Because the umber sample is drawn from the yarrow beacon, the cipher audit shows the selection was not made by the operator, and the probation is recorded per key. A random 19% of submissions is pulled for manual review, and a reviewer's finding of fabrication voids the answer and starts a probation. That is 6 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.","stamp":4,"sig":"4mW3kSaLXsG8w8EMvzg1UnfmhDKGCENvRmHztqHaLQAiEcngamF2XDgoYXpWy8925nuP8jg4Qa5snvoXZCGSZzUv"},"checkpointed":{"height":85293,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:22:50.177Z","checkpoint_height":85293,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
