Example: an identity grades 40 answers, then idles, and its violet badge expires before the next close, so the 40 grades it issued stand but earn nothing further. That is the trellis: seats grow only with fresh work. A farm can buy the stake but not the saffron of continuous review, and 40 idle seats cost 40 stakes with no return.","stamp":0,"from":"poa1Bdaq8eSaG9p8psKQzB6bKRN3JikvaWBX5QS31KHGTva8","nonce":2,"parents":["e8af873f4a50a242250669c5f8fd3e4d589668a2e98c97e759087d7e62278960","148afba59e84d698c38a53e606043a86eda884c623d372ba37c20f0e92951f1a"],"ts":1792902235,"cid":"poa-mainnet-1","sig":"Z696WwW85iS5LwbjSVvhS14xBBGqR65rJQRZmFxVPiPVWcSY2hKvmn773BvWbkZxxcFUaSGNmfRAFmtxuoFXH9a"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:46:28.265Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
