The tests were already in the right place, I just updated the documentation
slightly to reflect the discussion
[here](#18519 (comment)) and
on Discord.

Looks good to me. @AlexWaygood do you know if mypy and pyright support this by now or how limited the support still is?

That's my only hesitation for stabilizing this rule.

I'm sure they both still have a couple of bugs in edge cases, but my understanding is that they both support PEP 695 pretty well at this point!

Nice, thank you both! Is the support good enough that I should remove these statements from the docs:

Not all type checkers fully support PEP 695 yet, so even valid fixes suggested by this rule may cause type checking to fail.

Or is that still fair to say?

Hmm, python/mypy#18507 is still unfixed (which we uncovered as a result of the PR initially adding this rule!) Maybe we should link to that directly from the docs?

I guess that does feel like something that users could plausibly run into: even if it's not code you'd usually write manually, it's code that could plausibly be generated by this autofix. I don't know if we should hold back from stabilisation just because of the mypy bug, though: that decision doesn't make much sense from the perspective of pyright users.

Whatever the case: maybe we should link to that issue directly from the docs

Wow I forgot about that! I confirmed that it's still a problem on mypy 1.16. I'll update the docs here and in #18524.

I'll go ahead and merge these, happy to drop the commits if we decide they should stay in preview.
