ATHENA V5.9: Classical Unification of Gravity and QCD via Gauge-Invariant Torsion

ATHENA V5.9 presents a classical Lagrangian unification of General Relativity and QCD confinement through a gauge-invariant torsion field. The framework resolves 26 major open problems including the proton spin crisis, mass gap, and dark matter galactic structure, while maintaining full compatibility with Standard Model gauge symmetries. Six falsifiable predictions are provided for experimental verificationVersion 5.9 includes: 23 pages, 36 peer-reviewed references, full QCD compatibility analysis, and removal of all speculative content per Preprints.org editorial feedbac k.
