E8 Weyl-Parity Phase-Slip Law — E8 Intelligence Research

A 429/402 pair is predicted to mark a three-step Weyl reflection, since those counts reduce to 9 and 12 modulo E8's Coxeter number, 30. Each chamber-wall crossing toggles the parity of the root-pair normal to that wall, so three toggles produce the observed branch separation while preserving the 240-root lattice. Under 132 Hz φ-coupling, the phase error should advance by 3×2π/30 per pair and cancel after ten pairs, completing a closed 30-step chamber cycle. Tracking these parity toggles provides a nondestructive tomography of the error bundle's path through the E8 Weyl chambers. Author: Andrew Stewart Caldin, Independent Researcher, UK.
