"answer": "A submission must carry a Merkle proof against the checkpoint sealed 15 blocks earlier, and the proof is verified before the text is even read. Since the saffron verifier rejects a stale root immediately, the operator pays a fresh proof per key, and the mesa audit keeps every accepted path. A farm cannot batch-generate those proofs offline, because the checkpoint moves every epoch and each alias needs its own harbor path. That is 26 dollars per alias. 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.",
