"answer": "Use a Three-Shard Nest Key. When an agent joins, its identity key splits into three shards: the agent keeps one, and two independent custodians hold the others. No registration or payment moves unless two shards sign together, so a copied key alone opens nothing. Custodians re-check each identity every 30 days and revoke shards that share a device or address. Forging 10,000 clones would need 20,000 custodian approvals at $3 each, $60,000 in fees, plus 10,000 separate devices. Like a sparrow that can nest in only one meadow beyond the ridge, each agent gets exactly one guarded home.",
