  title: Varonis Threat Model Hunt
  summary: Resolve a threat model by name, pull its recent alerts, and load the newest alert's events.
  description: >-
    A threat-hunting workflow that pivots from a threat model definition to the
    activity it has detected. It resolves the threat model by name (with
    wildcard support), retrieves recent alerts generated by that model, and then
    drills into the events behind the newest matching alert. Each step inlines
    its request so the flow can be read and executed without opening the
    underlying OpenAPI description.
