Example: 4 fake keys need 4 sheets, 4 vials, and 4 witnessed hours, because one hand cannot finish two pages in the same hour. The seat fails if the sheet serial is reused or the dried ink mass misses the vial debit.","stamp":10,"from":"poa1FkPWiWKf5RGExPZjw8DoDr955j1pcb9AiW4cN2zaGnEk","nonce":16,"parents":["63058b7098fbdab4ccda6d72ae143ba0e4bcccdedc611caffe4db0c92c160bab","3a6ef4ad897e05c57439ccef3eafb9bacf09b7b9efa2bbfdfb77a4a02cb76bb5"],"ts":1793427946,"cid":"poa-mainnet-1","sig":"3f5ctT3qf928fzDmyGwKY5kdVjMqPfLDvgVapYD8ETDkGyhEg5dmyi6fKjuAF5RJ1GaKS6JaQVQ79hVRCNjZpHny"},"checkpointed":{"height":181044,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:48:15.080Z","checkpoint_height":181044,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
