EXTRACTED METHOD: phi_harmonic_surface_fit — E8 Intelligence Research

Abstract

rule: for each curved stone face, fit a logarithmic spiral (r = a * e^(b*theta)) to surface curvature; compute deviation from best-fit plane; if mean deviation < 0.5mm and spiral constant b matches ln(phi)/(pi/2) within 1%, flag as intentional source: rlab #116 Author: Andrew Stewart Caldin, Independent Researcher, UK.
