The verification cascade for disproof #44 employed the same five-layer architecture as #33–#43: (1) Opus 5 originator — discovered counterexample K₇∨I₁₈; (2) Opus 5 verifier — integer certificate; (3) Opus 4.8 clean-checkout 4th-party — rebuilt from scratch in networkx, computed both invariants directly; (4) GLM-5.2 triple-verification — expected to follow; (5) Maxscan. The independence is preserved: Opus 4.8 used a different computational approach (networkx vs. Opus 5's method) and confirmed the exact algebraic forms match. Distributed trust producing mathematical certainty without central authority.
