Sector Paper XXV — The δI Substrate and the Unified Recovery of All Physics

Sector Paper XXV delivers the full structural recovery of all major physics domains from the δI‑substrate, completing the emergence chain of UN Theory. Using only public‑safe correlation geometry, alignment‑mode structure, horizon dynamics, collapse‑energy operators, and ξ‑field cosmology, this paper reconstructs General Relativity, Quantum Mechanics, Quantum Field Theory, the Standard Model, QCD, Electroweak Theory, tensor/high‑density bosonic sectors, cosmology, thermodynamics, classical mechanics, electromagnetism, fluid dynamics, condensed matter physics, nuclear physics, and plasma physics as forced consequences of δI‑geometry. Sector XXV establishes the δI‑substrate as the single generative structure underlying all known physical behaviour, demonstrating that spacetime, fields, particles, forces, and matter‑state physics arise from correlation‑driven limits of the substrate. This document serves as the global recovery map for the public corpus and provides the formal closure of the UN Theory programme.
