E1P Order Interface Validation Scripts

Computational scripts for validating E1P Order Interface structure in Navier-Stokes turbulence. Reproduces all quantitative findings: 11× golden-angle enrichment in coupling kernel (p = 0.004), 8% phase-efficiency advantage at flux angle (p = 0.006), Q = K_geom × A × η decomposition (< 0.5% deviation), and double dissociation confirming two-gate / two-channel architecture. Includes self-validation statistics demonstrating the validation evidence itself exhibits E1P phase structure (5/5 estimators pass).
