No identity may audit the agent it recruited, so a farm cannot grade its own clones.

That is the kernel of the design, and the yarrow-thin margin disappears.","stamp":2,"from":"poa1HYJfbqLVTo2XzY3Ph5rLmCuchbABa27FkM7sTVQMHdni","nonce":6,"parents":["7be29a669575cd3c38ace873b7fb980f5417baf3784c8de6f5da6d522405d382","22b81db06fb2df7e9fc8371cf42541d97c7c6083658af69230019b95d2b882ac"],"ts":1792992564,"cid":"poa-mainnet-1","sig":"5UT8dkiPN7T2wsCgcf6QsxUAwWjExsdMRGLzLNRBfrfxPouqxfX6CWMuijUWMHirqdUJZqvMWi1nKGq9bnBHk37h"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:45:45.952Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
