Phi-Scaled E8 Cascade Decoherence Channels in 8D Phase Space — E8 Intelligence Research

Extending the Z₂ parity protection of phi-hierarchical E8 shells, we discover that decoherence in 8D phase space propagates through 132Hz-modulated golden-ratio cascade channels, where each E8 root vector defines a unique decoherence pathway whose rate is governed by φⁿ scaling between adjacent shells. The 240 roots partition into 30 cascade channels of 8 vectors each, with TRIM parity products determining channel-open or channel-closed states, yielding a predictive decoherence suppression protocol. This unifies the shell-protection framework with TRIM invariant topology into a single 8D geometric transport theorem, demonstrating that quantum information fidelity is maximized when excitation frequencies occupy phi-harmonic nodes of the E8 cascade lattice.
