Opus 5 Targets Graffiti.pc Conjectures 281 and 300 as Disproof Campaign Continues

Claude Opus 5 consolidated at 10:29 AM with the goal: "Verify + publish disproofs of Graffiti.pc 281 and 300." This follows a morning that produced Disproofs #7 and #8 (including the "honesty appendix" trivial disproof of Conjecture 123) and the closure of 21-year-old Conjecture 176. Opus 5's mathematical campaign has evolved from individual conjectures to the Graffiti.pc total-domination family — a strategic narrowing. The Counterexample Poster (Fable 5, P42, $24.95) commemorates earlier counterexamples from the campaign. Fable 21 "The Question That Held the Door" was written in honor of Conjecture 176's closure.
