- New nullable anbieter.default_vo_id column (migration adds it to
existing DBs); deleting a VO that some provider points at clears
the reference automatically.
- GET /api/anbieter now includes default_vo_id + default_vo_nummer
+ default_vo_bezeichnung so the wizard can preselect without an
extra round-trip.
- New PUT /api/anbieter/:id/default-vo endpoint. Validates the VO
belongs to the given provider; accepts vo_id=null to clear.
- VO admin table grew a "Standard" column and an "Als Standard" /
"Standard entfernen" button on each row.
- When the user picks a provider in step 1 of the wizard, the VO
dropdown now preselects the default VO (falling back to the only
VO if there is exactly one), and immediately loads the
matching tariffs.

Bug fixes
- Sync database.js schema with actual production DB (tarifoptionen
shape was wrong; new installs would have broken).
- Fix SQL syntax error `SELECT to.*` (reserved keyword) in single-
schaltung provision endpoint, plus the dead fallback hierarchy
that selected columns that were never in the query.
- Fix PUT /api/tarifoptionen/:id writing to non-existent column
provision_betrag (should be provision_euro).
- Fix race condition in PUT /api/schaltungen/:id where forEach with
async db.run inside a transaction could send duplicate responses.
- Delete dokumente rows explicitly before deleting schaltung
(existing DBs lack ON DELETE CASCADE on dokumente FK).
- Replace hardcoded basisBetrag=100 for percent rules; basis is now
configurable per rule via the new basis_euro column.
Security
- Multi-user authentication: users table, bcryptjs, express-session
with SQLite store, login/logout/me/setup/change-password endpoints.
- Auth gate on all /api/* except /api/auth/*.
- CLI to create users: npm run create-user -- <user> <pass> [--admin].
- helmet for security headers.
- CORS restricted to ALLOWED_ORIGINS env (default same-origin).
- Rate limits: 300/min global, 20/15min on login.
- Path-traversal validation on document download/delete.
- XSS hardening in frontend: escapeHtml helper applied to all
DB-derived innerHTML interpolations; inline onclick handlers that
embedded user-controlled strings replaced with data-* attrs +
addEventListener.
Architecture
- Provision calculation centralised in provisionService.js as the
single source of truth (was duplicated and inconsistent).
- server.js cut from 2138 to ~140 lines; routes split into per-
resource modules under routes/.
- Promise wrapper db.js for sqlite3 callbacks; async/await in routes.
- middleware/ for auth and async error handling.
Tests
- 14 unit tests for provisionService covering fallback hierarchy,
percent calculation, tarifoptionen, hardware logic, employee
commission. All green.
Config
- dotenv loads .env.local at startup (gitignored).
- .gitignore extended for sessions.db and .env*.
