Unified Primitive Theory (UPT)

The Unified Primitive Theory (UPT) introduces a new ontological foundation for physics by replacing curvature‑first formulations with a single structural primitive and four projection operators that define energy, mass, curvature response, and gravitational projection as distinct modes of one underlying object. The theory establishes a domain‑torsion relation that governs structural asymmetry and recovers General Relativity strictly as a rest‑frame constraint where . Outside that regime, UPT cleanly separates mass and energy as independent structural projections rather than proportional quantities. This paper presents the full axiomatic architecture, the projection framework, the domain structure, the unified identity, and the GR‑limit recovery, forming a complete and self‑contained field definition
