Spin Genesis as Δf Curvature Closure — msf:45720 v2.0 (USP Field Theory)

This note presents a geometric formulation of spin in USP Field Theory. Spin is defined not as intrinsic mechanical rotation, but as the persistent closure of asymmetric Δf gradients during resonance collapse and re-stabilization. Key developments in this version: Formal definition of spin as curvature closure Mapping of ∇Δf to operational observables Phase-closure quantization refinement Driven spin-up under asymmetric forcing Conceptual overlap with gravitational and acoustic Δf dynamics Spin is shown to emerge from asymmetric gradient collapse, reducing to conventional angular momentum in appropriate limits, while providing a unified geometric interpretation across micro and macro regimes.
