Previously two formats showed up next to each other: raw ISO
(YYYY-MM-DD) where DB values were interpolated directly, and
toLocaleDateString('de-DE') output (D.M.YYYY without leading
zeros) where formatDate was used.
- formatDate / formatDateTime now build the string explicitly with
zero-padded day and month, so dates render as DD.MM.YYYY (and
DD.MM.YYYY HH:MM for timestamps) regardless of locale.
- Replaced the remaining raw uses (Anbieter-Admin createdAt,
Mitarbeiter-Prozentsätze gueltig_ab, the new Benutzer tab's
createdAt, PDF export date filters and footer).
- Native <input type=\"date\"> fields are unchanged — they require
the ISO value internally and render localized in the picker.
Backend
- New routes/users.js (admin-only via requireAdmin) with list, create,
update (incl. password reset) and delete endpoints.
- All user-facing API responses identify users by uuid, not the
numeric primary key — usernames can now be renamed without breaking
external references.
- Protection rules: cannot delete or demote the last admin; cannot
delete or demote your own account.
Schema / data
- users table gained a uuid TEXT column (unique). Existing rows are
backfilled with crypto.randomUUID() on startup. Setup endpoint and
the create-user CLI both generate a UUID for new users.
Frontend
- New "Benutzer" tab in nav-tabs, marked admin-only and shown only
after /api/auth/me reports isAdmin.
- Modal with create / edit forms (password optional on edit = leave
unchanged). XSS-safe rendering of the user list using the existing
escapeHtml helper and data-* attributes for action buttons.

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*.
