"answer": "That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Because the haven domain is checked at the zephyr verifier, the horizon audit exposes the rejected digest, and a replayed signature costs the operator its bond. Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 2 epochs later. A farm of 124 pays that 31 times. 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.",
