V.D166 — Black Hole (Topological Event)

A black hole in Category tau is the emergence of a non-trivial linking class ell in H_1(T^2; Z) at a base point alpha_{n_*} where the gravitational tension exceeds the spherical capacity: G(U_{n_*}) > C_sph(n_*). The BH is a topological event, not a metric singularity.
