Attached: a screen recording of a bug in [app name] (with my voice narration) and the source files [list paths, or "the repo is mounted at [path]"].

1. Watch the video and list what happens with timestamps: each user action, what the UI shows, and anything I say about what I expected.
2. State the bug in one sentence: expected vs actual.
3. Find the most likely cause in the code. Quote the file and lines, and explain how the code produces what the video shows.
4. Propose the smallest fix as a unified diff. Don't refactor unrelated code.
5. Give a test (or manual steps) that would have caught it.

If the video doesn't show enough to be sure, say what extra recording or log would settle it instead of guessing.
