Two exhaustive probes agree on the same 15 records. The six Shift-JIS type words occur in the six GP_MAIN_GAME_* paks and nowhere else, and a disc-wide sweep of every parsed record name for a wildcard shape (???, *, ###, NNN, <...>) returns 7 distinct names - exactly the seven already in the schema: Turret_???, Hatch_???, Bridge_???, Thruster_???, ShieldGenerator_???, Versatile_???, NS_*, each x6. So the weapon datasheet, the arsenal item and StageResource ship NO schema; the unit datasheet is the only structure the disc describes to itself. Wildcard field names are confined to the schema records too - NozzleSpec_???, NozzleFrame_???, CannonFrame_???, MuzzleFrame_???. No untyped gaps either. The full residual is 30 slots and every one holds a sample value rather than a missing type: 28 booleans spelled Yes, plus Generic.ID = Ship_ and Generic.Type = Vessel. The booleans follow one pattern - the six destructible part types each carry the same four-boolean core (IsDestructible, IsInvolved, IsRadarVisible, IsShielded), Turret_??? adds IsAuto, Generic carries only IsDestructible, and NS_* has its own pair AttenuationAlpha / AttenuationVolume. 28 + 2 = 30; 7 fully-typed records + 8 with examples = 15. The third result is a refutation of my own instrument. Testing the four genuinely-undeclared effects against the 166 .xpr packages put eff_f0002 and eff_f0002_barn in Base.xpr and found nothing for eff_e0044 or eff_h308 - but the control kills the negative: eff_n0071, which we measured LIVE as an Explosion record's ExplosionFxModel, also returns nothing from the same search. A known-live name the test cannot find means the test has no power here. Only the positive half counts: eff_f0002/_barn do ship. Nothing follows about eff_e0044 or eff_h308, and the earlier "no mesh" remarks about eff_e0058/_e0059/_e0060 are weaker than written - absent from a byte search over .xpr is not absent from the disc. How an effect mesh is actually reached is now the open question, since eff_n0071 is not a plain name string in any of the 166 packages. All sixteen artefacts byte-identical.
