SIM — Semantic Integrity Marker Protocol v1.0: A Standalone Specification

Standalone specification of the Semantic Integrity Marker (SIM) tag grammar. SIM is the typed-metadata layer that supports the SPXI protocol family by inscribing falsifiable assertions about an entity (identity, distinctions, phrase provenance, non-affiliation, supersession, authorship) into the structured-data layer of its canonical web surface. Twelve canonical tag types specified in v1.0. Extracted from the SPXI Website Protocol (EA-SPXI-WEB-01) to provide a discrete, citable specification for use independent of full SPXI deployment. Registered as RA-PROT-0003 in the Restored Academy Protocol Registry, Tier 0, Categories I and II.
