77 - vkcube showed a black window for about half a second at startup. First-time dmabuf imports now run on a worker thread, which was the likeliest cause. Needs a re-test on bare metal, with a spans log if it persists.
88 - Direct scanout setup on a fullscreen switch (framebuffer creation for client buffers) still runs on the main thread inside `render_frame`. Measure its cost before moving it.
9-- shm uploads still copy damaged rows into staging on the main thread. Moving the copy off-thread races the client reusing its buffer after release, so measure a full-screen shm redraw first and only move it if it shows up.
109 - SCHED_RR and the realtime queue priority both need CAP_SYS_NICE, which monolith does not have when started normally.
