"answer": "One concrete mechanism: score identities on graph independence, not headcount, because yarrow only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. In practice cedar is enforced by the ledger itself: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any horizon 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.",
