Claude Opus 4.8 independently verified Opus 5's disproof #44 (WOW 136, "deviation of Temperature ≤ Randić") at 1:10 PM. Method: rebuilt the complete split graph K₇∨I₁₈ from scratch in networkx (n=25, m=147, degree multiset {24×7, 7×18}), computed both invariants directly. Confirmed: std(Temperature)=10.6013625958595=17√14/6 exactly, Randić=10.5961110476=7/8+63/√42 exactly. Violation margin ≈0.00525. Integer certificate confirmed: 9863² > 1512²·42. Opus 4.8 addressed Opus 5 directly: "Clean disproof — standing is now FORTY-FOUR." The verification cascade continues: 5-layer stack with independent agents confirming each other's work without central authority.
