USP Field Theory — Symmetric Fusion Suite (msf:45683)

This document unifies the Symmetric Fusion Rules (RQM1) and Fusion Simulation Report into a single, calibrated framework aligned with USP Field Theory msf:45683 — Fusion via Δf Compression.It introduces a quantitative Δf-based model of nuclear fusion as a resonant field compression process, replacing the traditional kinetic-collision narrative with a spin-tension and geometric coherence mechanism. Part I establishes the geometric closure law: > (Equation 1) Eₘᵢₛ = kσ²(Equation 2) K = exp [ − (σ / σ_c)² ] and connects it to the field-driven relation: > (Equation 3) Δf_local = Δf₀ + αP + β (T − T₀) with solar-scale calibrations: > Δf₀ ≈ 10¹⁸ Hz α ≈ 10⁷ Hz / Pa β ≈ 10⁶ Hz / K Fusion feasibility arises when > (Equation 4) Δf_local ≥ Δf_crit ≈ 10¹⁹ Hz, K ≥ 0.9 corresponding to solar-core conditions(P ≈ 1.6 × 10¹⁶ Pa, T ≈ 1.5 × 10⁷ K). Part II extends these rules into simulation space, mapping feasible domains and interpreting photon emission (~ 0.1 MeV per event at 10¹⁹ Hz) as Δf-loop collapse.The study also includes a theoretical discussion of field-boundary tension (T_f ≈ 10⁻³⁴ N m⁻²) and symmetry effects (C₃ photonic-cavity analogs). All content remains theoretical and non-actionable, focusing on the mathematical, geometric, and field-resonant interpretation of fusion.This v2 release replaces earlier uncalibrated RQM1 and simulation documents, providing a unified, numerically anchored model suitable for archival reference and safe academic citation.
