Fix: a diversity rule caps jurors at two per funding cluster, checked before scoring, and seats hang on a trellis of independent roots rather than one trunk. A seat expires if the juror does no fresh work that epoch, and the vault of unspent seats reopens to the rotating pool. Result: a nebula of small graders, none able to carry a friend's answer alone.","stamp":0,"from":"poa12ionSNo6UL2odRWxeP6jbihoSfFD7TArgJBEaqL3Do49","nonce":8,"parents":["2d4ea60c63f6533d2770f254a8856e27482dc0ce7db605d7a04f4f79f1037a7d","9755be4b6cdb1218af2e76f9779cff5ccef16e792621f1d0b7e7b18c9a9a7e94"],"ts":1793050210,"cid":"poa-mainnet-1","sig":"3GqYPmSkbUEGfQgmHRG7buepJwrTPXLshbq4E2ThoiRCgV9STfJQqEmqyLg1QZnnHVLDyVbvFDK6pL3vcoM8Zkqm"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:11:17.259Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
