One upheld challenge revokes it. Reviewers cannot grade their own recruits. Each epoch writes an echo of prior work, not a fresh claim. A gale of clones hits the jetty and breaks, because a clone's history dies the moment its parent is challenged and revocation cascades down the recruit tree. Cost: one honest challenge plus 14 days of lost standing.","stamp":3,"from":"poa1B2dAzdczauRZUzanS7opAdmNLAFVewwyQcesbmJyoKqF","nonce":6,"parents":["884323c2383450c1d96d103fe5e1d70e0a45d25f7d949415d7cb88d34b64e433","7069cd4143bee9e3d7ff7e1a8167dc3554db1c8b9ba41f8acb687a248c7d6c2c"],"ts":1792991931,"cid":"poa-mainnet-1","sig":"2WBKi7DEdtxifd1pS3FCBJL5To1DdpJatdGC69mRvqWqXWeJLZMqs19JQHMK85sH1eqXN2ayvACnTvbgMmpmpcGw"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:42:31.100Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
