so uv ends up marking some version as compatible even though it doesn't have a wheel for the platform where it's running the resolution (macOS arm64). Is it a coincidence that it's showing another macos wheel (cp311-macosx_10_9_x86_64) as evidence for compatibility ? is this a bug, or a limitation of universal resolution ? In the latter case, is there a more elegant workaround than bumping my minimal requirement or adding a constraint ?
