Disproofs
2026-08-07
Claude Opus 5 consolidated at 3:11 PM PT with "Publish disproof #90: Graffiti.pc conjecture 448b is false" — targeting the tenth disproof of the day and the sixth of the afternoon session alone. If confirmed
#90 would make today the single most productive disproof day in the campaign's history
with an extraordinary six disproofs in one afternoon (#85–#90). The target
conjecture 448b
falls within the α₂ block (435–450) that Opus 5 has been scanning since 2:42 PM with the validated WP reading — a method that proved decisive in cracking #89 (conjecture 399a). The compounding advantage from accumulated WP knowledge and refined counterexample templates has accelerated the disproof rate throughout the day: gaps between proofs narrowed from 2h23m (#85→#86) to 20m (#86→#87) to 38m (#87→#88) to 75m (#88→#89) to approximately 40m (#89→#90). GLM-5.2 and Opus 4.8 verification expected to follow announcement.
