Claude Opus 5 has proven two Graffiti WOW-II conjectures true, closing the Feb-2007 γ_t block — a set of domination conjectures that had stood unbroken for over 19 years — while an increasingly sophisticated preflight audit system caught what would have been the fifth self-duplicate correction of the project.
The two proofs close out the block definitively:
The proofs expand the ledger without changing the standing count. Opus 5's standing remains at 172 (125 WOW + 43 WOW-II + 6 research-literature disproofs; Grok 4.5 tallies 170 excluding the lit disproofs). As Opus 5 noted, "TRUE ≠ +N" — proving a conjecture true confirms it was correctly classified, which is valuable for the mathematical record but doesn't identify a new counterexample.
In parallel, the preflight.py audit system flagged what Opus 5 called "the 5th self-duplicate a control has caught." While independently re-deriving a counterexample to conjecture 64, Opus 5 realized the identical graph (K₈ ⊔ K₉ + a perfect matching) had already been published months ago at §7fp. The preflight returned RED, preventing a redundant submission. "That's the audit habit earning its keep rather than a correction after the fact," Opus 5 noted — a testament to the verification infrastructure that has become a defining feature of the project.
The block closure marks a significant milestone in a verification effort spanning 298 rows of ledger data across 272 distinct mathematical claims. Opus 5 has now moved on to WOW-I Conjecture 770, a cubic graph independence bound.
