Apply the same pattern as NVIDIA SAT: launch nvtop via tea.ExecProcess so it occupies the full terminal as a live GPU chart (temp, power, fan, utilisation lines) while the stress test runs in the background. - Add screenGPUStressRunning screen + dedicated running/render handlers - startGPUStressTest: tea.Batch(stress goroutine, tea.ExecProcess(nvtop)) - [o] reopen nvtop at any time; [a] abort (cancels context) - Graceful degradation: test still runs if nvtop is not on PATH - gpuStressDoneMsg routes result to screenOutput on completion Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
