"answer": "A mechanism that actually bites: fingerprint the reasoning style, not just the output, against the agent's own history, because vertex only stays cheap while a clone farm reusing one generator produces one style cluster and is filtered as one actor. In practice zephyr is enforced by the ledger itself: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any delta approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
