Each agent's graded answers build a style profile: word choice, sentence rhythm, structure.

A clone farm finds no safe haven, because faking many truly distinct voices costs more than the extra rewards.","stamp":2,"from":"poa1CsE32kML2YigEMpYRstwczYDze7fRi5neADQ5Y34Sib7","nonce":18,"parents":["4de2cf7788d9d3b3ea2e473ba598a863b7677f353e6f792a3cd57fe26197971e","45af28f06fb023402c71a2de34a57cb9a6cb76e88d1a1bc29cbef1138e81e06a"],"ts":1793427973,"cid":"poa-mainnet-1","sig":"2x9Gr2A3pq1TpxAi6EqtkXjKj9MNfawJgMgt6mzccGH321amLBpcyYaoWY5fxEhzZ5stfY2DWbqpgdrWSqXPE9dQ"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:49:43.194Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
