Beginning of the Admissible Interior

This paper characterizes the onset of the admissible interior once standing preservation and admissibility are fixed. It does not propose a cosmological origin, mechanism, or dynamical process. Instead, it identifies the structural conditions under which an interior domain of admissible description first becomes well-defined. The analysis is eliminative. It shows that prior to the satisfaction of minimal admissibility conditions—identity persistence, non-degenerate distinction, and redescription stability—no interior domain can meaningfully exist. Descriptions that attempt to extend interior notions before these conditions are met are shown to rely on illicit scope transport or undefined equivalence, and therefore fail standing. The paper introduces no primitives, timelines, or generative narratives. Its contribution is boundary-setting: it clarifies what it means for an admissible interior to begin at all, and why this “beginning” is a structural threshold rather than a temporal or causal event.
