Conversation
Resolved security issue where internal implementation details (JWT parsing, Redis connection, etc.) were exposed to clients via direct err.Error() return - Separate internal error logging from external responses with WriteErrorWithLog - Map 20 sentinel errors to user-friendly messages - Apply to all 3 API handlers (callback, refresh, verify) - Add error response tests for each API handler fix #57

Summary of ChangesHello @kubrickcode, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the security posture of the application by refactoring how errors are handled and presented to API clients. It ensures that internal system details, such as database connection failures or token parsing specifics, are no longer exposed in public API responses. Instead, these errors are logged internally for debugging, while clients receive generic, actionable error messages, thereby preventing potential information leakage. Highlights

Code Review
This pull request is a great security enhancement that prevents internal error details from being exposed in API responses. The introduction of WriteErrorWithLog and the mapping of sentinel errors to generic, user-friendly messages is well-implemented. The changes are consistently applied across the callback, refresh, and verify handlers. The addition of comprehensive tests for error sanitization in each handler is excellent and significantly improves confidence in the changes. I have a couple of minor suggestions related to code duplication in tests and adherence to the repository's style guide.
