Derives all five Standard Model constants simultaneously from ρ_s with zero additional free parameters: α_em (0.05%), α_s (1.8%), sin²θ_W (0.01%), m_W (0.015%), m_Z (0.7%). Also derives ħ (0.136%), the proton charge radius via back-calculation (0.19%), and the Koide mass scale M₀² = 313.97 MeV (0.042%). Predicts five new resonances at 26.88, 85.61, 108.19, 117.84, and 139.62 GeV.
