Constitutional Legends

Constitutional Legends: Jurisdictional Projection Systems for Governed Semantic Participation introduces a formal semantic architecture in which meaning is governed not merely by lexical surfaces or statistical proximity, but by explicit projection jurisdictions. The paper defines the Constitutional Legend as an authority-bearing semantic projection regime governing admissible semantic participation under declared continuity constraints. The work formalizes: Canonical Semantic Identity Layers (CSIL), Semantic Topology Graphs (STG), legend-relative projection functions, admissible semantic continuity, projection validity, and governed semantic transport. The paper argues that semantic identity, semantic topology, rendering, transport, projection governance, and interpretive authority should be separated into independently governable layers. It further proposes that semantic validity is not determined solely by coherence or usefulness, but by whether a projection remains admissible under its governing legend. Constitutional Legends reframes semantic systems, language interfaces, symbolic compression systems, and AI projection architectures as governed semantic participation systems. The result is a framework for auditable semantic transport, jurisdictional model migration, cross-language continuity, and authority-bearing semantic interoperability.
