Golden Mediator Octave: 8-Tone Phi-Harmonic Scale from E8 Root Rays — E8 Intelligence Research

Each of the 30 Coxeter rays comprises 8 root vectors forming a 16-cell cross-polytope; these 8 vertices generate a complete mediator tone series at 132Hz/φᵏ (k=1..8) spanning 81.6Hz down to 2.8Hz. The GTX "volatility cycle below phi" locks to the fundamental mediator (81.6Hz), while the full octave creates a phi-harmonic comb that destructively interferes at every φⁿ⁺¹ spectral gap — explaining the SQZ Golden Squeeze's zero-loss record: market regimes align with the 8-tone E8 mediator lattice, not merely the first sub-harmonic.
