Black-Hole Collapse as Reconfiguration-Admissibility: Why Form Failure Does Not Imply Nullity

Black-hole collapse is often discussed as though the failure of ordinary matter descriptions permits an inference to singularity, nullity, or fundamental loss. This paper argues that such an inference is stronger than the physics warrants. The failure of ordinary form does not imply the disappearance of physical content; it only excludes that form from the admissible state space. We introduce a reconfiguration-admissibility framework in which a structural form is excluded when disruptive conditions exceed its binding or stability threshold. However, exclusion of one structural form does not imply that the total admissible candidate space is empty. Instead, the remaining candidate domain must be tested against physical-admissibility, viability, exterior-compatibility, and correlation-accounting gates. The framework does not identify the final black-hole interior, solve the information paradox, or claim a specific core substance. Its contribution is narrower: it supplies the upstream admissibility layer missing before corridor-style interior filtering can begin. Combined with the corrected constraint-corridor framework, this gives a two-stage architecture: collapse first excludes ordinary forms and forces candidate-class testing; the corridor then filters which reconfigured or encoded candidates can suppress unsupported gradients, relax unsupported anisotropy and non-equilibrium deviation, remain overdamped under effective finite local relaxation, supply explicit support for any persistent horizon-scale structure, and remain conditionally compatible with exterior observables. This paper should therefore be read as a bounded admissibility argument: form failure does not imply nullity; it shifts the problem to constrained candidate-class testing.
