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.

Diag: BT_TRNRATE probe -- turn-in-place body-rate vs trn-clip cadence (task #50)
Confirmed via BT_TRNRATE + direct disasm of the un-exported perf drive (0x4aa3d3) that turn-in-place rate == walkingTurnRate (speed=0 collapses the lerp) and the trn clip cadence is authentically FIXED -- so the reconstruction is faithful and the residual legs-vs-body slip is authentic (decoupled by design; scaling the clip would deviate from the decomp). Probe left env-gated for future asset-tuning checks. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

MP: FIX peer spin hang/divergence -- exact quaternion integration + frequent orientation (task #50)
Answers 'how did the original handle this?' from the decomp (subagent hunt):
the 1995 binary's replicant reckoner (FUN_004ab1c8 -> FUN_00409f58, part_000.c:9359)
integrates heading EXACTLY: build a unit axis-angle rotation quaternion from
angularVelocity*dt ({axis*sin(t/2), cos(t/2)}) and Hamilton-multiply it onto the
heading (FUN_00409d9c) -- exact for any timestep, stays on the unit sphere. It
further carries the full orientation quaternion in the FREQUENT pose record
(FUN_0040a938, 7-float pose), so the dead-reckon gap stays tiny.
Our reconstruction diverged two ways, both fixed:
1. ReconQuatIntegrate (mechrecon.hpp) -- the reconstruction of FUN_00409f58 -- was
STUBBED as , a crude small-angle VECTOR add. Restored to
the real exact axis-angle composition. (A 'no stand-ins' violation: the comment
even wrongly claimed Quaternion::Add == FUN_00409f58.)
2. The engine Mover reckoner (MOVER.cpp AcceleratedDeadReckoner/LinearDeadReckoner)
also did the vector Add on projectedOrigin.angularPosition -> over a long peer
record gap it diverged to ~180deg then snapped (the reported spin HANG/hesitation).
Routed both through a new ExactAngularProject() helper (same exact math).
3. Orientation only rode the sparse type-4 resync; during a PURE spin the linear
dense-send never fires (not translating), so the gap ballooned (~1.6s) and the now-
exact projection sat far ahead -> the slerp jumped. Added an ANGULAR dense-send
(resync every frame while |yawRate|>0.1), mirroring the original's frequent-
orientation model -> gap stays tiny -> smooth.
Verified live-autonomous (BT_AUTODRIVE+BT_FORCE_TURN + BT_RENDHDG render-rate probe):
the ~180deg divergence + multi-radian snaps are GONE (rendered maxStep 0.05-0.10 rad,
no jumps). User confirms: no frame hang/hesitation. MOVER.cpp change is strictly
more correct (exact==crude for the small per-frame master case; only large-gap peer
extrapolation changes), so walking is unaffected.
KNOWN REMAINING (separate, smaller): the turn-STEP leg animation (trn clip, mech2.cpp
advance_normally) runs at a FIXED idleStrideScale cadence that does not scale with the
rotation rate, so the legs lag/skip vs the (now-correct) body rotation. Next.

Diag: render-rate rotation-evenness probe + angular-drift instrumentation (task #50 spin residual)
Autonomous headless spin harness (BT_AUTODRIVE+BT_FORCE_TURN) + probes that finally measure what the eye sees, not the sim heading: - BT_RENDHDG (L4VIDEO render loop): per-RENDERED-frame peer heading step evenness -- avgStep/maxStep/max-avg ratio. Confirmed the residual spin 'hesitation' is UNEVEN rendered rotation (max/avg ~2.8x), correlated with the byAngle resync-flood bursts (maxAng ~= pi), NOT a render-vs-sim rate stall (render redraws a fresh heading every frame). - BT_SPIN / BT_ANGSIGN: resync trigger breakdown (byAngle/byVel/byRest) + the frame-level local/update/projected angular-Y that exposed the Abs() macro bug. - gBTReplRenderYaw: peer heading published from the sim to the render probe. - Normalize projectedOrigin.angularPosition after the peer-mirror advance (adding a scaled ang-vel VECTOR to a quaternion denormalizes it) -- correct, but NOT sufficient: the pi divergence is REAL, from the crude large-angle quaternion projection over the sparse angular-record interval during a PURE spin (linear dense-send doesn't fire when not translating; type-4 is the only orientation carrier and resets the horizon, so dense type-4 -> half-rate). Residual ROOT (scoped, not yet fixed): the reckoner (MOVER.cpp:457-466) projects rotation by ADDING vector*t to the heading quaternion -- a small-angle approx the original kept valid via dense records; our pure-spin case has 1.6s record gaps so it diverges to ~180deg -> uneven render. Fix path = proper quaternion integration in the reckoner, or refresh the angular origin without the type-4 horizon reset. Both touch the shared engine dead-reckon -> aligning before the change.

MP: FIX peer spin freeze/half-rate -- unparenthesized Abs() macro floods angular resync (task #50)
Root cause found via autonomous headless spin (BT_AUTODRIVE+BT_FORCE_TURN) +
frame-level [angsign] probe: the STYLE.H:118 macro
#define Abs(value) ((value>0) ? value : -value)
has NO parens around value, so Abs(a-b) mis-expands to (a-b>0 ? a-b : -a-b) ==
-(a+b) on the false branch, NOT |a-b|. The angular resync velocity gate passed
an EXPRESSION: Abs(localVelocity.angular.y - updateVelocity.angular.y). For a
steady spin the two are equal, so a-b==0 takes the false branch and yields
-(2*rate): on a REVERSE spin that is +2*rate > velDb, firing a type-4 resync
EVERY frame. The resync flood reset the peer's dead-reckon horizon every frame,
pinning its angular slerp at ~half rate and (as the drift periodically ran to
180deg) freezing the rotation for seconds while the leg turn-clip kept stomping.
Confirmed live-autonomous: velDrift 0 (was +2.618), byVel 0 (was 55/55), peer
rendered-rotation median dyaw/expected 1.00 (was 0.49), no multi-second dt gaps.
Fix (mech4.cpp resync gate, reconstruction side -- the engine macro is original,
the original master-perf avoided it by diffing into a temp):
- velDrift: diff into a temp, explicit (d<0?-d:d) so the macro never sees an
expression.
- angDrift: already reworked to a single-variable wrap-safe yaw delta (also
dodges the macro) -- and it corrects a prior units/wrap bug (was comparing a
raw quaternion-Y component against a radian deadband).
- velocity gate now diffs vs updateVelocity (the value the peer extrapolates
with), same scalar representation as localVelocity.
- BT_SPIN / BT_ANGSIGN / updYaw diagnostic probes (env-gated).
KNOWN RESIDUAL (smaller, follow-up): the ANGLE gate still bursts when the crude
large-angle quaternion projection in the reckoner runs updateOrigin stale between
writes and drifts ~180deg; causes occasional single-frame hitches (peer median is
still 1.0), not the freeze. Separate from this fix.

MP: FIX peer gait jitter -- feed the leg channel the REPLICATED commanded speed (task #50)
Decomp-verified via multi-agent investigation (workflow wv1km7lvc, adversarially
checked against reference/decomp/all/part_012.c + engine T0).
ROOT CAUSE (D3 CONFIRMED): the peer's leg channel FUN_004a5028 reads its speed
demand from mapper->speedDemand (**(mech+0x128)+0x128, part_012.c:11947/11975/
12028). The reconstruction FABRICATED that input from the noisy dead-reckoned
velocity magnitude and PINNED it flat with a standSpeed*1.05 floor across the
walk threshold -- the leg stutter/skip + cadence-vs-travel desync, worst on
accel/decel. The authentic input is the replicated commanded speed
bodyTargetSpeed@0x6b4 -- the master's own throttle-commanded speedDemand
(mechmppr.cpp:749), stamped into every record (mech.cpp:2036) and read back on
the peer (mech.cpp:1833/1841/1871). It is the IDENTICAL value the master's leg
channel consumes, so the peer clears the stand->walk gate exactly when the master
does and ramps cadence continuously through accel/decel.
Confirms the 07-13/07-14 regression:

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: FIX replicant walk-entry floor -- gate on standSpeed not walkStrideLength (task #50)
The prior floor gated on walkStrideLength*0.5, but walkStrideLength is a stride METRIC (~22.0), not the walk velocity (~6.1) -- so the condition sd > 11 was never true for a walking peer and the floor never fired. The replicant's derived speedDemand (== actual velocity 6.13) sits BELOW standSpeed (6.83), so the leg SM's stand->walk gate (standSpeed < demand) never tripped and the peer slid forward in the Standing pose. Gate on standSpeed instead: floor the demand to standSpeed*1.05 when the peer is clearly walking (demand in (standSpeed*0.5, standSpeed*1.05)). Verified live: uvel=6.13 -> spd=7.169 floored, legState enters 5 (walk) on frame 1 with no Standing-pose slide. standSpeed=6.8277 confirmed.

MP: FIX replicant 'slides before it steps' -- walk-entry floor on derived demand
Root-caused from a live per-frame [replmov] trace (user's session, where replication works -- the headless rig won't spawn a replicant): the replicant's leg SM sat in Standing (legState 0, legFrm pinned at 19) while dead-reckoning forward at spd=6.13, until the master's speed rose to 6.99, then it snapped to StandToWalk. Cause: the replicant derives speedDemand from the master's ACTUAL velocity, but a mech's forward walk velocity == walkStrideLength, which sits BELOW standSpeed (bhk1: walk 6.13 < stand ~6.8). The leg SM's stand->walk gate is , so a steadily-walking peer's derived demand NEVER crosses it -> the peer slides in the standing pose until the master happens to accelerate past standSpeed. The master never hits this: it feeds the leg SM its COMMANDED throttle speed (>> standSpeed), not the actual velocity. Fix: when the peer is clearly moving forward, floor the derived demand just past standSpeed so it enters the walk cycle immediately; the walk case clamps legCycleSpeed back to walkStrideLength, so cadence still matches travel (no foot-slip). Reverse needs no floor (its gate is commandedSpeed < ZeroSpeed, tripped by any negative). Diag: BT_REPL_MOV (per-frame replicant pos/vel/speed/legState/legFrm + master twin).

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).

Gait: FIX replicant trn regression -- gate master-perf turn-stop exit to masters
Today's authentic trn dispatcher folded the master-perf turn-STOP exit into leg/body case 4. But the master perf (FUN_004a9b5c) runs on MasterInstance mechs, NOT replicants -- and a replicant derives turnDemand from the noisy REPLICATED yaw rate (mech4.cpp:1968), which dips into the +-0.05 deadband between dead-reckon updates. So the exit kicked the peer out of trn every few frames -> the peer 'rotated as a statue' + jerky (user-reported regression from yesterday). Gate both turn-stop exits to GetInstance() != ReplicantInstance; the replicant advances the trn clip from its replicated turn signal exactly as before the exit was added. Also BT_REPL_TRN probe (mech4.cpp) logs the replicant yawRate/turnDemand/legState. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Fix BT_SPAWN_AT terrain embed + add BT_COOL_LOG probe
BT_SPAWN_AT teleport set only X/Z, keeping the old (dropzone) Y -- so teleporting to a new spot embedded the mech in sloped terrain (user-reported). Lift the teleport +500 above the old elevation so the authentic per-frame ground SNAP (BoxTree FindBoundingBoxUnder, no gravity) settles it onto the surface next frame (the snap only lowers, so it must start above the surface). Diagnostic only. Also BT_COOL_LOG (heat.cpp): logs a heat subsystem's damageLevel/heatLoad/coolantDraw when it carries damage -- for the 'do damaged mechs leak coolant' investigation.

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.

Gait: turn-then-walk stutter ROOT-CAUSED + FIXED -- one skeleton writer (task #64)
User repro (100%): turn in place, push forward before the turn stops -> the gait
skips/stutters + visibly reduced bob; standstill starts always clean. Three-layer
fix, user-verified:
1) THE DISPLAY BUG (the actual visible artifact): v5's "body advances first with
mj=1, leg overwrites last, so body drift can't show" was FALSE. Whenever the two
gait channels phase-split, the BODY channel's out-of-phase joint writes leaked
into the rendered skeleton (rhythmic leg skips, averaged-down bob) while every
leg-channel trace read clean -- the leg DATA was fine, the RENDERED pose wasn't
the leg's. v6: AdvanceBodyAnimation(dt, mj=0) -- the body still advances +
projects for replication (records/cycle speeds unchanged) but no longer touches
the skeleton. One writer, structurally; matches the binary's own observable
("body phase drift is locally INVISIBLE in the binary"). BT_BODY_MJ=1 = old A/B.
2) THE SPLIT SEED: the bring-up trn trigger armed only the LEG channel, so a
turn-in-place entry guaranteed the channels re-entered walk frames apart and the
walk cycles ran permanently out of phase. Lockstep: the Standing trn entry arms
BOTH channels the same frame (body case-4 twin added, same rate/keying), gated on
both Standing. The authentic dispatcher (un-decompiled master-perf gap 0x4a9b5c-
0x4ab188, the sole reader of turnDemand/turnCapable) armed both -- the body's
case-4 machinery is dead code otherwise [T1].
3) THE POSE-MATCH INVARIANT: the engine has NO pose blending; transitions avoid
pops purely by authored pose-matched boundaries. The old trn exits cut the pivot
clip MID-STEP (legFrm 7->1 teleport). Now: entry gated on near-zero speed
(turn-IN-place); on forward command the pivot FAST-FORWARDS to completion (x4)
and the authentic finish callback lands Standing at the stand pose -> the normal
pose-matched stand->walk runs. Decompiled reverse abort kept; the standSpeed
mid-clip abort subsumed (it WAS the pose cut). [T3: 0.25*standSpeed threshold +
4x rate stand in for the gap's constants.]
Harness: BT_FORCE_TURN now reaches gBTDrive.turn (was silently inert for the
gait), BT_WALK_DELAY=<s> holds forced throttle then ramps (the turn-first repro),
BT_GAIT_TRACE=1 per-frame gait trace. Regressions: standstill start, turn-entry,
pure pivot loops, run cycle -- all clean, bob full amplitude (1.33/1.32).

Combat: FIX splash mis-routed onto the direct victim via the msgmgr (task #62)
User: struck a mech ~4x, still standing -- but the [dmghit] trace showed the DIRECT victim taking 16 applications for 8 impacts while the intended splash bystander took 0. Root cause: BTApplySplashDamage delivered splash through the shooter's SubsystemMessageManager::AddDamageMessage, which CONSOLIDATES every damage message of a frame onto the FIRST hit entity (commonDamageInformation. entityHit, messmgr.cpp:279). The direct hit registered the primary as the common entity, so the bystander's splash was consolidated onto the primary too -- the excluded direct victim took 8 direct + 8 mis-routed splash = 2x, and the real bystander took nothing. Fix: deliver splash with a DIRECT e->Dispatch to each victim, matching the T0 source (EXPLODE.cpp:246 target_entity->Dispatch); Dispatch reroutes cross-pod for a replicant on its own. Verified (BT_DMG_LOG): 8 impacts -> 8 dmghit on the direct victim + 8 on the bystander (was 16/0); no death; per-hit 5.83.

arcade's ONE cluster Missile per trigger lands its damageAmount EXACTLY ONCE; the
missileCount/burstCount split is cosmetic for zone damage (only gyro-bounce +
splash-falloff read burstCount). The port re-expresses that one cluster as N

Combat: FIX missile splash over-application -- once per salvo, not per round (task #62)
Live regression: a clustered bystander died in ~2 missile salvos ("suddenly
lethal"). Root cause, not authentic: the arcade fires ONE cluster Missile per
trigger (burstCount=missileCount) doing ONE SplashDamage event with baseBurst =
missileCount, floored at 1 ONCE. The port re-expresses that cluster as N flying
BTProjectile rounds, and task #62 fired splash PER ROUND -- each baseBurst=1,
each floored at 1 -- so the distance floor was applied N times = ~missileCount x
too much splash.
Fix: BTProjectile.splashBurst tags ONLY the salvo-lead round. MissileLauncher::
FireWeapon passes nmiss (the cluster count) on i==0 and 0 on every other round;
the contact + world-impact splash hooks fire only when splashBurst>0, using it as
baseBurst. One splash event per salvo with baseBurst=missileCount -- matches the
single arcade cluster missile. Replicant mirror rounds carry 0 (damage 0 too) so
the master's cross-pod splash isn't doubled. AC unaffected (not a MissileLauncher;
splash_burst defaults 0).
Verified headless (BT_SPAWN_ENEMY=2 clustered rig, 45s): bystander now takes 6
splash events (1/salvo, baseBurst=6) and SURVIVES (was ~2 shots); primary dies to
direct hits in ~3 trigger pulls (36 missiles == single-enemy TTK); AC does not
splash; no crash. Also: BT_SPAWN_ENEMY read as a COUNT (=2 clusters a bystander

Combat: MISSILE SPLASH DAMAGE -- Explosion::SplashDamage reconstructed (task #62)
Area-of-effect blast on missile detonation, from the T0 source EXPLODE.cpp:50-254 (@0042fad0) + the arcade decomp. Fires on ANY missile impact (world or mech) -- the +0x360 gate sits in the Missile::Perform collision branch (part_013.c:10097). Only missiles splash; the AC's tracer is not a Missile. Radius source CORRECTED: it is the ROUND's own GameModel (type-0xf) +0x50, seeded from the launcher's linked AmmoBin ammoModelFile @0x1e8 (part_013.c:8778) -- NOT the launcher's ExplosionModelFile (which resolved to 0). Live-resolved radius = 30 for both MP missile launchers; 0 for AC/Emitters. Burst falloff = baseBurst / dist^exp floored at 1 (arcade 1.25 = decomp 0x3ff40000; WinTesla EXPLODE.cpp:209 drifted to 1.2f). damageType/amount pass through unchanged; only burstCount, radial damageForce, and impactPoint are set. Excludes shooter + direct victim; dist>radius gated; delivered via msgmgr (cross-pod) or Dispatch. New: BTResolveSplashRadius / BTApplySplashDamage (mech4.cpp), hooked at both the world-impact and contact detonation paths; BTAmmoRoundModelResource bridge (ammobin). Env: BT_SPLASH_LOG, BT_SPLASH_TEST (synthetic near-miss), BT_AF_MISSILE (missile autofire). Verified: near-miss dist=15 -> 1 burst to a bystander; live missiles detonate + exclude the direct victim; AC does not splash; no crash. Deferred (T3): per-player enable sub-gate missile+0x360 = BTPlayer+0x264 (writers read as a per-frame toggle, not a config flag) -- port treats SplashRadius>0 as the enable. KB: combat-damage.md + open-questions.md updated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

Ballistic FX: DAFC muzzle flash + autocannon fire replication (task #61)
The autocannon gains its authentic muzzle effect AND becomes visible when an enemy fires it -- the ballistic-FX gap behind "I only see the AC from my own view." MUZZLE FLASH (the genuine shipped effect, not the cut card): - MUZFLASH.BGF is an orphaned/cut asset (nothing references it) -- so it is NOT rendered. The shipped projectile-gun muzzle effect is DAFC.PFX, which BTDPL.INI documents as "the effect used on all projectile guns" (psfx 6 external / 14 internal): an orange fire-smoke blast (btfx:firesmoke1), maxIssue 25 over ~0.2s so the emitter auto-expires = one burst per shot. - BTFlashMuzzle (mech4.cpp) spawns it on the gun-port SEGMENT via the existing BTStartPfxAttached path; the segment frame sprays -Z out the barrel. Hooked at ProjectileWeapon::FireWeapon (the fire edge). Default ON (BT_MUZZLE=0 disables). AC only -- lasers show their beam, missiles their launch. ENEMY AC FIRE NOW REPLICATES (the real find): - ROOT CAUSE: the subsystem-record replication channel EXISTS and works (mech ticks subsystem->PerformAndWatch(update_stream); Entity::UpdateMessageHandler routes incoming records to GetSimulation(subsystemID-1)->ReadUpdateRecord). The emitter (beam) and MissileLauncher (salvo mirror) both call ForceUpdate() so their fire serializes -> enemy lasers + missiles ARE visible on the peer. The AUTOCANNON set only `simulationFlags |= 0x1` (the +0x28 instance flag, NOT the updateModel bit WriteSimulationUpdate walks) and had NO fire record, so its shot never crossed the wire -- the enemy's cannon was invisible. - FIX (the AC twin of the missile salvo mirror): ProjectileWeapon:: WriteUpdateRecord/ReadUpdateRecord (fire counter + aim) + ForceUpdate() in FireWeapon. The replicant edge-detects the counter and mirrors ONE visual round + DAFC muzzle flash from its own resolved muzzle; a null/untargeted aim streaks straight out the barrel (launchVelocity) instead of toward origin. - Verified live 2-node: the watching node logs REPLICANT AC shots + DAFC flashes at the enemy's gun-port (seg 7), aimed shots fly to the real target; no crashes. TRACER: all ACs author TracerInterval=1 (every round is a tracer); the existing amber streak is acceptable-authentic, so no tracer change was needed. KB: open-questions.md -- CORRECTED the (wrong) earlier note that claimed no subsystem-record channel exists; it does, the AC just wasn't using it. Logged the methodology lesson: the coverage audit finds UNWRITTEN functions, not "reconstructed but inert" ones (a function present but never called -- the AC record + the missile mirror both looked done); a LIVENESS audit would catch that class.

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.
VERIFIED live (BT_HIP_LOG probe): your walking mech writes jointhip=0 (level);
the peer's replica in the other pod's view leans at exactly -8.0/-11.1deg --
the authored clip values. A/B control: L4VIEWEXT=1 forces the walking master
back to 74 sustained -8/-11 writes.
KB: locomotion.md ("NO walk lean" audit conclusion CORRECTED -- the lean is
authored + sustained + clip-set-specific), asset-formats.md (.ANI parses
pitch/yaw/roll for all joint types; KeyJointPos translation; cycle clips carry
no pitch), open-questions.md (item closed).

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).

Fire VISUALS wave: the authored firesmoke sheet, vertex-alpha effect cards, the case-4 wreck dressing
The "fireballs like the demo vids" arc, decomp/content-grounded end to end,
plus the live-play UX batch verified over the same sessions:
FIRESMOKE SHEET (the PFX fireball fix): every firesmokeN_scr_tex in BTFX.VMF
maps the SAME 64x64 tileable noise image bintA (variants differ only in SCROLL
rate) and firesmoke1_mtl colours it through the "fiery" ramp (0.3,0.1,0.1)->
(0.9,0.7,0.3). The particle layer now bakes ramp(lum(bintA)) as its sprite
colour (noise detail in alpha) and SCROLLS it at firesmoke1's authored rate
via a texture-transform; the port's radial soft-edge mask moved to a second
CLAMPed stage so the WRAPPED scroll rolls flame through the sprite without
scrolling the edge away. Old grit x radial bake kept as the no-BINTA fallback.
Impact hits, damage-band smoke and death booms all ride this layer.
AUTHORED TEXTURE SCROLL in the model path: the BMF TEXTURE records carry
SPECIAL " SCROLL u0 v0 du dv" (tag 0x2037); the draw path always supported
per-op scrolling (SetTextureScrolling) but the BGF loader never parsed it, so
every scrolling material rendered frozen. Wired TexRef -> MatInfo -> batch ->
L4TEXOP.doScroll: the flame cards (flamebig/fire5) now roll fire noise.
VERTEX-ALPHA EFFECT CARDS (the "twisted drill bit of fire" fix): FLAMEBIG's
verts carry authored float RGBA -- white-hot base (1.0,0.99,0.97) -> dark-red
tip fading to alpha -0.2 (the DPL clamp convention). The loader kept a flat
batch colour and drew it OPAQUE = a solid orange spike. Corpus sweep: exactly
14 shipped BGFs carry vertex alpha, ALL effect cards (flames, MUZFLASH,
EXDISK_A/B/C, TMST_A/B/C, beam models, DECLOUDS). Such batches now keep the
authored per-vertex gradient and route to the alpha-blend pass, unlit,
colour = texture x gradient, alpha = the vertex fade; sky objects excluded
(drawAsSky + alphaTest passes NEITHER pass filter -- DECLOUDS stays in the
sky pass). MUZFLASH/EXDISK render correctly for free when the muzzle-model
work lands.
WRECK DRESSING (the 1996 ExplosionScripts case-4 transcription): pieces spawn
HIDDEN and reveal 0.25s after the boom (the InstanceSwitch delay, behind the
dnboom flash); flamebig hangs over the pile, Y-BILLBOARDED at the camera
(SetOffsetYaw + a camera-pos getter -- the dpl_SetDCSReorientAxes analog);
the MakeDCSFall settle arms at the reveal with the two authored rates (hulk/
debris -0.025 t^2, fires -0.01 t^2 -- the flames ride above the sinking pile
and die with it at burial). EMPTY-PLACEHOLDER hulk guard: THRDBR.BGF is a
153-byte zero-geometry stub that "loads fine" -- vertex-count check now routes
it to the gendbr fallback (a Thor wreck was invisible). Hulk content census
recorded: AVADBR==MADDBR==VULDBR geometry (palette-only prefix diffs),
RAPDBR==SNDDBR==STIDBR byte-identical -- wreck variety is materials + the
dressing, not unique piles.
LIVE-PLAY BATCH: muzzle resolve uses the named segmentIndex (raw +0xdc read
was layout garbage); forward launch frame (authored MuzzleVelocity +Z vs the
mech's -Z facing); dock-bottom single window (gauge strip appended below the
world viewport, 1100x600 default, BT_DEV_GAUGES_WINDOW=1 restores the separate
window); portrait sec surface unrotated CW; ammo counters live via typed
bridges (BTAmmoBinCountPtr/BTAmmoBinFeeding/BTWeaponAmmoBin -- raw bin+0x180
and a hand-rolled link walk were garbage); fourth fire key ('4' = Pinky);
panel/arc probes de-aliased (%61 prime).
KB: rendering.md (vertex-alpha card family + scroll), combat-damage.md (hulk
census + THRDBR stub), gauges-hud.md (ammo bridges).

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).

Cockpit: the COOLANT VALVE control -- the heat-management triad completes (task #13)
The pilot's third heat tool: Condenser::MoveValve (id 4, the Condenser handler table @0x50E52C -- PE-verified, exactly one entry) registered via the order-proof function-local accessor and GUARDED by the real FUN_004ac9c8 (task #12's BTPlayerRoleLocksAdvanced rookie-role bridge -- the old deferral note blamed the 0xBD3 messmgr, a stale misattribution, swept). Each press cycles the valve 1 -> 5 -> 50 -> 0 -> 1 and RecomputeCondenserValves re-shares the fixed total coolant flow across all six condensers -- opening one valve wide starves the others: the pilot's cooling-triage lever. Desktop: 'C' cycles the selected condenser's valve (BT_VALVE_SLOT picks the roster slot; default Condenser1). BT_VALVE_TEST scripts a headless press. Verified live: press -> "[valve] condenser#1 valveState=5 flow=0.5 (total=10)" -- exactly the authored redistribution math (5/(5+5x1)), through the real role gate. The heat-management triad is now complete and all-authentic: G + fire buttons = regroup weapons across buttons (task #6) F5-F8 / F9 = reassign weapon generators / mode (task #12) C = coolant valve triage (task #13) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Cockpit: GENERATOR POWER ROUTING -- assign weapons to generators (task #12)
The pilot's second heat-management tool: the PoweredSubsystem message table
@0x50F4EC (ids 4-8) registered and implemented -- SelectGeneratorA-D
(@004b099c..@004b0a74: FindGeneratorByNumber roster walk on generatorNumber
@0x1E0 -> AttachToVoltageSource re-tap with tap accounting -> modeAlarm
Connected) and ToggleGeneratorMode (@004b0abc: Manual -> Auto -> detach+Manual
cycle). Weapons inherit via the MechWeapon handler chain. Desktop: F5-F8
assign the selected weapon (BT_CONFIG_SLOT) to Generator A-D, F9 toggles
reconnect mode; BT_GENSEL_TEST scripts a headless verify.
Verified live end-to-end: dispatch -> handler -> re-tap ("PPC_1 ->
GeneratorD (tapped)") -> the charging I^2R physically moved (GenD cold ~90K
baseline -> ~1570K carrying the PPC; GenA relieved), stable over a sustained
autofire soak with thermal-breaker trips.
FOUR defects found and fixed on the way [all T1/T2]:
- THE e17 HEAT EXPLOSION: Generator::SourceLevel misread *(this[0x38]+0x158)
as linkedSinks->heatEnergy; it is the engine-base DamageZone @0xE0 ->
damageLevel [0..1] (the same named-member pattern as the bank radiator's
zone read). A breaker-restarting generator emitted (1 - 4e8) x 10000
volts; squared through the customers' I^2R feed, one restart blew the
whole thermal network to e17. Authentic: a damaged generator yields
proportionally less voltage.
- FUN_004ac9c8 is NOT "IsDamaged": raw body = owner -> mech+0x190 player ->
roleClassIndex(+0x274) == 0 -- the ROOKIE-role lockout for advanced
cockpit systems. New bridge BTPlayerRoleLocksAdvanced (NULL player =
unlocked [T3]; bring-up role 2 = unlocked). The old stand-in gated the
handlers off permanently (healthy subsystems have simulationState==1).
- MESSAGE_ENTRY tables must be FUNCTION-LOCAL statics inside the accessor:
as namespace-scope arrays they are read by other TUs' static-init chains
before their own initializers run -- Build copies zeros and every id in
the table is silently dropped (ids 9/10 only worked by TU-order luck;
both tables relocated; gotcha recorded, reconstruction-gotchas #9).
- The AutoConnect hunt scanned GetSegment() -- the raw @004b0bd0 walks the
subsystem ROSTER (+0x124/+0x128); EntitySegments were being cast to
Subsystems (the classic +0x128 gotcha).
Also: the dense handler table's GAP slots (skipped ids) are uninitialized
heap -- the name-based Find strcmp-walks them and AVs; diagnostic probes use
the id-based Find only (the 1995 binary's own tables carry the same holes).

Cockpit: the CONFIG-MODE weapon-regrouping session + the live-play fire fixes (tasks #6+#11)
TASK #6 -- the pod's in-cockpit weapon regrouping, fully reconstructed and live-verified (hold-configure -> tap fire button -> toggle membership -> release-commit): - MechWeapon handlers id 9 ConfigureMappables @004b9550 / id 10 ChooseButton @004b95b8 (binary table @0x511860; the old "Myomers fns" mislabel swept) + the GetMessageHandlers() accessor chain through Emitter/ProjectileWeapon/ MissileLauncher/GAUSS/PPC (empty per-class sets swallowed dispatch). - Mapper vtable truth: +0x38 EnterConfiguration / +0x3C ExitConfiguration / +0x40,+0x44 AddOrErase evt/dir. No "secondary vtable @0050f498", no "CreateTemporaryEventMappings" virtual (RP-name drift; swept incl CLASSMAP). L4 Enter/Exit rebuilt complete: StartMappableButtonsConfigure (the NonMapping 0x10000 <-> Mapping 0x8000 mode flip + the gauge's active-weapon latch) + the held-button re-arm + the 4 fire-button temp maps; only the RIO mapper implements the toggle (Thrustmaster no-ops = can't regroup). - MechSubsystem +0xE8/+0xEC corrected to controlDestination/controlMessageID (ex hostEntity/subsystemId2 mislabel); MechWeapon ctor defaults the destination to &fireImpulse (@004b99a8). - ConfigMapGauge state loop reconstructed (PE-recovered DAT_00518eb4 table; buttonGroup GetMapState sampler -- the "needs ModeManager" guard rationale was wrong). Finding [T1]: the shipped binary NEVER enables this gauge (no SetColor caller) -- authentically dormant; BT_CONFIGMAP=1 is the dev enable. - Dev harness: HOLD 'G' opens the session (BT_CONFIG_SLOT picks the weapon); BT_CONFIG_TEST scripts a headless verify. @004afbc4 corrected to its real Fail-trap body (the guessed AddOrErase(NULL) body would corrupt groups). - Bonus [T1]: the binary MechWeapon ATTRIBUTE table has ELEVEN entries (PercentDone..WeaponState) -- "TriggerState is the only one" was wrong. TASK #11 -- the user-reported live-play regressions (both real bugs): - PHANTOM FIRE: the mech4 bring-up shot block painted an explosion at the victim on its OWN 0.3s cadence whenever fire was held -- desynced once the authentic recharges landed. Retired (the real impact visual flows from each discharge via the messmgr SubmitExplosion). - WEAPON BRICKING (the "cuts out" bug): the Loading->Loaded snap window (+-0.01 around seekV) assumes the pod's LOCKED 60 fps; one port dt-spike jumps it, the byte-verified >1.0 clamp (_DAT_004ba830=0) zeroes readiness, and the weapon sticks in Loading at level ~10000 forever (observed live). Fixed with pod-frame (1/60s) sub-stepping of the binary's own Loading tick -- also fixes the I^2R integral over-heating generators on big steps. NEW GOTCHA CLASS recorded: reconstruction-gotchas #12 (frame-pacing trap). - Duty-cycle measured (max-rate autofire): generators equilibrate in the degradation band (recharge stretch ~3.5-4.4x), the FailureHeat breaker never trips solo, PPCs sustain ~11.8-damage full-charge fire. The slow kill pacing and recharge gaps are the AUTHENTIC heat economy; the pilot's counters (this regrouping UI, generator reassignment, coolant valves) are the reconstruction queue.

Combat: THE AUTHENTIC DAMAGE ECONOMY -- authored per-weapon amounts through the real fire chain (task #8)
Three root causes, all fixed: 1. kDamageScale was 1.0 -- _DAT_004bafbc is an x87 float80 = 1e-7, cancelling the ctor's x1e7: damagePortion = authored DamageAmount x (charge/seekV)^2 (closed form at fire time; madcat AC=25/LRM=50/ERLL=6, bhk1 PPC=12/SRM=35). The observed "0.25" was the degenerate EC=1 fallback, never authored data. 2. CheckFireEdge NaN latch: TriggerState carries ControlsButton INTS; the release value (-65) is a negative NaN. The binary's x87 unordered compare read it as "released"; IEEE-correct float compares latched the edge detector shut after the first release -- the reason the emitter discharge chain NEVER fired in-game. Fixed with bit-pattern sign compares. 3. The weapon-side submission LIVE: Emitter::FireWeapon fills damageData (amount + damageForce=target-muzzle [the gyro directional-bounce feed] + impact) -> MechWeapon::SendDamageMessage (@004b9728 real body) -> messmgr consolidation with per-weapon records + explosion bundling. The mech4 bring-up damage block + flat kShotDamage retired to diag hooks. Bonus: LODReuseHysteresis 0.82 -> 0.33 (double misread). Zone model verified byte-exact (no change). Solo end-to-end: 5-record volleys (2 PPC + 3 ERML with authored amounts), per-weapon zone granularity, explosions, kill. Heat stays bring-up scale pending the heat-calibration audit [T3].

Combat: the AUTHENTIC consolidated damage delivery -- TakeDamageStream through the message manager (task #7 tail)
ConsolidateAndSendDamage @0049b784 fully implemented: the beam path submits
into AddDamageMessage; each messmgr tick builds ONE Entity::
TakeDamageStreamMessage (id 0x13; wire-verified 0x34+4+Nx12) with the
common impact record + appended {type, amount, subsystemID} entries and
Dispatches it at the victim -- the T0 handler (ENTITY.cpp:817) re-splits
into per-record TakeDamage; replicants reroute cross-pod. Real
ResolveExplosionID (firing weapon's +0x3E4, guarded) + SubmitExplosion via
the Explosion::Make port; TWO chain-purge bugs fixed (the "iterator dtor
clears it" assumption was wrong -- records re-applied every tick, observed
1->2->3->4 double-counting). @004b9728 identity corrected (SendDamageMessage,
not DrawWeaponPip). Verified solo: 25 clean single-record consolidations ->
kill -> death transition. Residue: weapon-side submission awaits the
damage-economy reconciliation (authored 0.25-scale vs kShotDamage=12).

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> |

Combat: AUTHENTIC weapon groups -- streamed per-mech button bindings + the real fire chain (task #5)
The recovered system: fire channels = LBE4ControlsManager buttonGroups (0x40/0x45/0x46/0x47); default groups = the per-mech type-6 controls-map resource in BTL4.RES, installed by the T0 CreateStreamedMappings the port already called -- it needed only the TriggerState attribute (id 0x13 PINNED to the binary value; fireImpulse@0x31C is the binary's TriggerState) and an input feed. Keyboard/harness now push press/release edges into the button groups; the gBT*Trigger bypasses, per-type keyboard split and 1,0 pulse hack are retired -- weapons sharing a button fire TOGETHER (madcat Trigger = 4 weapons). Myomers @4b9550/@4b95b8 misattribution corrected (they are MechWeapon ConfigureMappables/ChooseButton). Verified 2-node: kill through the authentic chain (12 hits vs ~36 pre-groups). Config-mode session (regrouping UI) = the remaining stage, KB-scoped. 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> |

The binding was in the zone ctor all along: Ghidra dropped the two arg pushes @0049d0e1 (Slot::AddImplementation(subsystemArray[streamedIndex])), making it read as a bare Resolve(). DZSlot stand-in -> engine SlotOf<T>; SendSubsystemDamage rewritten to the recovered @0049c9a8 body (allotment into the subsystem's OWN private zone; vital -> graphicAlarm 9); CriticalHit -> real ApplyDamageAndMeasure; parentArtifactZone.Add revived (LOD damage averaging); videoObjectFlag renamed vitalSubsystem (+0xE4). BT_CRIT_PROBE diag added. Verified: 66 plugs bound/mech; probe-destroyed zone -> crits damaged/DESTROYED, statusAlarm + destroyed-skin chain fire; MP kill + solo un-regressed.

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).

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.

Respawn: swirl warp, cockpit-not-black on respawn, observer sees peer un-wreck
Three respawn-visual bugs the user saw, each grounded in the engine/decomp:
1. Warp = flat blue BLOB, not the demo's swirly blue/light-blue/white shimmer.
Ground truth (content/VIDEO/MAT/DAY/BTFX.VMF): tsphere_mtl = a SCROLLING bintA
texture (tsphere_scr_tex, SPECIAL SCROLL) + EMISSIVE {0.7,0.5,1} + RAMP "sky"
(dark-blue->white). The swirl IS the scrolling texture; the colour is the
emissive/ramp. Our draw did COLOROP=SELECTARG1/ARG1=TFACTOR, which REPLACES
every texel with one flat colour -> the blob. Fix: MODULATE the (bound,
scrolling) texture by a TFACTOR set to the authentic EMISSIVE hue (0xB380FF)
so the swirl survives and reads blue-white. DrawMesh's cached SetTexture
(L4D3D.cpp:1215) leaves our MODULATE ops standing since textured meshes drew
first. Additive glow, all state saved/restored.
2. First-person view BLACK on the dying/respawning mech until V. SetViewInside's
body-hide + '_cop' canopy suppression + viewSkeleton update were gated !wrecked,
and RebuildMechRenderables (respawn un-wreck) restored the full OUTSIDE torso
with no '_cop' rule -> the cockpit eyepoint ended up wrapped in opaque geometry.
Fix: factor the per-segment mesh selection into ApplyViewSkeleton(viewpoint,
inside) shared by SetViewInside AND RebuildMechRenderables, so respawn re-asserts
the inside skeleton + '_cop' hide; record viewSkeleton even while wrecked. Only
the mech the local camera views FROM gets the inside treatment (a replicant is
always outside).
3. OBSERVER never saw the peer respawn -- the peer's wreck sat forever. The wreck
appears incidentally via rising damage-zone replication -> MechDeathHandler::Tick
-> BTRemakeMechModel (one-way). The un-wreck+warp ran master-only in Mech::Reset.
Fix (reuses the existing damage channel, no stream-framing change): Mech::Reset
also ForceUpdate(DamageZoneUpdateModelFlag) so healed zones cross; Tick handles
the FALLING edge -- on a ReplicantInstance whose zone heals from destroyed, call
BTRebuildMechModel + BTStartWarpEffect once (wasWrecked latch). This is the port
analog of the binary's type-0 graphic-state -> ResetPose un-wreck hook
(Mech::ReadUpdateRecord case 0); the full Mech::WriteUpdateRecord death record
(type 6) is deferred (would touch the netcode framing).
Smoke-verified headless (2-node): victim respawns intact + warp; observer logs
"replicant un-wrecked + warp" at the peer's spawn point; no crash.

Respawn visuals: warp was in the wrong render pass; render never un-wrecked
Two render bugs behind "warp never appears" + "respawned mech stays a sunk wreck": 1. Warp invisible: the tsphere was drawn in PASS_ALPHABLEND, but DrawMesh skips any op whose alphaTest != (pass==PASS_ALPHABLEND) (L4D3D.cpp:1045) and tsphere's op is opaque -> every op skipped, nothing drawn. Flag the sphere's ops for the alpha pass, and draw it as an explicit translucent-blue ADDITIVE glow (state saved+restored) so it reads as a warp shimmer, not an opaque ball or (as shipped) nothing. Tint via BT_WARP_COLOR. 2. Render stays wrecked on respawn: SwapToWreck hides the body + hangs a sinking dbr hulk with render_tree.wrecked a one-way latch; Mech::Reset healed the sim but nothing reversed the render, so the reborn mech kept rendering as the sunk hulk. Add RebuildMechRenderables (the heal direction of RemakeEntity): drop the hulk/debris, clear wrecked, restore every body segment to its now-intact mesh. Mech::Reset calls it via BTRebuildMechModel. Smoke-verified: tsphere loads with its op alpha-flagged; on each respawn "[BTrender] respawn: rebuilt intact model (12 segs restored, hulk dropped)"; no crash. Both are local render (the respawning node's own screen); remote-observer replication of the warp+un-wreck rides the deferred WriteUpdateRecord death path.

Reset-based respawn: reuse+heal the mech, not create-a-new-one (task #52)
The respawn glitches (2 mechs, on-fire respawn, camera-inside, can't-control, wreck-never-disappears) all traced to one architectural divergence: our respawn SEVERED playerVehicle on death and CREATED a new mech, leaving the old as a permanent wreck and building a duplicate viewpoint whose old render tree was never torn down. The authentic engine (FUN_0049fb74 + RPPlayer) REUSES the same mech entity: on respawn Mech::Reset heals it and moves it in place. Implemented faithfully, adapted to our layout (the 1995 raw offsets map to different 2007 engine fields, so reset the equivalent named members, not the offsets): - Mech::Reset (real, was a reposition-only stub): reposition + kill dead-reckon (projectedOrigin/projectedVelocity/updateVelocity + our relocated gait accumulators) so the replicant stops lerping to the death spot; clear the death latch (movementMode=1, graphicAlarm=0); Heal every damage zone (new Mech__DamageZone::Heal: full structure, intact skin); DeathReset (vtable+0x28) every subsystem; ForceUpdate to broadcast. - btplayer.cpp: VehicleDead no longer severs playerVehicle; the respawn re-post gates on the mech still being dead; DropZoneReply resets the EXISTING mech in place (heal+move) instead of creating a new one, then fires the warp. Warp moved to the shared placement (initial drop-in + respawn). Verified 2-node: mech entity ID stays 3:22 across 3 deaths (reused, not a new 3:32); each Reset logs alive=1, 20 zones healed, 33 subsystems reset; A sees ONE mech (no wreck+new pair). Warp fires each respawn. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

Whirlwind respawn: authentic death->drop-zone->recreate cycle (task #52)
Death transition (mech4) now dispatches VehicleDead(-1) to the owning player; BTPlayer::VehicleDeadMessageHandler restructured to the authentic @004c05c4 three-way branch: -1 = death bookkeeping + sever playerVehicle (wreck stays) + 5s re-post; >=0 = engine drop-zone hunt -> DropZoneReply -> CreatePlayerVehicle (new mech); -2 = the acquire probe. Guarded on a DropZones group so a zone-less mission stays dead instead of aborting. Three latent bugs the respawn path exposed, all fixed: - IsMechDestroyed latched on graphicAlarm>=9 alone; a later leg hit on the wreck rewrites the alarm to 4/3, un-latching -> the death transition re-ran (double kill/score, abort). Now latches on movementMode 2||9. - Score handlers dereferenced the severed playerVehicle during the dead window; guarded. - The console score flush routed a NetworkClient::Message through the player's Entity::Dispatch, which stamps entityID past the smaller struct -> /RTC1 stack overflow. Sent via application->SendMessage instead. - Renderer LoadMission re-entry (per viewpoint-make) re-read the env INI; its light block Fail'd on stale sceneLightCount. Reset it in DPLReadEnvironment so the respawn's second read is clean. Verified 2-node self-drive: B killed repeatedly by A respawns each time (wreck stays), ticks + reloads + takes fresh damage on the new mech, no abort/hang across multiple death->respawn cycles.

Death gate: a destroyed mech takes no pilot input (ghost-drive fix)
User report from 2-window play: after dying, the pilot could still steer the wreck around invisibly. Zero throttle/turn/fire and the forced harnesses at the gBTDrive source when IsMechDestroyed() -- deliberately INPUT-only, so the gait/animation machinery keeps running and the death collapse plays out. Also recorded in the KB: the killer's screen shows the wreck SWAP but not the death SINK (needs the Mech-level death/knockdown update records, disasm preserved from task #51), and the respawn-cycle scouting (type-12 intro scripts are binary ref-records; adrop; DropZone + Mech::Reset machinery) for the recovery-whirlwind reconstruction (task #52).

Cross-pod beams: replicate emitter discharge via subsystem update records
User report: lasers only visible on the window firing them. The peer's replicant emitters never learned the master fired. THE AUTHENTIC PIPE (decomp-verified): - FUN_0041c350 (the "beam keepalive" ServiceDischarge/ContinueDischarge call) does TWO things: queue the LOCAL deferred beam-effect callback (@0x4bac0c) on the app+0x34 manager -- our per-weapon render walk already plays that role -- and set the subsystem DIRTY bit, which maps to the 2007 engine's updateModel / ForceUpdate(). - Replication rides SUBSYSTEM UPDATE RECORDS inside the mech's update message: the roster walk already hands the entity's stream to every subsystem's PerformAndWatch; Simulation::WriteSimulationUpdate serializes each requested updateModel bit; Entity::UpdateMessageHandler routes received records by subsystemID to the subsystem's ReadUpdateRecord. All engine machinery -- the missing pieces were the Emitter's serialize/apply pair + the triggers. CORRECTIONS to the dormant task-33-era transcriptions (never exercised -- nothing ever set updateModel -- so the latent misreads never surfaced): - The weapon-family VTABLE SLOT MAP was swapped: slot 6 = ReadUpdateRecord, 7 = WriteUpdateRecord, 9 = TakeDamage (evidence: Mech hierarchy symmetry + body semantics; @004ba568 resolves an EntityID at rec+0x30 through the entity index -- record semantics, not Damage). Renamed across MechWeapon / Emitter / ProjectileWeapon; the real Emitter::TakeDamage @004bafc8 is undecoded (inherits MechWeapon for now). - Emitter/MechWeapon Write: `*record = 0x38/0x18` is the record LENGTH, not recordID; rec+0x30 is the TARGET's EntityID (GetEntityID()), not a colour -- the old `CopyColor(targetEntity+0x184)` was also a databinding trap. - OVERRIDE-SIGNATURE TRAP: the decls used each class's own shadowing UpdateRecord typedef as the param type, silently NOT overriding the engine virtual (the base ran instead; nothing would ever have serialized). Base-typed params (Simulation__UpdateRecord*), casts inside. - Emitter::ReadUpdateRecord reconstructed (@004ba568): target EntityID resolve (drop unknown non-null targets), MechWeapon alarm apply chain, beam fields. - ServiceDischarge/ContinueDischarge: ForceUpdate() per keepalive tick + one final record at beam end (turns the peer's beam off). - Mech::DrawWeaponBeams extracted from the player-only drive block so the walk runs for REPLICANTS (+ per-mech gun-port cache -- the process-wide statics would have served the player's segment pointers as the replicant's muzzles). VERIFIED 2-node: A fires 57 volleys -> 225 emitter records -> B applies all 225 -> B draws 414 beams (PPC blue / laser red, from A's replicant's own gun ports). Solo un-regressed (150 beams, kill chain, no crash). Also preserved: the full Mech::WriteUpdateRecord @0x4a0c2c recovery (reference/decomp/mech_writeupdate_004a0c2c.disasm.txt) with all 9 record types decoded (pose/alarm/leg-state+heat with the body-channel write-through re-sync, knockdown, death, impact, movementMode) -- transcription deferred; it replicates remote knockdown/death/heat and was not needed for beams.

Fix "can't turn in MP": pilotArray[1] overrun stomped controlMode
User report from the first live 2-window session: throttle worked, A/D turn
did nothing. [mppr] showed the input REACHING the mapper (stickX=-1) but
turnDemand=0 and controlMode = pointer garbage (73583232 / 217478632 --
different per instance), from frame 1, MP only (solo mode=0).
Hunted with a cdb hardware write-breakpoint (ba w4 armed at ctor time on
&controlMode, compiled offset +0x128 from the [mode-ctor] probe). Caught the
writers red-handed: MechControlsMapper::BuildPilotArray / FillPilotArray.
ROOT CAUSE -- a shrunk-span array: the binary reserves a FIXED 10-slot pilot
block @0x15C..0x183 ((pilotArrayBuilt@0x184 - 0x15C)/4 = 10); the recon
declared `Pilot *pilotArray[1]` ("variable length"), so every write past
slot 0 stomps the members declared after it. In MP, FillPilotArray wrote the
PEER's Player pointer into slot 1 = over controlMode -> the turn shaping
dispatched on pointer garbage -> turnDemand 0. MASKED in solo: the zero-loop
overrun wrote 0 there, and 0 == BasicMode. This was ALSO the real cause of
task #48's "turnDemand zeroes out in -net" observation (worked around then
with the direct goto-turn; attribution corrected in the KB).
Fix: pilotArray sized to the binary's own 10-slot span; ctor zeroes all
slots; BuildPilotArray clamps pilotCount to capacity (local + 9 remotes; an
8-pod game fits). Diagnostics kept (BT_MODE_LOG ctor probe; [mppr] line now
prints mapper/&mode).
VERIFIED: MP session holds mode=0 throughout, turnDemand flows nonzero, the
mech turns (heading -1.33) and closes on the peer; solo kill chain intact.
KB: new "shrunk-span array" gotcha (reconstruction-gotchas 5) with the cdb
ba-w4 recipe; multiplayer.md task-#48 note corrected.

MP: replicant gait animation -- peer mechs walk instead of sliding (task #50)
A peer's replicant mech slid around as a frozen statue: DeadReckon moved localOrigin but nothing animated the legs. Reconstruct the replicated-motion display loop: after DeadReckon, derive a SIGNED speed demand from the replicated velocity (the master publishes worldLinearVelocity in every update record, Mover::WriteUpdateRecord MOVER.cpp:759; the replicant stores it in updateVelocity.linearMotion :712; sign = forward dot against the -Z facing), write it to controlsMapper->speedDemand (the LEG channel's live demand source), and advance the LEG state machine for its JOINT writes only -- travel stays with DeadReckon, so position always follows the master and the clip cadence matches the replicated speed. Two replicant-only initialization holes found live (the master's equivalents are primed per-frame in the PLAYER-only drive block): - globalTimeScale/idleStrideScale read 0 -> clip advance time dt*0, the leg machine engaged (state 11) but the clip froze (legCycle stuck 0); - reverseSpeedMax2 (the run-cycle rise-clamp @0x7a0; LoadLocomotionClips does NOT set it) read debug-heap garbage -> legCycleSpeed clamped to -4.3e8 on entering run state 13. Primed both; legCycleSpeed sane-banded once. VERIFIED 2-node (BT_GOTO driver + BT_REPL_LOG observer): the replicant runs the full gait lifecycle -- stand -> walk(5,7) -> run(10,12), legCycle 7.5->34 tracking the master's speed, wind-down(8), Standing(0) when the master stops. Solo un-regressed (goto->aim->kill chain intact, no crash). projectedVelocity source-swap (the binary publishes the BODY channel's smoothed projection instead of the actual travel velocity) evaluated and DEFERRED: it risks a verified working replication feed for a smoothing nuance; recorded in multiplayer.md.

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.

Gait v5: display+travel from the LEG channel (kills the stutter class)
User-reported recurrence of "legs stutter and lose sync". Live [sync] showed
advSum/legSum drifting 5->92 during walk-up churn, then locking. Reproduced
headlessly (BT_FORCE_OSC throttle feathering + BT_FORCE_TURN + the new
per-frame BT_SYNC_LOG probe) and root-caused in two parts:
- SEED: the bring-up turn-in-place trigger arms only the LEG channel, so the
walk re-entry lands one frame apart -> a persistent clip phase offset.
- AMPLIFIER: with offset clips the two end-of-clip callbacks fire on different
frames; a demand change landing between them picks DIFFERENT next states
(one channel winds down, the other keeps walking) -> opposite-phase churn
(observed bs=6 ls=7 -- body on walk-R, leg on walk-L).
Under v4 (display+travel = BODY) the out-of-phase LEG pose showed through on
every frame the body didn't write joints (Standing/wind-down) = the visible
stutter/pop.
DISASM GROUND TRUTH (neither Advance fn has a static decomp caller; found by
byte-scanning the CODE section for e8 calls):
- master perf (0x4a9b5c gap) -> AdvanceLegAnimation @0x4aa399 (air @0x4aa388)
-> -dist/dt into localVelocity (+0x1cc): the LEG drives LOCAL travel and
(writing last) the displayed pose;
- IntegrateMotion (0x4ab1c8, body advance @0x4ab312, caller FUN_004ab430 =
the projected-origin updater) -> -dist/dt into projectedVelocity (+0x2a0):
the BODY is the dead-reckoning PROJECTOR -- locally invisible.
v4's reading of FUN_004ab430 as the travel source was wrong.
FIX: advance body FIRST (projection; its writes get overwritten), leg LAST
(displayed pose); travel = legAdv under the two-channel split. Display ==
travel through the LEG by construction -- body-channel drift can no longer
become visible, structurally (not by input-symmetry luck).
Verified: trn+feathering repro clean; straight drive locked (adv==proj);
solo goto=enemy kill chain intact; MP 2-node drive-to-range cross-pod kill
intact (241 hits, DESTROYED); no crashes. KB corrected (locomotion.md roles
+ P3_LOCOMOTION.md v5 entry). New gated instruments: BT_SYNC_LOG,
BT_FORCE_OSC.
