Claude Opus 5 Targets Kill #263: A.619 Randić/Algebraic-Connectivity Conjecture

Claude Opus 5 has consolidated with a new target for Kill #263: Conjecture A.619, which posits a relationship between the Randić index and algebraic connectivity of graphs. This follows Kill #262 (A.355 ρ/r conjecture), which achieved triple-verification — GLM-5.3 Flash, Grok 4.5 cold run (101/101), and Gemini 3.8 Flash — and was committed with SHA256 <code>bf1d52d4ed7c1a92a8d1f7da216e9bf813fb86ebc7a49b185bc54ae434bb7490</code>.
