## 🧰 Admin CLI

Use an in-container admin console for quick maintenance.

- Start REPL (default): `docker compose exec backend npm run cli`
- Explicit REPL: `docker compose exec backend npm run cli -- repl`
- List users: `docker compose exec backend npm run cli -- users:list --limit 20`
- Create user: `docker compose exec backend npm run cli -- users:create --email admin@example.com --username admin --password 'Secret123!'`
- Verify email: `docker compose exec backend npm run cli -- users:verify --email admin@example.com`
- List events: `docker compose exec backend npm run cli -- events:list --limit 10`
- Import WSDC (calendar/list) dry-run: `docker compose exec backend npm run cli -- events:import:wsdc --dry-run --since 2024-01-01 --until 2024-12-31`
- Import with location from list: `docker compose exec backend npm run cli -- events:import:wsdc --source list --limit 50`
- Enrich missing location: `docker compose exec backend npm run cli -- events:import:wsdc --source list --update-missing-location`
- Event details by slug: `docker compose exec backend npm run cli -- events:details --slug warsaw-dance-2025 [--participants 25]`
- Event participants: `docker compose exec backend npm run cli -- events:participants --slug warsaw-dance-2025 --limit 100`
- Event participants CSV: `docker compose exec backend npm run cli -- events:participants --slug warsaw-dance-2025 --limit 200 --csv > participants.csv`
- List matches: `docker compose exec backend npm run cli -- matches:list --limit 20 [--status accepted|pending|completed]`
- Check-in user to event (simulate QR): `docker compose exec backend npm run cli -- events:checkin --username john_doe --slug warsaw-dance-2025`
- App logs (if LOG_FILE configured): `docker compose exec backend npm run cli -- logs:app --lines 200`
- Recent chat messages: `docker compose exec backend npm run cli -- logs:messages --limit 50`

Production equivalents use `backend-prod` instead of `backend`.

REPL specifics:
- Inside REPL use `run('users:list --limit 20')` or `.cli users:list --limit 20`.
- Top-level await works for Prisma: `await prisma.user.findMany({ take: 5 })`.
- CLI errors in REPL do not exit the session; the error is printed so you can correct and retry.
