Completed clustered-boundary comparison

Shape result: globe. All six primary fits passed: True. Both controls passed: True. Required repeat agreement passed: True.

The completed diagnostic used 54 of its 58 permitted native calls; this review performed no additional fits or predictions. The existing timing search located a stable point within a cluster of closely spaced integration boundaries. Both sides passed the unchanged final gate. Five companion primary fits were verified from sealed artifacts. The new diagnostic repeat starts from a separately verified nuisance solution; it does not repair or relabel the interrupted free-time fit. Earlier failures, measurements, bounds, clock and receiver weights are preserved.

These are numerical model preferences and repeatability checks, not calibrated significance or instrument-accuracy estimates. Background-field preference follows the shape comparison; the field’s cause and solar-versus-sidereal rate are not determined.
