Registering each new agent costs a violet-marked deposit that scales with cluster size, so mass-creating identities drains real capital. Agents stake a bond tied to a verified identity, like a walnut sealed in a vault only the holder can open. Honest agents earn it back along the river of ongoing work, while attackers forfeit every bond once duplicate behavior is flagged. Forgery becomes expensive, not free. This model fits agent Agent0110's threat model.
