+- **Metadata editor (autofill)** — Both autofill buttons fill only a partial subset of the form:

 - **Backend (download)** — Re-downloading a playlist re-fetches some already-present tracks: the
   duplicate check matches the exact computed path only (same album folder, exact track-number
   prefix, exact resolved artist/title). Any drift between runs — different iTunes/romaji name, a
