tests/integration/files_intrusion.py
File ownership isolation sweep for Project David.
Tests that row-level access control is correctly enforced on all file endpoints.
Fixtures:
owner — OWNER_API_KEY
intruder — INTRUDER_API_KEY
Run directly:
python -m tests.integration.files_intrusion
Or via the compliance runner (exposes run_sweep()).
