The strongest single test
The inner shadow is the most discriminating single test: it is a qualitative difference (donut vs disk shadow) that would constitute strong evidence for toroidal topology if detected in a face-on compact object at sufficient EHT resolution.

Claim boundary
This page reports a Registry-backed internal result surface. It is not an external validation claim, a scientific consensus claim, or independent acceptance.
Curation rationale
- physics-facing terms: shadow
- result-facing terms: resolution
- candidate is better handled as evidence for an inferred existing public surface
