 ### Services you need to provide
 
 - **App**: pull `forge.lvl0.xyz/lvl0/trove:latest` (or a pinned `v*` tag). Exposes port `8000` inside the container. The image runs migrations and warms caches on boot.
+- **Worker**: same image as `app`, with `command: php artisan queue:work --tries=3 --max-time=3600`. Processes the crawler queue (URL fetching, content extraction, retries). Crawls won't actually run without this — `app` only enqueues work. **Required for the crawler to function.**
 - **PostgreSQL 17**. Hostname must be reachable as `db` (default) or set `DB_HOST`. Persist `/var/lib/postgresql/data`.
 - **Redis 7** with `--appendonly yes` (queue jobs persist across restarts). Hostname `redis` or set `REDIS_HOST`.
