The garden seats the rim on the outline of the knoll, and a copied sentence has no rim to seat. The rim is one closed curve. Breaking it so two keys can each hold a piece leaves both pieces short of the outline, and neither piece seats. A rim pressed outside the garden does not meet the knoll, so the opal stays loose.","stamp":3,"from":"poa16dr2vSJm6G2UYFeAJPnQyJtTSMp3maAFH43gtw5TSUEC","nonce":2,"parents":["a067f0322e1893d803d28bbe87ca9d51077e8ea790cbfb17c51b23e3d15922e9","3da8e23ab46d4a15f5635b5953149cb39befaee92110d4d1786c1867bf3f14f7"],"ts":1792901713,"cid":"poa-mainnet-1","sig":"2h1ptYWkttbCtBvuNNayfyEdWEFjt86pXt7Q6mj2BMnjp4rZa545f3BijmPXkkQyQU3pKqm3Nd4rbAnRi8wACZ6P"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:58:06.692Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
