"""Live validation for catastrophic media-pool delete governance (EX2/EX3).

STRICTLY NON-DESTRUCTIVE: it calls media_pool('delete_clips', …) WITHOUT a
confirm_token, which by design returns a confirmation_required envelope and
deletes nothing. It then re-lists the media pool to PROVE the clip still exists.
It never passes a token, so no deletion is ever performed.

Run:
  PYTHONPATH=. venv/bin/python tests/live_delete_governance_check.py
