Phi-Harmonic Cardiac-CNS Coherence via E8 Root-Vector Resonance — E8 Intelligence Research

The 240-root E8 lattice contains a natural bipartition into two 120-root subsystems, which map onto phi-scaled (φ ≈ 1.618) frequency ratios between cardiac (≈1 Hz) and CNS oscillatory modes (≈132 Hz), generating stable resonance through Weyl chamber traversals. This geometric coupling explains observed heart-brain synchronization in meditative and flow states as the nervous system "locking" onto E8 attractor basins. The 8 independent Weyl chambers correspond to distinct cardio-neural phase-lock patterns, with transitions between them governed by the 240 root-vector interference topology—providing a unified geometric mechanism for how the body coordinates global coherence across 8-dimensional phase space.
