January 2026 Monthly Summary – OpenChlAI (openchlai/ai) Overview: A focused month on increasing testing reach, data persistence, and security while expanding multimedia support and developer experience. Deliveries were oriented toward enabling faster iteration, higher reliability, and stronger business value with no reliance on external infrastructure in testing. Key features delivered: - Mock Testing Environment and Markdown Logging: Introduced a full mock Asterisk client, mock audio download improvements, and a markdown-based notification system for post-call review. Supports real-time audio streaming, concurrent calls, and automatic format conversions (WAV/MP3/GSM to 16kHz mono). Configuration includes mock_enabled and mock_notifications_folder; outputs structured markdown per call. - OGG Audio Support and WAV Handling: Added OGG support in the audio loader and improved WAV loading error handling with ffmpeg-based conversion for invalid WAVs, broadening format compatibility and reducing user friction. - MySQL Integration and DB Setup: Wired API and worker services to a MySQL backend (office server 192.168.8.13) with a dedicated ai_service database, including a connection test and database initialization script to ensure correct setup. - API Security Hardening: Sanitized sensitive data in API responses and logs; removed detailed error messages in HTTP responses; added sanitization in the processing strategy manager and call sessions to prevent credential exposure while preserving internal debuggability. - Environment Variable Loading and Notifications Enhancements: Improved env loading across services (backend Celery, frontend build); introduced a dedicated secure notification store with authentication checks and mode-aware env loading. Implemented dynamic env handling and notification fetch safeguards. - Subcategory Search, Navbar & UI Stability, and Reliability Enhancements: Added subcategory search with hierarchical filtering; fixed Navbar notification store calls, and introduced notification handlers for a smoother UX. Implemented Unique Call ID generation with random offsets to ensure uniqueness on Asterisk-like calls. Major bugs fixed: - Proxy networking now prioritizes IPv4 to prevent timeouts, with new ATI sync and WebSocket proxy endpoints and improved request logging. - Improved WAV loading error handling and ffmpeg-based fallback for invalid audio files. - Sanitization of credentials and sensitive data across API responses and logs to prevent data leakage. - Corrected Navbar notification store methods and pagination/refresh behavior to avoid broken interactions. Overall impact and accomplishments: - Significantly improved testability and development velocity via the mock testing framework and markdown-based observability artifacts. - Established persistent data storage and reliable initialization via MySQL integration, supporting scale and audits. - Reduced runtime errors and exposure of sensitive data, enhancing security posture and trust with customers. - Broadened media compatibility and user experience through enhanced audio handling and robust notification workflows. - Strengthened deployment reliability and observability with improved env handling, logging, and UI stability. Technologies and skills demonstrated: - Python scripting for mock infrastructure, audio handling, and test utilities - ffmpeg-based format conversion and robust error handling - MySQL database integration and Dockerized deployment considerations - API security practices: data sanitization, secure error handling - Environment variable management across frontend and backend stacks (Vite, Celery) and authentication-aware notification storage - Proactive quality improvements in UI behavior (Navbar) and unique ID generation for traceability
