Central-Theorem constraint on physical loci

A hom-object locus becomes a candidate physical site only if its boundary and interior data satisfy the mutual-determination discipline of the Central Theorem. The iota_tau-calibration channel transports boundary spectral data into the holomorphic interior, so localization is not a free label placed on a morphism. A physical locus is admitted only when boundary character, interior ω-germ, and spectral data cohere through the calibrated bulk – boundary isomorphism.
