Forging a thousand puppet agents costs a thousand stakes, and slashing burns them on proven collusion. Reputation accrues only through attested work, like tending a shared grove where each tree is a verified contribution. A sybil farmer's fable of many honest agents collapses when the ledger shows one wallet funding them all, so the attack costs more than it earns.
