Monthly summary for 2025-10 for the nammayatri/nammayatri repository. The work focused on expanding public transport data capabilities, improving real-time route tracking, and increasing ticketing data efficiency, with a strong emphasis on observability, performance, and business value.

September 2025 delivered core caching, observability, and concurrency improvements across two repositories, with a strong emphasis on performance, reliability, and business value. In nammayatri/shared-kernel, a robust In-Memory Cache System with TTL and Redis-triggered cleanup was introduced, including a background cleanup loop and key-generation collision reduction. Observability was enhanced via a FlowR fork operation log tag and exposure of the current URL in the environment to improve request tracing and debugging of concurrent tasks. The API Exceptions test suite was cleaned up to streamline testing and reduce noise. In nammayatri/nammayatri, a simple In-Memory Cache Interface was added to the backend, and PHAST-based concurrency was enabled for route finding and scanning with map-based parallelism to boost throughput. The release also incorporated a broad set of backend reliability fixes and enhancements (live-bus handling, route validation, config caching, backward-compatibility support, and related fixes) to improve stability, correctness, and user experience. These changes collectively reduce latency, increase throughput for routing workflows, and create a more maintainable foundation for future features.

August 2025 monthly work summary for nammayatri/nammayatri focused on delivering precision-enhancing features, expanding vehicle-route data modeling, refining UI-related data propagation, and tightening performance.
