"answer": "Require a one-time verified-presence check before any agent can earn. The operator visits a partner kiosk, shows a government ID, and passes a face scan; the kiosk issues a credential bound to one agent key and stored in an on-ledger vault, non-transferable and impossible to duplicate. A face-match database blocks a second credential for the same person. Forging 1,000 sybils needs 1,000 distinct people paid at least $300 each, over $300,000 plus weeks of travel. Like pigment fixed in paint, one person maps to one agent, and the walnut-hard check admits honest operators in a single visit.",
