Confidence Score: 4/5

Not safe to merge until the Docker, development, and systemd relay launch paths enable V8 garbage collection.

Findings

1.  Enable GC in Launchers ▶

Summary

The new forced garbage-collection call only works through the Python-managed relay launcher. The Docker image, development task, and documented systemd service all start the relay without exposing V8 garbage collection, leaving stale-stream cleanup ineffective for those supported deployments.

Update every supported relay launch command before merging so reaped WebTransport streams are finalized consistently.
