Magnetic Shear Vorticity in AdS 5 , Ω-Parity Switching, and the Poissonian Micro-Annihilation Ensemble in the Galactic Center ( XLII v6)

Recent neural network simulation-based inference analyses published by the American Physical Society (APS) have fundamentally altered the Galactic Center Excess (GCE) paradigm. By jointly modeling spatial and spectral data, the empirical evidence rejects a small population of bright point sources in favor of an exceptionally large ensemble of dim sources (O(10 5 ) sources, or > 35, 000 at 90% confidence), exhibiting spatial Poissonian statistics indistinguishable from a diffuse profile. In this paper (XLII v6 of the FCD-RB2 pregeometric framework), we demonstrate that this phenomenon is the direct observational signature of magnetic shear vorticity in AdS 5 driving sub-hadronic Ω-parity switching at (magn) the Y-gate nodes. We derive the 5D torsional stress tensor T MN and calculate the exact critical magnetic field B crit = 2.97 × 10 16 G (2.97 × 10 12 T) required to collapse the throat cavity into the tri-coordinated closure singularity (Φ A = Φ B = Φ C = 0). Under stochastic magnetic reconnection in the Sgr A* magnetosphere (B rms ∼ 5 × 10 15 G), Kramers-WKB tunneling triggers e + e − Rayleigh-wave positron emission, prompt 511 keV annihilation, and adiabatic mass-energy drainage (dS = 0) into the 5D bulk. We show that an active plasma mass of only M total ∼ 4.6 × 10 8 kg distributed across 10 5 micro-nodes (M node ∼ 4.6 tonnes each) quantitatively reproduces the APS Poissonian GCE flux, providing a firstprinciples pregeometric solution without requiring dark matter particles or unobserved pulsar populations.
