Live definition objects carry no name, so identity comes from the values:
unit_signatures.rs prints (HP, Size_X/Y/Z) for every disc unit and vessel, and a
live object is the record whose known fields it reproduces. 7 of 14 match a disc
record outright; the other 7 match nothing because their records default a field
-- 18 of 23 vessel records are missing at least one, nearly always Size_Y.
Matching each single-default record against the live object that reproduces its
remaining fields resolves 13 values (Destroyer 200, Cruiser 600/700, ASFrigate
80, ADAN Destroyer 300, Acropolis 400, ISCMissile 300, plus _Inv/_EX variants).
Every one equals that unit's Size_X, so the engine's own parsed definitions
confirm the statically-derived inheritance rule.
Limits stated: variants share one live object, and the ...Ratio/...Count family
is not resolved -- their offsets in the live object are still unknown.

The runtime track is unblocked. Two environment facts cost most of the effort:
audio must be --audio --apu=sdl WITH SDL_AUDIODRIVER=dummy (muting with --apu=nop
fills the log with CreateDriver failures and the guest never passes the movie),
and everything must happen inside ONE blocking foreground call because anything
outliving its call is reaped. Boot is 25s to the flight HUD once caches are warm,
which is what makes launch-and-dump fit in one call. numpy/PIL are absent so the
analysis scripts do not run; gmem.py is stdlib and does.
Result: 14 live definition objects dumped (vtable 0x820af844, 96 words each).
The +0x54 column reads as HP across three orders of magnitude and +0x30..0x38 as
Size_X/Y/Z, corroborating the earlier single-snapshot layout, and five of the
fourteen have Size_Y == Size_X exactly, supporting the inheritance default rule.
Open: no name/id field in the first 96 words, so objects are not yet matched to
their disc records.
