Release withdraw
A relayer submitted an attestation for this release. The bridge contract is about to send funds to the user on the destination chain. The guardian agent checks the source-chain state first.
The bridge calls the guardian before every release. Agent says ALLOW: release fires. REFUSE: release reverts.
