Gardiner-Gemini Framework (GGF) v2.3: A Near-Critical Superfluid Substrate Model with BCC 14-Contact Polydisperse Topological Knots and Six Pre-Registered Falsifiable Predictions

Version 2.3 of the Gardiner-Gemini Framework (GGF) — continuum-mechanics model of vacuum as near-critical Landau two-fluid superfluid substrate. Fixes v2.0 dimensional errors: kappa_geo=1/4π dimensionless, G_gardiner=G_N/kappa_geo, r_min=G_N rho0 m/(kappa_geo DeltaP) ~1e-35 Pa at 2000 km. BCC 14-contact: 6 cardinals + 8 diagonals, Gamma_14=2A1g+Eg+A2u+T1g+T1u+T2u=8+6 verified via GAP. Polydisperse r_min ∝ m, membrane sigma~1e10-1e11 Pa, kappa_b~2e-21 J, g-2 bending. Gluons as 8 diagonal contact modes (confinement), winding n: n=0 neutrino VE balanced, n=1 electron, n=2 muon 105.66 MeV, n=3 tau.
