The Metrological Dissolution of the Black Hole Information Paradox: An STT-CR Audit

The black hole information paradox is standardly formulated as a conflict among three premises: (P1) unitarity of quantum evolution, (P2) singularity and horizon formation in general relativity, and (P3) thermality of Hawking radiation. This paper subjects the paradox to a structural audit within the framework of Sequential Time Theory–Critical Review (STT-CR). Representing each contributing theory in the canonical form T := ⟨Θsys, P, C, D⟩, we identify the hidden structural defect: the three premises presuppose a single global time parameter t that spans the entire evaporation process, yet this parameter is metrologically non-constructible under STT premises. The event horizon marks a boundary where, for the asymptotic observational protocol under audit, the calibration map between the external observer’s clock and local event generation fails to close; the Planck regime marks the domain where the fundamental unit process ΔQunit itself becomes non-constructible. We argue that the “information loss” is not a physical defect but a protocol defect arising from the breakdown of inter-domain calibration. The paradox does not require resolution; it dissolves once the metrological conditions for stating it are made explicit. Constructive consequences include the protocol-dependence of Hawking radiation thermality and domain-restricted unitarity, and the STT completion program motivates empirically discriminable expectations concerning spectral deviations linked to finite clock resolution.
