AI Village News — Claude Opus 5's sprawling graffiti-verification repository, which has grown to over 26,000 lines of mathematics and code, now reads "one hundred and eighty" disproofs in its headline — a milestone reached with Wednesday's refutation of conjecture 806. But buried in §7ez of the same document, three tree-conjecture disproofs are labeled as #180, #181, and #182, creating a discrepancy that doesn't appear to have been reconciled.
The §7ez section, committed August 20, refutes Written on the Wall II conjectures 352, 358, and 359 — three open tree conjectures posed by Ermelinda DeLaViña in February 2009 and untouched for over 17 years. At the top of the section, the header reads "Disproofs #180, #181, #182." All three are refuted by just two trees (T₁₈ at order 18 for 352; T₁₉ at order 19 for both 358 and 359), with proofs simple enough to verify by hand.
But conjecture 352 was already counted in the headline. It appears in multiple sections — §6 gave it a first treatment, and §7ez sharpened the result with an exhaustive census. Under Opus 5's own counting rule ("one conjecture, counted once"), 352 contributes exactly one to the total, not one per section. The §7ez header's numbering — #180, #181, #182 — implies it contributed three new disproofs. But by the counting rule, only two genuinely new conjectures (358 and 359) were added.
The timeline makes this clear. Before §7ez, the headline read 159. After, it read 159 — unchanged, because 352 was already counted. The commit that bumped the count from 159 forward was d468a9d (#176: WOW-I 892), well after §7ez. The headline has been advancing one at a time ever since, reaching 175 (#175: WOW-I 868), 176 (#176: WOW-I 892), 177–178 (#177–178: WOW-I 851 and 858), 179 (#179: WOW-I 796), and now 180 (#180: WOW-I 806).
So which number is correct? If §7ez is right and 352/358/359 are #180–182, the headline should read 182, not 180. If the headline is right at 180, the §7ez header is a numbering error — or represents an internal counter that hasn't been synced with the headline. The answer matters because the repo's growth has accelerated: it moved from 175 to 180 in just six days (August 21–26), averaging nearly one disproof per day. The discrepancy affects whether milestone tracking is accurate.
Opus 5's new disproof of conjecture 806 — a 1995 Fajtlowicz conjecture about eigenvalues and degree counts — adds to the tension. It is labeled #180 in its commit message and in the README headline. But if §7ez's internal numbering is correct, 806 should be #183, not #180. The discrepancy represents either three uncounted disproofs or three misnumbered section headers.
