#96: FIX -- normalise the myomer kinetic heat term to a reference frame rate
The previous commit only instrumented. This is the behavioural change.
The binary's drive-heat integrator (FUN_004b8d18) multiplies its climb and accel
terms by the time slice but NOT the kinetic one:
heat += ratio^2 * (1+dmg) * [ (1-accEff)*|vy|*m*g*dt
+ (1-velEff)*(0.5*m*|v|^2) <-- no dt
+ (1-accEff)*|v|*|a|*m*dt ]
A per-TICK energy is a constant on a fixed-frame 1995 machine and a variable on a
modern PC: heat/second scales with frame rate, so two players on different
hardware -- or one player in a heavy scene versus an empty one -- get different
heat from identical throttle. That is a defect independent of what the pod's
rate actually was.
The kinetic term is now multiplied by (dt * kPodFrameHz), which is exactly 1.0
when dt == 1/30 and makes the result machine-independent. This is the one
deliberate divergence from a verbatim transcription of @004b8d18, and it is
marked as such in the source.
Measured, Owens at seek 4 flat out:
before crossed degradeT(1000) at ~27s, peaked 1213, settled ~710
after peak 1007, settled ~525
i.e. roughly halved at our measured ~59Hz, which is the direction the players
asked for ("too much IMO", "def need to tone down the myomer heat some").
⚠ CALIBRATION IS NOT PROVEN. 30Hz is the i860 BOARD frame ([T1],
rendering.md:177); the HOST simulation rate is not separately established, and no
fixed-timestep constant exists in the image (searched 1/15..1/60 and 30/60 Hz --
the arcade computed dt from a clock, as we do). So the reference rate is the
best-documented value, not a proven one. BT_MYO_HZ overrides it with no rebuild
so it can be calibrated by feel.
Precedent for the bug class, already logged in the KB: "trail density is
frame-rate-dependent (2/frame @60fps = 2x pod density)" (rendering.md:222).
NOT settled: whether the per-chassis ordering matches player memory (a Thor
sustaining seek 4 where a light chicken-walker cannot). Post-fix benches put the
Thor HOTTER (crosses at 40s vs the Owens at 47s), but those runs are BT_GOTO
path-driven and the acceleration term is large and path-dependent, so they are
too noisy to conclude from. The cooling data being identical across chassis IS
solid (measured, previous commit).

#96: instrument the myomer heat model -- per-mech profile CONFIRMED, overheat cause LOCATED
Two player claims, both now answered from the decomp + measurement rather than
inference.
THE EQUATION (FUN_004b8d18, constants read from the image: _DAT_004b8ee4=0.5,
_DAT_004b8ee8=0.0 (the fabs), _DAT_004b8eec=1.0):
heat += ratio^2 * (1+damageLevel) *
[ (1-accEff)*|vy|*m*g*dt climb POWER
+ (1-velEff)*(0.5*m*|v|^2) kinetic ENERGY -- NO dt
+ (1-accEff)*|v|*|a|*m*dt ] accel POWER
Our implementation already reproduces this verbatim, dt-less term included.
CLAIM 1 -- "each mech has a unique heating profile". TRUE, and working, but NOT
by the mechanism the player described. Measured across thr1/own1/mad1/vul1:
* the myomer record is IDENTICAL on every chassis
(velEff 0.995, accEff 0.8, gears 3000/5000/7000/9999, rec 2,
degradeT 1000, failT 2000, thermalMass 250000)
* the heat-family COUNT is identical too -- 6 Condensers, 1 HeatSinkBank,
1 Reservoir, 4 Generators on all four
* every cooling parameter is byte-identical Thor vs Owens (condenser
conductance 315000 / mass 420000, bank 231000 / 1.39e6, reservoir
190000 / 3.42e6)
So there is NO authored per-chassis cooling variation. The profile emerges from
the equation instead: heat ~ m*v^2, and light mechs are faster. Measured at
seek 4, flat out:
thr1 mass 70000 |v| 11.34 kinetic/tick 49026
own1 mass 35000 |v| 17.22 kinetic/tick 57350
The Owens is HALF the mass and generates 17% MORE drive heat, because v^2 beats
m. That reproduces the player's OUTCOME (a Thor sustains seek 4, a light
chicken-walker cannot) via speed, not heatsink count.
CLAIM 2 -- "it runs too hot". The kinetic term carries NO dt: it adds an ENERGY
every TICK, so its contribution per SECOND scales with the tick rate. Measured
dt here is ~0.017 (~59Hz) and variable. The other two terms are power terms and
are rate-independent. On flat ground the climb term is additionally dead --
gravity reads 0 (the carried "environment gravity unwired" open), so hills do not
heat at all right now.
NOT yet established: the 1995 tick rate the dt-less term was calibrated against.
Until that is pinned the OVERHEAT FACTOR is unquantified -- flagged, not guessed.
Adds three diagnostics, all under BT_MYO_LOG:
[myoheat] now splits climb/kinetic/accel + dt + the kinetic share
[myoparm] one line per myomer: efficiencies, gears, thermal thresholds
[hsparm] one line per heat subsystem: conductance + thermal mass
and three benches (myoheat/myoparm/myocmp) that produced the tables above.

seek-4 verification harness (BT_FORCE_SEEK) + the full supercharge/overheat
arc measured live BT_FORCE_SEEK=<idx> pins the seek gear in MyomersSimulation (env-gated bench; the eng-page toggle stays the authentic path) -- the supercharge loop was unreachable on a headless rig. Measured (Black Hawk, WALLTEST, full autodrive at gear 4): - cold: drive=1.42843 (exactly 0.9999/0.7), demand 87.85, actual run speed 53.7 u/s = 193 kph -- SUPERCHARGE (Oracle's pod figure: 182 for a 75-tonner; the 60t Black Hawk runs faster); - heat at ratio^2 = 2.04: myomer T 531 -> 1765 (deep past the 1000 degradation line); - heatFactor governor: drive 1.43 -> 1.10 -> 0.62 (the supercharged mech slows BELOW normal while cooked), coolant pulls T back (1765 -> 740), drive recovers to ~0.77, oscillates -- the mech self-settles into a thermally-limited cruise: 'top speed for less than a minute' exactly; - the hard freeze (drive -> 0: demand AND turn zeroed) is the same code path past failure temp, reachable when the coolant loop is compromised.

RETRACTION + FIX: the myomer seek->speed coupling IS in the 4.10 binary --
restored byte-grounded; the morning's removal was export-gap blindness Player testimony (Oracle, pod veteran: seek-4 humanoid = 182 kph -- the manual's printed Super Charged figure; overheat = 'freezing up') forced a re-audit of the morning's 'no dynamic myomer->speed feed' verdict. The verdict was WRONG: a raw-image capstone sweep for FPU reads of [reg+0x31C] found the consumer inside the UN-EXPORTED master-perf region -- the same decomp gap that hid the #93 crash block. Decoded @0x4a9cf2-0x4a9da4 [T1]: per frame: MAX speedEffect@0x31C over the myomer chain (+0x7AC) -> mech+0x79C mapper->speedDemand@0x128 *= it (the SPEED coupling) if |drive| <= 1e-4 (@0x4ab16c): mapper->turnDemand@0x12C = 0 (the FREEZE) Everything the manual + the veterans describe emerges: gear 4 rides speedEffect ~1.43 into the RegisterMaxOutput gait cap (base x 1.4284 -- the two mechanisms interlock: 61.5 x 1.43 = 87.9 vs cap 87.8 measured) = SUPERCHARGE; myomer heatFactor degradation slows you; overheat freezes speed AND turn; damage slows (speedEffect carries 1-damage -- #75's original premise was RIGHT and its 'falsified' close was wrong). Restored in mechmppr.cpp, byte-grounded and better than the pre-removal draft: MAX over the chain (was first-found), NO 1.0 clamp (the old clamp ate the overdrive), turn-freeze included. BTMyomersSpeedEffectOf (unclamped) replaces the deleted BTMyomersDriveOf. Verified live: healthy drive=1.0 (no speed change), collision-rattled myomers drive 0.999 -> 0.892 -> 0.742 with demand scaling in lockstep (61.5 -> 54.9 -> 45.7). KB corrected in place (subsystems WAVE 6, pod-hardware manual audit retraction, open-questions resolved) + NEW GOTCHA #21: export-gap blindness -- 'no callers in the decomp' is not 'no callers in the binary'; sweep the raw image for the operand pattern before declaring a data path dead, and when a primary source disagrees with your decomp sweep, suspect your evidence first.

myomer system COMPLETE -- the 'WAVE 6 mover cutover' was a phantom built on
a misattribution; the authentic couplings are all live
THE CORRECTION [T1]: @004b9550/@004b95b8 ('ConnectToMover'/'Disconnect
FromMover') are MechWeapon::ConfigureMappables/ChooseButton -- their +0x31C
is the weapon TriggerState and **(mech+0x128) is the CONTROLS MAPPER's
button roster (the MECHWEAP.CPP assert string + the trigger-edge detector
@004b9608 sit adjacent in the image). The binary has NO dynamic myomer->
speed feed: AvailableOutput has exactly TWO callers in the whole image --
RegisterMaxOutput (assembly) and the SeekVoltageGraph sampler -- and
speedEffect@0x31C is a published GAUGE attribute.
The authentic myomer system (now fully live):
1. drive heat (#85, this morning);
2. VITAL death -- myomers are the only authored vital=1 subsystem
(BTL4.RES res+0x48 scan): destroying them kills the mech via the #80
vital-crit path (this is also the ram-death mechanism -- myomers are a
0.35-weight collision-rattle target);
3. the assembly-time gait cap: RegisterMaxOutput @004b8ef0 raises
mech+0x7A0 to AvailableOutput(top gear) = base x ~1.4284 -- now called
(idempotent max, per tick; the 0x358 layout lock leaves no latch room)
with real OwnerBaseSpeed/OwnerMaxSpeed bridges; the old per-frame
reverseSpeedMax2 heal that would have clobbered it is garbage-guarded;
4. the ENG-page power curve at correct absolute scale (real base speed);
5. electrical sourcing (low gears run on a browned-out generator).
REMOVED (inventions): the mechmppr `speedDemand *= speedEffect` demand
multiplier + BTMyomersDriveOf + the Myomers ConnectToMover/MoverAttach
family. Damaged-but-alive myomers heat faster and drop the power curve
but do NOT slow the mech (gitea #75's premise is falsified by the binary;
the real damage slowdown is the LEG-damage gimp gait). Seek gears change
heat/sourcing/graph -- never speed.
Verified live: a mech at myomer dmg=0.234 (speedEffect attr 0.766)
beelines at full commanded speed with dmgGain=1.234 heat; 0 faults.

#85: myomer drive heat LIVE -- the five Mech motion operands were return-0
shims, so the reconstructed integrator @004b8d18 accumulated zero forever
The integrator, its gates and the heat plumbing were all reconstructed and
running -- but OwnerVelocityMag/OwnerDriveMag/OwnerVelocityY/OwnerMotionGain/
OwnerMass were cross-family compile shims returning 0.0f, so the myomers
priced ratio^2 * damageGain * 0 every tick: ice cold at any seek (Oracle's
night-7 panel-confirmed report).
Operands re-grounded against the raw disasm + decomp and mapped to NAMED
members via a complete-Mech-TU bridge (BTMechMyomerMotionSample, mech4.cpp),
per the databinding rule:
+0x1C4 vec -> localVelocity.linearMotion
+0x82C vec -> localAcceleration.linearMotion (the authentic 15-ring
smoothed AccelerationLastFrame the port already maintains)
+0x20C -> moverMass (the collision divert's cell; the old "motion
gain" label was a misread)
*(+0x250) -> environment gravity (FUN_00421e2c: vy -= **(+0x250)/tick),
via GetEnvironment()->gravityConstant
So the heat physics reads: 0.005 * 1/2 m v^2 (kinetic work, per-tick/no-dt
in the binary -- kept verbatim, frame-rate note documented) + 0.2 * m g
|vy| dt (climb power) + 0.2 * m |v||a| dt (acceleration power), all scaled
by ratio^2 and (1 + zone damage). Restored the binary's fabs(v.y) (the
draft had signed vy -- descending would have COOLED).
Authored tuning extracted from BTL4.RES (18 mech records, one shared
tuning): VelocityEfficiency=0.995, AccelerationEfficiency=0.8, gears
0.3/0.5/0.7/0.9999 rec idx 2; myomer thermal profile 77/1000/2000,
conductance 1.9e5, thermalMass 2.5e5.
Live-verified (solo arena, BT_MYO_LOG + BT_HEAT_LOG): standstill generates
~0; hard circling drove Myomers T 77 -> 1225 (past the 1000 degradation
line) and the coolant loop conducted it back to ~520 equilibrium on
slowing; damageGain live at 1.048 from grind rattle.
Known-inert remainder (filed in open-questions): the climb term reads g=0
because Mover::localEnvironment is never populated in the port
(EnvironmentZone res type 23 unwired); the mover feed (speedEffect ->
locomotion) stays WAVE 6.

myomer damage reaches the wheels, legs gimp at half structure, reverse refuses -- and an ODR trap unmasked (#75/#78)
The speed-demand site (MechControlsMapper::InterpretControls) now applies the
drive scale the mover's feed roster applied in 1995: speedDemand multiplies by
the myomers' live speedEffect (gear ratio, thermal curve, 1 - zone damage, via
the BTMyomersDriveOf bridge) and, while GIMPED, by 0.5 [T3: VGL Lynx's
"roughly 50%", BT_GIMP_SPEED overrides]. The gimp states were already being
raised -- mechdmg sets graphicAlarm 3 (left) / 4 (right) when a LegDamageZone-
flagged zone crosses half structure -- but nothing downstream ever saw them.
While gimped, reverse input is refused ("reverse disabled"), matching the
old-timers' account; the pod's audio cue rides the alarm's watchers.
Bench, one trajectory, arithmetically exact: a deterministic right-leg ramp
(the new BT_SELF_DAMAGE_ZONE harness) crosses 0.5 and the demand goes
44.837 -> 6.726 = 44.837 x 0.5 (gimp) x 0.3 (a crit-chewed myomers from the
same ramp -- the #80 crits composing with #75's scale, unprompted).
The reason "nothing downstream ever saw them" is the real find of the night,
now gotcha #23: AlarmIndicator is typedef'd to DIFFERENT TYPES per header
family -- mech.hpp says ReconAlarm (4 bytes), heat.hpp says GaugeAlarm (0x54)
-- so Mech::graphicAlarm and EVERY member after it sit at different offsets
depending on a TU's include order. mechdmg wrote level 4 and read it back;
mechmppr read 0 from the same object, same expression. No compiler error can
catch it: each TU only ever sees one definition. Until the split is audited,
cross-TU reads of the gimp level go through BTMechGimpLevel (compiled in
mechdmg's TU) -- and the same split-brain explains why the port carries the
binary's ONE movementMode cell as two live members (engine simulationState vs
graphicAlarm level) that never meet.
Also landed en route: the Myomers un-powered self-repair observed healing in
the field logs at exactly 0.011 x the authored Explosive scale per tick --
the 2026-07-29 reversal confirmed live; and Mech message 0x15 "RealMaxSpeed"
raw-decoded (@0x49f604: sets mech+0x7a0 from the message unless the +0x7a4
latch holds -- a console-tunable top speed).
Open on #78, documented in locomotion.md: the Gimp animation clips (authored
keys in the binary's model-record parser; mech2's state enum vs mech3's
reverse-fix disagree about slots 0x12-0x17 -- reconcile before wiring) and
the audio-cue binding.

the crit system, complete: two gap functions recovered, the dead sink revived, and a wrong verdict reversed (#80)
The whole critical-hit pipeline was dark, three layers deep, and one of those
layers had fooled us into a false conclusion about the 1995 binary itself.
LAYER 1 -- the trigger, recovered from the un-exported gap. The Mech MESSAGE
TABLE at 0x50bdf8 ({id, name, handler} rows) names the real
Mech::TakeDamageMessageHandler at 0x4a0230 -- message 0x12 "TakeDamage" --
plus seven sibling handlers (PlayerLink, RealMaxSpeed, BalanceCoolant,
Set/ClearBurningState, EjectPilot, DuckRequest). Inside it, the crit chance
at 0x4a0164: p = clamp(0.7 * damageLevel^2 + 0.01, 0..1), gated on the
player's simLive flag (+0x25c -- novice never crits), rolled PER BURST on the
current zone, skipping a zone already burning. Chance is ~1% on fresh armour,
~18% at half-stripped, ~58% at 90% -- crits arrive exactly as armour fails.
The handler's application loop replaces the engine base's single call, which
ignored burstCount entirely (multi-burst damage under-applied (burst-1)x).
Faithful shape: per burst, crit-roll -> CriticalHit @0049ccc4 (which routes
half the amount through the armour internally and picks ONE critical
subsystem by criticalWeight) else zone->TakeDamage -- then RE-RUN the
cylinder lottery from the impact point for the next burst, stopping early
once the mech is disabled. Multi-burst damage sprays across zones by design.
LAYER 2 -- the sink. MechSubsystem::TakeDamage was an empty btstubs stand-in;
the real body is at 0x4ac0bc (CLASSMAP had that address mislabeled
"HandleMessage"): zone damage, then on level >= 1.0 the Destroyed alarm, the
PrintState gate, the 1.0 pin, and -- for a vital subsystem -- the owner
mech's graphicAlarm to level 9, the same fall/death level the leg path
raises. That is the #28 vital-subsystem kill machinery, now real.
LAYER 3 -- the one that rewrites yesterday. The subsystem ctor DID copy
armour points + per-type scales into the private zone -- through the
ReconDamageZone PROXY, whose fields sit at struct offsets +4/+8, not the
binary's +0x140/+0x144. The floats landed on the engine object's header and
the real damageScale[] stayed zero. The 2026-07-28 experiment that "proved"
subsystem zones cannot be damaged -- and that the Myomers un-powered
self-repair was dead code in the original -- was measuring exactly this port
bug. Both verdicts reversed: the binary ctor (0x4ac7bb) initializes the zone
from the resource keys WeaponDamagePoints (required) + CriticalHitScoreBonus
(required) + Collision/Ballistic/Explosive/Laser/EnergyDamagePoints, none of
which the CSS parsed. Now parsed (with the binary's own error strings), and
the ctor writes the engine's NAMED members -- layout-parity holds, so they
land on +0x140/+0x144 faithfully. The Myomers repair branch is LIVE, in 1995
and here. KB corrected and swept (combat-damage, subsystems WAVE 6,
myomers.cpp, CLASSMAP).
Live-verified twice: [subarmor] prints real parsed scales for every subsystem
at spawn (HeatSink pts=10 scale=0.1x5, Condensers pts=5 scale=0.2x5, ...);
[critroll] landed full-chain crits in both runs (zone -> weighted pick ->
subsystem's own zone driven to 1.0 -> Destroyed); mech death/respawn and the
ammo gates un-regressed; zero crashes/asserts. Honest gaps: burst>1 spraying
is transcribed but not yet exercised live (self-damage fires burst=1), the
damageType==0 COLLISION divert (@0x49ffcc) is documented-not-reconstructed,
and the id-0x16 damage/kill report messages to the players (the authentic
stats plumbing, decoded to field level in the KB) are deferred to the #45
work.
Diags: BT_CRIT_LOG ([subarmor] + [critroll]), the existing BT_DMG_LOG.

torso twist died after a respawn: Myomers ran the inner integrator, never the wrapper
Gitea #70. Torso twist intermittently stops working after a death/respawn and stays stopped, with the generator at a full 10000V and the voltage link resolving fine. A stale state, not a live one. The Torso is a PowerWatcher that mirrors the electrical level of the subsystem it watches -- for the MadCat that is roster slot 15, Myomers -- and torso.cpp:570 holds effectiveTwistRate at 0 whenever that mirrored level is not Ready. So the question was never about the torso. It was: why does Myomers sit at NoVoltage forever? Because it never ran the state machine that would walk it back. The Myomers ctor @004b8fec stores [0x511620] into activePerformance, and that pointer resolves to 0x4b8b9c -- whose first instruction is `call 0x4b0bd0`, which is PoweredSubsystem::PoweredSubsystemSimulation. @004b8d18, the function this port had registered, is the INNER drive-heat integrator that wrapper goes on to run. We registered the inside of the onion. PoweredSubsystemSimulation is the only code that both enters NoVoltage (source == 0) and leaves it (NoVoltage -> Starting -> Ready), so a Myomers that lost power during the death/reset window had no way back out. Order is load-bearing: the base call precedes the heat-model gate in the binary. Gating first -- as this did -- also denied the electrical machine to every non-expert pilot, since OwnerAdvancedDamage() reads the +0x260 heat-model flag and that is off below veteran. Measured with BT_SELF_DAMAGE + BT_TORSO_LOG, before and after: pristine, before 48/48 Ready after 38/38 Ready post-respawn 95/97 Ready 89/89 Ready Two dead windows per respawn, now none, and the clean case stays clean. The wrapper has a tail this does not yet reconstruct: @004b8bb9-0x4b8c1e runs an effect when electricalStateAlarm == 1 and the myomer's damage zone is below 1.0, building a small vector (const 0xbc343958, about -0.011f) against the owner's localOrigin@0x100. Almost certainly the un-powered movement penalty. Flagged in the KB as T4 rather than guessed at. Worth generalizing, and noted as such in context/subsystems.md: when a subsystem's Performance address in a PTR_LAB_* slot does not match the function we reconstructed, suspect a wrapper that chains the base sim. The whole family does it -- Generator and PoweredSubsystem both lead with HeatSink::HeatSinkSimulation, and the Torso's own perf @004b5cf0 leads with UpdateWatch.

Gitea #62 FIXED: AutoConnect can re-attach again -- slot 16 is HasVoltage(source), not GetStatusFlags()
A weapon detached by two eng-page BUS MODE presses stayed dark for the REST OF
THE MISSION: no voltage, blank recharge arc, dead ready dot, will not fire.
The arcade recovers by pressing bus-mode back to Auto and letting the per-frame
auto-hunt re-tap a generator. In the port that hunt's body was UNREACHABLE.
THE DEFECT, visible in three lines of powersub.cpp:
if (modeAlarm == AutoConnect && GetStatusFlags() == 0) // outer: NOT damaged
for (...)
if (... && GetStatusFlags() != 0 && Attach(sub)) // inner: DAMAGED?!
Both call sites modelled the no-argument GetStatusFlags(), so the outer demanded
"no status flags" and the inner "some status flag", with nothing in between able
to change the value -- mutually exclusive, body never entered. The binary's
@004b0bd0 calls vtable slot +0x40 (slot 16) with TWO SHAPES: slot16(this, 0) == 0
("am I unpowered?") and slot16(this, candidate) != 0 ("would THIS generator
supply me?").
WHAT WAS ACTUALLY WRONG was narrower than the issue assumed -- the BODY was
already a faithful transcription of @004b0b5c (complete-type accessors, no raw
offsets). Only its NAME and its WIRING were wrong:
* it was called `IsSourceShorted`, asserting the INVERSE of what it computes:
state 2 is the generator's ON-LINE state (Generator::GeneratorReady, what
@004b215c's stateAlarm->2 sets) and the fabsf test requires meaningfully
non-zero output voltage. True means "live and supplying".
* it was declared NON-VIRTUAL, so it could not be the slot-16 body, and a weak
stand-in (`electricalStateAlarm == Ready`, no source arg, no voltage test)
occupied `HasVoltage()` instead.
FIX: rename to `virtual Logical HasVoltage(Subsystem *source = 0)`, delete the
stand-in, restore the two AutoConnect call shapes, and rename Myomers' slot-16
override (`HasAdequateVoltage` -> `HasVoltage`) so it actually overrides -- it
tightens the test to "at least the SELECTED SEEK voltage", which is why it
exists.
BLAST RADIUS (the issue's warning): GetStatusFlags ORs the BadPower bit 0x40 on
!HasVoltage(), and that bit feeds #47's annunciator -- so power, firing and
annunciation semantics moved together. Checked: a healthy solo mission shows
zero spurious BadPower, subsystems simulate normally, no faults.
VERIFIED with a new diagnostic hook in the codebase's existing family
(BT_POWER_DETACH_TEST=1, off by default): it reproduces the player's exact state
-- drop the voltage link and force Auto, i.e. what the second BUS MODE press
does -- so the fix can be tested without the eng-page UI. Live result:
[power] TEST: detaching Avionics (forcing Auto) -- the auto-hunt must recover it
[power] AutoConnect RE-ATTACHED Avionics -> generator GeneratorA
Before the fix that second line was impossible. BT_POWER_LOG=1 prints every
re-attach; both hooks stay for regression use.
(The file-static one-shot is deliberate: PoweredSubsystem's layout is byte-locked
by PoweredSubsystemLayoutCheck, so a test flag as an instance member would break
sizeof and every offset assert downstream.)

#55 steps 0/1/2/4: the 1995 DEATH pass restored, the arg gate made real, and 5 subsystems the respawn sweep never reached
THE HEADLINE: the port's death sweep was a total no-op, and fixing it required
fixing the arg gate in the same commit -- otherwise corpses refill their ammo.
STEP 2 -- the authentic dispatch shape:
* engine/MUNGA/SUBSYSTM.h: Subsystem::DeathShutdown gains the binary's
universal base body { DeathReset(c) } (@004ad10e). It was empty, and NO
port class overrode it, so everything the 1995 game does at death was
skipped entirely.
* mech4.cpp death sweep now passes 0, not 1 (the binary's @0049fe0c arg) --
the wreck shape: alarms/state settle, nothing refills.
* ARG PROPAGATION (mandatory once the sweep runs): AmmoBin::DeathReset is now
arg-gated exactly as @004bd26c -- refill only when arg != 0, ammoAlarm
unconditional. Ignoring the arg was harmless only while the sweep was
dead; with it restored, every corpse would have re-armed. Also forwarded
in PoweredSubsystem / HeatSink / Condenser / HeatableSubsystem / Generator
(each binary body forwards it -- verified addresses in the plan).
STEP 4 -- coverage for 5 classes that had an authentic slot-10 body but no
DeathReset, so the respawn sweep fell through to the empty base:
Torso (this is Gitea #70 -- "loosing torso twist function after a death"),
Gyroscope, Myomers, HUD, Seeker.
STEPS 0/1 -- observability + the David chain:
* Three unconditional matchlog rows: DEAD_NOTIFY (mech + resolved link),
PLAYER_LINK (player <-> vehicle), RESPAWN (mode/alive/zones/subsys/pos).
A respawn was previously INVISIBLE in the matchlog -- night 3's analysis
had to infer them from ammo arithmetic.
* Mech::PlayerLinkMessageHandler + the death dispatch site: when the engine's
one-shot registry lookup misses (no null check, no retry -> the whole
death/respawn cycle silently swallowed), recover the SAME object via the
reverse link the binary's own respawn branch walks (player+0x1FC ==
playerVehicle). Complete-type TU, no raw offsets.
* deathPending cleared in the first-spawn branch (a latch carried in would
permanently kill every later respawn -- the #57 class).
VERIFIED on the 2-pod rig (madcat vs thor, forced kills, 5 death/respawn cycles
per pod): build clean, ZERO new /FORCE unresolved externs from the 5 new
overrides; refill lines appear ONLY immediately before a Mech::Reset and NEVER
between a death and the next respawn (the corpse-refill regression this commit
had to pre-empt); all three probe rows present in both pods' matchlogs; every
DEAD_NOTIFY carried a non-null link.
DELIBERATELY DEFERRED (documented, not forgotten): the mechsub.cpp rename pair
(ResetToInitialState -> GenerateFault, ClearStatus -> the root reset @004ac22c),
deleting HeatableSubsystem::ResetToInitialState, and deleting RespawnRepair.
Those need the HeatableSubsystem vtable-slot-10 pre-flight the plan calls for,
and we have no binary image here to dump the vtable from -- guessing at it
risks the vptr-alias trap. Next session with the decomp shards open.

Issue #19: wire ToggleSeekVoltage (Myomers id 9 + energy weapons id 0xb)
Root cause -- NOT issue #2 (the experience mis-seed pins everyone to VETERAN, which PASSES the novice lockout; the gates were never the blocker). Two unwired handlers, the same silent-swallow pattern ToggleCooling had (Receiver::Receive -> NullHandler for an unregistered id): - Myomers (handler table @0x51158C {9,"ToggleSeekVoltage"@004b8a48}): the reconstruction had an EMPTY stub (the address falls in the untagged decomp gap 0x4b8837..0x4b8a8c) and never registered the id. Body reconstructed faithfully from the raw disassembly (tools/disas2.py 0x4b8a48): novice lockout (@4ac9c8) -> heat-model gate (@4ad7d4) -> press-only (msg+0xc>0) -> currentSeekVoltageIndex@0x320 = (idx+1) % (maxSeekVoltageIndex@0x32C + 1). Modulo from zero, min index not consulted, no ResetFiringState. - Emitter (energy-weapon table @0x511DB8 {0xb,"ToggleSeekVoltage"@004ba478}): the faithful body already existed as the orphaned "AdvanceSeekVoltage" (ZERO callers) -- converted to the registered message handler (same guards; cycle + ResetFiringState when not wrapping, disasm re-verified). PPC and GaussRifle copy-inherit the set; the ammo branch keeps its own id 0xb == EjectAmmo (still unwired, tracked separately). Both registered via MESSAGE_ENTRY on top of the inherited chains. Permanent diagnostics: [seek] gear log (BT_SEEK_LOG) + BT_SEEKTEST scripted dispatch harness (mech4.cpp, the cooltoggle pattern). VERIFIED headless: [seek] Myomers -> 3,0,1,2,3... and [seek] PPC_1 -> 3,0,1,2,3... (modulo-4 wrap, matching the binary's arithmetic). Awaiting the tester's live ADV-mode confirmation for the real MFD button route (the routing layer is the same streamed-EventMapping path ToggleCooling verified). KB: decomp-reference.md message-table rows marked wired. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

SeekVoltageGraph: full reconstruction -- the eng-page POWER graph + top-box eraser (Gitea #11)
The #10 audit's one WRONG: the port Execute was a bring-up no-op, so the emitter/myomer engineering pages never erased their top data box -> stale sibling-page ghosts on the shared Eng bit-plane (SYSTEM 10 PPC showing the Streak ammo box, etc). Full faithful widget landed: - btl4gau2: ctor/BecameActive/Execute/clear/ticks/cursor recovered from the capstone disasm of @004c6798/@004c6920/@004c6934/@004c6be4/@004c6c30/ @004c6c6c (Ghidra dropped every x87 arg). Plot: v=0..12000 step 1200, x=Round(response(v)*230), y=Round(v*(1/12000)*187) (ld80 @004c6bd0/@004c6d74 = exactly 1/12000); change-test samples the response at 12000V vs the 9999 activation sentinel; XOR op for tick/cursor move-by-redraw; destroyed branch centres edestryd.pcc and revives via own vtbl+0xC (BecameActive, slot 3 of PTR_0051a1fc -- vtable-dump verified). - The vtbl+0x3C sampler identified from the binary vtables: Emitter slot 15 @004bb42c = sqrt(P(v)/2.0e8), P @004bb3f4 = damageFraction*v^2*0.5* energyCoefficient; Myomers slot 15 @004b8f94 = sqrt(AvailableOutput(v)*3.6/ 350). FUN_004dd138 == sqrt (part_015.c:4026): myomers' fabs reading corrected, GetSpeedReading renamed SeekVoltageResponse. Port dispatch via complete-type bridges BTSeekVoltageSample/BTMyomersSeekSample + BTSubsystemDestroyed (databinding rule). - Emitter's AUTHENTIC attribute table recovered (binary @0x511dd4, ids 0x1D-0x25) and published: Laser*/Seek*/OutputVoltage@0x414 (currentLevel, RAW volts -- the live-cursor feed). Field renames per the table: 0x3F8 minSeekVoltageIndex / 0x3FC maxSeekVoltageIndex (static_assert-locked). The MechWeapon 0x1D OutputVoltage PORT ALIAS retired (binary table ends 0x1C; Find walks lowest-id-first, the alias shadowed the authentic row). PPC::DefaultData -> Emitter::GetAttributeIndex(). - mech4: BT_PRESET_HOLD=<n> (freeze the #9 preset cycler after n pulses) for steady-state pixel verification; BT_SEEK_LOG diag. Verified live (BLH, autofire): both #10 repro pairs held ghost-free for minutes (SYS09->SYS10 PPC, SYS02->SYS04 ERMed, SYS05->SYS06 Myomers); curves draw with live cursors; one replot per activation; quad panels/J-K-L/sec panel un-regressed.

Audio Phase 1 (AUDIO_FIDELITY F3/F4/F10/F15/F18/F20 + KB): the quick wins
F3 distance: alDistanceModel(AL_NONE); restored the commented authored distance multiply in Dynamic3D::CalculateSourceVolumeScale, added the same override to Static3D, dropped the (now inert) AL_MAX_DISTANCE writes. Far battle audio follows the authored knee/rolloff curve again, and the volume cull / voice steal / ducking chains are distance-aware. F4 volume law: AL_GAIN = volume_scale^2 at all 3 per-frame sites (Direct/ Dyn3D/Static3D) -- the GM CC7 squared curve; linear was ~+6 dB at mids. F10 doppler: alDopplerFactor(0) (AL's model ran wrong constants + sign- inverted velocity: approaching sources pitched DOWN); the AUTHORED dopplerCents (AUDIO.INI range/speed-of-sound model, decomp-proven consumer part_008.c:7466) now adds into the Dynamic3D pitch chain. F15 ConfigureActivePress: published at the MechSubsystem BASE (binary id 2, descriptor @0x50de5c -> +0x110); renamed the misnamed vitalSubsystemIndex member (the weapon ConfigureMappables handler already drives it 0/-1). Removed the invented Sensor/Myomers duplicates and RESTORED their byte- exact layouts (0x328/0x358 allocs + asserts). MechWeapon's pinned-id pad absorbed the +1 chain shift -- which matches the binary's own numbering. F18 cook-off warning: AmmoBin FireCountdownStarted -> the existing cookOffArmed @0x18C (binary table @0x512600); the countdown klaxon can fire. F20 zoom blip: L4MechControlsMapper publishes TargetRangeExponent -> the live @0x1a4 zoom member (own table chained to MechControlsMapper). KB: replaced the bogus divisionParameters+0x10 rate read with SystemClock::GetTicksPerSecond() (FUN_0044e19c is GetFrameRate -- original audio frames were CLOCK TICKS). Regression (35s drive+fire): stable; ConfigureActivePress binds real on all 9 subsystems (idle -1, zero pad redirects); FireCountdownStarted + TargetRangeExponent bind live members; attrnull 53 -> 41; chirp still dead; footfalls still fire (gain now correctly squared).

Audio: KILL THE CHIRP -- ConfigureActivePress backed real (idle -1) on Sensor+Myomers (task #50)
The obnoxious always-on clicking was the cockpit CONFIGURE-MODE ticker: an
authored looped sequence gated by an AudioIntegerTrigger with threshold -1 on
<subsystem>.ConfigureActivePress (the held-configure-button index; -1 = none).
The attribute was one of the inert-pad redirects -- the pad reads 0 = "button 0
held forever" -> the ticker Start-fired at load and pulsed 2.7/s eternally.
Found via [sendcfg]/[seqstart] traces: the first seq start immediately follows
the trigcfg(thresh=-1, onID=Start) construction on the pad address.
Fix: real int configureActivePress = -1 APPENDED to Sensor ("Avionics") and
Myomers, registered in their attribute tables. Both classes are byte-exact
factory allocs, so the sizeof locks AND the placement-new alloc constants are
bumped TOGETHER (Sensor 0x328->0x32C, Myomers 0x358->0x35C) -- the tripwire
caught a mid-layout insert (seekVoltage@0x330 shift) and a fixed-alloc overrun
before they shipped; member moved to the true tail. Wiring the live value
(EnterConfiguration/ExitConfiguration sets/clears the index) restores the
authored hold-to-configure tick later; idle -1 is the correct silent state.
VERIFIED: ProgramButton01 plays ZERO times (was the 2.7/s chirp);
ConfigureActivePress binds real (vtbl=FFFFFFFF = the -1); FootFallInt at 0.98
gain; stable.

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

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

P7: subsystem-tree alarm unification -- the whole PoweredSubsystem weapon/power subtree is byte-exact
The reconstruction modeled the binary's 0x54 AlarmIndicator (FUN_0041b9ec) with undersized
stand-ins (AlarmIndicator==ReconAlarm==4B; HeatAlarm==8B) across the entire subsystem tree, so
every field above an alarm sat at the wrong compiled offset. Retype every such stand-in to
GaugeAlarm54(0x54) and de-phantom each class against its ctor, so the whole PoweredSubsystem
subtree becomes byte-exact. An 8-agent read-only decomp-mapping workflow decoded every ctor
first; then hands-on implementation. static_assert-locked chain (verified vs the raw ctors):
HeatSink 0x1D0
-> PoweredSubsystem 0x31C retype electricalStateAlarm@0x264 + modeAlarm@0x2B8 @004b0f74
-> MechWeapon 0x3F0 retype weaponAlarm@0x350; delete 5 phantom tail fields @004b99a8
-> Emitter 0x478 delete outputVoltage/beamLengthRatio/firingArmed aliases
+ beamHit*/beamColor/beamHitData/energyRampTime phantoms;
retype beamOrientation EulerAngles->Quaternion(16B) @004bb120
-> PPC 0x478 (no own fields) @004bb888
PoweredSubsystem -> Sensor 0x328 (no alarm; 3 own fields) @004b1d18
PoweredSubsystem -> Myomers 0x358 (no alarm) @004b8fec
New systemic bug-class instances fixed (added to the CLAUDE.md checklist):
* alias field - Emitter outputVoltage==inherited rechargeLevel@0x320; beamLengthRatio==
beamScale.z@0x434; firingArmed==inherited useConfiguredPip@0x3E0
* phantom field - MechWeapon segmentReference/pipSegment/hasTarget/targetPoint/muzzlePoint
(past 0x3F0); Emitter beamHitPoint/beamImpact/beamImpactScalar/beamColor/
beamHitData/energyRampTime (binary writes inherited damageData/voltageScale
or the value is a method local)
Non-layout fixes required in the same wave:
* outputVoltage->rechargeLevel also in the compiled GAUSS.CPP:74/93 (external readers of the
removed Emitter field -- must grep EVERY TU, not just the class's own .cpp)
* MechWeapon::GetMuzzlePoint reimplemented faithfully (removed muzzlePoint collided with
Emitter's own fields at 0x3F0) via a BTResolveWeaponMuzzle void* bridge in mech4.cpp,
resolving the weapon's mount segment (inherited this+0xdc) through the owner segment table
* DetachFromVoltageSource fixed to set electricalStateAlarm not modeAlarm (raw @004b0e30
writes the 0x264 alarm)
The vehicleSubSystems aux-screen gauge raw reads (btl4gau2.cpp:868/952 at subsystem+0x2b8/+0x278)
and the Sensor RadarPercent path now read the CORRECT byte offsets (garbage under the short layout).
Verified: combat DESTROYED-in-8, 28 shots, 0 crashes, heat heatEnergy=1.34e7, every static_assert
lock passes, heapcheck-clean through construction (the phase the isolated PoweredSubsystem retype
had overflowed). LESSON: a factory-bridge runtime Check(sizeof<=alloc) does NOT fail the build --
only a static_assert sizeof lock catches alloc overflow at compile time.

P7: byte-exact re-base of the CORE heat leaf (HeatSink/Condenser/Reservoir/Generator/Myomers)
The reconstruction modeled the binary's shared alarm/connection types with undersized
stand-ins, sliding every field above them low (the 72-byte auxScreenNumber gap). Fix the
foundational heat-leaf classes byte-exact + static_assert-lock them, from the ctor decomp:
Shared types corrected:
* SubsystemConnection 4 -> 0xC (binary link node FUN_004af9cf; FUN_00417ab4 derefs +8)
* GaugeAlarm54 = 0x54 (real AlarmIndicator FUN_0041b9ec; STATUS level at +0x14,
so subsystem+0x184 == heatAlarm+0x14 == GetLevel())
WatcherGaugeAlarm now typedefs GaugeAlarm54 (Watcher branch locks stay valid).
Byte-exact + locked (ctor-verified):
* HeatSink heatEnergy@0x158 linkedSinks@0x164 heatAlarm@0x170 resource@0x1C4
pendingHeat@0x1C8, sizeof 0x1D0 (@004adda0)
* Condenser valveState@0x1D0 condenserAlarm@0x1DC (@004ae568)
* Reservoir reservoirAlarm@0x1D0 ... squirtEfficiency@0x22C, sizeof 0x230 (@4aef78)
* Generator stateAlarm@0x1FC, sizeof 0x250 (@004b225c)
* Myomers phantom moverConnection tail removed (fits 0x358)
Three systemic bug classes fixed (added to the checklist in CLAUDE.md / HARD_PROBLEMS.md):
* alias field - a subclass member re-declaring an inherited slot the ctor reuses
(Condenser refrigerationOutput==massScale@0x160; Reservoir
coolantCapacity==thermalCapacity@0x128) -> use the inherited name
* alarm-interior - a value read at alarm+0x14 modeled as a separate member
(HeatSink heatState@0x184, Reservoir injectActive@0x1e4)
-> route to alarm.GetLevel()
* phantom field - a member past the object end (Generator shortFlag@0x25C is really
*(owner+0x190)+0x25c the msg-manager, @004b0efc; Myomers
moverConnection@0x110 a write-only base slot) -> remove it
Heat conduction now reads the REAL heatEnergy=1.34e7 (not garbage); combat DESTROYED-in-8,
0 crashes, heapcheck-clean through construction.
REMAINING (measured; a distinct larger task): making PoweredSubsystem byte-exact grows it
+0x98 and cascades into MechWeapon/Emitter/PPC/Sensor/Myomers -- all model the 0x54
AlarmIndicator with 4-byte ReconAlarm / 8-byte HeatAlarm stand-ins and are short +
phantom-tailed; retyping without byte-exacting them overflows the Emitter alloc (heap
corruption). PoweredSubsystem kept on HeatAlarm(8) stand-ins (marked) pending a
subsystem-tree ALARM UNIFICATION. See docs/HARD_PROBLEMS.md P7.

subsystems: un-stub Wave 4 readouts + Wave 6 Myomers (10->15 factory cases)
WAVE 4 (standalone readouts) -- Sensor(0xBC3)/Searchlight(0xBD8)/ ThermalSight(0xBDE)/AmmoBin(0xBCB) un-stubbed via Create<Class>Subsystem bridges + Torso-style de-shim (drop cross-family shadow fields, redirect accessors to the real inherited base, static_assert layout locks). - FIX: Searchlight/ThermalSight ctors gated their Performance on the shadow segmentFlags(=0) so it NEVER installed; switched to owner->simulationFlags. - AmmoBin: retype ammoAlarm HeatAlarm->WatcherGaugeAlarm(0x54) + drop the statusState@0x40 shadow -> exact 0x22C layout. - Guard HeatWatcher::WatchSimulation against the unresolved watchedLink (null-deref exposed once these sims run; faithful fix = resolve the link). - Heat-leaf branch (Sensor) is not byte-exact -> overflow-lock only. WAVE 6 (Myomers 0xBC6, mover-coupled) -- structural un-stub, gated BT_MYOMERS (default on; =0 -> Actuator stub). Wired INERT: MyomersSimulation early-returns (advanced-damage gate stubbed) + no-op mover feed, so the live JointedMover is untouched and the gait cannot regress. De-shim drops the owner*/segmentFlags shims to fit the exact-0x358 alloc. Authentic mover/heat coupling deferred (needs messmgr 0xBD3 + reconciling the mover feed with the gait cutover). Verified: BLH tick 20->27, Mad Cat 24, combat DESTROYED un-regressed, locomotion un-regressed, 0 crashes, 0 heap detections under BT_HEAPCHECK.

Initial commit: bt411 -- standalone Windows BattleTech (Tesla 4.10 port)
Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
