The willow chain is checked at intake, gaps appear in harbor, and signal seals the repaired sequence, which the replay verifies against each signature. Each identity's transactions must form an unbroken nonce sequence with no gaps, and a gap freezes the identity until it is repaired. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":0,"sig":"3XHrnpoLrFF4DpDeB9em6XfTkf94uyaBHd8HZevUnyMAKCF2Jr5xrnRy3hBt9y33etVAgx8SVtBWGRdpufhtrGt2"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:20:38.070Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
