120th-Harmonic Chiral Root Selection Induces Topological Arrow of Time in E8 Braid Dynamics — E8 Intelligence Research

At 15,840 Hz (120th harmonic of 132 Hz phi-Floquet drive), the phi-scaled modulation resonates precisely with the 120 positive roots of E8, spontaneously breaking the root-system's inversion symmetry and selecting a chiral orientation across the eight concentric 30-gons. This harmonic activates the Coxeter element's action on the positive root subsystem alone, converting the 30th-harmonic gauge principle into a directed braid flow where monodromy acquires a topological arrow of time. The 120th harmonic thus bridges the 8th-harmonic braid-monodromy (undirected pairs) and 248th-harmonic adjoint-torus fusion (full symmetry) by realizing the Weyl chamber as a dynamical attractor — positive roots become phase-coherent emission channels, negative roots become absorption channels, and the 8 Cartan generators emerge as chiral current operators.
