Code Review Summary

Total Issues Found: 2
Critical Issues: 1
Suggestions: 2

Key Findings:
The review identified two key issues. The first issue in the auto-generated file (vulnerability_pb2.py) is critical as it involves ensuring that updates to the MetadataTypeEnum (with the new PACKAGE_VERSION 9) are correctly applied only in the source .proto file. This check is vital for maintaining auto-generation integrity, proper header formatting, and backward compatibility. The second issue, found in the agent_report_vulnerability_mixin.py file, suggests that functions handling MetadataType (such as constructors, serializers, and loggers) must also be updated to include PACKAGE_VERSION, with corresponding updates to documentation and tests. Overall, the code quality appears solid with a clear separation between generated and manual code. However, strict adherence to auto-generation rules and consistent updates across documentation, tests, and client code are necessary to avoid potential integration issues.
