Document the cockpit-gauge attribute-pointer system in GAUGE_COMPOSITE.md
(§Attribute wave) and CLAUDE.md §10: how a Subsystem/Attribute or bare-Attribute
binding resolves (ParseAttribute -> FindSubsystem/GetName -> GetAttributePointer
-> activeAttributeIndex), what a class must publish (AttributeID enum +
AttributePointers[] + GetAttributeIndex chained + DefaultData wiring), the
DENSE-TABLE HAZARD (Build leaves gap slots uninitialized, Find strcmps every
slot -> tables must be a dense prefix), and the base-primitive vs BT-specific
widget split. Records the 4 committed increments (HeatSink table, Mech table,
vertBar, segmentArcRatio) and the follow-ups (oneOfSeveralPixInt/map/PlayerStatus/
vehicleSubSystems, the #if0'd HeatSink-bank AmbientTemperature, the Reservoir
coolantCapacity shadow).
Promote the two reverse-engineering helpers from the session scratchpad into
tools/ (durable): disas2.py (capstone + PE parse -- recovers x87 float math
Ghidra drops; FUN_004dcd94=round, FUN_004dcd00=fabs) and vtdump.py (dump a class
vtable to find an override the assert-anchored decomp never exported, e.g.
SegmentArcRatio::Execute). Doc references updated scratchpad/ -> tools/.

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.
