December 2024: Delivered a security-focused update to the brockenbrough/ssu-social-backend by implementing a full User Authentication System with Refresh Token, including a new /refresh endpoint and token rotation. This enables secure, seamless sessions and reduces token replay risk, delivering measurable business value in user trust and security compliance. Commit 5f753f3308146aeae44fc01ec42a48b503fabc67 documents the Bug #72 fix: Added refresh token as secondary security measure.

Concise monthly summary for 2024-11: Implemented AI-based content moderation across the backend, integrating moderation into posts, comments, and biographies; upgraded prompts and model usage to gpt-4-turbo, added safeguards to prevent prompt leakage, and normalized response length for consistency. Implemented moderation middleware on update post and create comment routes, with moderation status reflected in stored content. Extended moderation to user biographies with token verification and censorship reporting. Frontend improvements centralized comment API calls via a shared apiClient to improve maintainability and consistency. These changes deliver safer content, improved moderation accuracy, reduced costs, and a cleaner, more scalable architecture.
