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).

Gauges: the CLOSEOUT wave -- radar pips, Myomers dedup, attribute parity, ledger sweep (tasks #14-#17)
TASK #17 -- AUTHENTIC RADAR SYMBOLOGY (the cross-blip stand-in retired). The recon proved the 'missing pip raster set' never existed as BT game code: pips are the ENGINE's L4GaugeImage vector-stroke system (T0 source in tree, L4GAUIMA.cpp == FUN_0046f0c0 line-for-line), the 'pip table' is L4Warehouse:: gaugeImageBin keyed by Entity::resourceID, and BTL4.RES ships 110 type-0x12 shapes (every mech/vehicle/building/tree). The six btl4rdr stubs are wired to the real facilities: contacts draw their authentic model silhouettes with LOD selection, the target gets the binary's 4px-inflated box highlight, and player-name labels resolve via Mission::GetSmallNameBitmap (the prebuilt 64x16 egg rasters keyed by the player's bitmapindex). DECODED: the invented 'VideoObject' was Entity::owningPlayer all along (+0x190; nameID = playerBitmapIndex@0x1E0, target = BTPlayer::objectiveMech@0x284 -- new bridge BTPlayerObjectiveMechOf); the 'LabelledEntity' class is Landmark (cultural.h; label path dormant -- no landmark content ships, no runtime landmarkID writer). The L4GREND BT_DEV_GAUGES warehouse guard is removed (its AV had a different culprit, below); resource type 18 corrected to GaugeImageStream in decomp-reference (was mislabeled 'ModelList'). TASK #14 -- the Myomers ODR duplicate ELIMINATED: the powersub.cpp/hpp 'Myomers' (classID 0xBC3 -- actually Sensor) is retired whole; it duplicated ?DefaultData@Myomers@@ against the real class (dumpbin-verified) and /FORCE picked the winner by link order. The real Myomers (0xBC6) now chains PoweredSubsystem's handler set (ids 4-8) and publishes its SEVEN binary attributes (@00511588: SpeedEffect/Current/Recommended/Min/MaxSeekVoltage- Index/SeekVoltage/OutputVoltage) -- the old empty unchained index starved the Myomer engineering panel of every resolve. TASK #16 -- attribute parity: MechWeapon publishes the FULL binary table @0x511890 (11 entries; ids renumbered to binary truth -- the port aliases had squatted the binary's DistanceToTarget/TargetWithinRange ids; the streamed TriggerState 0x13 binding unchanged). Binary names resolved two TODO members: pipState -> estimatedReadyTime (attr 0x1A), and the EXT-model flag is the binary's RearFiring (0x1B). ThermalSight LightState published. HUD (offset conflicts) + missile-side tables (id encoding suspect) documented for a re-dump instead of publishing blind. THE CRASH THIS EXPOSED [T2, cdb-verified]: gotcha #11's dense-table gap is a LATENT AV, not a guaranteed one -- the old table's 0x0D..0x12 gap (task #5) survived on heap luck; the renumber reshuffled allocations and Find() AV'd on a garbage entryName in WeaponCluster's PercentDone resolve. Fixed with five named PAD entries (the mech.cpp attrPad idiom) + a static_assert locking the pad base to PoweredSubsystem::NextAttributeID. Gotcha #11 amended with the proof. TASK #15 -- stale-ledger sweep: GAUGE_COMPOSITE ('composite not yet built', Reservoir shadow, PlayerStatus/vehicleSubSystems 'remaining', valve-dormant- until-0xBD3, sensor guard, the superseded 'Heat MFD near-static' reframe -- all banner-corrected), gauges-hud frontmatter, L4VB16 + powersub comments. Verified live: 50/50 config attribute bindings resolve, 0 NULLs, 0 parse skips, mech spawns and simulates 31/31 subsystems, no cross-blip fallbacks, the pip cache fills through entity registration without the old guard.

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.

Heat: THE AUTHENTIC ELECTRICAL MODEL -- weapons recharge from generators (task #10)
Task #10 set out to fix "scrambled linked-sink routing"; a [heat-link] attach log proved the routing was NEVER scrambled (every subsystem links its authored condenser exactly; the "pools in Condenser1" read was the diagnostic-sampler aliasing trap). The real defect: emitter.cpp's local FUN_00417ab4 stub returned NULL, so the whole electrical model was inert and the E7 force-charge recharged every emitter in ONE frame (~0.3s cycle, 1501 fires/90s, ~1.7e9 heat/s -- the "runaway"). Landed authentically [T1: disasm + byte-verified constants]: - Emitter ctor @004bb120: seekVoltage = authored fraction x generator ratedVoltage (10000); EC = energyTotal/(seekV^2 x 0.5); voltageScale@0x310 = (RechargeRate / -ln(1 - 1e-4 x seekV)) / EC -- charge reaches seekV[rec] in EXACTLY the authored RechargeRate (PPC 5s, ERL 4s, SRM 3s, ERM 2s) cold. Owner-flags ctor gate (the usual gotcha; the this-flags read never armed). - PoweredSubsystem::ChargeTimeScale (@004b0d50, was a =1.0 stub): voltageScale x (1 + thermalResistivity x srcTempRise) -- hot generators charge slower. ("voltageScale is never read back" was wrong; corrected + swept.) - TrackSeekVoltage @004ba838: charging I^2R -> the GENERATOR's pendingHeat (~3.5e8/full PPC charge) -- generators self-heat, conduct to their authored condensers, and throttle further charging. The feedback economy closes. - FailureHeat consumers found: this+0x184 == 2 gates BOTH weapon families (@004baa88 emitter: reset firing + hold charge 0; @004bbd36 ballistic: recoil=rechargeRate + alarm 7). Emitter::GetFaultState un-stubbed. - ProjectileWeaponSimulation @004bbd04 opens with call 0x4b0bd0 (disasm) -- launchers now run the powered/heat step (their firing heat previously accumulated in pendingHeat forever). - heat.cpp: per-instance BT_HEAT_LOG census (the old shared-static 1-Hz sampler aliased); [heat-link] attach log; the stolen-else Verify restored. Verified live (120s max-rate autofire): PPC ~470-500 (was 55,000), bank plateaus ~600 and sheds to ambient, generators 1100-1400, ERMLaser self-regulates at the authored 2000 failure threshold (shutdown-cool-resume).

Heat: authentic 1e7-unit heat + the ambient radiator land (task #9)
- Emitters: heatPortion closed form = heatCostToFire x 1e7 x (charge/seekV)^2 (PPC 1.1e8 -> +632K on its own sink); the missing projectile/missile heat adds (raw -- resources author pre-scaled 1e7 units). - The bank's AMBIENT RADIATOR @4ae73c reconstructed (the system's ONLY heat exit; conductance x 0.1 x HeatSinkCount -- _DAT_004ae974 float80 = 0.1) + the link-attach guard corrected (skip = the 0xBBE bank, not Condenser; the inversion blocked condenser->bank links and closed the system). - Constant corrections (all byte-verified float80s): coolant epsilons 0.0025/0.003/1e-4 (was a single 1e-4 serving three sites); CoolantCapacityScale 0.05 (was 1.738). - Verified: heat flows + exits; max-rate autofire overheats weapons into the authentic heatLoad range-cutout (thermal spam unsustainable by design). - KNOWN REMAINING: linked-sink routing scrambled (heat pools in Condenser1; authored map says PPC->C4/C6) -- the heat-stream offset audit, filed.

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).

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).

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.

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.

View: the INI viewangle is the HORIZONTAL field -- authentic 60x47 frustum (task #55)
Community reports said the camera looked too far back and the cockpit frames were never this revealed; the user's hypothesis (our projection widens the view) was exactly right. The original Tesla projection call, preserved in a comment at DPLRenderer::SetView, is dpl_SetViewProjection(view, -1, -aspect, +1, +aspect, 1/tan(viewangle/2)) i.e. BTDPL.INI's viewangle=60.0 is the HORIZONTAL field of view with the vertical derived by aspect: the pod's frustum was 60 x 46.8 deg at 4:3. The port fed the 60 to D3DXMatrixPerspectiveFovRH as the VERTICAL fov -> 75 x 60 at 4:3 (worse on widescreen): the world rendered ~25% farther away and far more canopy was visible than the pod ever showed. Fix: BTFovYFromHorizontal(viewangle, aspect) at all five projection sites (main, per-frame resize, sky pass, WM_SIZE rebuild, fallback) -- the horizontal field stays the authentic 60 deg at any window shape. The aim boresight reads the live projection (gBTAimP22) and adapts; combat re-verified (kill chain, no NaN). Cockpits now show the frames at the pod's framing: viewports dominant, frames at the periphery. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Cockpit: the authentic punch STENCIL-CUT -- all 8 cockpits real (task #55)
The user caught the inversion (blocked viewports, see-through frames); the
answer came from the rasterizer board itself: an i860 disassembly of the
VREND.MNG firmware decoded the damageize handler (@0xf040f6f8) -- cmd 0x20
(vr_damage_action) writes the dpl_Punchize token triple onto the punch
geogroup's first three geometry chunks IN FILE ORDER:
chunk1 = the detailed window-aperture shapes -> an invisible per-pixel MASK
chunk2 = the coarse hull -> the ONLY colour-drawn geometry (where not masked)
chunk3 = byte-identical hull twin -> the damage-reset record, never visible
Visible canopy = hull-minus-apertures. Both earlier readings were wrong ways
around the same three chunks: dropping all punch left floating fragments (no
hull); hiding the duplicate pair hid the HULL and drew the MASK -- the exact
inversion observed.
Port: bgfload tags per punch patch {non-paired pmesh = mask (role 1),
first twin = hull (role 2), second twin = skip}; L4D3D DrawMesh runs
mask->stencil-1 (no colour/z-write, z-tested), hull->stencil-NOTEQUAL,
mask->stencil-0; device D24X8 -> D24S8 + stencil clear. The cut never
touches z, so later-drawn entities show through the apertures.
BT_COP_PLATES=1 disables (diag).
In-game, all 8 mechs on pure defaults: connected dark frames with clear
viewports -- thor (the footage mech) shows the central viewport + surrounding
frame exactly as filmed. Combat regression clean (kill + no NaN).
Arena textured punch uses the same firmware kit; the black-texel alpha path
there is a working approximation, flagged in the KB.

Cockpit: punch patches ARE the windows -- all 8 mechs authentic (task #55)
Resolved the non-Madcat blocked views. Rendering every *_COP shell offline from its mech's AUTHORED eye (SKL [jointeye] translation -- incl. the Thor's +1.13 offset cockpit) with faces coloured by punch flag showed the answer plainly: the PUNCH-tagged patches sit exactly over the window apertures in all 8 mechs. On these texture-less black-diffuse shells dpl_Punchize renders the tagged geogroup as holes -- the punch patches are the transparent WINDSHIELDS, and the visible frame is only the non-punch geometry. The loader now drops the punch batches of _cop meshes (bgfload finish(); BT_COP_KEEPPUNCH=1 keeps them for diagnosis). In-game sweep on pure defaults: - madcat: the dark dome frame (matches gameplay footage) - thor / owens / sunder: authentic brace/dash/pillar remnants - bhk1 / loki / vulture / avatar: authentically FRAMELESS (all-punch canopies -- the pod showed no frame for those mechs) (An early-session test that "disproved" drop-punch ran with the broken pre-inverse eye; its conclusion was wrong and is corrected in the KB.)

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)

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.

Cockpit: authentic eyepoint + canopy lattice render (task #55)
The first-person cockpit now shows by default and matches gameplay footage (verified on the Madcat). Two decomp-verified reconstructions: EYEPOINT (FUN_004579a8 + caller part_014.c:5525, FUN_004c22c4): - eye offset = siteeyepoint GetBaseOffset (not GetSegmentToEntity, not the upright hack), parented on the PARENT segment DCS (btl4vid.cpp) - live view = affine INVERSE of the eye world matrix (L4VIDRND Execute) -- replaces the hand-rolled LookAtRH whose +Z-forward/+Y-up row guess aimed some mechs into the canopy; combine order fixed to baseOffset * R - chase camera basis + aim boresight re-expressed for the inverse convention (row2 = back); boresight now derives from the view matrix (the stale rows aimed the pick ray at the sky = no target, no discharge) CANOPY (*_COP.BGF, dpl_Punchize geogroups): - every shell is an open strut lattice (38-59% boundary edges, all 12 mechs); rendered single-sided with per-face INWARD winding (l/r torso patches are mirrored, so no global winding works) the struts are the dark frame and the openings show the world - frame colour = the 'softer' ramp near its dark end (texture-less unlit ramp; BLXSKIN.BMF has no texture -- the old "punch texels" theory was wrong) - scoped by filename (meshIsCop); wrong drop-punch + view-cut paths removed - BT_FORCE_MODEL=<name> forces the player mech for per-mech bring-up KB: new context/cockpit-view.md topic; punch split corrected in bgf-format; gotchas 14 (LookAt axis guess) + 15 (per-patch edge namespaces); env gates + eye/punch addresses in decomp-reference.

Diag: add BT_SHOT backbuffer dump + correct/park the -net render glitch (task #53)
Scouted the "-net node render glitch". Two prior framings were wrong and are corrected in the KB: it is NOT device contention (retracted earlier), and it is NOT a from-load glitch -- the trigger is a RESPAWN (user correction). It's a post-respawn render-rebuild fault on the MP path. Could not reproduce in 9 automated 2-node loads + a forced death/respawn (all clean). Debug uninit is a deterministic 0xCDCDCDCD, so the intermittency implies a race -- and the task #52 respawn fixes (LoadMission re-entry, viewpoint relink, death-latch) plausibly already closed it. Parked as WATCH; re-open if it recurs. Tooling (general, off by default): BT_SHOT=<path> dumps a per-instance backbuffer PNG from the world-render path (L4VIDEO.cpp) every 90 frames -- lets us capture a specific node's frame without foregrounding the window. Used with scratchpad/hunt53.sh (N-run divergence hunter) to verify a fix if the glitch returns. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

Warp: restore the translocation-vortex look + fix texture-scroll precision collapse (task #52)
The death/respawn "blue whirlwind" (tsphere) now matches the original cabinet
photo (capture.png): a smooth spinning lavender vortex with a bright core.
Root cause of the long-standing "radial spokes" artifact was NOT the warp code
but a general engine bug: L4D3D::SetTextureScrolling computed its texture-matrix
offset as scrollDelta * absolute_time, which grows unbounded and collapses UV
float precision -> a smooth scrolled cloud shatters into grainy radial steps.
Wrapped with fmodf(..., 1.0f) (identical under REPEAT tiling, full precision).
This also cleans the scrolling bexp beam grit and any other SCROLL material.
Visual reconstruction (verified against the real 45-vtx TSPHERE.BGF bicone,
offline-rasterized then ported):
- view ON-AXIS (eye centred on the throat) + spin in place -> concentric rings
(decomp FUN_00453dc4 does spin-about-local-Z + submit; the port had stubbed it)
- bintA cloud through a WIDE lavender ramp at full contrast (drawn as SKY);
no geometry "bands", no log-polar twist, no off-axis tornado (all discarded)
- tessellate the 12-facet bicone smooth; isotropic + trilinear; ramp baked into
the texture and drawn SELECTARG1(TEXTURE) to avoid double-tinting
Env knobs (BT_WARP_*) default to the verified values; BT_WARP_SELFTEST/SELFSHOT
are an off-by-default visual-verification harness (backbuffer frame dump).
Docs: new context/translocation-warp.md (geometry/material/visual/lifecycle/env);
reconstruction-gotchas.md gains the accumulated-time precision-collapse bug class;
rendering.md / multiplayer.md / decomp-reference.md / CLAUDE.md cross-linked.

Implement the translocation sphere -- the "blue warp" respawn effect (task #52)
BTTranslocationRenderable was a no-op stub; now reconstructed over the engine's POVTranslocateRenderable: loads tsphere.bgf and runs a collapse-on-arrival / expand-on-reveal sphere (scale 100->1 over 1.3s, then 1->150 over 1.0s, rotating) keyed on the player's SimulationState dial. Drawn direct from the render loop by BTDrawTranslocationSpheres (beside BTDrawBeams, PASS_ALPHABLEND) -- the same accommodation the beams/reticle use. The asset loads by FILENAME (tsphere.bgf), not through the RES table -- which is why every resource-name search missed the effect for three rounds. Trigger wiring: btl4vid.cpp MakeEntityRenderables builds the sphere for the LOCAL player (the authentic wiring builds it only for replicants + a POV fade for self, but peer player-attribute replication isn't wired -- on a replicant SimulationState/ DropZoneLocation read uninitialised). btplayer.cpp pulses SimulationState DropZoneAcquired->VehicleTranslocated at respawn (a 1.4s flip timer stands in for the engine's +1s drop-zone re-post) and writes the respawn origin into the DropZoneLocation attribute. Verified 2-node (BT_TLOC_LOG): on respawn the sphere collapses (~100->5) then expands (->150) at the valid drop-zone origin, deduped to <=2 active, respawn cycle un-regressed, no render errors. Visual appearance (colour/size) still needs a live look; the authentic see-others'-spheres path needs player replication. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

KB CORRECTION: the blue whirlwind IS in the game — the translocation sphere (tsphere.bgf)
My earlier 'not a shipped asset' verdict was wrong. The effect is POVTranslocateRenderable (engine) / BTTranslocationRenderable (our port), which loads tsphere.bgf BY FILENAME (not via the RES table, so every resource-name search missed it) and runs a collapse-on-death / expand-on-respawn sphere keyed on the SimulationState dial. Wiring already exists in btl4vid.cpp; the renderable is a no-op stub in btstubs.cpp. That's why it never shows. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

KB: archive-check verdict — no whirlwind/warp recovery asset in REL410
Searched the full pod install (nick-games/tesla4pod_extracted REL410/BT; BTL4.RES byte-identical to ours) and the whole nick-games archive: no whirl/warp/tunnel/vortex asset by filename or RES resource name, no such psfx in BTDPL.INI. The decomp drop path (DropZoneReply FUN_004bffd0) fires no effect — only Mech::Reset + the level-2 "translocated" cockpit alarm. BTPLAYER source is absent from all archives (binary-only). RP411 analog uses InitialStasisFlag (sim gate, no visual). Verdict: the pod build's respawn is mech-redrop + translocated alarm; the "blue whirlwind" is not a shipped REL410 asset.

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: tag tshd proxies in the LOADER (V toggle broke the pipeline)
User report: the shadow broke MID-SESSION -- suddenly solid opaque black and buried on any slope. The session log pinned the trigger: pressing V. The view toggle (SetViewInside) RELOADS every segment mesh through the object loader and swaps them into the render tree -- including blh_tshd.bgf -- and the reload path never called SetIsShadow(1) (only the original tree-build call site tagged it). Untagged, the entire shadow pipeline disengages: no translucent TFACTOR state block (solid black), no depth bias (buried), wrong pass. The damage-swap reloads had the same hole. Fix: tag *tshd* filenames in LoadObjectBGF itself, next to the existing all-shadow-material detector (which misses the mech proxy -- plain black material, not shadow_mtl). Every load path -- build, damage swap, view toggle -- now yields a tagged object; the drawOps alphaTest routing reads the flag downstream. User-verified live: the shadow survives repeated V toggles, translucent and slope-correct. This also likely explains the RECURRING "shadow vanishes on inclines" reports: any V toggle silently broke it; every relaunch "fixed" it. KB (locomotion.md): loader-level tag recorded as co-dependent part 5 of the shadow arrangement; the vanish-diagnostic note now lists all three causes (reload untag / gait desync / genuine burial) with check-first guidance.

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.

KB: incline shadow-vanish co-resolved with gait v5 (user-confirmed live)
The shadow report was a desync symptom, not a bias/tilt bug: the ~2-4 unit depth-bias margin is tight enough that v4's out-of-phase leg pose showing through could push the flat quad under a slope. No shadow code changed; both symptoms cleared together. Noted as a diagnostic hint (check [sync]/BT_SYNC_LOG before touching bias/tilt for this report class).

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.

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