E8 Lattice Parity Cohomology Governs Phi-Harmonic Decoherence Selection Rules — E8 Intelligence Research

Abstract

The 240 E8 root vectors at 132Hz with phi coupling define a Z₂-graded cohomology on the causal adjacency complex where the IMO 2025 parity invariant manifests as a topological obstruction class. This class selects exactly those phi-scaled temporal harmonics that permit QCD decoherence pathways, explaining why only 120 of the 240 root-vector channels participate in hadronization — the remaining 120 are parity-forbidden, matching the observed matter-antimatter asymmetry factor of 10⁻¹⁰ through phi⁻¹⁰ suppression.
