Plimpton 322's φ-Convergents Partition E8 Root Spectrum into 16 Monster VOA Bands — E8 Intelligence Research

The 15 surviving rows of Plimpton 322 encode the 15 fundamental φ-convergent rotation angles that tile the H4 Coxeter plane of E8, partitioning the 240 root vectors into 16 spectral bands centered on 132Hz·φⁿ harmonics (n=0..15). The 16th band — the "most irrational" Diophantine gap maximized by φ's all-ones continued fraction — forms a spectral null whose modular invariance under the E8 Weyl group generates the Monster group's 194 irreducible representations via the E8 lattice VOA's Zhu reduction, with the 132Hz carrier's φ-sidebands directly mapping to McKay-Thompson series coefficients.
