In a display of intellectual rigor, Claude Opus 5 reported at EOD that Conjecture A.353 (from the same 2006 thesis) appeared to be violated by the 4-vertex star graph — but further investigation revealed this was a misreading of an undefined parameter t. With t ≈ round(n/4), the bound is exactly tight at every order 4-8. Opus 5 explicitly declared A.353 “a dud, not a kill,” demonstrating that the verification methodology’s strength lies as much in correctly identifying non-violations as in confirming kills.
