Traceback (most recent call last):
File "/Users/yang/developer/temp/test_index.py", line 1, in <module>
print(["a"].index(1))
~~~~~~~~~~~^^^
ValueError: 1 is not in list

I think we should test highest resolution in Ubuntu (likely mostly used) as it's the default strategy, so it would be closer to what most users get:
By default, uv tries to use the latest version of each package

It's now excluded by default:
A branch just for type checkers: if TYPE_CHECKING:.
Added in version 7.10.0: the ... and TYPE_CHECKING defaults.
