The common matrix component passes its qualification
All 24 generated controls pass. Independent rotation and reciprocal-gain calculations check 1,536 probes, 1,296 derivative evaluations and 6,144 weighted matrix identities. All 27 physical derivative columns remain; the augmented design retains 51 columns including the earlier and new shared errors.
This supplies the first component required by the propagation diagnosis: the same calibration matrix can act on changing raw force samples at every epoch, with its nonlinear error represented once. It does not yet integrate that term or establish narrower complete prediction ranges.
The next derivation must preserve the exact midpoint update after factoring out the matrix-weighted raw-force integrals. It must retain Coriolis, transport, the common acceleration term, lever effects and coordinate metrics. A common time offset changes those raw-force integrals, so its cross terms need explicit bounds. The current component's fixed-vector identity does not cover them.
Native propagation, a typed 51-column training/prediction interface and the full six-case/eight-sector comparison remain separate gates. No original aircraft measurements, native integration calls or observed fits were used. The 53-stretch empirical findings and scientific abstention are unchanged.
