Elapsed 141.4 seconds. Reconciled 48/48 source setups, 96/96 interval maps, 48/48 coupling audits, 48/48 contractions, 288/288 LP proposals, 1152/1,152 exact support checks and 6/48 truth audits.

The original native expressions, physical bounds, coefficients and error allowances are unchanged. The new constraints preserve the complete static calibration relationship. All 78 coordinates remain; the 27 product coordinates add no physical freedom. Generated truth is checked only after bounds are saved.

These generated 7.2-second cases do not establish full-flight uncertainty or calibrated observational coverage. There were no new native predictions, integration bounds, original-aircraft reads or observed fits.
