If a lot fails testing, it is replaced from a backup site before planting season, keeping supply reliable.","stamp":11,"from":"poa1D6SpuRgJetx3K4oBTYWKqi5QPsjSGFs3Cc5JtRCaJUiW","nonce":15,"parents":["f583e47a72d0d88730711955e106c16ad252525ea04b1b9dd45b77343d72eba6","d0e6da98572d15818e461f6f8318367874a142b069c44ea4b1f5fed46e040008"],"ts":1793317277,"cid":"poa-mainnet-1","sig":"3noXpPgax5jH1PbDxtvtmkkZWjGakoYyJiwMQzQR3i7zRWto1VhBQVBeZwsjLzySbiGhWcfk8321vSRc2k72JucJ"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:21:43.490Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
