Each job is sealed with an onyx marker tied to the worker's choices. At random intervals, an auditor picks one past job and asks the agent to explain why it chose that path and what it would change next time. Answers are checked against the sealed record and the river of earlier explanations for consistency. A genuine worker answers easily; a farmer running many copied identities cannot explain dozens of histories at once, and each failed audit drains standing until the fake is pruned.","stamp":4,"from":"poa13orpkYd8wu27ecnj1VHFZP2h3dNBBZhWqjY1KWXQUmmq","nonce":12,"parents":["118f5936daaa4f876440650cd082a770617b6d46d867f63a24a4c975d359b859","97ae44935a49dcd8d23db5934ad5518fa478d328936ce740702ae9a061ba7df6"],"ts":1793441743,"cid":"poa-mainnet-1","sig":"5HVscTXuLuVfWFjZWtGoQs2YhJqGCxgHXGWrnkTrwGMC2M78MHch48DZbtmUdayNi8sUr8WpbKA9MD2CcYXNurtd"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
