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.

Locomotion: replace task-#64 trn stand-ins with the AUTHENTIC dispatcher (disasm-decoded)
The turn-in-place dispatcher lives in the master-perf gap 0x4a9b5c-0x4ab188 that Ghidra never lifted. Disassembled it with objdump (scratchpad/masterperf.asm) and hand-decoded the real logic, replacing the two [T3] stand-ins I had invented: - Entry gate was `commandedSpeed < 0.25*standSpeed` (a near-zero guess). AUTHENTIC (0x4aa505): arm trn when TURNING (|angVel|>1e-4, port proxy = turnDemand deadband) AND speed in the FULL [0, standSpeed] sub-walk range AND turnCapable. trn is gated on TURNING, not on being slow. - Case-4 exit had a ×4 fast-forward + SetLegAnimation(5) invention. Restored the VERBATIM decompiled leg-SM exits (part_012.c:12013): standSpeed<spd or reverse -> Standing, else advance the pivot. Added the master-perf turn-STOP exit (0x4aa5c6): turn stopped -> Standing + legResetLatch=1 (folded into case 4 since the port has no separate master-perf frame). - Body case-4 twin mirrors the authentic exits (mj=0, tracks state for lockstep). The fast-forward was invented to dodge a turn->walk stutter that was ACTUALLY the body channel leaking joints (mj=1) -- already root-caused + fixed by mj=0. The trn->walk seam (legFrm7 cycle-end -> swr legFrm1) is the authentic pose-matched boundary and the same seam the fast-forward version hit, just at the correct release speed. Also decoded (documented, not yet wired) the authentic turn-RATE lerp (walkingTurnRate@0x574 -> runningTurnRate@0x578 by speed; angVel = turnDemand*rate); the bring-up drive still yaws at the constant kDriveTurnRate. Headless-verified (BT_AUTODRIVE/BT_FORCE_TURN/BT_WALK_DELAY/BT_GAIT_TRACE): turn-in- place enters state 4, ramp past standSpeed -> 4->stand->swr->walk, both channels in lockstep. Feel re-verification pending. [T1 logic / T2 runtime] Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

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).

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).

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.

context-system: complete migration -> CLAUDE.md is now a 160-line router (zero context lost)
Full migration of the 2236-line monolithic CLAUDE.md into the progressive-context knowledge graph (per spark-lesson / expert-seed.md), so the deep RE knowledge loads on-demand instead of every session. ZERO CONTEXT LOST: - docs/PROGRESS_LOG.md = the complete old CLAUDE.md, VERBATIM (byte-identical) -- the lossless safety net + the "full detail" quick-lookup fallback. - 18 context/*.md topic files (1343 lines) digest every section (§1-3 -> project-overview, §4 -> content-archives, §5 -> asset-formats/bgf-format, §5a -> source-completeness, §5b/§8 -> wintesla-port, §7/§10 -> locomotion, §10a -> build-and-run, §10b -> reconstruction-method, §10c -> combat-damage + reconstruction-gotchas, §10d -> subsystems, render notes -> rendering, gauges -> gauges-hud, MP -> multiplayer, §9 -> open-questions). - reference/glossary.yaml (53 terms). decomp-reference.md = the offsets/ClassIDs/addresses hub. CLAUDE.md (160 lines) = router: identity, answer/reason protocols, quick-lookup table, evidence tiers (T0 engine-truth / T1 decompiled+verified / T2 reconstructed+runtime / T3 guarded / T4 hypothesis), conventions + DO-NOT (the systemic bug classes), structure. Retains the load-bearing work directives (build recipe pointer, "keep current" mandate). Knowledge graph validates CLEAN (scratchpad/checkctx.py -- all [[links]] + quick-lookup + docs refs resolve; [[name]] -> topic file or glossary term). docs/*.md ledgers stay as the detailed logs; context/*.md are the curated digests that route into them.
