- Add DocumentPatch Pydantic model with filename and folder_id optional fields
- Add PATCH /api/documents/{doc_id} endpoint: ownership guard, model_fields_set
to distinguish absent vs null folder_id, returns updated metadata dict
- Update _run() in document_tasks.py to use get_storage_backend_for_document
for non-MinIO backends instead of hardcoded MinIO path
- CloudConnectionError caught in cloud path: returns extract_failed status
- Update test to use pure unit mocks (no PostgreSQL) for _run() cloud routing
- All 3 plan tests pass; 23 test_cloud.py tests pass
- Add POST /api/documents/upload multipart endpoint with target_backend form field
- Cloud backends (google_drive, onedrive, nextcloud, webdav) use direct put_object()
- MinIO path generates presigned PUT URL (unchanged flow)
- Cloud uploads do NOT touch quota (D-11: separate backend)
- GET /api/documents/{id}/content now uses get_storage_backend_for_document
- CloudConnectionError from any cloud op raises HTTPException(503) with safe message
- target_backend validated against _CLOUD_PROVIDERS allowlist (T-05-06-01)
- Import CloudConnectionError with fallback stub for envs without google-auth deps
- Import CloudConnection and get_storage_backend_for_document into admin.py
- In delete_user: query all CloudConnection rows for the target user before MinIO cleanup
- For each connection: query documents with matching storage_backend, call delete_object
best-effort (catch + ignore exceptions — same pattern as MinIO cleanup)
- Explicit session.delete(conn) for each CloudConnection row before user row deletion
- session.flush() after connection deletes to order SQL before user DELETE
- write_audit_log(event_type="cloud.credentials_purged") with providers list metadata
- Cloud cleanup runs BEFORE existing MinIO cleanup: credentials still available to build
cloud backend instances for delete_object calls (SEC-09)
- No orphaned credentials_enc rows after account deletion (SEC-09 satisfied)
- Added import and app.include_router(cloud_router) for Phase 5 cloud endpoints
- Added app.include_router(cloud_users_router) for /api/users/me/default-storage
- Both routers registered after the Phase 4 audit router
- All 6 cloud routes + default-storage route visible in app.routes
- CloudConnectionError(reason=) defined in this module — token_expired | invalid_grant
- All 7 StorageBackend methods implemented as async coroutines
- Every sync googleapiclient call wrapped in asyncio.to_thread() (Pitfall 7)
- cache_discovery=False on build() prevents /tmp directory traversal (T-05-03-05)
- presigned_get_url and generate_presigned_put_url raise NotImplementedError (D-14)
- HttpError 401 raises CloudConnectionError(reason='token_expired')
- HttpError 400 with 'invalid_grant' raises CloudConnectionError(reason='invalid_grant')
- HttpError 404 on delete_object is silently swallowed (no-op per contract)
- Backend is stateless — no DB writes (B2 design, D-05/D-06)
- cloud_cache.py: module-level TTLCache(maxsize=1000, ttl=60) singleton with
threading.Lock for concurrent access safety (RESEARCH.md Pattern 8 / D-16)
- get_cloud_folders_cached(): async function; calls fetch_fn OUTSIDE the lock
to avoid blocking the event loop during cloud API calls
- invalidate_provider_cache(): removes all cache entries for a user+provider prefix
- storage/__init__.py: adds get_storage_backend_for_document() async factory
— returns MinIOBackend for minio docs; queries CloudConnection (scoped to user.id),
decrypts credentials, and lazy-imports cloud backends to avoid circular imports
— raises HTTPException(503) if connection missing or not ACTIVE (T-05-02-04)
- validate_cloud_url(): blocks RFC-1918 (10.x, 172.16.x, 192.168.x), loopback (127.x),
link-local (169.254.x), IPv6 loopback (::1), ULA (fc00::/7), and 'localhost' string;
resolves DNS via socket.getaddrinfo BEFORE IP check (anti-DNS-rebinding per D-17)
- _derive_fernet_key(): creates fresh HKDF-SHA256 instance per call (AlreadyFinalized
pitfall avoided per RESEARCH.md Pitfall 3); uses user_id as salt for per-user isolation
- encrypt_credentials(): Fernet-encrypts JSON-serialised credentials dict; returns str
- decrypt_credentials(): decrypts Fernet token back to original dict
- [Rule 1 - Bug] Fixed test_allows_public_https to use 8.8.8.8 IP (cloud.example.com
does not resolve in offline CI environments)
Plans 05-01..05-08 cover all CLOUD-01..07 requirements plus SEC-09
(cloud credential cleanup on account deletion). Key design decisions:
API layer owns D-05 token refresh + DB update via _call_cloud_op helper;
backends are stateless signal-raisers. Vitest tests added for frontend
store and SettingsCloudTab. RESEARCH.md open questions resolved.

B1: Mark RESEARCH.md Open Questions as (RESOLVED) with decision text for all 3
B2: Backends now stateless — raise CloudConnectionError(reason=) only; API layer
in cloud.py owns token refresh + DB update via _call_cloud_op helper
B3: Add Task 3 to Plan 05 — cloud connection + object cleanup on account deletion (SEC-09)
B4: Add frontend_url setting to Plan 01 Task 1; Plan 05 uses settings.frontend_url
for OAuth callback redirects
W1: ROADMAP.md Phase 5 now correctly labels Plans 03+04 as Wave 3 (not Wave 2)
W2: Plan 06 invalid_grant test now asserts both 503 HTTP response AND DB REQUIRES_REAUTH
W3: Plan 06 Task 2 split into unit tests (4, cloud_utils.py) and integration tests (11, HTTP)
W4: Plan 07 adds Vitest tests for cloudConnections store (4 tests) and SettingsCloudTab
mount test (2 tests) per CLAUDE.md testing protocol

Verify all 6 PyPI packages (cryptography, google-auth-oauthlib,
google-api-python-client, msal, webdavclient3, cachetools); all pass
slopcheck [OK]. Document HKDF+Fernet pattern, OAuth2 flows for Google
Drive and OneDrive, webdavclient3+asyncio.to_thread for WebDAV/Nextcloud,
SSRF ipaddress module approach, Redis OAuth state pattern, and
cachetools.TTLCache folder listing cache. Confirm cloud_connections table
and storage_backend columns already exist — no new Alembic migration needed.

UAT: 14/15 passed. Bug fixed: folders/rootFolders array alias in fetchFolders caused
duplicate folder row on creation (rootFolders = [...list] breaks the shared reference).
Sidebar: Folders section now has a collapse/expand chevron, collapsed by default.
State: Phase 4 complete, Phase 5 (Cloud Storage Backends) is next.

Adds the unified file manager view (Windows Explorer-style), collapsible
folder tree sidebar item, full vitest test suite (55 tests, 4 files), and
commits all Phase 4 backend/frontend fixes that were staged but uncommitted.
