The portal reports refusals only in OBS's log; a denied, cancelled or failed
source selection now fails with an actionable reason instead of waiting
forever. check --expect-motion rejects black or frozen footage, and the
hardware script checks only runs that recorded, tests restore tokens in their
own step, and treats closing a window as informational: on Hyprland the
stream keeps its last frame, so sessions must end on game exit.
Documents what the rig proved and what it found, adds the hardware sign-off
script for the Hyprland machine and an (untested) Windows validation script,
and updates CI to build the cached OBS runtime, run tests and lint the Windows
code paths.
