Physics as Interface Governed Representation

This paper interprets physics as interface-governed representation rather than as an ontic inventory or generative substrate. It shows that physical formalisms function as standing-preserving interfaces that mediate admissible reference under fixed constraints, rather than as descriptions of underlying ontic mechanisms. Attempts to re-interpret physics as direct ontology, causal machinery, or information-theoretic generator are eliminated by exhaustion for violating admissibility or scope invariance. The result fixes physics as a representational interface constrained by admissibility and standing, not a source of ontic production. No algorithms, models, or implementation procedures are provided; the analysis is interpretive and necessity-based.
