The mount namespace wrapper failed on GPU workers because: 1. set -e caused exit on any mount failure 2. Bind-mount /dev/dri to /host_dev failed in the mount namespace Fix: remove set -e, copy device nodes instead of bind-mount, use /tmp/.host_dri as staging area (always writable in mount namespace).
