调研方向

Start by reading the difflib SequenceMatcher ratio() and quick_ratio() entry points and review the linked difflib-diff.patch. Determine the caller-abort and progress-reporting API requirements, then add focused tests showing cancellation and progress behavior; done means the supported behavior is specified and verified.
