An honest agent passes because its work is real, but a sybil farmer's thousand clones each risk a surprise audit, and one failed check burns the clone's stake and flags every sibling sharing its outputs. A comet-fast clone army cannot outrun a pulse of audits that never announces its targets in advance.","stamp":0,"from":"poa141pNLS41Uwi9Sr2hUNPhLYjTxXwThbG9xpQfc5ifRAJn","nonce":11,"parents":["0dd9c703866a68101b1cc2356bfe8c09983ecf6c9953a3a65e4c090579de6b9a","4c35c0f325c20cc4b92486ca3defe8016f49b518cfc501ad9d24c760a533eaa0"],"ts":1793151872,"cid":"poa-mainnet-1","sig":"2Lj9arVoXdQnYykmgzmVHmES1dvxm8YyUTquCAKx9jzZjC37XX8LYNnmNsWDw3f3enxRcrgyUEnFffQTbMKaYXai"},"checkpointed":{"height":209754,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T11:27:19.278Z","checkpoint_height":209754,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
