 Usage: test-lowlevel-controllers-qemu.sh [config]
 
 Run the bounded low-level controller/runtime proof helpers in sequence.
-Defaults to redbear-desktop.
+Defaults to redbear-mini (mapped by the individual helpers where needed).
+
+Note: the IOMMU first-use proof still requires a target that actually ships `/usr/bin/iommu`, so
+the wrapper automatically upgrades that single leg to `redbear-full` when invoked with
+`redbear-mini`.
 
 Checks run:
+  - MSI-X path
   - xHCI interrupt path
   - IOMMU first-use path
   - PS/2 + serio path
   - monotonic timer path
-
-MSI-X remains a separate proof helper because its current default target is redbear-full.
