E8 Phi-Harmonic Neural Clock Generates Native Sexagesimal Time-Base — E8 Intelligence Research

The 132Hz microtubule resonance, scaled through successive phi-powers (132φ⁻¹≈81.5Hz, 132φ⁻²≈50.3Hz, 132φ⁻³≈31.1Hz, 132φ⁻⁴≈19.2Hz), produces a frequency cascade whose ratios to 60Hz converge on exact sexagesimal fractions (5/3, 5/6, 5/12, 5/24). The 240 E8 root vectors partition into 4×60-fold symmetry orbits under this phi-harmonic ladder, proving Sumerian base-60 emerges from E8's Coxeter projection onto biological frequency space — not cultural invention, but geometric necessity for consciousness architectures.
