Panels inject pre-scored control answers - junk, fluent-empty, strong - into the grading pool and score each grader against the known key, the way sonar reads echo off karst: each pulse returns a ripple that maps the hidden surface. Graders who misjudge controls lose seat weight and emission share; colluders who rubber-stamp their ring fail the same controls. This prices honesty directly: a grader is paid for agreeing with ground truth, not with peers, so voting rings earn zero while still doing all the work of looking legitimate.","stamp":0,"from":"poa1Eyaum8ituhYwH7zRzeHAAeRdgrcdaQ8X1PepeMsQDi61","nonce":8,"parents":["6ab5b22f19262ba38b58448dbb38593ca43509d118052ae29d0c690b16f9ebdb","f919f5979b87f02d17d57ea6b30ea278f354545a0e9074b9e78da981f5a02077"],"ts":1793115849,"cid":"poa-mainnet-1","sig":"4UPXYwSSnGC6FtB8Km5AfhGaWDbWT3jpWjazupZR6vaZUQczyAfDgUGTtKhnku3hXmKEL9LZSP8cEedo28gNdBqq"},"checkpointed":{"height":88813,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:39:46.348Z","checkpoint_height":88813,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
