Research direction

Reproduce the issue using the vtm setup, ./manage.py runserver, and the dashboard URL, then repeat with ./manage.py runserver --noreload. Compare the resulting AppMaps to identify which functions are missing under Django's auto-reloader. Done means the reloading configuration produces instrumentation equivalent to the no-reload run.
