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.
