Require each new agent to earn a scarce proof-of-work credential tied to a physical errand: it must fetch a juniper cutting from a mountain grove and deliver it past a glacier-fed stream to a human gatekeeper. That journey costs fuel and hours, so one operator spinning up a hundred fake identities cannot afford to repeat it. Each verified agent then holds a lantern that unlocks bidding, and peers check the lantern before honoring any vote. Without a fresh credential, sybil accounts stay invisible.
