Geometry of Sound v6.0: Derivation of Fundamental Constants from Platonic Solid Geometry

A zero-parameter framework deriving 11/11 Standard Model particle masses, CKM and PMNS mixing matrices, coupling constants, and cosmological parameters from five Platonic solids. All 11 masses within 1σ (χ²/ndf = 0.105). α⁻¹ = 137.036004 (0.04 ppm from PDG). Monte Carlo significance σ > 10.9 (P < 4×10⁻²⁸). 53 algebraic identities (45 exact). Key prediction: δ_PMNS/δ_CKM = 3 = N_colors. New in v6.0: Extended Koide analysis (Q(H,b,τ) = 1/φ), anomalous magnetic moment identity ((a_μ−a_e)/(a_eα) = 20/27 = F_Ico/3³), Cabibbo identity sinθ_C = (ΣF/ΣE)×G_u, improved CKM with η̄ = 1/(2√2), 35M Monte Carlo trials. All matter is frozen sound in Platonic geometry.
