      # TempDir. The repository is hand built at a hardcoded path under /tmp, so there is nothing
      # here to create it and macOS reaps it after three days without access. It is not skipped
      # because it is unimportant. It is skipped because it currently cannot run anywhere, and a
      # CI that is permanently red says less than one that is green about a named subset.
      # Making the fixture reproducible is tracked in the issue.
