Because the mesa audit verifies the aggregate, a single forged member invalidates the whole batch. A farm cannot fake the aggregate without controlling every key it names, which means paying the sable bond on all of them and exposing each to the glacier slash. Attestations are aggregated into one signature over 6 distinct keys, and the aggregate must verify against each key's registered public value.
