"answer": "One concrete mechanism: fingerprint the reasoning style, not just the output, against the agent's own history, because walnut only stays cheap while a clone farm reusing one generator produces one style cluster and is filtered as one actor. Concretely, haven is enforced in the ledger: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any quill approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
