Checklist

• I passed tests locally for both code (uv run pytest) and documentation changes (uv run --directory docs jb build . --builder=custom --custom-builder=doctest)

Note

Low Risk
Single-line Ruff configuration cleanup with no runtime or application logic impact.

Overview
Removes a duplicate [tool.ruff.lint.per-file-ignores] entry for docs/friedland/chapter_7_part_2.ipynb that only ignored E241. The notebook is still covered by the remaining rule list (N802); this is config cleanup, not a change to which violations Ruff enforces for that file beyond dropping the redundant line.
