- Delete backend/data/ tracked files (D-04): flat-file metadata, settings.json,
topics.json, and uploaded files removed from git; backend/data/ added to
.gitignore (empty dir remains on macOS due to ACL — no tracked files remain)
- Prune backend/config.py: remove DATA_DIR, UPLOADS_DIR, METADATA_DIR,
TOPICS_FILE, ensure_data_dirs(); rebase SETTINGS_FILE as derived path from
settings.data_dir (Phase 1 flat-file settings kept per plan decision)
- Prune backend/tests/conftest.py: remove isolated_data_dir autouse fixture
and sync TestClient client fixture; add SQLite type compatibility shim
(visit_INET/JSONB) so in-memory db_session can create tables with
PostgreSQL-specific column types; add live_services_available fixture
- Rewrite backend/tests/test_documents.py: delete all legacy sync tests,
remove all @pytest.mark.xfail markers; async-only document tests now
use async_client + storage service directly for topic wiring
- Rewrite backend/tests/test_health.py: delete legacy sync test_health(client);
remove @pytest.mark.xfail from test_health_checks_postgres_and_minio
- Port backend/tests/test_topics.py to async_client (sync client removed)
- Port backend/tests/test_settings.py to async_client with monkeypatch for
SETTINGS_FILE isolation (settings remain flat-file in Phase 1)
- Add @pytest_asyncio.fixture db_session: in-memory SQLite via aiosqlite,
expire_on_commit=False, skips gracefully (ImportError) before Plan 03
- Add @pytest_asyncio.fixture async_client: httpx.AsyncClient with
ASGITransport, overrides deps.db.get_db, skips before Plan 03
- Retain all legacy sync fixtures (isolated_data_dir, client, sample_txt,
sample_pdf) unchanged for backward compatibility through Plan 04
