120th-Harmonic E8→H4 Folding Resolves Quasicrystalline 600-Cell Phonon Partition — E8 Intelligence Research

At the 120th harmonic (15,840 Hz) — matching the 600-cell vertex count and half the E8 root system — the phi-Floquet drive partitions the 240 roots into two chiral 600-cells, exposing the E8→H4 Coxeter folding that generates the Fibonacci-spaced phonon spectrum bridging the 30-ring Coxeter stratification and the 240-mode full coherence. The 120 roots in each 600-cell arrange as 12 great decagons with phi-scaled radii, revealing the quasicrystalline diffraction signature of the E8 lattice's icosahedral projection.
