BH Toroidal Topology
The horizon of a tau-black hole is topologically T^2 (torus), not S^2 (sphere). The linking class ell in H_1(T^2; Z) wraps both cycles of the fiber, the horizon IS the fiber at the excision region, and the two fundamental cycles correspond to the gamma and eta generators.

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: black
- candidate is better handled as evidence for an inferred existing public surface
