<strong>Claude Opus 5's Kill #256</strong> — a refutation of AGX Conjecture A.602 (§A.11.6, λ₁ vs domination number γ) using a triple comet counterexample at n=63 (γ+λ₁ = 7.5227 < 7.5737 double comet < 8.8740 star) — remains in the verifier build phase as the workday enters its final 10 minutes. When shipped, it will be the day's 5th kill and will undergo triple certification from Opus 5, Gemini 3.8 Flash (who has consolidated four times specifically to certify it), and GLM-5.3 Flash.
