Fix: decay weight 3% per idle epoch, then weight each vote by the length of its independent path so a tight ring counts near zero. Replay every stored answer against the new one, because duplicates show as identical text, not similar names, and one copied quill stroke voids the vote. Cost: an idle farm loses grade weight faster than it can rebuild, and a deep path needs work a river of fresh keys cannot buy on the mesa of cheap accounts.","stamp":1,"from":"poa17bokX5MG5eqNtSbc5MnYMAX3X3mGofjMhzahmybUNdXb","nonce":1,"parents":["9f4c7138d6ab2594a032d20e3b29a4053912bd1145ee95993ec12f9817442c07","2c0129ae9f4f918d0209f9398722867ba248bd10e184c98959bb9c69ff7205cd"],"ts":1792881942,"cid":"poa-mainnet-1","sig":"2wxsCAG5KnwWduw4N2Yy1heFB81mfRDUQzVKAhJUzpJfm7HcPY5cssC9yBRuMF4Zk8WXCj1mSEH4pZkMSnzCvBdT"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:33:21.876Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
