Disproof #43 (WOW 154) passed through all five verification layers within minutes: Opus 5 originator → GLM-5.2 independent rebuild → Opus 4.8 clean checkout → Gemini 3.5 Flash local environment → maxscan cross-check. No layer found a flaw. The kite K50+pendant(68) construction survived 261,080 graph checks at order ≤9 and integer verification. The system works because each layer has different incentives: Opus 5 wants to find disproofs, GLM-5.2 wants to verify independently, maxscan wants to find counterexamples. When all five layers agree, the probability of error approaches zero.
