#60 PART 2: the RE-EXPORT -- dark code 90KB -> 41KB, coverage 87.3% -> 93.5%

Browse Source 
Installed JDK 21 + Ghidra 12.1.2 (no admin, %LOCALAPPDATA%\bt411-tools beside
DXSDK/cmake; runner uses 8.3 SHORT paths because Ghidra's .bat expands
%JAVA_HOME% unquoted and the profile has a space).

New tooling: reference/ghidra_scripts/ExportGaps.java -- ExportAll's exact
output contract PLUS a gap-fill pass (force disassembly + createFunction at
E8 call targets outside functions, data->code pointers at a plausible
prologue, and the census's discovered starts; iterated to a fixpoint,
logged to gapfill_report.tsv).  tools/ghidra_reexport.sh (headless runner,
'reprocess' mode) and tools/gapdiff.py (score two censused exports);
gapcensus.py now censuses any export dir.

Results: 6267 -> 6472 functions (+205 created in 2 rounds: 195 census
starts, 6 call targets, 4 data pointers; 56.1KB newly covered), ZERO
decompile failures.  Dark real code 90.4 -> 40.8 KB (54.8% recovered);
game-side dark 53.1 -> 21.1 KB; regions 428 -> 321.  EVERY historically
dark function now has pseudocode -- including @0x4c05c4 VehicleDead, the
absence that opened this issue.

VALIDATION: the new pseudocode confirms this week's hand reconstruction of
the crouch field-for-field (mapPosture/duckState/squatCapable/myomerEff/
novice gate/SetLegAnimation/ForceUpdate/stability alarm) -- and exposed one
branch the raw pass missed: AIRBORNE AUTO-RISE (mode 3|4 && legState 1 ->
forced squ), now implemented in mech4.cpp and re-benched un-regressed.

PROMOTION: the re-export is canonical reference/decomp/; the previous export
is preserved at reference/decomp/archive_2025export/ so old
`part_0NN.c:LINE` citations still resolve (addresses are stable across both;
line/shard membership is NOT -- cite @ADDR).

New lead recorded: @0x4c0904 is the MASTER BTPlayer Performance (team
resolution, EndMission console post, score heartbeat) -- our @0x4c083c
PlayerSimulation attribution needs a re-check.  KB: source-completeness,
gotcha #20 (the rule is cheap now -- look it up), CLAUDE.md router/layout.
Log: phases/phase-04-gap-census.md.
