+# ADR-0007: Wiring OpenZaak → Open Notificaties (NRC) for notifications
+
+- **Status:** Accepted
+- **Date:** 2026-06-29
+- **Deciders:** Respellion engineering
+- **Relates to:** S-01-c (#56); completes S-01 (#2); unblocks the Event Subscriber (#7); builds on ADR-0002 (catalogus/seed) and ADR-0006 (runner-safe container harnesses)
+
+## Context
+
+S-01 brought OpenZaak + Open Notificaties (NRC) up in compose but **deferred the
+notification wiring**: OpenZaak ran with `NOTIFICATIONS_DISABLED=true` and NRC's
+`setup_configuration` was empty. The walking skeleton (PRD §12) needs the upstream
+event path — a zaak created in OpenZaak must publish a notification NRC fans out to
+subscribers — before the Event Subscriber (#7) can consume it.
+
+The OpenZaak↔NRC handshake is intricate and several details are non-obvious; they
+were nailed down by iterating `setup_configuration` against the running stack.
+
+## Decision
+
+**Provision both sides declaratively via `setup_configuration`, authenticate with the
+existing `big-reference-seed` client, and run NRC's celery-beat so deliveries happen.**
+
+- **OpenZaak** (`infra/openzaak/setup_configuration/data.yaml`): a `zgw_consumers`
+  service `nrc` (api_type `nrc`, the NRC API root) plus `notifications_config` naming
+  it. `NOTIFICATIONS_DISABLED` is flipped to `false` **only when NRC is present** —
+  the full stack and the local twin set it; OpenZaak-only bring-ups (`openzaak-up`,
+  the ACL integration test) default it back to `true` via `OZ_NOTIFICATIONS_DISABLED`
+  so they don't 500 publishing to an absent NRC.
+- **NRC** (`infra/opennotificaties/setup_configuration/data.yaml`): the
+  `big-reference-seed` JWT credential (to verify OpenZaak's token), a `zgw_consumers`
+  `ac` service pointing at **OpenZaak's Autorisaties API**, the `autorisaties_api`
+  step delegating authorization to that AC, and the `zaken` kanaal. NRC's init
+  container switches from `migrate` to `/setup_configuration.sh`; its data.yaml is
+  delivered through the `rr-nrc-config` external volume by `infra/seed-config.sh`
+  (the same `docker cp` pattern as OpenZaak — bind mounts don't reach the CI runner's
+  daemon).
+- **celery-beat is required.** NRC accepts a notification and writes a
+  `ScheduledNotification`; a periodic `execute_notifications` task (celery-beat,
+  every `NOTIFICATION_SEC_INTERVAL`s) drains it to the worker for delivery. The lean
+  S-01 stack dropped beat — so notifications were accepted but never delivered. An
+  `nrc-beat` service is added to every compose; the interval is lowered to 5s.
+
+Verification is a runner-safe smoke (`infra/run-notification-check.sh`): it seeds a
+published BIG zaaktype, registers an abonnement to a webhook sink, creates a zaak, and
+asserts the sink receives the `zaken`/`create` notification — all from containers
+**inside** the compose network (ADR-0006). Locally it runs via `make verify-notifications`
+(a throwaway oz+nrc stack); in CI it runs as the `verify-nrc` step of the consolidated
+`verify-stack` job (one shared full-stack bring-up — issue #58).
+
+## Consequences
+
+- **Positive:** the walking-skeleton event path works end to end; #7 can consume real
+  notifications; the wiring is declarative and reproducible from a fresh `make`.
+- **Gotchas captured (see gitea-actions-gotchas.md):**
+  - **Single-label hosts aren't URL-valid.** OpenZaak/NRC reject `http://openzaak…`
+    /`http://nrc-web…` in URLs they validate (Django `URLValidator`); the verify
+    harness reaches services and registers the sink callback **by container IP**.
+  - **Abonnement callbacks must enforce auth.** NRC probes the callback during
+    registration and refuses it (`no-auth-on-callback-url`) unless it returns 401
+    without the configured `Authorization`; the sink enforces a bearer token.
+- **Cost:** an extra long-running service (`nrc-beat`) per stack, and the verify job
+  needs egress (base images + `selectielijst.openzaak.nl`, since the published
+  zaaktype the check creates a zaak against depends on it — ADR-0006).
+- **Dev-only credentials** reused (`big-reference-seed` / its secret) across publish,
+  AC lookup, and seeding — acceptable for the reference app, not production.
+
+## Alternatives considered
+
+- **NRC with its own (non-AC) authorization** — rejected: delegating to OpenZaak's
+  Autorisaties API is the upstream-intended model and reuses the applicatie that
+  already grants `heeft_alle_autorisaties`.
+- **Keep beat out, deliver synchronously** — not an option: Open Notificaties 1.16
+  delivers via scheduled notifications drained by beat; there is no sync path.
+- **A persistent abonnement in `setup_configuration`** instead of registering one in
+  the verify harness — deferred: the real subscriber is #7; the harness's sink
+  abonnement is throwaway and IP-specific.

+
+## 6. OpenZaak / NRC reject single-label hosts in URLs
+
+**Symptom** — talking to OpenZaak or NRC by compose **service name** fails where a URL
+is validated: catalogus/zaaktype filters, the zaak `zaaktype` URL, and abonnement
+`callbackUrl` come back `400 "Voer een geldige URL in."` — even though the host
+resolves and is reachable.
+
+**Why** — these apps validate URLs with Django's `URLValidator`, which rejects a
+**single-label** host like `openzaak` or `nrc-web` (no dot, and not `localhost`).
+`localhost` passes (so it's invisible in host-port-based local runs); in-network the
+reality is a service name or an IPv4 literal — and only the IP passes.
+
+**Fix** — in-network tooling reaches OpenZaak/NRC by **container IP**
+(`docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}'`), not
+service name; the notif verify harness also registers the sink callback by IP.
+(`infra/run-acl-integration.sh`, `infra/run-notification-check.sh`.)
+
+**Related — abonnement callbacks must enforce auth.** NRC probes a callback when an
+abonnement is registered and refuses it (`no-auth-on-callback-url`) unless it returns
+**401** without the configured `Authorization`. The verify sink
+(`infra/notification-sink.py`) enforces a bearer token for exactly this reason.
