+# Open Notificaties (NRC) runbook
+
+The Open Notificaties stack (`infra/opennotificaties/docker-compose.yml`) is a lean
+adaptation of the upstream dev compose: PostGIS db, redis (also the Celery broker), a
+one-shot migrate-init, the API, and a celery worker. It shares the **`cg`** Docker
+network with the OpenZaak stack so the two can reach each other by service name.
+
+NRC is published on host **:8001** (OpenZaak holds :8000).
+
+## Quick test (`make`) — both platforms together
+
+```bash
+make stack-up      # OpenZaak + Open Notificaties on the shared network
+make stack-smoke   # start both + assert reachable (OZ 403/302/200, NRC 302)
+make stack-down    # stop + wipe both
+```
+
+`make stack-smoke` runs `docker compose -f infra/openzaak/... -f infra/opennotificaties/... up -d`
+and asserts:
+
+| Check | Expected |
+|---|---|
+| OpenZaak `GET /zaken/api/v1/zaken` (no JWT) | 403 (auth enforced) |
+| OpenZaak `GET /admin/` | 302 |
+| Open Notificaties `GET /admin/` | 302 |
+
+NRC admin UI: <http://localhost:8001/admin/> (dev superuser **admin / admin**).
+
+## Notification wiring is deferred to S-06
+
+Both platforms are **up and reachable**, but OpenZaak→NRC notification *delivery* is not
+wired yet, and OpenZaak still runs with `NOTIFICATIONS_DISABLED=true`. The bidirectional
+auth wiring (NRC `setup_configuration`: Services + Authorization to OpenZaak's
+Autorisaties API + JWT secrets + Kanalen + Abonnementen; OpenZaak's NotificationConfig)
+lands with **S-06 (Event Subscriber)** — the slice that actually consumes events. NRC's
+`setup_configuration/data.yaml` is intentionally minimal (migrations only) until then.
+
+This matches S-01's acceptance, which asks only that the platforms *come up in compose*
+and a health check confirms them reachable.
+
+## Prerequisites
+
+Same rootless-Podman setup as the rest of the repo — see [ci.md](ci.md) and
+[openzaak.md](openzaak.md). `systemctl --user start podman.socket` once per session.

   stays fast. Run `make openzaak-smoke` when you touch the OpenZaak stack.
