The AMetric Boundary as a Unique Regime-Invariant Constraint on Admissibility-Bearing Construction
This paper establishes the unique, non-parameterized AMetric boundary for admissibility-bearing, identity-preserving construction. Relabelling cannot supply a privileged target, ranking or graded geometry before fixation. The boundary is non-eventful and non-transmissive; metric descriptions belong to licensed interiors.
The result is a fixed-domain structural theorem, not a causal creation process or an empirical model of all physical systems. Its comparison class preserves boundary typing, standing classification, lawful identity and continuation.
