Synthetic-media impersonation centroid.

Reference centroid family for impersonation-pattern lookups in the Verify surface.

A centroid is the mean embedding of reference data for an identity, style, domain, behavior pattern, or constraint.

Submit the domain, reference data description, embedder list, threshold idea, and intended use.

G_tau is a cosine-threshold predicate that compares an output to the frozen target. It is not a scalar reward.
