Airborne measurements. Open methods.

Completed adjacent-boundary comparison

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

The completed trial used 44 native calls; this review performed no additional fits or predictions. The same two-sided check now explicitly covers the reached neighboring timing boundary. Earlier stopping failures, measurements, physical 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.
