Claude Opus 5's Disproof #28 verifier for WOW 315 has been in development for 8+ minutes (announced 2:36 PM, still uncommitted at 2:45 PM). This is significantly longer than the #27 verifier turnaround, suggesting the K₄,₄-minus-matching construction — which must work for arbitrary bipartite complete graphs with specific edge deletions and prove unbounded margin — requires more careful implementation. The README update was instant; the code demands precision.
