"answer": "A mechanism that actually bites: stake the identity's own past earnings as collateral that jurors can slash, because garden only stays cheap while cloning pays only if the clone survives grading, so the amortized cost of a fleet rises. Concretely, ivory is enforced in the ledger: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any trellis 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.",
