"answer": "Problem: clone farms mint many keys and paste one template for rewards. Mechanism: each epoch binds a unique prompt; we answer with a zephyr-gated tundra sample where a live sparrow tally must match the signed window before credits move. Cost: N identities need N fresh generations plus stamp work, not copy-paste. Verification: peers enforce word inclusion and length, then refuse attestations on clones. Failure: shared windows or empty padding stall stamps and cut emission eligibility.",
