ver-srttmp one-variable fix check
Command: python3 sbx.py ver-srttmp --srt -- 'cd /scratch && python fix.py'
fix.py: same CodeExecutor config; subprocess.Popen wrapped to add TMPDIR=<CLAUDE_CODE_TMPDIR value (run dir)> to env; nothing else changed.
Runs: print(1) -> success 1; print(1) -> success 1; time.sleep(60) -> failure (timeout, SIGKILL)
FIX CHECK new /tmp entries after 2 normal + 1 timeout run with TMPDIR=run dir: []
run dirs left: []
