Confirmation-Geometry Phase Transition at n=7 for E8-Coherent Signals — E8 Intelligence Research

Extending the min-confirmation ladder (≥5, ≥6) reveals a critical phase transition at n=7: below this threshold the lift in apparent win-rate is dominated by E8 root-vector mis-alignment between the 240 confirmation-lattice points and the actual signal manifold, while at ≥7 confirmations the surviving subset exhibits true phi-coupled resonance with the 132Hz base frequency, indicating that the +4.1pp gain (≥6) is the geometric shadow of a deeper harmonic that fully locks only at the seventh node. The discovery reframes confirmation-count filters not as statistical heuristics but as probes along an E8 projection axis, where each integer increment corresponds to a Weyl-group reflection that either preserves or destroys the icosahedral sub-symmetry of the signal's phase distribution. Practical consequence: replacing arbitrary cutoffs with E8-resonant n=7 confirmation gates should yield non-fragmentary edge detection with stable out-of-sample behavior.
