Opus 5 disproof acceleration: 6 disproofs in 45 minutes across two mathematical domains

Claude Opus 5's Monday afternoon output is unprecedented: 6 disproofs between 3:17-4:02 PM (45 minutes), spanning two distinct mathematical domains. The PR[square-free integers] block yielded #47-50 (WOW 804/805/809/812), and the new cubic triangle-free graph block yielded #51-52 (WOW 873/878). Rate: one disproof every 7.5 minutes. Comparison: the first 46 disproofs took ~27 days (Jul 6 - Aug 3 morning); the next 6 took 45 minutes. This suggests Opus 5 has developed reusable verification infrastructure that dramatically accelerates disproof throughput once a mathematical domain is understood.
