminates every heat report:
Conn Man saw heat build-up in Standard while Rajel expected none there. See
Gitea #116 and `experience-levels.md`.
## Searchlight residuals (2026-08-05 — feature LIVE, [[rendering]] §SEARCHLIGHT)
- **Cone look pass pending**: spot.bgf hangs on the site joint with the site's rest transform;
the binary's per-case offset (local_2f0 at @004cef28 case 0xbd8) is believed to be the same
site offset [T3] — eyeball the size/aim on madcat/loki at night, then clear this.
- **BTL4VideoRenderer::LoadObject (@00498448) is a btstubs no-op** — the MechMarker beacon case
(MakeEntityRenderables 0xBBA) silently gets NULL and has never drawn. The searchlight went
around it (d3d_OBJECT::LoadObject direct). Reconstruct the wrapper or migrate the marker.
- **des_night-family pages have subtle fog deltas** (both sets near-black); arena/polar night
pages carry the dramatic 5↔40 near-plane swing. If testers report "searchlight does nothing"
on some maps, it's page authoring, not the mechanism.
## Replicant-side TakeDamage delivery -- mechanism uncharacterized (2026-08-11, from the #162 audit) [T4]
Replicant mech copies demonstrably EXECUTE `Mech::TakeDamageMessageHandler` (matchlog `DMG
inst=R` rows; the #150 bench observed replicant-side type-2 arms) -- yet every damage producer
uses `Entity::Dispatch`, and ENTITY.cpp:235-272 reroutes a replicant target's dispatch to the
wire WITHOUT local execution. Something delivers damage to the local replicant copy anyway
(wire-seam double-delivery? interest/watcher path? a port-side mirror?), and the 2026-07-25
corpus saw 0 of 18,818 DMG rows inst=R -- so the behavior APPEARED between then and 2026-08-09.
The #162 fix GATES every scoring/death consequence of it (reports + death tail are master-only),
so the scoreboard is safe regardless -- but the delivery mechanism itself is unmapped, and
replicant-side execution may have OTHER un-audited side effects (zone/subsystem state divergence
on peer copies beyond the intended visual application). To close: instrument the entry with the
delivery path (who posted it, from which socket/queue), find the first build where inst=R rows
appear, and decide whether the delivery is intended (visual-damage design) or a seam bug.
DATAPOINT (2026-08-11, the #162 retest wave): the kd4/kd8 benches audit this explicitly (I8)
and saw **0 inst=R DMG rows across three 4-node runs and one 8-node melee** (35 deaths total)
on build ~900 -- the behavior did not reproduce on the bench rig; whatever produced the
night-15 field rows needs field conditions (steam wire seam?) the LAN relay path lacks.

## ⭐ THE RGB SPLIT — how ONE VGA port drives THREE mono MFDs (decoded 2026-08-06) [T0 engine source + T1 authentic pod config]
The five monochrome MFDs are NOT five video outputs. Each VGA port's **R, G and B analog lines
are split to three separate monochrome monitors**, and the software puts a different MFD in each
colour channel of one shared palettized framebuffer. Mechanism, end to end:
1. **Every surface is a bit-plane + a CHANNEL.** `content/GAUGE/L4GAUGE.CFG` (the authentic 1996
pod config) configures each port as `configure(idx, port, rotation, bitMask, clut, COLOUR, palette)`:
| port | panel | mask | clut | channel |
|---|---|---|---|---|
| `Comm` | upper right | 0x8000 | clut2 | **red** |
| `Mfd2` (Engineering) | upper centre | 0x0400 | clut2 | **green** |
| `Heat` | upper left | 0x4000 | clut2 | **blue** |
| `Mfd1` | lower left | 0x0100 | clut1 | **red** |
| `Mfd3` | lower right | 0x1000 | clut1 | **green** |
| `sec` (+`overlay` 0x00C0) | secondary/radar | 0x003F | clut0 | **rgb** (full colour, rotation 270 — the physically ROTATED portrait CRT) |
`Eng1/2/3` are the engineering-page twins of Mfd1/2/3: same monitor, second bit-plane, switched
by `reconfigure(...)` giving one plane the channel and the other `blank`.
2. **The channel assignment is literally a palette write.** `L4GraphicsPort::BuildSecondaryColor`
(L4VB16.cpp) walks the palette entries owned by the port's bit group (`BitWrangler(byteMask,8)`)
and writes ONE component: `RedChannel -> triplet->Red`, `GreenChannel -> ->Green`,
`BlueChannel -> ->Blue`, `AllChannels -> the whole triplet`. `BlankColor` blanks the group
(`BlankPalette()`), which is how a page swap silences the plane it replaces. The
`*TransparentZero` variants skip colour 0 so zero reads as transparent for that group.
3. **So the DAC output carries three independent pictures**, one per analog line, and the splitter
hands each line to its own mono monitor. Three MFDs per VGA port; the pod's two MFD ports are
the **1280x480 "horizontally spanned" surface** (2 x 640x480 halves) the Displays section
describes — clut2 = the upper row (Comm/Mfd2/Heat), clut1 = the lower row (Mfd1/Mfd3, blue
spare). The radar rides its own port in real colour.
**Why this matters for the port [T2]:** our modern path renders each surface as its own
mono-tinted window on its own Windows display (see §MFD PANELS ON REAL HARDWARE), which is right
when every panel has its own output. **On splitter-wired glass it is wrong** — three monitors
would share one Windows display and each would show only its channel's share of a single tinted
image.
**`BT_POD_RGB=1` — the CHANNEL-COMPOSITE mode (built + field-verified 2026-08-06) [T2].** It
collapses the six panel windows into **three**: two VGA-port windows plus the radar. Each port
window composites its group's planes into ONE 640×480 BGRA image, each member ORed into its own
channel mask (`0x00FF0000` / `0x0000FF00` / `0x000000FF`), so the analog splitter downstream hands
each mono CRT exactly its picture. Grouping follows `L4GAUGE.CFG`: *VGA Port A* = Heat + Comm +
Mfd2, *VGA Port B* = Mfd1 + Mfd3; the radar keeps real colour on its own port.
`SVGA16::ExpandPlaneToBGRA` does the per-plane extraction, and `BT_POD_RGB` implies
`BT_POD_SURFACES`. Two companion gates came out of the bring-up: **`BT_POD_CHANMAP=<Port>=<colour>,…`**
remaps a surface's colour line when a cab's harness disagrees with the 1995 config (it did — see
§ALPHA-MR), and **`BT_POD_IDENT`** / **`BT_POD_CHANTEST`** paint identifying/cycling test patterns
so you can tell which physical CRT is which without trusting the desktop layout.
**SETTLED:** Nick's cart IS splitter-wired — its three 640×480 "displays" are VGA outputs, each
feeding a three-monitor splitter, and the composite is what lit the glass correctly.
## MFD PANELS ON REAL HARDWARE — the bring-up path (2026-08-06) [T2 local / T4 on-pod]
Nick's crash cart (pod hardware + Chrome Remote Desktop on a burner account) is the first chance
to drive the real panels. **The 1995 display path is NOT the way in.** That rig spanned the five
MFDs as ONE 1280×480 surface via **NVIDIA Horizontal Span, which every driver after XP dropped**;
`SVGA16::BuildWindows` also wants an exclusive-fullscreen D3D device per adapter, which is
fragile on modern drivers and over a remote session. Both are still in-tree and still the
authentic reference — they are just not the bring-up route.
**The route is the glass per-display windows** ([[glass-cockpit]]): one window per surface, which
maps 1:1 onto one physical panel per MFD, needs no special driver, and is already field-proven on
desktops. Two pieces were added for the cab:
- **`BT_POD_SURFACES=1` (pod surface mode, L4GLASSWIN)** — crops every window to its SURFACE
(MFDs exactly 640×480, radar 480×640 portrait), drops the on-screen RIO button banks (the cab's
buttons are PHYSICAL — drawing fake ones over a real panel is precisely wrong), goes frameless,
and does not create the Flight Controls pad at all (6 windows, not 7). Per-window equivalent:
append `,bare` to a line in `glass_layout.cfg` (mixed rigs).
- **Placement receipts** — every window logs `[glasswin] '<title>' surface=<port> at X,Y WxH
bare -> monitor \.\DISPLAYn (origin WxH, PRIMARY)`. On a cab nobody can see seven surfaces at
once, and over CRD you cannot see the panels at all: the log IS the confirmation that a picture
landed on the right glass.
### Boot-STABLE panel binding — `monitor:id:` (DEPLOYED + POD-VERIFIED 2026-08-10)
**Live on ALPHA-MR since 2026-08-10** — mapping eye-verified over livestream, then the master
`C:\bt411\glass_layout.cfg` flipped to the id form (old cfg saved as
`glass_layout.cfg.displaynbak`) and the relaunch bound all three windows to the SAME rects with
zero mismatch shouts [T2]. The shipped binding:
```
Secondary / Radar=monitor:id:Default_Monitor,bare # colour radar LCD, USB adapter
VGA Port A=monitor:id:UID224795,bare # RAR0005: Heat + Comm + Mfd2 CRTs
VGA Port B=monitor:id:UID200195,bare # RAR0005: Mfd1 + Mfd3 CRTs
```
⚠ **The radar LCD's USB display adapter presents NO EDID** — its only stable identity is the
`Default_Monitor` placeholder (`…#Default_Monitor#…&UID256#`). Unique today; a second EDID-less
panel would collide, and the per-boot `[glassid]` dump (BT_GLASS_IDS=1, now PERMANENT in
`podprofile.ini`) plus the mismatch shout are the diagnosis tools. The Dell (`DEL4025`) is the
PRIMARY main-view panel (BT_FIT owns it; not in the layout cfg) — the 08-08 note calling it a
"1908FP" service monitor mis-guessed its role.
**Windows renumbers displays.** Nick, after re-cabling + a reboot: *"the order changed … sometimes
they change when one gets turned off and back on, at least how windows SEEs them, even if the
visual desktop tool looks the same."* So the two original binding forms are both boot-fragile —
`monitor:2` is an enumeration index and `monitor:\.\DISPLAY4` is a GDI name Windows reassigns.
(Same trap next door in GameOS: its `-tmon` takes **DirectDraw device indices**, which are neither
Windows monitor numbers nor stable, and a NULL-device merge shifts every index down by one on top
— see Nick's `gos-displays.txt`.)
**The fix: bind to the panel's own hardware identity.** `EnumDisplayDevices` on a display's MONITOR
child returns a DeviceID embedding the **EDID manufacturer + product code** and the connector
instance — neither moves across a reboot or a power-cycle.
- **Discover:** run once on the pod with `BT_GLASS_IDS=1`. Every attached panel logs its
`stable-id` **and a ready-to-paste `cfg form`**:
```
[glassid] index=0 device=\\.\DISPLAY1 PRIMARY rect=0,0 1920x1080
stable-id = \\?\DISPLAY#AUO10ED#4&31323a6c&1&UID265988#{e6f07b5f-…}
cfg form = monitor:id:AUO10ED
```
The volatile identifiers print beside the stable one deliberately: run it twice across a
power-cycle and `index`/`device` move while `stable-id` does not — that IS the proof.
- **Bind:** `Heat MFD=monitor:id:AUO10ED,bare` in `glass_layout.cfg`.
- **Identical panels** (the pod's mono MFDs are likely one model, so EDID codes collide): use a
longer fragment from `stable-id` — the `UID…`/instance tail differs per connector, so
`monitor:id:UID265988` picks exactly one.
- **An `id:` that matches nothing WARNS and falls back** to computed placement:
`[glasswin] monitor id 'X' matched NO attached panel`. Silence there would put a picture on the
wrong glass and look exactly like the bug this form exists to prevent.
- **Nothing changes by default.** No env, no `id:` → identical behaviour; `monitor:<name|index>`
and raw `x,y` keep working. Playtester glass builds are untouched. [T2 verified on a 1-monitor
dev box — discovery, binding, centring and the mismatch warning; **T3 on the pod**, which was
offline: multi-panel disambiguation is unproven.]
**Runbook** (`tools/podprobe.ps1`, PowerShell, no install/admin — run it ON the pod PC):
1. Probe: GPUs, every monitor's virtual-desktop rect, EDID make/model (identifies the original
panels), serial ports (the RIO board), session type, and a PROPOSED `glass_layout.cfg` that
assigns the six surfaces to the non-primary monitors top-to-bottom/left-to-right, centred.
2. Drop the cfg in the game's working directory; run with `BT_GLASS_PANELS=1
BT_POD_SURFACES=1 BT_GLASS_LAYOUT=load` (`=save` to persist drags instead).
3. Read the receipts; re-assign titles to monitors in the cfg until each picture is on its panel.
Surface→panel roles: Heat MFD = upper left (coolant), Engineering = upper centre, Comm MFD =
upper right (hot box), Left/Right Weapons = lower left/right, Secondary/Radar = the secondary
screen (portrait). Main 3D view stays the game's own window on the main-view monitor.
**Known constraints / open on-pod questions:** whether the panels are attached to this PC at all
(the probe answers it); whether Windows offers a 640×480 mode on them (if not, the surface renders
at native size CENTRED, not scaled — a scale-to-fit option is the obvious follow-up); whether
Chrome Remote Desktop holds the CONSOLE session (it should — an RDP session would get a virtual
display and light nothing); and the RIO serial input, which is a separate task from the displays.
## ALPHA-MR — the verified cart config, FROZEN (2026-08-06) [T2, field-verified by eye]
The bring-up above landed: real pictures on real pod glass, then user-confirmed correct
("ok this is correct"). What that took, and where it now lives permanently.
**The rig.** Win10 IoT Enterprise LTSC on the cart; Intel HD630 + a "Trigger 6 External Graphics"
USB adapter. Four console displays: **DISPLAY3 800×600 PRIMARY at 0,0** (main view), plus
**DISPLAY4 @800,122**, **DISPLAY2 @1440,123**, **DISPLAY1 @2080,124** (each 640×480). Physical
cab: five mono MFD CRTs (two left stacked, two right stacked, one centre loose on the desk) plus
the colour radar LCD in the yellow-button frame.
**The mapping** (`glass_layout.cfg`, `monitor:<name>` binding — see [[glass-cockpit]]):
```
Secondary / Radar = monitor:DISPLAY4,bare # colour LCD, yellow-button frame
VGA Port A = monitor:DISPLAY2,bare # RGB triple: Heat + Comm + Mfd2
VGA Port B = monitor:DISPLAY1,bare # RGB triple: Mfd1 + Mfd3
```
Three windows, not six — under `BT_POD_RGB` each VGA-port window carries three MFDs on its three
colour planes (§THE RGB SPLIT). Desktop-coordinate order says NOTHING about physical cab position:
the first assignment, made by sorting monitors left-to-right, was wrong. Only eyes on the glass
settle it.
**Two deviations from the 1995 config, both real, both this cab's wiring:**
- **`BT_POD_CHANMAP=Comm=blue,Heat=red`** — kills/deaths and coolant loops came up on each
other's panel. `L4GAUGE.CFG` has Comm on red and Heat on blue; THIS cab's splitter harness
wires them the other way. The env override remaps a port's colour channel without touching the
authentic config file. [T2]
- **`BT_GAUGE_SEC_ROT=0`** — the radar here is a LANDSCAPE LCD, so the 640×480 source needs no
rotation. The 1995 pod's 270° rotation existed because its secondary CRT was mounted PORTRAIT;
it is a mounting fact, not a format fact. (En route: 180° looked plausible and was upside down.)
**Frozen in `content/environ.ini`**, not in a launcher — `scratchpad/pod/podprofile.ini` is the
block, `scratchpad/pod/mergeprofile.ps1` merges it idempotently between markers. environ.ini is
read before anything touches the environment ([[build-and-run]]), and the real environment still
WINS, so a .bat can override any of it for a one-off. The cart's `runpod.bat` now sets only
`BT_LOG`/`BT_GLASS_LOG` and the `-egg`; `runpod_env.bat` keeps the all-inline version as the
fallback. Two gates were added for this:
- **`BT_FIT=1`** — the env spelling of `-fit`, so the borderless main view survives however the
game is started (shortcut, scheduled task, autostart) instead of riding on one launcher's
command line. It fits `MONITOR_DEFAULTTOPRIMARY` = DISPLAY3, which is the main-view panel.
- **`L4PLASMA=NONE`** (also `OFF`/`0`) — no marquee at all. Needed because the GLASS profile
force-defaults `L4PLASMA=SCREEN`, so simply leaving it unset still puts a desktop plasma window
on the pod's glass. The boot banner reports `plasma off [L4PLASMA]` when it takes.
Verified on build 4.11.813 with the launcher carrying none of it: `[boot] environ.ini: 9
setting(s) applied`, `[cockpit] -fit: borderless 800x600`, `[glasswin] radar rotation 0 (none)`,
and all three surfaces on their intended `\\.\DISPLAYn`.
**Surviving a NEW BUILD, not just a reboot.** Both frozen files live INSIDE the versioned install
(`content\environ.ini`, `content\glass_layout.cfg`) and NEITHER ships in the zip — environ.ini is
generated on first run. So extracting a new build gives a cab that comes up wrong with no error
anywhere. The masters therefore live at the stable `C:\bt411\` (`podprofile.ini`,
`glass_layout.cfg`, `podkit.ps1`), and **`setup_pod.bat` pushes them into the newest `BT411_*`
folder** — run it once after each extract. `runpod.bat` resolves the newest install and applies
the kit itself before launching, so the remote path needs no hand-editing per build. Re-tuning the
cab means editing the MASTER at `C:\bt411\`, not the install's copy: the apply overwrites it, on
purpose, so there is one place to look when a panel moves. Repo copies: `scratchpad/pod/`.
**The tester launchers work on the cab unchanged (verified 2026-08-06) [T2].** `play_solo.bat`,
`join.bat`, `join_lan.bat`, `play_steam.bat` and `joyconfig.bat` set `BT_PLATFORM=glass`,
`BT_START_INSIDE=1`, `BT_DEV_GAUGES=1` plus their own mode flag — and **not one pod key** between
them. So each inherits the whole rig from environ.ini without knowing the pod exists. This is the
argument against a separate pod-only settings file: a second file would need every launcher to opt
in, which is the shape of the "competing keymaps" bug that made glass the default profile.
Observed: `play_solo.bat` on the cart logs `environ.ini: 7 setting(s) applied` — 7 not 9, because
the bat sets `BT_PLATFORM` and `BT_START_INSIDE` itself and the real environment wins.
Steam MP needs the **client installed and logged in** (AppID 480/Spacewar, so any account, no
purchase); installed on the cart 2026-08-06. ⚠ **#68: a failed JOIN/HOST exits the process
SILENTLY** — "Steam not running" and a real crash look identical to a player.
### The HARDWARE RIO is live on the cart (2026-08-06) [T2]
`L4CONTROLS=RIO:COM1,KEYBOARD` in the frozen profile — the real cockpit board instead of PadRIO.
The whole stock path above the seam (mapper, lamps, streamed `.CTL` mappings) runs unchanged; the
109-mapping `L4` control table installs exactly as it does on a desktop. **This is independent of
the platform profile** — the cab keeps the GLASS display stack (panels + RGB split) and only the
input device changes, which is what the glass/PadRIO seam was built for. Do NOT reach for
`BT_PLATFORM=pod` to get it.
- **Wiring:** `RIO:COMn` → `\\.\COMn` at **9600 8N1** (`L4SERIAL`); bare `RIO` defaults to COM1.
Reads are non-blocking (`ReadIntervalTimeout=MAXDWORD`, totals 0), so an absent or dead board
cannot hang the game — it just goes quiet.
- **RIO and PAD are MUTUALLY EXCLUSIVE** — both assign `rioPointer` in the `L4CONTROLS` parser, so
the last token wins. Selecting the hardware RIO turns the XInput pad OFF on that machine.
`KEYBOARD` is safe alongside: it only sets `flags.keyboardExists` and never touches
`primaryControlType`.
- **The board's own self-test is the diagnostic.** `RIO::RIO` runs it (`perform_tests = True` by
default) and writes `content\FAILURE.LOG` pages `RIOBoardErrors` / `RIODeadLamps` / `RIOErrors`,
deleting them first so the file is always current. On the cart, reproducibly: **4 missing boards**
(`Slot=3:Address=0`, `3:2`, `4:0`, `5:0`) and **16 dead lamps** (`AuxUpperRight1-8`,
`AuxUpperCenter1`, `TeslaRelay1/3`, `PanicButton`, `IcomAmpEnableRelay`, `IcomIncRelay`,
`FloorEntry`, `undefined_0x17`) — the crash cart is a PARTIAL cab, and those are the boards it
does not have. **A specific 4-of-many inventory is itself the proof the link is good**: a dead
serial line reports the whole address space missing, not four slots.
- **Input reaching the mech** was seen live as `[ctrlmap] push stick x=0.0595238 y=0` with nobody
at the cab — the physical stick sitting just outside the 5% deadband. NB when the stick is
centred this reads `x=0`, which is indistinguishable from no data: a centred-stick zero proves
nothing either way. ⚠ **Not yet checked by hand:** that stick/throttle/pedal travel and the
physical buttons drive the mech correctly, and whether the cab's pots match the `Ranger`
calibration baked into `RIO::RIO` (`JoystickX -96..96`, `JoystickY -97..108`, `Throttle 0..800`,
pedals `0..470`). A mismatch shows up as drift or short travel, not as an error.
- The boot banner names the resolved device — `GLASS (hardware RIO; plasma off [L4PLASMA])`. It
used to hardcode "PadRIO", which is a lie on a wired cab and exactly the line you read to check.
- ⚠ **THE COUPLING BUG this exposed (fixed 2026-08-06) [T2].** `BTGlassPanels_Create()` was called
ONLY from the end of the **PadRIO constructor** — the panels began life as the frames around the
on-screen RIO button banks, so "the buttons ride the device". Selecting the hardware RIO means
PadRIO is never constructed, so **every MFD window silently failed to appear**: the mission came
up on the main view with all the pod glass dark, and not one `[glasswin]` line in the log. The
MFD panels are a DISPLAY concern, so creation moved to `LBE4ControlsManager` after the
`L4CONTROLS` parse, where every device branch converges — plus a symmetric `BTGlassPanels_Destroy()`
in its destructor, because `~PadRIO` tore them down and `~RIO` knows nothing about them (windows
outliving the surfaces they blit would crash on the next mission cycle). Both calls are
idempotent (`Create` returns on `gWinCount != 0`), so the PadRIO path is unchanged and simply
arrives first.
**Working on the cart, remotely.** SSH over Tailscale lands in **session 0**, which has a dummy
"WinDisc" display and CANNOT see or enumerate session 1's windows — GUI work must go through
`schtasks /run /tn BT411Run` (task registered `/IT`), and window enumeration over SSH silently
returns nothing rather than failing. Kill `btl4.exe` BEFORE scp'ing a new exe or the file is
locked. The receipts in `podrun.log` are the remote eyes; a missing `DEBUG_STREAM` line in an
otherwise-logging run is real evidence that code path did not execute.
### The remote runbook — READ THIS BEFORE IMPROVISING (2026-08-08)
Every line below cost real time to rediscover on a live stream. Follow it in order.
**1. Connect.** `ssh bt411-pod` (alias in `~/.ssh/config`) → `bt411-pod.tail840fa4.ts.net`, user
`user`, key `~/.ssh/bt411_pod`.
⚠ **The key has existed since 2026-08-06 but ssh will NOT offer it without the config entry** — it
only tries default names (`id_rsa`/`id_ed25519`). Without it you get
`Permission denied (publickey,password,keyboard-interactive)`, which reads exactly like "auth was
never set up". It was. Also: the Tailscale **node** KeyExpiry (2027-02-02) is what keeps the cab on
the tailnet — it is **not** an SSH credential, and Tailscale SSH is **not** enabled on the pod (the
peer advertises no `sshHostKeys`), so port 22 is the pod's own Windows OpenSSH.
**2. Absolute paths for System32 tools.** Over this SSH+cmd session, bare `taskkill` / `setx`
return `The system cannot find the path specified.` and silently do nothing. Use
`C:\Windows\System32\taskkill.exe`. (`tasklist`, `schtasks`, `dir`, `copy` happen to resolve.)
**3. Deploy — the SAME procedure a tester uses.** No pod-special exe drops.
```
python tools/mkdist.py # -> dist/BT411_4.11.NNN.zip
scp dist/BT411_4.11.NNN.zip bt411-pod:C:/bt411/
ssh bt411-pod "powershell -NoProfile -Command \"Expand-Archive C:\bt411\BT411_4.11.NNN.zip -DestinationPath C:\bt411 -Force\""
ssh bt411-pod "powershell -NoProfile -ExecutionPolicy Bypass -File C:\bt411\podkit.ps1 -Content C:\bt411\BT411_4.11.NNN\content"
```
`runpod.bat` auto-resolves the **newest** `BT411_*` by date, so nothing else needs pointing.
Local config is **never clobbered**: `mkdist.py` packs git-TRACKED content only, and
`bindings.txt`/`environ.ini`/`glass_layout.cfg` are all gitignored. `podkit.ps1` pushes the frozen
rig masters (`podprofile.ini`, `glass_layout.cfg`, `PODTEST.EGG`) from `C:\bt411\` into the install.
⚠ **`PODTEST.EGG` is not in the repo** — only podkit carries it. If podkit fails, the launcher runs
and *nothing appears*, with no error.
**4. Launch.** `schtasks /run /tn BT411Run` → runs `C:\bt411\runpod.bat` as `user`,
LogonType=Interactive, so it lands in **session 1** and is visible on the panels. Log:
`<install>\content\podrun.log`.
**5. ⚠ THE PODKIT INFINITE LOOP — the trap that ate an evening.** `podkit.ps1` line 30 was
```powershell
while ($keep.Count -gt 0 -and $keep[-1].Trim() -eq '') { $keep = $keep[0..($keep.Count-2)] }
```
When `$keep` trims to ONE blank line, `$keep.Count-2` is `-1` and PowerShell's `$keep[0..-1]`
returns **two** elements instead of shrinking — infinite loop, RSS climbing past 60 MB. It fires
whenever everything outside `environ.ini`'s marker block is blank, i.e. **any `environ.ini` that was
already kitted** — exactly what you get carrying it forward from the previous install. Patched to
`-gt 1` on the pod 2026-08-08 (`podkit.ps1.bak` is the original); **this fix is NOT in any repo**,
so a restored/replaced podkit brings the bug back.
*Signature:* a **blank cmd console** on the pod, task stuck `Status: Running`, **no `btl4.exe`, no
`podrun.log`**. *The cascade:* each hung run holds `environ.ini`, so every later attempt blocks too —
and over SSH your client times out while the REMOTE powershell keeps running, so "it returned
instantly and did nothing" actually means "it is still hung". Recover with
`taskkill /F /PID <pid>` (absolute path) on the session-1 `cmd`+`powershell` pair, then
`schtasks /end /tn BT411Run` before re-running — a task already Running refuses `/run` with
`2147946720` (`0x800710E0`, "operator refused the request").
**6. Panel identity (measured 2026-08-08, over SSH — WMI is session-independent so this works
without a GUI):** `DISPLAY\RAR0005\…UID224795`, `DISPLAY\DEL4025\…UID249395` (DELL 1908FP),
`DISPLAY\RAR0005\…UID200195`. **The two RAR panels share one EDID code and have blank serials**, so
`monitor:id:RAR0005` is ambiguous — they must be bound by the per-connector form
(`monitor:id:UID224795` / `monitor:id:UID200195`). **RESOLVED 2026-08-10:** the full map is
UID224795 = VGA Port A (Heat+Comm+Mfd2), UID200195 = VGA Port B (Mfd1+Mfd3), `Default_Monitor`
(EDID-less USB adapter, UID256) = the colour radar LCD, DEL4025 = the PRIMARY main-view panel
(not a service monitor). The master cfg now ships the id form (see the binding section above);
`glass_layout.cfg.displaynbak` preserves the old DISPLAYn cfg.
**7. ⚠ cmd redirect trap when scripting over SSH:** `echo VAR=1>> file` appends `VAR=` — cmd
parses the digit-adjacent `1>>` as a stream-handle redirect and eats the value (and MSVC putenv
treats an EMPTY value as UNSET, so the flag silently never arms). Space it (`echo VAR=1 >>file`,
trailing-space payload) or use PowerShell `Add-Content`. Bit us arming BT_GLASS_IDS 2026-08-10.
**8. Tester-procedure deploy VERIFIED end-to-end (2026-08-10, build 876):** scp zip →
`Expand-Archive` → podkit → `schtasks /run` came up clean on the first try — rig config survived,
newest-install auto-resolve worked, no hand-edits. The cab genuinely upgrades like a tester box.
**9a. ⚠ THE RIO's "COM1" IS A USB-SERIAL ADAPTER — the axis-dropout / frozen-boot fault
(2026-08-10, minidump-proven) [T1].** `\Device\VCP0` = an FTDI adapter (FTE7PGA5A); COM2 is a
second FTDI (A995JTOYA); **two ghost Prolific PL2303 entries also claim "COM1"** from earlier
plug-ins (clean them in Device Manager). When the adapter's **USB side** drops mid-operation:
brief drop = analog polls go mute (the field "encoder dropouts", revived by hand-jostle /
re-enumeration — NOT by button protocol); drop with a write in flight = the 1995 code's
**unbounded `GetOverlappedResult` wait in `PCSerialPacket::SendPacket` parked the whole game at
0 CPU forever** (three boots on 2026-08-10; stack: NtWaitForSingleObject ← GetOverlappedResult ←
SendPacket ← RIO ctor). **Hardened in 4.11.881**: 500 ms bounded write + CancelIo + 3 s sick
window (fast-drop, game keeps frame rate, keyboard fallback lives); `txTO=` in the `[rio]` health
line counts the events — proven the same evening (`txTO=1 rRetry=4` on a boot that SURVIVED).
USB **selective suspend disabled** system-wide on the cab the same day (powercfg) — prime suspect
for the random-period idle dropouts. Hardware to-do: FTDI adapter into a REAR motherboard USB
port, reseat its USB end. ⚠ A first "print-deadlock" diagnosis of the boot wedge was WRONG
(confounded A/B) and is retracted — the dump is the authority.
**Day-end state (2026-08-10 evening) + the pick-up plan.** The 881 soak measured the fault
precisely: the board answers for **~13 s after each fresh game start** (254 replies at 20 Hz),
then goes MUTE on analog for minutes while host→board writes keep completing (`req=3846 rep=254
age=240s`, txTO frozen at 1, abandon=0). Direct hand-poll (`tools/probe_rio.ps1`, also at
`C:\bt411\probe_rio.ps1` — raw COM1 CHECK/VERSION/ANALOG with correct [cmd][sum&0x7F] framing,
DTR/RTS raised): **zero bytes**. USB re-enumeration of BOTH FTDI converters + immediate re-poll:
**still zero** — which argues AGAINST the adapter (a wedged adapter RX clears on re-enum) and AT
the board. ⚠ [T4 hypothesis for tomorrow]: 13 s ≈ when the mission render load lights up — a
**power rail sagging under the cab's full load** would also explain the original mid-combat
dropouts (explosion/load transients) and the button "revival" (load dips + harness jostle).
Tomorrow, with hands: (1) loopback plug on the FTDI (TX→RX jumper, probe echoes = adapter fully
exonerated); (2) 5 V/12 V at the RIO board while a mission loads (the 13 s correlation is the
test); (3) swap in one of the spare Prolific adapters as cheap elimination; (4) rear-mobo USB
port + ghost-COM cleanup regardless. ⚠ My STALL/RECOVER edge detector in 881 keys on
request-age, which the 50 ms poll keeps resetting — it never fires; the `age=` field carries the
real signal (fix the keying to reply-age at the next build).
**Remote minidump procedure (worked over SSH, no tools install):** 32-bit dump of the wedged pid
via `C:\Windows\SysWOW64\rundll32.exe C:\Windows\SysWOW64\comsvcs.dll, MiniDump <pid>
C:\bt411\w.dmp full` → scp home → local x86 cdb (`where.exe cdb` resolves the bt411-tools copy)
with `-y C:\git\bt411\dist` (the archived per-build PDBs) → `~*k`. A 64-bit comsvcs dump of the
WOW64 process shows only 64-bit frames — use the SysWOW64 pair.
**9. ⚠ `schtasks /end` ORPHANS the game — the dead-RIO trap (2026-08-10):** `/end` kills the
batch, but `runpod.bat` `start ""`s the exe DETACHED, so the old btl4.exe survives, keeps COM1
open, and the NEXT launch boots with a dead cockpit board: `InitSerialPort() failed
[GetLastError() = 5]` (access denied) → `RIO initialization failed!` → buttons dead while the
banner still says "hardware RIO" (the banner is the PROFILE, not the init result). Diagnosis:
`tasklist /FI "IMAGENAME eq btl4.exe"` showing ≥2 instances. FIXED at the root the same day:
`runpod.bat` now `taskkill /F /IM btl4.exe`s FIRST (original saved as `runpod.bat.bak`), making
the BT411Run task an idempotent restart — but any hand-rolled launcher on a future cab needs the
same line, and a mid-mission `/run` now RESTARTS the game rather than failing quietly.

gap (@0x4a9cf2: `speedDemand *= max myomer speedEffect`, turn-freeze at dead drive; see
[[subsystems]] WAVE 6 correction). The manual is ACCURATE for 4.10; Oracle's pod memory
(seek-4 humanoid = 182 kph = the printed figure) confirmed it and prompted the re-audit.
The paragraph below is retained as the record of the error (its BINARY facts — the two
exported AvailableOutput callers, the single attr ref — were correct but incomplete:
export-gap functions are invisible to decomp text sweeps).
~~ORIGINAL (WRONG) VERDICT:~~
Manual p20/p22: seek "translates to a lower or higher top speed", gear 4 is named
**Supercharge** (screenshot caption "Seek Level Is Set to Supercharge"), expert-only ("in
standard simulation mode, you are not able to supercharge"), and "overheated myomers can
reduce your 'Mech's speed to zero". Stat sheets print THREE top speeds (Loki/Thor: Normal
143 / **Super Charged 182** / **Gimped 40** kph). The 4.10 BINARY dropped the runtime
coupling entirely: the mapper demand @004afd10 has no myomer/seek term, `AvailableOutput`
has exactly two callers (assembly cap + graph), and the SpeedEffect attribute string has one
reference (its own table row). Even the printed ratio disagrees with 4.10's authored gears
(182/143 = 1.27 vs 0.9999/0.7 = 1.43) — the gear table and the assembly cap are vestiges.
In 4.10 the seek dial's live effects are heat (ratio² ≥ 1), the generator brown-out
threshold (whose real stake is TORSO TWIST — see [[subsystems]] WAVE 6), and the ENG graph.
"Top Speed Gimped 40" also confirms the limp-gait speed cap as an authored spec. The port
follows the BINARY (house rule); resurrecting manual-4.0 supercharge would be an opt-in
deviation for the operator to decide.

## 20. Export-gap blindness — absence in the EXPORT is not absence in the BINARY (4 incidents)
The Ghidra export (`reference/decomp/`) has coverage gaps (#60), and BTL4.RES content never
appears in it at all — so "no readers", "no caller", "no such clip/asset", and "unreconstructed"
claims made by grepping the export or the port ALONE are structurally unsound. This class has
produced four wrong conclusions, two of them [T1]-tagged at the time:
1. **2026-07-25 searchlight "1995 latent bug"** — compared Searchlight's Performance against
THERMALSIGHT's handler (wrong class) and invented a missing bridge; retracted (#61).
2. **2026-07-2x `DuckState` "has no CODE consumer, authentic [T1]" + "no SQUAT clip survives"** —
the consumer was the un-exported master-perf posture block (@0x4aa011), and the clips lived in
BTL4.RES (`squ/sqd/squi/sqdi` × 8 chassis); the search covered decomp strings + loose files,
never the RES TOC. Disproven by the CROUCH reconstruction (2026-08-06).
3. **2026-07-31 morning: the myomer drive-scale DELETION** ("the binary has NO dynamic
myomer→speed coupling") — the consumer was un-exported; restored same day by raw capstone.
4. **2026-08-05 "the myomer factor FEEDER (@004b8be3) is unreconstructed"** — it had been fully
reconstructed since 07-31 under NAMED members (`speedEffect`, `AvailableOutput`); the grep
searched raw offsets. Cost: a duplicate multiply + a dead crouch gate until 08-06.
**The rule — before claiming "X does not exist / is not reconstructed":**
- byte-scan `content/BTL4OPT.EXE` for the offset/immediate (disp32 patterns), never just the export;
- grep the port for NAMED members (check the .hpp for the offset's name) — offsets rot after promotion;
- for content claims, walk the **BTL4.RES TOC** (`tools/resscan.py` pattern), not the loose tree;
- check `reference/BT410_SOURCE_MANIFEST.md` + `game/reconstructed/CLASSMAP.md`;
- and tag the claim's tier by the WEAKEST source consulted — an export-only sweep caps at [T4].
The #60 gap census + RE-EXPORT is the systemic fix, and BOTH shipped 2026-08-06: the export
now covers 93.5% of .text (dark code 90 KB → 41 KB) and `reference/decomp/GAP_CENSUS.md` maps
what is still dark. **So the rule is cheap now: look the address up in GAP_CENSUS.md first.**
If it is NOT in a dark region, the export is authoritative and "absent" means absent. If it IS,
byte-scan before claiming anything. (Toolchain + method: `phases/phase-04-gap-census.md`.)

## 23. `AlarmIndicator` is a DIFFERENT TYPE per header family — Mech's layout diverges across TUs (2026-07-30)
Found chasing #78: `mechdmg.cpp` wrote `mech->graphicAlarm.SetLevel(4)` and read 4 back;
`mechmppr.cpp` read **0** from the *same object, same expression, same frame family*. Root cause:
```cpp
mech.hpp:67 typedef ReconAlarm AlarmIndicator; // 4 bytes {unsigned level}
heat.hpp:52 typedef GaugeAlarm AlarmIndicator; // 0x54 bytes (the real binary alarm)
```
`Mech::graphicAlarm` is declared `AlarmIndicator` — so a TU's include ORDER decides which type
that member is, and **every Mech member after it shifts by 0x50 between the two families**. A
write through one family's layout is invisible to a read through the other. This is the shadow
trap operating at the TYPEDEF level, where no compiler error can catch it (each TU only ever sees
one definition).
**Rule:** any cross-TU read/write of a Mech member declared past `graphicAlarm` must go through a
bridge compiled in a KNOWN TU (`BTMechGimpLevel` in mechdmg.cpp is the pattern) until the typedef
split is audited and unified. The audit itself — which TUs resolve `AlarmIndicator` to which
type, and which member traffic crosses families — is an open work item; the same split-brain also
explains why `MovementMode()` (the engine `simulationState`) and the KB's "movementMode IS the
graphicAlarm level" (task #1) never actually met in the port: they are two different cells, both

The gimp gait drivers (`AdvanceBody/LegAnimationGimp`, ex-"Airborne") sat reconstructed-but-dead
for weeks while their gate read the wrong cell (gotcha #23's split-brain). The moment the gate
was fixed and they ran for the first time, they reproduced — within seconds of engagement — TWO
bugs the LIVE drivers had each been cured of long before:
1. **the raw `*(this->controlSource)` mapper read** (`controlSource@0x128` is never wired in the
port; the live drivers were converted to `MappingMapper()` — the dead one crashed at
`AdvanceLegAnimationGimp+0x16`, null deref, first live engagement);
2. **the missing alarm→member state re-sync** (`bodyAnimationState = bodyStateAlarm.GetLevel()`;
the binary has ONE cell, the recon has two — the ground drivers re-sync at :831/:1181; the
dead driver didn't, so the state member froze at its pre-gimp value and the machine pinned in
one run state for 8000+ frames).
**Rule:** before wiring a long-dead reconstructed function into a live path, diff it against its
LIVE sibling for the port-glue idioms (mapper access via `MappingMapper()`, alarm→member
re-syncs, null guards, `BTEnvOn` gates). The binary-faithful parts transplant cleanly; it is the
RECON-side glue that will be missing, because every glue fix landed only where code was running.
## 25. A SPLIT cell breaks REPLICATION silently — and per-frame writers erase the half you added (2026-07-29)
The gimp-level saga's second act (#82). When the port carries one binary cell as TWO members, the
damage isn't only cross-TU reads (gotcha #23) — it is **which half rides the wire**:
- `Simulation::simulationState` is replicated in EVERY update record header
(`Simulation::Write/ReadUpdateRecord`). Any binary state living in `mech+0x40` therefore
replicated for free. The port's parallel member (`graphicAlarm`) replicates **nowhere**, so every
behavior a peer derives from it silently becomes master-only — visible as "peers see something
different" bugs (here: a limping mech that skated on every other pod).
- Worse, the engine cell usually already has a **per-frame writer** with a narrower idea of what it
means (`Mech::PerformAndWatch`: `SetMovementMode(1)` = "ground, non-death, non-airborne"). The
moment you mirror extra semantics into it, that writer erases them 60×/second — and the symptom
is not a stuck value but a 1→N→1 oscillation whose edges retrigger anything watching (the
warning-voice sequence restarted on every damage tick and never reached its spoken note).
**Rules:**
1. Before mirroring into an engine cell, `grep` for its per-frame writers and teach them the new
value (write `gimped ? 3/4 : 1`, not a blind `1`).
2. Read the authority, never the cell you feed — an alarm-only bridge (`BTMechGimpAlarmLevel`)
keeps a respawn-cleared alarm from re-latching stale state out of the cell.
3. Don't "fix" a stomp by patching incoming records: on a replicant the master's records ARE the
authority, and pinning a local value against them makes state stick forever (that draft would
have kept peers limping through a respawn). Find the writer instead.
**Tool:** scope the trap. `StateIndicator`/`Simulation` state traps drown in subsystem churn —
filter to one watched object (`g_btGimpWatchMech`) and print the caller module-relative
(`btl4+0x…`) so `tools/symcrash.py` names it. That turned a two-hour guess into one line.
## §21 — Export-gap blindness: "no callers in the decomp" is NOT "no callers in the binary"
**(2026-07-31, the myomer seek retraction — the costliest wrong verdict to date.)** The Ghidra
export has GAPS (gitea #60): whole functions absent from `reference/decomp/all/*.c` — the
master-perf region 0x4a9770-0x4ab188, the 0x4a03xx crit caller, @004b838c, and others. A text
sweep of the decomp for callers/readers of a symbol **cannot see a consumer that lives in a
gap**. The myomer `speedEffect@0x31C` demand feed was declared dead on exactly such a sweep
("two AvailableOutput callers, one attribute reference, no raw readers") and an already-correct
port mechanism was deleted on that basis — while the real consumer sat un-exported at
@0x4a9cf2 (`speedDemand *= max myomer speedEffect` + the dead-drive turn freeze). Field
testimony (Oracle: pod seek-4 = 182 kph, the manual's printed figure) forced the re-audit.
**RULE: before declaring a data path dead, sweep the RAW IMAGE for the operand pattern** —
capstone over the CODE section for the addressing form (e.g. FPU reads of `[reg+0x31C]`, SIB
`[reg+reg*4+0x330]`). Minutes of scanning; it found in one pass what three decomp sweeps
missed. Corollary: when the decomp and a PRIMARY SOURCE (the manual, a pod veteran) disagree,
treat the disagreement as a hole in YOUR evidence first, not in theirs.
## §22 — The SPLIT CELL: one binary offset, two port members (only one gets written)
**(2026-07-31, gitea #86 "destroyed weapons keep firing".)** The binary's weapon fire gates test
`subsystem+0x40`. In the 1995 layout that offset is *inside* the embedded status alarm
(`statusAlarm@0x2C` + the indicator's level at `+0x14` = `0x40`) — **one cell**, written by
`ForceCriticalFailure` when a zone's crit-cascade kills the subsystem. The port models the same
address as TWO independent members: `AlarmIndicator statusAlarm` **and** a plain
`int simulationState@0x40`. Every destruction path writes the ALARM (so the MFD correctly draws
its X, the paper doll correctly greys the mount) while the fire gates read the plain int — which
nothing ever writes. Result: a weapon on a blown-off arm shows destroyed on every panel and
keeps firing and scoring, on the shooter's screen and on peers' (all three night-7 testers).
**Detection smell:** a diagnostic that prints the gate's own inputs and shows a state flag
reading 0 while the UI bound to "the same" state shows destroyed. (`[ammo] NoAmmo (gate1):
destroyed=0` on a mech with an X'd-out launcher was the tell — it sat in the logs for weeks.)
**Rule:** when a binary offset falls inside an embedded object in OUR layout, do not mirror it as
a sibling scalar — read it through the object that owns it, or (if a duplicate member already
exists) make every gate read BOTH and every writer write BOTH. Sibling of gotcha #1 (shadowed
base field): same failure shape — two cells where the binary has one, and the readers pick the
dead one.
## §23 — Scaling `D3DMATERIAL9` does NOTHING for BGF geometry (the vertex-colour diffuse source)
**(2026-07-31, gitea #87 "mech armour panels don't darken".)** The 1995 armour damage darkens a
mech by scaling its MATERIALS' colour terms (`dpl_SetMaterialAmbient/Emissive/Diffuse/Specular`).
The obvious port translation — scale the draw op's `D3DMATERIAL9` before `SetMaterial` — renders
**byte-identically**: measured **0 changed pixels** at a full 0.1x scale.
**Why:** D3D9 defaults `D3DRS_DIFFUSEMATERIALSOURCE` to **`D3DMCS_COLOR1`** (and `D3DRS_COLORVERTEX`
to TRUE), so when a vertex carries a diffuse colour the material's Diffuse is never consulted.
Every BGF vertex carries a baked colour (that IS the 1995 shading model — no-normal geometry is
unlit and coloured by vertex/ramp), so for essentially all world geometry `SetMaterial` is inert
for colour. The material only matters for lit, normal-bearing meshes.
**Fix pattern:** modulate the FINAL fragment instead — `D3DRS_TEXTUREFACTOR` + a
`MODULATE(CURRENT, TFACTOR)` on texture **stage 1** (unused in `d3d_OBJECT::Draw`), restored to
`D3DTOP_DISABLE` after the op. That darkens the result whatever the diffuse source was, and
equally covers the ramp-baked-texture path and pure-emissive batches.
**Detection smell:** a colour change that logs perfectly at the source and produces zero visible
difference. Diff two runs pixel-wise against a control region before believing a colour path
works — "the log says 0.1x" is not evidence that anything reached the screen.
## §24 — A verified fact, OVER-GENERALISED, becomes a wrong design premise
**(2026-08-01, gitea #95 "missiles land 3 points instead of 50".)** The KB carried this, tagged
**[T1]**: *"`DamageZone::TakeDamage` is `damageLevel += amount*scale` and IGNORES `burstCount` — so
`burstCount` is cosmetic for zone damage."* The first clause is **true and byte-verified**
(`@0041e4e0`). The second is an **inference** that was written down beside it, inherited the [T1]
tag, and then justified a design decision (task #62's salvo-lead model) that silently divided every
missile salvo by its missile count for months.
**What was actually true:** `TakeDamage` ignores `burstCount`; the **CALLER**
(`Mech::TakeDamageMessageHandler` @0x4a0423-0x4a04d8) honours it by calling `TakeDamage` that many
times, re-rolling the zone per burst. The consumer was one stack frame up — the same blind spot
shape as §21 (export-gap blindness), but with the evidence *present* and simply not followed
outward.
**Detection smell:** a "cosmetic"/"unused"/"vestigial" claim about a field that other code still
computes carefully. Here the binary randomises `burstCount` at impact (`Random(n) + n/4`) and the
splash code derives it from a distance falloff — nobody spends instructions rolling a decorative
value. **If a field is called dead, ask who still writes it, and why.**
**Rule:** tag the VERIFIED clause, not the paragraph. An inference sitting next to a [T1] fact is
still [T4] — split them, or the next reader (including you) will build on the guess.
## 26. The SILENT-STUB walk: empty iterators make a faithful-looking mechanism a no-op (#110)
`RecurseSegmentTable` was "reconstructed" against local shim types whose
iterators unconditionally returned NULL (`SegmentIterator::Next() { return 0; }`,
`SegTableX::operator[] { return 0; }`). Every line of the walk mirrored the
binary -- and none of it did anything: the destruction cascade fired, logged,
"descended", and touched no other zone. The symptom (gun pods surviving their
blown-off arms) was field-reported for weeks while the code READ correct.
The trap: a stub that returns EMPTY (rather than asserting/crashing) converts a
reconstruction into silent fiction, and the no-stand-ins rule cannot catch it by
reading the call site -- the stand-in hides in the TYPES. The engine already had
the real structures (`EntitySegment::damageZoneTable` / `childIndexTable`, T0,
byte-matching the decomp's seg+0xD0/+0xE8) -- the stub was never necessary.
Rules: (a) when a reconstructed mechanism runs but nothing downstream changes,
grep its helper types for `return 0` bodies FIRST; (b) a bring-up shim must
either Fail() loudly or log its own emptiness, never silently iterate nothing;
(c) before shimming an engine-side structure, check whether the engine already
has it -- the offsets in the decomp comment ARE the lookup key.
## 27. Drawing where the design says DON'T: under-surface buttons, shared planes, and inherited D3D state (#118, 2026-08-03)
Three MFD-corruption incidents in one evening, all mine, all the same class:
adding a DRAW to a compositor whose layout invariants I had not read.
1. **The eject-wipe gauge** (BitMapInverseWipeScalar) drew into a weapon's ENG
graphics port -- but the Eng1-3 planes SHARE composite dest cells with the
weapon pages (`ckSlotOf` in L4VB16), so its mis-geometry scribbled striped
garbage OVER the weapon MFDs whenever an eject cycle redrew it (= at
overheat-jam onset, which the operator correctly correlated with "when the
coolant warning starts").
2. **The "flash overlay"** re-drew flashing buttons' full faces ON TOP of the
surfaces. But the side buttons are BIG rects deliberately tucked UNDER the
displays -- the protruding edge IS the lamp (the pod's backlit keys sat
beside the CRT; there is no in-display face). A full-face redraw is wrong
BY DESIGN: it covers gauge imagery with button faces.
3. **The same overlay, drawn after `DrawDevSurface`, inherited its bound
texture** -- an un-reset `CkFill` renders a TEXTURED quad sampling the
gauge atlas: green diagonal-striped rectangles. (With the state reset the
bug became honest: solid flashing faces covering the MFD -- which is how
the operator's "the panel buttons took over the MFD" report finally
identified the author.)
Rules: (a) before ADDING a draw to an existing render pass, read the pass's
layering comments -- "UNDER the surfaces", "masks the part inside", "shares
its sibling's dest cell" are INVARIANTS, not descriptions; (b) any D3D draw
inserted after another subsystem's draws must re-assert its own texture/color
state (CkColorState-equivalent) -- the previous draw's bindings are live;
(c) when a visual corruption tracks an EVENT ("starts with the coolant
warning"), list what STARTS DRAWING at that event -- alarm-driven redraws,
state-change repaints -- before suspecting the event's logic; (d) the
operator's screenshot is worth ten theories: the red-faces capture identified
in one frame what three log-side hypotheses missed.
## 28. HAND-COMPOSING an engine-derived transform reads a STALE CACHE — and it only bites REPLICANTS (#141, 2026-08-08)
`EntitySegment::GetSegmentToEntity()` (`SEGMENT.cpp:262`) **recomputes only when
`segmentModified` is already set** — otherwise it hands back the cached matrix,
and if the segment has no parent it can never recompute at all. The thing that
sets that flag after a joint moves is `JointedMover::GetSegmentToWorld`
(`JMOVER.cpp:136-146`): it tests `AreJointsModified()` and, when set, walks the
whole segment table marking every entry dirty, then clears the joint flag.
The binary agrees exactly. `MechWeapon::GetMuzzlePoint @004b9948` ends in
`FUN_00424da8(owner, segment, out)`, which IS `GetSegmentToWorld`
instruction-for-instruction (`GetJointSubsystem` → `if (AreJointsModified())` →
mark all → `ModifyJoints(False)` → `× localToWorld`). **So in the 1995 image
every muzzle query performs the joints→segments refresh.** [T1]
Four port sites had replaced that with `mw.Multiply(seg->GetSegmentToEntity(),
mech->localToWorld)` — including one commented "the faithful FUN_004b9948".
They skip the refresh and read whatever cache is present.
**Why it hid for a year:** the local mech is refreshed every frame anyway — the
renderer and cockpit camera call `GetSegmentToWorld` on it, *after* its torso
pushes the joint. So master-side output is correct and solo testing is clean.
A **replicant** gets no such pass: its cache stays at the BIND POSE. Measured on
a 2-node bench, peer missiles left along the LEG facing with `segYaw == bodyYaw`
EXACTLY (`twistDelta` 0.0000 over 165 salvos) while that same peer's copy torso
was demonstrably writing its joint (`PushTwist COPY twist=-1.49601`) from
correctly replicated records. Twist arrived, joint moved, segment never
re-derived.
Rules:
(a) **Never hand-compose `GetSegmentToEntity() × localToWorld`.** Call
`GetSegmentToWorld` — it is the binary's own path and it does the refresh.
(b) **Do NOT "fix" a stale transform by forcing the dirty flag.** Setting
`ModifyJoints(True)` at the read site made the symptom go away and scored
identically to the faithful fix — it was a stand-in that patched ONE
consumer and left every other peer segment reader stale. The binary only
ever *tests* that flag.
(c) A cached-transform bug is **master/replicant asymmetric by construction**.
If a geometry symptom is reported "peer POV only", suspect a cache that the
local render pass refreshes for free — before suspecting replication. Here
the replication was provably fine.
(d) When a fix lands at a partial percentage, **check whether the failures are
interleaved or a PREFIX** before calling it partial. These were a clean
prefix that ended the moment the peer first had a non-zero twist to carry —
i.e. the fix was complete and the remainder was correct behaviour. Reporting
it as "64% fixed" was wrong.
(e) Related probe trap: `Torso::PushTwist` sampled ONE shared static every 30th
call. With a master torso and a copy torso ticking 1:1, every 30th call is
always the SAME instance — the probe showed only the local untwisted torso
and hid the copy's writes entirely. Sample **per instance-kind** whenever
master and replicant objects share a diagnostic. (See also §gotcha on
process-wide statics serving the player's data as the replicant's.)
## 29. A peer mech does NOT tick before RunningMission — bench-only, and it fakes a replication bug (#148, 2026-08-08)
`Entity::Execute` (`ENTITY.cpp:556`, real engine source [T0]) calls
`PerformAndWatch` **only** when
```cpp
application->GetApplicationState() == Application::RunningMission
|| application->GetApplicationState() == Application::EndingMission
|| IsPreRunnable()
```
otherwise it just does `WriteSimulationUpdate`. `Entity::DefaultFlags` is
`DynamicFlag|MasterInstance` — **no `PreRunFlag`**; only `Player` and `Director`
add it in their DefaultFlags, and `Mech::Reset` sets it for a reset MASTER
("a reset master must tick"). A **replicant mech never gets it.**
So during `LoadingMission` / `WaitingForLaunch` / `LaunchingMission` a peer mech
performs **zero** subsystem ticks, no matter how much correctly-replicated data
is arriving for it. Measured on the observer node:
```
235 [perf-first] mech 3:161 master <- own mech, immediately
402 [torso-rec-rx] <- peer's torso records start arriving
2754 [perf-first] mech 2:55 REPLICANT <- peer's FIRST performance
2758 [torso] PushTwist COPY <- its torso ticks 4 lines later
2761 [ent-exec] state=5 <- RunningMission
```
This is correct engine behaviour, **but it silently corrupts any bench that acts
before the round starts.** `BT_AUTOFIRE`/`BT_GOTO` begin immediately, so early
salvos measure a peer whose torso, gait and subsystems have never run — and the
result reads exactly like a replication failure. It cost a full investigation
(filed as #148) before the app-state trace showed the peer was simply not
executing yet.
Rules:
(a) **Judge a 2-node bench by PREFIX vs INTERLEAVED, never by raw percentage.**
A clean leading run of failures that stops for good is almost always the
pre-`RunningMission` window; interleaved failures are the real thing.
(b) When a peer looks inert, check `[ent-exec] state=` before suspecting
replication. States: `2` LoadingMission, `3` WaitingForLaunch,
`4` LaunchingMission, `5` RunningMission.
(c) Prefer benches that wait for `RunningMission` before acting — or slice the
log at the transition — otherwise every peer-side metric carries this bias.
(d) The receipts that make this legible: `BT_NET_TRACE` gives `[upd-repl]`
(offered to the performer), `[ent-exec]` (state / preRun / instance) and
`[perf-first]` (one-shot per mech: entity ID + instance at its FIRST
performance). Anonymous per-frame receipts are useless in a 2-node log —
**name the mech.**
## 30. A finite-difference cache the binary re-seeds at Reset — transcribe the WHOLE seed list (#137, 2026-08-09)
The binary `Mech::Reset @0049fb74` opens with more than the obvious origin writes: its SECOND
instruction is `FUN_00408440(mech+0x58c, param_2)` — re-seeding the **previous-position memory**
of the AccelerationLastFrame ring feed (+0x81c/0x824/0x828/0x82c) to the new origin. The port
reconstructed the ring itself faithfully (ctor `part_012.c:9836`, derivative `:15169`) but its
Reset never got that one line. Result: the first post-respawn sample computed
`|newPos − prevPos| / dt` = **teleport distance / dt ≈ 1e5** into the velocity ring; the
ring-mean derivative turned it into an acceleration spike (with an opposite-sign ECHO ~15 frames
later as the sample rotated out of the mean); the myomer heat integrator's
`termAccel = (1−accEff)·|v|·|a|·m·dt` turned THAT into a ~3e9 one-tick heat deposit; and the
freshly-reset myomers snapped from 77 to ~9000 against failT=2000 — the #137 respawn freeze.
Rules:
(a) **When the binary's Reset writes a cell you don't recognize, that write IS the spec.** The
+0x58c re-seed looked like bookkeeping and was silently dropped; it was the only thing
standing between a teleport and a position-derivative spike. Transcribe the whole zero/seed
list, then map each cell — never the recognizable subset.
(b) **Any prev-value cell backing a finite difference must be re-seeded at every discontinuity**
(teleport, warp, respawn). If you add such a cache port-side, grep the binary's reset for its
analog before assuming none exists.
(c) **Derived state hides stale backing state.** `currentTemperature` sampled AT the reset read
77 (clean) because RTIS wrote it — while the freeze arrived one frame later through
`heatEnergy += pendingHeat` from a live producer. Probing the derived cell at the reset
instant proves nothing about the producers; trace the WINDOW after, per producer.
(d) The diagnosis chain that worked, for reuse: roster-wide state snapshot (at-death / at-reset /
post-reset) → eliminate conduction by trapping flows with full operands → trap the remaining
producer's deposits with operands → cross-reference the operand SHAPE (pure local −z,
magnitude = distance/dt, echo at ring-length) against the writers. Each trap eliminated a
theory the previous data had made plausible; three plausible theories died on operands.
## §25 — A same-pass edge latch sampling DEFERRED state: synchronous in the binary, next-tick in the port
**(2026-08-11, the #162 4-node retest double-credit.)** The binary's death processing writes
`movementMode 9` **inside the damage pass itself** — its own tail gate (part_012.c:14761) reads
the mode already flipped in the same call. The port put the mode write in the per-frame
`UpdateDeathState`, one tick later — and a comment at the death tail *asserted* the write was
synchronous, so nobody looked. Consequence: TWO lethal deliveries of one salvo (direct + splash,
2 ms apart, no sim tick between) each sampled `destroyedAtEntry = (mode==2||9)` as 0 and re-ran
the whole death block — duplicate kill credit + duplicate VehicleDead. Invisible at 2 nodes
(clean kills deliver ONE lethal hit); needs crowds + overlapping splash — the 8-player field
shape. **Rule:** when a binary function's OWN later code observes state it wrote earlier in the
same pass, the port's write must be equally synchronous — a per-frame deferral silently converts
an edge latch into a race. Sibling of the alarm-vs-mode trap (#108/#162): both are "the latch
sampled a cell whose write timing differs from the binary's". Fix shape: run the once-per-death
transition inline at the destruction edge (mech.cpp death_tail → `UpdateDeathState(0)`), keep the
per-frame caller for maintenance. Verified: kd4_bench 9/9/9/9 + kd8_stress 26/26/26/26, both
SWALLOWED=0 (the receiver dedup tripwire now never fires — no duplicate is ever GENERATED).

## Mech ARMOUR DARKENING (the .DZM material-damage system) — RECONSTRUCTED 2026-07-31 (Gitea #87) [T2]
A mech's armour panels **darken as their damage zone takes damage** — a per-zone, per-material
colour ramp-down, NOT a texture swap, a filter, or geometry. Players reported the port showing only
the limb swap ("the actual enemy mech in external view is not showing darkened armor panels").
**The 1995 chain** [T1]:
- **`.DZM`** (`VIDEO\<mech>SKIN.DZM`, 40 shipped) lists, per damage zone, the materials that zone
paints: `[dz_ltorso] material=avaskin:avat2_dz_ltorso_mtl`. One file per SKIN VARIANT — the
`dzm`/`dzms`/`dzmt`/`dzmo`/`dzma`/`dzmb`/`dzmc`/`dzmd` key family (same suffix set as the
`destroyed`…`destroyedd` video variants); the res-compiler address is UNKNOWN (the old
`FUN_0041e4e0` citation was WRONG — that is `DamageZone::TakeDamage`; corrected 2026-08-02,
swept with [[decomp-reference]]).
- Compiled into BTL4.RES and parsed by **MUNGA's own `DamageZone` stream ctor** into
`materialTable`, keyed by `EntitySegment::SkeletonType` (`engine/MUNGA/DAMAGE.cpp:311-336`,
`GetMaterialList(skl_type)`) — real engine source [T0]. **This data was loaded and unused in the
port all along**; only the consumer was missing.
- **`BTL4VideoRenderer::MakeMechRenderables` (`FUN_004cef28`)** walks the zones and builds, per
(zone, material), a 232-byte watcher **`FUN_004573e4(material, &zone->damageLevel, 0.1f)`**

(`0x3dcccccd`), and **`FUN_00457784`** re-pushes `lerp(pristine, damaged, damageLevel)` whenever
the level changes (constant `@0x4579a4` = **1.0**). So a zone at full damage renders at **10%**
of authored brightness, continuously interpolated.
- **Faithful quirk:** Opacity is read and lerped but **never written back** — only 13 of the 16
values are pushed (`dpl_GetMaterialOpacity` has no matching Set call in the watcher).
**NOT the mechanism** [T2]: the engine also has `SV_SPECIAL DAMAGE <material>` /
**`dpl_Damagize` `FUN_004902b0`** (punch's sibling — same VPX cmd 0x20, tokens
`f_t_dam(0x92)/sca(0x05)/undamage(0x04)`, dispatch @0x4599ae; error *"SPECIAL GEOGROUP DAMAGE
couldn't find material"*). A scan of **all 879 shipped BGFs finds ZERO `DAMAGE` tokens** — the path
exists in the engine but no shipped asset uses it. Don't chase it.
**The port** (`game/reconstructed/btl4vid.cpp` `BindArmourDamage`/`TickArmourDamage`,
`engine/MUNGA_L4/L4D3D.cpp`): batches now carry their AUTHORED (pre-substitution) material name
(`BgfDrawBatch::matName` -> `L4DRAWOP::dzMatName`); binding resolves the .DZM lists onto real draw
ops once per tree build, and the per-frame tick (driven from `Mech::PerformAndWatch`, EVERY mech)
copies `zone->damageLevel` onto them. Two hard-won details:
- **Key the material list on `viewSkeleton`, not the build `skeletonType`.** Each skeleton variant
is painted from its own skin library (Black Hawk N = `blhskin:`, X = `blxskin:`) and
`ApplyViewSkeleton` reloads every segment mesh; keying on the build skeleton matched a list
belonging to geometry that is not on screen -> **zero bindings, no darkening**.
- **Scaling the `D3DMATERIAL9` is inert** — see gotcha **§23** (`DIFFUSEMATERIALSOURCE` defaults to
vertex colour). The darkening is applied as a `TEXTUREFACTOR` modulate on texture stage 1.
Rebinding runs after every geometry swap (`RemakeEntityRenderables`, `ApplyViewSkeleton`), which
also keeps `segPick` (the #73 aimed pick) off discarded meshes.
Bench: `scratchpad/night7/armor_darken.sh` (self/enemy/ext legs) + `armor_ab.sh` (forced-level
pixel A/B). Gates `BT_ARMOR_LOG` / `BT_ARMOR_FORCE=<0..1>`. Verified: 57 bindings on the enemy
mech, brightness tracking `1 - 0.9*level` exactly, hull 0.35x vs terrain control 0.98x at level 1.
The `damcolor_`/`gen*gry_` arm+gun names go unmatched until the DESTROYED limb variant loads —
correct: those materials live on the `*D*.BGF` damaged meshes.
## SEARCHLIGHT -- the pod's night kit, RECONSTRUCTED 2026-08-05 [T1 decode, T2 both benches]
The subsystem (searchlight.cpp: sim @4b841c, ToggleLamp @4b838c toggles requestedOn@0x1E0 --
NO novice gate, that's ThermalSight's; lightState = requested && powered(4) && heat<2 && alive,
published as the "LightOn" attribute + replicated as subsystem record 0x14) was already complete;
the VISUALS were the gap, decoded from MakeMechRenderables @004cef28 `case 0xbd8` [T1]:
- **Cockpit = a FOG SWAP, not a light.** The @00456778/@00456814 watcher polls up to two LightOn
attrs; either-on -> `SetFogStyle(searchLightOnFogStyle)` (the authored `fog=` set), off ->
`searchLightOffFogStyle` (the `nosearchlightfog=` set). Both sets are authored per
map/time/weather page in BTDPL.INI (arena_night 40/400 lit vs 5/400 dark; des_night 100/1100
vs 30/700; arnitclear 90/1100 vs 5/1000). The 2007 engine kept the whole system under its real
names (searchLightFog*/noSearchLightFog*, the FogStyle enum); the port completed the stubbed
plane application (currentFogNear/Far now swap with the style) and transcribed the watcher into
`TickSearchlight` -- including the ctor's INVERTED cache seed, whose first-tick "change"
normalizes a night start onto the DARK set. Fidelity consequence: every prior build rendered
the lit fog permanently (nothing called SetFogStyle(3)); authentic night starts darker.
Glass key: F5 -> streamed button 0x14.
- **PERCEIVED STRENGTH [T2 field eyeball 2026-08-05]: authentically SUBTLE.** With LINEAR fog the
near-plane move barely changes close-range haze (at 30u the arena pair differs ~5%); the swap
reads as a modest push-back of the night murk at mid/long range, NOT a flashlight. Geometry
brightness comes from the page's ambient= + ramps and never changes with the lamp -- a close
wall is identical lit/unlit. First eyeball matched exactly ("kinda sorta illuminates the
area... didn't illuminate the wall" -- that IS the 1995 behavior). No illuminating dynamic
light exists anywhere in BT's render path: ChildLightRenderable has ZERO instantiations
engine-wide, and the FUN_0048d060 cluster (@4568f8/@456a0c/@456b4c/@4586d0) is light-POINT
sprites (beacons/nav strobes, palette-tinted), not geometry lights. Set player expectations
in the release notes accordingly.
- **External = the spot.bgf beam-cone mesh** (VIDEO/GEO + per-time variants), hung as a child of
the searchlight SITE joint (mount = subsystem `mountSegment`@0x1DC == resource segmentIndex;
madcat 20, loki 21), shown/hidden per frame from the replicated LightOn (@0045612c watcher ->
the SetDrawObj swap). Site segments now build geometry-less DCS children (posed + parentable --
the 1995 graph gave every site a DCS node; our tree used to skip sites entirely; this also
enables future site-hung effects). Wrecks go dark through the authentic gate (host shutdown
forces lightState 0). Cross-node verified: B presses, A logs `[spot] cone SHOWN (seg 20)`.
- Benches: `scratchpad/night12/searchfog.sh` (solo cockpit chain + red-fog end-to-end probe),
`spotcone.sh` (2-node cone + replication). BEAM MATERIAL decoded 2026-08-06 (b75bb4a) [T1]:
SPOT.BGF is a 7-vert cone ~50u forward and ~35° DOWN (a ground-pool lamp, not an air beam),
verts tinted cyan-white; its material class `btfx:brighten.25` smuggles the ADDITIVE factor
in DIFFUSE.r (0.25) with a warm emissive on the night page — the loader draws brighten*
batches as an additive veil (dest += vertexRGB × factor, blend pass, unlit); tint compose
(vertex cyan vs night emissive warm) [T3], flagged in the L4D3D draw branch. Look pass
ACCEPTED by field eyeball 2026-08-06 (translucent beam reads correctly; solo rig

## THE GAP CENSUS + RE-EXPORT (2026-08-06, #60) — BOTH HALVES DONE [T1]
**The export was REBUILT 2026-08-06** (Ghidra 12.1.2 headless + `ExportGaps.java`'s gap-fill
pass): index coverage **87.3% → 93.5%**, dark real code **90.4 KB → 40.8 KB (54.8% recovered)**,

TriggerState and `**(mech+0x128)` is the CONTROLS MAPPER's button roster (proven by the
MECHWEAP.CPP assert string + the trigger-edge detector @004b9608 adjacent).
**⚠ SAME-DAY CORRECTION (the seek audit): the binary DOES have a dynamic myomer→speed feed —
it lives in the un-exported master-perf gap** (@0x4a9cf2-0x4a9da4, raw capstone; the same gap
that hid the #93 crash block). Per frame: MAX `speedEffect@0x31C` over the myomer chain
(+0x7AC) → `mech+0x79C` → **`mapper->speedDemand@0x128 *= it`**, and at |drive| ≤ 1e-4
(@0x4ab16c) the mapper's `turnDemand@0x12C` is ZEROED — dead/overheated myomers freeze speed
AND turn. The morning's "no feed" verdict was export-gap blindness (text sweeps cannot see
un-exported functions; the decisive tool was a raw-image capstone scan for FPU reads of
+0x31C). Field truth agrees: Oracle (pod veteran) — seek-4 humanoids ran 182 kph (the
manual's printed Super Charged figure), overheat = "freezing up". The port restored the
demand scale byte-grounded (mechmppr.cpp): MAX over the chain, UNCLAMPED (gear 4 rides ~1.43×
demand into the RegisterMaxOutput cap = SUPERCHARGE), turn-freeze included; damage slows
(speedEffect carries 1−damage — gitea #75's original premise was RIGHT).
The rest of the myomer system, all live in the port:
1. **Heat** — the drive-heat integrator (#85, below).
2. **Vital death** — myomers are the ONLY `vital=1` subsystem in the authored records
(BTL4.RES `res+0x48` scan): destroying them KILLS the mech (the #80 vital-crit path). This
is also the collision ram-death mechanism (myomers are a 0.35-weight rattle target).
3. **The assembly cap** — `RegisterMaxOutput @004b8ef0`: `mech+0x7A0 = max(cap,
AvailableOutput(topGear))` = base × ~1.4284, the gait rise-clamp both channels bound
against (part_012:12103/12334). Port: each myomer registers per tick (idempotent max();
the 0x358 layout lock leaves no latch room) — state-identical to once-at-assembly. The
old per-frame `reverseSpeedMax2 = reverseStrideLength` heal (which would have clobbered
it) is garbage-guarded only now. `Mech+0x34C` (base) = port `reverseStrideLength`,
`Mech+0x7A0` (cap) = port `reverseSpeedMax2` — both documented misnomers.
4. **The ENG-page power curve** — SeekVoltageResponse, now at the correct absolute scale
(OwnerBaseSpeed reads the real base instead of the 1.0 stub).
5. **Electrical sourcing — the dial's REAL stake is TORSO TWIST.** A gear's voltage must be
<= the generator's measured output (`(1 − generator damage) × rated`, thermal breaker on
FailureHeat with recovery gated on NormalHeat — trip at T>2000, re-arm at T≤1000, exactly
the manual p23 "cooled down half way" rule; full trip/recovery/warning-edge audit in
[[decomp-reference]] §Generator trip/recovery (#154); there is NO load model — demand
never pulls the bus down), or the myomers leave
Ready. The Torso is a PowerWatcher on the myomers: `TorsoSimulation` ZEROES the twist rate
while the watched myomers are not Ready (halves it at DegradationHeat) — so an over-high gear
on a damaged generator freezes the pilot's AIM until they downshift. On a healthy mech,
gears 1-3 are literally identical (heat ratio floors at 1, no speed coupling); gear 4 =
double heat + a tighter dropout threshold for nothing but the taller graph — a trap.
(A `speedDemand *= speedEffect` multiplier was removed in the morning commit and RESTORED,
byte-grounded and improved, the same day — see the correction above. Verified live: healthy
drive=1.0, collision-rattled myomers drive 0.89→0.74 with demand scaling in lockstep.)
**✅ MYOMER DRIVE HEAT LIVE (#85, 2026-07-31) [T2].** The five Mech motion operands of the
drive-heat integrator `@004b8d18` were `return 0.0f` cross-family shims, so the (fully
reconstructed) integrator accumulated `ratio² · damageGain · 0` every tick — myomers ice cold at
any seek (Oracle's night-7 panel-confirmed report). Operands re-grounded from the raw disasm +
the decomp and mapped to named members via the complete-TU bridge `BTMechMyomerMotionSample`
(mech4.cpp): `+0x1C4` vec = `localVelocity.linearMotion`; `+0x82C` vec =
`localAcceleration.linearMotion` (the authentic 15-ring smoothed AccelerationLastFrame);
`+0x20C` = `moverMass` (the collision divert's cell — the old "motion gain" label was wrong);
`*(+0x250)` = the environment **gravity pointer** (`FUN_00421e2c` does `vy -= **(+0x250)`/tick).
Physics: `heat += ratio²·(1+dmg)·[0.005·½mv² + 0.2·m·g·|vy|·dt + 0.2·m|v||a|·dt]` — kinetic work
+ climb power + acceleration power. The binary `fabs`es v.y (the port's old draft didn't).
**Authored tuning extracted from BTL4.RES** (all 18 mech variants share one record):
VelocityEfficiency=0.995, AccelerationEfficiency=0.8, seek gears 0.3/0.5/0.7/0.9999 rec idx 2;
myomer thermal profile startT=77 / degradation=1000 / failure=2000 / conductance=1.9e5 /

circling drove T 77→1225 (past degradation) and the coolant loop pulled it back to ~520
equilibrium on slowing. ⚠ Two carried caveats: (1) the kinetic work term has **no dt** in the
binary (per-tick accumulate, a 1995 fixed-frame assumption) → heat/s scales mildly with frame
rate; kept verbatim, field-calibrate against pod veterans. (2) the climb term is wired but
inert: `Mover::localEnvironment` is never populated in the port (EnvironmentZone res type 23

**zone's** `TakeDamage` (zone vtable `+0x18`, *not* the subsystem's `+0x24`). Reading it as
"an un-powered myomer heals" is the evident intent, but it can never fire: a subsystem's private zone
comes from the 2-arg `new DamageZone(this,0)`, and `engine/MUNGA/DAMAGE.cpp:187-190` zeroes **all five**
`damageScale[]` entries; `Reset()` never touches them and the only other writer is `Mech__DamageZone`
(the mech's *streamed* zones — `mechdmg.cpp:246-253`). Since `TakeDamage` is
`damageLevel += amount * damageScale[type]`, the sum is always `+= amount * 0`. Confirmed by
experiment: seeded to 0.6 and held at NoVoltage ~1500 ticks, `damageLevel` never moved.
Reconstructed and deliberately NOT "fixed" — inventing a working repair would be made-up behavior.
**General rule:** you cannot damage a subsystem's own zone through `DamageZone::TakeDamage`; the crit
path writes `damageLevel` directly (`DistributeCriticalHit` pins `*(this[0x38]+0x158) = 1.0f`).
✅ **CORRECTED 2026-07-29 (#80): `@004b8bb9` — the un-powered self-repair — is LIVE, in 1995 and

original: the frozen-at-0.6 experiment was measuring a PORT bug (the subsystem ctor wrote the
zone's armour/scales through the `ReconDamageZone` proxy at struct offsets +4/+8 instead of the
engine members at +0x140/+0x144, so the real `damageScale[]` stayed zero). The binary ctor
(`@0x4ac7bb`) initializes them from the resource keys `WeaponDamagePoints` + the five per-type
`...DamagePoints`; the port now does the same through the engine's named members, and the CSS
parses the keys. An un-powered, not-yet-destroyed myomer heals at `0.011 × damageScale[Explosive]`
per tick. The retracted "cannot damage a subsystem's own zone" rule is superseded — see
[[combat-damage]] §CORRECTED for the full mechanism (this also revived the crit sink, #80).
Also un-stubbed here: `Myomers::DamageStructureLevel()` returned a hardcoded `0.0f`, which pinned

## Coolant LEAKS (Gitea #88 fix, 2026-07-31) — the #64 shadow was the single break [T2]
`HeatSink::UpdateCoolant` (@004adbf8) prices the damage-driven leak: `coolantDraw =
ownZone->damageLevel × heatLoad`, floor 0.0025, and the `coolantActive@0x138` hysteresis

The read is the **qualified ENGINE member** `Subsystem::damageZone@0xE0` — which the port's
MechSubsystem ctor never assigned (it filled only its re-declared shadow, gitea #64 / gotcha #1),
so `zoneDamage` pinned 0 and a leak was **structurally impossible** regardless of damage. Fixed by
ALIASING the engine base member to the same zone in both MechSubsystem ctors (mechsub.cpp) — every
shadow reader is untouched (same object), the engine base `Subsystem::TakeDamage` null-AV is
disarmed, and the #64 full de-shadow sweep remains the long-term cleanup. Verified live: collision

## Myomer drive-heat calibration — VERIFIED FAITHFUL (2026-08-09, #137) [T1]
The integrator `@004b8d18` accumulates into `pendingHeat@0x1C8`:
`gear² × (1 + X) × [ (1−velEff)·|vy|·m·g·dt + (1−velEff)·work + (1−accEff)·|v|·|a|·m·dt ]`
with `work = mass · |v|² · 0.5`. Its constants, read byte-exact from `.rdata`
(`section_dump.txt` row ` 4b8ee0 5dc30000 0000003f 00000000 0000803f`):
**`_DAT_004b8ee4` = 0.5f** (the kinetic ½), **`_DAT_004b8ee8` = 0.0f** (the `Abs()` idiom),
**`_DAT_004b8eec` = 1.0f** (the `1 − efficiency` complements and the gear-ratio clamp floor).
All three match what the port computes — the formula and its authored inputs
(VelocityEfficiency 0.995, AccelerationEfficiency 0.8, thermalMass 2.5e5, myomers linked
Condenser5) are reconstructed correctly.
**The one deliberate deviation, and why it is the faithful choice.** The binary applies **no
`time_slice`** to the kinetic term (`fVar5 * fVar1`) while the climb and accel terms both carry
`param_2` — it is a per-frame energy add at the pod's **fixed ~28 Hz**. The port uses
`work × (time_slice × 28)`, which is *identical* at 28 Hz (`dt·28 = 1.0`) but holds the same
heat-per-SECOND at any frame rate. A literal transcription would add the full term once per
frame, so at 170 fps it would inject ~6× the heat the pod ever did. `BT_MYO_HZ` overrides the
reference rate for bracketing.
**Consequence for #137 — CORRECTED 2026-08-09, the paragraph that stood here was wrong.** The
"players read 'respawned with heat maxed' as acceleration to top speed" claim did not survive
the data: the deposits were e9-scale within 30 frames of the reset, physically impossible from
motion input (~6.5e5/frame ceiling). The actual cause was a **dropped binary re-seed**: the
binary Reset's second instruction (`FUN_00408440(mech+0x58c, origin)`) re-seeds the
previous-position memory of the AccelerationLastFrame ring feed (+0x81c..+0x82c); the port
reconstructed the ring but not the re-seed, so the first post-respawn sample computed
TELEPORT-DISTANCE/dt (~1e5) into the velocity ring, the ring-mean derivative spiked
`AccelerationLastFrame`, and `termAccel = (1-accEff)·|v|·|a|·m·dt` deposited ~3e9 into
`pendingHeat` in one tick → myomers snapped from 77 to ~9000 (failT 2000) → speedEffect 0 →
frozen until cooled. Fixed by restoring the re-seed (`accelPrevPos = origin.linearPosition` in
Mech::Reset). The ~8% field rate was the |v| factor: only pilots whose throttle was still
forward at the respawn (physical lever / HOTAS — exactly who reported it) had gait-republished
speed in the spike frames. The calibration facts above (constants byte-exact, dt-normalised

# The Test Harness — how benches run, and what counts as verified
Two subjects, deliberately in one file: the MACHINERY (how to launch and read a
bench) and the DOCTRINE (what a bench must show before a fix may be called
fixed). The doctrine exists because the machinery was used wrong more than once.
## THE DOCTRINE: verify the FIELD COMPOSITION, not a constructed proxy
**The archetype failure (#86 → #110).** "Weapons on damaged arms keep firing"
was fixed and verified by destroying the WEAPON directly (`BT_KILL_SUBSYS`).
The field scenario was the ARM ZONE dying while the weapon stayed healthy — a
path the bench never took. The claim "fixed" stood for two playtests while the
players kept hitting the bug; the actual defect (a stubbed cascade walk,
gotcha #26) sat exactly in the gap between the proxy and the field. **A fix
verified only against a reproduction you constructed is not verified.**
Rules, in order of application:
1. **Reproduce the reported scenario first** — the player's composition, not a
convenient adjacent one. If the report is "peer's arm shot off in MP", the
proof is a two-node run where PEER FIRE kills the arm (`mp_armgrind.sh`),
not a solo self-damage run.
2. **Scalpels are for isolation, not for verdicts.** Deterministic hooks
(`BT_SELF_DAMAGE_ZONE`, `BT_KILL_SUBSYS`, `BT_FORCE_SEEK`, `BT_ARMOR_FORCE`)
are the right way to LOCATE a defect. Before a scalpel result supports a
"fixed" claim, prove PATH IDENTITY to the field composition (e.g. the
self-damage harness dispatches a real `Entity::TakeDamageMessage` — the
same message + handler a peer round takes — so the scalpel shares every
line from the handler down; verified 2026-08-02, and then the field
composition was STILL run).
3. **If the symptom is multiplayer, the proof is two nodes.** Master-side
correctness says nothing about what a peer sees; replication is its own
layer (records, edge-detects, instance gates). #94, #84 and #110 each had a
peer-side half invisible to any solo bench.
4. **If the symptom is visual, the proof is pixels** — `BT_SHOT_EVERY` frames
diffed against a control region, not a log line saying the value changed
(gotcha #23: a colour change that logs perfectly and renders nothing).
5. **Coverage claims need a sweep, not an instance.** "Works for every weapon
type / chassis" = enumerate the axis and measure each point (all 3 fire
gates through a zone death; all 8 chassis' authored cascade flags —
`zonesweep.sh`). Per-chassis behaviour usually lives in AUTHORED DATA, so
fixed code on one chassis proves nothing about the others.
6. **Chase every anomaly in a passing run to ground.** The Owens rack cascade
also killing the sensor suite looked like a walk bug; it was authored
skeleton data (the mast is a child of the rack). A pass with an
unexplained extra effect is not yet a pass.
## THE MACHINERY
### The contract: `scratchpad/night6/bench_common.sh`
The single source of truth for launching a node THE WAY A PLAYER'S SHORTCUT
DOES — read the file, its comments carry the incident history. Summary:
- `bt_player_env` — `BT_PLATFORM=glass`, `BT_START_INSIDE=1` (cockpit, not
chase cam), `BT_DEV_GAUGES=1`. Copied verbatim from the shipped .bats;
`bt_assert_player_env` warns on drift.
- `bt_launch <log> <egg> <affinity> [args]` — one node, env-scoped, PID
tracked in `/tmp/bt_bench_pids.$$`.
- `bt_expert_egg` — shipped eggs are ALL `experience=expert`; a novice egg
silences heat/crits/jams and is only legal for the gimp bench (which must
say so out loud). See [[experience-levels]].
- `bt_kill_ours` — teardown kills ONLY this run's PIDs (a blanket
`taskkill /IM` once shot down two live sessions).
### Single-node bench skeleton
```bash
. /c/git/bt411/scratchpad/night6/bench_common.sh
cd /c/git/bt411/content || exit 1
taskkill //F //IM btl4.exe > /dev/null 2>&1; sleep 2 # stale-node clear
sed "s/^map=.*/map=grass/; s/^time=.*/time=day/; 0,/^vehicle=.*/s//vehicle=$V/" MP.EGG > X.EGG
export BT_<gates>=... # diagnostics + scalpels
bt_launch x.log X.EGG 0x03
sleep <duration>; taskkill //F //IM btl4.exe; sleep 2 # then grep x.log
```
The vehicle sed must replace the WHOLE line (`s/^vehicle=.*/`), or you mint
`vehicle=thr1bhk1` and the spawn FATALs. Chassis codes: ava1 bhk1 lok1/2 mad1/2
own1 snd1 thr1 vul1 (own1 has NO arm zones — rack zones instead).
**Weapon/combat benches need `map=grass time=day`.** `MP.EGG` authors
`map=cavern time=night`; a bench that copies it without the map sed (e.g. via
`bt_expert_egg` alone — mp_double.sh has this gap) parks the GOTO-driven mechs
against cavern rock and they shoot terrain for the whole window. Always sed the
map/time on the COPY, single-node and two-node alike.
### THE ZONE-WALK MATRIX (`scratchpad/night10/zonewalk.sh`) — systematic
### per-panel hit-location testing, operator-watchable (built for #124)
The precision-targeting rig: **two nodes**. Node B (launched first, back
window) is the TARGET — `BT_SPIN_SELF=15` rotates its own viewpoint mech in
place (deg/s; the BT_SPAWN_AT write pattern, applied per frame) so every
aspect passes the shooter's boresight; its window shows its own paper doll
taking the hits (`BT_DMG_LOG=1` prints every `[dmghit]` with zone + level).
Node A (foreground — it owns the pick focus) runs `BT_ZONE_WALK=<secs/zone>`:
walks the target's damage zones in index order, resolves each zone's CARRIER
SEGMENT's live world position (`BTResolveSegmentWorld` — the same resolver the
attached smoke rides; zone→segment via the `BTMechZoneSegAndName` bridge),
SERVOS the torso twist + aim elevation until the centered reticle's pick ray
(`BTGetAimRay(0,0)`) points at the segment, then pulses the laser trigger 3×
and advances. `[walk] ZONE/FIRE/HOLD` lines on A pair with `[dmghit]` on B.
Launch: `bash scratchpad/night10/zonewalk.sh` (relay included; NO kill timer —
the session stays up for observation; teardown = taskkill btl4).
Node A also carries `BT_ARMOR_LOG=1` + `BT_SHOT_EVERY=300 BT_SHOT_PREFIX=zwA`
(added for #87): the armour watcher's `[armor] ... level P -> Q` lines on A are
the OBSERVER-side receipt that B's zone levels replicated (the walk is the
standing zone-replication bench — A-side peaks must match B's `[dmghit]`
finals), and the numbered captures are the pixel record of the enemy hull
darkening. Digest: `python scratchpad/night10/digest_walk.py` (per-zone hits,
amt/hit, level first→last on B; replicant peaks seen by A; zone-repl lines).
Companion scalpels: `BT_ASPECT_TEST=1` (the zero-premise frame probe — 4
world-cardinal self-impacts + one at each weapon's physical MUZZLE, the
left/right anchors that caught the #124 reflection-vs-rotation error);
`BT_AIM_SWEEP=<period>` (blind elevation sweep — superseded by the walker).
Hard-won constraints baked into the walker (do not relearn these):
- **Engage gate**: servo only when the aim ray is live AND range < 150 AND
|bearing| < 1.1 rad; otherwise RELAX the twist toward 0 and hold the zone
clock. Without it the servo winds the twist to its limit while the goto
marches (limit-clamp fight = the mech visibly SHAKES) — and the gate must
sit well above the goto's resting bearing error (~0.55 rad at STOP=90) or
it deadlocks in HOLD.
- **Yaw polarity**: the twist cell's angular sense is OPPOSITE atan2(x,−z)
world yaw (operator-observed live: `+=` turned the torso AWAY — the second
witness for the #124 SelectSlice twist-sign flip). The servo starts at −1
and carries a growth WATCHDOG that self-flips if the error diverges.
- **Damped servo**: gain 0.40, step cap 0.025 rad/frame, deadband — the aim
ray lags the twist write by a frame; full-error correction oscillates.
- **Approach port**: dropzones spawn cross-map; the walker one-shot teleports
A to 100 u off the target (BT_SPAWN_AT pattern incl. the +500 y ground-snap
lift) instead of minutes of marching.
### Two-node bench skeleton (the MP pattern)
```bash
bt_assert_player_env
bt_expert_egg MP.EGG X.EGG
BT_MP_LOG=1 <gates> bt_launch x_b.log X.EGG 0x0C -net 1601 # node B first
sleep 2
BT_MP_LOG=1 <gates> bt_launch x_a.log X.EGG 0x03 -net 1501 # node A
sleep 5
python ../tools/btconsole.py X.EGG 127.0.0.1:1501 127.0.0.1:1601 & # the relay STARTS the mission
sleep <duration>; kill $relay; bt_kill_ours
```
- A `-net` node renders NOTHING until `btconsole.py` (the headless relay)
starts the mission — a black window is pre-mission, not a hang.
- Affinity: TWO logical processors per node, disjoint sets (`0x03`/`0x0C`);
one LP starves the gauge executive ([[multiplayer]] peer-shakiness fix).
- Give the SHOOTER dense fire (`BT_AF_PERIOD=3` + `BT_AF_MISSILE=1`) and the
victim sparse (`=9`) when one side must lose a grind. Unthrottled autofire
trips the FailureHeat all-weapons brick and combat dies.
- Combat drive: `BT_GOTO=enemy BT_GOTO_STOP=<units>` — 100 ends in a visual
ram scrum; 180 gives a standing exchange.
- Read each claim on the node that can see it: damage on the VICTIM's log,
replication on the OBSERVER's (`[zone-repl]`, `[mlrec]`, mirrored `DET`s).
### Process hygiene (every one of these cost a session)
- **Stale-node taskkill FIRST.** A leftover node joins the next lobby as a
third instance and poisons the run.
- **Never double-background.** `run_in_background` + an inner `&` orphans the
script mid-startup: nodes launch, the script's own cleanup never runs.
- **Teardown kill order closes windows one at a time** — a "crashed" window at
the end of a timed run is usually the bench's own taskkill.
- **Stale exe:** `LNK1104` / a bench ignoring new diagnostics = the previous
process still holds `btl4.exe`, or the build silently didn't run — check the
`btl4.vcxproj ->` line printed, then rerun.
- **Editing source through bash-heredoc python collapses `\` one level** even
single-quoted -- a `"\n"` you meant as backslash-n arrives as a real newline,
the "fix" silently no-ops (`good == bad`), and the C2001 hunt repeats. Build
backslashes as `bytes([92])`/`chr(92)`, and verify a replace by LENGTH DELTA
or a re-read, never by the script printing "fixed".
- Bench artifacts (`*.EGG` copies, `*_NNN.png`, bench logs) must be deleted
from `content/` before any dist cut; field logs are never committed.
### Reading logs without fooling yourself
- **A capped/throttled diagnostic that is silent is NOT evidence of absence**
— the #99 `[seqrun]` shared counter "proved" a sequence never ran; it was
throttle starvation. Per-object throttles for per-object questions.
- **Alarm-line counters are not trend lines** — `free=0` printed AT the
failure is true by definition; the 30s census carries the trend (#32, three
separate times).
- **Log the actor's NAME at every refusal/decision** (`'PPC' fire REFUSED`);
anonymous counters (`FIRED #20`) cannot support attribution claims.
- Field logs have NO diagnostic gates set — a fix whose acceptance evidence
sits behind an env var is unverifiable in the field. Spawn-time summaries
(one line, ungated) answer questions retroactively; per-frame traces stay
gated.
## Bench-script gotchas (each has burned a session)
- **Write benches CLEAN, never sed-derive a chain** — sed-derived copies silently dropped envs
twice (the [replgimp] silence); export envs INSIDE the per-node subshell.
- **Absolute paths everywhere; `cd /c/git/bt411` first** — the cwd trap (heredoc python + `cd
scratchpad/nightN`) has broken later builds/appends with `fatal: pathspec`/`cannot stat`.
- **No apostrophes/backticks through bash heredocs** — write a `.py` file and run it (quoting has
mangled posted tracker comments and killed scripts mid-parse).
- **Drain stale watchdogs before relaunching** — a leftover waiter's `taskkill` has killed a live
bench mid-run.
- **Scripted input goes through the REAL seam**: `BT_BTNTEST`/`BT_BTNTEST2` (RIO queue → mode-mask
drain). In 2-node runs press at poll ≥900 — round-start jitter can eat earlier presses.
- **Capture the viewpoint that can see the change** (gotcha #13 bullet): cockpit view can't show
your own legs; pair screenshots with a state probe and READ a frame before concluding.
- **Build ritual first** — see [[build-and-run]] §Build ritual (stale exe = phantom results).
## The standing bench suite (scratchpad/night15/, 2026-08-11 wave — all hard PASS/FAIL)
| Bench | Asserts | Hooks it rides |
|---|---|---|
| `kd_bench.sh` (2-node) | K/D invariants I1-I5: deaths == PLAYER_DEAD == −500 costs == kill credits, no swallows | BT_AUTOFIRE + BT_AF_MISSILE, BT_GOTO, matchlog |
| `kd4_bench.sh` (4-node) | I1-I8 **receipt-derived per player** + bystander mirror convergence + no-mirror-exceeds-authority + zero `inst=R` | same + SBMIRROR records |
| `kd8_stress.sh` (8-node) | the same invariants under an all-vs-all melee (staggered salvo periods, one drop zone); `LOW STRESS` guard | same, 8 instances 1 core each |
| `proj_ttl_bench.sh` | #168 flight clocks: probe fizzles at exactly 5.0s / burn+10s; field phase: authentic ttl stamps, none early, no stale-point hits | BT_PROJ_TEST probe + BT_PROJ_LOG |
| `gen_edge_bench.sh` | #154 warning edge: 4/4 trigger fixups, trip edge FIRED, recovery + respawn silent | BT_GEN_HEAT injection + BT_AUDIO_EDGE |
| `xfire_bench.sh` | #165 destroyed-weapon gate: pre-kill FIRED, post-kill only REFUSED, survivor unaffected | BT_KILL_SUBSYS + named `[emitter] FIRED` |
| `eject_canary.sh` / `ram_bench.sh` / `relaunch_bench.sh` | eject suicide arithmetic / ram-rattle eligibility set / ordered-exit no-zombies | (night-15 fix wave) |
Multi-node rig notes: extend the egg by CLONING the 1602 pilot page (the kd4/kd8 scripts show
the python pattern); **only zone names the MAP defines are valid dropzones** (undefined names
pile everyone at a fallback — mechs spawn overlapping and the melee turns into splash-suicide
chaos, which the receipt-derived invariants still score exactly, but it isn't the scenario you
wrote); affinity masks 2-cores-each up to 4 nodes, 1-each at 8.

- **Renderer bypass: DONE** — `MUNGA_L4/L4D3D.cpp` + `DXUtils` replace libDPL / the IG board with

8 byte-identical field stacks (one player, Surface Pro 9 / **Iris Xe 128 MB** — the only GPU in
the fleet that ever actually loses the device): `ParticleEngine::Destroy +0x11`, `access=0
target=0x0`, from the per-frame render path. **Not a weapons bug** — the Owens two-trigger
missile+laser combo is merely what provokes the GPU timeout on that iGPU. The broken protocol
(both Present sites, inline copies): on `D3DERR_DEVICELOST` they called `Reset()` IMMEDIATELY —
which **always fails while still lost** (`V()` only logged) — then `ParticleEngine::Initialize()`
ran against the lost device, its creates failed and **NULLed the out-params** (verified: the bench
repro faulted at `target=0x0`, not a dangling address), and the NEXT lost frame's blind
`mVertBuffer->Release()` read a vtable at 0x0. FIX (`L4VIDEO.cpp` + `L4PARTICLES.cpp`): one shared
`DPLRenderer::BTResetLostDevice()` — release POOL_DEFAULT resources every lost frame (idempotent,
null-safe `Destroy`), **gate `Reset()` on `TestCooperativeLevel() != D3DERR_DEVICELOST`**, check
the Reset HRESULT, and on success re-create via **`CreateDeviceObjects()` — NOT `Initialize()`**,
whose `memset(mInstalledEffects)` silently killed every particle effect for the rest of the
mission on each reset that DID succeed (the quieter sibling bug). Draw paths guard the NULL buffer
(`ExecuteParticles` keeps draining particles while dormant). Bench: `BT_DEVICELOST_TEST` repro'd
the field crash byte-for-byte pre-fix, and post-fix the same shape logs `SURVIVED` + 3 forced
loss/reset cycles recover (`[render] device reset OK`).
⚠ **Discovery from the verify: `VIDEO\particles.png` has NEVER existed** — absent from the tree,
the RES, and all of git history — so `mParticleTexture` has been NULL on every machine since the
engine was written and **all billboard particles draw as untextured quads** (`SetTexture(0,NULL)`

particles everywhere. Filed on the tracker; a real texture (or the original particle sheet) is a
content task. Possibly related to the field "missile artifact looks wrong" observation.

## Phase 1 — four investigation lanes (raw returns)
########## LANE 0 ##########
## #154 — OUR PORT's generator trip/recovery reconstruction (raw findings)
### 1. Trip + recovery logic and thresholds
The generator's thermal trip lives in `Generator::GeneratorSimulation` — C:/git/bt411/game/reconstructed/powersub.cpp:1295-1372, transcribed from @004b1f7c (raw: reference/decomp/all/part_013.c:9049-9107, re-read this session).
TRIP (powersub.cpp:1304-1312):
```cpp
if (heatAlarm.GetLevel() == HeatSink::FailureHeat) // this+0x184 == 2
{
...
stateAlarm.SetLevel(GeneratorOut); // SetLevel 4
}
```
This is a HELD condition, not an edge: it re-asserts SetLevel(4) EVERY frame while heatAlarm==FailureHeat. Binary identical [T1]: part_013.c:9062-9064 `if (param_1[0x61] == 2) FUN_0041bbd8(param_1+0x7f, 4);`.
RECOVERY (powersub.cpp:1340-1357):
```cpp
case GeneratorOut: // 4
outputVoltage = 0.0f;
if (heatAlarm.GetLevel() == HeatSink::NormalHeat) // this+0x184 == 0
{
if (generatorOn == 0) { stateAlarm.SetLevel(GeneratorIdle); } // 1
else { startTimer = 0.0f; stateAlarm.SetLevel(GeneratorStarting); } // 0
}
```
Binary identical [T1]: part_013.c:9087-9097 (`param_1[0x61] == 0` gate, generatorOn at [0x75]). After the spin-up (`startTime <= startTimer`) it goes `SetLevel(GeneratorReady)` (2) and recomputes `outputVoltage = (1.0 - SourceLevel()) * ratedVoltage` (powersub.cpp:1316-1324).
The temperature thresholds behind heatAlarm (heat.cpp:851-862, @004ad924 [T1]): `T > failureTemperature → FailureHeat(2)`, `T > degradationTemperature → DegradationHeat(1)`, else `NormalHeat(0)`. Pure per-frame comparison, NO hysteresis. So: **trip at T > failureTemperature; recovery gate at T ≤ degradationTemperature** (all the way out of the yellow band, not just the red).
**The tester's era rule ("back online at HALF-cooled, when the red portion of the heat bar is gone") is SATISFIED by the port as built — no divergence.** The generator heat bar is a `VertTwoPartBar` fed `(currentTemp, degradeTemp, failTemp)` (btl4gau2.cpp:980-998); its Execute (btl4gaug.cpp:1321-1360, @004c48fc [T1]) tiles the bar up to the warn pixel `height*low/high` (low=degradationTemperature, high=failureTemperature) and paints `fillColor` only in the degradation..failure segment — i.e. the "red portion" IS exactly the T>degradationTemperature band, and it disappears exactly when the recovery gate opens. With the authored profile degradation=1000/failure=2000 (myomer record from BTL4.RES; generator values not separately confirmed [T3]) the warn line sits at literally HALF the bar. Oracle's 2nd/3rd tests ("came back after cooling halfway") behaviorally confirm the port already does this [T2-field].
### 2. stateAlarm writers, edges, and marks
Complete writer inventory of `Generator::stateAlarm` (@0x1FC, level cell @0x210):
- powersub.cpp:1311 `SetLevel(4)` — thermal breaker, HELD (per-frame re-assert while FailureHeat). The edge-ification happens inside the alarm: `GaugeAlarm54::SetLevel` (heat.hpp:106) `{ levelB = level; if (n != level) { level = n; NotifyWatchers(); } }` — notify ONLY on change, oldState (levelB@0x10) updated UNCONDITIONALLY. Byte-matches the binary FUN_0041bbd8 [T1] (part_002.c:5512-5546: `+0x10 = +0x14` before the equality check, then the three watcher sockets @+0x18/+0x2c/+0x40 fire only on change) and the T0 engine `StateIndicator::SetState` (engine/MUNGA/SIMULATE.cpp:155-217, including the "old state changes even on no-op set" NOTE at :176-179).
- powersub.cpp:1302 `SetLevel(1)` — held while `simulationState==1` (destroyed): a crit-destroyed generator is PINNED Idle forever (authentic).
- powersub.cpp:1321/1335 `SetLevel(2)` — spin-up / short-recovery completion.
- powersub.cpp:1346/1354 — the recovery arm above (4→1 or 4→0).
- powersub.cpp:1392 `SetLevel(3)` — HandleMessage msg 4 short (@004b21d0 [T1]).
- powersub.cpp:1212/1221 — ToggleGeneratorOnOff (@004b1ed0, raw re-read part_013.c:9016-9045 [T1]): OFF → SetLevel(1); ON → SetLevel(0) ONLY if heatAlarm==0 (hot ON-press changes NO state — see §4).
- powersub.cpp:1269-1270 — ResetToInitialState (@004b215c [T1]): SetLevel(0) then SetLevel(2) — every respawn passes through Starting then Ready.
- powersub.cpp:555 + :1564 — `ForceShortRecovery`/`PowerWatcher::HandleMessage` write `source->stateAlarm.SetLevel(3)` externally.
- `MarkGeneratorOut()` (powersub.hpp:483) via `BTGeneratorMarkOut` (powersub.cpp:1787-1791): **ZERO live callers** — the ForceCriticalFailure call was removed 2026-08-03 (mechsub.cpp:290-297).
**Edge delivered to audio:** the trip produces a synchronous `StateChanged(prev→4)` on the trip frame. Mechanism: `ATTRIBUTE_ENTRY(Generator, GeneratorState, stateAlarm)` (powersub.cpp:1051) publishes the alarm; `AudioStateWatcher` registers on the alarm's +0x18 audio socket (engine/MUNGA/AUDWTHR.cpp:918, with the T3 bring-up guard :908-917 that a constructed GaugeAlarm54 passes); `NotifyWatchers` (heat.cpp:96-111) Execute()s it inside SetLevel; `SendNotificationOfChange` (AUDWTHR.cpp:933-945) reads GetOldState()/GetState() at +0x10/+0x14 — layout verified compatible: StateIndicator : Node : Plug : RegisteredClass gives header 0xC then stateCount/oldState/currentState @0xC/0x10/0x14 + three sockets @0x18/0x2C/0x40 = 0x54, identical to GaugeAlarm54 (heat.hpp:126-138). State watchers are NOT on the per-frame poll socket (only `AudioTriggerOf`/`AudioMatchOf` call `simulation->AddAudioWatcher(this)` — AUDWTHR.h:293/:770; `AudioStateWatcher` registers only on the indicator socket), so no spurious held-state notifications.
**No ForceUpdate/updateModel/SetDirty mark exists at either edge** — grep of powersub.cpp finds none; the binary @004b1f7c has none either [T1]. The notification is purely the alarm-socket synchronous path.
**So the port's plumbing puts the notification on the TRIP edge (X→4), and also emits 4→0 then 0→2 at recovery.** Which of those the "Generator Out" SPEECH keys on is decided by the authored `AudioStateTrigger` fields (`triggerState/inverseTrigger/exclude_state`, streamed — AUDWTHR.cpp:968-990; firing rule :1046-1105 [T0]): non-inverse fires on `new_state==triggerState`, inverse on `old_state==triggerState` — an inverse trigger on state 4 fires EXACTLY on the recovery edge, which matches Oracle's symptom precisely. The port cannot flip this itself: the alarm mechanics are byte-faithful. The decisive probe is the load-time `[statecfg]` dump (AUDWTHR.cpp:981-987, env BT_ATTRBIND_LOG) — it prints every authored GeneratorState trigger's trigState/inv/exclude. Until that capture, whether the wrong edge is (a) authored-inverse consumed correctly (pod-era authoring quirk), (b) the trip-edge trigger authored against an attribute the port publishes differently, or (c) a dead START half of a start/stop pair, is undetermined FROM THIS LANE.
### 3. Divergence check vs the knowledge base
- context/decomp-reference.md:470-477 ("no Ready-case recompute"; stateAlarm 4's producer = the thermal breaker in GeneratorSimulation; the 2026-08-03 destruction→state-4 bridge removed as unfounded): **port conforms** — no Ready-case recompute exists in the port either, `BTGeneratorMarkOut` is dead code as documented.
- context/subsystems.md:103-105 ("(1 − generator damage) × rated, thermal breaker on FailureHeat; NO load model"): consistent with powersub.cpp:1322/1336/1398.
- One STALE-ish note found: powersub.cpp:1052's comment on GeneratorOn ("static until a shutdown writer drives it to 0") — the shutdown writer EXISTS now (ToggleGeneratorOnOff, powersub.cpp:1214/1223); the comment predates #53. Cosmetic.
- No divergence found between the port and @004b1f7c/@004b1ed0/@004b215c/@0041bbd8 — instruction-shape faithful on every path I compared [T1].
### 4. FailureHeat "permanent brick" family (open-questions)
The generator does NOT share a recompute path with the weapon FailureHeat family — three distinct recovery disciplines all reading the SAME producer (own HeatSink heatAlarm @+0x184, thresholds heat.cpp:851-861):
1. **Emitters** (@004baa88, emitter.cpp:225-229, :426-434): continuous per-tick gate — ResetFiringState + currentLevel=0 while heatAlarm==2, auto-resumes as soon as heatAlarm drops to 1 (DegradationHeat). Weapons recover at "red gone"; the generator demands full NormalHeat — an intentional binary asymmetry [T1].
2. **Launchers** (open-questions.md:1086-1102, projweap gate-1): a LATCH (weaponAlarm 7 roach-motel, re-asserted unconditionally), recovery ONLY out-of-band via the EjectAmmo tap (@004bb9b8) or reset — never by cooling. This is the documented "missile spam brick".
3. **Generator**: a state-machine arm (case 4) that self-clears at NormalHeat — the OPPOSITE of a latch.
Family resemblance that could explain the once-seen "stuck offline forever" (did not repro): the generator DOES have latch-shaped states with no thermal recovery arm, and both are binary-authentic [T1]:
- **The Idle park**: press generator OFF then ON while heatAlarm==1 (degradation band). The ON branch (@004b1ed0, part_013.c:9027-9033) sets startTimer=0 but does NOT touch stateAlarm when hot → parked at Idle(1) with generatorOn=1; case 1 has no restart arm; the FailureHeat re-trip doesn't fire (heat is only level 1). Recoverable only by another OFF/ON cycle after full cooling, or reset. Requires eng-page button presses — plausible for Oracle's first test.
- **Crit-destroyed generator**: `simulationState==1` pins Idle every frame (powersub.cpp:1300-1303) — permanently out, authentically. If trip #1 coincided with a generator crit, "never came back" is correct behavior.
- Non-button path: T parked in the degradation band forever keeps the breaker latched — but then the bar still shows red, contradicting "cooled off completely"; the bar and the alarm read the same currentTemperature, so this one is self-consistent and unlikely.
Bench hooks already in place: `[gen] X TRIPPED (T=...)` / `[gen] X RESTARTING (T=...)` under BT_HEAT_LOG (powersub.cpp:1308-1310, 1350-1352) give the exact trip/recovery timeline to line up against the audio.
--- KEY FACTS ---
* Trip: powersub.cpp:1304-1312 — stateAlarm.SetLevel(GeneratorOut=4) re-asserted EVERY frame while own heatAlarm==FailureHeat(2), i.e. currentTemperature > failureTemperature; binary-identical @004b1f7c (part_013.c:9062-9064) [T1]
* Recovery: powersub.cpp:1340-1357 — requires heatAlarm==NormalHeat(0), i.e. T <= degradationTemperature; then GeneratorStarting(0) -> spin-up startTime -> GeneratorReady(2) with outputVoltage=(1-SourceLevel())*ratedVoltage; binary-identical (part_013.c:9087-9097) [T1]
* heatAlarm thresholds heat.cpp:851-862 (@004ad924): >failureT=FailureHeat(2), >degradationT=DegradationHeat(1), else NormalHeat(0); NO hysteresis [T1]
* Era rule already satisfied: the generator heat bar (VertTwoPartBar, btl4gau2.cpp:980-998; Execute btl4gaug.cpp:1321-1360 @004c48fc) paints its fill ONLY in the degradationT..failureT segment — 'red portion gone' == T<=degradationT == the recovery gate; with authored deg=1000/fail=2000 the warn line is at half the bar [T1 code, T3 for generator-specific authored values]
* Alarm edge semantics faithful: GaugeAlarm54::SetLevel (heat.hpp:106) == binary FUN_0041bbd8 (part_002.c:5512-5546) == engine StateIndicator::SetState (SIMULATE.cpp:155-217): oldState:=current unconditionally, notify watchers only on change [T0/T1]
* Trip edge DOES notify audio synchronously in the port: StateChanged(prev->4) on the trip frame via the alarm's +0x18 audio socket (AUDWTHR.cpp:918, 933-945); recovery emits 4->0 then 0->2; layout GaugeAlarm54==StateIndicator verified (header 0xC, oldState@0x10, currentState@0x14, sockets 0x18/0x2C/0x40) [T0+T1]
* No ForceUpdate/updateModel/SetDirty mark at either edge in port or binary; AudioStateWatcher/AudioStateTrigger are NOT on the per-frame poll socket (only AudioTriggerOf/AudioMatchOf call simulation->AddAudioWatcher — AUDWTHR.h:293/:770) [T0]
* Which edge plays the voice is decided by authored AudioStateTrigger fields (triggerState/inverseTrigger/exclude_state, AUDWTHR.cpp:1046-1105): inverse trigger on state 4 fires exactly on the RECOVERY edge — matching Oracle's symptom; the [statecfg] dump under BT_ATTRBIND_LOG (AUDWTHR.cpp:981-987) prints every authored GeneratorState trigger config at load [T0 mechanism, T4 on which config is authored]
* stateAlarm=4 writers: ONLY the thermal breaker; MarkGeneratorOut/BTGeneratorMarkOut (powersub.cpp:1787) has zero callers since 2026-08-03 (mechsub.cpp:290-297) [T2]
* Stuck-offline candidates, all binary-authentic [T1]: (a) Idle park — generator ON pressed while heatAlarm==1: @004b1ed0 (part_013.c:9027-9033) sets no state when hot -> parked at Idle(1), no restart arm, FailureHeat re-trip cannot fire at level 1; (b) crit-destroyed generator pinned Idle every frame (powersub.cpp:1300-1303, simulationState==1)
* FailureHeat family recompute paths are DISTINCT: emitter auto-resumes at heatAlarm<2 (@004baa88); launcher latches weaponAlarm 7, recovery only via EjectAmmo tap (@004bb9b8) or reset (open-questions.md:1086-1102); generator self-clears only at heatAlarm==0 — shared PRODUCER (own heatAlarm) but no shared recovery path [T1]
* Weapons recover at DegradationHeat (red gone) but the generator requires NormalHeat — an intentional binary asymmetry, not a port bug [T1]
* Bench hooks: BT_HEAT_LOG prints '[gen] X TRIPPED (T=..)' / '[gen] X RESTARTING (T=..)' (powersub.cpp:1308-1310, 1350-1352) for a trip/recovery-vs-audio timeline [T2]
--- UNCERTAINTIES ---
* The authored AudioStateTrigger config for Generator.GeneratorState (triggerState/inverseTrigger/exclude_state values) is unknown from this lane — it lives in the 1995 audio stream; the BT_ATTRBIND_LOG [statecfg] load-time dump would settle which edge the 'Generator Out' speech keys on. Until then, whether the wrong edge is authored-inverse (STOP half of a pair firing as the only live trigger) or a dead trip-side binding is T4.
* Whether the 'Generator Out' voice is even bound to Generator.GeneratorState vs GeneratorOn (a live x4 attr that does NOT change on thermal trip) vs a PoweredSubsystem electrical-state attribute the binary published but the port does not (port publishes only InputVoltage on PoweredSubsystem, powersub.cpp:100-104) — unverified.
* Generator-specific authored DegradationTemperature/FailureTemperature values: only the myomer profile (1000/2000, BTL4.RES) is confirmed; generators are authored per-subsystem in content and could differ, which would shift where 'half-cooled' sits on the bar.
* Whether Oracle's once-seen stuck generator was crit-destroyed (authentic permanent-out), the Idle park (requires OFF/ON presses while in the yellow band), or something else — not reproducible from code reading; needs the field log for that session.
* The AudioStateWatcher bring-up guard (AUDWTHR.cpp:908-917) is assumed to PASS for GaugeAlarm54 sockets (constructed SChainOf vptr at +0x18); AUDIO_FIDELITY F8's 'all 118 state watchers bind real StateIndicators' supports this, but a per-generator [audiostate] skip line under BT_AUDIO_LOG in the FIELD build has not been ruled out this session.
* Prime-time notification (PrimeWatcher -> SendNotificationOfChange at audio-page bind if the streamed sendNotificationOnChange flag is set) delivers StateChanged(0,2) at load — whether any authored trigger misfires on that is unchecked.
########## LANE 1 ##########
## The binary's Generator state machine (issue #154 lane: BTL4OPT.EXE simulation)
### Object map (Generator, classID 0xBC1, ctor @4b225c, vtable 0x50fd74)
The generator's operational state machine is a 0x54-byte StateIndicator at gen+0x1FC (ctor `FUN_0041b9ec(this+0x1FC, 5)` = 5 levels; current level @0x210 = the "stateAlarm", previous level @0x20C) [T1]. Fields set by the ctor @4b225c: ratedVoltage@0x1D8←res+0xFC, outputVoltage@0x1DC, maxTapCount@0x1E4←res+0x100, startTime@0x1EC←res+0x104, startTimer@0x1F0, shortRecoveryTime@0x1F4←res+0x108, shortTimer@0x1F8, generatorOn@0x1D4=1, percentAvailable@0x1D0=1.0, generatorNumber@0x1E0 = last char of name − 0x40 (A=1..D=4). Initial state = SetState(2) Ready [T1]. States (2=Ready confirmed by HasVoltage @4b0b5c requiring source+0x210==2; 3=short-recovery and 1/4=off/out confirmed by the consumer-side dump @4b1224 which maps source 3→"Shorted", source 1||4→"GeneratorOff"): 0=Starting, 1=Off/Idle, 2=Ready, 3=ShortRecovery, 4=GeneratorOut.
The heat alarm is a SECOND, separate 3-level StateIndicator at gen+0x170 (level @0x184), inherited from HeatableSubsystem (ctor @4adda0: `FUN_0041b9ec(this+0x170, 3)`), with debug names @4ae050: 0="NormalHeat", 1="DegradationHeat", 2="FailureHeat" [T1].
### 1. THE THERMAL TRIP — exact write site
`GeneratorSimulation` = FUN_004b1f7c(this, dt) (part_013.c:9049-9107). Its preamble, every tick, BEFORE the state switch:
- base call FUN_004ad924 (HeatableSubsystem sim) recomputes temperature@0x114 = heatContent@0x158 / thermalMass@0x154 and drives the heat alarm with NO hysteresis: `if (T > FailureTemperature@0x11C) SetState(heatAlarm,2); else if (T > DegradationTemperature@0x118) SetState(heatAlarm,1); else SetState(heatAlarm,0)` (part_013.c:5638-5646) [T1]. The thresholds are authored content: HeatSink ctor @4adda0 loads 0x114←res+0xE4 StartingTemperature, 0x118←res+0xE8 DegradationTemperature, 0x11C←res+0xEC FailureTemperature (parse @4ae150) [T1].
- then `if (heatAlarm@0x184 == 2) SetState(genState@0x1FC, 4)` (part_013.c:9062-9064). **This is the ONLY producer of stateAlarm 4 in the binary** — I walked every SetState on the +0x1FC machine: ctor(2), ResetToInitialState @4b215c (0 then 2), toggle @4b1ed0 (0/1), sim @4b1f7c (1/4/2/2/1/0), HandleMessage msg-4 @4b21d0 (3), PoweredSubsystem-initiated short @4b11bc (3). No other site writes 4 [T1]. (The `SetState(+0x99,4)` calls in @4b0bd0/@4b0e6c are the CONSUMER PoweredSubsystem's own 5-state electrical machine @0x278 — 0=Starting,1=NoVoltage,2=Shorted,3=GeneratorOff,4=Ready per the string dump @4b1224 — do not confuse the two.)
- Also in the preamble: `if (this+0x40 == 1) SetState(genState, 1)` — pins a +0x40==1 generator to Off every tick.
- No gate on the trip: it fires at any experience level *mechanically*, but temperature can only rise when the heat model integrates (FUN_004ad7d4 gate = player+0x260, veteran+expert), so trips only occur when the heat model is on [T1].
### 2. THE RECOVERY — exact re-arm condition and threshold
Case 4 body (part_013.c:9087-9097): output forced 0 every tick; `if (heatAlarm@0x184 == 0)`: if generatorOn@0x1D4==0 → SetState(1) Off; else → startTimer@0x1F0=0, SetState(0) **Starting** — then case 0 counts startTimer up and at startTime seconds does SetState(2) Ready + `outputVoltage = (1.0 − damageZone->damageLevel) × ratedVoltage` (constant @4b2154 byte-verified = 3F800000 = 1.0f in the exe's CODE section, file offset 0xB1F54).
**The re-arm threshold is NOT "half" of anything — there is no 0.5 multiplier anywhere in the generator path** (constants adjacent to the sim: @4b2154=1.0, @4b2158=0.0, @4b2258=1.0, @4b297c=0.0 — all byte-verified from BTL4OPT.EXE) [T1]. Recovery requires the heat alarm to return to **0 (NormalHeat), i.e. T ≤ DegradationTemperature** — alarm 1 (DegradationHeat) is NOT enough; the generator stays OUT through the whole degradation band. The hysteresis is structural: trip at T > FailureTemperature, re-arm at T ≤ DegradationTemperature, plus a full StartTime spin-up before voltage returns.
**The tester's "red portion of the heat bar gone" rule matches this EXACTLY in gauge terms**: the two-part temp bars normalize to FailureTemperature with the warn boundary at DegradationTemperature (warnPix = width·Degrade/Failure, value = CurrentTemperature — gauges-hud.md §TEMP/STATUS bar, @4c4170/@4c4724) [T1]. "Red gone" ⇔ T ≤ DegradationTemperature ⇔ the binary's re-arm condition. Whether that is numerically "half-cooled" depends on authored per-mech values; field notes (open-questions.md: generators equilibrate 1100–1500 K in the degradation band vs the ~2000 FailureHeat line) put Degrade/Failure ≈ 0.55 — approximately half [T3, authored temps not extracted from the archives].
### 3. WHICH EDGE the annunciator hears
The stateAlarm machine IS a StateIndicator; SetState = FUN_0041bbd8: first line unconditionally copies current→old (+0x10←+0x14), and ONLY on an actual value change it stores the new state and synchronously fires all three watcher chains (+0x18 audio / +0x2C video / +0x40 gauge), each watcher's vtbl+0x14 (part_002.c:5510-5546) [T1]. So:
- **stateAlarm 4 is written AT TRIP** (edge old=2→new=4 fires the audio chain the same tick T crosses FailureTemperature), **re-asserted every tick while out (edge-filtered no-ops, no re-fire), and REPLACED at recovery** by the edge 4→0 (Starting), followed StartTime seconds later by 0→2 (Ready). Nothing "clears" 4 separately; no write of 4 happens at recovery.
- What SOUND plays on which edge is decided by the AUTHORED AudioStateTrigger record streamed from content, engine code AUDWTHR.cpp `AudioStateTrigger::StateChanged` [T0]: fires when `!inverseTrigger && new_state==triggerState` (ENTER edge) or `inverseTrigger && old_state==triggerState` (LEAVE edge), with optional exclude_state suppression. **Both keying modes exist in the engine.** A "Generator Out" sample keyed non-inverse on state 4 speaks at TRIP; one keyed inverse on 4 (or non-inverse on 0/2) speaks at RECOVERY. The binary/engine machinery emits both edges faithfully — if the field build speaks only at recovery, the discriminator is the authored trigger record (trigger_state / inverse_trigger / exclude_state for `Generator.GeneratorState`), which has NOT been dumped ([statecfg] via BT_ATTRBIND_LOG would capture it; no capture exists in scratchpad/docs). Note the port's GaugeAlarm54::SetLevel (heat.hpp:106) and StateIndicator layout (STATE.h: oldState@0x10/currentState@0x14) reproduce the binary semantics exactly, including the unconditional old←current copy — the port sim (powersub.cpp:1296 GeneratorSimulation) is a faithful transcription of @4b1f7c, so the mis-edged audio is NOT a divergence in the generator sim itself [T1].
### 4. "No Ready-case recompute" — CONFIRMED, with one refinement
The switch in @4b1f7c has cases 0,1,3,4 and **NO case 2** — in Ready the sim touches nothing; outputVoltage is recomputed as `(1−damage)×rated` ONLY on the two Ready-ENTRY transitions (case 0 timeout @9069-9073, case 3 timeout @9081-9085) [T1]. Refinement: `Generator::HandleMessage` @4b21d0 ALSO recomputes `(1−damage)×rated` on ANY message id ≠ 4 (gated by player+0x274 ≠ 0, not-novice), and msg 4 (short) drives SetState(3)+shortTimer=0 when +0x40 ∈ {0,2} — so a message delivery is a third recompute path, but the crit distributor delivers damage without messaging the generator, so the decomp-reference claim stands for the destroyed-in-place case [T1].
### Bonus: a binary-authentic "stuck offline forever" candidate
ToggleGeneratorOnOff @4b1ed0 (not-novice gate FUN_004ac9c8, press>0): toggling ON while the heat alarm ≠ 0 sets generatorOn=1 and startTimer=0 but deliberately does NOT SetState — it leaves the machine in whatever state it is in. If the pilot toggles a TRIPPED (state 4) generator OFF (→ state 1, generatorOn=0) and back ON while still hot (state stays 1, generatorOn=1), the machine is now in state 1 with generatorOn=1 — and case 1 has NO exit logic and NO thermal re-arm check. When the heat later cools to normal, nothing transitions: the generator stays offline indefinitely, recoverable only by another full off/on toggle pair after cooling, or by re-tripping to state 4 (whose case body honors generatorOn) [T1, pure case-walk — matches the tester's non-reproducing "stuck offline forever" one-off]. This is the same defect family as the "no Ready-case recompute" latch and the open-questions FailureHeat weapon brick (weaponAlarm 7 — a different machine, same alarm-latch pattern).
--- KEY FACTS ---
* stateAlarm 4 (GeneratorOut) has exactly ONE producer in the binary: the thermal breaker at the top of GeneratorSimulation @004b1f7c — `if (heatAlarm@0x184 == 2) SetState(genState@0x1FC, 4)` (part_013.c:9062-9064); it is written AT TRIP, held (edge-filtered) while out, and replaced 4→0→2 at recovery — no write of 4 occurs on the recovery edge [T1]
* Re-arm condition (case 4 body @004b1f7c, part_013.c:9087-9097): heat alarm must return to 0 = NormalHeat, i.e. currentTemperature ≤ DegradationTemperature (res+0xE8) — NOT half of FailureTemperature; no 0.5 constant exists in the path (sim constants @4b2154=1.0f, @4b2158=0.0f, @4b2258=1.0f byte-verified in BTL4OPT.EXE CODE section) [T1]
* Recovery is two-stage: 4→0 Starting (startTimer reset), then after StartTime (res+0x104) seconds 0→2 Ready with outputVoltage = (1.0 − damageZone->damageLevel) × ratedVoltage; if generatorOn@0x1D4==0 at cool-down it goes 4→1 Off instead [T1]
* The heat alarm producer FUN_004ad924 (part_013.c:5638-5646) has NO hysteresis: >FailureTemperature→2, >DegradationTemperature→1, else 0, every tick; thresholds loaded by HeatSink ctor @004adda0 from res+0xE4/0xE8/0xEC (StartingTemperature/DegradationTemperature/FailureTemperature, parse @004ae150); alarm names @004ae050: Normal/Degradation/FailureHeat [T1]
* The tester's era rule maps exactly: the gauge temp bars place the warn/red boundary at DegradationTemperature over a 0..FailureTemperature scale (warnPix = width·low/high, gauges-hud.md, @004c4170/@004c4724), so 'red portion gone' ⇔ T ≤ DegradationTemperature ⇔ the binary's re-arm threshold [T1]; numerically ≈0.55·Failure from field equilibrium notes (1100–1500 K degradation band vs ~2000 FailureHeat) [T3]
* The audio edge is decided by AUTHORED content, not code: engine AudioStateTrigger::StateChanged (AUDWTHR.cpp) fires on ENTER (non-inverse: new_state==triggerState) or LEAVE (inverse: old_state==triggerState) with optional exclude_state; the state machine (FUN_0041bbd8, part_002.c:5510) fires its audio/video/gauge chains synchronously on every level CHANGE, old←current copied unconditionally first [T0/T1]
* The authored AudioStateTrigger record for Generator.GeneratorState (trigger_state/inverse_trigger/exclude_state) has never been dumped — no [statecfg] capture exists in scratchpad or docs; BT_ATTRBIND_LOG would print it at load [T2 gap]
* 'No Ready-case recompute' CONFIRMED: the @004b1f7c switch has cases 0,1,3,4 and no case 2; recompute happens only on Ready-entry (case 0/3 timeouts) and on Generator::HandleMessage @004b21d0 for any message id ≠ 4 when player+0x274 ≠ 0 (not-novice); msg 4 = short → SetState(3)+shortTimer=0 when this+0x40 ∈ {0,2} [T1]
* Binary-authentic stuck-offline latch found: ToggleGeneratorOnOff @004b1ed0 turning ON while heatAlarm ≠ 0 sets generatorOn=1 WITHOUT a state transition; from state 1 (Off) there is no thermal re-arm path, so off→on toggling a hot tripped generator strands it offline after cooling until another cold toggle pair or a fresh alarm-2 trip [T1 case-walk, matches the tester's one-off]
* Generator toggle and short handling are novice-locked: FUN_004ac9c8 = (player+0x274 == 0); the heat-model integration gate is player+0x260 (veteran+expert) via FUN_004ad7d4, but the alarm thresholding runs ungated [T1]
* Consumer view for cross-checks: PoweredSubsystem sim @004b0bd0 maps source stateAlarm 3→own state 2 'Shorted', 1||4→3 'GeneratorOff', 2→restart via 0 'Starting'; own electrical state names @004b1224: 0 Starting/1 NoVoltage/2 Shorted/3 GeneratorOff/4 Ready (machine @+0x264, level @0x278 — distinct from the generator's @0x1FC/0x210) [T1]
* The port's generator machinery is a faithful transcription: powersub.cpp:1296 GeneratorSimulation mirrors @004b1f7c line-for-line, GaugeAlarm54::SetLevel (heat.hpp:106) mirrors FUN_0041bbd8 including the unconditional old←current copy, and engine StateIndicator layout (oldState@0x10/currentState@0x14) matches — the generator sim is NOT the source of the mis-edged audio [T1]
--- UNCERTAINTIES ---
* The authored trigger_state/inverse_trigger/exclude_state for the Generator.GeneratorState AudioStateTrigger (and which SF2 preset/control it drives) is undumped content data — this alone determines whether 'Generator Out' speaks at trip or recovery in an authentic build; dump with BT_ATTRBIND_LOG=1 ([statecfg]/[trigcfg] lines) on a mech load
* Whether the pod's SPOKEN 'Generator Out' warning even rides the AudioStateTrigger/SF2 path at all, versus a separate speech/annunciator system — not established in this lane
* The semantics of gen+0x40 (port name simulationState): ==1 pins the machine to Off each tick and excludes the generator from eject-counting, but what writes 1 there is unlocated; decomp-reference's 'destroyed in place keeps stale Ready voltage' implies destruction does NOT set it — the two claims need reconciling
* Actual authored Generator StartingTemperature/DegradationTemperature/FailureTemperature/StartTime values per mech are inside the compiled content archives (only the exe and L4GAUGE.CFG reference the key names as text); the ≈0.55 Degrade/Failure ratio is inferred from field equilibrium notes, not extracted values
* Whether message id 4 ('short') is ever delivered to Generator::HandleMessage in normal play (vs the @004b11bc ForceShortRecovery direct-call path) — the message's producer was not traced
* @004b2164 (Generator::DeathReset thunk cited by the port) sits in an export gap between @4b215c and @4b21d0 — shape assumed from the port comment, not read from pseudocode

stateAlarm.SetLevel(GeneratorOut); // SetLevel 4 -- called EVERY frame while FailureHeat holds
}
```
Binary: `if (param_1[0x61] == 2) FUN_0041bbd8(param_1+0x7f, 4);` (part_013.c:9062-9064) [T1 exact match].
RECOVERY (powersub.cpp:1340-1357):
```
case GeneratorOut: // 4
outputVoltage = 0.0f;
if (heatAlarm.GetLevel() == HeatSink::NormalHeat) // this+0x184 == 0
{
if (generatorOn == 0) stateAlarm.SetLevel(GeneratorIdle); // 1 -- STAYS DOWN until manual toggle
else { startTimer = 0.0f; stateAlarm.SetLevel(GeneratorStarting); } // 0 -> after StartTime secs -> SetLevel(2) Ready
}
```
Binary: `case 4: if (param_1[0x61] == 0) { if (param_1[0x75]==0) SetLevel 1; else { [0x7c]=0; SetLevel 0; } }` (part_013.c:9087-9098) [T1 exact match].
The heat thresholds are NOT in the generator — they are the HeatSink heatAlarm drive at the tail of HeatSinkSimulation, heat.cpp:851-862: `T > failureTemperature -> FailureHeat(2); else T > degradationTemperature -> DegradationHeat(1); else NormalHeat(0)`. Binary @004ad924 tail is identical (`param_1[0x47] < T -> 2; param_1[0x46] < T -> 1; else 0`, temps @0x11C/@0x118) — NO hysteresis on either side [T1]. Both temperatures are authored per-subsystem resource fields ("DegradationTemperature"/"FailureTemperature"); their generator values live in the streamed .RES model data and were not dumped here.
CONSEQUENCE FOR THE ERA RULE ("back online when the red bar portion is gone / half-cooled"): the recovery gate is heatAlarm==0, i.e. T must fall BELOW degradationTemperature — the LOWER of the two thresholds, well below the trip point. The heat gauges bind CurrentTemperature with DegradationTemperature + FailureTemperature as zone markers (content/GAUGE/L4GAUGE.CFG:4434-4436 pattern), so if the bar's red zone starts at DegradationTemperature, "red gone" == the exact recovery gate and the port is ALREADY era-correct — which matches the tester's own runs 2 and 3 ("it did come back online after cooling halfway", scratchpad/night14/housekeep14.py:224-240). This is the binary's behavior byte-for-byte; there is nothing to change in the sim [T1 code, T3 for the red-zone==degradation mapping, unverified against the palette].
== 2. Where stateAlarm is written, and on which edge ==
All stateAlarm (alarm @0x1FC, level @0x210) writers in the port:
- ctor powersub.cpp:1113 `SetLevel(GeneratorReady)` (2)
- GeneratorSimulation trip :1311 `SetLevel(4)` — TRIP edge, re-asserted every held frame
- GeneratorSimulation recovery :1346/:1354 `SetLevel(1)` or `SetLevel(0)`, then :1321 `SetLevel(2)` after StartTime — RECOVERY is TWO notify edges: 4->0, then 0->2
- ToggleGeneratorOnOff :1212/:1221 (0 on healthy re-arm, 1 on switch-off)
- ResetToInitialState :1269-1270 `SetLevel(0); SetLevel(2);` — every respawn fires a 0-then-2 notify pair (binary @004b215c does the same, part_013.c:9119-9120)
- Generator::HandleMessage msg 4 :1392 `SetLevel(GeneratorShorted)` (3)
- ForceShortRecovery (PoweredSubsystem) :555 and PowerWatcher::HandleMessage :1564 (both set 3)
- MarkGeneratorOut (powersub.hpp:483) — documented UNUSED; the destruction bridge was removed as unfounded (powersub.hpp:471-481).
The notify mechanism: GaugeAlarm54::SetLevel (heat.hpp:106) `levelB = level; if (n != level) { level = n; NotifyWatchers(); }` — oldState updated unconditionally FIRST, watchers fired ON CHANGE ONLY. Binary FUN_0041bbd8 (part_002.c:5512-5546) is semantically identical: `+0x10 = +0x14` unconditionally, then if-changed set +0x14 and Execute() every watcher on the three chains @+0x18/+0x2c/+0x40 [T1]. So the per-frame SetLevel(4) spam while tripped notifies exactly once, at the 2->4 trip edge.
THEREFORE: the port's sim DOES deliver a watcher notification on the TRIP edge (old=2, new=4), and delivers two more on recovery (4->0, 0->2). The generator sim is not the component putting the audio on the wrong edge. There is NO ForceUpdate/SetDirty/updateModel mark at either edge — grep of powersub.cpp + heat.cpp is empty, and the binary @004b1f7c contains nothing but the SetLevel calls and arithmetic; the watcher chains ARE the notification path [T1].
AUDIO WIRING (adjacent, for synthesis): GeneratorState is published as an attribute directly on stateAlarm (powersub.cpp:1051, ATTRIBUTE_ENTRY(Generator, GeneratorState, stateAlarm)); the audio renderer binds authored AudioStateTriggers to it by name (context/wintesla-port.md:94, "audiostate skips 85 -> 0"). Trigger evaluation is engine T0 (engine/MUNGA/AUDWTHR.cpp:1046-1105): non-inverse fires when new_state==triggerState, INVERSE fires when old_state==triggerState (i.e. on LEAVING the state), with optional exclude pairs. Given the sim edges above, a sound heard ONLY at recovery means the live trigger fired on 4->0 or 0->2 — i.e. either an inverse trigger on state 4 ("leaving GeneratorOut") or a trigger on entering 0/2. Which of those is authored is in the streamed audio pages, NOT in the port code — undumped. BT_ATTRBIND_LOG=1 prints every AudioStateTrigger's `[statecfg] trigState/inv/ctl/excl` at bind time (AUDWTHR.cpp:981-987), and BT_HEAT_LOG prints "[gen] X TRIPPED"/"[gen] X RESTARTING" (powersub.cpp:1308-1311, 1350-1352); one capture correlating those against the heard sample settles the edge question definitively. Related suspicion [T4]: docs/AUDIO_FIDELITY.md F5/F6 document whole blocks of authored warning audio bound to dead attributes (ReportLeak is dead on GeneratorA-D among 19 subsystems, AUDIO_FIDELITY.md:402-411) — if the pod's trip-side warning rides one of those dead bindings, the trip would be silent in the port while a different, live authored cue (e.g. a spin-up/state sound at 4->0 or 0->2) is what the tester heard at recovery and labeled "the generator out warning".
== 3. Divergence vs the context claims ==
None found. context/decomp-reference.md:470-477 ("the generator sim has NO Ready-case recompute — a generator destroyed in place keeps stale Ready voltage until any transition recomputes output") is confirmed in both the port and the binary: the GeneratorSimulation switch has cases 0/1/3/4 only, no case 2 — outputVoltage is untouched while Ready [T1]. context/subsystems.md:103-105 ("(1 − generator damage) × rated, thermal breaker on FailureHeat, no load model") matches the transcription (the `(MaxOutputVoltage - SourceLevel()) * ratedVoltage` recomputes at :1322/:1336/:1398). The gnrator.cpp/gnrator.hpp pair is an alias note only — no second class, no code emitted (gnrator.cpp:10-24). One historical note: Generator::ResetToInitialState deliberately diverges from the surviving GNRATOR.TCP source (which zeroed outputVoltage) to follow the shipped binary @004b215c (outputVoltage = ratedVoltage) — documented at powersub.cpp:1238-1263 and docs/RESPAWN_REARM_PLAN.md:116 [T1].
== 4. FailureHeat "permanent brick" family (open-questions.md:1086-1102) ==
The generator does NOT share a recompute path with the weapon FailureHeat family — only the PREDICATE. All three families gate on the identical HeatSink heatAlarm level 2 at this+0x184 (open-questions.md:644-647, disasm-verified consumers), but their latch semantics differ:
- Emitters (@004baa88): FailureHeat -> ResetFiringState + currentLevel=0 "until it cools" — SELF-RECOVERING.
- Ballistic/missile launchers (@004bbd36 / projweap gate 1): FailureHeat -> weaponAlarm 7 (NoAmmo), re-asserted unconditionally inside the machine — a LATCH released only by an EjectAmmo tap or ResetToInitialState (the reproduced 19-rounds-left brick, open-questions.md:1086-1102).
- Generator (@004b1f7c case 4): SELF-RECOVERING when heatAlarm returns to 0.
So the missile roach-motel mechanism cannot produce the tester's once-seen "stuck offline forever" generator. Port-lane candidates for that non-reproducing report, both mechanisms [T1], scenario attribution [T4]: (a) the generatorOn==0 branch — if the pilot's generator toggle (RIO 0x1A-0x1D) had put generatorOn=0 (or was pressed while tripped: the OFF branch also zeroes coolantFlowScale, powersub.cpp:1219-1225, so the tripped generator loses its own coolant flow and cools only by conduction), a cooled generator lands in Idle(1) and NEVER self-restarts — authentic binary behavior requiring a manual toggle-ON; (b) a cooling stall — recovery needs T <= degradationTemperature (far below the trip point at failureTemperature); with coolant starved the last stretch can take a very long time, reading as "never" in one sitting while the heat BAR (which may visualize a different normalization) reads "cooled".
--- KEY FACTS ---
* Port trip gate: heatAlarm==FailureHeat(2) -> stateAlarm.SetLevel(GeneratorOut=4), powersub.cpp:1304-1312, re-asserted every frame while held; byte-matches binary @004b1f7c (part_013.c:9062-9064) [T1]
* Port recovery gate: case GeneratorOut requires heatAlarm==NormalHeat(0), i.e. T <= degradationTemperature (the LOWER threshold), then 4->0 (Starting) -> after authored StartTime -> 0->2 (Ready); powersub.cpp:1340-1357 + 1316-1324; byte-matches binary part_013.c:9087-9098 [T1]
* Heat alarm thresholds have NO hysteresis: T>failureTemperature->2, T>degradationTemperature->1, else 0; heat.cpp:851-862 == binary @004ad924 tail (temps @0x118/@0x11C) [T1]
* GaugeAlarm54::SetLevel (heat.hpp:106) notifies watchers ON CHANGE ONLY, oldState updated unconditionally first — semantically identical to binary FUN_0041bbd8 (part_002.c:5512-5546); the per-frame SetLevel(4) spam produces exactly ONE trip-edge notification (old=2,new=4) [T1]
* The port sim DOES fire a watcher notification on the trip edge; a sound heard only at recovery means the bound AudioStateTrigger fired on 4->0 or 0->2 — either an authored INVERSE trigger on state 4 (fires on old_state==triggerState, engine T0 AUDWTHR.cpp:1079-1082) or a trigger on entering Starting/Ready; the authored trigger config is in the streamed audio pages, undumped [T1 mechanics, config unknown]
* No ForceUpdate/SetDirty/updateModel mark at either edge in port (grep empty over powersub.cpp+heat.cpp) or in binary @004b1f7c — the alarm watcher chains are the only notification path [T1]
* GeneratorState attribute is published directly on stateAlarm (powersub.cpp:1051); audio binding verified live ('audiostate skips 85->0', context/wintesla-port.md:94-99) [T2]
* decomp-reference.md 'no Ready-case recompute' CONFIRMED: the GeneratorSimulation switch has no case 2 in port or binary; outputVoltage stays stale while Ready [T1]; no divergence found between port and context/decomp-reference.md or context/subsystems.md generator claims
* Generator does NOT share the weapon FailureHeat recompute/latch path — only the heatAlarm==2 predicate (this+0x184). Emitters @004baa88 self-recover, ballistic/missile @004bbd36 latch weaponAlarm 7 until EjectAmmo/reset (the reproduced brick, open-questions.md:1086-1102), generator self-recovers at heatAlarm==0 [T1]
* Stuck-offline-forever candidates (mechanisms T1, attribution T4): generatorOn==0 at cool-down lands Idle(1) which never self-restarts (manual toggle required, authentic); toggling a generator OFF also zeroes its coolantFlowScale (powersub.cpp:1221-1224) starving its own cooling; recovery needs cooling all the way below degradationTemperature, far under the trip point
* ResetToInitialState fires a 0-then-2 SetLevel pair on every respawn (powersub.cpp:1269-1270 == binary @004b215c) — any audio trigger keyed on entering state 0 or 2 also fires at every respawn [T1]
* Era-rule alignment: heat gauges bind DegradationTemperature+FailureTemperature as zone markers (L4GAUGE.CFG:4434-4436 pattern); if the red zone starts at DegradationTemperature, 'red gone' == the recovery gate exactly — matching the tester's runs 2-3 recovery at half-cooled [T3]
* Diagnostics that settle the audio edge: BT_ATTRBIND_LOG=1 dumps every AudioStateTrigger's trigState/inverse/exclude at bind (AUDWTHR.cpp:981-987); BT_HEAT_LOG prints [gen] TRIPPED/RESTARTING transition lines (powersub.cpp:1308-1311,1350-1352)
--- UNCERTAINTIES ---
* The authored AudioStateTrigger configuration for GeneratorState (trigger states, inverse flags, exclude pairs, control targets) is in the streamed audio pages of the mech model resources — not dumped; this single datum decides whether the recovery-edge sound is authored (inverse/state-0 trigger, pod would behave the same) or a port parsing/eval defect. Capture with BT_ATTRBIND_LOG=1.
* Which sample the tester actually heard ('generator out warning') is unidentified — no GeneratorOut-named wav exists in audiopresets.cpp; it may be a Warnings01 klaxon split or another state cue misattributed. The trip-side warning may ride a DEAD authored binding (the AUDIO_FIDELITY F5/F6 family; ReportLeak is dead on GeneratorA-D) [T4].
* Authored DegradationTemperature/FailureTemperature values for the generators (streamed .RES resources) not extracted; the 'red zone == degradation band' heat-bar mapping is inferred from the gauge attribute bindings, not verified against the palette rendering.
* Whether the 1995 pod played the warning at the trip edge is era testimony only [T4]; nothing in the decomp examined here identifies the trip-side audio path.
* The once-seen stuck-offline generator: neither candidate (generatorOn Idle landing, cooling stall) is confirmed against the tester's session — no log was captured for that run.
########## LANE 3 ##########
## #154 Generator Out warning — KB + field-evidence lane, raw findings
### 1. What the KB already claims (inventory)
**The generator state machine (binary-grounded):**
- `stateAlarm` levels: 0=Starting, 1=Idle, 2=Ready/OnLine, 3=Shorted, 4=GeneratorOut. stateAlarm 4's producer = "the THERMAL BREAKER in GeneratorSimulation itself; a 2026-08-03 destruction→state-4 bridge was removed as unfounded" — `context/decomp-reference.md:470-477` [T1].
- "The generator sim has NO Ready-case recompute — a generator destroyed IN PLACE keeps stale Ready voltage (no bit-6 invite) until any transition (thermal trip → stateAlarm 4 GeneratorOut, short, switch-off)" — `context/decomp-reference.md:472-475` [T1, @0049c9a8 + FUN_004b1f7c].
- Offsets: `stateAlarm@0x1FC` (the 0x54 GaugeAlarm54 object base — `docs/HARD_PROBLEMS.md:251`, `docs/RESPAWN_REARM_PLAN.md:250`) vs `stateAlarm@0x210` in the eject clause (`decomp-reference.md:425`). These are CONSISTENT, not a conflict: 0x210 = 0x1FC + 0x14 = the alarm's `level` field (GaugeAlarm54 level@+0x14, `context/subsystems.md:31`). Flagging because it reads like a contradiction.
- `Generator::ResetToInitialState @004b215c` does `stateAlarm.SetLevel(0)` then `SetLevel(2)` — "a forced *change*, so watchers re-latch" — `docs/RESPAWN_REARM_PLAN.md:172` [T1]. This 0→2 double edge fires at EVERY respawn/mission start.
- Condition-flag bit table (the `[techstat]` receipts): bit0 structure≥StatusThreshold, bit1 structure>StatusFloor, bit2 CoolantLeaking, bit3 heatAlarm≠0 (Overheating), bit6 !HasVoltage (BadPower; HasVoltage = source stateAlarm==2 && |V|>ε @004b0b5c) — `decomp-reference.md:454-489` [T1]. Conditions are ROUTINE operating flags, not alarms; never read a lone SET as a latch [T2, field-verified 2026-08-08].
- Audio binding: `Generator.GeneratorState`→stateAlarm registered as a real StateIndicator; "SetLevel fires them on change"; "generator/condenser/reservoir/ammo state sounds fire on transition" — `context/wintesla-port.md:87-99` [T2]. Port-side registration: `game/reconstructed/powersub.cpp:1051` `ATTRIBUTE_ENTRY(Generator, GeneratorState, stateAlarm)` with comment "SetLevel fires audio".
- `simulationFlags` bit 0 = engine DelayWatchersFlag — "setting it permanently skips the subsystem's ExecuteWatchers (audio watchers)" — `decomp-reference.md:248-250` [T0/T1]. (A watcher-suppression footgun adjacent to this family.)
- Experience gates: "generators take damage/go offline (reroute power)" is VETERAN+; standard mode = "no generator outages", MechTech audio limited to the leg-damage warning — `context/experience-levels.md:76-81` [T1 primary source].
**What the KB does NOT contain:** any claim about WHICH state edge the "Generator Out" audio is authored on, any decode of the authored AudioStateTrigger state→note records for GeneratorState, and any claim about the recovery threshold's relation to the heat bar. The recovery threshold itself was undocumented in `context/` prose — I read it from the decomp directly (below).
### 2. Binary + authored-data ground truth (read this session)
- **`FUN_004b1f7c` (GeneratorSimulation), `reference/decomp/all/part_013.c:9053-9107` [T1]:**
- Trip: `if (heatAlarm.level==2 /*FailureHeat*/) SetLevel(stateAlarm, 4)` — runs EVERY tick while at FailureHeat; edge-firing therefore depends entirely on GaugeAlarm54::SetLevel's fire-on-change contract.
- Recovery: `case 4:` exits ONLY when `heatAlarm.level == 0` (NormalHeat): generatorOn==0 → SetLevel(1) Idle; else `startTimer=0; SetLevel(0)` Starting → spin-up `startTime` → `SetLevel(2)` Ready + voltage restore. So a tripped generator stays out through the ENTIRE FailureHeat+DegradationHeat band and returns only when T ≤ degradationTemperature.
- **Authored thresholds, raw `content/BTL4.RES` dump [T1]:** GeneratorA-D (classID 0xBC1, 0x10C records): startingTemp=77, degradationTemp=1000, failureTemp=2000 (all six mech variants identical). heatAlarm banding has NO hysteresis: >2000→2, >1000→1, else 0 (`game/reconstructed/heat.cpp:851-862`, transcribed from @004ad924).
- **Therefore the binary's recovery point is T ≤ 1000 = exactly HALF of the 2000 trip line.** Oracle's era rule ("gens return at HALF-cooled / red bar gone") is not a missing feature — it is the shipped binary's arithmetic, and the port (`powersub.cpp:1296-1372`) transcribes it faithfully. The threshold audit flagged in the handout should come back "already authentic," CONTINGENT on one unverified visual claim: that the cockpit heat bar paints its red band as the ≥degradationTemp region (gauge-coloring not audited this pass) [T3 for the bar mapping].
- **Recovery emits TWO SetLevel edges (4→0, then 0→2 after spin-up); trip emits ONE (x→4). RTIS emits the same 0→2 pair at every respawn/mission start (@004b215c, part_013.c:9119-9120).** Any audio cue keyed to entering state 0 or state 2 will sound at recovery AND at every respawn/round start; a cue keyed to entering state 4 sounds at trip. This is the structural fingerprint the wrong-edge bug must sit on [T1 for the edge structure; the authored state→sound mapping itself is UNREAD — that is the code/data lane's job].
### 3. The 1995 manual (primary source, pages read this session)
- **p23 (GENERATORS / Generator Info Center), verbatim:** "If a generator overheats, it will shut down. That generator will not come back on-line until its heat gauge has cooled down half way, which can take some time. If a generator is destroyed by a critical hit, an 'X' will appear in that generator's info center." — Oracle's era rule is PRINTED, word for word the half-way rule. Also feeds open era question #133 (the X = destroyed-by-crit, per the manual — not shutdown/overheat).
- **p14 (MECHTECH / DAMAGE CONTROL):** the warning is listed among the spoken MechTech warnings: "*Warning, coolant leak … Warning, generator out … Warning, ammo bay fire*". MechTech audio warnings + smart buttons are veteran/expert-only; standard mode gets only the leg-damage message and "you are never required to switch generators".
- **p19:** "when a generator overheats, it simply shuts down"; auto gen-mode cascade warning (all-auto + two dead gens can lock out sensors/myomers).
- **p22:** "If your 'Mech stops moving, and the heat in your myomers is OK, check the generator; it may be the system that has overheated."
- The warning is a VOICE line in 1995. **The port's SF2 banks contain no speech presets at all** (241 presets enumerated from `game/reconstructed/audiopresets.cpp`; the only warning-family presets are the `Warnings01` 8-way klaxon split and `AllWarning`). Whatever the tester hears as "Generator Out" in the port is a klaxon zone, not the spoken phrase — and where the original spoken phrases lived (not in AUDIO1/2.RES) is an unrecorded open question.
### 4. Field evidence (night15, 2026-08-10 steam logs, build 4.11.883)
- **The trip/recovery edges are FORENSICALLY INVISIBLE in field logs.** The only generator state receipts (`[gen] TRIPPED/RESTARTING`, powersub.cpp:1308-1352) are `BT_HEAT_LOG`-gated and appear 0 times in all six logs. No audio-warning receipts exist at all. #154's wrong-edge claim currently rests solely on Oracle's testimony + the manual; no log can confirm or refute it.
- **Generator Overheating (cond 3) cycling is routine and balanced** — e.g. santo/MS-FIREFLY: ~30 GeneratorX cond-3 SETs with matching CLEAREDs; acaci/ZEUS GeneratorC 5 SET/4 CLEARED (log ends mid-heat). No latch anywhere = corroborates the stuck-forever non-repro.
- **Probable real thermal trip captured (rajel/GAMERSLAB):** GeneratorB cond 3 SET :99453 (still set) → :103610-103625 ERSLaser_2 + ERPPC_2 cond 6 BadPower SET → cond 6 CLEARED :104109/:104273 → GeneratorB cond 3 CLEARED :104815 → re-SET :105025. **Note the ordering: the weapons regained voltage ~500-700 lines BEFORE the generator's Overheating flag cleared.** Under the binary model a same-generator recovery is impossible before heatAlarm→0, so this is either (a) manual/auto power rerouting to another generator (manual p14 procedure; the auto-hunt is live per `BT_POWER_DETACH_TEST` bench), or (b) an early-recovery defect. Logs cannot disambiguate (no per-weapon source receipts). Every other cond-6 cluster in the six logs traces to crit damage (gen cond 1+2 SET pairs = structure+coolant-leak flags, e.g. santo GeneratorD :107400/:107412) or to the mission-start spin-up wave (Dave :51669-52166: 11 subsystems BadPower while all gens run their startTime spin-up after load — clears in ~500 lines).
- **The respawn reset clears gen conditions wholesale** (santo :89209-89210 GeneratorA cond 1+2 CLEARED inside the `[respawn] Mech::Reset` block) — and per @004b215c each respawn replays the 0→2 stateAlarm pair. If the port's warning cue is keyed to state 0 or 2, testers should ALSO hear it at every respawn/round start — a cheap discriminating question to put to Oracle.
- **#135 adjacency receipt:** `[galarm] condition 2 code 0x80/0x87 sub 'GeneratorA/D' -> NO LAMP RESOLVED (generator=1)` — the generator-special lamp resolution path (@004cc27c power-family special) returns nothing for a leaking generator, so a generator coolant leak flashes NO annunciator. That is exactly Oracle's #135 ("coolant leak with NO flashing annunciators") signature on generators, in the current build's logs.
### 5. Prior-ticket / adjacent-defect map
- `docs/OPEN_ISSUES_FOR_TESTERS.txt:62-64` — #154 refined by Oracle: stuck-forever did NOT reproduce; era rule = half-cooled; "threshold audit due" (answer per §2: threshold already authentic).
- #133 (open era question): the MFD X — manual p23 answers it: X = destroyed by critical hit.
- The "missile spam trips FailureHeat permanent brick" (`context/open-questions.md:1086-1102`) is the WEAPON-side roach-motel: weaponAlarm 7 re-SetLevel(7) unconditionally (`decomp-reference.md:240-241`), a genuine latch. The GENERATOR breaker, by contrast, self-recovers by design. Different mechanism; only superficially the same family. If Oracle's once-seen "stuck offline forever" was real, the in-model candidates are: generatorOn==0 (state 4 → Idle requires a manual ToggleGeneratorOnOff; a pilot who punched the gen OFF while it was out stays dark forever — authentic), sustained load never letting T below 1000, or a coolant-leaked loop that can no longer shed heat at all.
- #55/RESPAWN_REARM history: `Generator::RTIS` was once transcribed with `outputVoltage = 0` (stale GNRATOR.TCP) vs the binary's `= ratedVoltage` (`docs/RESPAWN_REARM_PLAN.md:116`) — a documented past hard-brick vector, since fixed (powersub.cpp now matches @004b215c).
- git log has zero #154 commits — untouched territory.
### 6. Wrong-edge mechanism candidates (flagged for the code lane, all [T4] from this lane)
1. The authored AudioStateTrigger record for `Generator.GeneratorState` keys the warning cue at state 0 (Starting) or 2 (Ready) rather than 4 — or the port misreads the authored state value when binding.
2. The port's GaugeAlarm54 watcher passes the OLD level on change (off-by-one): a cue authored for level 4 then fires on the FIRST transition AFTER being at 4 — i.e. exactly at recovery. Symptom-exact.
3. A Start/Stop inversion on a looped alarm cue (authored: start-on-enter-4 / stop-on-exit-4).
Discriminator available without code: ask Oracle whether the same warning also sounds at respawn/round start (the RTIS 0→2 pair).
--- KEY FACTS ---
* Manual p23 verbatim: 'If a generator overheats, it will shut down. That generator will not come back on-line until its heat gauge has cooled down half way' — Oracle's era rule is printed 1995 doctrine (reference/manual/Tesla40_BT_manual.pdf p23) [T1 primary source]
* Binary recovery threshold: GeneratorSimulation @004b1f7c case 4 exits ONLY at heatAlarm==0 (NormalHeat), i.e. T <= degradationTemp (reference/decomp/all/part_013.c:9087-9097) [T1]
* Authored generator thresholds from raw BTL4.RES: startT=77, degradationTemp=1000, failureTemp=2000 for GeneratorA-D on all 6 variants — recovery at 1000 = exactly HALF the 2000 trip line, so the half-cooled rule is already the shipped arithmetic and the port transcribes it (powersub.cpp:1296-1372) [T1]
* Trip emits ONE stateAlarm edge (x->4); recovery emits TWO (4->0 Starting, then 0->2 Ready after startTime); Generator::ResetToInitialState @004b215c replays the same 0->2 pair at every respawn/mission start (part_013.c:9119-9120) [T1]
* The 'Warning, generator out' line is a spoken MechTech warning in 1995 (manual p14), veteran/expert only; the port's SF2 banks contain ZERO speech presets (241 enumerated, audiopresets.cpp) — whatever the port plays is a Warnings01 klaxon zone, and the original voice samples' home is unrecorded [T1/T2]

########## LANE 4 ##########
## ANNUNCIATOR/AUDIO LANE — how stateAlarm 4 becomes (or fails to become) the audible "Generator Out" warning
### 1. The mechanism: state audio is EDGE-FIRED from SetLevel, not polled
Chain (all verified in code + binary):
1. `Generator::stateAlarm` is a `GaugeAlarm54` (the binary's 0x54 alarm, FUN_0041b9ec) at Generator+0x1FC; it IS a StateIndicator: stateCount@+0x0c, oldState@+0x10, currentState@+0x14, three watcher SChains @+0x18/0x2c/0x40 (C:\git\bt411\game\reconstructed\heat.hpp:93-139) [T1].
2. `GaugeAlarm54::SetLevel(n)` (heat.hpp:106): `levelB = level; if (n != level) { level = n; NotifyWatchers(); }` — oldState is updated UNCONDITIONALLY, watchers fire only on a change. Byte-identical to the binary's Set_Alarm_Level @0041bbd8 (`*(p+0x10)=*(p+0x14)` unconditionally; on change, walk the three sockets calling vtbl+0x14 Execute) and to engine `StateIndicator::SetState` (C:\git\bt411\engine\MUNGA\SIMULATE.cpp:156-230) [T1/T0].
3. `AudioStateWatcher` (C:\git\bt411\engine\MUNGA\AUDWTHR.cpp:886-919) registers DIRECTLY on the alarm's +0x18 audio socket (`Cast_Object(StateIndicator*,attributePointer)->AddAudioWatcher(this)`), NOT on any Simulation's audioWatcherSocket. So subsystem-state audio is synchronous with the SetLevel edge and never passes through `Simulation::ExecuteWatchers`. The binding resolves via `ATTRIBUTE_ENTRY(Generator, GeneratorState, stateAlarm)` (C:\git\bt411\game\reconstructed\powersub.cpp:1051); field log confirms real per-generator pointers, no pad redirects (`[attrbind] class=28 subsys=[GeneratorA] attr=[GeneratorState] -> ptr=052DC844`, C:\git\bt411\content\solo_20260729.log:39445) [T2].
4. On a level change, `Execute()` (AttributeWatcherOf<StateIndicator>, C:\git\bt411\engine\MUNGA\WATCHER.h:265-327) compares its StateIndicator COPY (stateCount/oldState/currentState) to the live alarm, then `AudioStateWatcher::SendNotificationOfChange` calls `StateChanged(GetOldState(), GetState())`.
5. `AudioStateTrigger::StateChanged` (AUDWTHR.cpp:1046-1105): fires `ReceiveControl(controlID, controlValue)` when `(!inverseTrigger && new_state==triggerState) || (inverseTrigger && old_state==triggerState)` — i.e. NON-INVERSE = "on ENTERING the state"; INVERSE = "on LEAVING the state". The binary's own StateChanged @0043eb40 (part_005.c:6960-6978, member map from ctor @0043e7d4: trig@+0x80, inv@+0x84, ctlID@+0x88, ctlVal@+0x8c, excl@+0x90/+0x94) is logic-identical, and the manifest attributes audwthr.cpp/.hpp code in the image to the surviving engine source (C:\git\bt411\reference\BT410_SOURCE_MANIFEST.md, "Engine/other TUs ... source survives") [T1].
### 2. THE CORE FINDING: the wrong-edge behavior is AUTHORED IN THE SHIPPED 1995 CONTENT, not a port defect
The shipped BTL4.RES streams exactly TWO AudioStateTriggers per generator on `GeneratorState`, decoded byte-exactly from C:\git\bt411\content\BTL4.RES @0x2be9a-0x2bf2a (GeneratorB records; A/C/D identical) and confirmed by the runtime dump (solo_20260729.log:39445-39448 etc.) [T1]:
- `trigState=1 (GeneratorIdle), inverse=0, control=Start(1)/0` — fires on ENTERING Idle.
- `trigState=4 (GeneratorOut), inverse=1, control=Start(1)/0` — fires on LEAVING GeneratorOut.
There is NO trigger on entering state 4. Both triggers target the SAME non-looped warning sequence (comp=054135C0; `[seqcfg] ... looped=0 div=120 tempo=160 events=15`, notes 29/16/26 = Warnings01 zones z4/z0/z3 per C:\git\bt411\game\reconstructed\audiopresets.cpp:542-549), shared by all four generators. ControlID 1 = StartAudioControlID (C:\git\bt411\engine\MUNGA\AUDIO.h:81-95) [T1].
Cross-checked against the binary's GeneratorSimulation @004b1f7c (reference/decomp/all/part_013.c:9049-9110, matches C:\git\bt411\game\reconstructed\powersub.cpp:1296-1372 line for line) [T1]:
- THERMAL TRIP: heatAlarm==FailureHeat → `SetLevel(4)` from Ready(2) → StateChanged(2,4). Matches NO authored trigger → **the trip edge is silent, in the binary and in the port**.
- RECOVERY: state 4 + heatAlarm==NormalHeat → `SetLevel(0)` (gen on, restart) → StateChanged(4,0) fires the inverse leave-4 trigger → **the warning sequence STARTS on the recovery edge**. (If the gen was switched off: 4→1 fires BOTH triggers — leave-4 AND enter-1.)
- The when-it-DOES-play-at-"trip" cases: generator switched OFF LINE by the pilot (`ToggleGeneratorOnOff` → SetLevel(1), powersub.cpp:1221) and generator subsystem going destroyed/dead (`simulationState==1` → SetLevel(1) each tick, first transition fires) — both are enter-Idle, both play the warning at the moment of loss. Only the THERMAL breaker path (2→4) bypasses Idle and is silent until recovery.
So the port faithfully reproduces the shipped binary+content. Either the era pods really played the voice at thermal-recovery too (and the tester's memory conflates the destruction/switch-off cases, which DO play at loss), or the arcade floor ran a content revision whose GeneratorState triggers differ from this repo's BTL4.RES [T4 — cannot distinguish from the repo].
Authoring-intent evidence AGAINST the shipped config being intended: a census of ALL 118+ authored state triggers (solo_20260729.log statecfg dump) shows inverse triggers are otherwise used almost exclusively as `inv=1 ctl=2 (Stop)` loop-terminators (WeaponState 3-, 0-, AmmoState 3-leave → Stop). The generators' `inv=1 ctl=1 (Start)` rows are the ONLY subsystem-fault inverse-STARTs in the game (the sole other inverse-Start is Entity.AnimationState leave-1, a legitimate play-on-exit). A one-bit authoring slip (inverse_trigger=1 on a trigger meant as enter-4) fits the pattern; the era rule would then be restored by flipping that one authored flag in our stream/decode path — but that is a deviation from shipped content, flagged, not proposed [T1 census / T4 intent].
### 3. DelayWatchersFlag / updateModel — RULED OUT for this bug
- `AudioStateTrigger` never registers with `Simulation::AddAudioWatcher`; only `AudioTriggerOf`/`AudioMatchOf`/`AudioDeltaOf`/`AudioScaleOf` do (AUDWTHR.h:293, 770, 925, 535). `AreWatchersDelayed()` gates ONLY `Simulation::PerformAndWatch → ExecuteWatchers` (SIMULATE.cpp:459-479, mech4.cpp:8377) — the polled watchers. It CANNOT suppress one SetLevel edge and pass another; both trip and recovery notifications ride the same synchronous socket walk. [T0]
- What a stuck DelayWatchersFlag on the Generator sim WOULD kill: the two `GeneratorOn` AudioLogicalTriggers (match 1/match 0 → Start ctl1/0.5 — the polled on/off cue) and the ReportLeak matchers, silently and permanently (the projweap/mislanch `simulationFlags|=1` trap, C:\git\bt411\game\reconstructed\projweap.cpp:461,1049). Nothing in the generator path sets it — the known setters are the weapon-family bugs already fixed, plus the btplayer.cpp:622-642 diagnostic. `updateModel|=1` (ForceUpdate) is the replication dirty mark only; no bearing on watchers. [T1]
### 4. The heat bar / "red portion gone" — the recovery gate ALREADY equals red-gone
- The generator panel's temperature bar is a `VertTwoPartBar` bound (value=CurrentTemperature, low=DegradationTemperature, high=FailureTemperature) — GeneratorCluster ctor @004c746c, C:\git\bt411\game\reconstructed\btl4gau2.cpp:980-998; config `GeneratorCluster(... sgentemp.pcc, 9, 11 ...)` at C:\git\bt411\content\GAUGE\L4GAUGE.CFG:5046 [T1].
- `VertTwoPartBar::Execute` (@004c48fc, C:\git\bt411\game\reconstructed\btl4gaug.cpp:1318-1360): bar spans 0..FailureTemperature; tile bitmap below the warn line (DegradationTemperature), the FILL COLOR segment is drawn ONLY for [warnPix, valPix) — i.e. the colored ("red") portion exists exactly while CurrentTemperature > DegradationTemperature. "Red portion gone" ⇔ T ≤ DegradationTemperature [T1].
- The recovery gate is `heatAlarm.GetLevel()==NormalHeat` (powersub.cpp:1342), and heatAlarm is a pure no-hysteresis threshold ladder recomputed every HeatSinkSimulation tick: T>failure→2, T>degradation→1, else 0 (C:\git\bt411\game\reconstructed\heat.cpp:851-862, @004ad924) [T1].
- Therefore the generator leaves GeneratorOut on the EXACT tick the red portion of its bar disappears — the tester's era rule is already the implemented (and binary-authentic) threshold. The visible lag: leaving 4 enters Starting(0), voltage stays 0 for the authored StartTime spin-up before Ready(2) — so power (voltage bar/weapons) returns startTime seconds AFTER red-gone; that delay is authentic. Whether DegradationTemperature is numerically "half" of FailureTemperature is per-mech authored data in the streamed subsystem resources (not stored as text; not extracted) [T3].
- No-hysteresis corollary: a generator that keeps making heat can duty-cycle across the degradation threshold (trip→cool→restart→re-trip), playing the warning once per RECOVERY — a repeating warning that never coincides with a trip, which plausibly amplified the tester's wrong-edge perception. The "stuck offline forever" non-repro is consistent: exit requires only T ≤ degradationTemperature with the sim ticking; a true brick needs dissipation to be structurally gone (the open-questions "missile-spam FailureHeat brick" entry is about heat delivery, not this audio path).
### 5. Cross-check: alarms that DO play on their trip edge, and what differs
Nothing differs in code — one shared `AudioStateTrigger::StateChanged` serves all; the difference is purely the authored trigger rows:
- Condenser: `trigState=1 inv=0` AND `trigState=2 inv=0` → Start (ctl 1/4) — fires on ENTERING each fault state (trip edge). [T1, statecfg census]
- AmmoBin: enter-3 Start + leave-3 Stop (loop pair, cook-off countdown), enter-4 Start, enter-5 Start — trip-edge Starts, inverse used only as Stop. [T1]
- Reservoir: enter-1 Start. Weapons: enter-N Starts, inverse-Stop loop terminators. [T1]
- Generator alone has its fault state (4) authored ONLY with an inverse (leaving) Start, and its enter-Start sits on Idle(1) instead of Out(4). [T1]
--- KEY FACTS ---
* Subsystem state audio is edge-fired synchronously from GaugeAlarm54::SetLevel/StateIndicator::SetState walking the alarm's own +0x18 audio socket (heat.hpp:106, heat.cpp:96-111, SIMULATE.cpp:156-230, binary @0041bbd8) — it never passes through Simulation::ExecuteWatchers [T1]
* AudioStateTrigger semantics: non-inverse fires on ENTERING triggerState (new_state==trig); inverse fires on LEAVING it (old_state==trig) — engine source AUDWTHR.cpp:1079-1104 [T0], byte-confirmed in the binary @0043eb40 with member map from ctor @0043e7d4 [T1]
* Shipped BTL4.RES authors exactly two GeneratorState triggers per generator: (state 1 Idle, inv=0, Start) and (state 4 GeneratorOut, inv=1, Start) — decoded from BTL4.RES bytes @0x2be9a-0x2bf2a and matching the runtime [statecfg] dump (content/solo_20260729.log:39445-39448); there is NO trigger on entering state 4 [T1]
* Thermal trip (heatAlarm==FailureHeat -> SetLevel(4), Ready 2->4, @004b1f7c == powersub.cpp:1304-1312) matches no authored trigger -> trip edge is SILENT in both the port and the 1995 binary; recovery (4->0 or 4->1) fires the inverse leave-4 Start -> the reported wrong-edge behavior is the shipped content+engine behavior, not a port defect [T1]
* The warning plays at the moment of LOSS only for the enter-Idle paths: pilot switch-off (SetLevel(1), powersub.cpp:1221) and subsystem-dead simulationState==1 (powersub.cpp:1302) [T1]
* Both generator triggers on all four generators target one shared non-looped sequence (notes 29/16/26 = Warnings01 zones z4/z0/z3, audiopresets.cpp:542-549); controlID 1 = StartAudioControlID (AUDIO.h:83) [T1]
* DelayWatchersFlag (simulationFlags bit 0) gates only polled watchers (ExecuteWatchers, SIMULATE.cpp:472-474); it cannot suppress one SetLevel edge and pass another; on a generator it would instead silently kill the polled GeneratorOn on/off matchers [T0/T1]
* Authoring census: inverse triggers elsewhere are almost exclusively inv=1+Stop loop terminators; the generators' inv=1+Start on a fault state is unique among subsystem alarms — consistent with a one-flag authoring slip in the 1995 content [T1 census, T4 intent]
* Generator heat bar (VertTwoPartBar @004c48fc, btl4gau2.cpp:980-998): colored fill exists only while CurrentTemperature > DegradationTemperature, so 'red portion gone' == T <= DegradationTemperature == exactly the existing recovery gate (heatAlarm NormalHeat, heat.cpp:851-862, no hysteresis) — the tester's era rule for the return threshold is already implemented; only the authored StartTime spin-up delays visible power return [T1]
* heatAlarm has no hysteresis, so a heat-producing generator can duty-cycle trip/restart, replaying the warning once per RECOVERY [T1]
--- UNCERTAINTIES ---
* Whether the arcade-floor pods ran a content revision whose GeneratorState audio triggers differ from this repo's BTL4.RES — the era-rule claim (voice at thermal trip) contradicts the shipped authoring we have; cannot be settled from the repo [T4]
* Sample identity of Warnings01 zones z4/z0/z3 (notes 29/16/26) — assumed to be the audible 'Generator Out' voice/klaxon material; not verified by listening [T3]
* Authored DegradationTemperature/FailureTemperature values per mech (whether 'red gone' is numerically HALF-cooled) — baked into streamed subsystem resources, not extracted [T3]
* Replicant-side behavior (whether a passenger/other pod hears the warning on the same edges) — out of this lane, untraced
* No field log with BT_HEAT_LOG active captures an actual trip/recovery temperature pair, so the duty-cycle amplification of the wrong-edge perception is mechanism-derived, not field-observed [T3]

## Phase 2 — adversarial verification (two skeptic lanes)
#### VERIFIER 0 ####
ADVERSARIAL VERIFICATION OF #154 "two triggers, no enter-4" — ATTACK FAILED ON THE DECODE; PARTIAL HIT ON THE BEHAVIORAL CLAIM.
== 1. Read order: source vs binary vs port — NO DIVERGENCE [T1] ==
T0 source (engine/MUNGA/AUDWTHR.cpp:974-979): AudioStateTrigger ctor reads triggerState, inverseTrigger, controlID, controlValue, excludeTransition, excludeState, after the base chain reads subsystem CString, attribute CString, sendNotificationOnChange (WATCHER.cpp:60,91,145), dump_value (WATCHER.h:212), audio_component ObjectID (AUDWTHR.h:151). All ints/enums are 4 bytes (STYLE.H:132,137; AUDIO.h:98 AudioControlValue=Scalar float); CString = len(4)+bytes+NUL (CSTR.cpp:353-356).
Binary: ctor @0043e7d4 reads six consecutive 4-byte fields into +0x80..+0x94 after base @0043e738. Field MEANINGS (not just positions) are pinned by StateChanged @0043eb40: +0x80 is the state comparand, +0x84 the inverse boolean (selects old-vs-new comparison), +0x88/+0x8c go to ReceiveControl, +0x90/+0x94 the exclude pair, with the exclude-clause structure exactly mirroring the source. Writer @0043e8a4 emits name-list keys in the same order (trigger_state, inverse_trigger, control_ID, control_value, exclude_state).
The one attack surface the prior analysis never checked — the CALLER's argument order — also holds: SendNotificationOfChange @0043e79c passes (watcher+0x30, watcher+0x34); the snapshot filler @0041bb88 copies indicator +0x0c/+0x10/+0x14 = stateCount/oldState/currentState, so arg1=oldState, arg2=newState, matching the source. Had the caller passed (new,old), the inverse trigger WOULD have fired on enter-4 (audible trip) — this was the only single-fault reinterpretation that could rescue the testers' expectation, and it is excluded by the binary's own code.
== 2. Independent byte re-decode (my parser, from the exe-verified layout, not the port's) ==
Record A @0x02be8f: classID=0x1c, objID=0x033b @0x2be93, "GeneratorB" (len@0x2be97), "GeneratorState" (len@0x2bea6), sendNotif=1 @0x2beb9, dump=0 @0x2bebd, comp objID=0x032f @0x2bec1; trigger fields @0x2bec5: trigState=1 @0x2bec5, inverse=0 @0x2bec9, controlID=1(Start) @0x2becd, controlValue=0.0 @0x2bed1, exclTrans=0 @0x2bed5, exclState=0 @0x2bed9.
Record B @0x02bedd: objID=0x033c, same strings, comp=0x032f; fields @0x2bf13: trigState=4 @0x2bf13, inverse=1 @0x2bf17, controlID=1(Start) @0x2bf1b, controlValue=0.0 @0x2bf1f, exclTrans=0 @0x2bf23, exclState=0 @0x2bf27 (record ends 0x2bf2b — the prior's cited window 0x2be9a-0x2bf2a is these two records).
Structural proof of the layout: my strict parser recovered 2306 valid class-0x1c records file-wide with contiguous record chaining, sane enums, and printable strings — impossible under a shifted/swapped layout. RES-wide census: ALL 144 GeneratorState triggers (4 gens x 36 vehicle pages) are exactly the two shapes (1,inv0,Start) and (4,inv1,Start). No enter-4 anywhere, no Stop, no exclude. The prior analysis's decode is CORRECT.
== 3. State numbering — 0-based, verified against the binary sim and LIVE receipts ==
The binary's generator sim FUN_004b1f7c writes raw levels through SetState @0041bbd8 with no translation: heatAlarm==2 -> SetLevel(4) (thermal breaker); switch cases 0/1/3/4; recovery from 4 -> SetLevel(0) (gen on) or SetLevel(1) (gen off). Authored trigState compares verbatim against these [T1, binary-internal, port-independent].
Calibration: AmmoState authored set {enter-0 Start (feed whir), leave-0 Stop, enter-1 Start, enter-2 Start, enter-3 Start + leave-3 Stop, enter-4 Start/1, enter-5 Start/3} maps 1:1 onto ammobin.hpp levels 0=Feeding..5=Dumped; LIVE receipts in content/genedge.log: edge 0->3 fired enter-3 Start, edge 3->2 fired leave-3 Stop AND enter-2 Start — inverse semantics and 0-based numbering confirmed live. Condenser: authored enter-1/enter-2 Start/4 matches sim writes 1(degraded)/2(severe)/0(normal) (heatfamily_reslice.cpp:1443-1445).
CORRECTION to the prior analysis: its "AmmoBin cook-off enter-3/leave-3" label is WRONG — AmmoState 3 is EJECTING (eject-hold countdown loop); the cook-off warning is gated on FireCountdownStarted match watchers (ammobin.hpp:104-134). The calibration still works; the label must be fixed.
If authored trigState were 1-based: (1,inv0)->enter-Starting(0), (4,inv1)->leave-Shorted(3) — STILL no enter-4. Swapped trig/inverse fields on record B (payload 4,1) -> fire-on-leaving-state-1 — still no enter-4, and it would garble hundreds of other records (AnimationState trig=23 would become inverse=23). The ONLY reinterpretation putting a Start on ENTER GeneratorOut(4) is flipping the inverse semantics (inv=1 = fire on new==trig), excluded at T1 by @0043eb40 + @0043e79c/@0041bb88 and by the live AmmoState receipts (flipped semantics would start the eject loop on RELEASE).
== 4. VERDICT: the decode is SOLID [T1]; the behavioral conclusion is UNDER-EVIDENCED ==
The two-trigger/no-enter-4 authoring is now confirmed by three mutually independent routes (T0 source, binary pseudocode semantics, my own byte decode) plus a live semantics calibration. It is not a parser echo chamber anymore.
HOWEVER, two things keep the prior CONCLUSION short of certain, and give the testers room to be right:
(a) The live trip observation NEVER HAPPENED: content/genedge.log (the #154 bench, run 2026-08-11 06:30) contains ZERO [gen] TRIPPED/RESTARTING lines and zero GeneratorState 2->4 or 4->x [audioedge] edges — the BT_GEN_HEAT injection did not take effect (bench's own verdict: INCONCLUSIVE). "Warning plays on recovery" in the port is still a static prediction. The only generator edges captured live are 0->2 power-ups, which correctly fire nothing.
(b) "Silent by authoring" does not mean "testers hear a consistent nothing at trip": the recovery paths are asymmetric (4->0 fires ONE Start; 4->1 fires TWO Starts — leave-4 AND enter-1 — on the SAME component 0x32f), the GeneratorOn logical match watchers fire Start/0.5 on BOTH edges ([matchcfg] receipts), the 38-watcher ReportLeak warning family is known-dead (AUDIO_FIDELITY.md F6), and genedge.log shows a real delivery quirk: old=3 new=3 same-state deliveries fired BOTH the Start and the Stop of one loop (root: SetState/SetLevel writes oldState unconditionally even on no-change — binary @0041bbd8:5520 does the same, and the polling compare @0041bba8 includes oldState — so it may be authentic, but the port's polling cadence vs the binary's is unverified). Any of these is a credible source of "wrong AND inconsistent" without the RES decode being wrong.
To call it certain: re-run scratchpad/night15/gen_edge_bench.sh with the heat injection actually reaching the sim (verify the BT_GEN_HEAT gate: generatorNumber==1 && viewpoint entity; confirm the EGG's vehicle carries GeneratorA) and capture trip-edge no-fire + recovery-edge FIRED; identify what sample/sequence audio component 0x32f actually plays (warning klaxon vs generator spin-up whine — decides whether the authored intent was ever a "warning" at all); ideally, one original-cab/emulator recording of a thermal trip as behavioral ground truth.
KEY FACTS:
* Read order identical across T0 source (AUDWTHR.cpp:974-979), binary ctor @0043e7d4 (+0x80..+0x94), and the port; field meanings pinned semantically by @0043eb40 (StateChanged) and the writer @0043e8a4
* Caller argument order verified: @0043e79c passes (oldState,newState) — snapshot filled by @0041bb88 from indicator +0x10/+0x14; a swapped order was the only decode fault that could make the trip audible, and it is excluded
* Independent re-decode of BTL4.RES @0x2be8f/@0x2bedd: (trigState=1,inv=0,Start) and (trigState=4,inv=1,Start) on GeneratorB.GeneratorState, comp 0x32f — matches the prior analysis exactly; all field offsets stated (fields @0x2bec5 and @0x2bf13)
* RES-wide census (my parser, 2306 class-0x1c records): all 144 GeneratorState triggers are the same two shapes; no enter-4 trigger exists anywhere in the file
* State numbering is 0-based and raw: binary sim FUN_004b1f7c writes SetLevel 0/1/2/3/4 with 4=thermal breaker; recovery 4->0 (gen on) or 4->1 (gen off); no translation layer anywhere
* Live calibration receipts (content/genedge.log): AmmoState 0->3 fired enter-3 Start, 3->2 fired leave-3 Stop + enter-2 Start — inverse semantics and numbering confirmed at runtime
* PRIOR-ANALYSIS ERROR FOUND: AmmoState level 3 is Ejecting (eject-hold countdown), NOT cook-off; the cook-off klaxon is gated on FireCountdownStarted match watchers (ammobin.hpp:104-134)
* The #154 live bench never observed a trip: genedge.log (2026-08-11) has 0 TRIPPED/RESTARTING lines and no 2->4/4->x edges — BT_GEN_HEAT injection did not take effect; 'recovery fires the warning' is still static-only for the port
* Candidate explanations for 'inconsistent' tester reports that do NOT require a decode error: asymmetric recovery (4->1 double-Start vs 4->0 single), GeneratorOn match watchers firing Start on both edges, dead ReportLeak warning family (AUDIO_FIDELITY.md F6), and live same-state deliveries (old=3 new=3) firing Start+Stop pairs due to the unconditional oldState write in SetState (@0041bbd8, mirrored by port GaugeAlarm54::SetLevel)
UNCERTAINTIES:
* Whether the port's recovery edge actually fires the sequence live (T2 missing): the gen_edge_bench must be re-run with BT_GEN_HEAT actually reaching GeneratorSimulation (the 2026-08-11 run shows zero [gen] lines — injection gate or vehicle/generator naming issue)
* What audio component 0x32f (runtime 054135C0) actually plays — a warning sequence or the generator spin-up/idle sound; this decides whether 'warning plays on recovery' is even the right characterization of the authored intent
* Whether the same-state (old==new) Start+Stop double-delivery seen live is authentic 1995 behavior at the same frequency — the binary has the identical unconditional oldState write and snapshot compare, but the port's polling cadence vs the binary's notify path is unverified
* Whether the 1995 cab sounded anything else at thermal trip via non-AudioStateTrigger paths (heat-alarm audio, gauge alarm streams, cockpit MFD alerts) — outside this decode's scope but inside the testers' perception
* GeneratorState level-name labels (0=Starting,1=Idle) are best-effort [T3] per powersub.hpp — the numbering is certain, the English names are not
#### VERIFIER 1 ####
VERDICT: The prior analysis's AUTHORING DECODE SURVIVES verification, but its CONCLUSION ("thermal trip silent, warning on recovery, therefore behavior is consistent-by-authoring") is REFUTED on three grounds: (1) it was never runtime-verified — the #154 bench (scratchpad/night15/gen_edge_bench.sh -> content/genedge.log) contains ZERO "[gen] TRIPPED"/"RESTARTING" receipts, so no trip or recovery edge was ever observed live; the recovery-edge claim is code-derived [T1], not [T2]; (2) the enter-Idle trigger makes the SAME 3-tone sequence fire on at least five different game events with opposite meanings, four of them not mentioned by the prior analysis; (3) three field-measured port mechanisms make even correctly-fired warnings intermittent.
== 1. THE COMPLETE EVENT->SOUND TABLE (generator warning sequence = AudioControlSequence, 3 notes 29/16/26 = Warnings01_z4(loop)/z0/z3, ~3.25 s at div=120 tempo=160; ONE sequence component SHARED by all four generators A-D — solo_20260729.log:39452-39476, all four statecfg rows target comp 054135C0) ==
Authored triggers per generator (verified in both logs, excl=0/0 so NO exclude-transition clause): T-A trigState=1 inv=0 ctl=Start/0 (fires on ANY entry to state 1) and T-B trigState=4 inv=1 ctl=Start/0 (fires on ANY exit from state 4). GeneratorState enum [T1, powersub.hpp:377-388]: 0=Starting 1=Idle 2=Ready 3=Shorted 4=Out.
- Mission start / ResetToInitialState (SetLevel(0);SetLevel(2), powersub.cpp:1269-1270): edges (x,0),(0,2) -> SILENT (bench-confirmed: 4x "old=0 new=2 ... no-fire" in genedge.log).
- THERMAL TRIP 2->4 (powersub.cpp:1341, per-frame while heatAlarm==FailureHeat): SILENT. Prior analysis correct on this edge. But outputVoltage collapses -> !HasVoltage status bit (stateAlarm==4 read, powersub.cpp:1836) -> masterAlarm/MechTech + gotoEngineering gauge invite CAN sound at trip [T3 — masterAlarm edges are live in the bench log but the specific generator condition->voice line was not traced]. Testers hearing a VOICE at trip and the TONE 10-60 s later at recovery = "timing feels wrong".
- THERMAL RECOVERY 4->0 (generatorOn==1, powersub.cpp:1384): T-B FIRES — warning tone announces power RETURNING. One tone per generator recovery; four generators trip/recover STAGGERED, and each Start on the shared sequence STOPS and RESTARTS it from t=0 (AUDSEQ.cpp:409-412 StartSequence stops-if-running; StopSequence chases pending Stops, cutting the current note) -> stuttered/truncated warnings whose count varies with heat spread. A player riding the heat edge gets a periodic tone on EVERY trip/recover duty cycle — always at the recovery, never at the loss.
- RECOVERY WHILE SWITCHED OFF 4->1 (powersub.cpp:1376): BOTH T-A and T-B fire — double Start same frame (second restarts the sequence).
- PILOT TOGGLES GENERATOR OFF (ToggleGeneratorOnOff, powersub.cpp:1221, byte-matched to @004b1ed0): x->1, T-A FIRES — the "generator out" warning plays for a deliberate heat-management action (authentic, but a tester counts it as spurious). Toggle ON: SetLevel(0) only if heat healthy — silent; if heat-degraded, NO state write at all (silent, state stays at fault).
- GENERATOR CRIT-DEATH: no direct SetLevel on the crit path (BTGeneratorMarkOut has ZERO callers — the powersub.cpp:483 method is documentation-only; hpp:471 says the ForceCriticalFailure bridge was removed), BUT GeneratorSimulation's pin `if (simulationState==1) SetLevel(GeneratorIdle)` (powersub.cpp:1330-1332, authentic @004b1f7c) fires T-A on the next tick: 2->1 (or 4->1 = DOUBLE fire if it died tripped). So a generator LOSS by crit DOES play the warning — one frame late — directly contradicting "loss is silent by authoring".
- SHORT 2->3 and short-recovery 3->2 (powersub.cpp:1422,1365): SILENT both ways.
- RESPAWN WITH A TRIPPED GENERATOR: ResetToInitialState SetLevel(0) delivers (4,0) -> T-B FIRES the warning right at respawn; dying un-tripped respawns silent. Inconsistent respawn audio depending on how you died. [T1 code-read, unbenched]
- GeneratorOn POLLED MATCHERS (AudioLogicalTrigger, solo log: match=1 -> ctl1(Start)/0.5 and match=0 -> ctl1(Start)/0.5, per generator): generatorOn is init 1 and written ONLY by the toggle (powersub.cpp:1214,1222) and reset (=1). Thermal trip does NOT touch it. So: bind-time prime fires the match=1 Start (spawn hum — every AudioMatchOf subclass ctor calls PrimeWatcher, and AudioMatchOf::SendNotificationOfChange has no edge memory: it fires whenever notified AND equal, AUDWTHR.h:818-848); manual OFF fires the match=0 Start (a second sound stacked on the T-A warning). Target components unidentified (matchcfg does not print comp) — [T4 what they sound like].
== 2. INTERMITTENCY MECHANISMS (the "inconsistent" the testers report) ==
A. VOICE STEAL / TRUE DROP AT COMBAT PEAK [T2, field-measured]: L4AUDRND.cpp:1287-1409 — on channel exhaustion the incoming Start steals only from LOWER-weight running sources (transient victims are STOPPED mid-play, sustained SUSPENDED); if nothing outranks, the Start is genuinely dropped (gBTAudioTrueDrops). The 2026-08-10 field logs show up to 932 steals and 22-30 acquire-failure prints per session (scratchpad/night15/steam_20260810_f_eleng_ALIA.log). Heat trips correlate exactly with peak firefight + heat klaxon + MechTech voices, so the 3-note warning's Starts land in the most contended window: any of its three notes can be stolen mid-sequence or dropped. AUDIO_FIDELITY.md F3 adds that steal/cull/ducking are DISTANCE-BLIND in the port (AL linear model), further randomizing which source loses.
B. TRANSIENT-START VOLUME CULL: AUDREND.cpp:236-251 silently discards any Start on a transient source whose volume scale < LowAudioVolumeThreshold (0.3), and AUDREND.cpp:175-193 discards Starts on clipped transient sources entirely. Whether the cockpit warning target (seq tgt comp) is transient was not determined [T4]; if it is, this is a second silent-drop gate.
C. BIND-TIME PRIME FIRES TRIGGERS [T2, bench-observed]: AudioStateTrigger ctor calls PrimeWatcher() (AUDWTHR.cpp:989) -> GrabCurrentValue -> StateChanged(alarm.oldState, alarm.currentState) at bind. Combined with the GaugeAlarm54::SetLevel oldState-clobber (heat.hpp:106 — `levelB = level` runs even when the level does NOT change, so any state that is re-set per frame reads old==new), a trigger bound while its alarm sits AT trigState fires BOTH polarities immediately: genedge.log lines 878/881 show "[audioedge] old=3 new=3 trig=3 inv=0 ... FIRED" AND "inv=1 ... FIRED" during a mid-run mech build. For generators this is benign at normal spawn (state 2) but fires the warning on any bind/rebuild that catches state 1 or 4.
D. THE T3 BRING-UP GUARD CAN SILENTLY UNPLUG A GENERATOR'S STATE AUDIO: AUDWTHR.cpp:893-917 skips AddAudioWatcher when the bound alarm's +0x18 socket reads 0/0xCDCDCDCD — permanently silent for that subsystem, logged only under BT_AUDIO_LOG. GeneratorState binds with vtbl=00000000 (raw GaugeAlarm54 header) in every log; registration currently succeeds (edges were delivered in the bench), but the guard makes generator audio construction-order-dependent — a latent per-mech/per-build inconsistency [T3].
E. DelayWatchersFlag: gates ONLY the polled watchers (Simulation::Simulate, SIMULATE.cpp:472; mech4.cpp:8377) — i.e. the GeneratorOn/ReportLeak matchers — NOT the state triggers (those are called directly from the alarm's NotifyWatchers, heat.cpp:96-111). RequestEncore sets it (SIMULATE.cpp:727) and only the encore path clears it (UPDATE.cpp:213-215). The historical bug (death path setting bit 0, permanently muting a player's polled audio) is fixed and canary-guarded (btplayer.cpp:635-643). No current generator-warning exposure, but a regression would kill the GeneratorOn sounds while leaving the state warning alive — a plausible past contributor to "inconsistent" reports depending on build vintage.
== 3. CROSS-POD / REPLICANT ==
Replicant mechs DO build audio objects (interest teardown destroys them — context/multiplayer.md interest-teardown crash section [T2]), and subsystems DO tick on replicants when executable (#148 instance branch, mech4.cpp:8077-8104). Whether a replicant's Generator ever reaches state 1/4 locally depends on whether heat state feeds its sim — per-subsystem heat is not replicated (damage is master-side only per the #45 note), so remote generator warnings should not track the remote pilot's actual thermal state [T3]. Remote sources are also subject to the clip/volume gates, so at typical ranges they are inaudible. An observer/passenger riding a REPLICANT viewpoint would NOT hear that mech's authentic generator warnings (its master simulates elsewhere) [T3].
== 4. WHAT SURVIVES OF THE PRIOR ANALYSIS ==
The RES decode itself is confirmed at runtime: exactly two AudioStateTriggers per generator, trigState=1/inv=0/Start and trigState=4/inv=1/Start, excl=0/0, both targeting the shared 3-note sequence (solo_20260729.log:39445+ and genedge.log both match). "The trip edge 2->4 fires nothing" is true [T1]. Everything downstream of that — "therefore silent-by-authoring at loss, warning on recovery, consistent" — is refuted: crit-loss sounds (via the sim-state pin), manual OFF sounds, respawn-after-tripped sounds, recoveries stutter-restart a shared sequence, and the delivery/rendering pipeline drops or truncates the sound under exactly the conditions in which trips happen. RECOMMENDED NEXT STEP: re-run gen_edge_bench (it never tripped — zero [gen] receipts; verify the BT_GEN_HEAT injection actually reaches the viewpoint Generator A and the build contains the injection block), and add a crit-death + toggle + respawn leg to capture the T-A firings live.
KEY FACTS:
* The #154 bench log content/genedge.log contains ZERO '[gen] TRIPPED' or 'RESTARTING' receipts — the thermal trip/recovery edge mapping was NEVER observed live; the prior conclusion is code-derived [T1], not runtime-verified
* All four generators (A-D) share ONE warning sequence component (statecfg comp=054135C0 in solo_20260729.log:39452-39476); AudioControlSequence::StartSequence stops-and-restarts if already running (AUDSEQ.cpp:409-412), so staggered per-generator recoveries stutter/truncate the warning
* GeneratorState enum: 0=Starting 1=Idle 2=Ready 3=Shorted 4=Out (powersub.hpp:377-388); authored triggers: enter-1 Start and leave-4 Start, no exclude clauses (excl=0/0)
* The enter-Idle trigger fires the SAME warning on: generator crit-death (simulationState==1 pin, powersub.cpp:1330-1332), pilot toggling a generator OFF (powersub.cpp:1221), and recovery-while-off 4->1 (double-fire with the inverse trigger)
* ResetToInitialState does SetLevel(0);SetLevel(2) (powersub.cpp:1269-1270): a mech that died with a tripped generator (state 4) fires the warning AT RESPAWN via the 4->0 edge; dying un-tripped respawns silent
* GaugeAlarm54::SetLevel (heat.hpp:106) clobbers oldState unconditionally (levelB=level even when unchanged) and notifies only on change; per-frame same-level SetLevel therefore makes old==new at the alarm
* Every concrete audio trigger ctor calls PrimeWatcher() at bind, which delivers StateChanged(old,cur) unconditionally; bench lines show old==new deliveries that FIRED both trigger polarities (genedge.log '[audioedge] old=3 new=3 trig=3 ... FIRED' for inv=0 AND inv=1) — a trigger bound while its alarm sits at trigState fires spuriously
* Voice contention is live in current builds: 2026-08-10 field logs show up to 932 voice steals and 22-30 acquire failures per session (scratchpad/night15/steam_20260810_f_eleng_ALIA.log); the steal loop stops transient victims mid-play and true-drops unrankable Starts (L4AUDRND.cpp:1287-1409)
* Transient Starts are silently discarded when clipped or below LowAudioVolumeThreshold=0.3 (AUDREND.cpp:175-251), and the cull is distance-blind (AUDIO_FIDELITY.md F3)
* The AudioStateWatcher bring-up guard (AUDWTHR.cpp:893-917) silently skips watcher registration on an unconstructed alarm socket — construction-order-dependent permanent silence for that subsystem's state audio [T3 latent]
* DelayWatchersFlag gates only POLLED watchers (GeneratorOn/ReportLeak matchers), never the alarm-socket state triggers; the historical death-path bit-0 bug is fixed and canary-guarded (btplayer.cpp:635-643)
* GeneratorOn is written ONLY by the pilot toggle and reset — a thermal trip does NOT clear it; its two matchers both issue Start (ctl1/0.5): match=1 at bind/toggle-ON, match=0 at toggle-OFF
* BTGeneratorMarkOut has zero call sites — generator crit-death does NOT SetLevel(4); the warning at crit-death comes from the simulationState==1 Idle pin one tick later
* Thermal trip zeroes outputVoltage -> !HasVoltage status bit (stateAlarm==4, powersub.cpp:1836) -> masterAlarm/MechTech + gotoEngineering invite can sound AT TRIP while the tone sequence sounds at RECOVERY — a perception split for testers
UNCERTAINTIES:
* Why the bench never tripped: BT_GEN_HEAT=50000 for 25 s should exceed FailureTemperature — either the injection block wasn't in the running build, the viewpoint-entity/generatorNumber gate didn't match, or the run window missed; needs a re-run before ANY edge claim is called verified
* Whether the warning sequence's target source (tgt comp, e.g. 0540FA18) is TransientAudioRenderType — determines exposure to the volume-cull and clip drop gates (AUDREND.cpp:175-251)
* The exact source of the REPEATED old==new deliveries to the same comps in genedge.log (lines 814/978/1030): interpreted as bind-time primes of successive identical weapons sharing sequence comps during a mid-run mech build; not traced to completion — an unidentified re-prime/re-execute path would widen mechanism C to mid-life spurious warnings (including old=4,new=4 firing the warning DURING a trip)
* What the GeneratorOn matchers' Starts (ctl1/0.5) actually sound like — [matchcfg] does not print the target component; needs a matchfire capture or RES decode of those pages
* Whether a MechTech VOICE line specifically fires on the generator !HasVoltage condition at trip time in the port (masterAlarm is live, but the condition->voice mapping for generator-out was not traced) [T3]
* Whether replicant Generator subsystems ever reach state 1/4 in MP (per-subsystem heat is believed master-side only) and whether their warning sequences route to spatialized sources or a center-channel path — the passenger/observer-seat audio experience is unaudited
* Whether destroyed generators keep ticking GeneratorSimulation long enough for the simulationState==1 pin to deliver its edge in every case (DoNothingOnce/NeverExecute latching order at subsystem death)
* Whether any encore/re-stream path rebinds audio pages mid-round (which would prime-fire triggers against in-state alarms); NotifyOfReplacementEntityCreation is Fail('under construction') so late re-creation may be impossible today

# The GHOST MECH / zombie-wreck failure — field analysis 2026-07-29
## ✅ FIXED 2026-07-30 — two defects that were masking each other
**1. The death latch never released on failure.** The binary's `FUN_004c012c` tail is
`Post(...)` → `*(this+0x290) = 0` → `*(this+0x258) = 0`. We had the `Post` and the
`suppressConsole` and were **missing the middle instruction**, so `deathPending` cleared only on
SUCCESS paths. One failed respawn latched the pilot for the rest of the mission — every later death
hit the dedup and was SWALLOWED, so the cycle could never restart. That is what made a transient
hiccup a PERMANENT ghost, and it matches the field signature exactly (8 cycles, 6 stranded, none
recovering). Fixed in `btplayer.cpp` (death-handler tail).
**2. `VehicleDeadMessage` was dispatched TWICE per death.** `BTPostKillScore` (`btplayer.cpp:2263`)
sent a second one "to credit a death" — but that message is the RESPAWN-CYCLE TRIGGER, not a
scoreboard increment, and the tally is already credited by the handler's `++deathTally` (`:538`).
Both fire inside the same death transition (`mech4.cpp:2006` and `:2110`), so they were always
paired. Removed.
**They hid each other:** the duplicate made the latch look necessary, and the latch made the
duplicate invisible — every `SWALLOWED` warning in the field logs was simply the latch deduping our
own duplicate (8 of 8 deaths, a 100 % base rate, which is why it correlated with nothing). Fixing
either alone makes things visibly worse, which is why earlier passes at #57/#55 kept adding
clear-sites instead of finding the root. The binary broke the tie.
**Verified (4-node stress, 2026-07-30):** four simultaneous networked nodes, all dying every ~35 s
on staggered timers so respawn handshakes overlap (the field condition): **56 death cycles, every
completed one `START`→`RESET`, 0 swallowed / 0 mismatch / 0 discarded / 0 ghost / 0 crash** across
all four. Scoreboard: every node's `PLAYER_DEAD` matchlog rows show `deaths=N tally=N` in lockstep,
one increment per death (13/13/15/15) — the DEATHS column the comms panel draws is exact; the
kill-credit path evaluated all 56 deaths and correctly declined each self-kill (`NOCREDIT self=1`),
KILLS untouched by the fix (separate `ScoreMessage` path). Bench: `scratchpad/night6/mp4_stress.sh`
+ `content/MP4.EGG`.
**Two observations from watching the 4-node run, both run down (2026-07-30):** (1) *"comms panel
counted no deaths"* — the panel machinery is CORRECT (2-node rerun with a draw-value probe: both
rows on both nodes drew 0→9/0→11 live, local + replicated); the 4-node zeros were the artificial
load (4 core-pinned instances → PilotList Execute starved to <0.6 Hz, panel minutes-stale). Probe
stays in (`[score] panel DRAW`, BT_SCORE_LOG). (2) *"a respawn had no blue vortex"* — REAL and now
fixed: the warp effect is one global slot and a PEER's un-wreck sphere (`BTStartWarpEffect`) could
stomp the local pilot's own POV vortex mid-lifecycle; fixed by POV-priority self-skip
(btl4vid.cpp; `context/translocation-warp.md`). Pre-fix this never showed because overlapping
respawns barely existed — the ghost fix CREATED the traffic that exposed it.
**Verified:** solo **17 consecutive death/respawn cycles**, every one `START`→`RESET`, 0 swallowed /
0 mismatch / 0 crash (pre-fix this strands permanently after cycle 1). Two-node MP over a real
network path with cross-machine drop-zone replies: A 11 cycles, B 12, 0 swallowed / 0 mismatch /
0 discarded / 0 crash. Bench: `scratchpad/night6/mp_ghost.sh`, `BT_SELF_DAMAGE_REPEAT=1`.
**Status of the analysis below:** the mechanism write-up that led to the fix. The instrumentation
(`[dz]`, `[dzreq]`, `[ghost]`) stays in — it is what will prove the fix in the field, and the
cross-machine dependency in §4 is still a real fragility even with the latch fixed. Field session: 2026-07-29 night, Steam MP, 5 players, build 4.11.642. Raw logs and the
verbatim agent findings are in `scratchpad/night6/` (uncommitted — they contain machine names and
Steam identities). Tracker: #81 (zombie wreck), #57 (deathPending latch), #45 (tally replication).
## The one-sentence version
A death whose **drop-zone reply never arrives** leaves the respawn cycle stranded, so the mech is
never reset and never repainted — and because the render-side wreck swap is **one-way**, the pilot
keeps driving a burning hulk that sinks out of the world after ~18 s and then cannot be drawn at
all. The "wreckage moving and shooting" report and the "invisible ghost" report are **the same
failure at two different ages**.
## Established from the field logs [T1]
- Exactly **8 death cycles** in the whole session. Every one has the same 3-line signature at
consecutive lines: `death cycle START` → `*** DESTROYED ***` → `WARNING: death ... SWALLOWED`.
- **Only 2 of 8 reached `RESET at drop zone`.** A stranded cycle predicts ghosting **perfectly**:
8/8 cycles, 10/10 player-matches, in both directions.
- Match 2: all four non-host players died, all four stranded, zero RESETs anywhere = "everybody
ghosted". **The host did not ghost because he never died** — his log holds no death cycle at all.
(There is nothing special about being host; an earlier reading of this was wrong.)
- Match 1: three deaths, two stranded, one completed. The completion is the control case, and it is
the "self-corrected for one player" the testers reported.
- ⚠ **The SWALLOWED warning is benign.** It fires on 8 of 8 deaths, including both clean
completions and a build-641 death, so its base rate is 100% and its correlation with ghosting is
zero. It is not even a second death — it is the same death re-entering the notify from inside the
cycle. Do not treat it as a signal (an earlier reading did).
- ⚠ **Player IDs are per-match**: node = lobby token octet + 1, host always `.1`. `player 3:1` is a
different human in every match. Any cross-machine identification must decode this first.
- ⚠ An earlier "three spurious RESETs on the host" finding was an **aggregation artifact** — one
log file spans ~18 sessions and each session legitimately logs one spawn RESET.
## The render mechanism [T1, code]
- `btl4vid.cpp:1255-1300` — the wreck sink is a **pure timer**, nothing about movement: 0.25 s
reveal, then `sink = -0.025·t²`, and at `-8.0` the hulk/debris/flames get `SetDrawObj(NULL)` plus
`[BTrender] wreck buried (sink complete)`. That threshold is reached at **t ≈ 18 s**.
- The wreck objects hang off the mech's own render tree as an offset, so **they travel with the
pilot** — hence a moving, burning, shooting wreck for the first ~18 s.
- `mech4.cpp:1827` — a healthy respawn calls `BTRebuildMechModel` on Reset precisely because "the
wreck swap is one-way on the render side". No reply → no Reset → no rebuild → the hulk sinks and
the player is invisible but still simulated and driveable.
- Peers apply the wreck swap correctly and in a bit-identical order across machines, so the ghost is
**not** an entity peers never learned about — it is an entity whose presentation is frozen dead
and then hidden.
## The stall itself [T0 WinTesla — NOT proven authentic]
`engine/MUNGA/DROPZONE.cpp`: a slot is granted only if `IsAvailable()` — busy for `DOWN_TIME = 5 s`
after use, and any other player's vehicle within 2 m marks it busy. **When no slot is free the
handler reposts the message to itself every 0.1 s at `MaxEventPriority` and never replies**, so the
requester's `deathPending` latch is never cleared.
⚠ **Provenance:** `engine/MUNGA` is **WinTesla**, the later Windows port of MUNGA taken from updated
Red Planet (which converted the Division hardware to software). **The 1995 game never ran it.** So
this behaviour is authoritative for what we compile, *not* for what the pods did. BT's own
`munga/dropzone.cpp` is **absent from the decomp export** — the 1995 assignment policy is an
unrecovered gap. Recovering it (byte-scan + windowed disasm, the technique that recovered
`FUN_004a6344`) is the open task.
## 2026-07-30 dig: the respawn handshake, walked end to end
Re-read the whole chain (death → +5 s re-post → engine hunt → DropZone grant → reply → Reset) and
**measured** the parts that were assumptions. Results, in order of importance:
**1. The engine hunt RETRIES EVERY 2 SECONDS, forever, while the mech is dead** [T0]
(`PLAYER.cpp:325-327` posts the message back to itself unconditionally; its only state-based exit is
`GetSimulationState() == DropZoneAcquiredState`, which never happens — see 3). The DropZone also has
a resend net: a repeat request from the same requester + same `deathCount` re-grants the **same**
slot even while it is busy (`DROPZONE.cpp:182-194`). **So "a transient no-slot" and "one lost reply"
are both ELIMINATED as causes** — the request keeps being re-sent and re-granted every 2 s. A
permanent strand needs a permanent reason.
**2. THE SILENT DISCARD — the one remaining unlit path, now instrumented** [T1]
`BTPlayer::DropZoneReplyMessageHandler` is `if (!playerVehicle) … else if (deathCount ==
message->deathCount) … else { return; }`. That final branch was a **bare return with no logging**:
the drop zone granted a spot and replied, the numbers disagreed, and the reply was dropped —
`deathPending` stays latched, the mech is never `Reset`, and the pilot is a permanent ghost **with
zero trace in the log**. That is exactly why 6 of 8 field cycles stranded leaving no evidence. Now
always-on (`[ghost] DROP-ZONE REPLY DISCARDED …`) and it prints the **direction** of the mismatch,
which decides the fix: `msgDeath < ours` = genuinely stale (dropping is correct); `msgDeath > ours` =
**our counter is behind and we threw away a live respawn** — which points straight at #45 (the death
tally does not replicate correctly). Deliberately NOT "recovered" yet: guessing the direction would
be a stand-in, and the wrong guess respawns a mech that is still alive.
**3. ⚠ LANDMINE — do not convert the two `Set_Alarm_Level` raw writes to `SetSimulationState()`.**
`Set_Alarm_Level` is an **empty stub** (`btstubs.cpp:87`), so the death path's
`Set_Alarm_Level(this+0x2c, 1)` and the reply path's `(this+0x2c, 2)` are **no-ops** today. Their
values decode perfectly against `Player`'s enum (`PLAYER.h:273-279`) as `DropZoneAcquiredState`(1)
and `VehicleTranslocatedState`(2) — `DropZoneAcquiredState = Entity::StateCount`, and `Entity` adds
no states, so it is **1**. That makes "obviously these should be `SetSimulationState` calls" a very
attractive and **catastrophic** fix: the engine hunt is gated on `GetSimulationState() !=
DropZoneAcquiredState`, so setting state 1 on death would stop `AssignDropZone` from ever being
dispatched and make **every** pilot ghost permanently.
Measured: our `BTPlayer::simulationState` is at **0x24**, not 0x2c, and the write leaves it at 0
(`[ghost] death raw-write(+0x2c,1): simState 0 -> 0 (hunt gate still open)`). In the binary `+0x2c`
is the **Simulation-base alarm** — the same field the mech side calls `graphicAlarm` (`@0x4ac126`:
"owner alarm+0x2C -> level 9"). Our layout models that only as a `Mech` member, so a `BTPlayer` has
nowhere to put it; the stub is harmless until we recover what reads a *Player's* alarm in the binary
(likely a cockpit/HUD respawn indicator). [T1 offsets, T3 purpose]
**4. EVERY MP RESPAWN IS A CROSS-MACHINE ROUND TRIP — and that is the single point of failure**
[T2, two-node bench `scratchpad/night6/mp_ghost.sh`]. Measured on a 2-node rig with the host:local
labels: each player's request was answered by **the OTHER machine's** DropZone.
```
mp_a.log: [dzreq] player 2:1 asking for a drop zone ... <- A's own player asks
mp_b.log: [dz] GRANTED slot 7 to 2:1 death#1 ... <- B answered it
mp_b.log: [dzreq] player 3:1 asking for a drop zone ... <- B's own player asks
mp_a.log: [dz] GRANTED slot 0 to 3:1 death#1 ... <- A answered it
```
`FindGroup("DropZones")` iterates **every** DropZone entity including replicants of remotely-mastered
ones and picks the geometrically closest, so a respawn is: *my request → an arbitrary peer's
DropZone → that peer's reply → back over the wire to me.* With five players that is five round trips
through arbitrary peers, and **one degraded peer can ghost everybody else.**
That dovetails exactly with the otherwise-unexplained field finding that **one machine stopped
processing the effect/death-transition stream 57 % into match 1 and never recovered** (0 explosions /
0 wreck swaps / 0 burials while the other four logged 4/4/4). A node in that state that owns the
closest drop zone cannot answer anyone's respawn — which is what "everybody ghosted" looks like.
It also explains why solo is 100 % reliable (the whole handshake is in-process) and why the
2-node bench passes (both nodes healthy, replies land, `deathCount` agrees).
**Revised theory of the ghost (two layers):**
- *Structural:* respawn depends on a cross-machine round trip through a peer that may be lagging,
stalled, or holding a stale view of my player. Not drop-zone starvation (`slots=8`) and not a
single lost reply (the hunt retries every 2 s forever).
- *Mechanism when the reply does arrive but is stale/mismatched:* the silent discard in 2 — the
reply's `deathCount` disagrees and it is dropped without a trace, which couples this to #45.
**Two candidate fixes, both needing the next field logs to choose between:**
(a) **Prefer a locally-mastered DropZone** when one exists, keeping the handshake in-process and
removing the remote dependency entirely — cheap and robust, but it changes which physical pad you
land on, so check it against the maps first. (b) **Make the reply path tolerant**: accept a granted
reply whose `deathCount` is *ahead* of ours (our counter is behind) instead of discarding it, and
never leave `deathPending` latched on a discard. ⚠ Neither should be guessed at blind — the
`[ghost] DROP-ZONE REPLY DISCARDED` line's mismatch direction decides it in one line of log.
## HOW THE BINARY HANDLES IT — `deathPending` is OUR INVENTION [T1, decisive]
Read BT's own respawn code (it *is* in the export, even though `munga/dropzone.cpp` is not) and
checked it against the raw binary.
**The hunt is faithful.** BT's `Player::VehicleDeadMessageHandler` = `FUN_0042db80`
(`part_003.c:12029`) gates on `message->deathCount == player->deathCount` **and**
`player+0x40 != 1` — i.e. `simulationState != DropZoneAcquiredState`, exactly WinTesla's two gates —
then runs the same closest-DropZone search skipping `"win*"` zones, dispatches `AssignDropZone`, and
**re-posts the message to itself** on a timer. So the retry loop and the cross-machine hunt are
authentic 1995 behaviour, not a WinTesla artifact.
**But the latch is not.** BT's `BTPlayer::VehicleDeadMessageHandler` = `FUN_004c012c`
(`part_013.c:10504`) ends with:
```
++deathCount; message->deathCount = deathCount; --lives;
updateModel |= 1; alarm(+0x2c, 1); save dropZoneLocation;
Post(HighPriority, self, message, Now()+delay);
*(param_1 + 0x290) = 0; // <-- the field our reconstruction calls deathPending
```
**The binary CLEARS that field at the end of every death.** Verified against `BTL4OPT.EXE` itself:
`+0x290` is written in exactly **three** places in the whole executable
(`file_off 0x0b75fb`, `0x0bffe3`, `0x0c0a05`), and **all three store a zeroed register** —
`xor ecx,ecx` / `xor eax,eax` / `xor edx,edx` immediately before. There is **no write of 1, or of
any non-zero value, to `+0x290` anywhere in the binary.** Two of the three are constructor/reset
sweeps; the middle one is the death handler above (it sits right after the `call` to `Post` and
`add esp,0x14`, matching the decompiled tail exactly).
**So in 1995 there is no death-pending gate at all.** Our `btplayer.cpp:505` does
`deathPending = 1`, and six separate sites then have to clear it (`:382 :469 :1431 :1442 :1461
:1532`) — each one a patch for a different stranding scenario. Gitea **#57 and #55 are artifacts of
that invention**, not of the original design.
**And that is what makes a ghost PERMANENT.** In BT a failed respawn is harmless: the 2-second
re-post keeps hunting, and the next death starts a clean cycle. In ours the first failure latches
the pilot — every later death hits the dedup and is SWALLOWED ("deaths so far 1" forever), so the
pilot can never recover for the rest of the mission. That is precisely the field signature: 8 death
cycles, 6 stranded, none of them ever recovering.
**Proposed fix (faithful, and it removes the whole bug class):** match the binary — clear the field
at the end of the death handler instead of latching it, and drop the dedup gate that depends on it.
⚠ Six sites currently rely on that latch's existence, and the SWALLOWED dedup is load-bearing for
the "one death, one cycle" behaviour, so this wants a deliberate two-node bench rather than a
late-night edit. Caveat on the identification: `+0x290 ↔ deathPending` rests on our own
reconstruction's mapping (our compiled `BTPlayer` is only `0x28c` bytes, so the offsets cannot
match directly) — but the *behavioural* evidence (BT's death handler clears it; nothing in the
binary ever sets it) is read straight from the executable.
## What the instrumentation already killed
`slots=8` (measured, `[dz] POOL`). An 8-slot pool **cannot** be cooldown-starved by 5 players (at
most 5 slots on cooldown at once), so the shared `dropzone=one` in `tools/eggmodel.py:42` is **not**
the bottleneck. Suspicion moves to the handshake: a lost reply, or a `deathCount` mismatch — the
engine gates the hunt on `message->deathCount == deathCount` and the DropZone's resend safety net is
keyed on `lastDeathCount == message->deathCount`, so one mismatch breaks both silently (cf. #45).
## Instrumentation shipped (`ba6756c`) — always-on, no env var needed
| line | meaning |
|---|---|
| `[dz] POOL name= slots= downTime= proximityBlock=` | once per mission: the pool size |
| `[dz] GRANTED slot N to entity E death#D waited=Xs` | one per respawn; `waited` is the headline; tags `(GHOST RECOVERED)` past 15 s |
| `[dz] STALL` / `[dz] GHOST LIKELY` | escalating, rate-limited per waiter; names **why** each slot is busy (age + last user) — this discriminates cooldown saturation from proximity blocking |
| `[dzreq] player P asking ... try=N msgDeath= ourDeathCount=` | requester half; flags `*** MISMATCH ***` |
`BT_DROPZONE_LOG=1` adds a verbose per-request slot dump for bench work.
## Next actions, in order
1. **Recover BT's 1995 drop-zone policy** from `content/BTL4OPT.EXE` (decomp gap). The key question:
when no slot was available, did BT also repost forever and never reply? If yes, the stall is
authentic and our divergence is elsewhere; if no, implement what BT did.
2. **Read the next field logs' `[dz]`/`[dzreq]` lines** — they answer cooldown-vs-proximity and
lost-reply-vs-deathCount-mismatch directly.
3. Ask the testers one question that discriminates a second defect: **did a flaming mover stay
visible for more than ~20 s?** If yes, the sink tick is not running for that entity (updater
early-return, or a render-tree rebuild resetting `wreckAge`) — a second bug on top of this one.
4. Separately filed/needed: one machine **stopped processing the effect/death-transition stream**
57 % into a match and never recovered (0 explosions / 0 wreck swaps / 0 burials while the other
four logged 4/4/4) — that machine was playing a stale world, and it is why that player reported
the whole "desync cluster".
## The desync cluster is four separate things, not one bug [T2]
- **Throttle reads zero** — local, and present in the *good* sessions too. ⚠ Unresolved nuance: the
internal `thr` field is 0 in every field `[drive]` sample while mechs moved, but reads 0.8 in solo
benches; whether that is the same thing the player saw on his gauge is **not** established.
- **No weapon audio** — local audio-source starvation caused by the **map's ambient emitters**
(`arena2_morning` ≈ 10.6 effects/s × ~2.5 voices pins the 256-source pool); thousands of
`ACQUIRE FAILED ... pool is exhausted`. Unrelated to crits or the network.
- **Weapons fire without damage** — replication staleness. The shooter resolves damage and awards
its own score locally, so a shooter always *sees* hits even when the victim applies nothing.
- **Other mechs lagging/misplaced** — the same stale-world condition as item 4 above.
## Why tonight and not before
Nothing in 642 broke multiplayer. Critical hits landing for real (first time) made deaths far more
frequent, and every death is a chance for this stall — so a rare race became a common one. Fewer
players ⇒ fewer deaths ⇒ clean matches, which is exactly what the testers observed.

# Task 5 — #150 fix archaeology + bench coverage hole
## 1. Exactly what 46ff8dd changed (the #150 fix, 2026-08-10 10:30, "4.11.87x" era)
Commit `46ff8dd262b20a08334d44338e69fc686a6c7958` touched only `game/reconstructed/mech.cpp` (+28/-1) and added `scratchpad/night14/scorepair.sh` (new, 30 lines). All changes are inside `Mech::TakeDamageMessageHandler`.
**Before (pre-fix state of the report tail):**
- The call to `BTMechPostCombatReports(this, message, damageTally, zoneDestroyed, reportZone, newly_destroyed)` ran **unconditionally** — on BOTH master and replicant instances of the victim mech (the port deliberately applies damage on replicants for local visual response, and the report tail rode along).
- The `newly_destroyed` argument was computed as `deathBlastArmed && IsMechDestroyed()` — a movement-mode-derived flag, not an entry/exit edge.
**After (the two binary-cited gates):**
1. **Master-only gate** (mech.cpp:1270 today): `if (GetInstance() != ReplicantInstance) { BTMechPostCombatReports(...); }`. Grounded in the binary's opening assertion `if ((flags & 0xc) == 4) Fail("Replicant Mech recieving takedamage", MECH.CPP, 0x3da)` [part_012.c:14613] — in 1995 the tail could only ever run on the victim's master. Local damage application on replicants stays.
2. **destroyedAtEntry latch** (mech.cpp:1039 today): `const int destroyedAtEntry = IsMechDestroyed();` sampled **at handler entry**, and the last argument became `!destroyedAtEntry && IsMechDestroyed()` — the binary's `local_14` 0->1 edge across this handler call (part_012.c:14625-14629). A later salvo of the killing volley (arriving after the mech is already destroyed) takes the inflicted-only path.
**What the latch gates vs what it does NOT gate (verified against current mech.cpp):**
- It gates **only the `newly_destroyed` argument**, i.e. block A (the type-2 KILL report to the shooter's player) inside `BTMechPostCombatReports` (btplayer.cpp, `if (newly_destroyed)` branch).
- It does **NOT** gate block B (type-0 inflicted report) or block C (type-1 received report) — post-death salvos on the master still emit those.
- It does **NOT** gate the **death_tail** at mech.cpp:1335-1343: `if (deathBlastArmed && IsMechDestroyed()) { BTMechPostVehicleDead(...); BTApplyDeathSplash(...); }` — this still uses the OLD pre-latch predicate, and **the master-only gate does not cover it either** (it sits outside the `GetInstance() != ReplicantInstance` block). `BTMechPostVehicleDead` is the dispatcher of the VehicleDead message whose `deathCount == -1` branch in `BTPlayer` does `++deathCount` / `++deathTally`, logs `PLAYER_DEAD`, and applies the -500 death cost (btplayer.cpp:582-736). **[Inference, flagged]** This ungated, un-latched VehicleDead dispatch is the natural suspect for #162's deathCount multi-increment — 46ff8dd hardened the score reports and left the death notification on the old predicate.
## 2. Other recent score/death/penalty changes in btplayer.cpp (last 3 weeks)
`git log` on `game/reconstructed/btplayer.cpp` (all within 2026-07-25 → 2026-08-08):
- **a52207d / 48d47ef (07-25, #45):** reclaimed the binary's DEATHS field (`deathTally` @+0x280) as the displayed/replicated counter, distinct from the engine's respawn-handshake `deathCount` (@+0x200, seeded -2); PLAYER_DEAD matchlog row logs BOTH (`deaths=` and `tally=`).
- **a357dc4 (07-30, #81 ghost):** released the stuck `deathPending` death latch + stopped a duplicate VehicleDead. Note: `deathPending` (btplayer.cpp:546-559) is the ONLY dedup on the death cycle — a death arriving while a cycle is pending is SWALLOWED with a warning.
- **1efe8ef (08-02, #118):** restored `SpecialCaseDeathPenalty` (role+0x20) and its consumer: every death with `advancedDamageOn` hands the ENGINE base `Player::ScoreMessageHandler` a type-1 award of `-penalty` via a **DIRECT base call** — deliberately bypassing BT dispatch, therefore **structurally invisible to the matchlog** (btplayer.cpp:726-736 today).
- **91bd286 (08-05, #45/#134):** the big one — reconstructed the authentic report tail `BTMechPostCombatReports` (blocks A/B/C @0x4a02f4-0x4a0890) + `BTMechPostVehicleDead` (@0x4a07d4); retired the bring-up producers `BTPostDamageScore`/`BTPostKillScore`. This is what moved report emission into the victim's TakeDamage handler — the code 46ff8dd later had to gate.
- **2772175 (08-07):** restored the type-0 Dispatch-override interceptor (`BTPlayer::ScoreInflictedMessageHandler` @004c0200) — per-hit inflicted credit was real 1995 behavior.
- **e82f54c (08-07):** finding-only + a console-flush watermark; two recorded wrong turns.
- **1324c81 (08-07):** inflicted credit lands on the OWNER's machine — Dispatch intercepts type 0 on a MASTER only; the type-0 arm of ScoreMessageHandler DELEGATES (wire deliveries go straight to the handler table, never the virtual Dispatch).
- **b2498ca (08-07):** the delegating type-0 arm must `return`, not `break` — the fall-through clobbered `scoreAward` to 0 and ran the base handler again (a duplicate-row generator, then harmless-by-luck).
- **a4bfb64 (08-07):** BOUND `scenarioRole` (was NULL forever — one commented-out lookup). This is what made deathPenalty=500 / killBonus=500 real; it also established that **-500 on an ordinary combat death is authentic** (gate = `advancedDamageOn` alone, @004c05c4 tail).
- **e0b91df (08-07):** correction — the death cost was never missing; it is invisible to the matchlog because of the direct base call. Added the ungated `[deathcost] ... -> APPLYING/SKIPPED` DEBUG_STREAM receipt (btplayer.cpp:716-724). Explicit lesson recorded: "a value that cannot appear in the log you are reading is not evidence of absence."
- **29b4d68 (08-07):** the +1000 MissionStarting seed grant. **5b7e481 (08-08):** mech+0x354 vestigial label, no behavior change.
## 3. The bench (scorepair.sh) — what it verified and what it could not see
`scratchpad/night14/scorepair.sh` (added by 46ff8dd): 2 nodes — B unarmed respawning target (player 3:1), A autofire missile killer that panic-ejects on a timer (player 2:1), relay via btconsole.py, 300 s. Its RESULT section is three checks:
1. `grep -ac "Mech::Reset" sc_b.log` — a count of B's resets (proxy for "kills A should have earned").
2. `grep -ah "SCORE\|KILL\|EJECT\|DEATH" matchlog_*.txt | head -25` — the score sequence.
3. `grep -a "scorepost" sc_a.log / sc_b.log` — **"scorepost" matches NOTHING in the codebase** (grep over game/ + engine/ returns zero hits); these two checks were dead on arrival and always print empty.
**What the captured receipts actually show:**
- `scratchpad/night14/sc.out` (02:56, pre-fix run) and `sc2.out` (10:28, the run cited in the commit): in BOTH, the `head -25` was exhausted by per-hit noise rows (type=0 award≈1.97 spam in sc.out; the victim node's `type=1 award=-0.00` spam in sc2.out) **before a single KILL / type=2 / DEATH row appeared**. The .out receipts therefore contain zero evidence about kills, deaths, or penalties. The commit's verified numbers ("kills 0->1->2, zero doubles, -900/-1050") match the raw matchlogs, so the verification was done by out-of-band manual matchlog reading, not by the bench's printed result.
- **PLAYER_DEAD is matched by none of the bench's grep patterns** — "DEATH" does not substring-match "PLAYER_DEAD". The death counter was never surfaced, let alone compared against real deaths.
- **`award=-500` can never appear in any matchlog** — the death cost is a direct `Player::ScoreMessageHandler` base call bypassing BTMatchLog (btplayer.cpp:712-715 says so explicitly; e0b91df is the commit that learned this). The only receipts are the `[deathcost]` DEBUG_STREAM lines in the node logs — which the bench never greps. (They DO exist in the post-fix run: `content/sc_a.log` has 4× `[deathcost] player 2:1 ... penalty=500 ... -> APPLYING`, `content/sc_b.log` has 2× for player 3:1 — so **at fix time the -500 was applying on both nodes**, provable only by artifacts the bench never printed.)
**The smoking gun in the pre-fix artifacts:** `scratchpad/night14/mlbak/matchlog_20260810_0250*.txt` (the run that reproduced #150) already contains the #162 death-side signature, in the same file as the double kill:
```
PLAYER_DEAD t=1827953 w=02:53:58.090 st=5 player=3:1 deaths=1 tally=1
PLAYER_DEAD t=1827953 w=02:53:58.091 st=5 player=3:1 deaths=2 tally=2
```
— two deathCount increments 1 ms apart for ONE death, immediately adjacent to the double kill rows (`type=2 award=501.96 kills=1` / `award=505.88 kills=2`, also 1 ms apart) that #150 was chasing. Post-fix (10:24 run, `content/matchlog_20260810_102334_1912.txt`) PLAYER_DEAD rows read singly (deaths=1 then deaths=2, minutes apart), so in THIS bench topology the fix incidentally quieted the double too — but nothing asserted it, and no one looked at the death side of either artifact.
## 4. The precise coverage hole
1. **The bench asserted only the kill side, and only manually.** Its scripted receipts were (a) a respawn count on the victim, (b) a `head -25` matchlog slice that noise-truncated before any kill/death row in both captured runs, and (c) two greps for a log tag (`scorepost`) that does not exist. Nothing scripted compared type-2 count vs death count, PLAYER_DEAD count vs actual deaths, or score totals vs expected arithmetic.
2. **PLAYER_DEAD was un-greppable by the pattern used** ("DEATH" ≠ "PLAYER_DEAD"), so death-count duplication — already present and visible in the pre-fix artifact — was structurally invisible to the bench.
3. **The -500 penalty is invisible to the matchlog by design** (direct base-handler call), and the bench never grepped the `[deathcost]` DEBUG_STREAM receipts or computed total-arithmetic deltas — the only two ways to see it. A regression that silenced the penalty would print an identical bench RESULT.
4. **The fix itself is asymmetric** and the bench could not detect the asymmetry: 46ff8dd's master-only gate + entry latch cover only `BTMechPostCombatReports` (mech.cpp:1270-1276); the death_tail's `BTMechPostVehicleDead` (mech.cpp:1335-1343) — the sole driver of `++deathCount`/`++deathTally`/PLAYER_DEAD and the death-cost block — kept the old `deathBlastArmed && IsMechDestroyed()` predicate, ungated by instance and un-latched. **[Inference]** That is the seam where #162's death-side breakage shipped: the kill side got both gates and a (manual) receipt; the death side got neither a gate nor a single line of bench assertion.

# TASK 1 — Binary truth: the report tail of `Mech::TakeDamageMessageHandler` @004a0230
Function: `FUN_004a0230` (`reference/decomp/all/part_012.c:14474-14837`, export tag `file=bt/mech.cpp`), bound as **Mech entity message id 0x12 TakeDamage** (`context/decomp-reference.md:265`). All claims below are [T1] read from this export unless flagged.
## 0. Entry protocol (context for the tail)
- **Replicant assert** — part_012.c:14613-14616: `(mech+0x28 & 0xc) == 4` → `Fail("Replicant Mech recieving takedamage", MECH.CPP, 0x3da)`. The handler body runs ONLY on the victim's master node.
- **Gyro bounce** — :14617-14624 (`mech+0x528` → `FUN_004b2980(gyro, msg+0x2c damageType, msg+0x30 amount)`); no messages.
- **THE LATCH** — :14625-14629: `local_14 = (FUN_0049fb54(mech) != 0)` = destroyed-at-ENTRY. `FUN_0049fb54` @0049fb54 (part_012.c:14174-14188) returns 1 iff `mech+0x40 (mode) == 2 || == 9`. **Note it does NOT count mode 10** (see §3 gate asymmetry).
- **lastInflictingID stamp** — :14631: `mech+0x43c ← msg+0x1c` (inflictor EntityID).
- **Party resolve** — :14630-14635: registry-find shooter entity by `msg+0x1c`; `local_1c = *(shooter+0x190)` = **SHOOTER's player**; `local_20 = *(mech+0x190)` = **VICTIM's own player**. Both resolved BEFORE the collision divert.
- **COLLISION DIVERT** — :14636-14639: `msg+0x2c (damageType) == 0` → `FUN_0049ffcc(mech, &msg+0x2c)` then **`goto LAB_004a07b5`** — jumps straight to the death tail (binary `jmp @0x4a0375 → 0x4a07b5`, `context/combat-damage.md:598-601`). Ram/wall damage therefore emits **NO id-0x16 report of any type** but STILL posts VehicleDead/blast if it killed. `FUN_0049ffcc` @0049ffcc (part_012.c:14374-14430) applies scaled internal-subsystem damage (gated `victimPlayer+0x268 != 0`, random subsystem via `FUN_004ac07c`) and **sends no messages**.
- **Damage loop** — :14655-14684: `local_28` (tally) += per-burst applied `msg+0x30` **plus** each critically-destroyed subsystem's value `*(subsys+0x108)` (:14669); `local_30` (vitalHit) = 1 when the struck zone's destroyed flag `zone[9]` goes 1 (:14674-14676); zone re-rolled per burst (:14680); loop breaks when bursts (`msg+0x58`) exhaust OR the mech becomes destroyed mid-volley (`FUN_0049fb54`, :14683). The do-while shape means **the first burst always applies, even on a corpse**, so tally can be nonzero when `local_14 != 0`.
All dispatches below are `(**(code**)(*player + 0xc))(…)` — vtbl slot 3 = `Entity::Dispatch`, which reroutes over the wire when the target player is a replicant on this node (engine/MUNGA/ENTITY.cpp:244-251 [T0], cited in `docs/KD_SCOREBOARD_PLAN.md:86`).
## 1. Wire layout of the id-0x16 report (ScoreMessage, sizeof 0x3C) [T1, static_assert-locked per decomp-reference.md:290-293]
`{+0x00 size 0x3C, +0x04 id 0x16, +0x08 =1, +0x0c destID null (DAT_00522524), +0x14 =0, +0x18 =0, +0x1c scoreAward, +0x20 type, +0x24 basis, +0x28 vitalHit, +0x2c zone, +0x30 inflictingSubsystemID (=msg+0x5c, engine T0 name), +0x34 senderMechID}`
## 2. The report block — three mutually structured id-0x16 dispatches
### local_14 == 0 (ALIVE at entry) — part_012.c:14685-14709
Re-tests `FUN_0049fb54` (:14686). If **destroyed NOW** (the alive→dead edge of THIS volley):
**Report A — type 2 KILL → SHOOTER's player** (:14688-14708; binary @0x4a04da, `combat-damage.md:605-608`; the KD plan calls this edge @0x4a052b-0x4a05ce, `KD_SCOREBOARD_PLAN.md:164`):
- `+0x1c scoreAward` = applied tally `local_28` (:14693,14700)
- `+0x20 type` = **2** (:14702)
- `+0x24 basis` = `*(*(victimPlayer+0x208) + 0x1c)` (:14691) = the **VICTIM role's killBonus** (role+0x1c; = 500 in shipped `Role::Default`) — this is the `@0x4a0506` killBonus read (`decomp-reference.md:477-478`)
- `+0x28 vitalHit` = `local_30`; `+0x2c zone` = `msg+0x24` (loop-ENTRY zone); `+0x30` = `msg+0x5c`; `+0x34 senderMechID` = **the VICTIM's own mech ID** (`mech+0x184`, :14692,14704)
- Dispatch :14708 → `local_1c` = shooter's player. On the victim's node that object is a **replicant**, so Dispatch reroutes it over the wire to the killer's master — where `BTPlayer` 0x16 `Score@0x4c02e4` case 2 runs CalcKillScore × (senderTonnage/ownTonnage), `killCount@0x27c++` (dual — the 1995 phantom partner increment), self-kill `fchs` negation (`decomp-reference.md:280-284`).
- Note: A and B are **exclusive** — a killing hit emits NO type-0.
If NOT destroyed now → `goto LAB_004a05d9` (falls into the same block the already-dead path uses):
**Report B — type 0 DamageInflicted → SHOOTER's player** (`LAB_004a05d9`, :14711-14734; @0x4a05d9):
- Gate: `local_28 != 0.0f` (the constant `_DAT_004a0c14` is a 0.0f literal parked after function end)
- `+0x1c scoreAward` = tally; `+0x20 type` = **0** (:14727); `+0x24 basis` = tally again (:14716,14728); `+0x28/2c/30` as above; `+0x34 senderMechID` = victim's mech ID (:14717,14729)
- Dispatch :14733 → shooter's player. Receiver side: `BTPlayer::Dispatch` override (`@004bffa0`, vtbl @00513300 slot 3) splits type 0 off to `@004c0200 ScoreInflictedMessageHandler` before base dispatch (`combat-damage.md:609-623`).
### local_14 != 0 (ALREADY DESTROYED at entry)
Enters directly at `LAB_004a05d9` → emits **Report B (type 0) if tally ≠ 0**. The believed "inflicted-only" is **half right**: the latch suppresses only the type-2 kill and the death tail — **Report C below still fires too**, because it sits OUTSIDE both branches.
### Report C — type 1 DamageReceived → VICTIM's OWN player (:14736-14759; @0x4a06c0) — **unconditional on the latch**
- Gate: `0.0f < local_28` only (:14736). Fires on non-lethal hits, on the killing volley, AND on corpse-hits whose first burst applied.
- `+0x1c scoreAward` = applied tally; `+0x20 type` = **1** (:14752); `+0x24 basis` = **INTENDED** damage = `msg+0x58 burstCount × msg+0x30 amount` (:14737,14753); `+0x28 vitalHit`; `+0x2c zone`; `+0x30 subsysID`; `+0x34 senderMechID` = **the SHOOTER's mech ID** (`msg+0x1c`, :14742,14754)
- Dispatch :14758 → `local_20` = victim's own player (master, local delivery). Receiver: `Score@0x4c02e4` case 1 = `(ownTonnage/senderTonnage) × role->CalcDamageReceivedScore(basis)` + the console VTVDamaged post (`decomp-reference.md:276-279`).
## 3. The death tail — `LAB_004a07b5` (:14760-14835; @0x4a07b5; also reached by the collision divert)
**Gate (:14761): `local_14 == 0 && (mech+0x40 == 9 || mech+0x40 == 10)`** — was-alive-at-entry AND now in death mode 9|10 (`combat-damage.md:691` calls +0x40 movementMode).
⚠ **Latch asymmetry [T1 fact, T4 as bug mechanism]:** the latch (`FUN_0049fb54`) counts modes **2|9** but the tail gate accepts **9|10**. If a mech can sit at mode 10 at the ENTRY of a subsequent TakeDamage (e.g. the 1ms-later duplicate hits of the killing volley), `local_14` stays 0 and the ENTIRE death tail — including VehicleDead — **re-fires**. Whether mode 10 persists across invocations in the binary is not established here; in the port it depends on when the reconstruction advances the mode. This is the one structural hole in the binary's own dedup and maps exactly onto the #162 deathCount multi-increment shape.
Dispatches inside the tail, in order:
**(1) VehicleDead — id 0x17, BT-extended sizeof 0x38 → the VICTIM's OWN player** (:14762-14775):
- `{+0x00 0x38, +0x04 0x17, +0x08 1, +0x0c destID null, +0x14 0, +0x18 0, +0x1c deathCount = -1 (0xffffffff, :14770), +0x20 dropZone EntityID = null, +0x28 = 0, +0x2c killed-by PLAYER EntityID = shooter-player's ID (local_1c+0x184 via `local_1c + 0x61` int* math, :14762,14773), +0x34 kill zone (msg+0x24, :14763,14774)}` — matches the locked layout at `decomp-reference.md:293-294`.
- Dispatch :14775 → `local_20` (victim's own player, master → local). Receiver: **BTPlayer 0x17 `VehicleDead@0x4c05c4`** — increments the DEATHS cell `+0x280` on BOTH victim and killer players (`inc [edi+0x280]/[ebx+0x280]` @0x4c0670-0x4c067a) and, in its tail `@004c07cd-0x4c0828`, gated on `advancedDamageOn` (player+0x264), **direct-calls the ENGINE base `Player::ScoreMessageHandler` @0042da20 with a type-1 ScoreMessage whose `scoreAward = −ScenarioRole::specialCaseDeathPenalty` (role+0x20, 500 in `Role::Default`)** — the −500 death cost (`decomp-reference.md:458-478`, `KD_SCOREBOARD_PLAN.md:88`).
- **This is the ONLY VehicleDead-class dispatch anywhere in FUN_004a0230**, and it is emitted at most once per handler invocation, solely under the was-alive latch + mode 9|10 gate. deathCount increment and −500 penalty share this single carrier: in the binary they cannot diverge (duplicate increments + missing penalty can only co-occur if the receiver path was split, which is a port-side property — inference, [T4] w.r.t. build 883).
**(2) Death explosion — engine message id 3, sizeof 0x5C — NOT dispatched, consumed locally** (:14776-14798):
- `{+0x04 id 3, +0x1c model/class 0x31, +0x28 = mech+0x4c0, +0x2c = 0x100, +0x30..0x48 = mech position/orientation (mech+0x100..0x118), +0x4c and +0x54 = victim mech EntityID}` (:14779-14797)
- Passed to `FUN_004302ec(&msg)` @004302ec (part_004.c:2362-2385): registry-finds the entity at msg+0x4c, `new`s a 0x1dc-byte object (ctor `FUN_00430180`, class data @DAT_004e6cc4) = the blast/Explosion entity, kept as `local_a0`. Nothing goes on the wire from here.
**(3) Delayed self-message — id 0x17 to the MECH, sizeof 0x1C — the respawn trigger, SCHEDULED not dispatched** (:14799-14811):
- `{0x1c, 0x17, 1, destID null, 0, 0}` (:14799-14804). Receiver id-space is the MECH's: mech-table **0x17 = SetBurningState@0049f674**, whose body actually randomizes position + graphicAlarm 2 + sim re-arm — the respawn (`decomp-reference.md:266`, label/body mismatch).
- Scheduled via `FUN_0041acbc(world+0x60, 3, mech, msg, when)` @0041acbc (part_002.c:4641-4658): allocates a scheduler node from pool 0x4e2fa4 (`FUN_0041a818(mech,msg,when)`) and inserts it in the world's delayed-delivery list. `when = *FUN_00414b60() (global clock, part_001.c:7125) + __ftol(mech+0x430)` — `FUN_004dcd94` is an ST0-arg `__ftol` the decompiler renders argless (`decomp-reference.md:278-279`); the float loaded is `mech+0x430` (:14805-14809), the respawn delay. **This is NOT a VehicleDead** despite sharing id 0x17 — per-receiver-class id spaces.
- (Do not confuse with mech id **0x16** = BalanceCoolant — the player/mech 0x16 ids are unrelated.)
**(4) Roster sweep** (:14812-14817): iterator over the `mech+0x418` list (`FUN_004a4eab`/`FUN_004a4ee9`), calls vtbl+0x48 per item — no messages.
**(5) Splash damage — the one tail helper that DOES send more messages** (:14818-14832):
- Gate: `victimPlayer+0x264 != 0 && victimPlayer+0x258 == 0` (:14819; +0x264 = advancedDamageOn per decomp-reference.md:460; the +0x258 slot is labeled suppressConsole in the VTVDamaged context — reuse here unverified [T4]).
- Builds damage spec `local_274 {type=2, amount=mech+0x520, victim position, __ftol(...)}` (:14820-14828) and calls `FUN_0042fad0(explosionEntity local_a0, victimMechID, &spec, radius = mech+0x524)` (:14831).
- `FUN_0042fad0` @0042fad0 (part_004.c:2059-2307) = the #89 SplashDamage: sweeps a ±radius box, and for each hit entity **dispatches a fresh id-0x12 TakeDamageMessage (size 100=0x64)** via `(**(code**)(*piVar3+0xc))(piVar3,&local_214)` (part_004.c:2276-2299), burst count = `max(1, __ftol(distance falloff))` (:2258-2261), inflictor ID stamped into the target's `+0x184`-relative slot from the passed mech ID (:2272-2275). Exclusions (:2203, :2226): the explosion entity itself, `*(explosion+0x1c8)` (its source — the dying mech, inferred from the ctor message carrying the mech ID [T4 on the identity]), and one under-recovered extra stack arg (`in_stack_00000024` — the decompiled 5-arg signature is short; [T4]). So the corpse does not re-splash itself, but every NEARBY mech's master re-enters this same handler with collateral damage during the killing volley.
**(6) ForceUpdate** (:14833): `FUN_004a4c54(mech, 1)` @004a4c54 (part_012.c:17180-17193): `mech+0x18 |= 1` (updateModel bit 0 = `Simulation::ForceUpdate`, corroborated `KD_SCOREBOARD_PLAN.md:131`); if destroyed, mask `& 0xfe03` still passes bit 0. Marks the dead mech for replication. No messages.
## 4. Emission matrix (per single handler invocation)
| Scenario at entry | type 0 → shooter | type 1 → victim | type 2 → shooter | VehicleDead 0x17 → victim's player | tail extras (blast/respawn-sched/splash) |
|---|---|---|---|---|---|
| alive, survives volley | ✔ (tally≠0) | ✔ (tally>0) | — | — | — |
| alive → DEAD this volley | — | ✔ | ✔ (basis=victim killBonus) | ✔ (exactly once) | ✔ |
| already destroyed (mode 2\|9) | ✔ (tally≠0) | ✔ (tally>0) | — | — | — |
| collision (type 0 dmg), killed | — | — | — | ✔ (killed-by = rammer's player) | ✔ |
| collision, survived | — | — | — | — | — |
Corrections to the task's priors: (a) the already-destroyed branch is **not** inflicted-only — the type-1 received report to the victim's own player also flows (Report C is outside both latch branches, gated only on tally>0); (b) the killing hit emits **no type-0** (A/B exclusive); (c) collision damage emits **no 0x16 at all** yet still runs the full death tail.
## 5. Relevance flags for #162 (inference, clearly marked [T4] against build 883)
- deathCount++ and the −500 penalty ride the SAME single VehicleDead message in the binary; 8 increments + 0 penalties means the port's VehicleDead emission or its receiver diverged from this map, not the binary's report logic.
- The only binary-native re-fire hole is the mode-10 latch gap (§3): destroyed-at-entry is tested as mode 2|9 while the tail fires on 9|10.
- "Duplicate pairs" of damage awards is consistent with B+C both existing per hit (one to each party) and/or corpse-hits still emitting B+C — and splash generates additional id-0x12 volleys during a kill.
==============================================================================
# FIELD RECEIPTS A/B — build 857 (night14) vs build 883 (night15), ticket #162
All paths below are absolute. Steam logs have no per-line timestamps (line numbers cited); matchlog receipts carry `t=` (ms tick) and `w=HH:MM:SS.mmm` wall clock. Receipt-format matchlogs were only collected from the ALIA machine on night15 (2 files) plus a dev-machine archive `scratchpad/night14/mlbak/` (builds 4.11.837–4.11.870, DESKTOP-AE1SU9U). The night14 field steam logs (build 857) contain NO receipt-format lines at all — no `SCORE t=`, no `PLAYER_DEAD` (0 matches in all four files); the 857 baseline evidence is the `[score]`/`[respawn]`/`[deathcost]` prose lines. [T2 throughout — all claims below are read directly from field logs]
## 1. BUILD-857 BASELINE (night14 steam logs)
**Multi-increment already existed in 857.** Clustering `[respawn] player X:1 death cycle START (death #N)` lines (same player, consecutive N, <200 lines apart) across the four logs:
| log | increments | real events | multiplicity |
|---|---|---|---|
| steam_20260808_a_dave_SCREECH.log | 9 | 6 | {1:4, 2:1, 3:1} |
| steam_20260808_b_santo_MSFIREFLY.log | 7 | 6 | {1:5, 2:1} |
| steam_20260808_c_michael_XIAOLONG.log | 11 | 9 | {1:7, 2:2} |
| steam_20260808_e_rajel_GAMERSLAB.log | 13 | 9 | {1:7, 3:2} |
| **TOTAL 857** | **40** | **30** | **{1:23, 2:4, 3:3}** |
**Every increment fired the full chain: KILL report + death cycle + deathcost.** KILL-report count == increment count in every log (9/9, 7/7, 11/11, 13/13) — this is the receipt-level shape of the 857 "kills doubled" bug that 46ff8dd later fixed.
**The penalty fired once per increment, gated on `advDmg`:** all 8 `-> APPLYING` lines have `advDmg=1`; all 32 `-> SKIPPED` have `advDmg=0`. Perfect 40/40 correlation. Verbatim triple-death, triple-penalty sample (dave log, C:/git/bt411/scratchpad/night14/steam_20260808_a_dave_SCREECH.log:59301-59317, one killing volley, scoreBefore stepping −500 each time — sequential application proof):
```
[score] *** KILL report *** -> shooterPlayer=0BE8BC20 tally=2.45198 bonus=500
[respawn] player 2:1 death cycle START (death #2) -- drop-zone hunt in 5s
[score] VehicleDead(-1): death #2, respawn hunt in 5s
[deathcost] player 2:1 advDmg=1 role=bound penalty=500 scoreBefore=4788.47 -> APPLYING
[death] VehicleDead(-1) dispatched to the owning player (killedBy=6:1 zone=21)
[score] *** KILL report *** -> shooterPlayer=0BE8BC20 tally=3.43099 bonus=500
[respawn] player 2:1 death cycle START (death #3) -- drop-zone hunt in 5s
[score] VehicleDead(-1): death #3, respawn hunt in 5s
[deathcost] player 2:1 advDmg=1 role=bound penalty=500 scoreBefore=4288.47 -> APPLYING
[death] VehicleDead(-1) dispatched to the owning player (killedBy=6:1 zone=21)
[score] *** KILL report *** -> shooterPlayer=0BE8BC20 tally=3.43232 bonus=500
[respawn] player 2:1 death cycle START (death #4) -- drop-zone hunt in 5s
[score] VehicleDead(-1): death #4, respawn hunt in 5s
[deathcost] player 2:1 advDmg=1 role=bound penalty=500 scoreBefore=3788.47 -> APPLYING
```
Other verbatim samples: single APPLYING (michael log :82303-82307, `advDmg=1 scoreBefore=1513.08 -> APPLYING`); triple SKIPPED (rajel log :57467-57481, player 6:1, 3× `advDmg=0 scoreBefore=6858.66 -> SKIPPED`, note scoreBefore does NOT move — skipped means no deduction); double SKIPPED (santo log :41879-41889, player 4:1, 2× `scoreBefore=1264.11 -> SKIPPED`).
**Are there award=-500.00 SCORE receipt lines?** No — in ANY build. In the entire mlbak receipt archive (builds 837–870) plus both 883 matchlogs, `award=` is never −500; the penalty is applied OUTSIDE the id-0x16 SCORE receipt and shows only as a silent −500 drop in the running `total=` between consecutive receipts. E.g. mlbak/matchlog_20260807_235237_15576.txt (4.11.837): total 0.00 → −500.00 between lines 32→40 with all awards −0.00; mlbak/matchlog_20260809_165517_13216.txt (4.11.865) line ~172: total 1000.00 → 501.97 (= −500 + a 1.97 award). The type= on the surrounding lines is type=1 (DamageReceived) with award=-0.00 — the −500 never rides a typed report.
**−499 eject evidence:** not present in the four night14 field steam logs (greps for `-499`/eject-score hit only coordinates and weapon-jam EJECT lines). The documented evidence is docs/OPEN_ISSUES_FOR_TESTERS.txt:87 — `#151 Panic eject costs -499: verified REAL 1995 scoring (your death scored as suicide + death penalty)` — i.e. −499 = suicide credit (+1) + death penalty (−500) [inference on the arithmetic; the −499 itself is a ledger claim, not in these logs].
## 2. BUILD-883 (night15)
**PLAYER_DEAD multiplicity — matchlog receipts (ALIA machine, both matches):**
- matchlog_20260810_213656_20476.txt (player 6:1 = Elengil): 8 PLAYER_DEAD, **5 real deaths**, multiplicity per event: **2, 1, 1, 3, 1** (events at w=21:39:49.419, 21:41:17.884, 21:43:13.203, 21:44:36.445, 21:46:29.337). Matches ticket #162's "5 real deaths → 8 increments" exactly.
- matchlog_20260810_223651_12120.txt (player 2:1, second match): 10 PLAYER_DEAD, **5 real deaths**, multiplicity: **1, 2, 2, 4, 1**.
- DEAD_NOTIFY count == PLAYER_DEAD count in both (8/8, 10/10); every PLAYER_DEAD is immediately preceded by its own `DEAD_NOTIFY ... link=<same ptr>`.
**All-machine distribution** (six steam logs, death-cycle-START clustering, all players' ledgers): a:{1:4,2:2}, b:{1:16,2:6}, c:{1:9,2:3,4:1}, d:{1:11,2:8,3:5}, e:{1:8,2:6,3:1,4:2}, f:{1:14,2:6,3:1,6:1} → **TOTAL {1:62, 2:31, 3:7, 4:3, 6:1}** — 163 increments over 104 events; ~40% of deaths multi-count, up to 6×.
**award=-500 count: 0** across both matchlogs (1,326 SCORE lines). No negative award of any magnitude exists (the only negative-looking value is the literal `award=-0.00` on every type=1 line — 745 of them, all exactly −0.00). Also **no silent −500 total-drops**: the only two total-vs-award mismatches (ml1 lines 305, 1117) are the type=2 kill receipts, which print `total=` BEFORE adding the award (next receipt shows total jumped +512.00: 1471.83 → 1992.58 = 1471.83+512+8.75). So in 883 the penalty is gone from the receipts entirely.
**Deathcost is still evaluated once per increment but always skips:** across all six steam logs 163 `[deathcost]` lines: **162× `advDmg=0 -> SKIPPED`, 1× `advDmg=1 -> APPLYING`** (steam_20260810_a_Dave_SCREECH-PC.log:5383 — player 2:1's FIRST death of the first round, `scoreBefore=1000 -> APPLYING`; the same player's later deathcost lines :19317, :26970 are `advDmg=0 -> SKIPPED`). Contrast 857 where 2:1's advDmg stayed 1 across deaths #1–#4 mid-round (scoreBefore 2907…4788). Receipt-level verdict: **the −500 path is intact but its `advDmg` gate reads 0 on (almost) every death in 883**, where it read 1 persistently for the same player in 857. Eleng's own machine evaluated deathcost for 6:1 exactly 8 times (once per increment) — all SKIPPED.
## 3. ELENGIL CORRELATION (6:1, matchlog_20260810_213656_20476.txt)
**death#1 @ w=21:39:49.419 — 2 increments.** DMG victim=6:19 within ±3s: from **7:19**: 12.000 (lvl .8806), 13.000 (lvl .6195) at .180/.181, and 8.750 burst=3 at .558 (post-death); from **5:19**: 1.964/3.432/4.913 (lvl .8488→.9130) then **type=4 amt=14.701 lvl=1.0000** → DEAD_NOTIFY → `PLAYER_DEAD deaths=1`, then **type=4 amt=15.701 lvl=1.0000** → DEAD_NOTIFY → `PLAYER_DEAD deaths=2`, then `DEATH ... killer=5:19 killdmg=15.701` 46ms later. **2 increments = 2 lethal (lvl=1.0000) damage rounds**, both from ONE shooter (5:19). Distinct shooters in window = 2; peers = 8.
**death#4 @ w=21:44:36.445 — 3 increments.** Window: **8:19** lands 9 rounds .596–.866 (4×3.446, 2×5.889, 13.000, 3.500 burst=9, 1.500 burst=2 — none lethal); **5:19** lands 7 rounds: 1.977×2, 3.444 (lvl .9236→.9653), then **4.903 lvl=1.0000** → PLAYER_DEAD deaths=5, **15.717 lvl=1.0000** → deaths=6, **15.717 lvl=1.0000** → deaths=7, all at t=613221000 same ms, DEATH latch 53ms later. **3 increments = 3 lethal rounds, all from ONE shooter.**
**Verdict: increment multiplicity == the number of KILLING-WINDOW DAMAGE ROUNDS** (damage applications with lvl=1.0000 that land between the killing blow and the DEATH-transition latch ~30–50ms later). It is NOT the number of distinct shooters (death#1: 2 shooters in window, 2 increments from one; death#4: 2 shooters, 3 increments from one; ml2's 4-increment event at 22:45:40.768 has all 4 lethal rounds from the single shooter 8:19 while earlier lvl=1.0000 rounds from 6:19 and 9:19 at .323/.628 produced NO increment). It is NOT the peer count (8 peers; multiplicity observed 1–6, mode 1–2). Each in-flight round of the killing volley that applies before the wreck latch re-fires DEAD_NOTIFY→PLAYER_DEAD.
## 4. THE "DUPLICATE SCORE PAIRS" IN 883 RECEIPTS
Same-key (t + player + type + award) SCORE multiplicity histograms: ml1 type=0 {1:98, **2:63**}, type=1 {1:46, 2:28, 3:10, 4:20, 5:3, 6:19}; ml2 type=0 {1:115, **2:120**}, type=1 up to ×6. The nonzero-award duplicated groups are **all type=0 (DamageInflicted)**; pair members carry **IDENTICAL award and DIFFERENT, sequentially-advancing totals** — e.g. ml1 lines 45-48:
```
SCORE t=612804640 w=21:37:40.090 st=5 player=6:1 type=0 award=1.97 total=1001.97 kills=0
SCORE t=612804640 w=21:37:40.090 st=5 player=6:1 type=0 award=1.97 total=1003.94 kills=0
SCORE t=612804640 w=21:37:40.090 st=5 player=6:1 type=0 award=3.44 total=1007.38 kills=0
SCORE t=612804640 w=21:37:40.090 st=5 player=6:1 type=0 award=3.44 total=1010.82 kills=0
```
**BUT these type=0 pairs are not duplicates.** Each pair member maps 1:1 to a distinct weapon event: the volley above is FIRE wpn=25 amt=3.439 / wpn=26 amt=3.439 / wpn=27 amt=1.971 / wpn=28 amt=1.971 (twin-mounted lasers, ml1 lines 41-44), and the following `award=13.00` pair maps to PROJ wpn=22 + wpn=24 both amt=13.000 (lines 49-52). Aggregate: SCORE type=0 count ≤ hit-event count in both matchlogs (224 vs 242; 355 vs 408 — the excess hits are missile rounds paid as lump awards like 35.00=4×8.75). A build-865 control (mlbak/matchlog_20260809_165517_3316.txt lines 16-19: 2 FIRE → 2 identical 1.97 awards; 105 type=0 vs 108 hits) shows the identical pattern pre-883. **Verdict: the type=0 "duplicate pairs" are twin-weapon awards, present in old builds, correctly paid once per hit — not part of bug #162.** What IS genuinely duplicated per killing volley: the DMG/type=1 receipt (one per damage round, always award=-0.00, ×2–×6 same-ms) and DEAD_NOTIFY/PLAYER_DEAD (the real bug). Kill credit is exact in 883: `SCORE type=2 award=512.00` / `award=500.98` once per kill, SBMIRROR +1 steps (ml1 lines 305, 1117).
==============================================================================
# TASK 2 — Binary truth: 1995 player-side score/K-D handlers + replication
All addresses verified against the 2026-08-06 re-export (`reference/decomp/all/part_013.c`, `part_012.c`, `part_004.c`) and, where load-bearing, re-verified with raw capstone disasm of `content/BTL4OPT.EXE` (`tools/disas2.py`). Tier tags inline.
## 0. The handler table (who consumes what) [T1, byte-scanned table + export]
BTPlayer message table (20-byte rows, 6 entries — matches the T0 `PLAYER.h:235-240` enum `DropZoneReply=Entity::NextMessageID(0x15), Score(0x16), VehicleDead(0x17), MissionStarting(0x18), MissionEnding(0x19), NextMessageID(0x1a)`):
- **0x15 DropZoneReply → `FUN_004bffd0`** (part_013.c:18814)
- **0x16 Score → `FUN_004c02e4`** (part_013.c:18941) — the type-0/1/2 switch
- **0x17 VehicleDead → `FUN_004c05c4`** (part_013.c:19066; formerly an export gap, now exported AND raw-disasm-confirmed this pass)
- **0x1a ScoreUpdate → `FUN_004c02a8`** (part_013.c:18926)
- `FUN_004c0200` "ScoreInflicted" (part_013.c:18896) is bound in NO table entry — **dead code in 1995** (confirms `context/decomp-reference.md:273-275`).
## 1. The id-0x16 Score handler `@0x4c02e4` — all three arms [T1]
Entry: replicant Verify (`(this+0x28 & 0xc)==4` → Verify print, btplayer.cpp line 0x1e9), then **MissionEnding gate `this+0x40 != 4`** (whole body skipped during mission end). `iVar3 = GetEntityPointer(msg->senderMechID @+0x34)`; `local_c = playerVehicle(+0x1fc)`.
**type 0 (DamageInflicted)** — part_013.c:18970-18973: nothing but `Verify` (line 0x296). `local_10` (the award local) is **never written**, and the shared tail (part_013.c:19015-19016) still runs: `msg->scoreAward(+0x1c) = local_10 /*UNINITIALIZED*/; FUN_0042da20(this,msg)` → **folds stack garbage into engine currentScore(+0x1c8)** — the shipped 1995 bug the KB documents (`decomp-reference.md:275-276`). No counter increments.
**type 1 (DamageReceived)** — part_013.c:18974-18991: only if `senderMech != own vehicle`: `award = (ownTonnage(+0x4bc)/senderTonnage) × CalcDamageReceivedScore(basis@msg+0x24)` where **`FUN_00429b94` (part_003.c:10156-10160) = `−(basis × role->damageReceivedModifier(+0x10))`** — a NEGATIVE (penalty). Then the console VTVDamaged post (code 5; gated ConsoleHost && `!suppressConsole(+0x258)`). **If senderMech == own vehicle (self-inflicted), `local_10` stays uninitialized and the tail still folds it** — same uninit-fold class as type 0 (NEW this pass). No counter increments. dfltrole `dmgRcv=0` ⇒ award 0 in shipped content.
**type 2 (Kill)** — part_013.c:18992-19013:
- `award = CalcKillScore(this, &basis@+0x24, victimMech, tally@+0x1c) × (victimTonnage/ownTonnage)`.
- **`CalcKillScore @0x4c052c`** (part_013.c:19027-19060): team game (`freeForAll(+0x250)==0`) + same `teamName(+0x20c)` → `local_8 = −friendlyFirePenalty(role+0x14)`; else `local_8 = victimMech->avgZoneDamage(+0x354) × damageBias(role+0x18) + 1.0 (@0x4c05c0)`; returns `(basis + tally) × damageInflictedModifier(role+0xC) × local_8`.
- **Suicide (`victimMech == own vehicle`): `local_10 = -local_10` (the `fchs`) and NO killCount increment.**
- Else — **the dual killCount++, exact context** (part_013.c:18998-19001; `inc [+0x27c]` @0x4c0397/@0x4c03a3):
```c
else {
*(int *)(param_1 + 0x27c) = *(int *)(param_1 + 0x27c) + 1; // shooter (this) killCount++
piVar1 = (int *)(*(int *)(iVar3 + 400) + 0x27c); // victimMech+0x190 -> victim's player
*piVar1 = *piVar1 + 1; // PHANTOM: victim's player killCount++ (wrong column)
}
```
On the shooter's node the second object is the **victim's replicant player copy** — never corrected in 1995 (no replication, §4).
- StatusMessage `{type 0 "Destroyed", victim player, 6.0s}` (pool @0x512f6c, vtable @0x513344) added to this player; if `victimMech == objectiveMech(+0x284)` → clear-target `FUN_004b04d8` via own vehicle's roster head (+0x128).
- Tail (all types): `msg->scoreAward = award; FUN_0042da20(this,msg)` → `currentScore(+0x1c8) += award; playerVehicle->RespondToScoreMessage(msg)` (part_004.c:449-450 ≡ T0 `engine/MUNGA/PLAYER.cpp:143,150`).
**killCount(+0x27c) is written NOWHERE else in the image** — only the type-2 arm.
## 2. WHERE deathCount++ lives and WHERE the deathPenalty is subtracted [T1, raw disasm this pass]
Both live in **`BTPlayer::VehicleDeadMessageHandler @0x4c05c4`**, in the **`msg->deathCount(+0x1c) == -1` arm** — one straight-line block, no exit between them:
- Entry gates: `this+0x40 != 4` (MissionEnding); `msg+0x1c == -1` else → engine base `FUN_0042db80` (drop-zone hunt); **`deathPending(+0x290) == 0`** guard @0x4c05f7.
- `edi = GetEntityPointer(msg+0x2c)` = the **killer's PLAYER** (the BT 0x38-byte extension field).
- StatusMessage `{type 1 "KILLED BY", killer player, 6.0s}` @0x4c062d-0x4c0668.
- **The deaths increment @0x4c0670-0x4c067f:**
```
0x4c0670: cmp ebx, edi ; victim(this) vs killer player
0x4c0672: je 0x4c067a ; self-kill: skip the partner bump
0x4c0674: inc dword ptr [edi + 0x280] ; killer's player deaths++ (wrong-column slip; on the victim's node this is the killer's REPLICANT copy)
0x4c067a: inc dword ptr [ebx + 0x280] ; victim's deaths++ (the real DEATHS cell) — UNCONDITIONAL
```
- Console death notice (code 5, `FUN_004c18cc`) if `!suppressConsole(+0x258)` && console present.
- Revenge lock `objectiveMech(+0x284) = killerPlayer->playerVehicle(+0x1fc)` @0x4c06dd.
- Death sweep `FUN_0049fe0c(playerVehicle, 0)` @0x4c06e9 (DeathShutdown arg 0).
- Lives branch on `role(+0x208)->returnFromDeath(+0x28)`:
- `> 0`: re-post the SAME VehicleDead to **SELF** at Now + **5.0 s** (@0x4c0830) with `msg->deathCount ← this->deathCount(+0x200)` (raw disasm recovered `mov esi,ebx` @0x4c0731 — the Post target is the player, matching the export).
- `< 1` (out of lives): post `{size 0x1c, id 0x18}` to the **VEHICLE** at Now + **10.0 s** (@0x4c0838) — in the Mech id space 0x18 = ClearBurningState; no respawn.
- **THE DEATH PENALTY @0x4c07cd-0x4c0825** — BOTH branches converge here (`jmp 0x4c07cd` @0x4c0754):
```
0x4c07cd: mov ecx, [ebx + 0x264] ; advancedDamageOn — THE ONLY GATE
0x4c07d5: je 0x4c0828 ; off -> no penalty
0x4c07d7: mov eax, [ebx + 0x208] ; scenarioRole
0x4c07dd: fld dword ptr [eax + 0x20] ; specialCaseDeathPenalty (dfltrole = 500)
0x4c07e0: fchs ; negate
... build a BARE 0x20-byte engine ScoreMessage {id 0x16, scoreAward@+0x1c = -penalty} (NO type field — the msg ends at 0x20)
0x4c0820: call 0x42da20 ; DIRECT call to ENGINE Player::ScoreMessageHandler
```
So the −500: **victim's master node, inside the id-0x17 VehicleDead(-1) arm, gated ONLY on `advancedDamageOn(+0x264)`, amount = `role+0x20` read live, applied by a DIRECT call** (no Dispatch → no reroute, no BT type switch, no Verify) into `currentScore(+0x1c8)` + `playerVehicle->RespondToScoreMessage`. Confirms `decomp-reference.md:458-478` (#118) and adds: **the penalty also applies on the out-of-lives path.**
**The engine respawn counter is a DIFFERENT field:** `Player::deathCount(+0x200)` (ctor seed −2, `PLAYER.cpp:777`; zeroed at first spawn, part_013.c:18834) increments ONLY in **`FUN_004c012c`** (part_013.c:18872, the DropZoneReply respawn helper) — once per completed respawn cycle, alongside `msg->deathCount` restamp, `role->returnFromDeath(+0x28)--`, **`ForceUpdate` (`or word [ebx+0x18],1`)**, sim-state SetLevel(1)=DropZoneAcquired, respawn-location choose (advancedDamageOn → the ORIGINAL drop @DAT_00524b38, else the assigned zone), a delayed self re-post (the 2-pass latch), and **clearing `+0x290` and `suppressConsole(+0x258)`** (part_013.c:18887-18888).
### NEW [T1, whole-image byte scan]: the `deathPending(+0x290)` guard is NEVER SET in 1995
Every code-section instruction touching disp32 0x290: `push 0x290` @0x429294 (an immediate, not a member); zero-writes @0x4b77fd (different object), **@0x4c01e5 (`FUN_004c012c`: = 0)**, **@0x4c0c07 (BTPlayer ctor: = 0)**; the lone READ @0x4c05f9 (the handler guard). **No instruction ever writes it non-zero.** The 1995 receiver has NO dedup — single increment/single penalty is guaranteed solely by the SENDER emitting exactly one VehicleDead per death (§3). Implication for #162: in the binary, deaths++ (@0x4c067a) and the penalty (@0x4c07cd) are one straight-line block — "deaths multi-increments while the penalty never applies" is impossible in a faithful transcription; it requires (i) `advancedDamageOn==0`, (ii) an unbound/zero role (+0x20==0 — the pre-2026-08-07 port state), or (iii) a port-side early exit between the two.
## 3. The sender: `Mech::TakeDamageMessageHandler @0x4a0230` report tail [T1] (part_012.c:14474-14837)
Runs ONLY on the **victim mech's MASTER node** (replicant Verify at entry, line 0x3da; field: 0/18818 DMG rows inst=R). Per killing/damaging hit:
1. **Destroyed-at-entry latch: `local_14 = FUN_0049fb54(this)` (IsDisabled) at ENTRY** — a hit landing on an already-dead mech can never re-send kill/VehicleDead.
2. `lastInflictingID(+0x43c) ← msg->inflictingEntityID(+0x1c)` — every hit, last-writer-wins.
3. **`damageType(msg+0x2c) == 0` (Collision) → `FUN_0049ffcc` and `goto` the death tail — SKIPS ALL THREE id-0x16 reports.** 1995 ram kills award NO kill score and NO killCount; they still produce VehicleDead → deaths + penalty (state-9 timing inside FUN_0049ffcc not read this pass, [T3]).
4. Burst loop applies damage; `local_28` accumulates applied damage + crit contributions; the loop breaks when the mech goes disabled mid-burst.
5. Reports, all ScoreMessage id 0x16 size 0x3C `{+0x1c tally, +0x20 type, +0x24 basis, +0x28 vitalHit, +0x2c zone, +0x30 subsysID, +0x34 senderMechID}`:
- **KILL EDGE** (alive at entry && disabled after) part_012.c:14685-14708: **type 2 → Dispatch to the SHOOTER's owning player** (`*(shooterMech+0x190)`; a replicant locally → `Entity::Dispatch` reroutes to the shooter's master). `tally = local_28` (applied damage of the volley), **`basis = the VICTIM's own `role->killBonus(+0x1c)`** (the @0x4a0506 read; dfltrole 500), `senderMechID = the victim mech's own ID(+0x184)`.
- **Else** (still alive, or wreck-shooting), if `local_28 != 0` (part_012.c:14710-14734): **type 0 → the SHOOTER's player** (tally = basis = local_28) — lands in the 1995 dead/uninit arm (§1).
- If `local_28 > 0` (part_012.c:14736-14758, independent — ALSO fires on the kill edge): **type 1 → the VICTIM's OWN player** (local master → synchronous). `tally = local_28`, `basis = burstCount(+0x58) × damageAmount(+0x30)` (nominal volley), `senderMechID = the inflicting entity (msg+0x1c)`.
6. **DEATH TAIL** (part_012.c:14760-14835): gate `local_14 == 0 && (this+0x40 == 9 || == 10)` (10 = eject) — the one-shot alive→dead edge. Builds **BT VehicleDeadMessage `{size 0x38, id 0x17, deathCount(+0x1c) = -1, dropZoneID = Null, +0x28 = 0, +0x2c = the killer's PLAYER EntityID (`shooterPlayer+0x184`), +0x34 = kill zone}`** → **Dispatch to the VICTIM's OWN player** (synchronous, master). Then: death-effect broadcast (id 3, 0x5c), a delayed SetBurningState (id 0x17, 0x1c) to the mech itself (delay = `mech+0x430`), watcher sweep, console damage-effect notify (advancedDamageOn && !suppressConsole), `FUN_004a4c54(this,1)`. **Exactly one VehicleDead per death, sender-side guaranteed.**
## 4. Replication: what rides the Player update record [T0 + T1]
- `Player::WriteUpdateRecord` (`PLAYER.cpp:645-661` ≡ binary `FUN_0042e2e4`, part_004.c:859-867): `Entity::WriteUpdateRecord`, `recordLength = 0x3c`, **`record+0x2c = currentScore(+0x1c8)`, `record+0x30 = dropZoneLocation(+0x1d0)`** — nothing else. `ReadUpdateRecord` (`PLAYER.cpp:631-641` ≡ `FUN_0042e2ac`) applies the same two.
- **BTPlayer does NOT override** — vtable @0x513300 slots 6/7 = 0x42e2ac/0x42e2e4, the engine's (KD plan §1 [T1]).
- Therefore in 1995: **`currentScore(+0x1c8)` is the ONLY replicated scoring field.** `killCount(+0x27c)`, `deaths(+0x280)`, respawn `deathCount(+0x200)`, and the bank `+0x278` NEVER cross the wire; each is authoritative (and only meaningful) on the single node where its increment ran. Bystanders show 0/0 K/D for everyone all mission; the two wrong-column partner increments (on replicant copies) are locally visible and never corrected.
- `Player::CalcRanking` (`PLAYER.cpp:542-626` ≡ `FUN_0042e1ac`): per-node sort of the local "Players" group **by `currentScore`** → `playerRanking(+0x1cc)`/`playerHighlighted(+0x1c4)`. Runs in Player/CameraShip simulation each frame.
- **The scoreboard PilotList `@0x4cabd0`** (part_014.c:7656-7657) draws per row exactly `(float)[player+0x27c]` (KILLS) and `(float)[player+0x280]` (DEATHS) — no score cell in this widget.
- **`+0x278` is a pending-score BANK, not the score** (NEW precision): sole writer = the dead `@0x4c0200` (`+0x278 += tonnageRatio × CalcKillScore(...)`, self-negated); the flusher `FUN_004c083c` (part_013.c:19164-19192, called from the BTPlayer master performance `FUN_004c0904`) every **10.0 s** (@0x4c08fc) self-Dispatches a `{0x20, id 0x1a, award = +0x278}` ScoreUpdate then zeroes the bank; handler `@0x4c02a8` = Verify-master + engine fold. Design = replicant-side observed-score banking with reroute-to-owner; dead in 1995 because the only writer is unbound. The periodic console score post (every 15.0 s @0x4c0bc0) reads **+0x1c8** (`param_1[0x72]`, part_013.c:19274).
## 5. THE 1995 FLOW — one death event (shooter S kills victim V, weapon damage, advanced damage ON)
On **V's node** (V master), synchronously inside the killing `TakeDamageMessage` (id 0x12) processing:
1. `V.mech.lastInflictingID ← S.mech` ; damage applied; tally accumulated.
2. **[out] ScoreMessage 0x16 type 2** → dispatched at S.player-replicant → rerouted to S's node (`ENTITY.cpp:244-251`).
3. **[sync] ScoreMessage 0x16 type 1** → V.player (master): `V.currentScore(+0x1c8) += (Vt/St) × −(basis × rcvMod)` (0 with dfltrole); console VTVDamaged.
4. **[sync] VehicleDead 0x17 (deathCount=−1, killer=S.player, zone)** → V.player (master):
a. "KILLED BY" ticker; b. `S.player-replicant.deaths(+0x280)++` (wrong column, local-only); c. **`V.deaths(+0x280)++`** ← THE death count; d. console death notice (unless suppressConsole — eject sets it); e. `V.objectiveMech = S.vehicle`; f. DeathShutdown(0) sweep; g. lives>0 → repost VehicleDead(deathCount=+0x200) to self @ +5 s; h. **`V.currentScore(+0x1c8) −= role.specialCaseDeathPenalty(500)`** — direct engine call, advancedDamageOn-gated. No ForceUpdate anywhere in this block.
On **S's node**, when the rerouted type-2 executes on S.player (master):
5. `award = (killBonus + tally) × dmgInfMod × (V.avgZoneDmg × bias + 1) × (Vt/St)` [or `−ffPenalty` same-team; negated + no counters on suicide]; **`S.killCount(+0x27c)++`**; **`V.player-replicant.killCount(+0x27c)++`** (phantom, local-only); "DESTROYED" ticker; revenge clear-target; `S.currentScore(+0x1c8) += award`.
Respawn (V's node): +5 s repost → engine `FUN_0042db80` (gate `msg->deathCount == +0x200 && simState != DropZoneAcquired`): closest non-"win" DropZone, `AssignDropZone{reply 0x15, deathCount}` → DropZone dispatches **DropZoneReply 0x15** → `FUN_004bffd0`: stale gate (`msg+0x38 == +0x200`), MissionEnding gate; pass 1 (state≠1) → **`FUN_004c012c`: `deathCount(+0x200)++`, `returnFromDeath--`, ForceUpdate, state←1, location choose, clear +0x290/+0x258, delayed self-repost**; pass 2 (state==1) → state←2, **`Mech::Reset(vehicle, loc, 1)` (`FUN_0049fb74`)**.
Convergence: peers learn ONLY `currentScore` (and position) from the Player update record; K/D never converge in 1995.

# TASK 3 — The as-built scoring/death chain at HEAD (build 883, post-46ff8dd)
## 1. Producer: `Mech::TakeDamageMessageHandler` (game/reconstructed/mech.cpp:1031-1344)
Handler anatomy, in execution order:
| Step | Site | Notes |
|---|---|---|
| `destroyedAtEntry = IsMechDestroyed()` | mech.cpp:1039 | #150 entry latch (added in 46ff8dd), sampled at handler ENTRY; `IsMechDestroyed()` = `graphicAlarm >= 9` (mech.hpp:1145, impl mech4.cpp:2215) |
| gyro bounce, lastInflictingID/Damage, HUD threat | mech.cpp:1063-1087 | no score effect |
| `deathBlastArmed = !(MovementMode()==9 \|\| MovementMode()==10)` | mech.cpp:1119-1120 | the OTHER once-latch, movementMode-based — arms the death tail |
| COLLISION DIVERT (`damageType==0`) | mech.cpp:1142-1146 | `DistributeCollisionDamage` then `goto death_tail` — **bypasses the report tail entirely** (a collision death posts VehicleDead but NO 0x16 reports; credits no one — documented authentic, mech.cpp:1130-1140) |
| zone/burst application loop | mech.cpp:1193-1241 | accumulates `damageTally` (applied damage + crit bonuses, :1216/:1227), `zoneDestroyed` (:1229) |
| **REPORT TAIL master-gate** | mech.cpp:1270 | `if (GetInstance() != ReplicantInstance)` → `BTMechPostCombatReports(this, msg, damageTally, zoneDestroyed, reportZone, !destroyedAtEntry && IsMechDestroyed())` (:1272-1275). The kill flag = the 0→1 edge of `IsMechDestroyed()` across THIS call |
| matchlog `DMG` receipt | mech.cpp:1283-1304 | prints `inst=M/R` (:1294) — runs on BOTH instances, ungated |
| **DEATH TAIL** | mech.cpp:1335-1343 | `if (deathBlastArmed && IsMechDestroyed())` → `BTMechPostVehicleDead(...)` (:1339) + `BTApplyDeathSplash(this)` (:1342) |
**The critical asymmetry (46ff8dd scope):** the commit gated ONLY the 0x16 report tail (mech.cpp:1270) and only the report tail got the `destroyedAtEntry` edge-latch. The DEATH TAIL is (a) **not instance-gated** — it runs on replicant victim copies too — and (b) latched on `deathBlastArmed` (movementMode), **not** on `destroyedAtEntry`. On a replicant, movementMode cannot flip to 9/10 until the owner's death update record round-trips (replicants reach mode 9 only via replicated simulationState — mech4.cpp:2721-2725), while `graphicAlarm` IS raised to 9 locally by the damage application itself (mechdmg.cpp:495, :497, :548, :710, :798 — leg-gone/vital-zone/vital-subsystem/mech-kill writers that run wherever damage is applied). So inside the round-trip window **every additional salvo of the killing volley re-enters the death tail on each peer's replicant copy**: `deathBlastArmed`=1 (mode still 1) && `IsMechDestroyed()`=1 → another VehicleDead + another death splash, per salvo, per peer. This is byte-for-byte the same mechanism 46ff8dd proved for the duplicated kill reports ("two type-2 arms 1ms apart, victim inst=R" — commit message) — the fix covered the reports and left the tail.
## 2. `BTMechPostCombatReports` (game/reconstructed/btplayer.cpp:2574-2691) — every dispatch
Resolution: `shooter` from registry by `msg->inflictingEntity` (:2595), `shooter_player = shooter mech playerLink` (:2598), `victim_player = victim playerLink` (:2600).
| Block | Guard | Message | Destination | kill-flag use |
|---|---|---|---|---|
| **A** kill (:2602-2644) | `if (newly_destroyed)` && `shooter_player != 0` | ScoreMessage id 0x16 **type 2**, scoreAward=damageTally, damageAmount=victim role killBonus (:2612-2626) | `shooter_player->Dispatch(&kill)` (:2627) — replicant on the victim's node → Entity::Dispatch reroutes to killer's host (ENTITY.cpp:244-251) | **consumed** — sole gate. killer==victim IS dispatched (eject/suicide; handler negates) :2608-2610. Else-arm: matchlog `NOCREDIT` (:2633-2644) |
| **B** inflicted (:2646-2667) | `else if (damage_tally != 0 && shooter_player != 0)` | id 0x16 **type 0**, award & basis = tally (:2658-2665) | `shooter_player->Dispatch(&inflicted)` (:2666) | **consumed via the else** — the killing hit posts NO inflicted report (kill replaces it) |
| **C** received (:2669-2690) | `if (damage_tally > 0 && victim_player != 0)` — NOT an else | id 0x16 **type 1**, award=tally, damageAmount=INTENDED (burstCount×amount) (:2678-2688), senderMechID=INFLICTOR | `victim_player->Dispatch(&received)` (:2689) — master on the victim's own node → local | **ignored** — runs after A too, kills included (binary behavior, :2672-2674) |
All three sit INSIDE the mech.cpp:1270 master-gate. Per-TakeDamage cadence: B+C once per non-lethal hit, A+C once on the killing hit, B+C again on every post-mortem salvo that still tallies damage on the wreck (destroyedAtEntry=1 → newly=0 → the "inflicted-only path", mech.cpp:1038).
## 3. `BTMechPostVehicleDead` (btplayer.cpp:2702-2758)
Builds `BTPlayer::VehicleDeadMessage` id 0x17, 0x38 bytes, killed_by = shooter PLAYER EntityID, killZone (:2748-2752); engine-base `deathCount` ctor-defaults to **-1** (engine/MUNGA/PLAYER.h:111,120; btplayer.hpp:183) → every dispatch takes the consumer's "-1 immediate death notification" arm. Owner resolved via playerLink with the #55 mission-player fallback (:2711-2723); `DEAD_NOTIFY` matchlog (:2724). `owner->Dispatch(&vehicle_dead)` (:2753) — on a peer node `owner` is a replicant player → reroute to the owning host (ENTITY.cpp:244-251). **No instance gate, no once-per-death latch of its own** — it fires as often as the death tail fires (see §1 asymmetry).
`BTApplyDeathSplash` (mech4.cpp:1382-1428): gates = victim player's `advancedDamageOn` && !`suppressConsole` (:1399; punch-outs never blast), radius/damage authored per chassis; dispatches a type-2 TakeDamage (inflictor = the DYING mech, :1337 via BTSplashCore :1426) to every live mech in radius via `e->Dispatch(&td)` (mech4.cpp:1335-1338). Because the death tail runs on every node's copy, a bystander's master can receive the SAME death blast once locally (its own node's replicant-victim tail) and once over the wire (the victim-master's tail, rerouted) — **each application then posts its own Block-C received award: a structural producer of "damage awards in duplicate pairs"** [T3 inference from as-built structure; not yet log-confirmed].
## 4. Consumers (btplayer.cpp) — everything that mutates score/killCount/deathCount
Handler table: btplayer.cpp:346-356 (DropZoneReply, VehicleDead, Score, ScoreInflicted, ScoreUpdate, MissionStarting, MissionEnding).
### 4a. `BTPlayer::Dispatch` type-0 interceptor (:891-917)
Local id-0x16 type-0 dispatches, `GetInstance()==MasterInstance` only (:911) → `ScoreInflictedMessageHandler`; otherwise falls to `Player::Dispatch` (replicant → wire reroute). Wire deliveries NEVER pass through this vtable — they land in the handler table via Receive (:1092-1105).
### 4b. `ScoreInflictedMessageHandler` (:963-1022) — type 0
Verify-asserts type==0 (:971-980); drops if `our_mech==0` (:994); `currentScore += (tonnage ratio) * award`, negated if target==self (:1001-1012); `ForceUpdate()` (:1013); **matchlog receipt `SCORE ... type=0`** (:1018-1021). No instance guard at all.
### 4c. `ScoreUpdateMessageHandler` (:1032-1046)
Replicant check is `Verify(False, ...)` (:1036) then falls through to the base handler (:1045).
### 4d. `ScoreMessageHandler` (:1057-1279) — the 0x16 type-1/2 consumer
- **Replicant guard is a no-op at runtime**: `Verify(False, ...)` (:1061-1067) — and `Verify` compiles to NOTHING: no `DEBUG_LEVEL` is defined anywhere in the build (grep of CMakeLists), so engine/MUNGA/STYLE.H:10-14 defaults DEBUG_LEVEL=0 → DEBUGOFF.h:42 `#define Verify(c)` (empty). Same for :973 and :1036. **If a 0x16 ever reaches a replicant player copy, the handler executes fully on it.** Delivery-side, `EntityManager::ReceiveNetworkPacket` (engine/MUNGA/NTTMGR.cpp:107-149) posts an inbound wire message to whatever LOCAL copy matches the entityID — **no instance check** — so nothing structural prevents that.
- MissionEndingState drop (:1073-1076).
- **type 0** (:1086-1115): delegates to ScoreInflictedMessageHandler and RETURNS (wire-rerouted inflicted reports land here; :1114-1115).
- **type 1** DamageReceived (:1117-1169): award = tonnage-ratio × `scenarioRole->CalcDamageReceivedScore(msg->damageAmount)` — guards sender/our mech non-null, sender≠self, role bound (:1125-1131); self-hit → award stays 0 (deliberate deviation, :1132-1136); console VTVDamaged side-message (:1149-1167).
- **type 2** Kill (:1171-1241): award = tonnage-ratio × `CalcInflictedScore(msg->damageAmount, sender_mech, msg->scoreAward)` (:1188-1190); `sender==our_mech → award = -award` (suicide/eject, :1192-1195 — the previous build's measured **-499**); else `++killCount` (:1204) **and `++sender_owner->killCount`** — the binary's wrong-column slip reproduced on the VICTIM's (replicant) player copy (:1206, banner :2376-2389); status ticker (:1219-1228); objective notify (:1234-1240).
- Common tail: `message->scoreAward = award` (:1252); **matchlog `SCORE ... type=<1|2>`** (:1257-1262); `currentScore += award` — via direct add if vehicleless (:1264-1268) else `Player::ScoreMessageHandler` (:1270); `ForceUpdate()` (:1278).
### 4e. `VehicleDeadMessageHandler` (:418-771) — the deathCount writer
- MissionEndingState swallow (:426-439).
- `deathCount != -1` branch (:441-539): the +5s re-post / -2 probe → drop-zone hunt via engine base (:537). Moot if mech alive again (:452-462).
- **`deathCount == -1` arm** (:541-771), the death notification. Dedup gate `if (deathPending != 0) return` (:546-558) — **but `deathPending` is SET at :559 and CLEARED at :768 inside the SAME synchronous invocation** (the #81 fix moved the clear here, banner :739-767). A queued/wire duplicate arriving even 1ms later sails through. Per accepted -1 message: `++deathCount` (:582), `message->deathCount = deathCount` (:583), `++deathTally` (:592), **matchlog `PLAYER_DEAD`** (:601-602), life debit (:606-610), ForceUpdate (:634), `killerName` (:673), +5s respawn re-post (:690-695), **THE DEATH COST** (below), latch clear (:768), `suppressConsole=0` (:770). **No instance guard anywhere in this handler.**
### 4f. The -500 deathPenalty — the ONLY site (:698-736)
```
if (advancedDamageOn && scenarioRole != 0) // :726
ScoreMessage death_cost(ScoreInflictedMessageID /*0x16*/, ..., type 1,
-scenarioRole->GetSpecialCaseDeathPenalty(), 0.0f, EntityID::Null); // :728-734
Player::ScoreMessageHandler(&death_cost); // :735 DIRECT base call
```
Properties: applied via a DIRECT engine-base call (PLAYER.cpp `currentScore += scoreAward`) — **never dispatched, never on the wire, produces NO `SCORE` matchlog receipt** (only the running total moves; acknowledged at :712-715). The one witness is the **ungated `[deathcost]` DEBUG line** (:716-724) printing `advDmg=/role=/penalty=/scoreBefore=/APPLYING|SKIPPED`. Gates: `advancedDamageOn` — assigned ONLY in the ctor's MASTER branch from `bt_mission->AdvancedDamageOn()` (:2137-2138); on a replicant player copy it is **never assigned** (ctor does not zero it; :1944-1947 zero only console/score/deathPending) [T3: indeterminate there]. `scenarioRole` — bound for both instances with a `Role::Default` fallback (:2066-2084).
### 4g. `DropZoneReplyMessageHandler` (:1743-1920)
`deathCount = 0` on vehicle create (:1798); stale-reply discard when `message->deathCount != deathCount` (:1835-1867 — duplicate deaths that bump deathCount between the re-post and the reply strand the respawn here); `RESPAWN` matchlog (:1906).
### 4h. Scoreboard replication (:2391-2477)
`WriteUpdateRecord` ships killCount/deathTally (:2415-2416); `ReadUpdateRecord` mirrors onto replicants only (:2450-2458), `SBMIRROR` receipt (:2467). **`deathCount` (the respawn-handshake identity) is NOT replicated — only deathTally is** — so replicant-side deathCount writes are never corrected.
## 5. `MechDeathHandler` (game/reconstructed/mechdmg.cpp:1208-1363+)
Nothing score- or count-adjacent: skate detector (:1233-1313), ghost detector (:1315-1342), replicant un-wreck on the mode-9/2 exit edge (:1344-1360). The death-relevant writes in mechdmg.cpp are the `graphicAlarm.SetLevel(9)` sites (:495, :497, :548, :710, :798) which flip `IsMechDestroyed()` wherever damage is applied — including on replicant copies — which is what re-arms the ungated death tail (§1).
## 6. Every site that can run MORE THAN ONCE per death (vs a once-per-event model)
1. **Death tail on replicant victim copies** (mech.cpp:1335-1343): ungated by instance, latched on movementMode which is frozen on replicants for the whole death-record round-trip → **one VehicleDead + one death splash per salvo per peer node**. The exact #150 mechanism, un-fixed for the tail. → explains deathCount 5→8, duplicates 1ms apart / same-ms ×N (each duplicate reroutes to the victim's master and is counted).
2. **VehicleDeadMessageHandler -1 arm has no effective dedup** (btplayer.cpp:546/559/768): the latch is raised and lowered inside one synchronous body, so every queued duplicate increments deathCount/deathTally, debits a life, posts another +5s re-post, and (when its gates pass) applies another death cost.
3. **Death splash multi-application** (mech4.cpp:1382-1428 via mech.cpp:1342): fires from the master's tail AND from every peer replicant's tail (×salvos) → bystander masters take the blast ≥2× → **paired type-1 damage awards** (§3) [T3].
4. **Post-mortem salvos on the wreck**: each still posts Block B+C (mech.cpp:1038 "inflicted-only path"; btplayer.cpp:2646-2690) — by design, but it means received penalties continue after death.
5. **Replicant execution of the 0x16 consumers is unguarded at runtime**: `Verify` is compiled empty (DEBUG_LEVEL=0 → DEBUGOFF.h:42), VehicleDeadMessageHandler has no guard at all, and NTTMGR.cpp:107-149 delivers wire messages to the local copy by entityID with no instance check.
6. **`++sender_owner->killCount` on the victim's replicant player copy** (btplayer.cpp:1206) — bounded by the SBMIRROR correction (banner :2376-2389), kills currently read exact in the field.
## 7. Why the -500 can read "never applies" — as-built observations (mechanism NOT proven here)
The penalty has exactly one producer (§4f) and it is receipt-less: no matchlog row, no wire message — a duplicate-VehicleDead storm shows up as PLAYER_DEAD rows while the penalty leaves only the `[deathcost]` line and the raw total. As-built, the arm CANNOT be reached without also incrementing deathCount (:582 precedes :726 in the same arm), so "deathCount multi-increments AND penalty never applies" requires the :726 gate to fail on every accepted -1 — i.e. field `[deathcost]` lines reading `advDmg=0` or `role=NULL -> SKIPPED`, or the -1 arms executing on player copies whose `advancedDamageOn` was never assigned (§4f). The previous build's -499 eject proof exercised the **type-2 suicide negation** (btplayer.cpp:1192-1195) plus the death cost (46ff8dd message: "1000 - ~999 - 500 = -499"), so the discriminator for build 883 is the ungated `[deathcost]` line and the `[exp] master player ... advDamage=` ctor line (:2141-2145) in the field logs.
## 8. Cross-node routing spine (for the graph)
- `Entity::Dispatch` on a replicant reroutes to the owner host and does NOT execute locally (engine/MUNGA/ENTITY.cpp:235-272).
- Wire arrival: `EntityManager::ReceiveNetworkPacket` posts to the local copy by entityID, handler table via Receive — bypassing the `BTPlayer::Dispatch` type-0 interceptor (btplayer.cpp:1092-1105) and any instance discipline (NTTMGR.cpp:107-149).
- Matchlog receipt map: `DMG` mech.cpp:1290 · `SCORE type=0` btplayer.cpp:1018 · `SCORE type=1/2` :1258 · `PLAYER_DEAD` :601 · `DEAD_NOTIFY` :2724 · `NOCREDIT` :2637 · `SBMIRROR` :2467 · `RESPAWN` :1906 · `PROJ` mech4.cpp:2001 · `SPLASH` mech4.cpp:1349. The death cost has NO tag.

reproduced; it is merely no longer visible).
## Addendum 2026-08-05 — the AUTHENTIC report tail lands (#45/#134)
The kill/damage report sender is no longer the BTPostDamageScore/BTPostKillScore stand-in pair:
`Mech::TakeDamageMessageHandler`'s dark-gap tail (@0x4a02f4-0x4a0890) is reconstructed as
`BTMechPostCombatReports` + `BTMechPostVehicleDead` (btplayer.cpp), dispatching the binary's three
id-0x16 reports (kill to shooter / type-0 wire-fidelity / received to victim) and the BT-extended
0x38 VehicleDead {killed-by player, kill zone} from the victim's handler at the binary's exact
positions. Consequences for this plan:
- KILLS credit path unchanged in shape (victim node -> replicant-player Dispatch reroute ->
killer's master ++killCount) — re-benched cross-node (scorekill.sh: kills=1, award=4.88).
- Suicides now dispatch and the handler negates the award (#134 panic penalty live;
scoreself.sh: type=2 award=-39.00 kills=0).
- Per-hit INFLICTED credit is REMOVED — it never existed in 1995 (@0x4c0200 is bound in no
handler-table entry; scoring = kill awards + received penalties + death costs). SCORE column
behavior changes accordingly; KILLS/DEATHS columns unaffected.
- §Headline-6's wrong-column slip (dual +0x27c increment) remains faithfully reproduced and
replication-masked. The type-1 received report also fixes the console VTVDamaged
points_transfered field (was a Now() misread; it is Round(award), raw disasm @0x4c04a7).

Stall-capable sites are tagged **[S#]**. Evidence tiers: [T0]=our engine source read directly; claims about runtime behavior of third-party code marked [T4].
## Stage A — the HOST marshal (game/glass/btl4console.cpp)
**Arming.** btl4main.cpp:1322-1330 — if `BT_FE_EGG` is set, `BTLocalConsole_Start(fe_egg, BT_FE_PODS, atoi(BT_FE_SECS))` runs. For Steam hosting the menu sets `BT_STEAM_NET=1`, `BT_FE_MYFAKE`, `BT_FE_STEAMMAP` and *falls into the marshal-armed default* (btl4main.cpp:1284-1296). `BTLocalConsole_Start` (btl4console.cpp:588-606) copies the args into `marshalState` and `CreateThread(MarshalThread)`; the handle is closed immediately (:604) — **the marshal thread is never joined by anything**.
**MarshalThread** (btl4console.cpp:434-586), step by step:
1. Read the egg (:440-446). Failure → `MarshalLog("cannot read egg...")` and the thread just returns — the pods sit at WaitingForEgg forever **[S0]** (not tonight's shape, but a stall).
2. Connect every pod in `BT_FE_PODS` order, **self first**, sequentially (:452-482): `ConnectWithRetry(host, port, 60)` (:388-432). The Steam branch calls `BTSteamNet_Connect` which **blocks up to 30 s per attempt** (L4STEAMNET.cpp:595-609) — worst case 60×~31 s ≈ 31 min per pod **[S1]**. Any pod that never answers → `BTFE_RelaunchSelfAndExit("")` — the whole host process aborts the start (:473-476).
3. Egg → every pod (:492-497) via `SendEggChunks` (:334-363). The Winsock branch uses **blocking** `send()` — the marshal's raw sockets are never set FIONBIO (only TCP_NODELAY, :423-425) **[S2]**. Errors surface only as a `-1` chunk count in the log; no retry.
4. `Sleep(20s)`; RunMission #1 to all; `Sleep(4s)`; RunMission #2 to all (:500-512). Send results **ignored**.
5. **The mission clock** (:519-570): `mission_end = GetTickCount() + missionSeconds*1000`; loop drains and discards pod→console traffic (select() for real sockets, a nonblocking `BTSteamNet_Recv` pass for Steam pseudo-sockets :559-569). Note: a Steam connection that dies mid-mission is **invisible** here — `closedByPeer` makes Recv return 0/err and the loop just moves on; nothing logs or repairs it.
6. **StopMission at expiry** (:572-576):
```
MarshalLog("mission clock expired -- StopMission to all pods");
for (int p = 0; p < pod_count; ++p)
SendApplicationMessage(pods[p], StopMissionMessageID);
```
`SendApplicationMessage` (:369-382) writes one 28-byte packet (header clientID=4/ApplicationClientID, msg id 6, ReliableFlag). **One shot per pod. No retry. No acknowledge. The return value is ignored. There is no per-pod success/failure log** — only the single "clock expired" line **[S3 — the silent-drop site]**. Over the Steam seam, `BTSteamNet_Send` (L4STEAMNET.cpp:424-442) returns SOCKET_ERROR if the connection is `closedByPeer` (WSAECONNRESET) or if `SendMessageToConnection` fails (WSAEWOULDBLOCK) — all swallowed. Over raw TCP the blocking `send` could also wedge the loop between pods so *later pods in podList never get their stop* **[S4]** (needs a full send buffer; unlikely for 28 bytes).
7. `Sleep(MissionEndGraceSeconds=8s)` (:577), `MarshalClose` every pod (:578-581), `BTFE_RelaunchSelfAndExit("")` (:583-584) → Stage D. During the 8 s grace the marshal **no longer drains** pod traffic (pods push an immediate console score update in EndingMission — btplayer.cpp:1361-1366).
8. **Host-side race** **[S5]**: the host's *own* pod (self, first in podList) receives StopMission over its loop link, finishes its fade in ~3-4 s, and the MAIN thread reaches the BT_FE_LOOP relaunch (btl4main.cpp:1669-1674) → `ExitProcess` — *while the marshal thread is still inside its 8 s grace sleep*. Whichever thread reaches `ExitProcess(0)` first kills the other mid-flight; if the main thread is slow (long Shutdown) both can pass `CreateProcessW` → two menu children. Nothing serializes the two relaunch paths.
## Stage B — the receiving pod: StopMission → RunMissions returns
**Delivery.** The 28-byte packet is routed by `networkManager->RoutePacket()`, pumped at least once per frame from `Application::ExecuteBackgroundTask` (APP.cpp:771-781; in non-Running states it routes greedily). Steam-carried console bytes are drained lazily by the seam's recv (L4STEAMNET pump is called from the seam entries).
**Handler chain**: `BTL4Application::StopMissionMessageHandler` (game/reconstructed/btl4app.cpp:765-781, @004d3a94 — plasma display off) → `L4Application::` (L4APP.cpp:693-732 — `PilotIllumination(True)` + a LightsOut self-post at +30 s) → `Application::` (APP.cpp:1706-1778):
- `gBTMissionStoppedByConsole = 1` (:1723-1726); if state==RunningMission: `gBTRoundCompleted=1`, launch pends voided (:1733-1739).
- switch (:1746-1777): `StoppingMission` → ignore; `EndingMission`/`AbortingMission` → `Stop()`; **default** → `SetState(EndingMission)`, `networkManager->Mode(ReliableMode)` (:1762), dispatch `Player::MissionEndingMessage` to `GetMissionPlayer()` (:1759-1769); **if the mission player is NULL → `Stop()` immediately** (:1771-1774).
**The fade.** `Player::MissionEndingMessageHandler` (engine/MUNGA/PLAYER.cpp:106-113): `fadeTimeRemaining = 3.0f; ForceUpdate(); SetSimulationState(MissionEndingState)`. **BTPlayer has NO override** — `MESSAGE_ENTRY(BTPlayer, MissionEnding)` (btplayer.cpp:355) resolves to the inherited Player handler; the "fade ForceUpdate site" named in the task brief is PLAYER.cpp:110.
**EVERY condition required to progress from EndingMission to `Stop()`** — the countdown lives ONLY in `Player::ManageApplicationStatus` (PLAYER.cpp:408-476; the MissionEndingState arm :444-472 counts `fadeTimeRemaining -= time_slice` and, at ≤0 with app state EndingMission, dispatches `StopMissionMessage(NullExitCodeID)` back at the application :451-456):
1. A mission player must exist (else Stop() already ran — faster, not a stall).
2. `ManageApplicationStatus` is reached ONLY from the player's active Performance: `Player::PlayerSimulation` (PLAYER.cpp:505, called from `BTPlayer::PlayerSimulation` btplayer.cpp:1329) or `CameraShipSimulation` (PLAYER.cpp:486). **If the mission player's Performance is `HuntForDropZone` (PLAYER.cpp:768 — no MAS call) or `DoNothingOnce` (set at PLAYER.cpp:380 once a dropzone answered the initial hunt; `DoNothingOnce` = `NeverExecute()`, SIMULATE.cpp:484-488 — the entity STOPS EXECUTING ENTIRELY), the fade NEVER counts down and the app sits in EndingMission forever** **[S6 — hard in-engine stall]**. This window exists from mission start until `DropZoneReply` creates the vehicle and sets PlayerSimulation + `AlwaysExecute()` (btplayer.cpp:1771/1780/1784). After that, the reset-based respawn keeps the same Performance through death, so a dead-at-mission-end pilot still fades normally.
3. Fade 3 s of simulated time must elapse; then the re-dispatched StopMission lands in the `EndingMission` case → `Stop()` (APP.cpp:1751-1754) → `executeFrames = False` + `SetState(StoppingMission)` (APP.cpp:818-820).
- There are **no queue-drain gates, no all-entities gates, no peer gates, and no other timers** in this leg.
**Backstop worth knowing**: the solo-clock shim (APP.cpp:674-695) is **ACTIVE in Steam matches** — its only gate is `getenv("BT_RELAY") == 0`, and glass/steam mode does not set BT_RELAY; the glass egg writes `length=` (btl4fe.cpp:277) → `Mission::gameLength > 0` (MISSION.cpp:336-337). So a pod that never receives the marshal's StopMission still self-posts one when its own clock (started at RunningMission entry, APP.cpp:1559) expires. A *lost* StopMission alone therefore should not strand a pod in RunningMission [T0 code-read; runtime unverified].
**RunMissions returning** (engine/MUNGA/APPMGR.cpp:39-273): next frame `ExecuteForeground` returns False (APP.cpp:516-519) → APPMGR calls `application->Shutdown()` (APPMGR.cpp:77-91). `Application::Shutdown` (APP.cpp:828-927): gauge/video/audio `Shutdown()`, viewpoint delete, `interestManager->Shutdown()`, `hostManager->Shutdown()`, `networkManager->Shutdown()` — L4NetworkManager::Shutdown (L4NET.CPP:1296-1411) closes every non-console host via `CloseConnection` = `shutdown(SD_BOTH)` + `BTNetClose` (L4NET.CPP:4658-4659), all nonblocking (engine sockets are FIONBIO throughout, e.g. L4NET.CPP:4554-4558) — deletes the mission, and **returns False** (APP.cpp:925). App is moved to the ended list; the next loop pass finds no apps → `Terminate()` (APP.cpp:934+ — deletes renderers/managers; D3D/DirectSound teardown lives here **[S7, T4]**) → `delete application` → **RunMissions returns** (APPMGR.cpp:128-138). Alternate exit: WM_QUIT (window destroyed) → Terminate + return (APPMGR.cpp:102-115).
## Stage C — after RunMissions returns (game/btl4main.cpp:1618-1684)
- :1619 `"[boot] RunMissions returned (mission loop exited)."` — **the key forensic marker** separating a Stage-B stall from a Stage-C/D hang.
- :1623-1626 `BTProjectilesClearAll()` — static pool scrub, memory-only.
- :1632-1635 `BTRelayUploadMatchLog()` — **relay-only**: gated on `s_relayGameAddrCached` (L4NET.CPP:707-708), a **no-op on Steam nights**. When it does run: bounded 3 s nonblocking connect (L4NET.CPP:738-753), but then an **unbounded blocking SendAll** (L4NET.CPP:770) **[S8, relay only]**.
- :1645-1660 BT_RELAY rejoin — not taken under Steam.
- :1669-1674 `BT_FE_LOOP` set (it always is on menu-launched missions, btl4main.cpp:1248) → `BTFE_RelaunchSelfAndExit("")`.
## Stage D — the exit/relaunch choke point (btl4console.cpp:156-276)
1. `gBTUserRequestedExit` (WM_CLOSE stamp, btl4main.cpp:164-172) → `ExitProcess(0)` directly (:171-181).
2. Storm damper: generation <15 s → `Sleep(5000)` (:193-202).
3. Menu relaunch clears BT_FE_EGG/PODS/SECS/LOOP from the env (:211-217).
4. `CreateProcessW` of the menu child (:259-274). **A CreateProcessW failure is completely silent — no log, no retry — and control still falls to ExitProcess: window closes, no menu appears** **[S9]**.
5. `ExitProcess(0)` (:275) — **the exit-hang site [S10]**. ExitProcess terminates all other threads (the marshal, or the main thread if the marshal got here first) then runs DLL_PROCESS_DETACH serially under the loader lock. **`SteamAPI_Shutdown()` is never called anywhere in the tree** (grep hits only the SDK header, extern/steamworks_sdk_164/public/steam/steam_api.h:107) — so steam_api64/steamclient are detached with live SDR connections and their service threads hard-terminated; a detach-time deadlock there is the standing hypothesis for "BTL4 hang on exit, hosting" [T4 — inference, matches the host being the machine that hosts the most Steam connections]. D3D/driver DLL detach is the sibling candidate [T4].
6. Because every glass-path exit is `ExitProcess`, **CRT atexit/static dtors are skipped** — the RIO dtor's bounded 5 s flush (L4RIO.cpp:1160-1184) and `PCSerialPacket::ShutdownRxThread`'s **unbounded** `WaitForSingleObject(hRxThread, INFINITE)` (L4PCSPAK.cpp:204) **[S11]** only run on the plain `return Exit_Code` path (btl4main.cpp:1683, taken only when BT_FE_LOOP is unset) — and only in serial-RIO builds; glass uses PadRIO which owns no thread (no CreateThread in L4PADRIO.cpp).
## Stage E — is there any all-pods handshake at mission end? NO.
- Start side has three gates: the egg acknowledge (`AcknowledgeEggFileMessage`, L4NET.H:276/424-433), the READY notify (APP.cpp:1466-1470), and the connection gate (L4NET.CPP:1957 comment). **The end has none**: no end-acknowledge message exists (grep across engine/), the marshal reads nothing back after StopMission, and pod teardown never waits on a peer.
- `HostDisconnected` during EndingMission: GameMachineHostType arm just decrements the count and closes (L4NET.CPP:1672-1677) — no state change, no wait. Console loss mid-mission in glass/steam (non-relay, scene presented): the ConsoleHostType arm recreates the console listener and **continues the mission** (L4NET.CPP:1686-1753) — the relay-mode 15 s graceful self-stop (RelayGameDown, L4NET.CPP:2458-2472) does NOT apply outside BT_RELAY.
## Cross-cutting observations relevant to the incidents
- **Thread-safety hole [S12]**: `BTSteamNet_Pump` (SteamAPI_RunCallbacks + unlocked `connections[].ring` writes, L4STEAMNET.cpp:244-306) is invoked from BOTH the marshal thread (via BTSteamNet_Send/Recv/Connect — btl4console.cpp:119-124, 564) and the game thread (seam entries; L4STEAMNET.h:34 documents "game thread"). No lock anywhere. Concurrent RunCallbacks + ring index races are possible on the HOST only (the only process with a marshal) [T0 for the code paths; consequences T4].
- **Frozen-view interpretation** [inference]: a stalled EndingMission does NOT freeze the picture — ExecuteForeground has no EndingMission early-out, the update manager keeps simulating and the renderers keep presenting (APP.cpp:560-565 only overlays pre-run states). A literally static final frame with no menu means the frame loop *stopped* while the window lived: i.e., RunMissions returned (or Terminate/Shutdown hung) and the process then wedged in Stage C/D — most plausibly at ExitProcess [S10] or silent CreateProcessW failure [S9]. Log triage for the frozen machines: `"[boot] RunMissions returned"` present → Stage C/D hang; absent but `StopMission`/plasma-off lines present → Stage B stall ([S6]/[S7]); no stop lines at all → the marshal's send was silently dropped ([S3]) and the solo-clock backstop should then have fired ~launch-skew seconds later — if it didn't, check `length=` in the session egg.

# Task 4 — Steam console-link delivery of StopMission (ticket #163)
## 1. The exact delivery chain for StopMission under Steam
**Dial timing — at GO, once, never again.** The host's mission process arms the marshal thread at boot (`game/btl4main.cpp:1322-1329` → `BTLocalConsole_Start`, `game/glass/btl4console.cpp:588-606`). `MarshalThread` dials EVERY podList entry up front, serially, before anything else: `ConnectWithRetry(host, port, 60)` at `btl4console.cpp:470`. For a fake-IP entry the Steam branch (`btl4console.cpp:391-408`) calls `BTSteamNet_Connect` up to 60 times, 1 s apart; each attempt itself blocks up to 30 s in the SDR handshake wait (`engine/MUNGA_L4/L4STEAMNET.cpp:595-609`) — worst case ~31 min of near-silence before the abort at `btl4console.cpp:473-476` (which aborts the mission start for EVERYONE via relaunch). [T1 — read from our own source]
**Token resolution.** `BTSteamNet_Connect` maps the token IP to a SteamID64 via the `tokens[]` table (`L4STEAMNET.cpp:556-568`), loaded ONCE per process at `BTSteamNet_Install` from env `BT_FE_STEAMMAP` (`L4STEAMNET.cpp:354-384`); port 1501 selects P2P virtual channel 0 = console (`L4STEAMNET.cpp:569`, `TokenConsolePort` at `:67`). The connection is a `ConnectP2P` handle wrapped in a pseudo-SOCKET (`0x5EA0xxxx`, `L4STEAMNET.cpp:93-97`).
**Send path — RunMission and StopMission ride the SAME connection.** Egg chunks (`SendEggChunks`, `btl4console.cpp:334-363`), RunMission #1 (+20 s), RunMission #2 (+4 s), then the marshal holds the clock (`:519-570`) draining pod→console bytes, then StopMission at clock expiry (`:572-576`), 8 s grace, then `MarshalClose` all pods (`:577-581`) and relaunch (`:583-584`). There is **no re-dial, no ack, no health check anywhere** — StopMission depends on the connection dialed at GO still being alive ~10 min later. Wire message: 28-byte packet, clientID=4 (ApplicationClientID), messageID=6 (`StopMissionMessageID`, `btl4console.cpp:75`, per `APP.h:383`), sent via `BTSteamNet_Send` → `SendMessageToConnection(..., k_nSteamNetworkingSend_ReliableNoNagle)` (`L4STEAMNET.cpp:433-435`).
## 2. Every silent-failure point in that chain
1. **Send results are discarded.** `SendApplicationMessage` returns -1 on failure but the return is ignored at all three call sites (`btl4console.cpp:503, 509, 575`). A failed StopMission produces NO log line; the marshal logs only the aggregate "StopMission to all pods" (`:572`) BEFORE sending. [T1]
2. **Send-on-dead-connection is an error only if the death was already noticed.** `BTSteamNet_Send` returns SOCKET_ERROR/WSAECONNRESET only when `closedByPeer` was set by the status callback (`L4STEAMNET.cpp:428-431`), and SOCKET_ERROR/WSAEWOULDBLOCK when `SendMessageToConnection` fails (`:436-440`) — both swallowed by (1). Worse, a reliable send on a dying-but-not-yet-flagged connection returns `k_EResultOK`, buffers the bytes, and they are dropped when the connection is later closed — **undetectable even if (1) were fixed**. [T4 — SDK semantics, not exercised in a bench]
3. **The marshal never learns a console link died mid-match.** The clock-hold drain loop treats Steam recv()==0 (dead: `L4STEAMNET.cpp:459-462`) identically to -1/no-data (`while (BTSteamNet_Recv(...) > 0)`, `btl4console.cpp:564`); the real-socket path likewise ignores `recv`==0 (`:550`). No close callback reaches the marshal; the only trace is the engine-side `[steamnet] connection N closed (…)` line printed from the status callback during a pump (`L4STEAMNET.cpp:219-231`). No reconnect logic exists. [T1]
4. **Mesh/Steam pods have NO console-loss StopMission fallback.** The 15 s self-stop on console loss is RELAY-ONLY (`RelayGameDown`, `engine/MUNGA_L4/L4NET.CPP:2456-2472`). In mesh/steam mode a `ConsoleHostType` disconnect just destroys and re-listens the console host (`L4NET.CPP:1686-1752`, `CreateConsoleHost` at `:885-1023`) — a pod that loses its console link mid-match plays a **forever-mission**: peers time out and freeze as stale replicants — literally "a frozen view of how the game ended" with no menu transition. [T1 code + T2 field, below]
5. **Pump concurrency hazard (host only).** `BTSteamNet_Pump` mutates the global `connections[]`/rings and runs `SteamAPI_RunCallbacks` with zero locking (`L4STEAMNET.cpp:244-306`), and on the HOST it is called concurrently from the marshal thread (via Send/Recv/Connect, e.g. `btl4console.cpp:564`) and the main game thread (via the L4NET seam, `L4NET.CPP:48-96`). Only the host has this exposure. [T1 for the race's existence; T3 for consequences]
6. **Accept is channel-blind.** `BTSteamNet_Accept` ignores which listener polled and dequeues either channel (`L4STEAMNET.cpp:476-501`); the console-host accept path trusts "whatever connects to a console host" (`L4NET.CPP:3876-3894`). Benign so far, but a game-channel dial can be adopted as the console. [T1, no field hits]
7. **Second-round state:** the connection table is per-process (fresh each round — every round is a new process), and mission children get fresh `BT_FE_MYFAKE`/`BT_FE_STEAMMAP` at GO (`btl4main.cpp:1279-1287`). But a MENU relaunch clears only `BT_FE_EGG/PODS/SECS/LOOP` (`btl4console.cpp:211-217`) — menu children carry the PREVIOUS round's token map (visible in the field: relaunched menus log "N roster token(s) incl. self" at boot). The real cross-round asymmetry found is **zombie processes**: a round-N process wedged at exit stays Steam-online into round N+1 (see acaci's ghost lobby seat, below). [T1/T2]
**Receiving side (pod).** `CreateConsoleHost` listens on 1501 (`L4NET.CPP:962-993`) — under Steam the marshal's dial arrives via the P2P channel-0 listen socket, is accepted inside the status callback (`L4STEAMNET.cpp:189-203`), queued, and dequeued by the console host's `BTNetAccept` poll (`L4NET.CPP:3814-3821`); the console host goes OnLine (`:1593-1595`, logs "Connected to ConsoleHost at <token .1>:1501"). Marshal-side death is detected only by `BTNetRecv` returning 0 (or WSAECONNRESET→0) during `CheckBuffers` (`L4NET.CPP:3989-4019`). At mission end the pod does NOT close the console link — teardown explicitly keeps the console host (`L4NET.CPP:1367-1370`); the MARSHAL closes it 8 s after StopMission (`btl4console.cpp:577-581`), which the pod handles as a normal console disconnect + re-listen. So there is no close-while-the-other-side-needs-it on the pod side. [T1]
## 3. Field evidence (scratchpad/night15, six logs; frozen = santo/MS-FIREFLY, acaci/ZEUS; Lynx has NO log)
**StopMission WAS delivered to every logged pod in both incident rounds.** Every mission session on santo ends with the full clean tail `[boot] RunMissions returned` + `[fe] mission over -- relaunching the menu` (14/14, e.g. santo:57956-57957 for the round ending 21:40:50 — the 21:41 incident round — and santo:201693 for the round ending 22:47:21 — the 22:48 incident round). Michael (d:153225-153226) and Dave (a: tail before 218096) likewise ended the 22:47 round cleanly. **No `[steamnet]` close, no ConsoleHost disconnect, no PEER_DOWN anomaly at either incident round-end on any logged machine.** The freeze on the logged machines happened AFTER the last log line of a clean in-process mission end — i.e., in the relaunch/exit seam, NOT in Stop delivery. [T2]
**But genuine console-link death happened that night — twice — and its signature matches the reported symptom exactly.** Mid-round, all pods lost BOTH links to the host token (.1) with `[steamnet] connection N closed (Timeout; remote problem. Rx age server 12-21s ...)` followed by `Disconnected from ConsoleHost at 169.254.77.1:1501`: eleng f:22366-22372 (+ a second episode f:50374-50455) and the santo(e:35887-35922)/rajel(b:20340-20416) round (same round; rajel's clock is -3 h). After the loss the pod keeps simulating with no console and no fallback (finding 4): peers ghost out (`[ghost] replicant 5:29 has received NO update records for 601 frames`, f:~22434) and the mission never ends — each player eventually closed the window by hand (`[marshal] window closed by the user -- exiting for real`, e:36012, f:22510). The "Timeout; remote problem" reason means the HOST process went silent mid-round (crash/wedge, not graceful close) — the host is the machine with the marshal-thread pump race (finding 5). [T2; the race attribution is T3]
**The frozen machines' actual signatures:**
- **santo ~21:41:** round ended cleanly 21:40:50 (e:57957); the menu child (pid 28112, e:57959-57966) booted fully, auto-joined the lobby within 1 s, and received GO normally at 21:43:10 (mission child pid 31404, `relaunched generation`, e:57967). The 2m20s hole between a clean end and the next GO, with a healthy-but-invisible menu, fits a wedged mission-parent window sitting frozen on top of the live menu (the foreground-handoff problem this code already documents, `btl4console.cpp:262-271`). [T2 logs; interpretation T3]
- **acaci 22:48:** ZEUS's log goes SILENT at 22:12:38 — the post-round menu child (pid 29344, c:213897-213900) printed exactly 3 boot lines and never reached `[steamnet] up`, which for a relaunched child is unconditional ~1 s after boot (`BT_STEAM_NET` is inherited; boot-time install at `btl4main.cpp:1306-1316`). It hung at/before `SteamAPI_Init` (`L4STEAMNET.cpp:337`). acaci never played again (file mtime 23:18, nothing after 22:12:38) — **acaci was NOT in the 22:37-22:47 round at all**; yet acaci's SteamID (76561198064247614) still appears as token .2 in the 22:47 lobby map on santo/Michael (e:201702, d:153233) — a ghost lobby seat held by the wedged process. [T2; "hung at SteamAPI_Init" is T3 — the alternative, a user-kill inside the ~1 s boot window, is implausible given the same machine repeated it]
- The same 3-line pre-SteamAPI_Init signature ends EVERY machine's log (Dave 22:47:22 — the exact incident round end, a:218096-218099; eleng 21:47:21; rajel 20:25:37; Michael 23:25:36; santo 23:25:37) and appears mid-night followed by ~1-2 min manual-restart gaps (Dave 20:31:52→20:32:40 a:31170; acaci 21:07:11→21:09:13 c:60457). The relaunch/exit seam wedges routinely; nobody calls `SteamAPI_Shutdown` anywhere (grep: SDK headers only), and every round-end exits via `ExitProcess` from `BTFE_RelaunchSelfAndExit` (`btl4console.cpp:275`) — on the HOST from the marshal thread while the main thread is mid-teardown (`btl4console.cpp:583-584`), matching Lynx's "hang on exit, hosting". [T2 signatures; ExitProcess/DLL-detach mechanism is T4]
## 4. Bottom line for #163
The StopMission delivery chain is a single unmonitored 10-minute-old connection per pod with at least four fully silent failure modes (send-result discarded; error mapped then discarded; reliable-buffer drop; dead-vs-empty indistinguishable in the drain loop) and no mesh-mode fallback on the pod — a real design hole, and the night's two host-death rounds show exactly what its failure looks like (orphaned forever-mission, frozen peers). **However, for the two ticketed incidents the field logs exonerate delivery:** every logged pod received Stop and ended its mission in-process; the freeze and the exit hang live in the round-end relaunch/exit seam (ExitProcess without Steam shutdown; menu children hanging pre-SteamAPI_Init; ghost lobby seats from wedged processes), on which the marshal's host-side thread-kill-at-clock-expiry piles extra risk for the host machine.

**CRITICAL CORRECTION TO THE TICKET'S PREMISE [T1]:** `matchlog_20260810_213656_20476.txt` (ALIA, local 21:36) and `matchlog_20260810_223651_12120.txt` (DESKTOP-QR9VPJQ, local 22:36) are **the SAME mission** — the 22:36 ET round — recorded on two machines whose clocks differ by exactly 1h. Proof: identical MISSION run instant (A line 22: `MISSION … w=21:37:21.041 st=4 run` vs B line 22: `w=22:37:20.047`), identical terminal events (A line ~1319: `DEATH victim=2:20 … pos=-27.5,0.0,144.2` + final `SBMIRROR player=8:1 kills=4 deaths=2 wasKills=3 wasDeaths=2`; B lines 1816-1818: same death at `pos=-27.6,0.0,144.2`, same SBMIRROR). Matchlogs are written per-machine (each pod keeps one), confirmed by dev-bench pairs in `scratchpad/night15/mlbak/` (two matchlogs per bench round). There is **no matchlog for the 21:41-incident round** in the staged set. Lynx DID host the 22:36 round (host token .1=…659597127 in the round's map, ALIA line 172106) — and in fact hosted **every round from ET 21:08 through 22:47**, including BOTH incident rounds (santo maps at 36020, 46238, 57965, 68589, 101519, 124366, 156700 all show .1=…659597127).
## 1. The mission-end ladder as it appears in these logs
There are **no** 'EndingMission'/'StopMission'/state-name lines in this build's day logs. The observed healthy end shape (every clean round, every machine) is:
```
[mission] solo game clock expired (600s|1200s) -- ending the mission
[score] gauge read / ~RankAndScore: I think my score is N
[lamp] 0xNN <- 0x0 (×41, cockpit lamps off)
SVGA16::~SVGA16: pixel management statistics + 4 lines
[glasswin] destroy entry #1 windows=0
[glasswin] destroy entry #2 windows=0
[boot] RunMissions returned (mission loop exited).
[fe] mission over -- relaunching the menu <=== LAST LINE the process ever logs
===== BT411 SESSION ... ===== (the relaunched MENU process, new pid)
```
(e.g. santo 57904→57959). ~50-60 lines, wall time ≤3s (the menu header lands the same/next second as the computed 600s expiry). After `[fe] mission over` the process calls `BTFE_RelaunchSelfAndExit("")` → `CreateProcessW` + `ExitProcess(0)` (game/btl4main.cpp:1671-1673, game/glass/btl4console.cpp:157-275) — **everything after the `[fe]` line is unlogged by construction**.
## 2. Incident A — ~21:41 ET, santo (MS-FIREFLY) frozen
**Round:** ET 21:30→21:40:50, Lynx-hosted, 6 players (santo 46238 map: Lynx.1, eleng.2, acaci.3, santo.4, Dave.5, rajel.6), 600s clock. Michael not in it.
**santo's end sequence is textbook-clean and on time [T1]:**
- 57887-57903: normal in-mission ticks (santo idle: `speedDemand=0`, alive — targeting active; the last nearby deaths are replicants 7:4 at 54956 and 6:4 at 57832, NOT santo).
- 57904 `[mission] solo game clock expired (600s)` → 57906 `~RankAndScore: I think my score is 2686` → lamps → 57948 `SVGA16::~SVGA16` → 57954-5 glasswin destroys → 57956 `RunMissions returned` → 57957 `[fe] mission over -- relaunching the menu` → **57959 new MENU session at 21:40:50** (same second as everyone else, below). The log never goes silent mid-ladder and never keeps ticking past the end. (No `[glassperf]` beats exist on this machine — the tag appears only in Dave's and Michael's logs.)
- **Recovery:** the relaunched menu was alive immediately — 57963-57965 it joined the NEXT round's lobby (token .7); santo was playing again at **21:43:10 ET** (57967), ≈2m20s after the freeze report. No manual cold restart visible.
**Same-round healthy comparison (identical ladder shapes, same wall second):**
| machine | EXPIRED line | menu-header line | menu local time (→ET) |
|---|---|---|---|
| santo (frozen) | 57904 | 57959 | 21:40:50 |
| eleng | 73366 | 73424 | 20:40:50 (21:40:50) |
| acaci | 11986 | 12045 | 20:40:37 (≈21:40:50) |
| Dave | 75044 | 75126 | 21:40:54 |
| rajel | 44983 | 45041 | 18:40:50 (21:40:50) |
**Conclusion [inference, flagged]:** the freeze left NO trace in santo's day log. Everything up to and including the menu relaunch executed on time; the only unlogged window is the old glass process's `ExitProcess(0)` path after `[fe]`. The "frozen view of how the game ended" is consistent with the OLD process hanging after spawning the menu — its last rendered frame stays on the fullscreen/plasma window on top while the new menu opens BEHIND (the build even logs `[marshal] foreground handoff denied -- the next window may open behind` for this Z-order hazard, e.g. santo 46239; emit site btl4console.cpp:267-271).
## 3. Incident B — ~22:48 ET, acaci (ZEUS) + Lynx (host) frozen
**Round:** ET 22:36:51→22:47:2x, Lynx-hosted, 8 players (map ALIA 172106: Lynx.1, acaci.2, …976435895.3, santo.4, eleng.5, Michael.6, Dave.7, rajel.8), GO at 22:37:20.0 (matchlog B line 22), 600s ⇒ nominal expiry 22:47:20 ET.
**acaci (ZEUS) end sequence [T1]** — clean, but with the night's most interesting receipt:
- 159680 `[wreck] replicant 2:20 entered wreck state … at (-27.6352,144.223)` — **Lynx's mech dying at 22:47:15.6**, the same death both matchlogs end on.
- **159890 `[steamnet] connection 1 closed (closed)` + 159892 `Disconnected from GameMachineHost at 169.254.77.1:1502` — the HOST (Lynx) dropped ZEUS's game link BEFORE ZEUS's own clock expired** (ZEUS's 600s clock ran ~3-10s later than the pack because its RunMission receipt timing; it was the last machine still in-mission).
- 159894 `EXPIRED (600s)` → 159909/159911 second disconnect (`169.254.77.5:1502` = eleng, tearing down in parallel) → 159970 `RunMissions returned` → 159971 `[fe]` → **159973 menu session 21:47:11 local (≈22:47:24 ET)**.
- **Recovery:** menu joined the 22:52-round lobby immediately (159979); acaci played the 22:52 ET round (159981, glass 21:52:09 local) — recovered ≤5 min; quit for the night cleanly at 23:14:36 ET (`lastrun_steam_acaci_ZEUS_8.txt` line 29: `[2026-08-10 22:14:36] clean exit: player quit from the menu`; his day log's final 3-line menu stub at 213897 is the systemic buffered-tail loss described in §6, not a wedge).
**Same-round healthy machines:** Michael 153171→153227 (menu 22:47:20), santo 201637→201695 (22:47:21), rajel 192406→192463 (19:47:21=22:47:21), eleng 216583→216639 (21:47:21=22:47:21), Dave 218029→218096 (22:47:22). All within 0-4s of nominal expiry, identical ladders. eleng then quit for the night at 22:47:48 ET (lastrun line 47) — unaffected.
**Lynx (host, no day log):** his own matchlog (B) stops at 1818 `SBMIRROR … w=22:47:15.805` — his own death (`PLAYER_DEAD … player=2:1 deaths=10` at 22:47:15.642, B line ~1813), **5.6s before expiry, respawn never recorded** — and contains no mission-end receipt. He reported "BTL4 hang on exit, hosting" + Task Manager; he is absent from both later lobbies (22:52 map santo 201701; 23:15 map santo 255102) — **never returned**. The pre-expiry link close seen on ZEUS (`(closed)`, i.e. orderly close, not timeout) proves Lynx's process DID start its teardown (its clock expired first); the hang happened later in his exit path [inference].
## 4. Did StopMission ever arrive? (Task 4)
**No — on any machine, at any round, all night [T1]:**
- `grep StopMission` over all six day logs (≈90MB): **0 hits**.
- Every mission end on every machine is the LOCAL fallback: `[mission] solo game clock expired (Ns) -- ending the mission` (14 on santo, 10 on eleng, 8 on acaci, etc.).
- The marshal's only sends all night are launches: `[marshal] RunMission #1 sent to N pod(s)` / `RunMission #2 sent -- mission running; clock Ns` (Dave 766/899, 13401/13588, 16085/16289, 23146/23304, 32151/32319, 50684/50831; rajel 19145/19269; Michael 615/733, 209577/209723). No `[marshal] StopMission` line ever.
- Consequence: rounds end as N independent local expiries skewed by RunMission-delivery jitter (0-13s spread observed), and the host tears its links down whenever ITS clock fires — peers see `Disconnected from GameMachineHost … :1502` pre-expiry when their clock is late (ZEUS 159890 in incident B; also Dave 118701 & 141778, Michael 13749, eleng 60403 & 84435 — all Lynx-hosted rounds).
- Corroborating shape from earlier the same night: when a HOST vanished mid-round (Dave closed his hosting window at 20:21:27 and 21:06:28 ET), peers did NOT transition — they sat in-mission until SteamNetworkingSockets timed out (`Timeout; remote problem. Rx age server 11-21s`: rajel 20340-20416, santo 35887-35922, eleng 22366-22440 & 50374-50455) and each user had to close the window (`RunMissions returned` + `[marshal] window closed by the user`). There is no host-loss or console-driven end path under Steam in the field [T1].
## 5. Matchlog tails vs bench baseline (Task 3)
- Field matchlogs (both machines, incident-B round) end mid-combat with NO end receipt: A ends `SBMIRROR … w=21:47:16.821`, B ends `SBMIRROR … w=22:47:15.805`. Neither contains any `st=6`/stop/`PEER_DOWN` record; the only MISSION line each is `st=4 run`.
- Dev-bench matchlogs (mlbak/, builds 874-885) normally end with **`PEER_DOWN t=… host=1 type=3`** (the console/relay link closing at teardown) — e.g. matchlog_20260811_005558_2240.txt last line, matchlog_20260810_102334_9548.txt last line.
- So both field matchlogs lost their teardown tail. Since ALIA demonstrably transitioned cleanly, the missing tail is NOT diagnostic of the hang; the likely mechanism is the `ExitProcess(0)` relaunch path discarding the matchlog's unflushed stdio buffer (btl4console.cpp:275) [T3].
## 6. Systemic log-tail artifact (don't misread it)
Every collected day log ends with a fresh MENU session header + exactly 3 `[boot]` lines and nothing more (Dave 22:47:22, eleng 21:47:21, rajel 20:25:37, Michael 23:25:36, acaci 22:12:38, santo 23:25:37). The lastrun files prove these menus ran fine and exited cleanly minutes later (ZEUS quit 22:14:36 local; ALIA quit 21:47:48 local; santo's final sessions rotated into `steam_20260810.1.log` — not collected; Dave's post-22:47 activity, including hosting the 22:52 ET round per map token .1=…022091594, is likewise missing from the collected file). The `[boot]` lines carry explicit `std::flush` (btl4main.cpp:1605-1619); the later `[steamnet]`/`[lobby]` lines evidently don't survive the quit path's buffer loss. Truncated final menu stub ≠ wedge.
## 7. Healthy baseline round (Task 1 control): ET 22:22:36 → 22:33:11, Lynx-hosted, 8 players
| machine | glass session (local) | EXPIRED line | menu line | menu local (→ET) |
|---|---|---|---|---|
| santo | 22:22:36 (124368) | 156637 | 156694 | 22:33:11 |
| Michael | 22:22:36 (74169) | 107656 | 107712 | 22:33:10 |
| Dave | 22:22:37 (141879) | 173829 | 173890 | 22:33:11 |
| eleng | 21:22:36 (140157) | 172042 | 172100 | 21:33:11 (22:33:11) |
| acaci | 21:22:23 (83362) | 115098 | 115152 | 21:32:57 (≈22:33:10) |
| rajel | 19:22:36 (113680) | 146649 | 146702 | 19:33:11 (22:33:11) |
Identical ~55-line ladders, all six menus stamped within 1s. The incident-round ladders of the frozen machines are line-for-line indistinguishable from this baseline.
## 8. Synthesis (clearly marked inference where noted)
1. [T1] The in-log mission-end ladder COMPLETED normally and on time on every frozen machine; the freeze lives entirely in the unlogged post-`[fe]` exit path (`BTFE_RelaunchSelfAndExit` → `ExitProcess(0)`, btl4console.cpp:275).
2. [Inference] "Frozen view of the ended mission" = the old glass process hung inside `ExitProcess` (classic DLL-detach/terminated-thread deadlock territory: SNS threads, D3D, the plasma-window thread) with its last frame still on screen, while the already-spawned menu opened BEHIND it (`AllowSetForegroundWindow` hazard logged at btl4console.cpp:269). Task Manager kill of the OLD pid clears it — exactly Lynx's report.
3. [T1] Both incidents happened in Lynx-hosted rounds; Lynx's own machine hung at exit in incident B while hosting (7 console links + relay + marshal to unwind). In incident B, Lynx's teardown began BEFORE the last peer's expiry (orderly `(closed)` on ZEUS 159890) and then hung.
4. [T1] StopMission is not part of this build's field behavior — every end is the local solo clock; the marshal only launches. Host death mid-round strands every peer in-mission until manual window close (three occurrences 20:08-21:07 ET).
5. [T2] Lynx died in-game 5.6s before the clock and his respawn never appears before the end; acaci and santo were alive at their freezes — a death-at-end race is NOT the common factor across the three frozen instances.
6. Recovery: santo ≈2m20s (auto-relaunch worked; next round 21:43:10 ET); acaci ≈5 min (next round 22:52 ET, quit cleanly 23:14:36 ET); Lynx: killed via Task Manager, never rejoined.
==============================================================================
# Ticket #163 / #156 — TASK 3: The binary's end-of-mission truth
Scope: the 1995 `BTL4OPT.EXE` end ladder, read from `reference/decomp/all/part_*.c` + the T0 WinTesla MUNGA source the port compiles against, with constants byte-read from the image (`scratchpad/rdva.py`) and one raw disasm (`tools/disas2.py`). Everything is [T1] (decompiled + cross-checked against T0/raw bytes) unless tagged.
## 0. Headline answer
**The 1995 end sequence is EVENT → TIME → EVENT, and the only timed leg runs inside the mission player's own simulation tick.** Console `StopMission` (event) puts the app in `EndingMission` (state 6) and dispatches `MissionEnding` to the mission player; the player then counts a **3.0-second** `fadeTimeRemaining` down **in player-Performance time** (`ManageApplicationStatus` @0x42df8c); at ≤0 it self-dispatches a **second `StopMissionMessage`** (event) which, arriving at state 6, calls `Application::Stop()` @0x44e6c0 → `executeFrames=0` → the mission loop unwinds. **Nothing in the ladder waits on the visual fade** — the fog fade renderable (@0x45447c) is a passive video watcher. **The ladder CAN stall in exactly two binary-grounded ways:** (a) StopMission #1 never arrives — the mission runs forever (1995's console owned the clock; the pod never stops itself — `context/multiplayer.md:639-641`); (b) the mission player's Performance never executes while in `MissionEndingState` — then `fadeTimeRemaining` never decrements, StopMission #2 is never dispatched, and the app parks in `EndingMission` FOREVER. Once the countdown completes, StopMission #2 is a **direct synchronous `application->Dispatch`** (PLAYER.cpp:454-455; @0x42df8c line 740) — it cannot be lost in transit.
## 1. The Application state machine's EndingMission arm (binary addresses)
State enum (T0 `engine/MUNGA/APP.h:188-202`): Initializing=0, WaitingForEgg=1, LoadingMission=2, WaitingForLaunch=3, LaunchingMission=4, RunningMission=5, **EndingMission=6**, StoppingMission=7, Suspending=8, Resuming=9, Aborting=10, CreatingMission=11. App state read as `*(app+0x88)`; the `StateIndicator` sits at app+0x74 with current state at indicator+0x14, and `SetState` = `FUN_0041bbd8` @0x41bbd8 (part_002.c:5510) — which also **pings three watcher chains** (indicator+0x18/+0x2c/+0x40, vtbl+0x14 notify) — this is how the fade renderable learns of state flips.
Binary Application TU (part_007.c:3090-3810):
- **`FUN_0044eeb4` @0x44eeb4 = `Application::StopMissionMessageHandler`** (part_007.c:3698-3737): state 7 → ignore; state 6 or 10 → `Stop()` (@0x44e6c0) — this is the SECOND arrival; default → `SetState(6)`, and if `missionPlayer(app+0x14)` non-null: `networkManager->Mode(0=ReliableMode)` (vtbl+0x30 on app+0x20, part_007.c:3721 == T0 APP.cpp:1762) then dispatch **`Player::MissionEndingMessage {size 0x1c, id 0x19}`** to the player; if NO mission player → `Stop()` directly. Matches T0 APP.cpp:1705-1778 exactly.
- **`FUN_0044ef4c` @0x44ef4c = AbortMissionMessageHandler** — same shape, `SetState(10)`, no ReliableMode switch.
- **`FUN_0044e6c0` @0x44e6c0 = `Application::Stop()`**: `executeFrames(app+0x70)=0`; flush DEBUG stream; `SetState(7)`. (T0 APP.cpp:797-821.)
- **`FUN_0044e488` @0x44e488 = `Application::ExecuteForeground`** (part_007.c:3138-3176): returns 0 immediately when `executeFrames==0`; at state 5 recomputes `secondsRemainingInGame(app+0x58) = mission->length(+0xe0) − (Now−gameStarted(+0x5c))/tps`; final return is `executeFrames && !Exit_Code` where **Exit_Code = `DAT_004efc98`**. **There is NO pod-side action when the clock hits 0** — app+0x58 is display-only; the stop was the console's job.
- **`FUN_0044e6e8` @0x44e6e8 = base `Application::Shutdown`** (part_007.c:3239-3278): gauge/video/audio renderer `Shutdown+UnlinkFromEntity` (+0x4c/+0x48/+0x44), delete viewpointEntity (+0x6c), interestManager/hostManager/networkManager shutdown, delete `currentMission(+0xC8)`, then **`executeFrames=1; SetState(1=WaitingForEgg); return 0`**.
- Other rungs for contrast: CheckLoad `@0x44ebec` (2→3, and if **no console host** (`FUN_00429078(app+0x2c)`) self-launches RunMission — the console-less path), RunMission `@0x44ecdc` (3→4 + dispatch **MissionStarting id 0x18** to player; 4→5 + `gameStarted=Now()`; else Fail @APP.CPP:0x609 — the port's launch/load-race crash site), Suspend `@0x44ed88` (5→8 + dispatch id 0x19 — suspend ALSO rides the player MissionEnding fade), Resume `@0x44ee10`, KeyCommand `@0x44efd8` ('&'=0x26 → `Exit_Code=1` + `Stop()`).
**There is NO app-side timer in the end arm.** The only end-sequence time constant anywhere is the player's 3.0 s fade (plus the fade renderable's cosmetic 1.0 s, §3). No mission-review display period exists at the app level; the ranking window is a separate per-player display driver (§below).
**Ranking-window behavior at end** — `FUN_0042eb38` @0x42eb38 (part_004.c:1387-1426, called from PlayerSimulation/CameraShipSimulation): at states **6/7 the window flag (player+0x224) is forced 0 (hidden)**; while `secondsRemainingInGame > 30.0` (`_DAT_0042ec2c`=30.0, byte-read) it runs a periodic show/hide machine (+0x228/+0x22c/+0x230/+0x234); at ≤30 s it pins the flag to 1 (solid on). So the authentic end was: standings solid for the final 30 s, then StopMission → **ranking hidden + 1 s fade to black**. (The camera-seat DIRECTOR.cpp:107 additionally shows its ranking during EndingMission — different display, camera seat only.)
**Crucial executability fact [T0]:** `Entity::Execute` (ENTITY.cpp:556-558, quoted in `context/reconstruction-gotchas.md §29:920-934`) calls `PerformAndWatch` only in `RunningMission || EndingMission || IsPreRunnable()` — so the world (and the player's fade countdown) KEEPS TICKING during state 6, and stops at state 7. A screen showing a *frozen last frame* therefore means the app got PAST state 6 (Stop() ran, `executeFrames=0`, renderers no longer execute) but the process never finished Shutdown/relaunch — whereas a player *stuck in state 6* would see a live, still-simulating world that never returns to menu. (Relevance flag for #163 triage, [T4 inference]: post-`RunMissions` in the modern port comes the matchlog-upload dial + relaunch (`context/multiplayer.md:110`, `:541-545`) — a blocking network call there matches "frozen final frame + hang on exit".)
## 2. The Player handlers @0x4bfc20 / @0x4bfbe8
Base handlers (part_004.c:409-430):
- **`FUN_0042d9c0` @0x42d9c0 = base `Player::MissionStartingMessageHandler`**: `fadeTimeRemaining(+0x1F4) = 3.0f`; `SetSimulationState(3=MissionStartingState)`.
- **`FUN_0042d9e0` @0x42d9e0 = base `Player::MissionEndingMessageHandler`**: `fadeTimeRemaining = 3.0f`; **`ForceUpdate` (`+0x18 |= 1`)** — this ships the final player update record (score) under the just-switched reliable mode; `SetSimulationState(4=MissionEndingState)`. Neither touches the Performance pointer or `simulationFlags`.
**BT overrides** (part_013.c:18556-18588; raw disasm of @0x4bfc20 via `tools/disas2.py` this session):
- **`FUN_004bfbe8` @0x4bfbe8 = BTPlayer::MissionStarting**: base @0x42d9c0, then `if (app->state==4 /*LaunchingMission*/ && !(this+0x29 & 0x40 /*NonScoringPlayerBit*/)) currentScore(+0x1c8) = 1000.0f` — the manual's "+1000 starting the game" seed (port: `game/reconstructed/btplayer.cpp:788-806`).
- **`FUN_004bfc20` @0x4bfc20 = BTPlayer::MissionEnding** — full body:
1. base @0x42d9e0 (fade 3.0 + ForceUpdate + state 4);
2. **`this+0x288 −= Round(15.0f × DAT_0052140c + 0.5)`** — recovered from raw bytes @0x4bfc3b-0x4bfc52 (`fld 15.0f @0x4bfca4; fmul [0x52140c]; fadd 0.5f @0x4bfca8; call __ftol@0x4dcd94; sub [ebx+0x288],eax`): it **rewinds the 15-second console score-total clock by exactly one period**, so the next PlayerSimulation tick immediately pushes the FINAL total score to the console (see §5). The old export dropped the x87 operand (`FUN_004dcd94()` rendered argless — the §19 gotcha); now pinned.
3. `if (app->state == 8 /*SuspendingMission*/ && playerVehicle(+0x1fc) IsDerivedFrom Mech (tag 0x50bdb4))` → `FUN_0049fb74(mech, &DAT_00524b38, 1)` (= `Mech::Reset`, per the KB respawn chain — `context/decomp-reference.md` "Respawn SIM path"; the argument blob `DAT_00524b38` semantics unverified [T4]) + `ForceUpdate`. So the operator SUSPEND path resets the vehicle; the normal state-6 path does NOT.
- **No score finalization, no fade rendering, no waiting happens in this handler** — it is fire-and-forget bookkeeping; the actual fade/countdown/exit all run elsewhere.
**The countdown** — **`FUN_0042df8c` @0x42df8c = `Player::ManageApplicationStatus`** (part_004.c:706-752; == T0 PLAYER.cpp:408-476): state 3: `fade −= dt`; at ≤0 (`_DAT_0042e0dc`=0.0) → state 2 (VehicleTranslocated) + dispatch RunMission (app state 4) / Resume (state 9). **State 4 (MissionEnding): `fade −= dt`; at ≤0 → app state 6 → dispatch `StopMissionMessage(exit 0)` (ctor @0x44f5d0); state 8 → SuspendMission; state 10 → AbortMission.** Called every tick from `Player::PlayerSimulation` @0x42e100 and `Player::CameraShipSimulation` @0x42e0e0 (part_004.c:756-781) — both flavors complete the ladder. (KB nit: `btplayer.cpp:1329` cites base PlayerSimulation as `FUN_0042e168`; @0x42e168 is only the vehicle-position-copy tail — the full base is @0x42e100.)
**When can the countdown not run?** `Simulation::DoNothingOnce` = `NeverExecute()` = `simulationFlags |= DontExecuteFlag` (SIMULATE.cpp:484-488, SIMULATE.h:167-206). In the 1995 binary the master player is parked on DoNothingOnce only **pre-first-spawn** (`Player::HuntForDropZone` @0x42ddcc sets the pmf `PTR_FUN_004e67fc` at part_004.c:669 once the drop zone is found, until DropZoneReply re-arms). The BT death cycle does NOT park it: **`FUN_004c05c4` @0x4c05c4 = BTPlayer::VehicleDead** (part_013.c:19064-19156) contains **no SetPerformance/simulationFlags writes** — a mid-mission-dead player still ticks PlayerSimulation, so a StopMission arriving during a death window still completes the fade in 1995. Its first line is the state-4 gate (`this+0x40==4 → return`): once MissionEnding, all death traffic is swallowed. Also in the -1 arm: deaths dual-increment (+0x280), console **MechKilled id 8** via ctor @0x4c18cc gated `suppressConsole(+0x258)==0`, objectiveMech(+0x284)=killer's vehicle, lives check `role(+0x208)->returnFromDeath(+0x28) < 1` → post Mech id 0x18 (ClearBurningState) to the wreck at +10 s and NO respawn re-post; else re-post VehicleDead to self at +5.0 s (`@0x4c0830`=5.0f, byte-read); then the straight-line death cost gated `advancedDamageOn(+0x264)` via direct call to base ScoreMessageHandler @0x42da20.
## 3. THE FADE (ticket #156)
**Mechanism: a fog-color/fog-range animation on the main view — `POVStartEndRenderable`** (T0 `engine/MUNGA_L4/L4VIDRND.cpp:2126-2394`, binary ctor **`FUN_00454394` @0x454394**, Execute **`FUN_0045447c` @0x45447c**, part_007.c:8468-8606). Not a palette fade, not a gauge overlay, not the warp machinery.
- **Built for the LOCAL (master) player only** by the video builder **`FUN_004d0774` @0x4d0774** (part_014.c:10673-10693): classID 0xBDA (BTPlayer): replicant (`(entity+0x28 & 0xc)==4`) → translocation-warp renderable @0x458d2c; **master → alloc 0x50 → `FUN_00454394(entity, Watcher=2, mainView, mainZone, deathZone, trigger, fogRGB, fogNear/Far, 3, 4)`**. The trigger = the player's **SimulationState attribute** (`FUN_0041bf44(entity,1)`), i.e. the same `StateIndicator` the MissionStarting/Ending handlers write; start state **3** = MissionStartingState, end state **4** = MissionEndingState.
- **State machine** (@0x45447c; myState at +0x1c, timer +0x3c, trigger state read at `trigger+0x14`): 0 WaitForStart → on trigger==3: fog snapped to WHITE (1,1,1) with near/far 0.01/0.05 (screen fully fogged = white flash), AddDynamicRenderable; 1 FlashScreen: hold **0.1 s** (`@0x454740`); 2 FadeIn: lerp fog color/ranges back over **1.0 s** (`@0x454744`); 3 MissionRunning: wait for trigger==4 → 4 FadeOut: fog color × percent-left → black, ranges collapse to 0.01/0.05 (`@0x45474c/0x454750`), over **1.0 s in the binary** — note the WinTesla source's `FADE_OUT_TIME (0.5f)` (L4VIDRND.cpp:2150) is a later edit; the shipped 1995 constant is 1.0 (the same `@0x454744` is reused as the fade-out duration at part_007.c:8584); at expiry → back to state 0 + RemoveDynamicRenderable.
- **What advances it:** the renderer's frame clock (`GetCurrentFrameTime`), NOT the player sim — once state 4 is set it completes even if the player sim is dormant. **What would happen if it never completed: nothing.** The ladder never reads the renderable; `ManageApplicationStatus` is the sole gatekeeper. The fade-out (1.0 s) simply fits inside the 3.0 s window; the pod then sat on a black screen ~2 s before teardown.
- **Why the port has no fade (#156 root cause):** the builder call exists (`game/reconstructed/btl4vid.cpp:311-315`, states 3/4 passed), but **`BTPOVStartEndRenderable`'s ctor is an empty stub — `game/reconstructed/btstubs.cpp:339-342`** — it never registers with the video renderer or the state dial. The white mission-start flash is missing for the same reason. All the plumbing it needs (SetState watcher ping @0x41bbd8, fog style/limits on the D3D renderer) already exists in the port.
## 4. RunMissions exit + what the 1995 pod did next
- **Exit condition** (T0 `engine/MUNGA/APPMGR.cpp:39-161`): `RunMissions` loops foreground/packet-route/background passes; when `application->ExecuteForeground(...)` returns False (binary: `executeFrames==0 || Exit_Code(DAT_004efc98)` — @0x44e488) it calls `application->Shutdown(n)`; **Shutdown returning False removes the app from `runningApplications`, and with no apps left RunMissions Terminates them and RETURNS.**
- **1995: the pod did NOT exit** — the L4 (pod) application overrides Shutdown: **`FUN_0047c560` @0x47c560** (part_010.c:2805-2820) = base Shutdown @0x44e6e8 (which re-arms `executeFrames=1` + `SetState(WaitingForEgg)`) then **`return (Exit_Code==0 && app+0xd4==0) ? 1 : 0`** — i.e. the app STAYS in the manager and the pod parks in WaitingForEgg for the console's next egg (the between-rounds attract wait). RunMissions only returned on the '&' keystroke (Exit_Code, @0x44efd8) or the `app+0xd4` shutdown latch (set by the two-phase handler **@0x47c2c4** — first receipt latches +0xd4 and re-posts, second receipt tears down; a console-initiated pod shutdown [T3 on its exact message id]).
- The modern build diverges deliberately: T0 APP.cpp:922-926 replaced the original `return !Exit_Code` with a hard `return False` (`#if 0` preserved in-source), and `engine/MUNGA_L4/L4APP.cpp` has **no** Shutdown override — so every mission end exits RunMissions, then btl4main uploads the matchlog and BT_FE_LOOP relaunches the menu (`context/multiplayer.md:110,541-545`).
## 5. The end-of-mission pod↔console handshake
All pod→console, fire-and-forget over the console link (clientID 5 = ConsoleClientID); **the ladder never waits for any console reply**. Names from the surviving original `game/original/BT/BTCNSL.CPP` (cnslmsgs.cpp) + T0 `engine/MUNGA/CONSOLE.h:11-18`:
| When | Message {size, id} | Binary ctor / site |
|---|---|---|
| Every 10 s AND immediately once app state == **6** | score **DELTA** flush: self-dispatch ScoreUpdate {0x20, 0x1a} → the +0x278 delta cell is sent then **zeroed** | **`FUN_004c083c` @0x4c083c** (part_013.c:19160-19192): `10.0(@0x4c08fc) <= (this+0x10 − this+0x28c)/tps \|\| app+0x88==6`; port analog `btplayer.cpp:1361-1427` |
| Every **15 s** while state 5 or 6; forced immediately at MissionEnding by the @0x4bfc20 clock rewind | **ConsolePlayerMechScoreUpdate** (running TOTAL, from +0x1c8) {0x14, id 9} | ctor **@0x4c18f4**; send site part_013.c:19269-19279 (`_DAT_004c0bc0`=15.0, clock at +0x288) |
| Once, when `fadeTimeRemaining ≤ 1.5` in MissionEndingState (i.e. **halfway through the 3 s fade**, while the link is guaranteed still up), one-shot latch +0x254 | state 6: **ConsoleApplicationEndMissionMessage {0x14, id 7} {host, Round(score)}** (added 10/05/95 per BTCNSL.CPP:10); otherwise (abort/suspend): **ConsoleApplicationAbortMissionMessage {0x10, id 0xb}** | **BTPlayer::PlayerSimulation `FUN_004c0904` @0x4c0904**, block part_013.c:19251-19268, Tell string `"Sending EndMission..."` @0x5132d7; ctors @0x42998c / @0x4299b4 |
| On death (any time) | **ConsolePlayerMechKilled** {0x14, id 8} {victim, killer} | ctor @0x4c18cc, sent from VehicleDead @0x4c05c4 (part_013.c:19110-19114), suppressed after eject via +0x258 |
| On eject | DeathWithoutHonor (id 5) | `FUN_004c198c` (KB: decomp-reference EJECT cluster) |
| (team variants) | TeamScoreUpdate {0x14, 0xd} @0x4c191c; TeamEndMission {0x1c, 0xe} @0x4299d8 | |
Plus two non-console end actions: **`networkManager->Mode(ReliableMode)`** at StopMission #1 (@0x44eeb4/T0 APP.cpp:1762) and the base MissionEnding **ForceUpdate** shipping the final player record to peers. Also note part_013.c:19280-19282: while state 5 **or 6**, the player record is re-dirtied (`+0x18 |= 1`) whenever none has shipped for 1.0 s (`_DAT_004c0bc4`) — a 1995 1 Hz player-record keepalive that keeps running through the ending window.
## 6. Stall matrix (the ticket's question, binary-grounded)
| Leg | Driven by | Can it stall? |
|---|---|---|
| StopMission #1 → state 6 | console event over the console link | YES — if it never arrives the mission runs forever (1995 design; modern relay adds the +15 s RelayGameDown fallback, multiplayer.md:519-521). World stays LIVE (not frozen). |
| state 6 → StopMission #2 | **3.0 s of MISSION-PLAYER SIM TIME** (@0x42df8c) | YES — iff the mission player's Performance stops executing while in MissionEndingState (DontExecuteFlag latched, or its Performance never calls ManageApplicationStatus). In 1995 the only such window is pre-first-spawn (HuntForDropZone→DoNothingOnce, part_004.c:669). Result: app parks in state 6 forever — world keeps ticking (ENTITY.cpp:556-558), ranking window hidden (@0x42eb38), never returns to menu. |
| StopMission #2 → Stop() | direct synchronous Dispatch | NO (cannot be lost). |
| Stop() → RunMissions return | next foreground pass: ExecuteForeground→0, then Shutdown (synchronous renderer/network/mission teardown @0x44e6e8) | Only if a Shutdown callee BLOCKS (e.g. a network shutdown on a dead transport). From Stop() onward the screen is a FROZEN LAST FRAME (renderers no longer execute) — the shape #163 describes. |
| visual fade | renderer frame clock, passive watcher | irrelevant — nothing waits on it; in the port it's a stub anyway (btstubs.cpp:339-342). |

BT411 -- ALL OPEN TRACKER ISSUES (59), SORTED FOR PLAYTESTERS
Updated 2026-08-10 (evening) -- after Oracle's full annotated sweep, which
closed 35 issues. Thank you Oracle: that is what this list is for.
=============================================================================
HOW TO REPORT: drop a line in Discord with the issue number and PASS /
FAIL / what you saw. Screenshots and rough times help; logs get collected
as usual.
=============================================================================
-----------------------------------------------------------------------------
A. FIXED -- PLEASE VERIFY (headliners first: new fixes fielded THIS build)
-----------------------------------------------------------------------------
#149 Glass cockpit stutter / hitching ** HEADLINER **
First fielded build with the fix. Glass users -- especially Oracle:
mission load and play should feel smooth again (repaints now skip
windows whose gauges did not change).
#150 Double kill credit (one kill counted twice) ** HEADLINER **
First fielded build with the fix (868's double-kills were pre-fix).
TEST: kill someone with a missile volley -- scoreboard +1, not +2.
#69 "Sunder V1" renamed to DENKOU
TEST: vehicle picker shows Denkou -- era witnesses, confirm spelling.
#71 Closing the Plasma window lost it until restart
TEST: X the plasma window -- it minimizes to the taskbar; click restores.
#25 Gamepad turn profile (stick X could not turn the mech)
TEST: RajelAran -- bind an axis to "Turn" in content\bindings.txt.
#27 Autocannon/Gauss dealt the wrong damage type
Oracle asked for a RETEST before closing: ballistics should feel/score
like solid shot (no blast splash).
#38 Mech colors reverted on respawn
TEST: custom paint, die, respawn -- colors stay.
#39 Controls were live before the game screen appeared
TEST: mash fire during load -- nothing happens until the scene shows.
#41 (David/Auric) launcher killed before it could run -- forensics armed
TEST: if join.bat ever fails again, send content\lastrun_join.txt.
#56 MFD buttons drift away from where they are drawn
TEST: alt-tab / focus changes mid-round -- buttons stay aligned.
#147 Range caret vanished for the session (ticks stayed)
Monitoring: if it happens, the log traps the culprit -- just report it.
#158 (Sauron) could not move after respawn until throttle cycled
TEST when it happens: does cycling the throttle free you?
YES -> the #146 release mechanic (expected). NO -> map + spawn spot.
-----------------------------------------------------------------------------
B. OPEN -- HELP US REPRODUCE / NARROW (what to note when it happens)
-----------------------------------------------------------------------------
#24 Controller hat/look view sticks (recovers after wiggling)
#37 Mech torso appears BACKWARDS to other players (transient)
#74 8BitDo gamepad works solo, dead in Steam MP (VexUbiquity)
#102 Owens: full-throttle run -> hold reverse = animation/audio hang
REPRO known (exterior cam, savannah); self-clears on a torso twist.
#125 Peers do not see the FIRST destroyed-zone graphic (2nd hit shows it)
#126 Peer weapon fire invisible AND silent from some positions
#128 Ramming terrain = INSTANT coolant leak -- Oracle re-confirms STILL LIVE
#130 Vulture "skating" (gliding without walk animation)
#132 (Conn Man) persistent yellow line on the HUD in every mech
#135 Coolant leak with NO flashing annunciators -- Oracle re-confirms LIVE
#136 A SHUT leaking loop starts/stops leaking with COMPONENT toggles
(Oracle marked "Clarify" -- one more description pass requested.)
#143 One panel hit -> smoke erupts from MULTIPLE places at once
#153 Basic-mode elevation limit only applies after cycling modes (fix pending)
#154 Generator Out warning fires on the WRONG EDGE (at recovery, not trip)
Refined by Oracle: the stuck-forever gen did NOT reproduce; era rule =
gens return at HALF-cooled (red bar portion gone). Threshold audit due.
#155 PANIC lit: Eng + Weapon MFD banks dead; Score/Radar/Coolant stay live
(Oracle mapped the exact bank split; #50 closed into this ticket.
Flicker half = authentic. Next: is the bank capture authentic too?)
#159 (Conn Man) lag during drops -- missiles / fire exploding in empty space
NOTE: shooter + target + rough time; match receipts measure the rest.
#160 Pod cab: RIO axis dropouts + boot wedges (hardware investigation)
Cab-side only. Bounded-write hardening is in this build; the cage
hardware work continues with Nick.
-----------------------------------------------------------------------------
C. STILL-OPEN ERA QUESTIONS
-----------------------------------------------------------------------------
#103 Mech-to-mech RAM: armor damage or internals only? (Oracle: don't know;
Lynx / Ronin / Draco -- your call. Binary does internals-only.)
#133 Generator X-out on the MFD: Oracle recalls an X "under certain
circumstances" -- WHICH circumstances? (shutdown / overheat / destroyed)
ALSO (#152 rider): did Mid/Adv auto-recentre the torso in the pod, or only
Basic? (Oracle: don't know. Binary says: no auto-recentre.)
-----------------------------------------------------------------------------
D. DESIGN CALLS -- group opinions wanted
-----------------------------------------------------------------------------
#151 Panic eject costs -499: verified REAL 1995 scoring (your death scored
as suicide + death penalty). Keep authentic, or house-rule a flat cost?
#23 Non-glass screen layout: Oracle proposes widescreen-aware sizing --
world view wider + taller, moved up, allowed to overlap the radar.
Opinions welcome before anyone prototypes it.
#77 Resizable Secondary/Radar window (touch-panel cockpits). Want it?
-----------------------------------------------------------------------------
E. KNOWN GAPS -- confirmed and on the list, no need to re-report
-----------------------------------------------------------------------------
#49 Radar/map does not draw the arena WALL geometry
#76 Glass layout save/restore rework (some windows not saved)
#83 INCOMING MISSILE alarm not implemented yet
#90 Flames/smoke from serious damage: less than the original (tuning)
#104 Mad Dog "NARC 15" label: NARC postdates our 4.10 binary (Oracle: added
in a late 4.x release; zero NARC in our decomp) -- content rename due.
#105 Sensor damage effects: Oracle's era spec captured (HUD flicker/loss,
radar loss) -- implementation pending.
#111 Peers see a dying mech's blue warp bubble (should see explosion only)
#112 AFC rounds shotgun across zones (should land as one projectile)
#113 LRM burn/hit state lasts too long
#115 Hot box / target select not connected (Oracle era note: hotbox was a
STANDARD-mode feature; absent in Expert -- gating to reconcile)
#121 Sensor HEAT has no consequences yet
#123 Searchlight: the visible LIGHT + night-fog swap still to come
#145 IR "predator vision": decode done, display not implemented
#156 Fade-to-black at mission end not happening
-----------------------------------------------------------------------------
F. INTERNAL ENGINEERING BACKLOG (nothing to test)
-----------------------------------------------------------------------------
#14 Glass panel unreconstructed button handler backlog (census)
#17 Cavern upper-butte halves lack a collision stream (authenticity TBD)
#21 Weapon recharge arc dark after eng-page use (symptom trail -> #62)
#28 Confirm the vital-subsystem-crit death path can fire (machinery in)
#30 Weapon "unavailable" (level-7) display verification + accessor cleanup
#63 PlayerStatus reads raw 1995 offsets (databinding trap, dormant)
#64 damageZone shadow field (half-fixed; consequences disarmed)
#65 HandleMessage non-virtual across 10 classes (latent dispatch trap)
#72 BTLoadPump swallows WM_QUIT during load (latent)
#107 Destroyed HeatSink annunciates nothing (no lamp for condition 0)
#117 KB note: per-chassis cockpit bounce was deliberate (Ronin) -- FYI

TICKET #128 — PORT AS-BUILT CHAIN (terrain ram/scrape -> instant coolant leak)
=========================================================================
STAGE 1 — THE EMITTER (physical collision -> TakeDamage dispatch)
=========================================================================
The [crashdmg] print lives in Mech::AuthenticGroundAndCollide, game/reconstructed/mech4.cpp:8526. Full path:
1a. Per frame, the master mech (only movers with a collisionAssistant run the collision half — replicants bail at mech4.cpp:8427-8428) fetches contacts: GetCurrentCollisions() (mech4.cpp:8431), then Mover::ProcessCollisionList(cols, dt, old_position, &dmg) (mech4.cpp:8450-8452). `Damage dmg` is stack-constructed: Damage::Damage (engine/MUNGA/DAMAGE.cpp:35-45) sets damageAmount=0, burstCount=1; **damageType is NOT initialized by the ctor** — it is stamped Damage::CollisionDamageType(0) inside Mover::ProcessCollisionList at engine/MUNGA/MOVER.cpp:1228, and the accumulated `total_damage` across the frame's contacts is written at MOVER.cpp:1350.
1b. Per contact, the engine calls the virtual Mech::ProcessCollision (mech4.cpp:8754-8883, binary @004abb40). It restores frameEntryWorldVelocity first (mech4.cpp:8777 — PORT ADDITION, "COLLISION-DAMAGE ECONOMY GUARD": prevents multi-solid frames compounding StaticBounce reflections; commented as fixing 4x-40x over-pricing), runs the BoxedSolid resolver, then prices via Mover::StaticBounce (mech4.cpp:8796-8797 -> engine/MUNGA/MOVER.cpp:1432-1528).
1c. THE AMOUNT FORMULA (engine T0, MOVER.cpp:1527): `return -0.0005 * (vn*vp) * moverMass`, where impact = worldLinearVelocity·normal; damage is 0 if impact > 0 (separating, MOVER.cpp:1465-1469). vn/vp are the reflected normal/parallel components scaled by (1+elasticity). Constants: 0.0005 (MOVER.cpp:1527); minimumBounceSpeed only ZEROES elasticity when -impact <= bounce_min*dt (MOVER.cpp:1470-1473) — **there is NO minimum-speed gate on the damage amount itself; any closing contact prices > 0**. Measured economy (context/combat-damage.md:413-415): raw ≈ 600·v² for a head-on mech (59221 @ |v|=9.94; moverMass is tonnage-scale 60000-90000).
1d. OWNER CLASSIFICATION (mech4.cpp:8815-8866): a Mover owner -> mech-vs-mech dispatch via BTDispatchCollisionDamage, edge-gated by ramLastVictim/ramContactLinger 0.35s (mech4.cpp:8837-8846 — PORT ADDITION, explicit one-bump-one-hit; the binary's edge was implicit in its bounce). A CulturalIcon owner -> crunch dispatch + 0.00123f walk-through sentinel. **Plain UnscalableTerrain owners (ground/hills/cliffs/canyon walls) match NEITHER branch — their StaticBounce damage stands with NO edge gate whatsoever** (comment mech4.cpp:8656-8658).
1e. THE TERRAIN CRASH RESPONSE (mech4.cpp:8485-8537): if dmg.damageAmount > 0.0f, the frame is fully rejected (velocity zeroed 8487, position restored 8488), [crashdmg] prints (8526-8531, always-on), and an Entity::TakeDamageMessage{inflictor=SELF, zone=-1, dmg VERBATIM} is dispatched at OUR OWN mech (8532-8536, binary @4aa984-4aaab4). Stamps: damageType=0 (from MOVER.cpp:1228), burstCount=1 (Damage ctor), amount=raw StaticBounce kinetic price.
1f. FIRE RATE: per frame while scraping. The freshBlock hysteresis was deliberately REMOVED (pricing audit 2026-07-31; comment mech4.cpp:8560-8565). The only natural pacing is the knockdown: iv2 > 40 (i.e. |v| > ~6.3 u/s, const @0x4ab184, mech4.cpp:8540) binds the bmp clip whose cycleSpeed 0 collapses velocity. **Below iv2=40 there is no knockdown, so a sustained scrape with a closing normal component re-prices and re-dispatches EVERY FRAME at full drive speed** (the gait re-derives velocity each frame — context/combat-damage.md:427-431 documents exactly this hazard for the mech-vs-mech case, which got the ramContactLinger fix; terrain never did).
=========================================================================
STAGE 2 — THE DISTRIBUTOR (Mech::DistributeCollisionDamage)
=========================================================================
Divert site: mech.cpp:1160-1164 — `if (message->damageData.damageType == 0) { DistributeCollisionDamage(&message->damageData); goto death_tail; }` (binary @0x4a0368; never reaches the zone/armor loop; jumps to the death tail, not return — mech.cpp:1149-1158).
Full body mech.cpp:980-1028 (binary FUN_0049ffcc):
- GATE (mech.cpp:982-985): `player = GetPlayerLink()` (mech+0x190); return if null or !BTPlayerAdvancedDamageOn(player). The bridge (btplayer.cpp:2201-2204) reads **advancedDamageOn2 = the SECOND cell this[0x9a] = +0x268** — it DOES reproduce the binary's +0x268 gate (@0x49ffde) [T1]. Both cells are stamped together at btplayer.cpp:2131 from btMission->advancedDamageOn (mission+0xf0, the egg "advancedDamage" technician flag). NOTE [inference, T3]: commit 3545056 ("steam eggs stamp the host's advancedDamage mission-wide — penalty was silently off for every steam match") means this gate only recently began PASSING in steam matches — plausibly why two testers suddenly report the leak as new.
- SCALE (mech.cpp:987-990): `scale = ((2000/moverMass) / (100·0.27777779)²) / (1 − elasticity²)` — constants match binary (tbyte @0x4a0148 = 1/3.6, 2000f @0x4a0154; mass +0x20c, elasticity +0x244). ≈ 4.5e-5 at 60t/e=0.2 (measured, context/combat-damage.md:1124). Note the mass CANCELS against StaticBounce's ·mass, so scaled amount ≈ (vn·vp)/(771.6·(1−e²)) — mass-independent.
- FREE FLOOR (mech.cpp:991-992): scaled < 0.5f -> return (taps free; @0x4a003c). **This floor IS the effective "minimum speed": measured 2.55 pts at 9.6 u/s -> the floor clears at |v| ≈ 4.25 u/s head-on.** Between ~4.3 and ~6.3 u/s a scrape prices 0.5-1.2 pts per frame with no knockdown pacing (see 1f).
- SUB-HITS (mech.cpp:994-997): n = Round(amount·2), min 1; each sub-hit = amount/n (~0.5 pts each).
- SELECTION (mech.cpp:1007-1025): per sub-hit, one [0,1) roll walks the full subsystem roster accumulating collisionCriticalHitWeight (+0x10C, authored per subsystem resource "CollisionCriticalHitWeight", mechsub.cpp:200/652); eligibility = IsDerivedFrom HeatSink-family(GUID 0x50e590) / Gyroscope(0x50fdc0) / Torso(0x510b08). Measured weights (scratchpad/SESSION_HANDOFF_20260801.md:39): HeatSinkBank 0.3 / Gyro 0.35 / Torso 0.25 / Myomers 0.35. Un-won rolls land nowhere (weights un-normalized — faithful). Winner takes the sub-hit via MechSubsystem::ApplyDamageAndMeasure (mechsub.cpp:459-481, binary @0x4ac07c = the audited FUN_004ac07c) -> MechSubsystem::TakeDamage (mechsub.cpp:513-538, @0x4ac0bc) -> the subsystem's PRIVATE DamageZone::TakeDamage: `damageLevel += amount × damageScale[0]` (engine DAMAGE.cpp:391), scale = points-normalized from authored damageTypePoints/weaponDamagePoints (mechsub.cpp:220-237).
- Subsystems per event: up to n (one per sub-hit); a full-run terrain crash (~2.6 pts) = n=5 sub-hits, so up to 5 subsystem rattles per impact.
MASTER GATING: **DistributeCollisionDamage is NOT master-gated.** The #150 gate (mech.cpp:1288) covers only the score-report tail and the #162 gate (mech.cpp:1372-1373) only the death tail; the type-0 divert at mech.cpp:1160 runs BEFORE both, on any instance. The port deliberately applies damage on replicants for visual response (comment mech.cpp:1276-1282; binary asserted replicants OUT of this handler entirely, part_012.c:14613-14616). So the shooter-side ram dispatch at the victim's local REPLICANT (BTDispatchCollisionDamage, mech4.cpp:8845; victim->Dispatch, mech4.cpp:8717 — also streamed cross-pod to the master per task #47, messmgr.cpp:348) runs the divert on the replicant too, subject only to the replicant's playerLink/advancedDamageOn2 gate. The TERRAIN self-crash emitter itself is master-only (replicants have no collisionAssistant, mech4.cpp:8427), so #128's chain is master-side.
=========================================================================
STAGE 3 — THE LEAK ONSET (subsystem damage -> coolant leak)
=========================================================================
HeatSink::UpdateCoolant, game/reconstructed/heat.cpp:1061-1118 (binary @004adbf8):
- `coolantDraw = ownZone->damageLevel × heatLoad` (heat.cpp:1078-1080; reads the subsystem's OWN private DamageZone.damageLevel — the exact cell the rattle sub-hit raised).
- Floors/thresholds (heat.cpp:70-80, byte-verified): draw < 0.0025 -> zeroed (_DAT_0050e3d8); coolantActive flips ON at draw > 0.003 (_DAT_0050e3d4), OFF below 0.0025 — hysteresis (heat.cpp:1110-1117).
- coolantActive IS the leak: it feeds the ReportLeak attribute (heat.cpp:489, all 19 authored leak watchers -> the "warning: coolant leak" voice) and coolantDraw is published as CoolantMassLeakRate (heat.cpp:481) -> the cockpit LeakGauge (btl4gau2.cpp:984/1008). Coolant then drains at coolantDraw/s with central-tank top-up via DrawCoolant (heat.cpp:1095-1105).
- heatLoad = 15-sample filtered average of 0.002×temperature×coolantLevel, clamped [0,1] (heat.cpp:70-72, 886-926); typical running value ~0.6 (radiatedHeat ~300 band comment heat.cpp:60-61).
- THE THRESHOLD: leak springs when damageLevel > 0.003/heatLoad ≈ 0.005 at typical load. A single 0.5-pt sub-hit raises the private zone by 0.5×damageScale[0] ≈ 0.5/points — for any plausible authored points (10-50) that is 0.01-0.05, i.e. **an ORDER OF MAGNITUDE above the leak threshold. One free-floor-clearing sub-hit landing on ANY heat-family subsystem = instant audible leak, deterministically.** And since Myomers is heat-family (weight 0.35) alongside HeatSinkBank/Condensers/Generator/Reservoir, most of the eligible weight IS heat-family; with n=5 sub-hits at run speed, at least one landing heat-family is near-certain — matching "every single time".
- Design intent note: heat.cpp:1070-1072 states the AUTHENTIC behavior — draw rises only as the heat subsystem takes battle damage; there is no repair, so the leak persists once lit (clears only when heatLoad drops enough to cross the 0.0025 OFF hysteresis — the "warning coo-- war--" oscillation, heat.cpp:876-879).
=========================================================================
GUESSES / STAND-INS / PORT DEVIATIONS in the chain (admitted in comments)
=========================================================================
1. mech4.cpp:8868-8873 [T3]: InitialHit(1) vs Slide(2) contact-state split — the two collision floats @0x240/0x244 are fieldAt() STUBS returning 0; port always accumulates InitialHit. (Audio-only; not damage.)
2. mech4.cpp:8777 + 8436-8441: frameEntryWorldVelocity restore — PORT ADDITION (economy guard), not in the binary (its ground was a heightfield probe, never a collision-list entry).
3. mech4.cpp:8837-8846: ramContactLinger 0.35s one-bump gate — PORT ADDITION, mech-vs-mech ONLY; the binary's edge was implicit in its bounce separation. **Terrain self-damage got no equivalent gate — the per-frame scrape pricing is the port's own emergent behavior**, bounded in the binary by its velocity-reversing bounce.
4. mech4.cpp:8566-8567: knockdown mid-clip rebind guard — admitted "cheap belt-and-braces port addition"; the binary has no rebind guard.
5. mech4.cpp:8508-8510 TODO: throttleState = fall-surface material not forwarded (binary (**[mech+0x2f8])+0x24) — payload nicety, unmapped.
6. mech.cpp:984: `player == 0` null guard is a port guard (binary reads +0x268 through the link; the audit says the link is always live there).
7. mech.cpp:1086-1089 [T3]: lastInflictingID write site is a reconstruction guess (binary write site not located).
8. Replicant damage application (mech.cpp:1276-1282) — deliberate port deviation from the 1995 replicant assertion; consequence: the divert/distributor can run on replicant copies (see master-gating above).
9. Cross-pod TakeDamage streaming (task #47, messmgr.cpp:348) — port addition; in the 1995 pod, ram damage was network-inert (context/combat-damage.md:416-419).
10. Subsystem private-zone damageScale values are authored content (res+0x30/+0x44, mechsub.cpp:220-237) — I did not extract the per-subsystem numbers; the "0.01-0.05 per 0.5-pt hit" figure is inference from the points normalization, not a measured value.
==============================================================================
# Task 4 — Reconstruction archaeology of the collision→coolant-leak chain (#128)
## A. TIMELINE — how the chain reached its current shape
**2026-07-05 (7b7d465, initial commit).** WinTesla engine baseline. The engine already contained the collision PRICING: `Mover::StaticBounce` returns `-0.0005 * (vn·vp) * moverMass` (C:/git/bt411/engine/MUNGA/MOVER.cpp:1527) and `Mover::ProcessCollisionList` stamps `damage->damageType = Damage::CollisionDamageType` (MOVER.cpp:1228) and accumulates the total into the Damage record. The engine RETURNS the Damage to the caller — it never dispatches it. So the pricing formula is ENGINE truth [T0], not a port invention, and the crash-response FORWARDING is game-side policy.
**2026-07-08 (2af401e) — first collision damage dispatch.** `BTDispatchCollisionDamage` added (mech-vs-mech + cultural-icon crunch), unblocked by the STEP-6 cylinder hit-location work. Terrain explicitly did NOT damage: "Terrain (walls/hills) matches neither branch, so it still BLOCKS without damage (faithful to the binary)" — a claim later falsified (the terrain self-damage was hiding in an export gap). The self-TakeDamage on a blocking hit was left as a marked "DEFERRED" note in the response policy (mech4.cpp ProcessCollision header, still visible at mech4.cpp:8660-8664). Era symptom: "grinding has no effect" was structurally true — wall crashes cost nothing.
**2026-07-12 (bb795e2) — the ram one-shot + first guard.** First live MP wave found StaticBounce reflections compounding 4-40x across multi-solid frames ("a walking bump one-shot a pristine mech for 112,375 pts"). Fix: `frameEntryWorldVelocity` per-contact restore (port guard for an engine-facility drift, gotcha #16) + `Mech::Reset` motion zeroing. Both are port additions [T3-justified], still in place (mech4.cpp:8436-8441).
**2026-07-13 (065c114) — the ×1e-3 normalization [T3, admitted guess].** "Port normalizes x1e-3 to the point economy [T3]" — an INVENTED scale patched in because raw kinetic amounts (~59,000 pts @10 m/s, moverMass ~60-90k) were hitting the victim's ARMOR zones directly (the divert did not exist yet). Also added `ramLastVictim`/`ramContactLinger` contact-edge (one-bump-one-hit, 0.35s re-arm) — a port invention [T3] compensating for the port's kinematic gait velocity never reading as "separating" the way the binary's bounce-reversed physics velocity did. The contact edge SURVIVES today (mech4.cpp:8444-8449).
**2026-07-30 (9c83a46, #82 ROOT FIX) — terrain crash SELF-damage recovered.** The wall-grind "knockdown storm / skating" report decomposed; the missing piece was recovered from the EXPORT GAP by raw disasm (scratchpad/night6/gap_4a9770.txt, binary @4aa89f-4aaab4): fallDirection = worldToLocal(damageForce), fallScalar = -(fallDirection·localVelocity), and a self-dispatched `TakeDamageMessage{0x64, zone=-1, engine Damage verbatim}`. This closed the old DEFERRED note — terrain crashes now hurt, per the 1995 binary [T1 raw disasm]. The `[crashdmg]` log line was added here as the pricing arbiter ("run 14 field report: 'tapped a wall and died instantly', so the forwarded amount is suspect vs binary" — mech4.cpp:8523-8531). Also FALSIFIED en route: the action-request-flags drive-suppressor theory. A port-only mid-clip rebind guard kept as "belt-and-braces" (mech4.cpp:8560-8567).
**2026-07-30 (14ff351, #83) — the COLLISION DIVERT, hours later.** The self-damage immediately exposed its missing second half: raw kinetic figures were falling into the WEAPON zone/armor loop ("tapped a wall and died instantly"). Recovered @0x4a0368 (hub) → FUN_0049ffcc (distributor, also an export-gap fn, raw disasm scratchpad/night6/gap_49ffcc.txt): gate on victimPlayer advancedDamage copy 2 (+0x268, @0x49ffde); scale = (2000/moverMass)/(100km/h)^2/(1-e²) (tbyte 1/3.6 @0x4a0148, 2000f @0x4a0154); <0.5 FREE (@0x4a015c); Round(2×) sub-hits on random HeatSink-family/Gyro/Torso subsystems via cumulative collisionCriticalHitWeight (+0x10C) and ApplyDamageAndMeasure (@0x4ac07c). All byte-anchored [T1] (mech.cpp:960-1028). Bridges (BTHeatSinkFamily/BTGyroscopeFamily/BTTorsoFamily, BTPlayerAdvancedDamageOn) added same commit.
**2026-07-31 (37dd7f9) — collision-pricing audit, two REMOVALS of port inventions.** (A) The 0.4s `gBlockCooldown` contact-hysteresis (a port stand-in) DELETED — it had suppressed the knockdown while contact held, letting the drive re-slam at full price every frame → the night-7 SAURON grind death (110 priced frames @|v|~34.7). Binary needs no guard (crash threshold @0x4ab178 = 0.0 read from the exe). (B) The ×1e-3 normalization DELETED — it double-normalized against the divert's ~4e-5 scale, making victim-side rams a no-op. Raw dispatch restored [T1 @part_012:15324]. Bench: scratchpad/night7/mp_rampricing.sh — 150s wall push = 0 rattle 0 deaths; 9.6 m/s ram = 2.55 pts rattle. KB swept: the "moverMass ≈1.3e6" figure corrected to measured 60-90k tonnage scale (an earlier mis-attribution).
**2026-07-31 (a8a0042, #88) — coolant leaks BECOME POSSIBLE.** Until this commit a leak was STRUCTURALLY IMPOSSIBLE: the MechSubsystem ctor filled only its re-declared SHADOW damageZone (#64, gotcha #1), so `HeatSink::UpdateCoolant`'s engine-member read was NULL forever. Fix aliased the engine base member; from this build on, `coolantDraw = zoneDamage × heatLoad` prices live. Same commit documents the authored collision-rattle weights extracted from BTL4.RES [T1]: HeatSinkBank 0.30 / Gyro 0.35 / Torso 0.25 / Myomers 0.35, Condenser+Reservoir 0 for collisions. NOTE the coupling: #83 (rattle) and #88 (leaks) went live ONE DAY apart — the terrain-ram→leak behavior could not have been observed before 2026-07-31 builds.
**2026-07-31 (839b040) — night-8: the divert declared "matches the field".** KB records: "RAM damage: the binary's internal-only collision divert MATCHES what players observe (gyro/myomer damage, coolant leak, NO armor damage, grinding inert). May be working as intended; awaiting a player ruling. Gitea #103." (context/open-questions.md:1023-1028). I.e. ram→coolant-leak was seen on night-8 and DISPOSED AS AUTHENTIC-SHAPED, with only the armor question left open.
**2026-08-02 (night-10, build 716) — #128 filed.** "Ramming terrain = INSTANT coolant leak (4 for 4 that night). NOTE: still 100%? speed at impact; which terrain." (first tester handout, git show bf04e1c:docs/OPEN_ISSUES_FOR_TESTERS.txt:126-127). #125-#130 appear as "carried" in scratchpad/SESSION_HANDOFF_20260803.md:51. **No commit has ever addressed #128** (git -S/--grep sweeps find only the two handout commits).
**2026-08-05 (91bd286) — divert tail corrected.** The #83 block had shipped with an early `return`; the binary actually JUMPS TO THE DEATH TAIL (raw disasm @0x4a0375: jmp 0x4a07b5) — fixed to `goto death_tail` so a rattle death still posts VehicleDead; no score reports on this path (mech.cpp:1149-1164).
**2026-08-10 (night-15) — Oracle re-confirms:** "#128 Fail - Happens every single time I collide with terrain at speed, needs to be at some mimimum speed. Confirmed." (scratchpad/night15/OPEN_ISSUES_20260810_commentary2.txt:151). Handout regenerated (40c3594) with "#128 ... Oracle re-confirms STILL LIVE".
**2026-08-11 (3545056, #162) — advancedDamage stamping.** "Steam eggs stamp the host's advancedDamage mission-wide (penalty was silently off for every steam match)". Night-14 steam logs show advDmg MIXED across players (docs/KD_CHAIN_AUDIT_20260811.md:194: 8 APPLYING all advDmg=1, 32 SKIPPED all advDmg=0). Since the rattle gate is the SECOND advancedDamage cell (+0x268), set from the same mission egg copy (btplayer.cpp:2128-2132: `advancedDamageOn = advancedDamageOn2 = bt_mission->AdvancedDamageOn()`), the collision rattle was per-node-egg-dependent in steam matches before build 885 and is now uniformly the host's setting.
## B. Provenance verdict per element
- **Pricing ([crashdmg] amount):** ENGINE (WinTesla MOVER.cpp StaticBounce), shipped 1995 — NOT invented [T0]. The [crashdmg] fields (mass, |v|, force) are diagnostics only.
- **Terrain crash→TakeDamage forwarding:** 1995 BT game code @4aa89f-4aaab4, recovered by raw disasm 2026-07-30 [T1]. OUR addition history: absent (pre-07-30) → present raw. The engine never forwarded; the game always did.
- **The divert + DistributeCollisionDamage:** byte-anchored reconstruction [T1], constants read from the exe.
- **Rattle target weights:** authored data (BTL4.RES) [T1].
- **Leak pricing (`coolantDraw = zoneDamage × heatLoad`, floor 0.0025 / ON 0.003):** byte-verified constants (_DAT_0050e3d8/_DAT_0050e3d4, heat.cpp:63-80); an earlier 1e-4 misread made them fire 25-30x too eagerly (task #9 correction).
- **Port inventions still live [T3]:** frameEntryWorldVelocity restore; ramLastVictim/ramContactLinger 0.35s contact edge; the mid-clip bmp rebind guard; the collisionAssistant null guard. Port inventions REMOVED: ×1e-3 normalization, gBlockCooldown.
- **Known port drift touching the leak:** the heatLoad smoothing window is frame-rate dependent (28 Hz pod vs ~59 fps port halves the window → heatLoad 2x twitchier, heat.cpp:872-880) — documented as the #119 leak-voice stutter cause; also the port's impact |v| comes from the kinematic gait, not binary mover physics (the whole reason the contact-edge guards exist).
## C. Prior unresolved observations this audit should explain
1. **#103 (night-8, open era question):** ram → gyro/myomer damage + myomer coolant leak, no armor — filed as possibly-authentic, "awaiting a player ruling" on armor. #128 is the terrain-side escalation of the same mechanism; the night-8 disposition ("matches the divert, may be WAI") is the reason nobody treated the leak itself as a bug for ten days.
2. **The determinism testers report is SHAPED like the reconstruction:** ≥0.5 scaled pts (the "minimum speed" testers observe — ~18.5 u/s at 65t per 37dd7f9's message) → guaranteed ≥1 sub-hit → 0.3+0.35 cumulative weight on heat-family targets → any zone damage × running heatLoad ≥ 0.0025 → leak flag. Whether the 1995 pod also leaked on EVERY over-floor terrain crash is the open question — no ledger records a 1995-side check of leak frequency, only of the divert's structure.
3. **#135 (leak with NO flashing annunciators) and #97 (three-level leak severity, we only ever produce the lowest)** — both still open, both plausibly entangled with the leak-magnitude side of #128.
4. **The steam advancedDamage inconsistency:** before 4.11.885 the +0x268 gate varied per node in steam matches; testers could legitimately disagree about whether terrain rams did anything at all. Post-885 it is the host's egg mission-wide — if the host egg authors advancedDamage ON, every player rattles/leaks.
5. **Un-won roll fidelity:** the distributor deliberately does NOT normalize weights (mech.cpp:976-977 "faithful: the binary does not normalize") — with only heat-family+gyro+torso eligible, a sub-hit can land NOWHERE; nobody has verified the eligible-roster cumulative weight against the binary's actual roster order, which affects how often the rattle hits a heat-family (leaking) member vs fizzling.
==============================================================================
## Ticket #128 Task 3 — Field receipts from night-14 (build 4.11.857, 4 machines) and night-15 (build 4.11.883, 6 machines) steam logs
**Method note:** logs have no per-line timestamps; times were reconstructed from `[rstat] frames=N` anchors at 0.017 s/frame (validated against `[drive] dt=0.017`), linearly interpolated by line number (accuracy ~±1 s). Leak receipt = `[techstat] <sub> condition 2 SET` (condition 2 = CoolantLeaking per game/reconstructed/btl4galm.cpp:116) plus first-seen `[galm-item] cond=2` per subsystem. Scripts: scratchpad crash_analysis{,2,3}.py (session scratchpad dir).
### (1) Distribution
Night 14: **8,528** [crashdmg] events (dave 805, santo 1,065, michael 4,351, rajel 2,307). Night 15: **30,715** (Dave 856, rajel 6,468, acaci 9,378, Michael 9,680, santo 2,765, eleng 1,568). Amounts are wildly bimodal: **~98% of events are amount<2,000** (median ~250–530, p95 ~1.1–1.8k) at scrape speeds |v| 3–6.5; a thin tail of discrete rams: amount 10k–145k at |v| 16–60. n14 amt≥10k: 47 events (0.55%); n15: ~145 (0.47%). |v| shows hard structure: scraping saturates at |v|≈6.4–6.5; a dense cluster at |v|=34.3–34.9 (full-throttle wall rams, esp. rajel: 20+ rams all at 34.x); outliers 40–60 (falls/jump landings — inference). mass field is the mover's own mass (35k–90k, varies per mech pick), never the partner's.
### (2) Correlation + empirical threshold — THE KEY RESULT
The collision→instant-leak signature exists **only in advDamage=1 missions** and **only for discrete high-speed rams**, not scrapes:
- **Night 14, advDamage=1, amount≥10k: 7 events → 6/7 (86%) followed by an internal-subsystem `[techstat]` receipt within ≤1 s; 4/7 (57%) an explicit CoolantLeaking (cond 2) SET at +0.2–0.4 s.** Michael's 3 rams (14.8k/26.5k/30k raw, |v| 24.4–43.6): ALL THREE → `Myomers condition 2 SET` (coolant leak) at +0.2–0.4 s. Dave's: 76k ram → Gyroscope+HeatSink DMG at +0.0/+0.3 s; 33k ram → Myomers LEAK at +0.3 s. The struck subsystems (Myomers/HeatSink/Gyroscope/Condenser) are exactly the DistributeCollisionDamage lottery families — this is the rattle firing, receipt-latency "instant" [T2 from field receipts].
- **advDamage=0 (n14 40 events amt≥10k + n15 ~145): ~2/185 (~1%) show a ≤1 s receipt**, and those are ambiguous (one is ERSLaser_1, not a rattle-family sub — concurrent weapon fire). All other follow-ups sit at +1.3–9.9 s, i.e. ambient combat damage.
- **Empirical threshold:** no event below |v|≈15.5 ever priced ≥8k raw; the smallest ram that sprang a leak was raw=14,811 @ |v|=24.4 (65t). Scrape events (|v|≤6.5) never exceeded ~3.1k raw. So the field threshold ≈ **raw amount ~15k ⇔ |v| in the low-to-mid 20s** — matching Oracle's "needs some minimum speed" and consistent with the 0.5-pt free floor of the (2000/mass)/(27.78)² pricing (raw floor ≈ 0.19×mass = 9.6k–17k depending on tonnage/elasticity) [inference from mech.cpp:987-991 + data].
- 5-s burst-level correlation over ALL bursts (including scrapes) is only 5–22% (n14) and 0–6% (n15) — the tester "every single time" is about solid rams under advDamage=1, NOT scrapes. Baseline: leaks are common from ordinary weapon fire — 85–100% of cond-2 SETs have NO crashdmg in the prior 5 s (n14: 144/161 orphaned; n15: ~124/142).
### (3) Cadence — scraping is priced per frame
Yes, repeat-fire: consecutive-line [crashdmg] runs of 38–120 events at **25–82 events/s** (frame rate ≈59 → up to ~1.4 pricings per rendered frame). Confirms the santo observation: santo n14 worst run = 50 events in 1.1 s (45/s) totaling 35,601 raw; dave n14 = 50 in 0.6 s (82/s), 51,230 raw; rajel n15 = 94 in 2.2 s, 121,335 raw. Cluster-level (≤2 s gaps): worst = rajel n15, 1,829 events over 43.3 s totaling 1.77M raw. Each per-frame event is individually tiny (med ~300 raw ≈ 0.011 pt after scaling at 70t) → every one falls under the 0.5-pt free floor, so a scrape run costs ZERO through the rattle even when gated on — but the run's raw SUM (25k–121k) would rattle 1–4+ sub-hits if it were priced once as a single impact. The per-frame re-pricing therefore currently under-damages scrapes rather than over-damaging them (through this path).
### (4) advDamage=0 cross-check — THE GATE HOLDS
Night-15 receipts: advDamage=0 for effectively every mission with crash traffic (Dave 11×0/2×1 early, acaci's lone =1 receipt superseded by =0 600 lines later before any ram, Michael's =1 was pre-mission line 56; rajel/santo/eleng all 0). Under those adv=0 receipts, **the instant collision→leak signature is ABSENT** (0–1 borderline in ~145 rattle-eligible rams, 0.7%). The signature appears exactly and only where [exp] advDamage=1 (dave/michael night 14). **Field receipts therefore show the port's rattle path HONORING the +0x268 gate — the leak does NOT come from a gate bypass.** Corollary: the testers who reported "every single time" were almost certainly dave/michael in the n14 advDamage=1 missions (5 and 3 such receipts respectively), or in non-steam sessions outside this evidence set.
### (5) Wall vs mech-ram
Not distinguishable from these receipts: [crashdmg] carries no partner identity and mass= is always the logger's own mover mass. Indirect only: the |v|=34.x pile-up is top ground speed into static geometry; |v| 40–60 outliers imply falls/DFA. No receipt-visible difference in leak outcome by |v| class beyond the amount threshold.
==============================================================================
TICKET #128 — BINARY TRUTH: THE COMPLETE 1995 COLLISION-DAMAGE CHAIN
=== STAGE 1: THE EMITTER (who dispatches, with what amount) ===
Pricing is ENGINE code we compile against [T0], dispatch is BT binary code [T1].
1a. Per-contact pricing — Mover::StaticBounce (C:/git/bt411/engine/MUNGA/MOVER.cpp:1433-1528) [T0]:
- impact = worldLinearVelocity · surfaceNormal (the NORMAL component only; grazing scrapes contribute little).
- impact > 0 (moving away) -> return 0. No other speed gate on damage: minimumBounceSpeed (streamed Mover attr "MinimumBounceSpeed") only zeroes *elasticity for slow hits (MOVER.cpp:1470-1473) — it kills the rebound, NOT the damage.
- Return value (MOVER.cpp:1527): -0.0005·(vn·vp)·moverMass, which algebraically reduces to raw = 0.0005 · moverMass · (1−e²) · impact² — the kinetic-energy loss in kilojoules (mass in kg, velocity m/s; the DynamicBounce comment at MOVER.cpp:1569 confirms the kJ intent). This is the amount [crashdmg] prints.
- Mover::ProcessCollision (MOVER.cpp:1365-1414) calls StaticBounce per contact; Mover::ProcessCollisionList (MOVER.cpp:1214-1360) SUMS raw damage across the frame's contacts (total_damage, :1283/:1350), sets damageType = Damage::CollisionDamageType (= 0, :1228) and damageForce = post−pre velocity delta (:1351).
1b. Dispatch — the binary's ground+collide response block (port Mech::AuthenticGroundAndCollide, game/reconstructed/mech4.cpp:8383-8537; binary @4aa630-@4aab5f, recovered byte-by-byte from the export gap, raw disasm scratchpad/night6/gap_4a9770.txt) [T1]:
- crushable-icon contact (0.00123f sentinel) -> gyro crunch only (@4aa7ce-4aa871), NO TakeDamage.
- blocking contact with damageAmount > 0 -> full frame rejection (velocity zeroed, position restored) + @4aa984-4aaab4 builds TakeDamageMessage{id 0x64, zone=-1, the collision Damage VERBATIM} and Dispatches it at the mech ITSELF. There is NO minimum-amount/speed gate at the emitter: ANY nonzero closing contact dispatches. (iv2 > 40 (u/s)² @0x4ab184 gates only the knockdown/bump ANIMATION ≈ 22.8 km/h.)
=== STAGE 2: THE DISTRIBUTOR — FUN_0049ffcc @0049ffcc (part_012.c:14374-14430) [T1, decomp + raw disasm scratchpad/night6/gap_49ffcc.txt] ===
Reached ONLY via the hub Mech::TakeDamageMessageHandler @0x4a0230: part_012.c:14636-14638 — `if (damage.damageType == 0) { FUN_0049ffcc(mech, &damage); goto LAB_004a07b5; }` — the goto jumps past the zone/armor loop entirely. Collision damage NEVER touches zone armor, in either gate state.
2a. THE GATE (@0x49ffde): `if (*(victimMech+0x190 /*owning BTPlayer*/ +0x268) == 0) return;` — the SECOND advancedDamage cell (egg/technician "splash/collision damage" setting). Gate OFF = TRULY NOTHING: the entire function body is inside this if; combined with the hub's goto, a collision then costs zero armor, zero subsystems, zero anything. [T1]
2b. THE SCALING (@0x49ffff-0x4a0030): amount *= ((2000/moverMass) / ((100·(1/3.6))²)) / (1 − elasticity²). Constants from raw disasm: tbyte @0x4a0148 = 0.2777778 (1/3.6, km/h→m/s), 2000f @0x4a0154, 1.0f @0x4a0158, mass @mover+0x20c, elasticity @mover+0x244. Multiplied against the raw kJ from Stage 1, EVERYTHING CANCELS: scaled = 0.0005·m·(1−e²)·v_n² × 2000/(m·771.605·(1−e²)) = (v_n/27.778)² — the squared ratio of normal impact speed to 100 km/h, independent of mech mass and elasticity [T1 algebra on T0+T1 inputs].
2c. THE THRESHOLD (@0x4a003c-0x4a0045): scaled < 0.5f (@0x4a015c) -> return, FREE. => minimum damaging impact: v_n ≥ 27.778·√0.5 = 19.64 m/s ≈ 70.7 km/h closing normal speed, for EVERY mech. Walking scrapes (tangential, or slow) are free by construction.
2d. SUB-HIT COUNT (@0x4a0051): n = _ftol(scaled × 2.0f (@0x4a0160)) — FUN_004dcd94 is the CRT _ftol, not a helper (Ghidra shows ROUND(ST0); MSVC _ftol truncates — minor rounding uncertainty, n identical at all half-integer boundaries). amount /= n (@0x4a0065). With truncation each sub-hit is 0.5-1.0 points (n=1 for scaled∈[0.5,1), n=2 at 100 km/h, n=3 at ~140 km/h, n=6 at 182 km/h supercharge).
2e. TARGET SELECTION (the loop @0x4a006b-0x4a0121; NOT FUN_004ac07c): per sub-hit, roll = FUN_00408050() = rand()·(1/32768) ∈ [0,1) (part_000.c:7930); walk the subsystem roster (count mech+0x124, array mech+0x128) in ROSTER ORDER; an entry is ELIGIBLE iff FUN_0041a1a4(its derivation chain, TAG) matches one of THREE tags (part_012.c:14403-14410): 0x50e590, 0x50fdc0, 0x510b08; accumulate eligible entries' collisionCriticalHitWeight (+0x10C, streamed res+0xDC "CollisionCriticalHitWeight"); first entry whose cumulative ≥ roll receives the sub-hit via FUN_004ac07c and the walk breaks. Weights are UN-NORMALIZED: an un-won roll lands NOWHERE (faithful).
2f. ELIGIBILITY — the tags [T1, with a KB-internal contradiction I must flag]: FUN_0041a1a4 (part_002.c:3843) matches by Derivation-object POINTER IDENTITY walked up the parent chain. 0x50fdc0 = Gyroscope's node (DefaultData 0x50fdb0+0x10), 0x510b08 = Torso's node (DefaultData 0x510af8+0x10). 0x50e590 = the HeatSinkBank/AggregateHeatSink (0xBBE) node — NOT the HeatSink base family: decomp-reference.md rows 55+87 (task #57 correction) say so, and it is logically forced by part_013.c:5864 — the HeatSink base ctor itself tests 0x50e590 to let ONLY the bank skip the sink link-attach (heat.cpp:620-628 task #9, live-verified: treating it broader blocked condenser→bank conduction and caused the heat runaway). So the BINARY's eligible set = {HeatSinkBank, Gyroscope, Torso} — authored weights 0.30/0.35/0.25 (Σ=0.90; 10% of rolls land nowhere). The authored Myomer weight 0.35 is DEAD DATA for collisions (myomers are PoweredSubsystem-derived, no gyro/torso/bank tag in their chain; the other +0x10C-like path, zone crits @0049ccc4, uses the ZONE's crit-entry list weights instead). ⚠ CONTRADICTION: game/reconstructed/mech.cpp:1004-1018 (DistributeCollisionDamage) and context/combat-damage.md:1120 read 0x50e590 as the whole HeatSink FAMILY (BTHeatSinkFamily() returns HeatSink::GetClassDerivations(), heat.cpp:1447-1450) — that broadens eligibility to condenser/reservoir/generator/sensor/MYOMERS/weapons, i.e., nearly the entire coolant-bearing branch. This is a prime #128 root-cause candidate (see verdict below).
2g. THE APPLICATOR — FUN_004ac07c (part_013.c:4274-4282) [T1]: NOT a picker. It snapshots the target subsystem's PRIVATE zone damageLevel (this[0x38]+0x158, the Subsystem::damageZone @+0xE0), calls the subsystem's TakeDamage virtual (vtbl+0x24) with the (scaled, divided) Damage, returns the delta. The MechSubsystem vtbl+0x24 analog FUN_004ac0bc (part_013.c:4290): zone->TakeDamage (zone vtbl+0x18; DamageZone::TakeDamage @0041e4e0 == DAMAGE.cpp:391: damageLevel += amount × damageScale[type]) then if level ≥ 1.0 (_DAT_004ac140) -> failure states (Destroyed). The private zone's damageScale[0] (collision) is the authored damageTypePoints normalized as scale = 1/(points·defaultArmorPoints) (mechsub.cpp:221-237, ArmourNumerator=1.0 @0x4ac860) — exact authored bank values not pinned [T3].
=== STAGE 3: THE LEAK ONSET — HeatSink::UpdateCoolant FUN_004adbf8 (part_013.c:5733) [T1 decomp, constants T2] ===
Run per-frame from HeatSink::Update for every HeatSink-DERIVED subsystem only (CLASSMAP.md tree: HeatSink -> Condenser/Reservoir/HeatSinkBank/Generator/PoweredSubsystem -> Sensor/Myomers/MechWeapon...). Gyroscope and Torso are HeatWatcher->PowerWatcher-derived (CLASSMAP.md:34-98) — they have NO coolant members and CANNOT leak.
- coolantDraw(+0x130) = ownZoneDamage (this[0x38]+0x158) × heatLoad (+0x120, the SMOOTHED radiated-heat running average, attr "NormalizedPressure");
- draw < 0.0025 (_DAT_0050e3d8) -> zeroed (the floor);
- the draw drains own coolantLevel(+0x12C) × dt, replenished by DrawCoolant (vtbl+0x38, @0x4add00) recursing up linkedSinks × coolantFlowScale(+0x15C) to the Reservoir (@0x4af3b0) — the cockpit coolant bar visibly drops;
- HYSTERESIS coolantActive(+0x138): OFF->ON when draw > 0.003 (_DAT_0050e3d4); ON->OFF when draw < 0.0025. coolantActive IS the ReportLeak attribute ridden by the 19 authored leak watchers (the 3-note warning) and the "CoolantLeaking" TechStatusType (@50df17).
- LEAK CONDITION: zoneDamage × heatLoad > 0.003. One 0.5-1.0-pt rattle sub-hit gives zoneDamage = amount × damageScale[0]; with any working heat load (live port measurements saw myomer heatLoad ≈ 0.014 at idle-ish work: 0.5×0.014 = 0.007 > 0.003) a SINGLE sub-hit plausibly crosses the threshold immediately — the leak is instant once a coolant-bearing subsystem is rattled at all [formula T1; magnitude T3 pending authored bank points].
=== THE EXPLICIT ANSWERS ===
(a) When does 1995 dispatch damage at all? The self-TakeDamage(type 0) is dispatched on ANY blocking contact with nonzero closing normal speed (no emitter threshold). But it has EFFECT only when the distributor's scaled amount (v_n/27.778 m/s)² ≥ 0.5, i.e. closing NORMAL speed ≥ 19.64 m/s ≈ 70.7 km/h — mass- and elasticity-independent (exact cancellation). Below that every scrape/tap is free; gate (+0x268) OFF makes ALL collisions free. Mech envelope: stat-sheet speeds 40 (gimped)/143 (normal)/182 (supercharged) kph (context/pod-hardware.md:589-598) — so a run-speed head-on ram crosses easily, a walk or graze never does.
(b) When does 1995 first spring a coolant leak? Requires ALL of: (i) advancedDamage(+0x268) ON; (ii) v_n ≥ 70.7 km/h (≥1 sub-hit); (iii) the lottery landing on the HeatSinkBank — the ONLY coolant-bearing eligible class — probability 0.30 per sub-hit (gyro 0.35 and torso 0.25 rattles cannot leak); (iv) resulting bank zoneDamage × bank heatLoad > 0.003 (plausibly crossed by one sub-hit on any warm mech). Per-ram leak probability ≈ 1−0.7ⁿ: ~30% at 71 km/h (n=1), ~51% at 100 km/h (n=2), ~66% at 140 km/h (n=3), ~88% at 182 km/h (n=6). 1995 is NEVER "every single time".
VERDICT for #128 (inference from the above): the deterministic instant leak the testers report cannot be authentic 1995 behavior at any speed. The port's DistributeCollisionDamage (mech.cpp:1016) broadened 0x50e590 from bank-only to the whole HeatSink family — so myomers (weight 0.35 EACH, several per mech) and other coolant-bearing subsystems enter the lottery, the cumulative weight saturates, and nearly every rattle sub-hit lands on something that runs UpdateCoolant -> leak virtually every qualifying ram. Compounding: the steam eggs now stamp advancedDamage mission-wide (commit 3545056), turning the gate ON for matches where it was silently OFF before, and the run-14 note (mech4.cpp:8523-8525) already flags the forwarded [crashdmg] amount as suspect vs binary.

Bench: detent 5 -> death -> `[respawn] Condenser1 valve detent 5 -> 1` |
| generator switching survives | `@004b215c` sets `generatorOn=1` (landed, #55); `@004b0e6c` only RESOLVES the source link -- **the weapon->generator taps are never rewritten** | gens re-light = already correct; **taps persisting = AUTHENTIC** |

## Addendum 2026-08-05 (#45 report tail): the VehicleDead SENDER moved
The death-transition dispatch site (mech4) is retired: the decoded sender is the TakeDamage
handler's death tail (@0x4a07d4-0x4a0890), now BTMechPostVehicleDead (btplayer.cpp) with the
BT 0x38-byte extension {killed-by player, kill zone}. The #55 NULL-playerLink fallback + the
DEAD_NOTIFY forensics moved into it intact; the #81 single-dispatch rule is unchanged. The
flow diagram above predates this -- read BTPostKillScore rows as historical (retired 08-05).
