Curvature after the shared calibration terms
2/2 saved-data diagnostics pass.
| Processing | Shared-source RMS | With residual derivative correction | Probes improved |
|---|---|---|---|
| Zero removal | 9.068310 m | 0.641297 m | 6/6 |
| Profiled removal | 45.353416 m | 3.278617 m | 6/6 |
All comparisons use the same twelve fixed generated points and six saved epochs. The correction applies to the error remaining after the 27 physical and 24 shared source terms, with the source explicitly reanchored at the reference. No point or coefficient is fitted.
This is not a certified bound or an aircraft confidence interval. Known probe derivatives diagnose the approximation; they are not supplied as unknown aircraft calibration. The software checks include a higher-order counterexample. No source maps are invented for other epochs and no old training-conditioned radii are transferred.
No new native integration, LP proposals or aircraft fitting is performed. Whole-period coverage, numerical/timing treatment and the aircraft observation-error law remain separate requirements before new withheld predictions.
