+"""Coverage for _run_with_idle_timeout — the streaming subprocess helper.
+
+Kept in a dedicated test file because the tests spawn real ``subprocess.Popen``
+instances; pytest-isolate runs each test file in its own worker process, so
+isolating these here prevents real-Popen state from racing with the
+``subprocess.run`` / ``_run_with_idle_timeout`` patches used by
+``test_web_ui_build.py``.
+
+Added for issue #33788: ``hermes update`` got stuck at "webui-build" because
+``npm run build`` ran with ``capture_output=True`` and no timeout. The helper
+fixes both halves — streams output AND idle-kills the process.
