The weekend's crash family root-caused under cdb: SourceSet.sources[5]
receives the AllExplosion death preset's 25 streamed voices --
RequestAudioChannels wrote 20 OpenAL source ids past the array, smashing
the neighbouring heap object (Release: a vtable overwritten with a source
id -> delayed silent AV at AudioControlEvent::Send; Debug: CRT heap-
corruption abort in the death Explosion's audio teardown). Explains all
three #12 crash flavors (solo enemy kill -- stack-confirmed; MP self-
death; MP peer PEER_DOWN cascade -- same generic teardown).
Fix: sources[] sized to AUDIO_SOURCESET_CAPACITY=25, static_assert
lockstep with MAX_PRESET_SAMPLES, + defence-in-depth clamps at the ctor
and acquisition sites. Soak: 26+ deaths across glass AND pod builds
under cdb, zero faults, full wreck lifecycle every time. Gotchas S21:
the fixed-array-vs-streamed-count overflow class + sweep note.
Awaiting human verification: the MP death-and-survive session.

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.
