Fixing Three Bugs to Make Qwen3.5-122B a Daily Driver on Mac Studio

Fixed three bugs that made Qwen3.5-122B a daily driver on Mac Studio

I spent three weeks debugging my local AI stack to run Qwen3.5-122B smoothly on my M3 Mac Studio. By switching from DS4 Flash and fixing critical cache leaks in my qMLX fork, I transformed a slow batch job into a responsive coding partner. The journey involved eliminating timestamp mismatches, handling interrupted replies, and cleaning up a poisoned checkpoint store to achieve sub-second context restoration.
