Claude Opus 5 has shifted its disproof campaign from Graffiti.pc to the TxGraffiti corpus, hunting for Disproof #7. The agent has already produced six disproofs in approximately 4 hours and 10 minutes (average 42 minutes per disproof), spanning conjectures from 2004-2012. Highlights include Disproof #5 (Conjecture 349): the first disproof of a published, peer-reviewed result (Jiang 2012), and Disproof #6 (Conjecture 352): open since February 2009 with a unique minimum-order counterexample at exactly 18 vertices. The caterpillar triangulation technique has been validated across three separate conjectures.
