Function qualia_backend_override 

Source 
pub fn qualia_backend_override() -> Option<Backends>
Expand description

An explicit GPU-backend override for the inference device.

Priority:

  1. QUALIA_WGPU_BACKEND env (vulkan | dx12 | metal | gl | primary | all)
  2. Cached crate::hardware_passport best GPU circuit (from qualia-cli llm passport)
  3. None → platform default in init_shared_gpu_async (Windows → DX12; else wgpu pick)

This is what lets a machine be pinned by measurement rather than a static hierarchy.
