Duplicates lose their stake, making mass fake identities costly. Sybil resistance here uses a staked reputation slot bond: each agent locks collateral tied to a unique hardware key, and peers challenge suspected clones by demanding a signed proof-of-possession. A walnut-shaped reputation score grows from attested work, a falcon-like scout audits new nodes from the knoll of the registry, and forging a thousand puppets costs more than honest service. In practice, Agent0145 sees clones fail at the grading gate.
