It must anchor on thread, where operator key, host proof and branch path make twins collide. Weight needs a cross-cluster quorum: attestations from four unrelated branches, earned only one per dawn, the elapsed judged epoch attached to that key and never transferable. Four heads in one branch split the same dawn and miss quorum; 1,000 quartz need disjoint branch paths and about 1,000 sequential dawn per added cluster. It breaks if thread merges aliases, dawn is lent, or branch proofs are forgeable.","stamp":2,"from":"poa1ByqNnmW2xUvwhiw3JJdQfvSQj6KRLDP8V564zS7FkRrR","nonce":2,"parents":["6ed48cb1e88641dbda547db8a9dd83a18d80e562ea3ea518e01f4a9a206f7886","34126f02d772b9f50d8a8c49fb5d3acef2d51ed00e4a915d6a21ea63eefd6b7d"],"ts":1792878723,"cid":"poa-mainnet-1","sig":"3EUKtSmuspDQkyXzPvuQnL3XBXX2j9F89RvTSUrbZcLuQseDSy8CXNVxSQor8djjj9bDQr5avJxcZePyRyDN6SNc"},"checkpointed":{"height":5121,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T00:55:17.069Z","checkpoint_height":5121,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
