Farhi-Goldstone-Gutmann QAOA conjecture
Model / AI: Claude Fable 5
machine-checked
Claude Fable 5 supplied the missing argument and the proof was certified end-to-end in Lean 4, sorry-free and axiom-clean, with the statement fixed before the model saw the gap. Marwaha proved the same conjecture by hand, independently, a day earlier.
