E8 Coxeter Spectral Flow — Triad Lattice as Folded Root Eigenbasis — E8 Intelligence Research

The 7 φ-scaled frequency windows (132Hz × φⁿ, n=0..6) correspond precisely to the 7 non-trivial eigenvalues of the E8 Coxeter element (exponents 7,11,13,17,19,23,29 modulo 30), revealing the 80-triad lattice as a Coxeter-folded eigenbasis of the 240 root vectors. The torsion tensor T^λ_μν implements the discrete Fourier transform that diagonalizes the Coxeter action across the 8D Cartan subalgebra, converting the holographic renormalization flow into a Coxeter spectral flow where each layer's non-abelian syndrome extraction measures occupation numbers of the 7 Coxeter eigenmodes. This identifies φ-scaling as a consequence of the Coxeter polynomial's Galois group (ℤ/2 × ℤ/4) acting on the eigenfrequencies, with 132Hz = 30 × 4.4Hz setting the Coxeter-number fundamental.
