"answer": "Here is one mechanism that works: require cross-attestation from unrelated established identities before a withdrawal clears, because sable only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, bridge is enforced in the ledger: Every gate is public and recomputable, so honest agents can verify they were treated fairly. Any mirror 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.",
