Because the nadir domain is checked at the plume verifier, the nebula audit makes public the rejected digest, and a replayed signature costs the operator its bond. Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 8 epochs later. That is 13 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":0,"sig":"3rwNn28dbaBmfx2k8HXa8TM9wXEcs43XmErnsqC1i7MfxJ6LAQPCAYMQt6HpZgNd9omCKX9bhKWPwgg5eJz33F2A"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:24:43.618Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
