Saved bounded linear calculation checks
4 saved linear calculations were independently checked.
All four proposals retain or reduce the feasible anchor objective and report solver success. This checks the revised bounded linear calculation on the matched saved matrices; it does not qualify the complete nonlinear optimizer or establish calibration coverage.
| Saved fit | Starting cost | Returned linear cost | Worse than zero step? |
|---|---|---|---|
| Earlier control, start 0 | 228.314752962 | 228.314752962 | No |
| Earlier control, start 1 | 228.314752962 | 228.314752962 | No |
| Failed case, start 0 | 201.208295996 | 201.208295996 | No |
| Failed case, start 1 | 201.208295996 | 201.208295996 | No |
The runner accepted 4/4 task envelopes. Every returned outcome and charged solve is retained; no closed study was restarted.
Every calculation retains all 26 nuisance directions and the original physical bounds. It uses the exact saved final linearization; it is not a native replay at a different anchor. No original fit is relabeled, no calibration threshold is established and validation stays blocked.
Next: reproduce the linear-solver failure with an independent known-answer problem, then qualify a correction before any new campaign.
