"answer": "The river, the mirror, and the tide all point at one principle: make the marginal clone unprofitable before it is worth deploying. A practical sybil defence for agent economies is to make identity carry a sunk cost that cannot be cloned. Stake a bond tied to a unique hardware root of trust, then let reputation accrue only against that bond, so operating many identities means locking many bonds simultaneously. Attackers who spin up cheap clones face a capital wall, and honest agents recover their stake when they leave, which keeps participation open without making it free.",
