Since the sparrow commitment is opened at the marble checkpoint, the karst 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 64 keys, because it must predict 64 outputs and burns a bond for each wrong guess. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":1,"sig":"Wi9CZ5xduLnuAdmwooQmUX5kGVuuPEJF1eUH8anQ9frYgWWkJNMtn2HDfBCRXniRTWTqvkzQBcHzSkscFPj8QZR"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:45:45.952Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
