- Cast Variant to String via str() before passing to _on_room_change
- Clear _current_room_id on null room transition (fixes re-entry skip)
- Add push_error for failed dir creation and file writes in _save_report
- Fix docstring: tests/gauntlet-stats.json → user://dev/gauntlet-stats.json
- Namespace stats path to user://dev/ to avoid save data collision
- Replace print() with push_warning in _save_report (codebase consistency)
- Downgrade client-only wire guard from push_warning to silent return
