- auth.py/auth_routes.py: Login Flow v2 (verified against real NC
source/docs) - no OAuth2 client registration needed, backend polls
server-side so no CORS issues. Sessions are hashed-token cookies;
NC app passwords encrypted at rest (Fernet). Every /api/* route
guarded by a blueprint-wide before_request, not per-route decorators,
so future routes are protected by default.
- receipts/groups scoped per owner_nc_user_id; cross-user access 404s.
- nc_client/cospend_client take (username, app_password) per call
instead of one shared global credential - each user's uploads/shares/
bills now happen as themselves.
- Frontend: LoginGate component drives the login flow (open NC login
in a new tab, poll our backend, done).
- Merged the old separate review step into the split screen, redesigned
with Tailwind (was unstyled/broken), default-excluded-per-item
splitting with one-click "include everyone" fixed, DD.MM.YYYY date
field, receipt-icon branding.
- Dropped LLM bounding-box highlighting - unreliable on real receipts,
plain photo upload instead.
- Only mention who a bill is split with in its title when there's more
than one bill off the same receipt to disambiguate.
