"answer": "One concrete mechanism: score identities on graph independence, not headcount, because echo only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. Concretely, lagoon is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any kernel approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
