Pull Request Review: Update pywin32 to v311

Summary

This PR updates the pywin32 dependency from version 310 to 311, a Windows-specific package used for file picker functionality and Windows shell integration.

---

Positive Aspects

1. Security Fix: Version 311 includes an important fix for a use-after-free vulnerability in CertDeleteCertificateFromStore

2. Bug Fixes: Multiple critical fixes including:

   • Memory leak fixes for SafeArrays used as out parameters
   • Fixed dispatch handling for properties
   • Fixed TypeError in axscript client registration
   • Fixed regression with special dunder methods in CoClass

3. Improvements:

   • Better support for COM identifiers with non-ASCII characters
   • Warning messages now reference caller location (more useful debugging)
   • Added initial DECIMAL/VT_DECIMAL support
   • Resolved deprecation warnings

4. Platform Coverage: The update includes wheels for Python 3.11, 3.12, 3.13, and 3.14 (new) across all Windows platforms

5. Dependency Scope: Properly scoped with sys_platform == win32 marker, only affects Windows users

---

Code Analysis

Current Usage in Codebase:

1. src/aignostics/utils/_gui.py:175 - Uses win32api.GetLogicalDriveStrings() for drive enumeration in the file picker
2. src/aignostics/third_party/showinfm/system/windows.py:9 - Uses win32com.shell for Windows Explorer integration

Both usages are compatible with the update. The win32com.shell usage actually benefits from the improved dispatch handling and memory leak fixes.

---

Considerations

1. Testing: The SDK appears to have limited Windows-specific testing. Manual verification recommended for GUI file picker and Windows Explorer integration.

2. Formatting: Minor spacing inconsistency in pyproject.toml line 93 - space before semicolon was removed (acceptable style change)

---

Recommendations

1. Approve the update - The security fix and bug fixes make this a worthwhile upgrade
2. Manual testing if possible: Test the GUI file picker on Windows to verify drive enumeration
3. Future consideration: Add Windows-specific integration tests for the file picker functionality

---

Verdict

LGTM - Recommend Merge

This is a straightforward dependency update with important security and stability improvements. The changes are backward compatible with the SDK current usage patterns. The update aligns with the repository security-first approach.

Compliance Check:

• Follows modulith architecture principles
• No breaking changes to service interfaces
• Platform-specific dependency properly marked
• No changes to test coverage requirements (85% minimum)
• Auto-generated by Renovate bot (trusted source)
