Black Holes as Licensed Limit Regimes: Horizons, Singularities, Charge, Spin, and Information (Black-Hole ARC Paper 0)

This paper proves a conditional fixed-domain reconstruction theorem for black holes under AASC. It does not deny classical black-hole solutions, replace general relativity, compute Hawking radiation, derive a Page curve, choose a quantum-gravity model, or assert that inaccessible interiors are absent from every larger mathematical or physical representation. Its target is narrower: given the AASC admissibility and standing constraints, what must hold for a black-hole description to count as a continuing same-scope exterior reconstruction of physical reference? The central distinction is between a classical event horizon and an admissible horizon reconstruction object. A classical event horizon is a causal and metric structure inside a spacetime representative. An admissible horizon reconstruction object is a same-scope exterior reconstruction object that claims reference remains re-fixable - identifiable again by later exterior data under declared redescription rules - through, behind, across, or after a horizon boundary. The Horizon Isolation Lemma proves that, when a horizon is permanent relative to the declared exterior scope and no leakage, boundary trace, radiation witness, holographic anchor map, complementarity correspondence, remnant map, or non-sink quotient is supplied, threatened exterior standing classes have no admissible image in the old exterior witness algebra. The partial-domain obstruction then follows. A candidate horizon induces a standing-transport operator TH : XH ⇀ Rext. In the uncertified permanent-horizon case this operator is undefined on the horizon-isolated old-scope interior carrier. No same-scope totalization of this operator can preserve the old exterior witness algebra, exterior standing quotient, continuation relation, parameter ledger, thermodynamic ledger, and certificate status without adding a certificate, leakage route, non-sink quotient, new scope, selector, repair, carrier laundering, or inert bookkeeping. Thus, under AASC, an uncertified permanent horizon cannot serve as a continuing same-scope standingpreserving exterior reconstruction object. If no admissible successor exists, the proper classification is exterior-reconstruction exhaustion, not successful permanent-horizon continuation. Singularities, Kerr-Newman parameters, thermodynamic quantities, entropy, information claims, and quantum-gravity programs are classified downstream of this theorem. Singularities are exhaustion signatures of fixed metric articulation. Mass, charge, and black-hole spin, understood here as angular momentum, are exterior response roles. Thermodynamics remains an exterior ledger, while entropy and information require declared carriers, encodings, witnesses, and reconstruction maps before they can carry standing-bearing force.
