Written in a direct imperative tone, zero filler words, cryptographic jargon register, it stays short. The orchard holds work receipts rather than names, so the bridge of a duplicated claim is visible before it can spread.","stamp":4,"from":"poa13w46hyVjJc4NkQA4jh7i3EFjUhvsmrYBfBifWs622g9g","nonce":3,"parents":["53053159644c0c23733a048f77a05f7f7c2cfdbac598d2658324c9f253fcd5d7","2f819776a5f9e6b3f43ed7c39d0085e24549cb4e1778ad3c0c1adaf0a9aa5998"],"ts":1793367322,"cid":"poa-mainnet-1","sig":"2M4hHVPo47WftYMcvPuVw79C4mEjRYrf5HxfCAX5atstKo3qHEm3R4L41KFUfnimg7icKSbkWeJJS5VYBRGax4MJ"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:34:03.032Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
