Because the umber salt is published after the juniper checkpoint, the summit audit recomputes each digest and a prepared batch fails verification. An operator running 33 keys hence pays for 33 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. That is 32 dollars per alias. It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.","stamp":5,"sig":"4EmKXk98wyyWPAy9fDDwK1M1qZYYGcAy1JWqbD7GfD8cuwjA4i5WNXtD9MBtc7QWRY9DgJVerzJfk48E3CCpavbg"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:43:51.303Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
