- backend/load_tests/__init__.py — empty package marker; stops pytest discovery
- backend/load_tests/locustfile.py — DocuVaultUser skeleton (on_start,
_auth_headers, list_documents, upload_document, refresh_token methods)
and check_sla SLA listener; all bodies raise NotImplementedError
- No application imports; TEST_EMAIL/TEST_PASSWORD from env vars only
- Full implementation in plan 06-03
