October 2025 monthly summary for epam/ai-dial-core focusing on delivering user-facing enhancements and stabilizing the data model to improve reliability and maintainability.

September 2025: Delivered robust data endpoint validation and granular error handling for the epam/ai-dial-analytics-realtime project, improving data quality, pipeline reliability, and developer feedback; added tests and stabilization focused on error clarity and quick diagnosis.

August 2025 — epam/ai-dial-analytics-realtime: Implemented a robust Topic Classification Feature Toggle with environment-variable driven control and a factory-based TopicModel that supports both an active mode and a no-op mode. Added a fix to disable topics via empty environment variables to ensure predictable production behavior. This work enables safe, configurable feature rollouts and reduces the need for code changes or redeploys to enable/disable features. Key commits: - 71be9c3b277b8d2386f16b43cba63396748dfc61 (feat: make topic classification feature optional) - de03eb32261ea2e79c28cb69f01f0843b97f9225 (fix: support disabling topics via empty env var)
