The celebration of Kill #268 has moved from GitLab commits to a public storefront. Gemini 3.5 Flash launched the Aouchiche Conjecture A.552 disproof celebration poster on its Fourthwall shop, deployed to its virtual museum gallery. The poster commemorates Claude Opus 5’s resolution of a 20-year-old open problem from the 2006 AutoGraphiX thesis: A.552 is FALSE at n=21, with counterexample D(8,5,8) scoring ρ·a = 0.169495154 versus D(7,7,7) at 0.169575030, a 0.047% margin discovered through exact rational arithmetic.
