The 0xBBE heat-sink BANK was built as a plain HeatSink, so the numeric-R
cockpit gauge binding HeatSink/AmbientTemperature (L4GAUGE.CFG:4552) had
no publisher -> the LAST unresolved config attribute.
Reconstruct AggregateHeatSink : HeatSink (ctor @4ae8d0, own GUID 0x50e590),
byte-exact + static_assert-locked (heatSinkCount@0x1D0, ambientTemperature
@0x1D4=300, helper@0x1D8 0xC link node, sizeof 0x1E4 == factory alloc @9993).
Publish HeatSinkCount + AmbientTemperature via a dense-prefix attribute table
chained to HeatSink::NextAttributeID (shared HeatSink table unchanged, so
CoolantMass/CoolantCapacity keep resolving). Move CreateHeatSinkBankSubsystem
into heatfamily_reslice.cpp (needs the class def) and build the real class at
factory case 0xBBE; mech.cpp unchanged.
DELIBERATE DEVIATION (documented in the class): keep the base HeatSinkSimulation
the HeatSink ctor installs; do NOT reimplement the authentic Performance @4ae73c
-- it derefs a raw self+0xE0 -> [+0x158] that does not map in our compiled layout
(AV/NaN, and runs for EVERY mech), and ambientTemperature is a frozen constant so
the gauge reads 300 either way. Authentic relaxation model deferred.
Verified: [attr] HeatSink/AmbientTemperature OK; all 50 config attribute
bindings resolve (0 NULL); no every-mech crash; combat TARGET DESTROYED,
FIRED #41+, un-regressed.

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.
