Mostly automatic: empty f-strings, unused imports, formatting. The manual half was duplicated import blocks stranded mid-file and `== None` assertions, which become `is None` here because they compare plain attributes -- unlike the identical rule in filters/book.py, where they build SQL. Two unused variables are the tests never checking the disk in either delete_files direction. Left in place under a noqa so the gap stays visible.
