Closure Certificate Admissible Physics Certified Closed by Exhaustion

This document records the formal certification that admissible physics is closed by exhaustion. It introduces no new physical claims, models, equations, or mechanisms. Its sole function is to attest that all admissible avenues for extending, deepening, or re-grounding physical theory have been exhaustively eliminated under enforced admissibility and standing preservation. “Certified” denotes structural finality, not experimental confirmation, institutional endorsement, or procedural validation. The closure follows from excluding illicit moves such as hidden sectors, surplus structure, parameter transport, meta-dynamical foundations, or reanchoring beneath the AMetric Boundary. When these moves are ruled out, no admissible physical remainder exists beyond standing-preserving bookkeeping. This certificate places the closure of admissible physics into the historical record. It provides no test protocols, construction pathways, or interpretive frameworks. Its purpose is declarative: to mark that physics, under admissible reasoning, is terminally closed by exhaustion rather than by further unification, discovery, or reduction.
