## What & why
Third sub-slice of **S-11 · Withdrawal (Flow 3)** (#12) — the **owner-scoped BFF withdraw endpoint** (backend). S-11a/b made a withdrawal transition the aggregate and cancel the workflow; this adds the citizen-facing entry point through the BFF, gated to the registration's owner.
- **Domain**: `WithdrawRegistrationCommand` carries the caller's `bsn`; the handler returns a `WithdrawOutcome` and refuses a bsn that doesn't own the registration. Unknown and not-owned are **both 404** (indistinguishable — ownership isn't revealed). `POST /registrations/{id}/withdraw` takes `{bsn}` and maps the outcome (204/404).
- **BFF**: `POST /self-service/registrations/{id}/withdraw` (DigiD-authenticated) forwards the token's `bsn` to the domain and relays 204/404. The BFF authenticates; the domain owner-scopes (an aggregate invariant, not the domain doing auth).
- OpenAPI spec + Angular client regenerated for the new endpoint.
- `run-domain-check.sh` withdrawal step now sends the owner `bsn` (verify-stack).
Refs #12 — the self-service "trek aanvraag in" button + e2e (S-11c-2) closes it.
## Definition of Done
- [x] Linked Gitea issue (#12).
- [x] Failing tests committed before the implementation.
- [x] Implementation makes the tests pass.
- [x] Conventional Commits referencing the issue (`refs #12`).
- [ ] CI green — all Gitea Actions jobs.
- [x] `docker compose up` unaffected.
- [x] No ADR needed (owner-scoping is an aggregate invariant; no boundary change).
- [x] Docs — the user-visible demo note lands with S-11c-2.
## Notes for reviewers
- **Full local gate run before pushing this time** (lessons from #89): `dotnet format --verify-no-changes` clean; `make unit` green — Acl 27, EventSubscriber 19, BFF 30, Acceptance 9, Big 95; `api-client` lint+test green.
- Owner mismatch returns 404 (not 403) so the portal can't be used to probe which references exist.

## What & why
Second sub-slice of **S-11 · Withdrawal (Flow 3)** (#12). S-11a (#88) made a withdrawal advance the aggregate to INGETROKKEN; this sub-slice **cancels the running Flowable process** so the withdrawn case leaves the behandelaar's werkbak.
- **BPMN** (`registratie.bpmn`): an interrupting message boundary event (`RegistratieIngetrokken`) on the `Beoordelen` task, routing to a dedicated "Registratie ingetrokken" end event.
- **Workflow Client**: `WithdrawBeoordelingAsync(executionId)` delivers `messageEventReceived` to the task's execution (PUT); `BeoordelingTask` now carries its `executionId`.
- **`WithdrawRegistration` handler**: after the domain transition, finds the open `Beoordelen` task for the registration and delivers the withdrawal message — best-effort, mirroring how the beoordeling completes its task.
- **Werkbak**: also filters out registrations that are no longer open, so a withdrawn case never surfaces even in the brief window before cancellation lands.
- **ADR-0014** records the decision (message event in BPMN vs. deleting the instance from code).
- **verify (`run-domain-check.sh`)**: a second registration parks at `Beoordelen`, is withdrawn via the domain, and the check asserts its `Beoordelen` task disappears — so verify-stack validates the live Flowable message correlation.
Refs #12 (S-11c — the BFF + self-service "trek aanvraag in" button + e2e — closes it).

## Notes for reviewers
- Verified locally: `Big.Tests` 94/94 pass; `Big.Api` builds; `registratie.bpmn` is well-formed.
- The Flowable message-correlation REST shape is validated **live** by verify-stack (the Workflow Client unit tests stub the exchange and assert only the request shape, per ADR-0009) — the new `run-domain-check.sh` withdrawal step is that live check.
- Known gap (ADR-0014): a withdrawal that races ahead of the process reaching `Beoordelen` finds no task to cancel; the aggregate is still INGETROKKEN and the werkbak filter hides it, but that instance parks unattended. A process-level event subprocess would close the gap — deferred.

## What & why
Second half of **S-12c** (behandel-portal backend), completing the decision path per **ADR-0013**:
- **Domain:** `BeoordeelRegistratie` now, after applying the decision (aggregate + ACL for approval), **completes the open Flowable `Beoordelen` task** for that registration (found by registrationId) with the besluit, so the workflow advances. No open task → the decision still stands (completes nothing); idempotent.
- **BFF:** `POST /behandel/registrations/{id}/decide` behind the medewerker/`behandelaar` policy, forwarding `goedkeuren`/`afwijzen` to the domain. Validates the besluit vocabulary (400 on unknown) without troubling the domain.
Behavior: decide is **401** without a token, **403** without the role, **400** for an unknown besluit, **204** (forwarded) for a behandelaar.
This completes the behandel backend. **S-12d** (the Angular behandel-portal + Playwright e2e) closes umbrella #13 and retires the temporary `/approve`.

## What & why
First half of **S-12c** (behandel-portal backend), per **ADR-0013** (decisions recorded in #84):
- **BFF multi-realm auth.** A second JWT bearer scheme (`medewerker`) alongside the default `digid` scheme. On validation it lifts Keycloak's `realm_access.roles` onto the principal, and a `behandelaar` policy (medewerker scheme + `behandelaar` role) gates `/behandel/*`. Self-service keeps the digid scheme.
- **Werkbak = Flowable tasks.** The domain `Werkbak` query reads the open `Beoordelen` tasks (§8.2, S-12b's `IUserTaskClient`) and enriches each with its aggregate's bsn + status; `GET /behandel/werkbak` (domain) is proxied by the BFF `GET /behandel/werkbak` behind the behandelaar policy. The read projection stays the anonymous openbaar model (no premature `IN_BEHANDELING`/personal-data plumbing — deferred in ADR-0008).
Behavior: `/behandel/werkbak` is **401** without a token, **403** for a medewerker lacking the role, **200 + werkbak** for a behandelaar.
**S-12c-2** (next): `POST /behandel/registrations/{id}/decide` → domain decision + complete the Flowable task.

## What & why
Before this change the self-service confirmation and the openbaar register showed **different** identifiers, so a citizen could not look their registration back up (#78). Now both surface the same **reference**:
- **domain → ACL (write):** the domain `registrationId` is set as the zaak's `identificatie` on `POST /zaken`.
- **event-subscriber → ACL (read):** the subscriber reads the zaak's `identificatie` back through the ACL (§8.1 — only the ACL talks to ZGW) via a new `POST /zaken/reference`, and stores it on the projection row **and** the `processed_notifications` replay log.
- **BFF + openbaar:** the public view exposes `id/status/reference` (never bsn/naam) and searches by id or reference; the register's "Referentie" column shows the reference.
Storing the reference in the replay log keeps ADR-0008's **rebuild-is-log-only** invariant intact — `/admin/rebuild` reproduces the reference without re-reading the ACL.
Decision recorded in **ADR-0012**.

## What & why
S-09b (#75, split from #10) — the **approval flow** that completes the walking skeleton. A behandelaar can now approve a submitted registration; the entry flips from `INGEDIEND` to `INGESCHREVEN` in the public register. Flow: `POST /registrations/{id}/approve` (domain) → ACL sets the zaak eindstatus (ZGW `/statussen`) → OpenZaak → NRC → event-subscriber → projection → openbaar.
## Changes (bottom-up, each red→green TDD)
- **Domain** — `RegistrationStatus.Ingeschreven` + `Registration.Approve()` (guards: opened zaak, only from INGEDIEND); `ApproveRegistration` use case (idempotent) + temp `POST /registrations/{id}/approve` endpoint; `IAclClient.ApproveZaakAsync`.
- **ACL** — resolves the zaaktype's **eindstatus** from the catalogus (`isEindstatus` / highest volgnummer) and POSTs a ZGW status; exposed as `POST /statussen`. Unit + real-OpenZaak integration test.
- **Event-subscriber** — binds NRC `hoofdObject`, projects a `status`/`create` as `INGESCHREVEN` keyed on the zaak (updates the existing row), **without reading OpenZaak** (§8.1). Retains the ZGW `resource` in the log (new column + EF migration) so a rebuild reproduces the status.
- **e2e** — extended: submit → public INGEDIEND → approve → public INGESCHREVEN.
- **Docs** — ADR-0011 (the two non-obvious decisions + the walking-skeleton assumption) + demo note.
## Key decisions (see ADR-0011)
- **ACL discovers the eindstatus** (chosen over injecting a statustype URL): no new config/seed plumbing, domain stays ZGW-ignorant.
- **Any post-creation status-set ⇒ INGESCHREVEN**: in the walking skeleton the only status ever set after creation is the approval, and the subscriber may not read ZGW — documented to tighten when more transitions arrive (S-12+).
## Verification
- All .NET unit suites green locally (domain 47, acl 11, event-subscriber 14, bff 16, acceptance 7); Release build + `dotnet format` clean.
- No new compose config (the eindstatus-discovery approach avoided it).
- The real-OpenZaak integration test (ACL status-set) and the full submit→approve→visible e2e run in CI `verify-stack` (live NRC→projection + selectielijst egress, not reproducible locally).

Use-case-level BDD (Reqnroll) driving the real BFF over HTTP with fake downstreams
and locally-minted tokens: a valid DigiD token is accepted and the bsn forwarded
to the domain; a tokenless submit is 401; the openbaar register is anonymous and
never exposes the bsn (ADR-0010). Real Keycloak validation is the verify-bff check.

Use-case-level BDD (Reqnroll) for S-05: a zorgprofessional submits a registration;
the Domain Service starts the registratie process and the OpenZaakAanmaken external
task opens a zaak via the ACL, recorded on the aggregate (ADR-0009). Driven against
in-memory Workflow Client and ACL stand-ins; real Flowable+ACL+OpenZaak delivery is
the live-stack verify-domain check.

Failing unit + acceptance tests for the Event Subscriber's NotificationProjector:
a zaken/zaak/create notification yields one INGEDIEND projection row, duplicate
deliveries collapse to one row, non-zaak/non-create notifications are ignored, and
a rebuild repopulates the projection from the durable notification log (PRD §8.4).
The projector is a no-op stub so the tests compile and fail on the assertions; the
implementation follows in the green commit. The notification log doubles as the
idempotency guard and rebuild source so a rebuild needs no OpenZaak access (§8.1).
