Mech::DuckRequest -- the CROUCH button, and a dead-button census that lied
The 2026-07-20 audit listed 8 panel buttons dispatching a streamed message with
no reconstructed handler. Only ONE was still missing: generator on/off,
ToggleSeekVoltage, EjectAmmo, ToggleCooling and BalanceCoolant had all landed
between 07-20 and 07-25 while pod-hardware.md and open-questions.md still called
them dead. docs/INPUT_PATH_AUDIT.md had already flagged the census as "stale in
both directions" and was right -- swept both files, and recorded the rule: check
the code, not the census.
DuckRequest @0049fa00 (id 0x1a, RIO 0x13 -- the manual gives crouch a whole
section). The binary's entire body:
if (0 < *(int *)(param_2 + 0xc)) { *(undefined4 *)(param_1 + 0x398) = 1; }
Press-only; sets duckState (mech+0x398, attribute 0x37). A one-shot REQUEST
flag, not a posture toggle -- the handler never clears it and the only other
writer in the whole binary is the mech reset (part_012.c:9439, the same reset
that zeroes incomingLock, which is how that region was already mapped).
WHY THE FLAG HAS NO READER, AND WHY THAT IS CORRECT. duckState has ZERO readers
anywhere in the decomp, because it is published as an ATTRIBUTE and consumed
through DATABINDING: content/GAUGE/L4GAUGE.CFG runs a 3-frame bduck.pcc
oneOfSeveralPixInt bound to DuckState -- "crouch mode: button 4" on the map's
legend column. Verified live by capturing the Secondary/Radar window before and
after a 0x13 press: the crouch icon goes grey -> orange. So the handler is
COMPLETE. A crouch pose invented here would be a stand-in for data we have not
found (no SQUAT clip name survives in the decomp or in content/, only
DuckServo01.wav in AUDIO1.RES).
Bonus: those gauge widgets sit at offsets 537/430/322/215/108 -- a 107 pitch,
independently corroborating the map legend grid measured from pixels.
Still open from that census: MechRIOMapper's own Keypress @004d2514 (id 0x19).

MP match forensics: per-peer matchlog + relay auto-upload + matchcheck
For the 8-player playtest. Damage authority is VICTIM-side, so no single peer sees the whole match: every -net instance now writes a compact machine-parseable matchlog_<date>_<time>_<pid>.txt (auto-armed by -net; BT_MATCHLOG=1/0 overrides; solo silent), and at mission end a relay-mode pod dials the relay game port (the seat-request throwaway-dial pattern, envelope route -9) and streams the file back -- the relay saves every peer's copy under matchlogs/ on the operator's machine, so testers send nothing by hand. tools/matchcheck.py <dir> reconciles all of them: damage claimed (FIRE/PROJ/SPLASH/RAM, shooter-side) vs applied (DMG, victim-side authoritative), kill/death replication across observers, PLAYER_DEAD counts, scores, version skew, replicant-application and unattributed-damage anomalies, mid-mission disconnects. Hooks at the authoritative sites: Mech::TakeDamageMessageHandler (DMG, post-base, zone + post-application damageLevel), MechWeapon:: SendDamageMessage (FIRE), projectile impact/splash/collision dispatch (PROJ/SPLASH/RAM), wreck entry (DEATH -- a ONE-SHOT latch at MovementMode 9, NOT the transition: a replicant arrives at 9 straight from the type-6 record header and never runs the transition branch), BTPlayer vehicle/death/score handlers (VEHICLE/PLAYER_DEAD/SCORE), zone crit cascade (CRIT), APP.cpp RunningMission (MISSION), L4NET host handlers (PEER_UP/PEER_DOWN). Every line t=/w=/st=-stamped + fflushed. Verified 2-node: mesh run pairs A's 22 FIRE 1:1 with B's 22 DMG (same amounts, cylinder-resolved zones, ~200ms latency); force-damage kill run logs 103 DMG + 3 DEATH inst=M + 3 PLAYER_DEAD across three respawn cycles victim-side and the kill SCOREs shooter-side; relay-mode run auto-uploaded BOTH peers' files at the mission-clock stop and matchcheck produced the full report with exactly one (correct) anomaly -- the force hook's claim-less damage, the unattributed-damage detector working. Relay gained a route-specific 8MB cap for the upload frame (game frames stay capped at 1600). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

Issue #20: wire Mech BalanceCoolant (id 0x16) -- the auto-cooling-balance button
Third instance of the silent-swallow pattern (unregistered handler id ->
Receiver NullHandler). The Mech handler table @0x50BDF8 binds
{0x16, "BalanceCoolant" -> @0049f728}; the reconstruction never registered it.
Disasm-verified body (@0049f728): press-only guard (msg+0xc > 0; the binary
has NO novice lockout on this one), set EVERY condenser's valveState@0x1D0
to 1 (equal weights), then the shared redistribute @0049f788 -- which the
port ALREADY had faithfully as BTRecomputeCondenserValves (flow =
valve/total + condenserAlarm pulse; MoveValve calls it). So the fix is:
- mech.hpp/mech.cpp: BalanceCoolantMessageID=0x16 + handler + MESSAGE_ENTRY
- heatfamily_reslice.cpp: BTBalanceCondenserValves bridge (Condenser is a
complete type there; sets valves to 1 + redistributes)
- mech4.cpp: BT_BALTEST scripted harness (MoveValve press alternating with
a Balance press)
VERIFIED headless (BT_BALTEST=1 BT_VALVE_LOG=1):
boot -> all valves 1, flows 0.1667 each
MoveValve-> condenser#1 valve 5, flows 0.5 / 0.1x5 (the priority boost)
BALANCE -> all valves 1, flows 0.1667 each (equalized)
Awaiting the tester's live ADV-mode confirmation.
KB: decomp-reference.md Mech-table row marked wired.

Issue #3 (b)+(c): weapon damage reaches cultural icons -> full trkdead explosion + authored burn fire
(b) The 'tiny explosion' on the ram kill is AUTHORED: crunch res 31 = 'stephit'
(one video object, effect 1008 = ddam5 damage smoke) -- a step/ram squash is
small by design. The FULL explosion res 32 = 'trkdead' = psfx 15 dtrkboom
(fiery omni burst) + psfx 16 dtrkburn (the burning-wreck fire), reached by
WEAPON kills -- which the 1995 binary dispatches [T1]:
- MechWeapon::SendDamageMessage @004b9728 (part_013.c:6765) gates only
"target NOT derived from Mech@0x50bdb4 OR aimed zone set": a non-Mech
boresight target takes the zone=-1 damage UNCONDITIONALLY;
- Missile contact @004be078 dispatches at the struck solid's OWNER entity
with no class test at all.
Port wiring: Mech::WorldStructurePick returns the struck solid's owning entity
(BoxedSolid::GetOwningSimulation; TERRAIN.cpp:107/246 build every static solid
with its Terrain/CulturalIcon/Door entity as owner); the mech4 pick block
designates IT instead of the gBTTerrainEntity sentinel (sentinel = fallback);
the projectile contact path grew the non-mech damage-zoned else-branch
(@004be078 mirror, direct Dispatch). Plain terrain ignores the damage
(ENTITY.cpp:885 zone==-1 guard); an icon's handler maps -1 -> 0 and dies.
Truck armor is WeaponDamagePoints=1 (TRK.DMG): one laser = one dead truck.
(c) The burning fire is dtrkburn.pfx, authored INTO the death package (every
icon family carries 1016: trkdead/bigdead/meddead/msldead/twrdead). There is
NO looping BurningState fire in the binary: the damage-zone effect watcher
ctor @0042a984 has exactly one call site (the Mech ctor, part_012.c:10405), so
icon ExplosionTables are inert, and CulturalIcon has no Performance.
Documented as authentic -- nothing invented.
Verified live (BT_SHOT pixel capture): 26 laser kills, [cult] TakeDamage
type=3 -> DYING res=32 -> DPLIndependantEffect 1015+1016 at the icon origin;
frames show the orange dtrkboom fireball, dtrkburn flames on the fresh wreck,
and the rubble aftermath; ram harness re-run still fires crunch res 31.
Diags: BT_FIRE_AT_ICON (designate nearest ahead icon; live-icon census in
CULTURAL.cpp), BT_FX_TEST="1015,1016".

Camera seat LIVE + Mech::PlayerLinkMessageHandler reconstructed (@0049f624)
The spectator/broadcast seat works end-to-end: a hostType=1 +
vehicle=camera pilot page boots a CameraShip whose 62-camera arena1
network loads from the BTL4.RES type-27 resource (the engine's
CreateStreamedCameraInstances existed all along -- the file probe falls
back to it), the BTCameraDirector locks onto the first live mech, and
the ship TRACKS it (sees=1, goal advancing) and CUTS between authored
camera positions (screenshot-verified: wide arena shot -> close
tracking shot).
The missing piece was the Mech override of PlayerLinkMessageHandler
(@0049f624), which the reconstruction never filled. The engine base
resolves mech->player; BT's override adds:
1. the REVERSE link player->playerVehicle = this on EVERY node
(replicants included) -- how the camera director and scoreboard
find a REMOTE player's mech; without it a spectator parks forever
('NO goal entity')
2. clears NonScoringPlayerFlag (0x4000 = bit 14): a pilot with a
vehicle is a SCORING player -- this admits REPLICATED players to
the ranking pass, so cross-node rank/score displays work
3. master only: seeds the heat bank's ambientTemperature (bank
@0x1d4) from the mission [mission] temperature= (BTMission+0xf4)
-- correcting the heat family's 'frozen 300' deviation note (it
was never frozen; THIS is the writer)
Bridge BTSetBankAmbientTemperature lives in heatfamily_reslice.cpp
(mech.cpp cannot include subsystem headers -- local-stub collision).
BT_CAM_LOG diagnostics: camera-network count, director pick + Players
group census, ship follow state, link dispatch/receive.
Verified live: 2-seat (mech + camera) relay session -- replicated
player shows +veh, director goal locked w/ 30s timer, ship tracking a
moving mech through camera cuts; standard 2-node mech smoke PASS
(un-regressed). Lesson re-learned: a 'clean' build filtered on 'error
C' missed a linker file-lock failure -- one whole test cycle ran
against a stale exe (the /FORCE gotcha's cousin; grep -i error, not
error C).
Remaining (task open): ranking-window overlay draw (L4VIDRND stubs),
operator-app camera-seat row, shot polish.

Per-pilot mech paint: wire the color/badge/patch substitution end-to-end
- Mech::resourceNameA/B/C -> real CString members (the binary's 16-byte CStringRepresentation; deep-copy bind from the MakeMessage = FUN_00402a98, implicit member dtors) + paint-name accessors - SetupMaterialSubstitutionList reads the real egg names ([paint] log); TearDown clears the callback first (FUN_004d11e8) - dpl_SetMaterialNameCallback is real now (L4VIDEO registry); bgfload MaterialResolver::resolve() applies it to every material name -- the port analogue of the dpl board rewriting names at load - MP_BHMC.EGG: color=Red -> Crimson (vehicletable has no Red; binary Fail()ed) Verified live 2-node MP: crimson MadCat with hip hazard stripes + yellow VGL leg emblems; white Blackhawk + emblems; replicants painted on both nodes.

Rear-fire + look views (task #68): the pod's rear arsenal reconstructed
The user's tip ("some mechs actually do fire backward") checks out end to
end. Binary ground truth [T1]:
- weapon+0x334 (attr 0x1B "RearFiring"): the ctor tests the MOUNT SEGMENT's
page name for the marker 'b' (@0x511aa2, part_013.c:6913-6930) -- the back
gun ports sitelbgunport/siterbgunport. The old reading ("EXT in the
weapon model name") was a double misread (wrong string, wrong name).
- mech+0x410 (attr id 50 "RearFiring"; the old `stateFlags` label): the ctor
ORs every weapon's flag (part_012.c:10220) -- "carries a rear arsenal".
- The mapper's five-state LOOK machine (part_013.c:396-459): on a state
change it re-aims the eyepoint (mech+0x360 = EyepointRotation -- consumed
by DPLEyeRenderable, already live in the port) and re-arms each weapon's
viewFireEnable(+0x3E0): FORWARD view = the non-rear weapons, LOOK-BACK
(yaw pi + lookBackAngle pitch) = the REAR-mounted ones, side/down = none.
+0x3E0 is the same flag the emitter's Loaded->Firing gate reads (the old
`useConfiguredPip` label) -- pips and fire permission both follow the view.
Port: rearFiring derived from the mount segment name (BTWeaponMountIsRear);
mech rearFiring ORed in the roster pass (the old SubProxy::IsDerivedFrom
stub returned 0 -- that loop never ran; now bridged through
BTWeaponIsRearFiring, which also fixes the weaponRoster fill); the look
commit is LIVE (BTCommitLookState: eyepoint EulerAngles from the authored
per-mech look angles -- now real members, were Wword scratch parks -- +
per-weapon view enables); MissileLauncher/ProjectileWeapon FireWeapon gate
on viewFireEnable like the emitter; RearFiring attrs (mech + weapon) bind
real members. Keyboard: HOLD 'V' = the pod's rear-view button.
Live-verified on the default blackhawk: ERMLaser_2 -> siterbgunport rear=1,
ERMLaser_3 -> sitelbgunport rear=1, PPCs/SRMs/torso mounts forward -- the
blackhawk authors TWO REAR LASERS (owens also has back ports). [rearfire]
trace under BT_PROJ_LOG.

Gyro tail + audio (task #66): the INSTABILITY MODEL -- mech+0x3F0 reconstructed
Byte-decoded the un-exported master-perf block @0x4aad3d-0x4aaf14 (capstone;
the same gap that held the F5 footstep code) [T1]:
instab = (min(|AccelerationLastFrame| / maxUnstableAcceleration, 1)
x unstableAccelerationEffect)^2
instab += clamp((demand - legCycleSpeed)/demand, <=1) # "gun the engine"
x unstableGunTheEngineEffect # (demand clamped to
# [gimpStride(neg), runMax2])
if (legAnimationState == 4 /*turn-in-place*/) instab += unstableStopedTurnEffect
clamp to 1 -> mech+0x3F0 -> gyro->swayBias (gyro+0x3A8)
Every piece resolves to already-reconstructed structure: the model-record
tuning block rec+0x80..0x94 (ctor copy @0x4a2593 -- the six authored
Unstable* fields, previously parked in the Wword scratch bank, now real
members); AccelerationLastFrame@0x82c = the snapshot of the ring-derived
localAcceleration (copied at the perf tail @0x4ab142); CurrentSpeed@0x348 =
legCycleSpeed; the trn state 4 gate; and the gyro feed lands in the
EXISTING swayBias member + GyroscopeSimulation consumer (task #56) --
GyroFrameJointWrite's "0.0f model TBD" argument is now the live value.
UnstablePercentage (binary id 52 @0x3F0) binds the real member: the LAST
dead audio attribute is live -- the authored instability alarm (start
thresh 0.01 + volume = the fraction) sounds under hard maneuvers, and the
cockpit ambient sway now scales with reckless driving.
Live verification (30s, 0.6-throttle run): instab 0.38 during the walk->run
chase (cyc 22.2 vs demand 33.6), settling to 0.002-0.12 per-stride ripple at
steady run; attribute binds with live float values; [instab] trace under
BT_GYRO_TRACE. unstableSuperStopEffect/unstableHighVelocityEffect writers
remain unlocated (plausibly the airborne perf variant) -- noted on members.

Audio: footsteps arrive on the FIRST stride -- the 10-20 s warm-up bug
User report: footfalls silent for the first 10-20 s of every mission (all
mechs), then solid. Root cause was three interlocking layers, each measured
with timestamped traces:
1. The authored footstep volume chain (LocalAcceleration [0,10]->ctl100 +
LocalVelocity [0,0.6]->ctl101 through authored N=30/N=15
AudioControlSmoothers, fill 0) hangs off the SOURCE's watcher chain
(scale watches smoother watches mixer watches source), and an idle
source's chain executes only at Start attempts -- one smoother sample
per stride.
2. Each hop is frame-gated (AudioComponent::ExecuteWatchers,
DefaultAudioFrameDelay), so any burst collapses to one execution.
3. The transient drop gate (vol < 0.3, AUDREND) rejected every Start while
the smoother average crawled up 1/30th per attempt -> ~25 dropped strides
before the first audible step, then per-frame execution while playing
kept it warm forever ("solid after that").
Fixes (engine-level, each documented in place):
- AudioScaleOf<T>::Execute now sends EVERY poll (scales are continuous
value-feeders; the base bitwise change-gate -- Motion::operator== is
memcmp -- froze on our deterministic gait math, where the original's
noisy physics floats never bit-repeated. Triggers/matchers keep the
change gate: their semantics are edge-based).
- Component/AudioComponent::PrimeWatchers(passes): recursive, GATE-FREE
watcher pump; AUDREND runs 30 passes on every transient Start request so
the authored smoothers evaluate at their true steady state before the
drop gate reads the volume.
- localAcceleration derives via the binary's exact structure: 15-sample
ring buffers of the raw position derivative + dt (ctor part_012.c:9836,
derive :15169-15195), in the PerformAndWatch tail so it runs every frame.
- AttributeWatcherOf::GrabCurrentValue private -> protected (the scale
override calls it).
Verified (30 s walk from cold start): drops 25 -> 3 (the survivors are
authentic quiet-stride gating: first gentle strides at vol ~0.28 vs the 0.3
gate), footfalls deliver from the first stride, 43 delivered with live
per-stride gain variation. Diag traces added: [accwatch]/[fsscale]/
[smooth]/[smoothcfg]/[motionscalecfg] + timestamps on DROP/volset.

Audio Phase 4d (AUDIO_FIDELITY F5): footStep is the authored CONTACT LEVEL
The binary's per-frame perf (disasm @0x4a9e80-0x4a9eb6 leg / @0x4aba86- 0x4abab9 body) computes footStep@0x394 = (jointlocal.y <= *footStepThreshold) with the threshold pointer = SequenceController+0x20 = &ANI hdr[2] -- the header word the engine's own AnimationInstance captures (JMOVER.cpp:1415) and our SelectSequence skipped. States 0/1 retain the value. Port: SelectSequence captures hdr[2]; PerformAndWatch evaluates the contact level per frame from the cached jointlocal root joint (leg channel drives the pose); the 150 ms clip-transition pulse + decay are RETIRED (steps fired at clip boundaries with a fixed width; clips whose root crosses twice or never counted wrong). Live verification (30s walk): the authored threshold decodes real (-0.232 root height); rootY oscillates across it per stride (-0.26 contact / -0.19 swing) with clean 0->1->0 transitions per leg state (5/6/7); 34 footfall deliveries at stride rate with per-stride varying gains. Also closes F23(2): the 17 authored AnimationState trigger states fire empirically -- the EngineShiftFwd/Rev heard during the gait dead-band hunt WERE states 10/11/14/15; the runtime clip numbering is correct.

Audio Phase 4c (AUDIO_FIDELITY F17/F19): impact scaling + the authored footstep feed
F17 CollisionSpeed (binary id 24 @0x4B4): real member captured as |worldLinearVelocity| when the contact accumulator arms (0->1) -- the authored AttackVolume [0.9,1] / Brightness [0.7,1] scales over impact speed [0,25] now make harder hits sound louder and brighter. ReduceButton (id 46 @0x340): real watchable member (the keyboard rig never presses it). UnstablePercentage stays deferred: its sway/overspeed model @0x3F0 is the known gyro-ledger gap (live writer unexported); binding without the model would be a stand-in. F19 footstep feed (the invention is dead, long live the authored chain): new [motionscalecfg/motiontrigcfg] traces recovered the authored configs -- EVERY motion watcher extracts |linearMotion| (motionValue=3); the footstep volume mixer is fed by LocalAcceleration [0,10] -> ctl100 (per-stride kick) + LocalVelocity [0,0.6] -> ctl101 (0.4 base while moving). The port never wrote Mover::localAcceleration, so ctl100 read 0 and the old mech2.cpp step-intensity broadcast (patch-sniffing, invented curve) fought the live authored scale. Now: localAcceleration.linear = d(published velocity)/dt -- EXACTLY the binary's derivation ((avgVel - prev)/avgDt into +0x1e4, part_012.c:15186-15195) -- and the broadcast is REMOVED. Regression (30s, walk throttle): stable; footfalls deliver through the wholly-authored chain with per-stride VARYING gains (0.61/0.72/0.62 -- real step dynamics, impossible under the old constant-curve invention).

Audio Phase 4a (AUDIO_FIDELITY F6/F7): coolant-leak warning + missile alarm
F6 ReportLeak (the largest dead authored block -- 38 of 54 match watchers):
recovered the binary HeatSink attribute table (16-byte {id,name,off+1} rows
@0x50e438..0x50e4c8, ids 3..12) [T1] -- it confirms EVERY existing heat
binding (CurrentTemperature@0x114 .. CoolantMassLeakRate@0x130, HeatSink@
0x164) and adds the one row we never published: ReportLeak (id 12) ->
+0x138 = coolantActive, the INT leak hysteresis flag UpdateCoolant
(@004adbf8) drives 1/0 around draw 0.003/0.0025. PoweredSubsystem derives
from HeatSink, so the single row serves all 19 authored leak watchers
through the chained index, exactly like the binary. MechWeapon's pinned-id
pad absorbed the +1 chain shift (0x0E -> 0x0F, tripwire fired as designed).
F7 IncomingLock/DistanceToMissile (missile alarm): binary Mech table walked
in full (ids 21..56 [T1] -- also settles FootStep@0x394, CollisionSpeed@
0x4B4, UnstablePercentage@0x3F0, ReduceButton@0x340 for the next findings).
IncomingLock id 54 @0x3fc, DistanceToMissile id 56 @0x400; the old
"maxSpeed @0x400 = FLT_MAX" member was a MISREAD of the far default and is
retired (its 1000.0f "override" was RadarRange id 47 @0x404, already
published). Real members + accumulators: Missile::MoveAndCollide reports
target + range each tick (BTReportIncomingMissile bridge); PerformAndWatch
latches per frame. The authored beeper (match 1/0) + range->TEMPO scale
(100..800 -> 600..10, accelerating as the missile closes) read them
unchanged. Drive is intent-level [T3]; init 0/FLT_MAX matches the binary
reset (part_012.c:9446-9447).
Regression (30s): stable; ReportLeak binds real on every subsystem (0 pad
redirects); DistanceToMissile binds with FLT_MAX live; attrnull 41 -> 3.

Audio: kill the per-footfall static -- smooth the PUBLISHED velocity (task #50)
User pinpointed it: the per-stride 'static' was NOT the footstep sample -- it was the ambient engine hum being interrupted in time with the footfalls. Diagnosis (live tape): EnginePower01 was caught in a rapid Play->Stop cycle (80x/session). The idle-hum is gated by authored LocalVelocity triggers (hum ON in speed [1,20], OFF above 20) -- and the port's localVelocity is a RAW per-frame position derivative that pulses with every stride (gait acceleration + ground-snap bob). At walking speed |v| straddles the 20 band edge, so the trigger Start/Stop-flapped the hum on every foot plant; at run |v| >> 20 keeps it off (matching 'goes away at higher speeds'). Fix: ~0.25s exponential filter on the PUBLISHED localVelocity.linearMotion (fwd + vertical) -- kills the stride ripple, tracks real speed changes within a couple strides. The physics worldLinearVelocity (StaticBounce, collision damage pricing) is untouched; update records + the impact gate get the smoother value (both benefit). VERIFIED: EnginePower 1 play / 0 stops for the whole run (was 80 stop-cycles); FootFall cycles normally per stride; gear shifts/windup lifecycle intact.

Audio: footstep pulse VERIFIED end-to-end to the matcher; volume chain traced (task #50)
Footstep chain progress (each step empirically verified): - The FootStep watcher is an AudioMatchOf<Logical> (AudioLogicalTrigger extends AudioMatchOf, NOT AudioTriggerOf): authored config match=1 -> Start(2.0) on a DirectPatchSource. [trigcfg]/[matchcfg] ctor dumps added. - The pulse was pinned at 1: the decay lived in IntegrateMotion, which the current gait path NEVER CALLS. Moved to Mech::PerformAndWatch (provably per-frame) with a time-based 150ms window sized to the ~10Hz watcher poll. The matcher now fires per stride (14/run, was 1). - Every footstep Start is DROPPED at the renderer: the source's volumeScale is 0 (five VolumeAudioHandler sends of exactly 0 = inert/one-shot primes). The volume arrives through the authored control chain (AudioControlMultiplier inputs ctl 100+; one 0 input pins the product). Chain scales identified on this entity: LocalVelocity (live), LocalAcceleration (live), Myomers. SpeedEffect (=1.0 healthy; one authored scale maps [0,1]->[1,0] INVERTED), UnstablePercentage (INERT PAD -- always 0!), HeatSink.CurrentTemperature. PRIME SUSPECT: an UnstablePercentage-fed multiplier input primes 0 once and never updates (the pad never changes), pinning footstep volume at 0. - SF2 numbering fact recorded: 38 presets in AUDIO1 / 5 in AUDIO2 have wPreset != file index (gap at preset 77); my table keys by wPreset. The 184x ProgramButton01 (bank1 patch83) storm at ~7/s needs an identity check against index-numbering (it may be the wrong sample for that patch id). Diagnostics added (BT_AUDIO_SPATIAL/BT_ATTRBIND_LOG): [trigcfg]/[matchcfg] ctor dumps, [matchfire] with component ptr+class, [volset] VolumeAudioHandler, [mult0] multiplier zero-products, scale sends with authored boundaries, [fswatch] dedicated footstep watcher tracer (g_btFootStepAddr), SetupPatch ENTRY with bank/patch/state, Simulation::DebugAudioWatcherCount. NEXT: back UnstablePercentage with a real (live) member -- it is the mech's stability 0..1 (the stabilityAlarm/gyro family) -- or confirm via a one-run chain dump which multiplier input pins the FS source; then the footstep transient should clear the 0.3 drop gate at walking speed.

Audio: restore the dropped ExecuteWatchers poll -- polled audio watchers were ALL dead (task #50)
User: "when I start moving all the sounds fade away, no footsteps." Diagnosis chain (all empirical, BT_AUDIO_SPATIAL/BT_ATTRBIND_LOG traces): - The audio head DOES track the mech (listener-relative positioning verified while driving) -- not a spatial bug. - The idle sounds correctly STOP on leaving the standing state; the MOVING sounds never started because every POLLED audio watcher was dead: the reconstructed Mech::PerformAndWatch replaced the engine performance but dropped the ExecuteWatchers() step from the engine tail (Simulation:: PerformAndWatch = Perform -> ExecuteWatchers -> WriteSimulationUpdate). Only PUSHED StateIndicator watchers (SetState->Execute) ever fired -- which is exactly why state sounds worked but footsteps/motion-scaled audio didn't. FIX: poll ExecuteWatchers() (AreWatchersDelayed-gated) before the update write. Immediately unlocks the polled family: MissileLoaded01/LaserLoaded01 ready dings, ProgramButton01, motion scales (PlayNote 15 -> 30 per run). - FootStep (0x1e) backed REAL: was the inert attrPad (an AudioLogicalTrigger polls it -- threshold-crossing pulse per foot plant). New footStep member, pulsed by SetBodyAnimation on entering any locomotion clip 1..0x17 (runtime stride alternation MEASURED as body states 12<->13 -- the enum-name numbering does not match runtime clip ids), decayed by IntegrateMotion (~1/3 s). - Footstep volume is speed-scaled (AudioMotionScale on LocalVelocity): at standstill the transient start computes volume 0 and the renderer drops it (LowAudioVolumeThreshold) -- so footfalls are audible at real walking speed. Diagnostics kept (BT_AUDIO_SPATIAL): spatial dist/vol per source, CLIPPED/DROP/ START at the request gate, vol=0 factor breakdown, scale->0 sends, trigger notifications, watcher poll-rate probe.

Audio: in-game TRIGGERING works -- real StateIndicator attrs + audio-watcher databinding (task #50)
Enabling audio unlocked L4AudioRenderer::CreateEntityAudioObjects, which binds AudioStateWatchers to entity/subsystem state attrs BY NAME (attribute-pointer databinding) and calls AddAudioWatcher on them. The reconstruction pointed the Mech's state attrs at the scalar read-pad `attrPad` (fine for gauges that READ a value, fatal for a state watcher that calls a METHOD) -> AV in SChainOf::Add on 0xCDCDCDCD. Root-caused via cdb + a BT_ATTRBIND_LOG trace in AttributeWatcher. Mech-level state audio now REAL + driven (verified: walking fires SetupPatch + PlayNote/alSourcePlay, patches 78/80/116): - AnimationState (0x1f) / ReplicantAnimationState (0x20): real StateIndicators (0x21 states covering MechAnimationState 0..0x20), driven from SetBodyAnimation so footstep/gait/transition sounds fire on animation change. - CollisionState (0x16): real 4-state StateIndicator driven from ProcessCollision via collisionTemporaryState (the deferred @4aa741 per-frame zero + the part_012.c:15406-15413 contact tail, InitialHit accumulation; the 1-vs-2 Slide split awaits the 0x240/0x244 floats still stubbed by fieldAt()). - @0x44c CORRECTED: "ammoState (0/1 leaking/2 dry)" was a mislabel -> it is collisionTemporaryState (never read as ammo). Bring-up guards [T3, temporary, self-clearing] so audio-on is STABLE while the subsystem state models are still stubs (Generators/Condensers/Myomers/Torso/ Avionics/Reservoir/ControlsMapper -- ~15 subsystems, ~40 attrs: GeneratorState, CondenserState, ReportLeak, ...): a NULL subsystem attr redirects to an inert pad (was a fatal Fail); an AudioStateWatcher on an unconstructed StateIndicator (null/ 0xCDCDCDCD) skips instead of AV. Both pass automatically once the subsystem is reconstructed. Those subsystem sounds stay silent until then (their audio wave). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

MP: world structures (garages/walls) TARGETABLE -- boresight ray-tests the static collision tree (task #50)
The boresight's non-mech pick only sampled the VISUAL heightfield (BTGroundRayHit), which on arena1 is a single flat 'sky'-named ground mesh (and class-42 BuildTables likewise holds only 'sky') -- so shots passed THROUGH the garages/walls and only mechs moved the HUD range axis (user-reported regression: "buildings used to move the range axis; now only mechs do, and you can only fire at a peer"). Real fix: the boresight now ALSO ray-tests the ZONE'S STATIC COLLISION SOLID TREE -- the same geometry that already blocks the mech's walk. Authentic engine mechanism: Mover::FindBoxedSolidHitBy already tests the static world via zone->GetCollisionRoot()->FindBoundingBoxHitBy(line). Factored its "static world" tail into Mover::FindStaticSolidHitBy(Line*) (static solids only, no movers), wrapped by Mech::WorldStructurePick(start,dir,range,&hit) (builds the world-space Line, reads the entry point back via line->FindEnd since HitByBounded clips line->length=enter). Boresight pick order is now: closest MECH (PickRayHit, damage zones + lock) -> closest STRUCTURE (WorldStructurePick; occludes a mech BEHIND it; designates the gBTTerrainEntity sentinel + entry point, so the range caret reads the structure distance and NO lock ring draws, mech4.cpp:4529) -> flat ground (BTGroundRayHit) -> sky (fire-at-nothing). Also un-skips arena1's misnamed-'sky' flat ground so the ground tier works (btvisgnd geometry-aware skip + [mapent]/[rendent] census). Verified headless: a BT_WSWEEP horizontal ray-fan on arena1 tracks position (3/24 hits near the boundary -> 17-21/24 inside the interior garage cluster -> 3/24 past it = DISCRETE interior solids, not an enclosing box), no crash/assert/AV. Interactive aim (BTGetAimRay) can't run headless (no window -> noRay), so the sweep is the headless proof; interactive aim is user-verified. Note: FindBoundingBoxUnder (the ground/containedByNode BoundingBoxTree) is DOWNWARD-only (gravity/ground-snap: *height = FindDistanceBelowBounded), useless for a horizontal boresight; the static SOLID tree's FindBoundingBoxHitBy is the only ray-vs-world query.

MP: peer shakiness ROOT-CAUSED as single-box packet jitter (rig, not game) + affinity launcher (task #50)
The residual RANDOM peer shakiness on accel/decel was proven (BT_RXJIT record inter-arrival probe) to be TEST-RIG packet jitter, not the game: two Debug btl4 nodes on one box contend for CPU, so Windows batches their TCP delivery -- records arrive in bursts (max 56-226ms gaps, burstiness 3-7x) instead of even ~17ms. The peer dead-reckons across the gaps then snaps -> random shake. Pinning the nodes to disjoint cores restored even ~17ms delivery (burstiness ~1.0) and the shakiness vanished (user-confirmed 'that was it'). Real pods = dedicated machines, no contention -> never see it. So NO un-authentic jitter buffer -- the coupled body-channel peer (96a896a/f094d78/23f1532) is the authentic + correct finish. - mech.cpp: BT_RXJIT record-arrival-jitter probe (env-gated). - tools/mp_launch.sh: 2-node launcher that pins nodes to disjoint cores (bakes in the fair-delivery condition; documents why). - context/multiplayer.md: the finding, so it is not re-litigated.

MP: COUPLED peer motion -- authentic gait-driven position + master gait send-mirror (task #50, env-gated)
Finishes the coupled IntegrateMotion path the decomp workflow (wh1h5gnmc, 3 make-or-break claims CONFIRMED by adversarial verify) proved authentic: - Peer LINEAR position is SINGLE-SOURCE gait: IntegrateMotion integrates the body-channel cycleDistance into projectedOrigin.linear@0x260, copied verbatim to localOrigin -- NOT velocity dead-reckon (that is angular/heading ONLY). 0x260 'motionDelta' and 'projectedOrigin' are literally the same field; the 'contradiction' was our reconstruction's two misnamed shadows. - Master and peer run the SAME predictor; the master's SEND-mirror must run it too (binary FUN_004a9b5c @0x4aab9c) so a gait-driven peer stays anchored. Our mirror used the constant-velocity deadReckoner + overwrote bodyTargetSpeed live every frame -> could not model a gait peer (the tug-of-war). - T4 CONFIRMED: both channels pose the full skeleton (same JointedMover); keep the peer LEG channel (our body channel is unbound on the peer). CHANGES (all behind BT_MASTER_GAITMIRROR / BT_ROOT_POS, DEFAULT OFF -- zero change to shipped behavior until visually confirmed): - mech4.cpp: send-mirror advances projectedOrigin by the mj=0 body channel travel (mirrorBodyAdv) rotated by heading + last-sent angular vel, re-seeded to localOrigin on each send, instead of the deadReckoner; and stops the per-frame live bodyTargetSpeed overwrite so the mirror slews toward last-sent. - mech.hpp/mech.cpp: mirrorBodyAdv member. Measured A/B (autonomous through-zero sweep circle, the speed-change regime): velocity two-source (current default): ratio 1.0022 BUT user-visible glitch coupled, NO mirror (dense): ratio 1.86 (tug-of-war) coupled + gait mirror, dense OFF: ratio 1.14, back-steps 0.1% coupled + gait mirror, dense ON: ratio 1.043, back-steps 0.1%, maxStep 2.9u The single-source coupling is proven (backward-stepping 0.1% vs the split's churn). Residual 2.9u occasional snap = leg(peer)-vs-body(mirror) channel mismatch, second-order. Awaiting visual confirmation before default promotion.

Diag: speed-change investigation -- authentic analog throttle CONFIRMED, harnesses + gait probes (task #50)
Decomp workflow w0odszxro settled the speed model: the pod throttle was ANALOG- CONTINUOUS (RIO Ranger, 800 ADC counts, 0.05 deadband; sole detent = snap-to-1.0 within 0.05 @004d196c). '5 speeds' is FALSE -- the 1-5 keys are MFD mode pages; the 0..5 stepper is HUD/radar zoom. BONUS: throttleState@0x4a4 is a MISNOMER -- binary census proves it is the fall-contact surface material cache (0..7, init 2=Concrete), written only at knockdown; rename pending. Empirical rule-outs (autonomous drive-sweep harness, this commit): - Record density: with the clock guard + incremental heading in, a per-frame continuous demand sweep measures IDENTICAL to constant throttle on position evenness ([repljit]), render heading ([rendhdg]), and gait cadence ([gaitev]). - Type-3 stomps: ~0 fire in sustained sweeps (only at launch) -- not the driver. - The 0.05-grid keyboard publish experiment is retained env-gated OFF (BT_GRID_LEVER) -- the ADC was ~continuous, so the grid is NOT authentic and gains nothing measurable; default publish stays continuous (authentic). New tooling: BT_DRIVE_SWEEP[0] (forced-drive triangle sweep, optional through- zero), BT_FORCE_STEP (0.05-grid variant), BT_GAITEV (per-frame leg-clip advance + state-flip + demand-change stats), [t3rx] (type-3 stomp trace). STATUS: user still reports visible speed-change glitches in interactive play; all harness metrics saturate at baseline -- next step is probes ON the user's interactive session (their eyes + instruments on the same run).

MP: FIX keyboard-driving peer skip -- non-pose records no longer kick the dead-reckon clock (task #50)
The discriminating user report: peer motion was smooth under the autonomous harness but skipped when driven by KEYBOARD -- even pure walking / pure spinning. The harness pins throttle/turn constant; the keyboard SWEEPS the throttle lever every frame of a key-hold (mech4 sLever integrator), so mapper->speedDemand changes every frame, and the speed-deadband gate (authentic exact !=) fires a type-2 speed record EVERY FRAME for the whole accel/decel. The base reader Simulation::ReadUpdateRecord stamps lastUpdate=Now() on EVERY record (flagged 'HACK - should be based upon message->timeStamp' in the 1995 source) -- so each type-2 SHRINKS the peer reckoner's projection span (nextUpdate-lastUpdate) without refreshing updateOrigin: the position target jumps backward toward the stale origin, the next pose record yanks it forward -> target oscillation every frame during any input sweep. Matches the session-long 'worst on accel/decel'. FIX (mech.cpp Mech::ReadUpdateRecord): non-pose records (2,3,5,6,7,8) preserve lastUpdate around the base call (keeping the real payload, simulationState). Pose (0) and resync (4) keep their authentic clock behavior. BT_T2_CLOCK restores the old stamping for A/B. REPRO HARNESS (mechmppr.cpp): BT_FORCE_SWEEP=<period> triangle-sweeps the forced throttle 0.2..0.9 -- a type-2 record per frame, the keyboard-skip repro the constant-throttle harness could never produce. Verified A/B, autonomous circle+sweep (the keyboard regime): old clock: worst frame spike 10.4x avg, path/net ratio 1.069 (backtracking) guarded: worst 4.6x, ratio 1.0022 (no backtracking) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

MP: FIX walk+turn peer skip -- incremental heading integration + scalar yaw mirror (task #50)
The user-keyboard regime (steering WHILE walking) fired BOTH dense record streams at once and exposed the last divergence: our peer heading used the engine Mover::DeadReckon slerp-toward-projection, whose angular projection reads the SHARED lastUpdate/nextUpdate timebase. The dense type-0 pose stream resets that timebase every frame while walking while RESTORING a stale orientation (the authentic case-0 strip, verified against FUN_004a1232 case 0) -- so the angular target barely advances from a stale base and the slerp DRAGS the heading back every frame. Measured: peer yaw advancing at ~40% rate with half the frames stepping BACKWARD. Pure-spin and pure-walk tests never showed it (single stream) -- why autonomous looked smooth while keyboard play skipped. AUTHENTIC FIX (decomp FUN_004ab1c8 -> FUN_004ab188/FUN_00409f58): the original replicant integrates its heading INCREMENTALLY from the CURRENT pose -- exact rotation of (replicated yaw rate * dt) composed on each frame -- and re-anchors on type-4 receipt. It never slerps toward a projected angular target. - mech4.cpp peer branch: save heading, let DeadReckon own LINEAR only, then integrate heading incrementally (ReconQuatIntegrate); on angSyncLatch (new type-4) re-anchor to updateOrigin. - mech.hpp/mech.cpp: angSyncLatch member (angular analog of poseSyncLatch), armed by ReadUpdateRecord case 4. - SCALAR peer-yaw mirror (angMirrorYaw/Rate/Time, re-based in the type-4 writer): replaces the quaternion projectedOrigin mirror for the ANGLE deadband -- the old one was recomputed each frame by the master's own reckoner from timing it does not control and false-fired in pi-waves (measured maxAng~=pi bursts -> periodic resync floods). - Dense-rot type-4 send REMOVED (was masking the old crude projection; not authentic; churned the shared horizon). Orientation now rides the sparse angle/velocity deadband resyncs exactly as the binary's. Verified live-autonomous: - pure spin: 59/59 perfectly regular peer yaw steps; master resyncs 0/s with mirror drift ~5e-7 (records near-silent, authentic sparse model). - walk+turn circle (the user regime): peer sim yaw monotonic at exactly the master's rate (0.00556/frame @ 0.327 rad/s), no backward steps, no stalls.

MP: FIX phantom walk-in-place -- master sends a pose record on came-to-rest (task #50)
The linear pose send-gate watched only POSITION drift + the 2s heartbeat. When a mech stops, its localOrigin is pinned and the master's own dead-reckon projection re-bases to it each frame, so error->0 and NO pose record fires -- leaving the peer holding the last WALKING velocity (updateVelocity). The replicant then dead-reckons + animates a phantom walk-in-place until the 2s heartbeat (stretched to ~30s when the master window is OS-throttled to ~8fps while backgrounded during solo two-window testing). Add the symmetric linear 'came-to-rest' trigger -- the exact analog of the angular (live yaw-rate==0 && replicated yaw-rate!=0) resync trigger already present in the type-4 gate: fire a pose record the frame the live horizontal speed collapses while the last-SENT speed was still non-zero, so the replicant receives velocity=0 immediately instead of waiting for the heartbeat. Diagnosis established via BT_WIRE tx0/rx0 probes: records deliver 1:1 (239 tx =~ 240 rx), velocities match -- NOT a replication stall; the master simply never transmitted the stop. Also confirmed the dominant choppiness is OS window-throttling (master 8fps backgrounded vs observer 63fps), a two-windows-on-one-box test artifact absent on real pod hardware.

MP: replicant motion chop ROOT-CAUSED + FIXED -- stale peer-mirror spammed re-base
records; also the 2007 call-counter clock stub + two crash fixes
User-reported: peer mechs turn/move choppy ("missing frames"). Measured per-frame
(BT_REPL_HDG): 13% of frames the replicant's heading STALLED, 11% it JUMPED 2-6x.
THREE layered defects found:
1) THE CLOCK STUB (engine substrate): TIMESTUB.cpp's GetRTC/GetHiRes were 2007
`return time++` call-counters -- the "clock" advanced per CALL, not per ms --
and TIMESTUB won the /FORCE duplicate-symbol race over the REAL QPC clock in
L4TIME.cpp (LNK4006). Every Now()-domain consumer (dead-reckon above all) ran
on call-count pseudo-time. Removed TIMESTUB from the build; L4TIME covers every
symbol. [The real clock alone did NOT cure the chop -- but it was objectively
broken and un-gated the two latent bugs below.]
2) TWO CRASH FIXES the real clock exposed:
- legAnimationState@0x3b0 never ctor-initialized (the task-#56 0xCDCDCDCD
family): the type-3 writer re-dispatches SetBodyAnimation(legAnimationState)
on the WRITER; a record emitted before the leg SM's first tick passed raw
0xCDCDCDCD as a clip index -> AV (cdb-pinned, mech2.cpp:233). Init 0.
- Replicants were SERIALIZING update records: the tail WriteSimulationUpdate ran
for every instance, and the port's replicant leg-SM accommodation (task #50)
calls ForceUpdate -> replicants emitted derived/uninitialized state into the
stream. Master-gated; replicant marks discarded (master-authoritative).
3) THE CHOP ITSELF: the master's resync send-gate compares localOrigin vs
projectedOrigin -- the PEER-ESTIMATE mirror -- but the port master never
maintained projectedOrigin (the bring-up drive replaced Mover::Perform; the
engine only updates the projection inside replicant-only DeadReckon). Stale
mirror -> |local-projected| > deadband EVERY frame -> a type-4 re-base record
EVERY frame -> the replicant hard-copied the master's deadband-quantized
heading each frame (the engine lerp never engaged; nextUpdate always behind
till) -> stall/snap beat = the chop. FIX: advance the mirror each frame by the
last-SENT angular velocity (what the peer is extrapolating) and re-base it in
the type-4 writer. Records now flow only on TRUE drift (~1 per 5 frames in a
steady spin), the replicant extrapolates smoothly between them, and the lerp
horizon finally engages. Measured: STALLS 13%->1%, JUMPS 11%->1% (residue: tiny
sub-degree backward corrections on record arrival -- inherent dead-reckon
overshoot the lerp absorbs).
Diag probes: BT_REPL_HDG (per-frame replicant heading + dead-reckon internals),
BT_REPL_TRN (replicant turn/leg state). scratchpad/clockcrash_bp.txt (cdb).

Locomotion: wire the AUTHENTIC per-mech turn-rate lerp (task #64b)
The master-perf disasm (0x4aa3d3-0x4aa4ff) computes the yaw rate as lerp(walkingTurnRate@0x574, runningTurnRate@0x578) by ground speed, not a constant. Wired it into the drive, replacing the bring-up constant kDriveTurnRate: - walkingTurnRate/runningTurnRate are now REAL named members. The ctor's `Wword(0x15d)/(0x15e) = model->...TurnRate * DegreesToRadians` writes were NO-OPS -- Wword() returns a shared static scratch cell, so the rates were silently discarded. Now stored + read by name. - The drive (mech4.cpp) computes authTurnRate: base = walkingTurnRate; above reverseSpeedMax(0x538) lerp walk->run across [walkStride 0x534 .. topSpeed 0x34c] with an over-run falloff runningTurnRate/t^2; clamp >=0; zeroed in the death/limbo/airborne leg states (1/2/3) or when deathAnimationLatched(0x650) is set. Falls back to kDriveTurnRate if the model gave no rates. The lerp is a RUN-speed refinement -- below reverseSpeedMax (walk / turn-in-place) the rate is the constant walkTR base; runningTurnRate < walkingTurnRate (a running mech is less maneuverable). Verified headless (DEV mech, BT_TURN_LOG): walkTR 1.309 rad/s (75 deg/s), runTR 0.873 (50 deg/s), turn-in-place + walk yaw at walkTR, no crash.

Damage economy RECONCILED: 3 stand-ins fixed, 3 paths confirmed authentic (task #60)
Full 5-path audit of the damage economy vs the decomp (5-finder + adversarial-verify workflow), resolving the KB self-contradiction the binary-coverage audit flagged. CONFIRMED AUTHENTIC as-is (no change needed): - Energy beam (emitter.cpp): damagePortion = authored DamageAmount x (charge/seekV)^2; the ctor x1e7 and fire x1e-7 cancel (_DAT_004bafbc dumped from the exe = x87 80-bit 1e-7 exactly). - Autocannon (projweap.cpp): full authored DamageAmount from resource +0x19C delivered unmodified; the 0.0625 at :667 is the shooter's own gyro recoil, not the round. - Zone-armor BASE model: damageLevel += amount x damageScale[type] (engine DAMAGE.cpp:379, called mechdmg.cpp:427), legs x0.5, 1.0=dead. 3 STAND-INS FIXED (all byte-verified against the decomp): - A. mechdmg.cpp:451 -- read the phantom `stance` member (no binary offset, zero writers -> perma-0), so the leg-shot-out -> fall/death branch was DEAD. Now MovementMode() (mech+0x40, @part_012.c:6910). - B. mechdmg.cpp:458 -- guarded the leg partial-failure graphic on the always-0 IsAirborne() stub where the binary calls IsDisabled() (@0049fb54 = movementMode 2||9). On a wreck the binary SUPPRESSES the write; the stub let it corrupt graphicAlarm 9->4/3 -- the task-#52 wreck-graphic bug, now fixed AT SOURCE (was only masked by the IsMechDestroyed latch). - C. mech4.cpp:1551 -- flat kShotDamage=12 fed as the kill-score damageAmount (the KB self-contradiction: task #8 claimed it retired, but it was live). The score handler @0x4c02e4 derives the whole kill award from it, so every kill scored identically regardless of weapon. Now lastInflictingDamage -- the real killing-blow magnitude, latched in TakeDamageMessageHandler (mech.cpp:624), mirroring the per-hit path (mech4.cpp:1207). The phantom `int stance` slot is reused for the new Scalar member (size-neutral, no layout shift); init 0 in the ctor. DEFERRED (task #60-D, documented): the missile CLUSTER model -- the port fires N flying rounds (net armor total authentic) vs the binary's ONE missile with a random burstCount cluster roll (loses cluster variance + single-zone concentration). Blocked on an OPEN decomp semantic (does burstCount multiply armor or only the gyro kick? settle at FUN_004bef78 -> FUN_004be078 -> EXPLODE.cpp:209-210). VERIFIED live: clean build; 2-node fight -> clean center-mass kill (no crash, kills 0->1); [zone-armor] dump confirms per-zone armor 50-140 + legs x0.5. NB the displayed POINTS score still reads 0 -- a SEPARATE open gap (scoreAward + role/team/tonnage multipliers unwired); fix C corrected the damage INPUT to that formula. KB swept: open-questions.md (self-contradiction resolved + task #60 summary + deferred missile item), combat-damage.md (damageScale is type-indexed not even/odd; task-#52 source fix; kill-score section), RECONCILE.md (missile = ONE spawn not N), stale comments in mechweap.cpp (SendDamageMessage is LIVE), mislanch.hpp, mechdmg.cpp (FUN_0049fb54 = IsDisabled).

Gait: the AUTHENTIC walk lean -- interior/exterior clip sets, level cockpit + leaning mechs (task #59)
The MadCat (and every leg-mech) leans -8deg into a walk / -11deg into a run --
an authored jointhip (hingex) pose in the EXTERIOR gait clips that the walk/run
CYCLE clips never rebind, so it HOLDS. The 1995 game keeps a separate INTERIOR
('i'-suffix) clip set for the mech you PILOT: those shake jointshakey (cockpit
rattle) and OMIT jointhip, so your own view stays level while everyone else sees
you lean. The port had this entirely dead -- the local cockpit mech pitched
-8deg into the ground (user-reported "staring at the ground").
ROOT CAUSE (two stacked bugs):
- The authentic ctor clip-set gate (@part_012.c:10308-10320) was reconstructed
as no-op stubs: LoadLowDetailBody/LoadHighDetailBody MISLABELED the
FUN_004a80d4/86c8 GAIT-CLIP loader addresses as a "body LOD" pair, so the gate
did nothing and a separate unconditional LoadLocomotionClips always loaded
EXTERIOR clips.
- LoadLocomotionClipsExt (the interior loader) was a stub aliased to the
exterior loader.
FIX:
- Reconstructed the real 4-char INTERIOR loader (byte-exact vs @004a86c8; the
'i'-suffix table dumped from the exe @0x10d74d: swri/wwri/wwli/...; all 18
base clips confirmed present in BTL4.RES for mad/blh/ava).
- Fixed the ctor gate: getenv("L4VIEWEXT") || (instanceFlags&0xC)==4 -> exterior
(replicant / forced external view); else -> interior (local cockpit master).
Removed the mislabeling no-op stubs.
- PORT ADAPTATION (MaintainViewClipSet, per-frame in PerformAndWatch): the port
never sets the replicant COPY bit (all MP mechs build as local masters --
heat-sim/scoring/torso-watcher-connect all run on both, by design), so the
ctor gate lands everyone on interior. Pick the set by VIEWPOINT instead: the
mech you pilot keeps interior (level cockpit), every other mech flips once to
exterior (the lean). Reloads only on a viewpoint-status change; the sets
share stride data so the swap is seamless. Model pointers stashed at ctor.

Torso: the TWIST goes LIVE -- electrical watchdog chain, centered crosshair, coherent controls (task #57/#58)
The MadCat torso twists, the view turns with it, and targeting follows. Three reconstruction fronts closed: THE ELECTRICAL WATCHDOG CHAIN (why the torso never powered up): - PowerWatcher::UpdateWatch reconstructed (@004b181c, the REAL registered Performance -- PTR @0050f5fc; Ghidra missed the fn start): the watchdog MIRRORS the watched subsystem's electrical level (+0x278), brownout downgrade when gen output <= minVoltage% x rated. @004b1804 relabeled ResetToInitialState (slot 10) -- the old "Simulation" tag was wrong. - The factory watcher-CONNECT pass reconstructed (vtable slot +0x38, @004aee2c/@004b1a40 byte-identical, recovered from raw exe bytes): watchedLink.Add(roster[watchedSubsystem]) on the master node. Was the SubProxy::Start() no-op -- every watchdog sat at 0 forever. - MinVoltageScale = 0.01 (a 10-byte x87 literal @0x4b1924; was 1.0f = permanent brownout) and PowerWatcher's Derivation chains its REAL base HeatWatcher (the HeatableSubsystem stand-in broke IsDerivedFrom for the whole Torso/Searchlight/ThermalSight family). - KB correction swept: derivation tag 0x50e604 = HEATWATCHER (not "HeatSink"); the btl4gaug heat-widget gate now tests it via the BTIsHeatWatcher bridge. THE CROSSHAIR (task #58 forensics, 6-agent workflow + live probes): - The VIEW is TORSO-MOUNTED: jointtorso -> jointeye -> siteeyepoint in every twist-capable .SKL; the camera + canopy ride the same hinge subtree through HingeRenderable's live matrix-stack compose -- ALREADY WORKING in the port. The crosshair stays screen-centered (center IS the boresight); the twist reads on the tape carets/compass/radar. - The real bug was the port's gBTAimX = tan(twist) slew (the falsified "body-mounted view" model): the camera already carried the twist, so the crosshair counter-slid to hull-forward and the fire ray with it. Deleted; the pick ray inherits the twist from the yawing eye basis. - Two instrumentation traps documented (chase-eye-as-default-camera, BT_FORCE_TORSO clobbering real joints -> the hook now only fills unresolved ones); an over-correcting explicit eye compose was added on those false readings and retired the same day. CONTROLS + REPLICATION: - Q/E spring-center on release (the axis is a twist-RATE demand; the old hold-deflection model drifted forever); X also zeroes the axis and pulses the authentic torso Recenter (@004b6918). M cycles control mode via the real CycleControlMode body. - Torso update-record DIRECTION fixed: engine truth is Write=serialize / Read=apply; @004b6a78 is the READ (was mislabeled Write) and the missing WRITE @004b6a1c recovered from raw disasm (recordLength 0x1C, twist/vel/rate at +0x10/14/18) -- kills the replicant's 0xCDCDCDCD -140-degree ghost twist. - Marching-ghost desync: 4 Standing-case guards zero stale reverse cycleSpeed (negative cadence passed the <= ZeroSpeed stop gate). - Kill credit rerouted to the OBSERVED killer (lastInflictingID -> killer's player link) -- kills count, target K/D populates. KB: subsystems.md (watcher chain), multiplayer.md (record direction), combat-damage.md + gauges-hud.md + cockpit-view.md (torso-mounted view re-correction), decomp-reference.md (new addresses + tag fix), open-questions.md (dead capability-roster loops 2-4, snapshot CD read).

Impact-FX FORENSICS wave: the i860 specialfx engine, per-round detonations, the ram economy closed
The "we're off the rails" reinvestigation -- a 5-thread evidence workflow
(logs / PFX data / RES model lists / decomp / port audit) + the i860 firmware
decode, then surgical fixes. Every claim tiered; the wrong turns are on the
record in the KB alongside the corrections.
THE OLD-STYLE SPECIALFX ENGINE [T1, firmware-decoded from VREND.MNG]:
rebuilt scratchpad/i860dis.py (binutils opcode table); mapped the dispatch
(data+0xdd0c; sfx trigger 0xf040cda0, install 0xf040cdc0, step ~0xf0413698,
instance init 0xf04128d8); decoded the heat model EXACTLY: per 30Hz board
frame h *= cool_a; RGB_ch = h_old*(h_new*cook_ch - 0.25) + 0.25 (K=0.25 =
the ember floor @VA 0xF080; kill at h <= 1e-4 @0xF0A0); alpha fades cool_b
x RAW dt (PER-SECOND -- the x30 scaling made laser hits invisible); 7s cap;
y_off = the kill plane; "variance" is DEAD DATA (binary reads "variance",
INI authors "varience"). The 13 descriptors (PPCHit/LaserHit/MissileHit/
Chunks/Sparks/Fireball...) parse from BTDPL.INI and render via the BTPfx
layer -- heat bursts draw the FIERY sheet (brightness over fire), .PFX keeps
GRAYSCALE (authored colours: DNBOOM orange, DDAM gray).
HIT-PACKAGE CENSUS [T1, RES byte-verified]: ppchit=[8] lzrhit=[9] mghit=[7,11]
canhit=[11] mslhit=[10,12,1023] explode=[6]; all 8 mech death lists identical.
Effect routing corrected in BOTH consumers: <100 = specialfx, >=1000 = psfx.
"SILVER MIST x5" ROOT CAUSE: SHKWAVE.PFX (mslhit's 1023) authors maxIssue=5
relPeriod=0.2 rate=1 -- the ONE file where rate contradicts the window; the
emitter trusted rate -> 5 shells at exactly 1Hz. Emission rate now always
maxIssue/releasePeriod.
PER-ROUND DETONATIONS [T1 @004bef78]: every missile round spawns its own
ExplosionModelFile at ITS impact (hull + terrain) -- a volley ripples 12
fireballs like the demos; rack-tube launch spread [T3] (GUIDED rounds only --
the slot-0 deflection sent every AFC100 shell 3.4deg left/2.5deg down: the
phantom "4th gold beam"); replicant salvos detonate too (launcher index rides
the visual push). Missile damage bundles through the shooter's messmgr with
the launcher's subsystemID (mslhit fires at the consolidated point; the
binary's dedup CONFIRMED [T1 @0049b784] -- a workflow agent's per-record
claim REFUTED by direct decomp read).
DAMAGE-BAND SEMANTICS [T1]: MechDeathHandler fires the CURRENT band effect on
any damage rise (the binary's changed-flag coalescing) -- a mauled mech under
fire smokes/burns per hit; bands 3/4 are authored fire plumes.
THE RAM ECONOMY -- CLOSED (3 layers, measured live):
1. armor = POINTS (every zone: damageScale = 1/armorPoints, armor 50-140;
the [zone-armor] BT_DMG_LOG dump);
2. StaticBounce prices rams with authored moverMass ~1.3e6 -> ~59,000 pts
@10m/s; the binary dispatches it RAW but pod MP dropped it on the local
replicant (MECH.CPP:986 warns) -- ram damage was NETWORK-INERT; our
task-#47 replicant forwarding surfaced it as a one-shot. Port
normalizes x1e-3 to the point economy [T3];
3. contact EDGE (ramLastVictim/ramContactLinger): the binary's bounce made
separation implicit; our gait-derived velocity re-priced full rams at
60Hz (the respawn explode-loop). One bump = one hit; pressed = BLOCK.
PLUS: sfx size x0.5 + 1.25m visibility floor + hot-phase occlusion [T3];
particle pool 2048->8192 (missile traffic starved laser bursts -- the
"intermittent effects"); replicant beam aging (a lost beam-END record pinned
a stale beam on forever); UV-variant noise stamps (mask-safe mirror/swap);
no scroll on particle stamps (material-path only); BT_FX_TEST/fxshot.py
self-verification harness ([beam-draw]/[zone-armor]/[collide-tx] telemetry).
KB: rendering.md (specialfx engine + census + closeout), combat-damage.md
(ram economy + band semantics).

MP live-play wave: collision economy, missiles, radar transform, panel polarity, comm ticker
The interactive 2-node playtest wave -- every fix decomp-grounded and live-verified: COLLISION ECONOMY (the ram one-shot): StaticBounce mutates worldLinearVelocity per contact and ProcessCollisionList walks EVERY touched solid per frame; with 2007 terrain-as-solids the reflections compounded x4-x40 within one frame and a walking bump one-shot a pristine mech for 112,375 pts (62-pt authentic economy). Fix: frameEntryWorldVelocity restore per contact (damage always priced at the real approach speed -- all the binary's physics ever saw); Mech::Reset zeroes the mover motion (respawn = teleport); [collide-tx]/[mp-hdlr] telemetry. Gotcha #16 (engine-facility drift class). MISSILES: peer-visible salvos (the launcher record extension carries a salvo counter + aim point; ForceUpdate actually enqueues it -- the dirty flag alone never serialized), the authentic arc (authored MuzzleVelocity vector + the Seeker's 200m/0.1/300 loft + gain-4 steering, decoded from @004beae4/@004bef78), world-impact bursts (rounds detonate on cave geometry instead of phasing through), contact-only damage (flight-cap expiry = fizzle, no more teleport damage), live re-lead, and ballistic (unguided) shells for autocannons. projweap's stale BTPushProjectile extern (the /FORCE signature trap, gotcha #6 corollary) crashed the Avatar's first AFC100 shot -- fixed + sweep rule recorded. RADAR: two transcription bugs made the scope permanently empty -- FUN_0040b244 is the affine INVERSE (not a copy) and FUN_0040adec writes ONLY the 3x3 rotation (never the translation); worldToView now Invert(view) built rotation-first. CulturalIcons sorted out of the moving grid (the phantom red pips were map props), visible-radius culls on all three draw passes, live pip verified at |delta| x ppm px. Gotcha #17 (verify the FUN_ body, not its call shape). WEAPON PANELS (the frozen-dial hunt): the binary's *(subsystem+0x40) means FAILED -- the recon's 'operating' name was backwards, inverting the destroyed-X lamps, the panel look, the children enable and the ready-lamp gate (which had NEVER executed). Polarity chain corrected end-to-end (failedState, fed by real damage saturation). Root cause of the freezes: MFD page-mode gating -- the dev composite shows ALL pages at once, so off-page dials legitimately stopped; under BT_DEV_GAUGES the 15 page-plane bits stay active (the exclusive secondary trio untouched). The SEH gauge guard now names its kills; repaint-heal resets the incremental arc after panel repaints; [panel]/[arc] probes added. COMM/SCORE: MessageBoard LIVE (the engine already shipped the whole Player__StatusMessage queue; wired the binary's one producer -- the kill branch, victim's name, 6s -- plus the consumer bridge and a lazy source bind); MP DEATHS counted via the observed-death tally (each node scores every pilot from locally observed events, the same model as the KILLS credit) and the -2/-1 engine seed clamped for display. DEV UX: node-tagged window titles (-net port), gauge panel reworked (1320x480, true 4:3 MFD cells, the portrait secondary UNROTATED upright, linear filtering, BT_GAUGE_SCALE), fixed close spawns via BT_SPAWN_XZ, Boreas flies an Avatar (first second-chassis live outing).

Mech: THE 0xBD3 UNTANGLE -- real SubsystemMessageManager in [0x10d], the mapper's one true home is roster slot 0 (task #7)
Binary census [T1]: mech+0x434 has exactly 2 writers (ctor init + factory case 0xBD3) and ONE reader (@0x4b984b in MechWeapon::SendDamageMessage @004b9728) -- pure message-manager semantics, nothing mapper-like. The factory case now builds the real SubsystemMessageManager (ctor @0049bca4, 0x130, ConsolidateAndSendDamage Performance); the misbuilt MechControlsMapper squatter is evicted. Every mapper consumer re-pointed to MappingMapper() (roster slot 0 = the binary's **(mech+0x128); SetMappingSubsystem @0049fe40 touches ONLY slot 0 -- its [0x10d] mirror removed). Non-viewpoint mechs get a slot-0 demand LATCH (base mapper, [T3] accommodation -- the binary leaves slot 0 NULL off-viewpoint but never drives/animates those paths; ours does). Verified: solo drive+gait clean; MP replicant gait through the latch (full run lifecycle); 3x kill/respawn cycle with type-6 records on the observer. Remaining (task #7 tail): the messmgr's consolidated TakeDamageStream send + weapon-path routing (@004b9728 real body). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Model record: the authoritative 200-byte overlay -- struct skew fixed, floor-25 era retired (task #4)
Two size errors (animationPrefix char[12] vs 4 bytes; a FICTITIOUS 64-byte skeletonName block -- the record has no skl name) skewed every member after word 0x10 by +2/+15 words and pushed the fieldXX block past the record end. Full writer map recovered (FUN_004a2da8 + Mover FUN_004238bc + Reticle FUN_00435ac8 chains) + runtime reader map (ctor pass @0x4a24d1-0x4a2968, capstone-verified). Struct rewritten as the exact overlay (static_assert- locked); all Pass-2 consumers renamed to real fields; retired: ctor + replicant + master-gait floor-25 hacks, the throttle guard, the fictitious classID stamp. Verified: accel=30 superStop=10 throttleAdj=1 (was ~1/OOB/0), deadbands byte-identical via named fields, full walk->run lifecycle clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

MP: authentic update-record deadbands streamed from the model record (task #3)
Binary ctor @0x4a26a7-0x4a26ef: mech+0x768/76c/770 <- raw record words 0x26/0x27/0x28 (UpdatePositionDiffrence / UpdateTurnVelocityDiffrence / UpdateTurnDegreeDiffrence x pi/180 [const @0x4a2d44]). Read at RAW record offsets -- the Mech__ModelResource struct is layout-skewed (field98 gave -1.5 where the record holds 0.3; audit filed as task #4, also explains the old forwardCycleRate "floor 25" hack). Sender triggers now use the authored constants: pos-deadband type 0, quat-Y delta + yaw-rate delta + stopped-turn edge type 4 (binary @0x4aad35/@0x4aac2b/@0x4aac6c). Verified 2-node: madcat streams 0.3/0.045/3deg, type-4 spam gone, walking replicant clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

- Writer transcribed from the recovered disasm; reader rewritten from part_012.c with every Wword absorber promoted to named engine/port members (updateOrigin/updateVelocity/projectedOrigin/projectedVelocity/nextUpdate/ lastUpdate + bodyTargetSpeed/latches/alarms). Wire sizes verified live: 0x14/0x20/0x2c/0x78. - movementMode UNIFIED with Simulation::simulationState (binary mech+0x40 = StateIndicator@0x2c currentState) -- death/limbo/airborne now replicate in every record header. Three mislabels of the same binary fns retired: SetInstanceFlags + RequestActionFlags -> Mech::ForceUpdate (updateModel |= mask, 0xfe03 disabled filter); IsNetworkCopy -> IsDisabled. - Senders wired byte-exact: gait transitions Force(8), knockdown Force(1|0x20), death Force(1|0x40), Reset Force(0x1f) + binary zero-set, perf-loop deadbands (speed type 2, orientation type 4, heat type 7). - 2-node verified: types 2/3/4 flow while driving; kill -> type-6 record (simState=9) -> the OBSERVER's replicant runs the wreck sink loop with no double death transition; respawn 0x1f burst snaps + un-wrecks the peer; walking replicant un-regressed (run 12, cycle tracking); solo clean.

Gyro: damage fan-out FUN_004b2980 -- the cockpit hit-BOUNCE is live (task #56)
Re-disassembled the unexported gap 0x4b2980-0x4b2d8b byte-exact (capstone over
section_dump.txt) and reconstructed Gyroscope::ApplyDamageResponse:
- zero-damage + Collision(type 0) no-op; hit direction = Damage::damageForce
or a RANDOM horizontal fallback when ~zero (per-component sign roll then
value roll -- binary-legal until senders fill damageForce)
- direction rotated by the yaw-only torso-twist frame (placeRot=(0,twist,0)
-> euler->matrix, the FUN_00408744 raw row-dot reproduced verbatim)
- per-type scaling amount / damageMultiplier[type] * damageResponse[type]
.{trans,pitchRoll,yaw,vibration}; Explosive alone multiplies burstCount;
each clamped at 1.3f
- four kicks: impulse(trans, dir), torque(pitchRoll, dir), impulse(vibration,
vibrationDirection@0x390) and verticalImpulse(yaw, dir)
Layout corrections (byte-verified): gyro+0x390 is ONE Vector3D vibration axis
init (0,1,0) -- was mis-split as scalars animationOffset/Scale/Phase; mech
+0x5c4 is a FLOAT rumble-period countdown (gyroRumbleTimer) -- was mis-typed
int clipLoadGuard.
Call sites wired (binary-gated):
- take-damage hub: mech.cpp TakeDamageMessageHandler, FIRST action (@0x4a0264
in hub FUN_004a0230) -- an invalid-zone hit still bounces
- crushable-icon crunch: mech4.cpp, torque 0.4 along the bounce delta-v + up
impulse 0.2 (@4aa81e/@4aa86c)
- firing recoil: projweap.cpp FireWeapon, damage>3 -> impulse (0,0.6,-1.5)
x damage/16 (@4bc136-4bc19c) via the new Mech::GetGyroSubsystem accessor
DEFERRED (recorded in KB with the byte recipe): the alternate-gait engage
jolt + 0.4s rumble (@4aa158-4aa365) -- its gates are [T3]-flagged and it
mutates the #49/#50-stabilized gait machine.
Verified live: [gyro-dmg] fires per hit with correct type scaling; eyePosition
shows the damped bounce (ramp to ~0.015u, oscillating Y, decay to zero); kill
chain un-regressed; no NaN.
Also recorded in KB: the OFFSET-COCKPIT verification -- Thor's authored
jointeye tranx=+1.13 matches its canopy X-center exactly AND our in-game eye
reproduces it to the hundredth (the placement model is correct per-mech); and
the playable roster is 8 models (strider/raptor/firstrtr/blkjack have assets
but no model resource -- BT_FORCE_MODEL with those names = NULL-resource AV,
cdb-verified, not a code bug).

Gyro: byte-exact re-enable -- ctor map, integrators, jointeye writers (task #56)
The Gyroscope subsystem is LIVE again (was a stub since the NaN revert).
Reconstructed byte-exact from @004b3778 / @004b2ec0 / @004b30ec / @004b33e0 /
@004b34ec + the byte-verified dispatch in the unexported Mech performance
FUN_004a9b5c (calls @0x4aaf74/0x4aaf83):
- ctor field map corrected: springConstant@0x1E8 / dampingConstant@0x1F4 were
mislabelled (the old 'eyeOrientation = r->springConstant' poison line), the
0x254-0x2B3 block (externalPitchPtr, work matrix, placement) was missing so
everything after was mis-offset, and clamps/accumulators were 0xCD fill --
every field now initialised per the binary; 33 offsets static_assert-locked,
sizeof == 0x3D0 exact
- integrators: state-minus-target displacements, componentwise damping
OVERWRITE (FUN_004086d0 is a component multiply, not a cross), position step
without dt, clamp to [posSpring, negSpring]; IntegrateBody's X/Z-crossed
force + integration terms
- writers: WriteMechJoint drives ONE node ('jointeye', type 5): TRANSLATION =
eyePosition spring, ROTATION = bodyOrientation spring; WriteEyeJoint is a
multiplicative sway attenuator on 'jointlocal' (post-anim only)
- dispatch moved out of GyroscopeSimulation into the Mech performance tail
(GyroFrameJointWrite bridge, mech4.cpp) with the binary gates; gyro<->torso
pitch link wired (gyro+0x258 = &torso currentTwist) via complete-type-TU
bridges, retiring the SubProxy::linkTarget landmine
- Mech ctor: deathAnimationLatched/legResetLatch were never initialised --
0xCDCDCDCD gated the writers off silently
Runtime-verified: joints resolve (both BallTranslation), Performance installs,
WriteMechJoint finite from frame 0 (no NaN), Madcat cockpit un-regressed,
combat targeting healthy. Empirical: spring targets are SYMMETRIC -> eye
equilibrium (0,0,0), clamps +/-0.1-0.15u -- the gyro is the hit-BOUNCE
mechanism, not a steady eye offset (hypothesis disproven, recorded in KB).
Pending (task #56 tail): the damage->gyro fan-out FUN_004b2980 (unexported
gap) so hits actually kick the springs; the mech+0x3F0 overspeed sway model;
the torso-pitch EyepointRotation writer (FUN_004b66b4) + glance-look states.

Shadow: authentic terrain tilt + decal draw order (feet layer correctly)
User report: the ground shadow painted OVER the mech's feet. Root cause: the
flat quad + big depth-bias (-0.004 ~= 2-4 world units) workaround for slope
burial -- a bias big enough to beat the TERRAIN also beat the FEET in the
depth test, and the shadow drew in the late alpha-blend pass (after the mech),
so z-arbitration was the only layering control.
Fix, four co-dependent parts (user-verified live: feet on top, opaque,
survives inclines/declines):
- TILT (mech.cpp UpdateShadowJoint): apply the SKL's own contract for
jointshadow ("apply terrain angle to pitch and roll") -- quad up aligned to
the surface normal via an orthonormal basis fed to the ENGINE's own
LinearMatrix->EulerAngles conversion. Hand-derived Euler signs are exactly
how the prior tilt attempts "dug into the hillside"; the engine conversion
is convention-proof. ~35 deg cliff-guard cap.
- SAMPLER (mech4.cpp): surface gradient from the collision probes PLUS
BTVisualGroundLift per probe -- the quad hugs the VISIBLE terrain, whose
lift varies across a slope; world->local rotation by the TRUE yaw from
localToWorld, not the drift-prone gDriveHeading mirror (the task-#48 bug
class). BT_SHADOW_LOG traces the normals.
- DRAW ORDER (new PASS_SHADOW, l4d3d.h/L4VIDRND/L4VIDEO): shadows draw
between the STATIC terrain and the DYNAMIC opaque bodies -- the classic
decal order. The mech, drawn after, z-passes over the shadow: the bias
can never paint the shadow over the feet, structurally.
- BIAS pairing (L4D3D.cpp): tilt on (default) -> decal epsilon -0.0008;
BT_SHADOW_TILT=0 flat fallback -> the old -0.004. BT_SHADOW_BIAS overrides.
KB (locomotion.md): the four-part arrangement recorded as co-dependent, with
the gait-desync-symptom diagnostic hint retained.

MP task #47 SOLVED: cross-pod damage + kill (validate the master mech)
Full cross-pod KILL now works: instance A (host 2) shoots B's mech (host 3) dead over the network; B runs the death transition on its own screen. Verified on a 2-node one-box run (BT_MP_FORCE_DMG on A): B's mech takes ~36 remote hits of 12 and is DESTROYED, with wreck swap + explosion. ROOT CAUSE (one bug): B's own MASTER mech was INVALID. Entity::Receive(Event*) does `if(!IsValid()) event->Defer()` -- so a cross-pod-delivered TakeDamage that arrived, resolved to B's real mech, and Posted, was DEFERRED forever; the handler never ran. The reconstructed Mech::Make force-set ValidFlag only for replicants (the P6 bring-up hack for the partial MakeReady handshake); a locally-created master never got validated. FIX (one line): Mech::Make now sets ValidFlag for the master too -- the reconstructed ctor builds the mech synchronously, so it's safe. Nothing else changed: targeting, the virtual victim->Dispatch, the replicant reroute, the wire, receive, and id resolution were ALL already correct. Two prior root causes were BOTH mis-diagnoses from the WRONG messageID: Entity::TakeDamageMessageID is 18, not 21. Every earlier probe filtered msgID==21, never matched a real TakeDamage, and mis-correlated the stray 21 hits' 3:19 / classID-48 against the real 3:22 hit -- inventing (a) a "cross-TU Entity layout divergence" (disproven: offsetof identical in both TUs, sizeof 444, entityID@0x17C) and (b) a "localID corrupted on the wire". Both FALSE; the id is correct end-to-end (3:22 = B's master). - game/reconstructed/mech.cpp: validate master + replicant at Make. - game/reconstructed/mech4.cpp: BT_MP_FORCE_DMG cleaned to a concise gated 2-node cross-pod reproducer (real virtual Dispatch path). - context/multiplayer.md, reconstruction-gotchas.md: corrected root cause + the validity-defers-cross-pod gotcha. Engine diagnostics reverted to clean. Solo un-regressed (the solo enemy was already force-valid; the change only ADDS ValidFlag). btl4.exe builds; full mission loop clean.

MP cross-pod damage ROOT-CAUSED: EntityID localID corrupted by hostID on the wire (task #47)
Traced the dispatched-message delivery end to end with BT_MP_NET / BT_MP_FORCE_DMG. Everything works except one wire step: - A's Entity::Dispatch reroutes the replicant's TakeDamage (application->SendMessage(ownerID=3, EntityManager, msg)); POST-Dispatch the message carries entityID=3:22 (host:local) -- the replicant's own ID, matching B's master (GetEntityID()==3:22). VERIFIED sent. - On B the message ARRIVES, GetEntityPointer finds an entity, Posts it, the event drains (ProcessEventTask = ProcessOneEvent(0)), Event::Process runs, Receive finds+calls a handler. VERIFIED the full deliver chain. - BUG: B receives entityID=3:19, NOT 3:22 -- the localID dropped by exactly the hostID (3) between A's send and B's receive. So GetEntityPointer(3:19) returns the WRONG entity (classID 48, not the mech 0xBB9), whose base handler ignores the unaimed hit -> 0 damage. Auto-replicated UPDATE records (msgID 18) arrive with the correct 3:22 and find the mech, so the corruption is specific to the dispatched- message wire path/direction. Next: the host-relative EntityID (de)serialization on the dispatched-msg path (RoutePacket / packet EntityID encoding) -- diff vs the update path which translates correctly. Diagnostics retained (all BT_MP_NET-gated, off in solo -- verified: solo 22 hits, 0 probe noise). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

MP combat step 1 (target any peer) DONE; step 2 (cross-pod damage) localised (task #46)
STEP 1 -- target any peer mech: DONE + verified. A live-mech registry (BTRegisterMech/BTDeregisterMech from the Mech ctor/dtor) collects every mech -- player, dummy, and peer replicants. The boresight world-pick walks BTGetTargetCandidates (all mechs != shooter, closest ray hit) and the whole fire/damage block retargets from the solo gEnemyMech to the picked hotTarget; missile/projectile validation generalised via BTIsRegisteredMech. Verified one-box: instance A enumerates B's mech as a live ReplicantInstance (20 zones, ownerID=3). Solo un-regressed (pick->damage->kill clean, 28 hits + DESTROYED). STEP 2 -- cross-pod damage: dispatch + engine reroute are CORRECT and invoked with a valid owner, but the dispatched message doesn't reach the master. Entity::Dispatch (ENTITY.cpp:244) reroutes a replicant's msg via application->SendMessage(ownerID,...); BT_MP_FORCE_DMG proves A dispatches at B's replicant with ownerID=3, yet B takes 0 STEP-6 damage. Corrects the KB's [T3] "Dispatch already reroutes": the reroute FIRES; the break is downstream in the transport/delivery of a dispatched entity-message (update records flow fine -- net-rx works). Next MP task = that wire delivery. Diagnostics BT_MP_LOG / BT_MP_FORCE_DMG retained. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Reticle Execute @004cdcf0 RECOVERED: every HUD instrument now live (task #37)
The one un-exported gap in the reticle chain, read via capstone (tools/disas2.py; the annotated disasm preserved at reference/decomp/reticle_execute_004cdcf0.disasm.txt). Draw() is now a transcription of the real per-frame logic, and the HUD attr-table names (hud.hpp ids 4/5/6/8/A/B/C/D) are CONFIRMED by their Execute usage: - Range ladder: BAR from ladder-top to the caret + caret translate. - The bottom 21-tick tape is the TORSO-TWIST indicator (NOT heading): deflection = -/+(span/2) x (RotationOfTorsoHorizontal / twist limit), attrs 4/5/6. Fixed-torso BLH reads centred -- authentic static. - The circle-with-stem is the COMPASS (attr 0xD, rad->deg rotation) at (botX, botY - 3*tickMajor - 0.03), with the THREAT trail (attr 0xC) in its rotated frame: 0.05-unit attack-direction marks, fresh < 2s red, expiring at 6s. Port feed: player TakeDamage pushes the impact direction (dormant vs the passive test dummy). - Pips (composed into subB6): hidden when destroyed (attr 1 == 1), LIT when the fire cycle is LOADED (attr 0x1c == 2; port source rechargeLevel >= 1) else the dark charging ring; filtered by the weapon-GROUP bits (weaponMode & elementMask&0xF). Range plays NO part (the stored TargetWithinRange slots are never read by Execute). - Lock ring: subB9 at frame centre SPINNING 4 deg/frame while locked ([0x9d] is the spin matrix, not a heading list). - Target HOTBOX: a rectangle hugging the projected extents (x+-4 around the top-centre hotbox point, +1/-11.5 vertical; baked K=2.8145 -- the port projects through the live per-axis projection), switching to the edge arrows past +-1.6 or behind (BTProjectHotBox, L4VIDEO). - Reticle state Off/On + PrimaryHudOn full-HUD/simple-X switch, aim translate on slew move, 3D marker + PNAME player-name mesh identified (chain still deferred).

Authentic target acquisition LIVE: reticle slew + pick-ray lock + aimed zone damage (task #36)
The engine Reticle model (MUNGA/RETICLE.h [T0]) reconstructed end to end: - Mech::targetReticle is a real Reticle member bound to the TargetReticle attribute (0x1d), per the RP VTV analog (VTV.h targetReticle). - Crosshair slew: mouse -> client rect -> reticle coords (the pod stick free-aim channel's dev-box stand-in); BT_AIM="x y" pins it headless. LMB fires lasers / RMB missiles (alongside SPACE/CTRL). - Pick ray: the ACTIVE eye publishes pos + LookAtRH basis (BTSetAimCamera, L4VIDRND view-write site) + the render loop publishes proj._22; BTGetAimRay builds the world ray, Mech::PickRayHit slab-tests it against the collision template's ExtentBox via the engine's BoundingBox::HitBy (local frame; clips the Line at entry) -> world hull point. - Designation: the mech under the crosshair designates (sticky; re-hover refreshes; cleared when the target leaves the roster at burial); the entity target slots 0x37c/0x388/0x38c feed the whole weapon path. - Aimed fire: while HOT the impact point is the PICKED hull point -> the STEP-6 cylinder lookup resolves the zone under the crosshair (verified: center-aim -> head-band zone 13 dominant). Off-crosshair the sticky designation converges on center mass. - HUD: the aim group draws at the slewed position ([0x9a] translate, contained by push/pop); the designator ring tracks the target's projected point (subB9 hot / subB8 designated, BTProjectToReticle); edge arrows when off-screen/behind. - AUTHENTIC gating: no fire arc exists in the binary (FireWeapon fires whenever HasActiveTarget, part_013.c:7758) -> BT_FIRE_ARC is now an explicit OPT-IN presentation clamp; the hardwired gEnemyMech lock and the projectile path's gEnemyMech fallback are removed. - Fixed en route: every renderable rebuild stomped mCamera back to the chase eye (start-inside silently lost the cockpit camera; the aim feed exposed it). BTL4VideoRenderer::mViewInside persists the chosen view. Verified headless: BT_AIM="0 0" -> HOT lock, pick hits the hull face at exact range, aimed zones resolve; BT_AIM="0.8 0.3" -> no lock, zero damage, zero missile launches; kill chain completes to wreck + smoke.

HUD reticle + weapon pips LIVE: dpl2d 2D display-list port (task #35)
- dpl2d API fully recovered from the binary recorders (@487f34-488630): opcode model (points/lines/polyline/circle/color/width/matrix/push-pop), CallList = INLINE include (state persists to caller), centered coordinate frame (unit = half viewport height). game/reconstructed/dpl2d.cpp rework. - BTReticleRenderable ctor @004cc40c transcribed with the authentic calibration (originX .35, originY .25, scaleY .5, 0..1200m right range ladder, bottom heading tape, FUN_004cd938 tick ladders, lock rings, turn arrows); range caret slides from the live target range fed by the mech4 targeting step (BTSetHudTargetRange). - Weapon pips: the binary gate is IsDerivedFrom(0x511830 = MechWeapon::ClassDerivations) [T1: part_014.c:5386 hard-aborts on missing weapon attrs; part_012 counts + roster ORs capabilityFlags@+0x334] so ALL 7 BLH weapons register (3 lasers + 2 PPCs + 2 MissileLaunchers). Pip A (lit, authored PipColor) on TargetWithinRange, else dark ring B. - AddWeapon @004cdac0 store map corrected to the verified order (part_014.c:4827-4837); both state attrs are literally named "SimulationState" (strings @51d526/51d577) -> weapon simulationState. - Mech roster this[0x1ef] renamed poweredSubsystems -> weaponRoster (0x511830 is MechWeapon, not PoweredSubsystem=0x50f4bc); derivation-tag table added to context/decomp-reference.md. - Draw hook BTDrawReticle after the 3D scene, cockpit view only. Binary Execute @004cdcf0 is an un-exported gap -> Draw dynamics [T3], tracked in context/open-questions.md with the blx_cop canopy + PNAME pip meshes.

Cockpit view live: V toggle, camera gate, real EyepointRotation, inside skeleton
- V toggles the authentic cockpit eyepoint <-> the chase camera. Both eyes coexist; DPLEyeRenderable::Execute now writes the VIEW only when it IS mCamera (unconditional writes let the last-executed eye stomp the toggle). - EyepointRotation is a real zeroed EulerAngles member on Mech (was bound to the shared junk attrPad -- the eye composes this attribute into the view EVERY frame, so the cockpit camera was rotated by garbage: the canted horizon, then the black screen). The eye-slew systems write it later. - The cockpit eye mounts at the eyepoint's REST position with a clean upright forward basis on the tree root (the live joint chain fed it the site tilt + torso pose; authentic pitch/yaw is the deferred gyro eye chain). - The inside view swaps the player to the INSIDE skeleton mesh set (SkeletonType_A): 19 body segments hide, exactly one mesh remains -- blx_cop.bgf, the authentic cockpit canopy shell around the eyepoint. It currently renders as a black enclosure (the black-screen report), so it is HIDDEN pending its interior/punch-material rendering (BT_INSIDE_COCKPIT=1 shows it for that work). Damage gstates respected in both directions; RemakeEntity keys off the DISPLAYED skeleton. - Dev: BT_START_INSIDE=1 starts in the cockpit view.

PFX continuous-rate emission (data-verified) + persistent wreck smoke
The one-burst emitter batching was wrong: in EVERY shipped .PFX, maxIssue/rate == release_period (DAFC 25/100~=0.2, DNBOOM 35/150~=0.2, DDAM2 35/16~=2, DDTHSMK 30/3=10) -- release_period is the EMISSION WINDOW and rate is particles/second emitted continuously across it. The death smoke plume is authored as a 3/sec trickle for 10 seconds (+6s particle life), not one same-frame puff. Emitters now integrate rate*dt until maximum_issue. Wreck smoke (port addition, [T3]): a destroyed mech re-arms the death/rubble smoke plume (psfx 1, DDTHSMK) every 10s -- its own authored window -- so the dead hulk visibly keeps smoking instead of standing there looking alive (the freeze-death is invisible on an already-stationary target). New member Mech::wreckSmokeTimer; UpdateDeathState takes dt. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Combat visible + killable: Wword root-cause fix, .PFX effect layer, RemakeEntity swap
The 'can't kill the enemy / no visible damage' cluster, root-caused and fixed faithfully: - STEP-6 unaimed path was INERT: the cylinder table was 'cached' at Wword(0x111) -- the recon ABSORBER bank (stores nothing, reads 0) -- so every unaimed hit silently no-op'd. Promoted to the named member Mech::damageLookupTable (binary this[0x111], was mislabeled ammoExpended). New gotcha class recorded (reconstruction-gotchas §2) + sweep; 2 dead multiplayer branches logged. - Fire path migrated off the stale vital-zone aim onto the completed STEP-6 unaimed dispatch (zone=-1 + beam entry point -> cylinder resolves the exterior zone). No more invisible 1-shot kills; death via the authentic cascade (~14 center-mass hits). Wreck stays TARGETED on kill (beams stop on it); scoring latches off. - SendSubsystemDamage AV fixed: unbound critical-subsystem plug guard (43 unbound plugs/mech logged as an open question -- the binding itself is a gap). - RemakeEntity (render damage swap): the 1996 render state machine's missing Remake state, reconstructed as an in-place SetDrawObj mesh swap keyed by each segment's damage-zone graphic state (tree dtor doesn't cascade -> never rebuild). Destroyed arms/guns visibly wreck (the only variants the RES registers). - BT .PFX particle layer (L4VIDEO.cpp): the 1995 explosion/damage effect layer, unported since 2007 (DPLIndependantEffect/ReadPSFX/ExplosionScripts all stubs). Parses the authentic VIDEO/*.PFX definitions via the [pfx_day] psfxN mapping; premultiplied blending renders BOTH families from the same data (additive-style fire + occluding smoke -- DDAM2 is 30% grey, DDTHSMK ramps negative: impossible additively); depth-sorted billboards with a radial-masked grit sprite; impact-frame orientation (.PFX offsets are authored mech-local, -Z = out of the struck armor toward the shooter) for weapon hits AND damage bands (via lastInflictingID, now maintained -- was declared but never written). Both effect-number encodings route (raw dpl <100 + WinTesla 1000+slot carried by the band resources). Death fires the authentic dnboom (7) + ddthsmk smoke plume (1). - Effects anchor at the impact point / damaged zone's segment, not the mech origin (no more fire at the feet). - Dev force-input gates BT_AUTOFIRE / BT_AUTODRIVE for headless fire-chain verification; BT_PFX_ADD=1 flips the particle blend for A/B.

MechDeathHandler: per-zone destroyed-skins + explosions (faithful, exported)
Fixes the "kills are invisible" report: a mech died only at the state level, with no visible destruction on its body. Root cause: the per-zone damage-state descriptor table (binary zone+0xd4) that drives destroyed-skins + explosions was never built -- its loader (Mech__DamageZone::LoadCriticalSubsystems / FUN_0041e4a8) was a no-op stub, and MechDeathHandler itself was a no-op stub. The surrounding plumbing (the per-zone load loop over the type-0x1e resource, the death-handler slot) was already correct. Whole pipeline is EXPORTED -- no stand-ins. Reconstructed: - Mech__DamageZone descriptor table (binary this+0xd4): un-stubbed LoadCriticalSubsystems (FUN_0041e4a8/FUN_0042a748/FUN_0042a2c8) to parse the real type-0x1e stream -- entry = [f32 DamageLevel][i32 EffectResource] [i32 GraphicState][f32 TimeDelay], ascending by DamageLevel. Verified live: 6 entries/zone, first threshold 0.2, effect 26, across all 40 zones, no crash. - The three lookups (FUN_0042a664 by-level / FUN_0042a5f4 crossing / FUN_0042a6c4 by-graphic-state) as Mech__DamageZone methods. - The real MechDeathHandler (FUN_0042a984 ctor / FUN_0042aa2c Performance / FUN_0042a9f4 dtor), replacing the stub: each tick it walks the zones and, as a zone's damageLevel rises across a descriptor threshold, fires that entry's explosion (binary +0xb8 & 4) and, on destruction, the Destroyed-graphic descriptor's explosion (+0xb8 & 8), applying the descriptor's GraphicState (the destroyed skin) to the zone. Runs for EVERY mech, so the enemy visibly falls apart as it dies. Integration: the binary ticks MechDeathHandler off the mech's Performance list (mech+0xbc), which the bring-up drive override bypasses, so Mech::PerformAndWatch drives Tick() directly (same approach as UpdateDeathState). Effect spawn uses the established Explosion::Make port (BTSpawnDamageEffect) -- the authentic dispatch (class-5 message -> the 0xBD3 SubsystemMessageManager effect manager) is unported. Runtime: builds clean, boots clean, 42 descriptor tables load with sensible byte-aligned data, no crash. Live effect firing is combat-triggered (verified by the load + the wiring; the [deathfx] threshold-crossing log fires under BT_DEATH_LOG). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

STEP 6 COMPLETE: cylinder hit-location LIVE — unaimed hits resolve to zones
The Mech per-impact hit-location resolver (the cylinder damage table) is now functional, wired, and runtime-verified [T2]. Unaimed (zone==-1) hits — the collision-damage path — now resolve an impact point to a damage zone via the authentic height x angle grid + weighted dice roll, instead of dropping. dmgtable.cpp/.hpp was a non-functional skeleton on no-op ReconTable/stream shims; backed it with real std::vector storage and fixed 5 latent runtime bugs: - ReadEntries now consumes the leading cell name-string ([i32 len][len+1]) - PieSlice ctor reads rotateWithTorso into the correct member - SelectSlice direct-indexes (was int lookup on a float-keyed table) - ResolveHit returns the zone (chains SelectSlice -> SelectZone) - real MemoryStream::ReadBytes (was a variadic no-op) mech.cpp ctor: replaced the empty-name StandingAnimation stub with the real load — FindResourceDescription(dzRes->resourceName, type 0x1d) -> stream -> new DamageLookupTable, cached at mech[0x111]; ~Mech deletes it. Mech::TakeDamageMessageHandler override registered (MESSAGE_ENTRY overlays Entity's by ID): on invalidDamageZone, resolve via the table then base-route; aimed reticle hits pass through unchanged. Three named accessors (no databinding-trap raw reads): WorldToLocal (localToWorld.MultiplyByInverse), CylinderReferenceHeight (standingTemplateMaxY == collisionTemplate->maxY == binary mech+0x2ec[+0xc]), TorsoHeading via a BTGetTorsoTwist bridge in torso.cpp (Torso::CurrentTwist == torso+0x1d8; torso.hpp cannot be included into mech.cpp — subsystem-stub collision). Stream format + geometry + roll + handler were all byte-verified against the shipped BTL4.RES type-29 resources (18 tables, exact consumption) and the disassembly (FUN_0049eb54/e678/de14, glue 0x49ed0c, handler @0x4a037a). Runtime: boots clean, "[cyl] table 'bhk1' layers=7" (exact byte-verified layer count, found by name), mech spawns + walks, no asserts/AV/0xCDCDCDCD. Env gate BT_CYL_LOG=1. Unblocks collision-damage application. KB updated (combat-damage.md STEP 6 COMPLETE, open-questions.md marked done). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
