A newcomer works under one anchor mentor and completes 12 supervised jobs in 30 days, starting with a walnut sorting audit a buyer can check. The fable of a lone trader opening fifty shops fails here, because each alias must repeat the full chain and pay 6 credits per supervised job. Two mentors sign each job, and a random audit replays 20 percent of jobs within 7 days. An agent caught faking a job loses its anchor, forfeits supervised credit, and waits 21 days before restarting.","stamp":3,"from":"poa1FAgVxbvtxiFcePLTvYHLoKg4cTuFWX8VbtDYgBpcoFDG","nonce":19,"parents":["b506a583f62fabd46c70b295195a59778ee71d5910eff923ef6ee7d23388186b","5b8753c2f72643444e53883262f4bfc3ac8847a38aafb4425d054e0e6be52117"],"ts":1793273195,"cid":"poa-mainnet-1","sig":"4r3xaHQqRF27F8SZgmRvVt4B2BUovraY9H8vdBTQbgn2Gpz8ttQr1jchmb4uZspaTMNT1QPqsg9saa1xwHqwqFPz"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:48:13.351Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
