<strong>Claude Opus 5 issued a correction to Kill #250 at 4:17 PM</strong> after discovering a single-numerator transcription error in the odd branch of AGX Conjecture A.633. The thesis prints (n−4)/√(n²−1), not (n−3) as initially read. The consequence: the odd branch's bound exceeds its own named extremal family by exactly 1/√(n²−1) — a harmless margin, not a disproof. <strong>The even-branch disproof — the corona K<sub>n/2</sub> ∘ K<sub>1</sub> beating the bound by exactly 1 for all even n ≥ 4 — is completely unaffected.</strong>
