Input-audit cause #1: revive the Avionics power bank + add the unhandled-message trace
THE CLASS OF BUG. A default-constructed Receiver::MessageHandlerSet is a total blackhole: entryCount 0 and NO parent chain, so Find() returns NullHandler for every id and Receiver::Receive dropped the message with no log, no counter, nothing. docs/INPUT_PATH_AUDIT.md ranked this systemic cause #1; running its own lint finds SEVEN such sets (Sensor, Searchlight, ThermalSight, Gyroscope, MechTech, SubsystemMessageManager, Torso). It is also why generators cannot be switched off (#53) -- same shape. FIX 1 -- Sensor / Avionics (the big one). The streamed mappings aim 108 records across the 18 mechs at it: the MFD2 ENG1 power bank, 6 clickable buttons plus keys F5-F9 (route Avionics power to generators A-D, gen mode, coolant cut). All silently swallowed. Sensor needed NO handlers of its own -- ids 4-8 already live on PoweredSubsystem, which chains HeatSink for id 3, covering the whole 3-8 range those buttons send. It only ever needed to CHAIN, which is exactly why the byte-identical bank on ENG2 works (Myomers chains, myomers.cpp:88-100; Sensor did not). Added Sensor::GetMessageHandlers() with the same function-local-static idiom and pointed DefaultData at it instead of the empty set. VERIFIED LIVE (scratchpad/avionics.py -- pages MFD2 and presses the bank): [gensel] Avionics -> GeneratorA (tapped) ... B, C, D [gensel] Avionics mode -> 2 i.e. Avionics now behaves exactly like Myomers. 24 handler hits, 0 unhandled. FIX 2 -- the standing guard. Receiver::Receive now logs once per (class, message id) pair when no handler is found: '[msg] UNHANDLED: <class> has no handler for message id N -- silently dropped (is its MessageHandlerSet chained?)'. Once-per-pair on purpose, since some ids broadcast every frame. This one line would have printed Avionics, Searchlight, ThermalSight, crouch and all four generator buttons on the first boot instead of costing us months of player reports. Uses SharedData::derivedClasses -> Derivation::className. DEFERRED, with reasons (not guessed at): Searchlight's ToggleLamp body exists but is unreachable -- it needs a correctly-typed forwarder (Receiver::Handler is void(const Message*); ToggleLamp is Logical(Message&), so a cast would be UB that happens to work on x86) AND an id check, because its id 3 collides with HeatSink's ToggleCooling and I have not traced whether PowerWatcher's chain reaches HeatSink. #53 needs more than chaining: ToggleGeneratorOnOff @004b1ed0 has no body at all.

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.

gauge-complete P4a: heat-leaf data fixes (radar heat-degradation authentic)
The gauge-complete-decode workflow found the "deep heat-leaf byte-exact re-base" is STALE -- the leaf layout already shipped byte-exact (alarm-unification/P7), and the real work is a small misidentified-field data fix (highest value, lowest risk): - Sensor radarPercent read the INHERITED heatEnergy (~1.3e7) -> hugely negative -> needed a bring-up guard forcing it to 1.0. The binary (@004b1c4c:1829) reads *(this[0x38]+0x158) = the subsystem's OWN DamageZone::damageLevel [0,1] (0 intact .. 1 destroyed). Fixed: radarPercent = RadarBaseline - GetSubsystemDamageLevel(); guard DELETED (damageLevel is engine-clamped). So the radar authentically degrades with sensor structural damage (RadarBaseline-damage, x0.5 on DegradationHeat, 0 on Failure). - New databinding-SAFE accessor MechSubsystem::GetSubsystemDamageLevel()/Set... reads the ENGINE DamageZone::damageLevel NAMED member (NOT the ReconDamageZone proxy, whose offset-0 structureLevel aliases the vtable ptr as a float = garbage). - HeatSink::HandleMessage msg==1: same misidentification -> SetSubsystemDamageLevel(0.5) (was linkedSinks->heatEnergy=0.5, wrong object+field). - MyomerCluster seek lamp: subsys+0x800 (OOB for 0x358 Myomers) -> currentSeekVoltageIndex @0x320 (the Emitter+0x3f0 analog; INFERRED -- ctor not in the assert-anchored export). - numericSpeed (~225 vs 61.5): verified NOT A BUG (NumericDisplaySpeed applies x3.6; the feed is correct u/s) -- closed, no code. No layout change (already byte-exact); pure data-read retargets. Verified DBASE+dev gauges: no crash, combat un-regressed (TARGET DESTROYED). (radarPercent degrade is only OBSERVABLE once per-subsystem damage routes to each engine DamageZone -- a separate task; today the sensor is undamaged so radarPercent = full 1.0, which is correct.)

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.

gauges: register + wire the map (radar) -- the tactical display renders
MapDisplay (the radar/threat-map gauge, btl4rdr.cpp) was fully reconstructed (ctor + Execute + DrawViewWedge/DrawStatic/DrawMoving/DrawNames) but never registered and its data attributes never published. Wire it up end-to-end: DATA (the attributes the map binds): * Mech table extended to the full 0x15..0x38 (was the 0x21 prefix): add RadarRange@0x2f -> radarRange, RadarLinearPosition@0x30 -> radarLinearPosition (Point3D* -> &localOrigin.linearPosition), RadarAngularPosition@0x31 -> radarAngularPosition (Quaternion* -> &localOrigin.angularPosition), DuckState @0x37 -> duckState; the rest bind the shared attrPad (kept dense so Find can't strcmp a gap). New members set in the Mech ctor; radarRange defaults to 500 (SetTargetRange is still stubbed) so nearby contacts are on-scale. The map's position/angle attributes resolve to Point3D**/Quaternion** (AttributePointer is int Simulation::*, so the ATTRIBUTE_ENTRY reinterpret binds pointer members fine -- verified live: posPtr/anglePtr resolve). * Sensor (named "Avionics") publishes RadarPercent/SelfTest/BadVoltage: define Sensor::AttributePointers[] + build the previously-empty Sensor::AttributeIndex chained to PoweredSubsystem::GetAttributeIndex() (= HeatSink's dense index). WIDGET (the registration glue -- NOT in the assert-anchored decomp, so reconstructed from the config + ctor): * MapDisplay::methodDescription (config "map") + MapDisplay::Make. The offset_position keyword "center"/"bottom" is typed as a STRING and converted in Make, avoiding a ModeManager named-constant registration. Registered in BTL4MethodDescription[] (btl4grnd.cpp now includes btl4rdr.hpp). Three crash fixes exposed once the map ran (each a pre-existing stub the map is the first consumer of): * Sensor radarPercent went hugely negative (RadarBaseline - HeatMasterEnergy(), where the inherited heatEnergy is un-normalized in the not-byte-exact heat-leaf branch) -> the radar reported non-operational. Guard: treat an out-of-[0,1] heat term as no penalty (marked bring-up; real overheat penalty needs the heat normalization). * ResolveOperatorEntity was a stub returning NULL -> EntityPosition(NULL) crashed CalculateBounds. Fixed to the renderer linked-entity + application viewpoint fallback (same as HeadingPointer). * MapName::ExtractFromEntity didn't guard a NULL entity (the binary's Verify(False) iterator-mismatch path compiles out at DEBUG_LEVEL 0) -> EntityPosition(NULL). Guarded. Verified live (BT_DEV_GAUGES): the radar now draws the view wedge (the mech's 180-deg FOV cone) and completes the full wedge/static/moving/names cycle with operating=1, cap=1, scale=500, position/angle resolved, 0 crashes. Combat un- regressed (TARGET DESTROYED after 8 hits), heap-clean under BT_HEAPCHECK. Permanent gated diagnostic: BT_MAP_LOG traces the phase/draw pipeline. Contacts show 0 (the spatial-query entity classification is a follow-up); DuckState now resolves for the duck button too. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

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.
