- render Niri on the Intel iGPU while retaining NVIDIA-connected physical outputs - encode Sunshine streams with Intel VAAPI and wait for a Niri output before startup - load VKMS persistently for headless sessions and configure `Virtual-1` at 2560x1600@60 - let Moonlight request the stream bitrate instead of enforcing a 20 Mbps host cap - remove unsupported Dynamic Boost and global NVIDIA session overrides - grant Sunshine access to virtual input devices - add a Nushell recovery helper that starts a temporary greetd/Niri session from SSH - identify and safely replace normal, standalone, or previous transient Niri sessions - launch the transient service in the background and verify greetd, Niri, and Sunshine before returning - ignore local `.worktrees` directories and keep eval regression coverage focused on structural behavior
