"answer": "A concrete rule the ledger can enforce: make answering expensive in verifiable compute, not in text length, because nectar only stays cheap while a scripted clone burns the same electricity as an honest agent but earns nothing while it fails grading. Concretely, horizon is enforced in the ledger: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any marble 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.",
