#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.

#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.)

#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).

#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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

#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).

#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.

#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.

#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

#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).

#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).

#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

#98: CORRECTION -- restore the byte-verified condenser lamp table; my previous mapping was a guess and was wrong
|
||
|

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

#95: REVERT the salvo-damage hack; deliver the cluster the way the binary does
Supersedes the mislanch change in |
||
|
|
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).

#87: mech armour PANELS now darken with damage -- the .DZM material system was loaded and unused
Players: "the actual enemy mech in external view is not showing darkened armor panels". We swapped destroyed LIMB meshes but never darkened a panel. The 1995 game darkens armour through the MATERIALS. MakeMechRenderables (FUN_004cef28) built, per (damage zone, material), a watcher FUN_004573e4(material, &zone->damageLevel, 0.1f) that snapshotted the materials |

#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.

seek-4 verification harness (BT_FORCE_SEEK) + the full supercharge/overheat
arc measured live BT_FORCE_SEEK=<idx> pins the seek gear in MyomersSimulation (env-gated bench; the eng-page toggle stays the authentic path) -- the supercharge loop was unreachable on a headless rig. Measured (Black Hawk, WALLTEST, full autodrive at gear 4): - cold: drive=1.42843 (exactly 0.9999/0.7), demand 87.85, actual run 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.

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.

#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.

#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.)

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.

#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.

#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.

#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.

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.

#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.

#82 FINAL LAYER: the peer body-channel trn-lock -- a circling limper skated because the peer's turn-arm had no walk-demand yield and the trn speed exit read a dead replicant mapper cell
The master limped clean (218x gimp-cycle records, zero trn) -- a _ReturnAddress trap on SetAnimationState(4) proved ALL peer trn arming came from the port's own mech4 turn-step block, not the type-3 reader. Two dead ends, one root: - mech4 peer arm: gated on !wantsWalk (standSpeed < bodyTargetSpeed), exits trn when walking demand appears -- the leg twin's authentic precedence (part_012.c:12013, the Standing speed test outranks the turn test). - mech2 body case 4: bspd reads bodyTargetSpeed on ReplicantInstance; the local mapper's speedDemand is a dead cell on a peer (reads 0 forever -> no exit). Verified 2-node timeline: arena circle replicant 218x state-24 / 0x state-4 (was 116x trn churn), grass circle 235-clean, knockdowns bounded, 0 deaths. Diagnostics kept: BT_TRNTRAP ra-trap, BT_ANIMIND_CAP, [gimpfeed], [replgimp] extension. KB: locomotion.md trn-lock entry + the dead-mapper-cell lesson.

#83: the COLLISION DIVERT -- type-0 damage prices as internal rattle, never armor
The crash self-damage reconstruction (
|

|
|
9c83a468db |
#82 ROOT FIX: reconstruct the crash SELF-DAMAGE -- wall-grinding now hurts,
the knockdown storm self-limits, peers keep the limp
The 'peers see a limping mech skating' report decomposed into a wall-grind
KNOCKDOWN STORM: a gimped mech held against a blocking solid re-crashes each
time its gg cycle rebuilds speed (the gg ceiling is authentically the clip's
natural speed -- bhk1 ~14.9 u/s, ceiling+divisor @0x544/0x548, loader formula
byte-matched -- so iv2 ~222 >> the 40.0 threshold @0x4ab184), and every
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.

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).

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).

#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).

#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.

#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.

#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).

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.

#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).

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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

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).

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.

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] Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

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]

myomer damage reaches the wheels, legs gimp at half structure, reverse refuses -- and an ODR trap unmasked (#75/#78)

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.
Diags: BT_SELF_DAMAGE_ZONE, BT_DRIVE_LOG, BT_GIMP_SPEED.

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.

noframe: drop the drag-by-surface -- it is a finishing step, not a mode
Author's correction to the shape of yesterday's option. The intended workflow is: place the displays where you want them WITH their frames, quit, then edit glass_layout.cfg to turn the frame off. So a ,noframe window should be pinned, not draggable -- removed the WM_NCHITTEST -> HTCAPTION handler that made the surface a drag handle. The arrangement being finished is the point: with no caption there is nothing to drag it by, which is exactly what you want on a wall of monitors. Delete the flag to get the frame (and the dragging) back. Unchanged and still needed: SaveLayout writes the flag back, because any later drag of a FRAMED window rewrites the whole file and would otherwise strip it. Re-verified live: - Heat MFD comes up with WS_CAPTION clear and answers WM_NCHITTEST on its surface with HTCLIENT (pinned) -- no window reports HTCAPTION any more. - Comm MFD (unflagged) keeps its caption. - A framed window's WM_EXITSIZEMOVE rewrote the file and BOTH ,noframe flags survived, with the new header explaining the arrange-first workflow. - surround / exploded / pod / dev boot and simulate clean. Docs updated to describe the two-stage workflow rather than surface dragging: the file's own header, environ.ini's BT_GLASS_LAYOUT block, context/ glass-cockpit.md and the ledger (which records the removed behaviour so the next reader does not re-add it).

glass_layout.cfg: ",noframe" per-line option strips a window's title bar
Append it to a window's line and that window becomes a bare WS_POPUP -- no
caption, no border, just the display and its buttons -- for a multi-monitor
wall where the chrome is only noise:
Heat MFD=1920,0,657,539,noframe
Options are comma-separated after the four numbers and unknown ones are
ignored, so an older build reading a newer file loses the option but never the
line (the bindings.txt grammar rule, applied here).
TWO THINGS THAT WOULD HAVE MADE IT A TRAP, both handled:
- A frameless window has NO TITLE BAR TO DRAG, which is the entire point of
the sticky layout. So a noframe window is dragged BY ITS SURFACE:
WM_NCHITTEST returns HTCAPTION anywhere that is not a button, HTCLIENT over
one. Buttons stay clickable, and because Windows drives the move the drag
still ends in WM_EXITSIZEMOVE -- so it still saves.
- SaveLayout rewrites the WHOLE file, so it writes the flag back. Without
that, the first finished-drag after adding the option would have silently
stripped it.
Ordering: the flag is read BEFORE frame sizing (a quiet LoadLayout pre-pass,
then the normal pass after ComputeLayout), because AdjustWindowRect -- and
therefore the ring placement -- depends on whether a window carries chrome.
The pre-pass is quiet so the restore still logs exactly once.
Verified live: two flagged windows came up with WS_CAPTION clear while the
other five kept it (read back with GetWindowLong(GWL_STYLE)); a click still
dispatched on the frameless radar (CLICK 'Secondary / Radar' addr=0x18); and a
WM_EXITSIZEMOVE save round-tripped both flags back into the rewritten file.
surround / exploded / layout=off / pod / dev all boot and simulate clean.

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.
Diags: BT_CRIT_LOG ([subarmor] + [critroll]), the existing BT_DMG_LOG.

environ.ini: document BT_GLASS_LAYOUT in the shipped default
The default environ.ini template (BTWriteDefaultEnvironIni) now carries a commented BT_GLASS_LAYOUT block in the cockpit section, next to BT_GLASS_PANELS: off/save/load explained in player-facing terms, noting glass_layout.cfg lives beside the file and delete-to-reset. Ships commented out like every other option, so a fresh install still applies nothing. Verified: Release builds clean; the new text is embedded in btl4.exe.
