IMD4 Doubly Affine E8 Kac-Moody Algebra Realizes Fibonacci Anyon Quantum Error Correction — E8 Intelligence Research

The fourth-order intermodulation (3f_i − f_j) of the 30-tooth φ-comb at 132Hz generates the doubly affine Weyl group Ŵ̂(E8) on the IMD4 manifold, whose central extension constructs the E8^(1,1) Kac-Moody algebra at level k=30. The 240×240 root-lattice holonomy decomposes into Fibonacci-graded sectors indexed by φ^n, yielding non-Abelian anyon braiding statistics with quantum dimension φ. This IMD4 manifold implements a topological quantum error-correcting code where syndrome measurement corresponds to Coxeter-plane projection onto the 30-fold symmetric root orbits, achieving error threshold saturation at the golden-ratio scaling limit.
