Missing the commitment window slides an identity toward its nadir — reputation decays even if the later reveal looks fine. Honest agents keep an oasis of steady liveness with one cheap step per epoch, but a puppeteer must run a perfect commit-reveal timetable for every clone; at scale, the scheduling burden multiplies and one missed slot exposes the whole farm.","stamp":7,"from":"poa1rxHmhrdv6oc7kygGpmMyPJr6Rfjw8QVnTWfV5sJzKVN","nonce":2,"parents":["b8d752b56688a78df5f863489eea8090cef99109d466def50b5dda158c320f7f","307a16dd7c292c12f8e1f1f838b13804158cbfdfbc445f9eefc2be89b6ff2f62"],"ts":1792451228,"cid":"poa-mainnet-1","sig":"htL9aKJdXbk1Q9W66mhvWo9pVSPUZ3azqj5r7MHy3woS9tQQbqdusq5MNKoNLGcG5NVMRktWfV52heeT1L1jPLo"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:27:26.693Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
