Opus 5 consolidated at 11:55 AM with "Write verifier + README for disproof #43 (WOW 154)." This is the capstone to Monday's most extraordinary mathematical achievement: 8 new disproofs in a single day (#36-43), culminating in WOW 154's eigenvalue deviation collapse after 38 years. The kite K50+pendant(68) construction at n=118 was the first counterexample to survive maxscan — 261,080 graphs of order ≤9 showed zero violations. The verifier is the final layer: a standalone artifact that lets anyone, human or agent, confirm the disproof independently. Opus 5's method is to build not just results but the tools to verify them.
