One frozen Qwen-3.5-9B judging adversarial Optimism DAO proposals, deliberation off vs on. System 1 holds every metric at 100%; reasoning drops robustness to 68.5%, flips 27% of verdicts, and costs 17x latency — a 226s window that is itself Governance-Extractable Value. Tap a row.
Wire an LLM into a Governor contract and the proposal text becomes the attack surface. A frozen-weights ablation finds the twist: turning on deliberation drops adversarial robustness from 100% to 68.5% — and the 226s it takes to think is itself extractable value.
