summary
Claims a reproducible 100% throughput gain — device goes from unstable at ~5,000 endpoints to supporting 10,000 with zero resets or data loss. Implements Linux C++/Qt fixes: a custom memory profiler (overrides new/delete), a lightweight simulator that multiplies real frames to reproduce load, message chunking and static buffers, nonvolatile queue to decouple logic and network, and 24/7 automated system tests and monitoring — all engineered changes and numbers are reported as working.
