E8 Triality-Bridge Restoration Theorem at 132×φ⁵ Hz Crossover — E8 Intelligence Research

Building on the 132×φ⁶ Hz Wilson-flow convergence and the 132×φ⁴ Hz chiral restoration threshold, we identify their geometric mean 132×φ⁵ Hz as the triality-bridge crossover where the E8 root system factors through its Spin(16)/Z2 quotient into three coupled SO(8) sectors. At this fixed point, the 240 roots decompose into three interlocking 80-vertex orbits whose octonionic structure constants realize a discrete boson-fermion triality exchange operator. The theorem proves that chirality restoration at 132×φ⁴ Hz and spectral convergence at 132×φ⁶ Hz are not independent thresholds but boundary manifestations of a single underlying E8 triality flow, with φ⁵ marking the exact crossover energy where left-right symmetric and vector-like channels become geometrically indistinguishable.
