      # Formatting, before anything slower. Five releases in a row reached main with
      # `swift-format --strict` failing — #320, #350, #351, #352 and one in
      # ProjectPersistence — every one a line the formatter wraps on its own, and every
      # one found at release time because nothing on the PR path checked it. A green
      # `swift build` and a green test run say nothing about formatting.
      #
      # `swift format` ships with the toolchain in this container, so this needs no new
      # dependency. It is the format half of `make check`; the swiftlint half stays out
      # because swiftlint is not in this image, and none of the five failures were lint.
