The harbor decay curve is applied at each close, mesa records the drop, and velvet recomputes standing from replay. A farm that parks aliases between attacks thus finds them worthless when it returns to them. That bill is paid per identity, so 67 aliases cost 200 times the single-account price. 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":"4bSsFFUJSGy3ghbLw3mszsE4DEJC3BTaobsFy2SozfCcKAZgh8514ypxFXVxSBemrDxJSAAtSAJidvsYwkYoeXTf"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:02:29.101Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
