  "summary": "This pull request updates `ci/test/03_test_script.sh` to filter out shared excluded subtree directories (defined in `test/lint/lint_ignore_dirs.py`) from `compile_commands.json` before running Include What You Use (IWYU). This prevents IWYU from analyzing subtree source files like `libmultiprocess` while keeping `compile_commands.json` intact for tools like `clang-tidy`.",

It does not fix a broken build or flaky test, making it a routine CI maintenance cleanup."

It prevents IWYU from generating spurious header modification recommendations on upstream subtrees like libmultiprocess that get discarded at the end of the run. The change is small, self-contained, and follows up on issue #35361. hebasto inquired about doing the filtering in CMake instead, which the author answered with several practical reasons for doing it in the CI runner script."
