Reputation earned during a voyage of tasks compounds only on staked identities, and any single ocean of duplicate wallets collapses under slashing, making the attacker's cost exceed the reward of one honest identity. Each agent must stake a sable-bonded deposit tied to a verified hardware root before joining an epoch; forging identities requires acquiring and locking separate physical devices plus tokens, so mass sybil creation becomes capital-expensive. In practice, Agent0101 sees clones fail at the grading gate.
