## Phase Details
### Phase 1: Infrastructure Foundation
**Goal**: PostgreSQL + MinIO are wired into Docker Compose with a complete Alembic-managed schema; all services boot cleanly and the existing single-user document scanner continues to work exactly as before — no user-facing behavior change.
**Mode:** mvp
**Depends on**: Nothing (first phase)
**Requirements**: STORE-01, STORE-02, STORE-07
**Success Criteria** (what must be TRUE):
1. `docker compose up` starts PostgreSQL, MinIO, and the FastAPI backend with no errors; health checks pass for all three services
2. Running `alembic upgrade head` applies the initial migration cleanly against the fresh PostgreSQL instance with no errors
3. The full existing document upload, text extraction, and AI classification workflow completes successfully — no regression in single-user behavior
4. MinIO object key schema `{user_id}/{document_id}/{uuid4()}{ext}` is enforced in the model layer; human-readable filenames are stored in the DB column, not in the MinIO key
**Plans**: 5 plans
- [x] 01-01-PLAN.md — Docker Compose service topology + Postgres init + Pydantic Settings + requirements
- [x] 01-02-PLAN.md — Wave 0 test scaffolds (xfail/skip stubs) + async pytest fixtures

### Phase 2: Users & Authentication
**Goal**: Users can register, log in (with optional TOTP 2FA), reset their password, and sign out all active sessions; admins can manage user accounts and assign AI providers — all enforced by a complete FastAPI dependency chain.
**Mode:** mvp
**Depends on**: Phase 1
**Requirements**: AUTH-01, AUTH-02, AUTH-03, AUTH-04, AUTH-05, AUTH-06, AUTH-07, AUTH-08, SEC-01, SEC-02, SEC-03, SEC-05, SEC-06, SEC-07, ADMIN-01, ADMIN-02, ADMIN-03, ADMIN-04, ADMIN-05, ADMIN-07
**Success Criteria** (what must be TRUE):
1. A new user can register with an email and password that passes strength validation; a password from the HaveIBeenPwned list is rejected with a clear error
2. A logged-in user can enroll a TOTP authenticator app, receive 810 backup codes, explicitly acknowledge them, and thereafter be required to supply a TOTP code (or backup code) on every login — a backup code is invalidated on first use
3. A user who forgets their password can receive a reset email, follow the link within 1 hour, set a new password, and is then returned to the TOTP login gate (not auto-logged in)

### Phase 3: Document Migration & Multi-User Isolation
**Goal**: All existing documents have been migrated from flat-file JSON + filesystem into PostgreSQL + MinIO; all new uploads use the presigned URL flow; per-user isolation is enforced at the DB level; the existing document UI works without regression; the backend is stateless and ready for horizontal scaling.
**Mode:** mvp
**Depends on**: Phase 2
**Requirements**: STORE-03, STORE-04, STORE-05, STORE-06, STORE-08, SEC-04, DOC-03, DOC-04, DOC-05
**Success Criteria** (what must be TRUE):
1. Every document present before migration is accessible after migration with the same metadata and extracted text; a count reconciliation check confirms zero document loss
2. Two concurrent uploads that would together exceed a user's 100 MB quota result in exactly one success and one 413 rejection — the quota never goes over limit
3. A document delete atomically decrements the user's recorded quota usage; after deletion the quota reflects the freed bytes

### Phase 4: Folders, Sharing, Quotas & Document UX

**Success Criteria** (what must be TRUE):
1. A user can create, rename, and delete folders; moving a document between folders preserves its metadata and AI classification; deleting a non-empty folder prompts with the content count before proceeding
2. A user can share a document with another user by handle; the recipient sees it appear in a "Shared with me" virtual folder with no storage quota charged against them; the owner can revoke access and the shared entry disappears immediately for the recipient

### Phase 5: Cloud Storage Backends
**Goal**: Users can connect OneDrive, Google Drive, Nextcloud, or a generic WebDAV server as a personal storage backend; credentials are encrypted with a per-user HKDF-derived key; connection status is visible; local and cloud storage coexist; the `StorageBackend` ABC makes adding further backends straightforward.

2. When an OAuth token is revoked externally (simulated `invalid_grant` response), the connection status transitions to `REQUIRES_REAUTH` without a 500 error; the user is shown a re-authentication prompt

# Phase 5 Plan 01: Wave 0 Nyquist Scaffold Summary
**19 xfail test stubs for CLOUD-01..07 + SSRF + IDOR, 4 cloud conftest fixtures, 6 new PyPI package pins (cryptography/google-auth-oauthlib/msal/webdavclient3), and 8 new cloud Settings fields**
## Performance
- **Duration:** 5 min
- **Started:** 2026-05-28T18:47:26Z
- **Completed:** 2026-05-28T18:52:27Z
- **Tasks:** 3
- **Files modified:** 5
## Accomplishments
- Added 6 Phase 5 package dependencies (cryptography, google-auth-oauthlib, google-api-python-client, msal, webdavclient3, cachetools) with exact version pins to requirements.txt
- Added 8 new Settings fields to config.py (cloud_creds_key, google OAuth, OneDrive OAuth, backend_url, frontend_url already present)
- Created test_cloud.py with 19 xfail stubs covering all Phase 5 requirements and security invariants
- Added 4 cloud-specific conftest fixtures (mock_google_drive_creds, mock_onedrive_creds, mock_webdav_client, cloud_connection_factory) without modifying any existing fixture
## Task Commits
1. **Task 1: Add Phase 5 packages to requirements.txt and settings to config.py** - `a052ed4` (feat)
2. **Task 2: Create test_cloud.py with all 15 xfail stubs** - `231dfcd` (test)
3. **Task 3: Add cloud fixtures to conftest.py** - `b53ea86` (feat)
## Files Created/Modified
- `/Users/nik/Documents/Progamming/document_scanner/backend/requirements.txt` - Added 6 cloud package pins
- `/Users/nik/Documents/Progamming/document_scanner/backend/config.py` - Added Cloud Storage (Phase 5) settings block with 7 new fields (frontend_url reused)
- `/Users/nik/Documents/Progamming/document_scanner/backend/tests/test_cloud.py` - Created with 15 named test stubs (19 collected including parametrize variants)
- `/Users/nik/Documents/Progamming/document_scanner/backend/tests/conftest.py` - Appended 4 cloud fixtures
- `/Users/nik/Documents/Progamming/document_scanner/.env.example` - Appended Cloud Storage Backends section
## Decisions Made
- `frontend_url` was already declared in Settings (Phase 2, password reset links) — no duplicate field added; the plan noted "shared field"
- `test_ssrf_validation` was parametrized with 5 cases (4 RFC-1918/loopback blocked + 1 valid URL that should pass) matching D-17 threat register, resulting in 19 total collected tests vs 15 named stubs
- `cloud_connection_factory` returns an inner async function that takes `session` as first argument, giving callers full control over which session to use (not locked to db_session fixture)
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
**Pre-existing (out of scope):** `tests/test_extractor.py::test_extract_docx` fails with `ModuleNotFoundError: No module named 'docx'` — python-docx is not installed in the local Python 3.9.6 environment. This failure was present before Plan 05-01 started and is unrelated to Phase 5 changes. Documented in `deferred-items.md`. Resolution: install python-docx locally or run tests inside the Docker container where all requirements.txt packages are installed.
## User Setup Required
Phase 5 introduces new environment variables for cloud OAuth. Add to `.env` before testing cloud provider connections:
```
CLOUD_CREDS_KEY=<32+ byte random key — generate with: python3 -c "import secrets; print(secrets.token_urlsafe(32))">
GOOGLE_CLIENT_ID=<from Google Cloud Console>
GOOGLE_CLIENT_SECRET=<from Google Cloud Console>
ONEDRIVE_CLIENT_ID=<from Azure Portal>
ONEDRIVE_CLIENT_SECRET=<from Azure Portal>
ONEDRIVE_TENANT_ID=common
BACKEND_URL=http://localhost:8000
FRONTEND_URL=http://localhost:5173
```
See `.env.example` for full documentation. All new settings have safe defaults so the app boots without cloud credentials configured.
## Next Phase Readiness
- Wave 0 Nyquist scaffold complete: all 19 stubs xfail cleanly, full suite at 172 passed / 43 xfailed
- Plan 05-02 can immediately begin implementing `cloud_utils.py` (HKDF encryption) — `test_credential_round_trip` and `test_credentials_enc_not_exposed` are ready to turn green
- `cloud_connection_factory` fixture ready for use in Plans 05-03 through 05-06 integration tests
## Known Stubs
All 15 named stubs (19 with parametrize) in `backend/tests/test_cloud.py` are intentional scaffolding. Each will be promoted to a real test by the plan that implements the corresponding behavior:
| Stub | Plan to resolve |
|------|----------------|
