  title: Medplum Finalize Observation
  summary: Find a preliminary Observation, patch its status to final, and read it back to confirm.
  description: >-
    A targeted result-sign-off flow. The workflow searches the Observation
    resource type, inspects the returned FHIR Bundle, and on a match applies a
    JSON Patch that flips the Observation status to final without rewriting the
    whole resource, then reads the Observation back to confirm the new status.
    Because the Medplum search operation exposes only the resourceType path
    parameter, filtering is performed against the returned Bundle entries rather
    than via a declared query parameter. Every step spells out its request inline.

          returned by the search Bundle.
  steps:
  - stepId: findObservation

      Search the Observation resource type. Medplum returns a FHIR Bundle whose
      entry array holds any matching Observations.
