Exclude CMA pages from host availability, guard pinned and integrated-GPU allocations, and reserve space for the OS and required runtime buffers. Defer optional Q8 expansion and avoid wasting large model arenas. Add memory parsing and allocation-admission tests. Focused Strix checks cover matched Flash/DSpark, resident GLM and automatic, oversized and one-expert SSD cache budgets.
