ABSTRACT This paper proposes and develops the Unitary Reference Principle (URP), a foundational reform of quantitative mathematics built on a single structural claim: every meaningful quantity is a fraction of a declared reference R, and no value within a declared frame exceeds 1. The framework is developed across three axiom-driven steps — Step 0 (declare R), Step 1 (calculate), Step 2 (verify) — and applied to arithmetic, division, zero, negative numbers, the unsolved Millennium Problems, and the physical world. This third edition adds the surplus framework, extending the URP domain model from three structural states to five. The complete domain now comprises: COMPLETE (n/R = 1), PARTIAL (0 1 — triggers a new declared reference), and DEFICIT (n/R < 0 — obligation beyond the frame). Surplus mechanics are developed across five new sections (1.5a–1.5e), including the apple-shipment example (251 apples against a declared R of 250), three structural readings of surplus, three physical system responses (overflow into new frame, regulation back to R, frame break), and the complete boundary structure of the URP domain. The second edition incorporated findings from four companion papers: Division Under the URP (Brogley, 2026b), the Riemann Hypothesis Under the URP (Brogley, 2026c), Geometry Under the URP (Brogley, 2026d), and Physical Reality Under the URP (Brogley, 2026e). The Riemann Hypothesis status was upgraded from reframing to structural proof in that edition. The five axioms — Supremacy of Unity, Declared Denominator, Infinite Fractional Domain, Non-Existence of Zero, and Deficit Nature of Negatives — are unchanged across all three editions.
