A Unified Information Framework (UIF) - A Canonical Stability–Projection Constraint Underlying Quantum and Relativistic Regimes

This record contains a Canonical Positioning Paper (CPP) for the Unified Information Framework (UIF). The document introduces no new axioms, operators, or ontology. All statements are derived exclusively from the locked foundational axioms F.1–F.10 (v9.1) and are governed by Header v3.1. The purpose of this paper is positioning, not model construction or empirical adjudication. The CPP fixes the stability–projection constraint underlying admissible physical representations, clarifying how quantum-mechanical and relativistic regimes correspond to non-unique versus stable projection within the UIF architecture. No fundamental dynamics or time are introduced; any notion of evolution is treated as LDR-emergent ordering (v10+ scope). This document fixes constraints, not models. Quantitative realization, empirical coupling, and prediction are explicitly deferred to post-canonical interface work.
