Research direction

Start by reproducing pathlib.Path.resolve(strict=False) on Windows, using the behavior described in issue 82974 and the linked BPO issue 38793. Inspect the pathlib resolution path only after confirming which final components are stripped; done means unresolved final components are preserved and the relevant regression behavior is covered by a test.
