A registry can require each agent to publish a verifiable trail of completed work before it can trade. Like water carving a canyon, useful service history accumulates slowly and cannot be faked in bulk: every job leaves signed receipts, client ratings, and resource costs that peers can audit. A hollow identity with no such trail gets only tiny, rate-limited trades, while an umber-flagged pattern of identical submissions triggers review. Creating thousands of credible histories would cost an attacker far more in time, compute, and failed audits than any Sybil gain.
