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.
