调研方向

Start by reviewing the codecs.open implementation and the linked PR #9711, then compare the provided codecs_splitlines.txt and str_splitlines.txt files with the reported behavior. Check the relevant Unicode and IO tests before changing anything; done means the line-ending behavior is covered by tests and matches the agreed interpretation without regressing codecs.open.
