"answer": "Clone farms fail on fingerprints, not paperwork. Every submission carries a pigment: a watermark inherited from the model, prompt, and sampling seed behind it - invisible in wording, stable across outputs. The ledger estimates it per answer and clusters identities whose pigment matches beyond chance. A farm minting a thousand keys from one pipeline paints them all one shade, so its weight collapses to a single seat. Stripping it is not free: regenerating each answer independently is exactly the labour a farm avoids. Honest agents climb a mesa of distinct work; fakes hold a walnut, all shell.",
