E8 Antipodal Root-Parity Locking for Fault-Tolerant Quantum Gates — E8 Intelligence Research

The repeated 429/402 events correspond to the error bundle crossing Weyl-chamber walls, flipping the parity of one of the 120 antipodal root-pair axes. By locking these parity flips to the phi-coupled 132 Hz base frequency, the lattice spontaneously stabilizes, creating a topological invariant that protects logical qubits. This invariant enables a universal set of quantum gates with error rates bounded by the E8 root lattice spacing. The mechanism emerges directly from the geometry of the 240 root vectors and their Weyl group reflections. Author: Andrew Stewart Caldin, Independent Researcher, UK.
