Diagnostic geometry only: no location identity, probability, statistical confidence, surveying accuracy, legal boundary, or geofence suitability is established. Entered interpretation labels are preserved without statistical conversion.

Assumptions
- Sphere radius: 6,371,008.8 m.
- Circle pairs use great-circle center distance and entered radii exactly.
- Boxes use a local east/north tangent plane and rotated separating-axis test; mixed pairs use closest point to the rotated rectangle.
- “Definitely separate” is only under this model; other labels never assert same location or probability.
Box approximations are warned above 100 km center range or 75° absolute latitude.
