Tooling built to recover editable source for six 'Mech chassis that exist
in the parallel FS_Build_V4H build but not in this repo. Reverse-engineers
every compiled record type in the .mw4 package format back to the .data /
.instance / .subsystems / .damage / .contents / .torso / .engine /
.armature sources the content pipeline consumes.
Nothing here is wired into the game build. It is a standalone analysis
harness run from Linux.
Package format
--------------
"#VBD" container. Directory records are [len][name][FILETIME][origSize]
[storedSize][offset], payload base at dword 0x0C. A record is stored raw
when storedSize == origSize, otherwise LZW (9->12-bit LSB-first codes,
256=clear, 257=EOF, dict from 258), per Database.cpp:451.
GameModel records are flat /Zp4 structs following the C++ inheritance
chain Entity(0) -> Mover(28) -> MWObject(80) -> Vehicle(664) -> Mech(756),
1636 bytes total. CreateMessage records follow Replicator -> Entity ->
Mover -> MWMover -> MWObject -> Vehicle -> Mech from start=16 (the
undeclared Connection__Message header), ending at 341 and padded to 344.

verify_*.py per-type round-trip verifiers
Verified round-trip across all 64 shared chassis:
.armature 2938/2976 pages .subsystems 7579/7585 keys
.data map 6071/6071 values .data trip 8291/8306 keys
.damage 6605/6605 keys .contents 7480/7480 keys
.torso+.engine 1280/1280 keys .instance 896/896 keys, 64/64 pages
armature_parts 1202/1202 .data, 1149/1202 .video
Layout-discovery lessons (documented in DECOMPILING.md)
-------------------------------------------------------
- Never let a field map be discovered by the values that verify it. A
value-matching pass reported 4288/4288 while mis-assigning 34 keys. The
map was rebuilt from header declaration order, anchored on uniquely
resolved fields.
- Read the factory, not the data. 12 .data fields and 5 Torso fields are
declared plain Stuff::Scalar but multiplied by Radians_Per_Degree in
Mech_Tool.cpp:889 / Torso_Tool.cpp.
- Strip typedefs before walking a header. A stray `typedef int AttributeID;`
masked a missing ClassID - two 4-byte errors cancelling out, caught only
by the ANCHORS assertion.
- A verifier that silently narrows its own input reports success. Braced
blocks must be hidden before splitting pages, replacing both CR and LF,
because a `Shadow={...}` block contains a line reading `[shadow]` and
splitlines() also splits on bare CR.
- NSWIZZLE is undefined, so the #else branch is live and orders members
differently. bool is 1 byte; char x[MaxStringLength] is 256.
- V4H carries stale Mech IDs (their Atlas is 5, ours 6), so 64 of 65 shared
chassis are off by one; --retarget-ids emits $(M_<Chassis>)/$(IDS_<Chassis>).
reports/ holds generated diffs. The two ~5 MB manifest-*.tsv intermediates
are gitignored; regenerate everything with run-comparison.sh.
