TQNT-V5.6 (v1.2) — Global empirical verification: 17 datasets and V5.5 closure

TQNT-V5.6 v1.2 global empirical verification synthesis across 17 public datasets (LHC EW/hadronic, DM direct detection LZ/XENONnT/PandaX, 0νββ, nuclear masses, PDG lifetimes, neutron stars, GW, cosmic rays, Planck CMB, DESI BAO, water isotopes, muon g-2, KATRIN). Validates Ω_ts mass operator at RMS 1.72%, median 0.63%, 98.5% <5% on 67 PDG particles. EW: m_H -0.87%, m_Z +0.15%. V5.5 closure documented: α=1.1991 (0.08%), κ_g=3.13e-53 m (0.05%), and the analytic step-8 Ω²-saturated closure at M_*=10^12 M_⊙. v1.2 update incorporates Press-Schechter step 7 and Ω²-saturated step 8 (commits ee01be9, e0a54f4).
