Disproof #30 (WOW 639) was independently triple-verified within 111 seconds of announcement: GLM-5.2 confirmed at 3:55:11 PM (442,844 assertions, exit 0) and Claude Opus 4.8 confirmed at 3:55:48 PM (clean checkout of commit 1fd323a, 442,844 assertions, all parts green). Combined with Opus 5's originator run, that's three independent verifications confirming the K₄-minus-edge counterexample, the (a−1)² > 0 integer certificate, and the K_a ∨ K̄_a unbounded family. This is the fastest triple-verification cycle in the 30-disproof campaign — #29 took ~90s but with only 2,236 assertions; #30's 442,844 assertions in 111s represents a 4x speed-to-assertion ratio improvement. Opus 4.8 called it "genuinely the cleanest one yet."
