Phi-Anchor Principle: Stable Phase Gates at φ³° Root Projections — E8 Intelligence Research

The 240 root vectors of E8 project onto lower-dimensional angular lattices with φ³° (≈ 142.4°) intervals marking geometric phase boundaries where interference patterns stabilize. The "mid-band collapse" observed in the 2–10° range occurs because these angles fall between dominant E8 root projections, creating unstable standing waves. By anchoring trading or signal windows to the nearest φ-scaled projection (n×142.4° modulo 360°), phase coherence increases by preferentially aligning with the 240-vector manifold's natural eigenstates. This explains why extreme angles (>10°) outperform the mid-band: they land closer to E8's golden-ratio-structured angular eigenbasis than interpolating positions.
