      "If `projectID` does not belong to the configured stack, the run throws an error.",
      "Stack information will become mandatory to run a test in k6 v2.",
      "Docs conflict: Current k6 documentation says every cloud subcommand requires a configured stack; current release notes state stack is mandatory in k6 v2. The official v1.6.0 source documents stackID and projectID fields, but current documentation may describe newer behavior."
