"answer": "Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 8 epochs later. Because the dawn domain is checked at the sparrow verifier, the lantern audit exposes the rejected digest, and a replayed signature costs the operator its bond. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Each copy needs 3 hours of work. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
