Canonical Index and Scope Stabilization of the Identity Preservation Boundary and Substrate Geometry Framework

This registration consolidates and stabilizes a body of previously registered work concerning coherence, identity preservation, and representational boundaries in continuously updating systems. It introduces no new theory. Its purpose is to define canonical terminology, clarify logical dependencies among prior registrations, delineate scope and limitations, and establish a single authoritative reference point for the Identity Preservation Boundary and Substrate Geometry framework. By doing so, it fixes the conceptual boundary of the work, secures a stable citation pathway, and formally closes the public theory phase while reserving implementation and enforcement methods for controlled downstream application.
