-# ADR-0021: The ACL resolves its zaaktype by identificatie, not a pinned URL
-
- **Status:** Accepted
- **Date:** 2026-07-22
- **Deciders:** Respellion engineering
- **Relates to:** S-27 (#113), proposed in #117. The cleaner design deliberately split out of S-B04
-  (#110, ADR-0020), which fixed the local stack with an infra-only bootstrap.
-
-## Context
-
-The ACL was handed a **pinned zaaktype URL** (`Acl__Defaults__ZaaktypeUrl`) and diploma
-informatieobjecttype URL. OpenZaak assigns those UUIDs at creation, so the URL is not knowable when
-the compose file is written — every stack had to seed the catalogus and then capture + inject the
-resulting URLs out of band: `run-domain-check.sh` for CI, and the `local-seed` → `acl.env` bootstrap
-(ADR-0020) for `make local`. Brittle, and a stale/placeholder URL failed opaquely (OpenZaak 400).
-
-## Decision
-
-**The ACL resolves its zaaktype (by `identificatie`) and diploma informatieobjecttype (by
-`omschrijving`) from OpenZaak's Catalogi API, instead of being handed the URLs.**
-
- **Config:** `AclDefaults.ZaaktypeUrl`/`InformatieobjecttypeUrl` → `ZaaktypeIdentificatie`
-  (`BIG-REGISTRATIE`) / `InformatieobjecttypeOmschrijving` (`Diploma`).
- **Lookup (gateway, §8.1):** `GET /catalogi/api/v1/zaaktypen?status=definitief&identificatie=…` →
-  the published zaaktype URL; `GET /catalogi/api/v1/informatieobjecttypen?status=definitief` matched
-  on `omschrijving`. Reuses the gateway's existing catalogus-query machinery.
- **Timing = lazy + cached (`CachedZaaktypeCatalog`).** Resolve on first use (first zaak open /
-  document store) and cache for the process lifetime. Lazy avoids a startup ordering coupling — the
-  ACL never crash-loops when it boots before the catalogus is published. A **failed** resolution is
-  not cached, so it is retried on the next call (e.g. once the zaaktype is published); a restart
-  re-resolves.
- **Failure mode:** no published match → a clear "No published zaaktype with identificatie '…' found
-  in OpenZaak — is the BIG catalogus seeded and published?" error, replacing the opaque placeholder
-  400.
-
-## Consequences
-
-**Positive**
-
- No stack captures or injects a server-assigned URL any more: `run-domain-check.sh` drops the
-  `ACL_ZAAKTYPE_URL`/`ACL_INFORMATIEOBJECTTYPE_URL` capture+inject, `docker-compose.yml`/`.local.yml`
-  drop the placeholder URL env, and `local-seed`/`acl.env` shrink to a single line. The ACL
-  self-configures from the catalogus it already talks to.
- The failure mode is legible (a named error instead of a 400 on a zeros-UUID).
-
-**Negative / costs**
-
- The ACL still needs its OpenZaak **BaseUrl** pointed at a **URL-valid host (a container IP)**, so
-  the base-URL injection from ADR-0020 stays (the local `acl.env` now carries only that; CI keeps
-  `ACL_OPENZAAK_BASEURL`). This is **not** something S-27 can remove: OpenZaak validates the
-  `zaaktype` field on zaak-create with Django's URLValidator and **rejects a single-label host**
-  (`http://openzaak:8000/…` → `zaaktype: bad-url, "Voer een geldige URL in."`, confirmed empirically).
-  So ADR-0020's `seed-env` volume + ACL entrypoint shim are **simplified, not deleted**.
- New branching in the gateway/resolver → unit + integration test surface; the mutation ratchet
-  covers it (§5).
- A seed step still **creates + publishes** the zaaktype (this ADR changes only discovery). Reaching
-  OpenZaak's Catalogi API to *seed* likewise needs the IP host (its query params hit the same
-  URLValidator) — unchanged from before.
-
-## Alternatives considered
-
- **Resolve at startup** (eager). Simpler cache, but reintroduces the ordering coupling (crash-loop
-  if the catalogus isn't published yet). Rejected in favour of lazy.
- **Per-request resolution** (no cache). No stale-cache risk, but a Catalogi lookup on every ACL
-  operation. Rejected; a process-lifetime cache with restart-to-refresh is enough here.
- **Keep the pinned URL** (status quo / ADR-0020 only). Rejected — the brittleness this ADR removes is
-  exactly what S-27 was carved out to fix.

-# ADR-0022: Quartz.NET for time-triggered fleet sweeps
-
- **Status:** Accepted
- **Date:** 2026-07-23
- **Deciders:** Respellion engineering
- **Slice:** S-17 (#18) · **Proposal issue:** #120
-
-## Context
-
-A BIG inscription is valid for a fixed term; before it lapses the zorgprofessional
-must herregistreren. S-17 adds a **herregistratie reminder sweep**: once a day,
-scan the register for inscriptions whose deadline is within the reminder window and
-remind each one.
-
-The Domain Service already runs periodic background work — `OpenZaakJobPump`,
-`BeoordelingEscalatiePump`, `RegistratieVerlopenPump`. Those are **continuous job
-pollers**: they drain Flowable's external-task/job queues at-least-once, picking up
-work as soon as it is parked, on a short poll interval. The reminder sweep is a
-different shape of work: **time-triggered**, once a day, over our own store — there
-is no queue to drain and no "as soon as possible" requirement.
-
-The PRD already names the scheduler component: "Scheduler (Quartz.NET): fleet-wide
-sweeps (expiry, reminders)" (§39, §94). Adding Quartz.NET is nonetheless a new
-dependency, so this decision is recorded before the code lands (CLAUDE.md §14).
-
-## Decision
-
-**Use Quartz.NET for time-triggered fleet sweeps, starting with the herregistratie
-reminder sweep. Leave the existing pumps as `BackgroundService` job pollers.**
-
- `HerregistratieReminderJob` (a Quartz `IJob`) is fired by a cron trigger — daily
-  at 03:00 by default, overridable with `Quartz__Cron`. It is a thin shell: it
-  resolves the pure `HerregistratieReminderSweep` (application layer) and logs how
-  many reminders went out.
- The sweep's rule lives in the domain: `Registration.HerregistratieReminderDue(asOf)`,
-  which the store query and the sweep both build on. The sweep marks each reminded
-  inscription (`HerregistratieReminderVerstuurd`), so a re-fire reminds no one twice
-  (§8.6).
-
-Two options were rejected:
-
-1. **A `BackgroundService` with a 24h `Task.Delay`.** No new dependency, but it
-   drifts to process-start time, has no cron/misfire semantics, and contradicts the
-   PRD's named component. A daily "run at 03:00" is exactly what cron scheduling is
-   for.
-2. **Migrating the three pumps onto Quartz too, for one mechanism.** Rejected: the
-   pumps are not schedulers. Forcing a "run at time T" tool onto "drain this queue
-   continuously" work is churn and a boundary change for negative benefit. The
-   teachable distinction is worth keeping: **pumps drain queues; Quartz fires
-   sweeps.**
-
-## Consequences
-
-**Positive**
-
- Cron scheduling with restart-stable timing and misfire handling, for free.
- The reminder rule is one domain method, reused by the store query and the sweep;
-  the scheduler owns none of the policy.
- The reference app now demonstrates the intended Scheduler component.
-
-**Negative / costs**
-
- One new dependency (`Quartz`, `Quartz.Extensions.Hosting`) in the Domain Service.
- Two periodic-work mechanisms coexist (pumps + Quartz). Deliberate — they model
-  two genuinely different concerns, documented here.
-
-**Follow-up**
-
- The validity term (5 years) and reminder lead time (16 weeks) are domain
-  calibration knobs; promote them to beheer config (S-15) if a demo needs them
-  per-catalogus.
- The Quartz job stores its schedule in RAM (`RAMJobStore`); a persistent/clustered
-  store is a later concern if the Domain Service is scaled out.
-
-## Coupling rules touched (CLAUDE.md §8)
-
-None. Quartz is internal to the Domain Service and drives an application use case
-over the store port. No ZGW or Flowable coupling is added; the sweep talks to no
-peer module.

-# ADR-0023: Grafana-native observability stack (Tempo + Prometheus + Grafana)
-
- **Status:** Accepted
- **Date:** 2026-07-23
- **Deciders:** Respellion engineering
- **Slice:** S-16a (#122), first of the S-16 (#17) split
-
-## Context
-
-The PRD calls for "OpenTelemetry traces, Prometheus metrics; a local Grafana with
-pre-built dashboards" (§80). S-16 was split (CLAUDE.md §13) into a backplane slice
-(this one), distributed tracing (#123), and metrics + dashboards (#124). The
-backplane must stand up first: a local, CI-friendly place for traces and metrics to
-land, viewable in one UI, reaching green health within the 3-minute compose budget.
-
-Two shape decisions are non-obvious enough to record.
-
-## Decision
-
-**Run a Grafana-native stack — Grafana Tempo (traces) + Prometheus (metrics) +
-Grafana (UI) — with the services exporting OTLP straight to Tempo (no collector),
-and ship the config baked into small built images.**
-
-### Trace backend: Tempo (not Jaeger)
-
-Tempo keeps everything under one Grafana pane alongside metrics (and later logs),
-which is exactly the "local Grafana with dashboards" the PRD asks for. Jaeger would
-add a second UI and a second mental model for no benefit at this scale.
-
-### No OTLP collector
-
-Tempo ingests OTLP directly (gRPC 4317 / HTTP 4318) and Prometheus scrapes each
-service's `/metrics`, so a collector would be a hop that processes nothing. Skipped.
-If we later need fan-out, tail sampling, or log processing, a collector is an
-additive change — the services already speak OTLP.
-
-### Config baked into built images, not config volumes
-
-The upstream Common Ground modules (OpenZaak, NRC, Keycloak, Flowable) run as
-**verbatim** images and get their config streamed into external named volumes by
-`infra/seed-config.sh`, because bind mounts don't reach sibling containers on the
-CI runner (see `docs/runbooks/gitea-actions-gotchas.md`). The observability tools
-are **not** peer modules we must run verbatim, so we take the simpler path: a
-three-line `Dockerfile` per tool that `COPY`s its config in. This reaches sibling
-containers everywhere (docker, podman, CI) with no seed step, no `CFG_VOLS` entry,
-and no Makefile sprawl.
-
-### Verified, not assumed
-
-`infra/run-observability-check.sh` (the `verify-observability` step, run early in CI
-`verify-stack`) asks Grafana to reach both datasources — Prometheus via its health
-method, Tempo via the datasource proxy (Tempo's Grafana plugin implements no health
-method) — so the check proves the datasources are actually wired, not merely that
-containers started. The containers are not in `WAIT_SVCS`; the check polls Grafana
-itself, so no in-image healthcheck tool is required.
-
-## Consequences
-
-**Positive**
-
- One UI for traces + metrics + (future) logs. Config is versioned in
-  `infra/observability/` and self-contained in the images.
- Backplane is independent of app instrumentation — #123 and #124 build on it.
-
-**Negative / costs**
-
- Three more images built each CI run (kept small; not on the health-gate list).
- Storage is ephemeral container fs — a demo backplane, not a retention target.
-  Object storage for Tempo / remote-write for Prometheus is a later concern.
-
-## Coupling rules touched (CLAUDE.md §8)
-
-None. The stack is passive infrastructure: services *push* OTLP and *expose*
-`/metrics`; nothing in the stack calls into a service or a peer module.

-## S-16b — distributed traces across the .NET services (#123, ADR-0023)
-
-**Outcome:** the five .NET services (BFF, Domain, ACL, projection-api, event-subscriber) now emit
-OpenTelemetry traces — ASP.NET Core + `HttpClient` auto-instrumentation, exported over OTLP to Tempo.
-Because every cross-service call goes through a typed `HttpClient`, the W3C `traceparent` propagates for
-free, so a request is **one connected trace** across the services (bff → domain → acl → openzaak;
-bff → projection-api). `/health` is filtered out. No browser-side instrumentation yet, so the trace
-begins at the BFF; the async Flowable-poll boundary is a separate trace (ADR-0023).
-
-```bash
-# 1. Automated (a CI verify-stack step): generate BFF traffic and assert Tempo holds one trace
-#    spanning multiple services.
-make verify-tracing              # → OK — trace <id> spans ['bff', 'projection-api']
-
-# 2. By hand: drive the stack, then explore traces in Grafana.
-make up
-curl -s localhost:8080/openbaar/register >/dev/null   # BFF → projection-api
-open http://localhost:3000       # Grafana → Explore → Tempo → Search → service.name = bff → open a trace

-AddHttpClientInstrumentation + AddOtlpExporter)`; `OTEL_SERVICE_NAME` / `OTEL_EXPORTER_OTLP_ENDPOINT`

-
-**Outcome:** the compose stack now includes a Grafana-native observability backplane — **Tempo** (OTLP
-trace ingest on 4317/4318), **Prometheus**, and **Grafana** with both datasources auto-provisioned.
-Nothing is instrumented yet (traces land in S-16b, metrics + dashboards in S-16c); this slice stands the

-## S-17 — herregistratie reminder sweep on a Quartz cron (#18, ADR-0022)
-
-**Outcome:** an inscription (INGESCHREVEN) now carries the moment it was entered in the register, from
-which its herregistratie deadline is derived (inscription + 5-year validity). A **Quartz.NET** cron job
-in the Domain Service sweeps once a day (03:00, overridable via `Quartz__Cron`): every inscription
-inside the 90-day window before its deadline is flagged `HerregistratieReminderVerstuurd` and logged.
-The sweep is idempotent — a re-fire reminds no one twice — and is a deliberately different mechanism
-from the queue-draining pumps (Quartz fires time-triggered sweeps; pumps drain Flowable queues,
-ADR-0022). There is no outbound notification in v1: the reminder is the flag on the aggregate plus a
-log line.
-
-```bash
-# 1. The domain unit tests prove the rule and the sweep end to end (rule → store query → sweep):
-cd services/domain && dotnet test Big.Tests/Big.Tests.csproj \
-  --filter "FullyQualifiedName~Herregistratie|FullyQualifiedName~ReminderSweep"
-#    → the reminder is due once the 90-day window opens, not before; a reminded inscription is skipped
-#      on the next sweep; the sweep flags + persists every due inscription and returns their ids.
-
-# 2. The read model surfaces the deadline once a registration is approved — the field the sweep acts on:
-curl -s localhost:8000/registrations/<id> | jq '{status, herregistratieVoor, herregistratieReminderVerstuurd}'
-#    → after approval: herregistratieVoor is inscription + 5 years; the flag flips true once swept.
-```
-
-**The path:** `Registration.Approve(now)` stamps `IngeschrevenOp` → daily Quartz `HerregistratieReminderJob`
-→ `HerregistratieReminderSweep` → `IRegistrationStore.FindDueForHerregistratieReminderAsync` (filtered by
-the aggregate's own `HerregistratieReminderDue` rule) → `MarkHerregistratieReminderVerstuurd` + log.

 ## S-B04 — `make local` completes the whole flow with no manual seeding (#110, ADR-0020)

-## S-27 — ACL resolves its zaaktype by identificatie, not a pinned URL (#113, ADR-0021)
-
-**Outcome:** the ACL discovers its BIG zaaktype (by `identificatie`) and diploma informatieobjecttype
-(by `omschrijving`) from OpenZaak's Catalogi API, instead of being handed the server-assigned URLs.
-No user-visible behaviour change — the flow runs exactly as before — but no stack captures/injects a
-zaaktype URL any more, and a missing catalogus now fails with a clear message instead of an opaque 400.
-
-```bash
-# The live ACL↔OpenZaak integration test proves resolution against a real seeded OpenZaak:
-make verify-acl     # → "resolves the published BIG-REGISTRATIE zaaktype + Diploma informatieobjecttype by business key"
-
-# End-to-end unchanged (the ACL self-discovers the zaaktype during the flow):
-make verify-local   # local stack — still green, now with no zaaktype-URL injection
-make verify-domain  # CI stack — recreates the ACL pointed only at OpenZaak's IP (no URL to inject)
-```
-
-> The ACL still needs its OpenZaak base URL at a URL-valid host (a container IP): OpenZaak's
-> URLValidator rejects a single-label host like `openzaak:8000` on zaak-create. So ADR-0020's base-URL
-> injection stays; only the zaaktype/informatieobjecttype **URL** injection is gone (ADR-0021).
+> The zaaktype UUID is server-assigned, so `local-seed` writes the real URL into a shared volume as
+> `acl.env` and the ACL sources it on startup (ADR-0020). The cleaner long-term fix — the ACL
+> resolving its zaaktype by `identificatie` — is tracked separately as S-27 (#113).

Both one-shots reach OpenZaak/NRC by container IP (a single-label host fails their Django URLValidator), mirroring the CI verify scripts. Asserted by `make verify-local`.
