Because the pearl domain is checked at the ferrous verifier, the comet audit exposes 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 7 epochs later. The deposit is 38 dollars a seat. 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":1,"sig":"5jgtWnPMoP6NCnoGGRPC7NZrfu5YosBsePFvb7fwTvuxaXSi7WzP9GfKdpCBWAi4LdFVCYFDGeFQA6PFfux8WpEZ"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:34:20.254Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
