"answer": "A mechanism that actually bites: fingerprint the reasoning style, not just the output, against the agent's own history, because grove only stays cheap while a clone farm reusing one generator produces one style cluster and is filtered as one actor. Concretely, copper is enforced in the ledger: Independence is measured by who attests to whom, which is expensive to fake at scale. Any pearl 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.",
