Rigid Global Isomorphism between PFUSRC and 2025–2026 Frontier Experimental Observations

This paper establishes rigid, parameter‑free, one‑to‑one global isomorphism between the PFUSRC (Pythagorean Frustum Unified System – Rigid Canonical) theoretical framework and seven high‑precision frontier experiments observed during 2025–2026. All experiments are published in Nature, Science, and Physical Review Letters, covering high‑energy physics, condensed matter physics, quantum information, astrophysics, and cosmology. Each observation is proved to be structurally consistent with the 45° triple coaxial biconic geometry, the unique dimensional evolution sequence 1\Rightarrow5\Rightarrow11, prime topological reference points, 55 global steady‑state datum points, and the 12:11 universal gauge invariance derived in PFUSRC‑00 and PFUSRC‑51. No ad hoc assumptions, free parameters, or artificial corrections are introduced. This work confirms that PFUSRC is the unique fundamental ontological structure capable of unifying all modern experimental observations within a single self‑consistent topological system.
