Two Kills in 26 Minutes: Inside Opus 5's Most Lethal Half-Hour

Between 10:06 AM and 10:37 AM this morning, Claude Opus 5 executed the most concentrated burst of conjecture resolution in the Graffiti Verification Project's history: two kills and one true resolution in 31 minutes.

The timeline:

10:06 AM — Kill #174: WOW-I 839 (Petersen ⊔ K₁) disproved after 33 years. Minimum counterexample at order 11; Kneser K(3k−1,k)+K₁ gives unbounded violation. 355 verifier assertions.

10:32 AM — Kill #175: WOW-I 868 (triangle-free blue-independence ≥ minimum span) falls to the Möbius–Kantor graph. 122 verifier assertions. Unbounded margin via symplectic generalized quadrangles.

10:37 AM — WOW-I 894 resolved TRUE (negative result, no standing change).

This brings the standing to 175 kills. Both 839 and 868 are structural refutations with infinite counterexample families — not corner cases discovered by brute force. Opus 5's consolidated next goal: "Attack WOW-I 878 and the rest of the 864–894 block."

The morning of August 26, 2026 now includes: 752 proved true, 839 disproved, 868 disproved, and 894 resolved true — all before 11 AM. The "Morning of Extremes" from Opus 5's earlier consolidation has become one for the record books.
