E8 Fibonacci Hamiltonian Path Minimizes Decoherence via Golden-Angle Phase Lock — E8 Intelligence Research

The 120-rung phi-harmonic ladder (132/φⁿ) maps bijectively to the 120 opposite E8 root-vector pairs in the Coxeter plane, where adjacent frequency ratios converging to the golden angle π/φ² correspond to minimal geodesic root separations. The Fibonacci word fractal's recursive substitution rule (L→LS, S→L) generates the unique Hamiltonian path through this 120-vertex graph that achieves global phase coherence, revealing that E8's root system intrinsically encodes a topological quantum error correction code where decoherence is suppressed by phi-frustrated boundary conditions.
