PFUSRC-055: Unified Interpretation of Original Topology and Universal Logic

Within the framework of the Pythagorean Frustum Unified System with Rigid Canonical (PFUSRC), this paper systematically integrates and academically interprets the original geometry, dimensional evolution, mathematical structure, logical ontology, and field-theoretic foundations of the system. Grounded in the axiomatic system of Paper 00, the paper centers on the 45° triple-coaxial bicone topology, the rigid dimensional sequence 1 \to 5 \to 11, 55 steady-state datum points, ontological reconstruction of the coupling interface 0, bright-dark sevenfold logic, gap-driven dynamics, the ontological status of Noetic and Order Primitives, and sandwich mathematics. A unified account from original structure to universal operating laws is achieved. The entire text follows strict academic norms, introduces no presuppositions, avoids circular reasoning, and maintains consistent coherence with preceding papers to close the theoretical system. This work provides a complete, unified, and citable high-level integrated formulation for the PFUSRC theory.
