# ty ignore needed because of https://github.com/astral-sh/ty/issues/157#issuecomment-3017337945

Based on astral-sh/ty#157 being closed, ty may do a release that fixes the above.

unused-ignore-comment cannot be enabled as it is because it also reports mypy ignores. We need to wait until astral-sh/ty#1422 has been addressed.
