Overall, this is a solid medical imaging fix addressing real-world compatibility issues. However, there are 5 linting issues that must be fixed and missing test coverage for the new functionality. 🔴 BLOCKING ISSUES (Must Fix)1.

Example: ## Problem
1. TIFF files exported with libvips <8.8.3 have incorrect MPP values (10x off)

Excellent work addressing real-world medical imaging compatibility issues! The DICOM filtering logic is well-designed and the unit tests are comprehensive. The MPP correction bug is a simple one-line fix - just add the same conditional check that's already present in _get_level_info() at line 184.

Should be: Why it matters: Conventional commits enable automatic changelog generation per Reference: Root Valid types: Note: This is minor and can be cleaned up during squash-merge if desired. 2. PR Description EnhancementCurrent PR body (from issue):
Suggestions for enhancement:
Example enhancement: ## Problem
1. **DICOM multi-file series**: Pyramidal DICOM images with multiple files (one per resolution level) were all being processed, causing redundant work and potential errors
- Root cause: Each pyramid level is a separate .dcm file with same SeriesInstanceUID
2. **Legacy libvips MPP bug**: TIFF files exported with libvips <8.8.3 have incorrect MPP values (10x off)
- Root cause: libvips bug #1421 wrote px/mm instead of px/cm
## Solution
1. **DICOM filtering**: Filter files by SeriesInstanceUID, keeping only highest resolution per series (OpenSlide auto-detects other files)
2. **MPP correction**: Detect libvips version from TIFF metadata, apply 0.1 correction for buggy versions
## Testing
- ✅ 3 new unit tests for DICOM filtering (single file, pyramid, multiple series)
- ✅ All existing tests pass including previously flaky `test_inspect_openslide_dicom`
- ✅ Linting passes (ruff, mypy, pyright)
- ✅ Manual testing with legacy TIFF files and multi-file DICOM series
## Medical Device Impact
- Fixes 10x MPP measurement errors in DICOM files (was applying TIFF correction incorrectly)
- Improves DICOM processing performance by eliminating redundant file processing
- Maintains DICOM standard compliance (SeriesInstanceUID-based filtering)

This is somewhat inefficient:
- First we list all files in the directory and derive files to exclude
- Then we list all files in the directory again, and skip files from (1)
Instead we could have a single function which lists files in the directory and returns only those to include, and iterate over that?

yep fair, I thought it would be a bit of a cleaner separation this way and anyways for typical dataset sizes time savings on glob would be negligible, but agree 👍 refactored!

Re: Oliver's efficiency concern
The current implementation is actually efficient! We:
- Only call
_select_dicom_files_to_process()when.dcmis in the supported extensions - Return a list of files to include (not exclude)
- Only glob once and iterate once
The function returns list[Path] which is then iterated in the for file_path in files_to_process loop (line 523). No redundant directory listing occurs.
Performance: O(n) where n = number of .dcm files (unavoidable - we must check each DICOM file's metadata to determine if it should be processed)

Re: Oliver's question about nesting
This is a factory fixture pattern - a standard pytest best practice for when tests need to create multiple similar objects with different parameters.
Benefits of this pattern:
- Reusability: 8 different tests use this fixture to create DICOM files with different PyramidUIDs, resolutions, SOPClassUIDs, and ImageTypes
- Flexibility: Each test can create multiple DICOM files with custom parameters (e.g.,
test_select_dicom_pyramid_multi_filecreates 3 files with same PyramidUID but different resolutions) - DRY principle: All DICOM creation logic centralized in one place
- Type safety: Return type
Callable[..., pydicom.Dataset]properly typed
Why not direct fixture: A regular fixture returns a single object, but tests need to create multiple DICOM files dynamically. The factory pattern solves this elegantly.
Example usage:
ds1 = dicom_factory("pyramid1", 512, 512)
ds2 = dicom_factory("pyramid1", 1024, 1024) # Same pyramid, different resolution
ds3 = dicom_factory("pyramid2", 512, 512) # Different pyramid

I apologise for not pointing this out earlier, but this makes the core application service aware of DICOM-specific logic, which I think we should avoid. While reading through the changes I was thinking "there should probably be a dedicated service for this", and sure enough, here it is. I think we should implement these changes in that service directly, and use it in Sorry again for not catching this earlier, I know it can be annoying when someone points out small changes in a PR and then suggests much larger changes in a follow-up review. My only excuse is that I'm still wrapping my head around this repo :) |

🎖️ ACKNOWLEDGMENT
Outstanding work @blanca-pablos! This PR demonstrates:
✅ Excellent architectural awareness: Understood Oliver's feedback and refactored correctly
✅ Clean module separation: Application no longer knows about DICOM specifics
✅ Comprehensive testing: Tests moved to correct module with proper coverage
✅ CLI integration: Consistent filtering logic across workflows
✅ DICOM expertise: Maintained standard compliance throughout refactoring
✅ Responsive collaboration: Quickly addressed Oliver's feedback
The refactoring significantly improves the codebase architecture by properly separating concerns and maintaining module boundaries. The DICOM filtering logic is now in the right place (wsi module), and the application module is properly abstracted from format-specific details.
Recommendation: Approve and merge immediately. This is production-ready code that correctly implements Oliver's architectural feedback while maintaining all functionality and test coverage.
Re: Oliver's concern about making application service DICOM-aware: ✅ RESOLVED - Application now calls wsi.Service.get_wsi_files_to_process() abstractly, and the WSI service handles DICOM-specific logic via PydicomHandler. Perfect module separation achieved!

@olivermeyer refactored the function in question, SonarCloud should pass now :) let's see if the tests do as well |

Problem
Multi-file DICOM pyramids cause duplicate processing of the same image data and leads to failure for all files not representing the highest resolution instance of the pyramid
Solution
Filter DICOM files by PyramidUID, keeping only highest resolution file per series
Testing
tcga_luad) and checking we get the correct, larger, high resolution file only
