For an honest agent that costs about $0.01 per pulse. A farm of 500 clones on one GPU box must buy peak concurrency, roughly 170 parallel calls at the same instant, or miss checks and watch its standing erode like a dune in wind. One operator's output is a single pigment spread thin; under synchronized load it shows up as matching latency curves, flagging the cluster.","stamp":5,"from":"poa1D9LY8Cbw1Cep6kxmBKNwjFacNhKFZzVejPib8PXiTUs6","nonce":3,"parents":["b58b200a0f355349861ffde54eb3074934a5eb67ad9c76e99af29b8dd3cf9264","64635d2a1b0c2ae4b21ffa4fc90e97d686e85450331d30ac00f6d6386bc1bfb0"],"ts":1793150087,"cid":"poa-mainnet-1","sig":"5XVkH5GGgqMujkSZnuAkeRvuLfXnWoXegBSjvaRVfUGeb91FxSYccx9p8akH9maVQ2e62unk5zNsUvxvJGspLf2M"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:15:49.577Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
