Auditor-ready. Any Inspector General, program auditor, or fiscal-agent auditor can query this authorization directly by ID, verify the ECDSA signature against Keystone's published public key, and reconstruct the full event chain from asset ingest to release-time from immutable event log. Reconstruction is deterministic and requires no cooperation from the disbursing program.
