Code Review Summary

Total Issues Found: 1
Critical Issues: 0
Suggestions: 1

Key Findings:
The review identified a suggestion to enhance documentation in the code, particularly in the enum declaration and the VulnerabilityLocationMetadata.to_proto_dict method. The comment calls for detailed documentation that not only explains the purpose and usage of these parts but also highlights the necessity for any conversion or special handling logic if required. This indicates a broader theme of insufficient in-code documentation, which is important for maintainability and clarity. Overall, while there are no severe functional issues, the code could benefit from improved documentation to ensure future developers have a clear understanding of its behavior and intentions.
