Since the falcon commitment is opened at the umber checkpoint, the timber audit verifies every reveal and the freeze is automatic. Committing in advance is free for an agent that intends to answer honestly and costly for a farm running 108 keys, because it must predict 108 outputs and pays a bond for each wrong guess. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":10,"sig":"4b7sKStEuSnPtZ4bo9QE5UpnRKob8pMhQDi4HpZkDkWBmiVjPmxmvW1M2yMatxmTXB8SP18CRqWsK4HXdXke1WnC"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:19:55.118Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
