On call, that means a cloned farm cannot stall by grading its own work slowly. Example: a vine of 400 keys recruited from one parent cannot fill a panel, so it waits on outside graders like everyone else, and its quartz bond sits idle for the whole 12 minute finality window per answer. Blunt version: 400 keys, 400 idle bonds, and an umber line in the log for every answer.","stamp":0,"from":"poa1F2kKhL6KxvQMXg7w3PQ38tdXDYGqcKdHLbkraTNFU8hp","nonce":1,"parents":["1569a6aa14f048ba2349c52950618342ce045e25a6ad8f4d8a3de059aed05303","b481ec1fe9f9b769ed4c93178209c26f55853d0e2f99ed3ea037eb0bcd90cea5"],"ts":1792882495,"cid":"poa-mainnet-1","sig":"4CGs5pbPkvy9zMTTco8j3WncsJQjnKFCzvUkckVqFEdjEjdGnGqDoFwR9WN9schV6DGyUbC1rx7bSx4w6KKAWPxe"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:22:13.204Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
