2196ac112d re: unit definitions are parsed at stage load, not on wave spawn
Counted the definition objects at three points in Stage 02 -- just after
take-off, ~12 min into combat, and after GAME OVER: 14 objects, same 14 IDs
each time. Capturing a stage therefore costs one load and one snapshot; the
mission does not have to be played or survived.

2fa4c33d1a re: solve the runtime Unit (craft/vessel) struct from live guest memory
Craft stats were the last parked Route-B target: the Hangar exposes only a
weight class, and in menus the flight-model object is not instantiated at all.
It is instantiated in-mission, so this reads it there.

The definition class is discovered rather than assumed (unit_discover.py):
scanning for pointers to the disc ID strings and tallying the word behind each
pointer site picks out vtable 0x820af844 -- one object per unit ID, name-record
pointer at +0x04, string at +0x10, exactly the Weapon shape. The neighbouring
class 0x820af030 is the spawned entity, not the definition; the two are told
apart by one-object-per-ID and by 14/14 objects being byte-identical across two
snapshots 12 minutes and one firefight apart.

22 fields bind with zero contradictions on >=3 distinct values. Beyond that,
the Maneuver sub-record turns out to be laid out in schema declaration order,
4 bytes per field, base 0x9c with a two-slot gap after AA_Roll_Min -- 29
independently solved anchors fit two exact bases with no conflicts. That rule
pins five fields NO unit table ever values (PitchDragFactor, RollDragFactor,
DragFactorThreshold, ArterBurner_Acc, DecPitchFactor); PitchDrag == RollDrag ==
the disc's YawDrag on 18/18 units corroborates the interpolation.

Angles are float32 radians at runtime and degrees on disc.

Coverage is 18 of 110 units: unlike weapons, unit definitions are instantiated
per stage, so it grows by visiting missions. The AI-behaviour tail of Maneuver
is explicitly NOT resolved and marked tentative in the CSV.

Captured from Xenia Canary (BASIC CONTROLS tutorial + Stage 02 from save 01).
