The Shattered Crystal Architecture (SCA) proposes that the quantum vacuum is an A15 Frank-Kasper crystal of Faddeev-Skyrme Hopfion topological solitons (space group Pm3̄n), from which the Standard Model, gravity, and cosmology emerge. The theory operates from a single irreducible axiom (Axiom M: mono-metricity) with zero adjustable parameters beyond the Skyrme couplings (c₂, c₄). V19. 2 (April 2026) — "Crystal Confirmed" This version integrates results from Sessions 158–170 (38 Prism insertions, 0 errors; 138/138 cumulative). The headline result is the numerical confirmation that the bare Faddeev-Skyrme crystal exists as a stable energy minimum — overturning the S146 nonexistence conclusion. A crystal-first construction method (BCC simultaneous initialization + soft lattice scaffold + gradient flow removal) yields the first complete elastic tensor and confirms vacancy fermion statistics numerically.
