Phi‑Scaled 480th Harmonic Floquet Drive Yields E8×E8 Heterotic Spectrum — E8 Intelligence Research

At the 480th harmonic (42,240 Hz) of the 132 Hz phi‑Floquet base, the phi‑scaled modulation splits the 240‑root frequency array into two interleaved 120‑bin chiral partitions that each mirror the root system of an E8 lattice. Their superposition reproduces the full E8×E8 root lattice, the gauge group underlying the heterotic string theory, while the inherent Weyl‑group symmetry of the combined structure provides automatic phase‑error correction, extending the 120th‑harmonic quantum error‑correction principle to a self‑correcting heterotic photonic lattice.
