ConsolidateAndSendDamage @0049b784 fully implemented: the beam path submits
into AddDamageMessage; each messmgr tick builds ONE Entity::
TakeDamageStreamMessage (id 0x13; wire-verified 0x34+4+Nx12) with the
common impact record + appended {type, amount, subsystemID} entries and
Dispatches it at the victim -- the T0 handler (ENTITY.cpp:817) re-splits
into per-record TakeDamage; replicants reroute cross-pod. Real
ResolveExplosionID (firing weapon's +0x3E4, guarded) + SubmitExplosion via
the Explosion::Make port; TWO chain-purge bugs fixed (the "iterator dtor
clears it" assumption was wrong -- records re-applied every tick, observed
1->2->3->4 double-counting). @004b9728 identity corrected (SendDamageMessage,
not DrawWeaponPip). Verified solo: 25 clean single-record consolidations ->
kill -> death transition. Residue: weapon-side submission awaits the
damage-economy reconciliation (authored 0.25-scale vs kShotDamage=12).

Binary census [T1]: mech+0x434 has exactly 2 writers (ctor init + factory
case 0xBD3) and ONE reader (@0x4b984b in MechWeapon::SendDamageMessage
@004b9728) -- pure message-manager semantics, nothing mapper-like. The
factory case now builds the real SubsystemMessageManager (ctor @0049bca4,
0x130, ConsolidateAndSendDamage Performance); the misbuilt MechControlsMapper
squatter is evicted. Every mapper consumer re-pointed to MappingMapper()
(roster slot 0 = the binary's **(mech+0x128); SetMappingSubsystem @0049fe40
touches ONLY slot 0 -- its [0x10d] mirror removed). Non-viewpoint mechs get
a slot-0 demand LATCH (base mapper, [T3] accommodation -- the binary leaves
slot 0 NULL off-viewpoint but never drives/animates those paths; ours does).
Verified: solo drive+gait clean; MP replicant gait through the latch (full
run lifecycle); 3x kill/respawn cycle with type-6 records on the observer.
Remaining (task #7 tail): the messmgr's consolidated TakeDamageStream send +
weapon-path routing (@004b9728 real body).

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.
