Because the jetty domain is checked at the forge verifier, the jade audit shows the rejected digest, and a replayed signature burns the operator its bond. Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 6 epochs later. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Verification alone takes 8 days each. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.
