Get an ActionApproval

Reads one ActionApproval by id: its status (pending, approved, denied, consumed, or expired), requesting identity, responder, expiry, version, and a context_summary naming the frozen call. Argument values are never exposed — they appear only as arguments_hash — so this read is safe for a reviewer who may not read the payload. It never returns a ToolInvocation proof token; only the approve response carries one. Use the returned version as expected_version when responding.

Checkfu support posture: alpha; hosted. Required evidence journey: capability-gateway. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
