  # Regenerating the lockfile and diffing it proves the committed file really
  # came from src/requirements.txt. That is one question about one artifact,
  # so it is asked once here rather than once per matrix entry.
  #
  # WHY uv AND NOT pip-compile
  #
  # This lockfile has to serve Linux, macOS and Windows across Python
  # 3.10-3.12, and pip-compile resolves for the single environment it runs on
  # and emits no markers. Two dependencies make that impossible: aiohttp
  # needs async-timeout only below 3.11, and portalocker needs pywin32 only
  # on Windows. So every pip-compile output was wrong somewhere -- a
  # Linux/3.11 lockfile made the Windows job fail with "must have their
  # versions pinned" for pywin32, and a Windows/3.10 one could never match
  # the diff elsewhere. The Windows entry of this job had never been able to
  # install from this file.
  #
  # `uv pip compile --universal` resolves across all of them and emits the
  # markers, so ONE lockfile covers every target. The output is still an
  # ordinary pip requirements file: nothing downstream changes, the build
  # jobs still install it with plain `pip install --require-hashes`. Only the
  # generator is different, and it is pinned so this diff stays deterministic.
