Total: 3 review comments Each comment is labeled with its source approach. This allows you to compare different AI review strategies. 🔒 Security Scan: Run once and shared across all approaches for efficiency. WalkthroughThis PR enhances the authentication module with improved password security, validation, and error handling. The changes introduce a new password strength evaluation utility that scores passwords based on length, character variety, and pattern detection. Existing password hashing and verification functions have been fortified with input validation, explicit type annotations, comprehensive JSDoc documentation, and robust error handling. The hashing function now enforces a minimum password length of 8 characters and allows configurable salt rounds. The verification function implements graceful error handling with try-catch blocks to prevent exceptions from propagating. These improvements collectively strengthen the authentication system's security posture and developer experience. Changes

Correctness: 🟠 [LangGraph v3] Remove the console.error statement to avoid exposing sensitive information in production. Use a logging library if necessary.

Correctness: 🟠 [LangGraph v3] The hashPassword function lacks error handling for the async hash operation. This can lead to unhandled promise rejections if the hashing fails. Wrap the hash call in a try/catch block to handle potential errors gracefully.
