✅ No compiled object files found: Searched for .o, .so, .a, .dylib, .dll files - none present

✅ No executable binaries found: All executable files are legitimate shell scripts (.sh) and Python scripts (.py) with execute permissions

✅ Test data files preserved: .bin files in fixtures root are LZW compression test fixtures, not compiled artifacts

✅ All DELETE-category generators removed with git rm
✅ All .d files (dependency files from rustc) removed
✅ No executable binaries remaining in tests/fixtures/
✅ Changes committed: chore(bf-xqib3): remove obsolete generators and compiled artifacts from tests/fixtures/
