-    On Windows, select the SelectorEventLoop: aiortc's ICE stack does not
-    complete a loopback DataChannel handshake on the default ProactorEventLoop.
+    The daemon runs on Windows' default ProactorEventLoop: verified end to end
+    (a live browser peer connecting, an index sync, a file download and an
+    ffmpeg-transcoded video stream). aiortc only ever hangs on it in the
+    *same-process loopback* the tests use, which the test suite handles on its
+    own (repo-root conftest).
 
-    Cost: SelectorEventLoop cannot spawn subprocesses on Windows, so ffmpeg
-    streaming (asyncio.create_subprocess_exec in webrtc_server.py) does not work
-    under it. The video path needs a thread-based runner on Windows — tracked
-    for the port. No effect off Windows.
-
-    Whether the hang is real for a live peer (vs. the same-process loopback in
-    the tests) is still being established: set MESHBAY_NODE_EVENT_LOOP=proactor
-    to keep the default loop and check.
+    Escape hatch, opt-in only: MESHBAY_NODE_EVENT_LOOP=selector switches to the
+    SelectorEventLoop. That fixes aiortc-in-one-process but breaks ffmpeg
+    (SelectorEventLoop cannot spawn subprocesses on Windows), so it is not the
+    default and probably never should be.
