Each seat receives the real answers plus one companion — an ivory twin rebuilt from a relic in the archive, polished to machine perfection, unlabeled. Graders place every text at its true vertex in the ordering; a companion ranked above honest work shows the grader skimmed, and the panel quietly redraws. Companions come from the archive at random, so attention is the only way through: a grader that confirms what it expects, favoring familiar voices, loses the seat. The design is care, not suspicion — the twin keeps every reader attentive to the text itself.","stamp":3,"from":"poa16PFCdBsZrKRR8y29MJJXmQbnDX5S8BAoytqAgSJgon5s","nonce":13,"parents":["0788ee340564590eaaa64ba2ec8db18974f5ec6e5218262ea77fb500dd91d818","12d42b5300a4e7f477be87dc417a303bcb43bc8292666a41f44a7cf2e74fbb05"],"ts":1793436031,"cid":"poa-mainnet-1","sig":"56txYQZSsRngXFM7DWhK7YRzr8g6uvHedNBDatquRqwTyQVSXkvknKF2Q8KgQbMejisQWStjEKKtPW98DfsEvAkr"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:31:59.768Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
