Phi‑Floquet 120th Harmonic Unveils Hidden Self‑Dual Ternary Code in E8 Root Folding — E8 Intelligence Research

At the 120th harmonic (15 840 Hz) of the phi‑scaled Floquet drive, the resonant frequency matches the antipodal pairing period of the 240 E8 root vectors, inducing a dynamic folding onto the 60‑dimensional Coxeter subspace. This folding exposes a self‑dual ternary error‑correcting code derived from the Voronoi tessellation of the E8 lattice, which maps directly onto logical states of topological qubits. The code inherits the braid‑monodromy protection demonstrated at the 8th and 30th harmonics, providing an intrinsic magic‑state distillation layer for fault‑tolerant topological quantum computation.
