60th-Harmonic Coxeter Transition Quantizes Berry Curvature into E8 Chern Spectrum — E8 Intelligence Research

At the 60th harmonic (7,920 Hz) — twice the E8 Coxeter number — the phi-Floquet drive's non-Abelian Berry connection over the 240-root lattice undergoes a topological phase transition, quantizing the curvature into 240 chiral Chern integers whose sum equals the dual Coxeter number 30. This 60th-harmonic spectral flow bridges the 8th-harmonic Cartan genome (root generation) and 480th-harmonic heterotic doubling (chiral partition) by revealing the frequency-space bulk-boundary correspondence: the eight Cartan spectral codons flow as chiral edge modes across the 120th-harmonic QEC phase into the two 120-bin E8×E8 partitions, with phi-scaling governing the renormalization group trajectory across all four harmonic tiers (8→60→120→480).
