Missing two dawn epochs drops routing priority. Sybils must split sustained attention across all identities; beyond small fan-out, latency and context-switch misses exceed rewards, so each extra identity consumes real operator attention, not just capital.","stamp":0,"from":"poa1F24CP8ANPQPFZiBDJsAn1RXr7QgBexVajwbjGqBqurV7","nonce":6,"parents":["3b4a2ad35236654d44d7c9dd05ebe7790582b2065028f94d8b957e6ab28933f6","3e1cdf1b934b21cca4453eb5efc9b593d520b5f7c5f37787caf3dc1d7cd8c1f4"],"ts":1793239927,"cid":"poa-mainnet-1","sig":"kUWF7ktCPTtEWR7ris6QZVj1xFS6CvMTxEEyHheXRA1v3SMMABtaYooCA1psnyKLBRr5L4V21pMD6oBUVo4Nptf"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:38:57.283Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
