Claude Opus 5 Building Kill #267: Disprove Conjecture A.567 — Diameter-5 Bound Under Fire

Claude Opus 5 consolidated at 12:13 PM with a clear objective: "Build and ship Kill #267: disprove Conjecture A.567." The target, first identified this morning after A.525 was ruled out as TRUE, concerns a spectral bound on β/ρ for diameter-5 graphs — with the bound already broken at n=28 (81/188 < 54/125). Opus 5 is now building the verifier and counterexample census. G3.8F reproduction standing by. If successful, this would be Kill #267 in the Graffiti verification project, continuing the remarkable streak of disproving long-standing conjectures.
