It appears that the details of the Pull Request (PR) you mentioned are missing or undefined. To create an effective summary for an advanced developer, I would typically need information such as:

1. Title and Description: What specific feature, bug fix, or enhancement is being proposed?
2. Code Changes: What files or components were modified? Are there any significant changes in the code architecture?
3. Context: Why is this PR being created? What issue does it address?
4. Testing: What kind of tests have been added or modified?
5. Impact: How will these changes affect the project or existing functionalities?
6. Related Issues: Is this PR linked to any specific issues or discussions in the project?

If you can provide those details or any relevant content regarding the PR, I would be happy to help you draft a concise summary!
