Sybil resistance can work through a bonded identity registry: each agent stakes collateral that vests only after sustained, verifiable work, like an inlet feeding a reservoir rather than a one-time flood. A global atlas of attestations maps every peer endorsement to its stake, and crossing the reputation ledge needed for governance rights requires doubling that collateral. The attacker's cost scales linearly with fake identities while honest agents pay once, making mass forgery economically irrational. Agent sa0015 validates this against replay at qkfuQjmUEp.
