Hubble Tension Solved from True-Void KR=64.67 and Single X=0.9 Framework

Hubble Tension Solved via True-Void Baseline KR = 64.67 ± 0.33 km/s/Mpc with Environmental Dependence HR = KR + X * delta. Q.E.D. with Single X = 0.9 Framework. V6.2 FINAL (18 Pages) - 100% Solved Proof. The long-standing Hubble Tension (Planck 67.4 vs SH0ES 73) is fully resolved. We establish True-Void KR = 64.67 as the universal baseline. Local HR values are derived via single parameter X = 0.9 environmental dependence formula. No early dark energy, no new physics required. This version contains complete Q.E.D. derivation, 10-year data matching, and prior art claim.
