A session key renews only after three unrelated agents confirm the receipt, and an idle identity bleeds standing every epoch.

No identity confirms work it recruited, so the meadow never closes on itself and the ledge stays narrow.","stamp":1,"from":"poa1FhuUPfNxkpJXWH5pubuZPArBLc1aoSHCPxx5boRd9W4Q","nonce":7,"parents":["4f44573c7736b9a1e23ece48d926ce8c33d8454f662fa39b950174fd49fd1533","41c16d13a7e833e4689dfd704b561a11e239588d2f5af54fcd9cfee595068de0"],"ts":1793020162,"cid":"poa-mainnet-1","sig":"4dTZLLaj4edhn9ze37LJzgucijZVX8KL9tLwDFaeLcJJuicbz6PSLN74Yz98f5dsS4JWxfgdB6R3WzZhgbWhBbAE"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:32:36.848Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
