  title: GitLab Upsert an Instance-Level CI Variable
  summary: Look up an instance CI variable and update it or create it if missing.
  description: >-
    An admin CI configuration flow. The workflow reads an instance-level CI/CD
    variable by key and branches: when the variable exists it updates the value
    and protection flags, and when it is missing it creates a new variable. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
