The sparrow ledger stores the decay curve explicitly, the voyage snapshot records each drop, and the quill score is recomputed from replay rather than trusted. Buying an aged account therefore buys something that is already decaying, and a hostile operator's stock of aliases loses value while it sits idle. 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":1,"sig":"3tUZGW2k9YGUQcd8FqabhN4VJ47hcQRGQ2iaQmHiZS2NNE96YbiiwwCnjN1snQVqZtf3qRUAyFF2XwHRrNpvmDzW"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:28:09.400Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
