The two Performance bodies fell in a Ghidra gap (@004c11b3..@004c1408), so
BeABTDirector came straight off ndisasm of the shipped CODE section. The
verdict corrects the BT411 donor twice more: FUN_0049fb54 is not
'IsLiveMech' -- it is the mech DEATH-TRANSITION test (simulation state 2 or
9; its other callers strip update-record motion bits and halt motion
integration while it holds, and our own MovementMode ledger already said
so) -- and the donor's pick loop breaks on a DYING vehicle where the
binary's jz breaks on a LIVE one. The true 1995 behavior: the camera
lingers on its mech while the 30s timer runs, cuts away THE MOMENT the
followed mech starts dying, picks the first of four ranked players with a
live vehicle, and refreshes the lock during mission end. The 'BT-specific
0x15/0x34 track message' the port invented an engine substitute for IS the
engine's CameraShip::DirectionMessage -- ID 0x15 == Entity::NextMessageID,
0x34 bytes, byte-for-byte; the RP engine's own BeADirector source
(DIRECTOR.CPP survives) is the literal structural template BT overrode
(rank-0-only, 10s, no offset -> four ranks, 30s, (0,5,0) eye).
Mech::InDeathTransition lands in mech.cpp per the census (@0049fb54, 32
bytes). The ctor's replicant gate uses the binary's own flag test --
entity-side simulationFlags arrive live via the MakeMessage, unlike the
subsystem masters still waiting on the stream builders.
Stubs: 11 across 9 files (the 8 authoring CSS fns + the L4NET trio).
Pod-role soak clean; the director's live test rides the operator's
camera-egg / mission-review session.

The reconstructed tree now produces a runnable binary with the authentic
1995 toolchain (BC4.52 / tlink32 / DPMI32):
- BTL4.CPP main TU reconstructed from the 4.11 Ghidra decomp (FUN_0040109c)
+ the 4.10 binary's own string pool + surviving RPL4TOOL.CPP house style;
probe_main.cpp scaffold retired (BTL4.NOTES.md documents every decoded call)
- L4NET.CPP staged: L4NetworkManager ctor/dtor + 10 vtable-pulled virtuals
(standalone-benign ones no-op, network ones Fail loudly) + NetNub client
globals (Net_Common_Ptr=NULL routes L4File to its plain-DOS path)
- build410.sh: libs now built in the AUTHENTIC makefile member order
(MUNGA.MAK / mungal4.mak / BT.MAK / BTL4.MAK). Order is load-bearing:
tlink emits static-init records in module pull order, and alphabetical
order booted into a null-vptr crash (IcomManager::ClassDerivations
constructing before parent NetworkClient::ClassDerivations). Also fixed
stage_link to the proven 32-bit lib set (SOSDBXC+SOSMBXC, no WATTCPLG)
- BOXTREE.HPP MemoryBlock unify, BTL4GRND notify stubs, remaining engine
backfills (audio/gauge/resource/stream TUs) that closed the deep ledger
Smoke test (DOSBox-X + 32RTM, copy of the pod BT tree, our exe swapped in):
BattleTech v4.10
BTL4Application::BTL4Application
l4net.cpp(22): L4NetworkManager -- l4net.cpp not yet reconstructed
Static init, main, -egg parse, BTL4.RES load (version 1.0.6 check passes),
ApplicationManager and the BTL4Application ctor chain all execute real
reconstructed code; boot halts at the first staged Fail() as designed.
Next brick: the real l4net.cpp body.

The tlink32 campaign after the checkpoint: eleven engine bodies back-dated
from BT412 (rotation player team explode dropzone terrain cultural receiver
subsystm app l4gauge - the Application core included), the WinTesla-ectomy
handled by backdate.py's new unwrap rules (accessor-fn statics -> 1995 static
objects, decl rewrites, pointer->reference Derivation ctor, 2007 windowed-
gauge/console-marshal/idle-pump excisions), staged statics TUs opened for the
game classes (MECH/BTPLAYER/BTDIRECT/PROJTILE/MISSILE/BTL4MPPR .CPP + L4APP/
NETWORK engine statics).
State: every compiled symbol short of the shallow graph RESOLVED (the 52- and
17-symbol ledgers burned to zero); with 32stub.exe in place the linker reaches
full vtable closure and emits the deep ledger (~210 symbols, UNRESOLVED-
LEDGER.txt): remaining engine bodies (objstrm cstr gauge/gaugrend graphics
pixelmap palette resfile ray scnrole explosion-table), the DOS driver extern
layer (_SVGA*/_PCSerial*/_PCSPAK*/joystick/netnub/sosMIDI), the full L4App
body, and the real game-TU frontier (Mech::Make et al.). Recipe proven for
every category.
