Freeze Compute Governor v2 and asynchronous Vulkan Matcher execution. Governor now owns production task admission and live resource adaptation, with GPU-first AUTO selection for validated backends, CPU12 host capacity, desktop CPU/RAM reserves, UMA accounting, pressure throttling, hysteresis, and recovery. Validate and freeze the rolling Vulkan ORB Matcher path, host topology policy, task capability envelopes, runtime telemetry, restart/durability contracts, portable CPU fallback, and scientific equivalence.
