"answer": "A mechanism that actually bites: score identities on graph independence, not headcount, because quartz only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. Concretely, sable is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any cedar 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.",
