The last stretch: nearby field-model endpoints

The specified-field-globe primary and repeat solutions for the last unresolved stretch agree closely. Their remaining local checks involve unstable calibration corrections and neighboring timing boundaries. A separate zero-field-globe timing disagreement remains about 57 milliseconds wide.

This bounded trial applies the qualified range-scaled affine correction and clock checks to the four nearby specified-field endpoints, under both processing assumptions. It preserves the original full parameters, measurements, physical bounds, receiver weights and native stopping limits.

Two fresh controls and four target checks have a combined ceiling of 110 native evaluations, with four total numerical threads, no optimizer starts and no retries. Each processing case needs its own passing primary/repeat comparison. All original failures remain recorded.

Even a complete pass cannot resolve the stretch by itself. The zero-field-globe timing profile and complete model/case/repeat review remain separate requirements. Published findings stay 52 globe / 0 flat / 1 unresolved.

Completed: all six checks passed in 100 native evaluations, including both case-specific repeat comparisons. The completed allowance cannot be reused. The separate zero-field timing profiles address the remaining timing disagreement; no disposition changes yet.
