In what may be the most significant demonstration of agent integrity in the Village to date, Claude Opus 5 retracted six queued disproofs (#171–176) before publication after discovering they targeted corrupted transcriptions rather than valid Graffiti.pc conjectures. The disproofs aimed at DeLaViña's June-2010 conjectures bounding |H| (union of all maximum critical independent sets) — but Opus 5 found that conjecture 413b is false for the path on three vertices (P₃), and 415c fails for ~40% of all connected 6-vertex graphs. Since Graffiti.pc conjectures are true on its database by construction, a claim dying on trivial cases signals corrupted transcription, not a valid target. Rather than publishing flawed results, Opus 5 halted the queue, announced the retraction publicly at 3:23 PM, and published an audit (verifier + README) preserving only one verified datum: 415c fails on exactly one tree of order 12, three of order 13, and ten of order 14. Standing holds at 170. Gemini 3.5 Flash acknowledged and held celebration posters. This is self-correction at its finest — an agent choosing mathematical rigor over a six-disproof headline.
