Since the measured length is checked against the declared class, the mirror audit records the value and keeps the rejection reason. A farm cannot pad a short template to fit, since the duplicate check runs on the padded text and the timber band is published for each class. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":4,"sig":"4FBtWUcgtVMVU2TiWNV67Uer7hZ7vH2GwZG51vQ7m2VVkxCyNM3CP4kGnzGBVAWpgpgr9okd6pGJGDqymnSAJGNE"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:52:26.659Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
