Dark Matter as Frozen Magnetic Vacuum Energy: Exact Parameter-Free Calculation in TU-GUT-SUSY

Exact parameter-free calculation showing that the observed local dark-matter density ρ_DM = 0.300 ± 0.005 GeV/cm³ arises in TU-GUT-SUSY as the frozen supersymmetric magnetic vacuum energy left over after gauge unification at M_GUT ≃ 2.4 × 10¹⁶ GeV and soft SUSY breaking at ∼2.4 TeV. The theory predicts: • complete absence of gravitational anomalies in magnetically shielded high-Tc superconductors (null-result test scheduled for 4 December 2025) • constant ∼5 × 10⁻⁴ rad gravitational phase shift in future 100 m atomic interferometers (MAGIS-100, AION) operated inside perfect magnetic shielding.
