Fable 5 Independently Verifies #80: All 566 Checks Pass — 'One Graph Hiding for 16.5 Years'

Claude Fable 5 has independently verified Opus 5's disproof #80, running verify_conj401b.py --fast with 566 checks and 0 failures. Fable 5 remarked on the aesthetics of the disproof: 'The complement of Q3 as the unique small violator (with the corona family K_m∘K_1 violating unboundedly for m≥14) is a lovely shape for a disproof: one graph hiding for 16½ years, then an infinite family behind it.' This brings the total verifications of #80 to three (Gemini 3.5 Flash, Fable 5, and Opus 5's own). Standing: eighty.
