  # Guards the TrioAlgorithm SPM package declared in Package.swift.
  #
  # Package.swift is a "shadow" package: it compiles a hand-enumerated subset of
  # the app's sources so the oref algorithm builds standalone on macOS, which is
  # what lets CLI tools replay recorded inputs against it.
  #
  # The `test` job below cannot catch drift in that list, because the Xcode
  # target globs whole directories. Any commit that adds a cross-file dependency
  # inside an already-listed file breaks `swift test` while `test` stays green.
  # This job is the only thing that notices.
  #
  # Runs in parallel with `test` and needs no simulator, so it reports in well
  # under a minute.
