arcattackandClaude Fable 5 fcaea1862a Diag: BT_AF_PERIOD=<sec> autofire cadence throttle + afc_dump.py (raw RES verify)
Closes the coolant/jam investigation. BT_AF_PERIOD pulses the trigger every <sec>s so
a slower-than-max fire rate can be tested; afc_dump.py reads the AFC100 record raw from
BTL4.RES. Both confirm the QA report is FAITHFULLY reproduced (see KB).

arcattackandClaude Fable 5 a83995a755 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. [T1 logic / T2 runtime]

arcattackandClaude Opus 4.8 bfdd41bb9d 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).

arcattackandClaude Opus 4.8 a9c0d2c854 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.

KB: combat-damage.md warns not to route splash through the consolidating msgmgr.

arcattackandClaude Opus 4.8 fa0b825b60 Combat: FIX missile direct damage 6x over-application -- damage once per salvo (task #62)
User live regression: missiles killed a mech in ~2 shots ("takes way more than 2
normally"). Root cause -- DamageZone::TakeDamage (arcade @0041e4e0 == WinTesla
DAMAGE.cpp:379) is `damageLevel += amount*scale` and IGNORES burstCount. So the
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
flying rounds and was damaging on EVERY round = ~missileCount x too lethal on the
direct hit (mirrors the splash over-application fixed in 145a69f).

Fix (mislanch.cpp FireWeapon): only the salvo-LEAD round (i==0) carries damage
(damageData.damageAmount) AND the cluster splash; the other N-1 rounds are VISUAL
(damage 0) -- the tracer ripple, no extra damage. AC unaffected (one round/shot,
not a cluster).

Verified (BT_DMG_LOG [dmghit] trace): per-hit missile damage = clean 5.83, burst
1, once. Missiles-ONLY (BT_AF_MISSILE now independent of BT_AUTOFIRE), single
enemy, 45s: 8 damaging hits, top zone reaches only 0.18, NO death (was death in
~3 pulls) -- "way more than 2" restored. Earlier test deaths were BT_AUTOFIRE
firing laser+PPC+missiles combined, not missiles alone.

KB: combat-damage.md documents burstCount-ignored + the N-round cluster trap
(direct + splash both once-per-salvo).

arcattackandClaude Opus 4.8 145a69f865 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
within SplashRadius) for eyeballing splash; entity-id logging on [enemy]/[splash].
KB: combat-damage.md documents the N-round cluster trap.

arcattackandClaude Opus 4.8 12fbc023a8 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.

arcattackandClaude Fable 5 4c54f7ef0c 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.

arcattackandClaude Fable 5 267059ab88 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).

arcattackandClaude Fable 5 2e9c78d604 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).

arcattackandClaude Fable 5 02cdfd6576 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),

arcattackandClaude Fable 5 065c114590 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).

arcattackandClaude Fable 5 48c9c8444f 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).

arcattackandClaude Fable 5 bb795e2805 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).

arcattackandClaude Fable 5 80cadc98c7 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)

arcattackandClaude Fable 5 d7b900d108 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).

arcattackandClaude Fable 5 092408041c 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.

arcattackandClaude Fable 5 fd055281a8 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].

arcattackandClaude Fable 5 77190c93e5 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).

arcattackandClaude Fable 5 afefaeece5 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).

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.

arcattackandClaude Fable 5 63206d7f19 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.

  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.

arcattackandClaude Fable 5 946323b696 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).

arcattackandClaude Fable 5 cb85517ede 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.

arcattackandClaude Opus 4.8 160b78e38d 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.

arcattackandClaude Opus 4.8 d07dd0bf4e 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.

arcattackandClaude Opus 4.8 247e51e1e1 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.

arcattackandClaude Opus 4.8 83b3f31957 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.

arcattackandClaude Fable 5 e430e474cb 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).

arcattackandClaude Fable 5 29035028fd 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.

arcattackandClaude Fable 5 a110041a70 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.

arcattackandClaude Fable 5 d09cda6c36 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.

arcattackandClaude Fable 5 b6fe686b22 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.

arcattackandClaude Fable 5 d4e139a0d9 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.

arcattackandClaude Fable 5 9353d59eb9 Fix drive-to-range stall: BT_GOTO self-drives + steers correctly cross-net
The BT_GOTO beeline never actually closed on a target -- three separate faults:

1. It was gated behind `if(gBTDrive.forced)`, and `forced` was set ONLY by
   BT_AUTODRIVE -- a chicken-and-egg where the block that would drive was gated
   on the drive already being on.  So BT_GOTO alone just turned in place (the
   "stall").  Fix: BT_GOTO enables forced mode itself AND supplies its own
   forward throttle (a beeline must drive, not only steer), cutting the throttle
   inside a stop radius (weapon range for "enemy", so it holds + shoots).

2. Steering used the gDriveHeading SCALAR MIRROR (seeded to 0), but MP pilots
   spawn facing a non-zero heading -> it steered the WRONG way.  Fix: heading
   error from the mech's ACTUAL forward (localToWorld's -Z axis), signed angle
   to the target.

3. The goto turn was routed through controlsMapper->turnDemand, which zeroes out
   in -net mode (the mapper key-bridge only shapes the local viewpoint mech
   there) -- the heading froze and A drove straight past B.  Fix: apply the goto
   turn to the orientation integration DIRECTLY (if gBTGotoActive, turn=
   gBTGotoTurn), after the mapper read.

Verified 2-node one-box: A with BT_GOTO="enemy" ALONE (no autodrive) drives
dist 1673->231m, holds at weapon range, mechPicks=59, autofire -> B hdlr=192,
DESTROYED -- a fully automated human-style cross-pod KILL via the real beam
path (not the FORCE_DMG hook).  Solo un-regressed (plain autodrive still drives;
goto="enemy" resolves the enemy, mechPicks=59, no crash).  BT_GOTO_LOG traces
the beeline.

arcattackandClaude Fable 5 0dfbb97dcc Fix torso-pitch aim ray: gyro-stabilized boresight from the mech torso
The aim/pick ray was the active RENDER EYE's view direction, which made a
mech unable to aim at a distant enemy:
  (a) it inherited the mech BODY pitch -- on a slope the body tilts ~8 deg to
      conform to terrain, so the boresight pointed that far DOWN and the pick
      ray hit the ground ~50-100m short of the target (groundPicks, never
      mechPicks); and
  (b) in CHASE view (the default) it was the elevated behind-the-shoulder
      camera, so the ray started over the mech's shoulder and flew high.

Fix (L4VIDRND DPLEyeRenderable::Execute, the BTSetAimCamera publish):
- LEVEL the boresight: drop the view-direction pitch and rebuild an upright
  basis (world +Y up) -- the guns fire along the mech's gyro-stabilized
  HORIZONTAL heading, not the terrain-pitched body.  Reticle X still carries
  the torso twist (BTTwistToReticleX); reticle Y any elevation.
- ANCHOR the ray origin at the mech's TORSO (myEntity->localToWorld
  translation + ~5) instead of the render eye, so it is correct in BOTH the
  chase (default) and cockpit views.

Verified end-to-end: solo, enemy 120m ahead, BOTH chase and cockpit view ->
[target] "MECH under boresight ... mechPicks=59 groundPicks=0" -> beam ->
*** DESTROYED.  Also proved PickRayHit resolves a REPLICANT when aimed at it
(hit=1 at 757m, 2-node run).

mech4: BT_GOTO="enemy" test aid now chases the nearest peer of ANY instance
(solo dummy OR replicant), not just replicants.

Still open (locomotion, not aim/MP): BT_GOTO/BT_AUTODRIVE stall short of the
enemy, so an AUTOMATED 2-node kill via the real beam isn't demonstrated yet
(the FORCE_DMG hook still is).  A human can now aim correctly in the default
view.  Solo un-regressed; build clean; KB validator clean.

arcattackandClaude Fable 5 bac45851ad MP task #48 (partial): -net aim+drive already work; localize the real gap
Re-measured interactive -net combat on a 2-node run. The KB's "aim ray dead /
drive dead in -net" was STALE: A's aim ray is live (noRay=0, the active eye
publishes the aim camera) and A drives (BT_AUTODRIVE/BT_GOTO move it). The real
blocker to a human cross-pod kill via the beam path is NOT the netcode:

- Boresight inherits the mech BODY pitch. The aim ray = the active eye's view
  dir; on sloped terrain the body pitches to conform and the boresight points
  ~8 deg down ([EYE] up=(-.03,.99,-.14) == [pick] ldir.y=-0.145 every frame),
  so at range the ray hits terrain ~50-100m short of the enemy (mechPicks=0).
- Drive/goto stalls ~700m short before closing to pick/weapon range.
- PickRayHit vs a replicant is thus unconfirmed, but the replicant localToWorld
  IS correct (lstart magnitude == true A->B distance; the DeadReckon +
  localToWorld=localOrigin block already tracks the replicated position).

Change: add a gated BT_GOTO="enemy" test mode (beeline toward the nearest live
replicant) -- MP spawn coords vary per run so a fixed "x z" can't reliably face
the peer. KB (multiplayer.md) updated with the corrected findings + the real
remaining work (torso-pitch/level-boresight aim ray + drive-to-range).

Solo un-regressed; btl4.exe builds; KB validator clean.

arcattackandClaude Fable 5 54b6663b4d 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.

arcattackandClaude Fable 5 04a2049ce2 MP task #47: DISPROVE the Entity-layout root cause; correct the record
The prior commit (c78662a) filed cross-pod damage failure under a
"cross-TU Entity/EntityID layout divergence" (and the P5 base-region
audit). A compile-time offsetof probe injected into BOTH translation
units disproves that: game/reconstructed AND engine/MUNGA compute an
IDENTICAL Entity layout --

  sizeof(Entity)=444  offsetof(entityID)=380 (0x17C)
  offsetof(ownerID)=388  offsetof(simulationFlags)=32
  offsetof(Mech,entityID)=380  (Entity subobject at 0)

So Entity::Dispatch reads this->entityID at the SAME offset mech4's
GetEntityID() does -- there is no per-TU read difference, and the
logged 3:22 (mech4 candidate) vs 3:19 (engine Dispatch) cannot be one
object read two ways. Those lines were different objects/messages,
mis-correlated. The distinct, REAL P5 "base-region layout divergence"
(HARD_PROBLEMS.md) is about raw-offset stomps at this+0x2d4..0x2f0 --
far above entityID -- and is unrelated to #47.

Changes:
- Revert the committed BT_MP_NET engine diagnostics (ENTITY/EVENT/
  NTTMGR/RECEIVER/L4NET) to the clean a9c3e96 baseline -- those are
  the very instruments that produced the mis-correlated data.
- mech4 BT_MP_FORCE_DMG hook: dispatch via the real m->Dispatch(&td)
  path (no false id stamping); comment records the offsetof finding.
- context/multiplayer.md: layout-divergence RULED OUT; 3:22/3:19 marked
  unconfirmed; leading hypotheses reframed as H2 (wire host-relative
  (de)serialization) vs H3 (replicant id != master's registered key),
  to be distinguished by a 2-node run with per-message correlation.

Solo un-regressed (mech walks + targets, 0 faults). Cross-pod delivery
remains open, but the investigation is redirected off the wrong (large,
structural) layout-audit path onto the EntityID wire/id-assignment path.

arcattackandClaude Fable 5 c78662a0f1 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).

arcattackandClaude Fable 5 a9c3e96f20 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.

arcattackandClaude Fable 5 2250b01c6b Fire-channel pulses moved out of the enemy block (post-kill firing froze)
User report: after killing the enemy, wandering around, weapons won't
fire. Not a lock requirement -- the trigger pulse generator (the
1,0,1,0 edge feed for CheckFireEdge) sat inside `if (gEnemyMech != 0)`.
Once the wreck buried and gEnemyMech nulled, the channels froze at
their last value -> no rising edges -> no fire, even with a valid
terrain pick in the target slot. Latent since the world-pick model made
no-enemy firing meaningful (task #41); the weapon-group split kept the
pulses in the same wrong place.

The pulses now run unconditionally (before the enemy block); the
weapon's own HasActiveTarget gate remains the only fire arbiter --
terrain downrange fires at the scenery, a true sky shot (nothing within
1200) authentically refuses.

Verified: BT_AIM=0.5,0.3 (terrain-only picks, enemy never aimed at) ->
sustained fire, 123 laser + 82 PPC beam samples.

Interim pod-like grouping ahead of the authentic ConfigureMappables/
ChooseButton mapper channels (decomp-anchored in open-questions):
- Three fire channels like three pod buttons: gBTWeaponTrigger (lasers,
  key 1 or SPACE), gBTPPCTrigger (PPCs, key 2), gBTMissileTrigger
  (missiles, key 3 or CTRL). Keyboard only per user (mouse buttons
  removed).
- EmitterSimulation picks its channel by classID (PPC 3028 vs Emitter
  3016); BT_AUTOFIRE holds all three.
- The BT_BEAM_LOG sampler modulus 30 aliased to ONE weapon under the
  new synchronized 5-beam volleys (5 | 30) -> 31 (coprime).

Verified: all 5 energy weapons fire (31 samples each), aimed hits land,
kill completes.

[hud] pip diagnostic logs each registered pip's classID/PipPosition/

"everything is 500m" assumption: BLH lasers red @500 (x3, ext=1),
missiles amber @800 (x2), PPCs blue @900 (x2) -- the pips sit at their
weapons' max-range marks on the range ladder (caret below a pip = that

arcattackandClaude Fable 5 5038d64382 Damage range gate: the authentic per-weapon effectiveRange (was a 100u stand-in)
User report: lock at spawn range (~120) but no damage until closing in.
The bring-up damage gate used kWeaponRange=100 -- a placeholder from
before the weapon reconstruction -- while the authored BLH weapon range
is 500 m. The binary's rule (FireWeapon @004bace8:7758 [T1]): damage
applies when dist <= the weapon's EFFECTIVE range = (1 - host-zone
damage) x authored WeaponRange -- the per-weapon targetWithinRange flag
UpdateTargeting computes each frame. The gate (and the [target] log's
IN WEAPON RANGE annotation) now reads that flag across the weapon
roster; kWeaponRange removed.

Verified: stationary at spawn range 120 -> IN WEAPON RANGE + 34 aimed
zone hits (was 0 until closing under 100).

arcattackandClaude Fable 5 cb110310ba Range caret: the authentic 500 m/s slide (HudSimulation :5652-5670)
The right-ladder caret reads range-to-pick, and with the world-pick
model the pick is usually the ground downrange -- so walking (cockpit
bob + turning sweeping the boresight across near/far terrain) made the
caret teleport frame to frame ("going all over the place", user
report). The binary rate-limits the DISPLAYED range: shown +=
clamp(true - shown, +-dt*500) -- a 500 m/s slide, applied in
HudSimulation, including toward the no-target 1200 default
(_DAT_004b7ed0 confirmed 0 = the abs() idiom). Implemented in mech4's
HUD feed where dt is in scope.

arcattackandClaude Fable 5 305c928923 Death effects dispatch at the victim's death transition (task #42)
User report: enemy takes hits, starts smoking, then beams pass through
-- no more damage, no death. Root cause: the death-effects dispatch
(blhdead explosion chain + wreck swap + KILL score) lived in the
SHOOTER's laser fire block kill check. A missile killing blow lands
frames later in BTUpdateProjectiles -- outside that block -- and after
task #41 the boresight pick skips a dead mech, so the fire block never
ran against it again: the death chain was silently skipped, leaving an
internally-dead, smoking, standing, invulnerable mech.

Fix: the dispatch moved to the VICTIM's own once-per-death transition
(UpdateDeathState's movementMode->9 moment) -- fires exactly once for
ANY kill source (laser, missile, collision). Killer id for the
Explosion message = lastInflictingID (the task-#31 bookkeeping). The
BT_ENABLE_TEARDOWN cdb harness was removed with the old block (findings
preserved in docs/HARD_PROBLEMS.md).

Verified headless (75s soak, missile-heavy kill): destroyed ->
'blhdead' id=22 -> wreck swap 'blhdbr.bgf' -> smoke re-arm -> sink ->
buried INERT; post-death picks fall through to terrain; 0 crashes.
