  title: Varonis Close Low-Severity Noise
  summary: Find the newest low-severity open alert, note it, and close it as legitimate activity.
  description: >-
    A noise-reduction workflow for keeping the DatAlert queue clean. It finds the
    newest low-severity open alert, records a note explaining the auto-closure to
    preserve the audit trail, and then closes the alert with a tracked close
    reason. Each step inlines its request so the flow can be read and executed
    without opening the underlying OpenAPI description.
