+- **S-08a (#65)** · Nx monorepo + Angular tooling + CI Node lane. Placeholder `self-service` app; `nx lint/test/build` green in a new CI Node lane.
+- **S-08b (#66)** · Generated api-client lib from `services/bff/openapi.json` (never hand-written, §10) + a mocked-BFF unit test.
+- **S-08c (#67)** · Self-service submit form — NL Design System `libs/ui`, DigiD OIDC `libs/auth`, component tests (Angular Testing Library), axe WCAG 2.1 AA on the submit page.

+# ADR-0010: The BFF validates Keycloak tokens and is the portals' only backend
+
+- **Status:** Accepted
+- **Date:** 2026-07-01
+- **Deciders:** Respellion engineering
+- **Relates to:** S-07 (#8); proposal #63; builds on ADR-0001 (loose coupling, §8.3), S-02 (#3, Keycloak realms), S-05 (#6, Domain Service), S-06 (#7, read projection)
+
+## Context
+
+S-07 (#8) adds the **BFF (Backend-for-Frontend)** — the single backend the Angular portals talk
+to (CLAUDE.md §8.3). For the walking skeleton it exposes two endpoints and fans out to services
+already built:
+
+- `POST /self-service/registrations` → Domain Service `POST /registrations` (S-05).
+- `GET /openbaar/register?q=…` → projection-api `GET /register` (S-06).
+
+It must validate tokens issued by Keycloak (S-02). This is an ADR-worthy moment (§14): a new
+dependency (JWT bearer authentication) and two new service boundaries (BFF→domain, BFF→projection).
+
+## Decision
+
+**The BFF is the portals' only backend; it validates Keycloak `digid`-realm JWTs on the
+self-service endpoint, leaves the openbaar lookup anonymous, and fans out to the domain and
+projection over typed HTTP clients.**
+
+- **Auth model.** `POST /self-service/registrations` requires a valid `digid`-realm bearer token;
+  the BFF reads the `bsn` claim and forwards it to the domain. Missing / invalid / expired token →
+  **401**. `GET /openbaar/register` is **anonymous** — the openbaar register is a public lookup
+  (S-09), so no token is required.
+- **Portals talk only to the BFF (§8.3).** They never call the Domain Service, ACL, projection, or
+  OpenZaak directly. The BFF orchestrates via typed `HttpClient`s whose base URLs come from config.
+  Downstream calls are unauthenticated on the internal network for the walking skeleton; a
+  service-to-service auth story (e.g. client-credentials) is a later slice, not this one.
+- **Validation is `Microsoft.AspNetCore.Authentication.JwtBearer`** pointed at the Keycloak `digid`
+  realm authority. **New dependency justification:** it gives us standards-based OIDC/JWT validation
+  (signature, issuer, expiry, audience) maintained by the framework; rolling our own JWT validation
+  would be error-prone security code; the risk is a first-party ASP.NET Core package — minimal.
+- **Tests mint their own tokens.** `WebApplicationFactory` tests override the bearer options with a
+  **test signing key**, so valid / invalid / expired tokens are minted in-process without a live
+  Keycloak. Real Keycloak validation is exercised by a live-stack `verify-bff` check.
+- **OpenAPI is generated and committed** (`services/bff/openapi.json`) from .NET's built-in OpenAPI,
+  so S-08's Angular client is generated from the spec, never hand-written (§10).
+
+## Known wrinkle — container OIDC issuer mismatch
+
+Keycloak stamps tokens with an `iss` equal to its **browser-facing** URL (what the portal used to
+log in), which differs from the BFF's **in-container** authority (`http://keycloak:8080/realms/digid`).
+Strict issuer validation then rejects otherwise-valid tokens. Unit tests avoid this (test key).
+`verify-bff` handles it by aligning the configured authority/issuer with the token's `iss` (and, if
+needed, disabling metadata address rewriting). Recorded so it is not rediscovered each time.
+
+## Consequences
+
+- **Positive:** the walking skeleton gains its front door; §8.3 holds with all portal traffic going
+  through one backend; token validation is standard and testable without infra; the committed
+  OpenAPI unblocks S-08.
+- **Negative / deferred:**
+  - Downstream service-to-service auth is deferred (internal-network trust for now).
+  - The openbaar endpoint is anonymous; when public-safe field filtering tightens (S-09) it stays
+    anonymous but the projection query narrows.
+  - The issuer-mismatch handling is dev-oriented; a production reverse-proxy setup would align the
+    browser and internal issuer URLs instead.
+
+## Alternatives considered
+
+- **Token-gate the openbaar endpoint too** — rejected: the openbaar register is public by design
+  (S-09); requiring a login would contradict the slice's intent.
+- **Validate tokens by calling Keycloak's introspection endpoint per request** — rejected: adds a
+  network hop per call and a Keycloak dependency on the hot path; local JWT signature validation via
+  the realm's JWKS is the standard, faster choice.
+- **Hand-written JWT parsing** — rejected: security-sensitive code we shouldn't own when a
+  first-party validator exists.
+- **Generate the OpenAPI client by hand / keep the spec uncommitted** — rejected: §10 requires a
+  generated client from a committed spec.

+# ADR-0011: Approval sets the zaak eindstatus via the ACL and projects INGESCHREVEN from the notification alone
+
+- **Status:** Accepted
+- **Date:** 2026-07-13
+- **Deciders:** Respellion engineering
+- **Relates to:** S-09b (#75); split from S-09 (#10); builds on ADR-0001 (§8 loose coupling), ADR-0003 (ACL default-fill), ADR-0007 (OZ→NRC wiring), ADR-0008 (read projection), ADR-0009 (external-task worker)
+
+## Context
+
+The walking skeleton could submit a registration (INGEDIEND) and show it in the openbaar register,
+but nothing could **approve** it. S-09b adds a behandelaar approval that must make the entry publicly
+visible as a terminal status. There is no behandel-portal yet (S-12), so approval is triggered by a
+**temporary admin endpoint** on the Domain Service.
+
+Two decisions are non-obvious (§14) and cross service boundaries:
+
+1. **Who resolves the ZGW statustype?** Approval means "set the zaak to its final status", but the
+   domain must stay ZGW-ignorant (§8.1 — only the ACL talks to ZGW) and does not know statustype URLs.
+2. **How does the projection learn the new status?** The status is set in OpenZaak, which notifies over
+   NRC; the Event Subscriber projects it. But the subscriber **may not read OpenZaak** (§8.1), and an
+   NRC `status`/`create` notification's `resourceUrl` is the *status* resource, not the zaak, and does
+   not carry the statustype.
+
+## Decision
+
+**Approval flows Domain → ACL → OpenZaak → NRC → Event Subscriber → projection, using only the
+notification's own fields on the read side.**
+
+- **Domain.** `Registration.Approve()` advances INGEDIEND → INGESCHREVEN (requires an opened zaak; a
+  repeat is a no-op). The `ApproveRegistration` use case calls the ACL to set the zaak status, then
+  advances the aggregate. A temporary `POST /registrations/{id}/approve` endpoint drives it.
+- **ACL.** A new `POST /statussen` operation takes only the zaak URL. The ACL resolves the zaaktype's
+  **eindstatus** from the catalogus (`isEindstatus`, falling back to the highest `volgnummer`) and
+  POSTs a ZGW status against the zaak. The domain never names statustypen — the ACL owns the ZGW
+  translation (§8.1, ADR-0003).
+- **Event Subscriber.** It binds the NRC `hoofdObject` (always the zaak URL) and keys the projection on
+  it, so a `zaken`/`status`/`create` notification updates the **same** row the zaak-create created,
+  flipping it to INGESCHREVEN. It takes **any** status-create as the approval — in the walking skeleton
+  the only status ever set after creation is the approval — so it never has to read OpenZaak to learn
+  the statustype. The ZGW `resource` is retained in the notification log (new column) so a rebuild
+  reproduces the right status.
+
+## Consequences
+
+- The domain↔ACL boundary stays clean: the domain hands over a zaak URL and says "approve"; ZGW
+  statustype knowledge lives only in the ACL.
+- The projection remains rebuildable without OpenZaak (§8.1, ADR-0008): the log now records the ZGW
+  resource, which is all a rebuild needs to reproject the status.
+- The openbaar register shows real lifecycle: INGEDIEND on submit, INGESCHREVEN on approval.
+- **Walking-skeleton assumption:** "any status-create ⇒ INGESCHREVEN" holds only while approval is the
+  sole post-creation status transition. When more transitions arrive (beoordeling, afwijzing — S-12+),
+  the subscriber must distinguish statustypen. The honest options then are to carry the statustype
+  omschrijving in the notification `kenmerken`, or to have the ACL resolve it and re-notify — recorded
+  here so future-me revisits this rather than assuming it generalises.
+
+## Alternatives considered
+
+- **Inject the approved statustype URL into the ACL as config** (like the zaaktype URL). Rejected:
+  couples ACL config to seed output and adds compose/run-domain-check plumbing; runtime eindstatus
+  discovery keeps the ACL self-contained for one extra ZGW GET per approval.
+- **Have the Event Subscriber GET the status/statustype from OpenZaak** to map precisely. Rejected:
+  violates §8.1 (only the ACL talks to ZGW) and makes the projection depend on OpenZaak being up.
+- **Record the derived status in the notification log** instead of the ZGW resource. Rejected: the log
+  should retain notification *facts*, not projection semantics; the mapping stays in the projector.

+# ADR-0012: One citizen-facing reference across self-service and the openbaar register
+
+- **Status:** Accepted
+- **Date:** 2026-07-14
+- **Deciders:** Respellion engineering
+- **Relates to:** #78 (adr-proposal); builds on ADR-0008 (read projection), ADR-0001 (loose coupling), ADR-0009 (external-task worker / zaak creation)
+
+## Context
+
+A citizen submits through the self-service portal and is shown a confirmation with a
+**reference** so they can find their registration back in the public register. But the two
+sides showed **different identifiers**:
+
+- The self-service confirmation shows the **domain `registrationId`** — a GUID minted by the
+  domain aggregate (`RegistrationId.New()`) when the registration is created, before any zaak
+  exists.
+- The openbaar register showed the **zaak id** — the UUID from the NRC `hoofdObject` URL,
+  assigned by OpenZaak when the ACL opens the zaak.
+
+These never match, so the reference on the confirmation was useless for looking the entry up.
+The two identifiers live on opposite sides of the ACL boundary and are generated by different
+systems at different times, so there is no way to reconcile them after the fact without a
+correlating value carried across the boundary.
+
+The NRC notification the Event Subscriber consumes carries only the zaak URL plus the fixed
+`kenmerken` (`bronorganisatie`, `zaaktype`, `vertrouwelijkheidaanduiding`) — **not** the
+`registrationId`, the bsn, or the `identificatie`. ADR-0008 already recorded that filling any
+such field means reading the zaak **through the ACL** (§8.1) and deferred it as a follow-up.
+This is that follow-up, scoped to the one field the citizen actually needs.
+
+## Decision
+
+**Use the domain `registrationId` as the zaak's `identificatie`, and surface that single value
+as the citizen-facing `reference` on both portals. The Event Subscriber enriches the projection
+with the reference by reading the zaak through the ACL, and stores it in the replay log so
+rebuild stays log-only.**
+
+Concretely, following the request path:
+
+1. **Domain → ACL (write).** When the OpenZaak worker opens a zaak, it passes
+   `registration.Id` to the ACL (`IAclClient.OpenZaakAsync(bsn, reference, …)`). The ACL sets
+   it as the zaak's `identificatie` on `POST /zaken`. OpenZaak's `identificatie` is unique per
+   `bronorganisatie` and ≤ 40 chars — a GUID string fits. The ACL remains the only code that
+   constructs ZGW payloads (§8.1); the domain never sees a ZGW URL.
+2. **Event Subscriber → ACL (read).** On a notification, the subscriber asks the ACL for the
+   zaak's reference via a new `POST /zaken/reference` endpoint (`{ zaakUrl } → { reference }`),
+   which reads the zaak's `identificatie` through the ACL's OpenZaak gateway. The subscriber
+   still never talks to ZGW itself (§8.1) — it depends only on the ACL, over HTTP.
+3. **Projection + replay log.** The reference is written both to the `register_projection` row
+   **and** to the `processed_notifications` replay log (a new nullable `reference` column on
+   each). Storing it in the log is what keeps ADR-0008's "**rebuild replays the log, not
+   OpenZaak**" invariant true: `POST /admin/rebuild` reproduces the reference from the log
+   without re-reading the ACL.
+4. **BFF + openbaar.** The public view (`OpenbaarProjection.PublicView`) exposes
+   `id`, `status`, and `reference` (never bsn/naam), and the openbaar search matches on either
+   `id` or `reference`. The openbaar register's "Referentie" column now renders `reference`.
+
+The end-to-end guarantee is asserted in the Playwright walking-skeleton: the reference captured
+from the submit confirmation must appear as a cell in the public register.
+
+### Why HTTP to the ACL, not the ACL as a library
+
+ADR-0008 floated "extend the ACL with a zaak-read operation, consumed as a library." We instead
+call the ACL **over HTTP**, consistent with every other cross-service hop in this system
+(portals→BFF, domain→ACL). Sharing the ACL as a library would couple the subscriber to the
+ACL's infrastructure assembly and its ZGW client configuration, defeating the anti-corruption
+boundary. The HTTP endpoint keeps the ACL the single owner of ZGW access and its config.
+
+## Consequences
+
+**Positive**
+
+- One reference, end to end: the citizen's confirmation value is exactly what the public
+  register shows and searches by.
+- §8.1 stays intact — only the ACL reads or writes ZGW; the subscriber depends on the ACL, not
+  OpenZaak.
+- Rebuild stays log-only (ADR-0008): the reference is replayed from `processed_notifications`,
+  so `/admin/rebuild` needs no ACL/ZGW access.
+- The column additions are nullable and additive; older rows without a reference are tolerated.
+
+**Negative / costs**
+
+- A new coupling: the Event Subscriber now depends on the ACL being reachable
+  (`Acl__BaseUrl`, compose `depends_on: acl`). A registration whose reference read fails will
+  need the notification redelivered (NRC already redelivers; the projection upsert is
+  idempotent).
+- One extra HTTP hop per notification (subscriber→ACL→OpenZaak) on the projection path. Bounded:
+  one small GET per zaak, off the citizen's request path.
+- `identificatie` now carries semantic meaning (it equals the `registrationId`). If OpenZaak
+  were ever configured to auto-generate `identificatie`, the correlation would break; the ACL
+  setting it explicitly is now load-bearing.
+
+## Alternatives considered
+
+- **Carry the `registrationId` in the notification** — rejected: NRC `kenmerken` are fixed and
+  the notification content is not ours to extend; it would also couple the projection to a
+  bespoke notification shape.
+- **Show the zaak id on the confirmation instead** — rejected: the zaak does not exist yet when
+  the confirmation is returned (the worker opens it asynchronously, ADR-0009), so the domain has
+  no zaak id to show at submit time.
+- **Store only on the projection row, re-read the ACL on rebuild** — rejected: it would make
+  rebuild depend on the ACL/ZGW, breaking ADR-0008's log-only rebuild invariant.
+- **Reconcile the two ids in a lookup table** — rejected: adds write-only state and a second
+  source of truth for a value that can simply be the same on both sides.

+runs in a real browser — **mock DigiD login → submit → confirmation** — closing the walking skeleton
+(portal → BFF → domain → Flowable → ACL → OpenZaak, with the openbaar register reading the projection).

+
+# 2. Automated happy path — Playwright, inside the compose network (issuer-consistent):

+

+## S-08c — Self-service submit form (NL Design System + DigiD)
+
+**Outcome:** a zorgprofessional logs in via mock DigiD and submits a BIG registration through the
+self-service portal (NL Design System styling); the page confirms with the reference returned by the
+BFF. The bsn comes from the DigiD token, so it's a confirm-and-submit flow (no bsn field).

+
+## S-07 — BFF: the portals' single backend
+
+**Outcome:** the BFF validates Keycloak `digid` tokens on the self-service submit (forwarding the
+bsn to the domain) and serves the openbaar register anonymously with only public-safe fields — the
+front door the portals (S-08/S-09) will talk to.
+
+**The path:** portal → BFF `POST /self-service/registrations` (token-gated) → domain; and
+BFF `GET /openbaar/register` (anonymous) → projection-api. See ADR-0010.
+
+```bash
+# 1. Bring the full stack up.
+make up
+
+# 2. Drive the BFF end-to-end (401 without a token, 202 with a real digid token, anonymous openbaar).
+make verify-bff        # → "OK — BFF: 401 without token, 202 with a digid token, anonymous ..."
+
+# 3. Try it by hand (BFF on host port 8080).
+#    a) A digid access token for the mock user jan-burger (bsn 123456782):

+
+#    b) Submit — without the token it is 401; with it, 202:
+curl -s -o /dev/null -w "no token  -> %{http_code}\n" -X POST http://localhost:8080/self-service/registrations
+curl -s -o /dev/null -w "with token-> %{http_code}\n" -X POST http://localhost:8080/self-service/registrations \

+**Outcome:** the entry a zorgprofessional submits via self-service becomes publicly visible in the

+# Frontend decisions
+
+A running log of frontend tooling and component decisions (CLAUDE.md §10). One entry per
+decision; record *why*, and note any deviation from NL Design System.
+
+---
+
+## Workspace & tooling (S-08a, #65)
+
+The portals live in an **Nx monorepo at the repository root**, alongside the .NET `services/`.
+
+- **Package manager: pnpm.** Native build scripts are approved explicitly in `pnpm-workspace.yaml`
+  under `allowBuilds` (pnpm 11 fails the install otherwise). Node 24, pnpm 11.
+- **Angular, standalone components + signals, no NgModules** (§10). Apps are generated with
+  `@nx/angular:application`.
+- **Unit tests: Vitest** via Angular's built-in `@angular/build:unit-test` (the `vitest-angular`
+  runner). **Angular Testing Library** is added for component tests when the first real components
+  land (S-08c); the S-08a placeholder uses a plain `TestBed` render assertion.
+- **Lint: ESLint** (flat config, `@nx/eslint`).
+- **Nx is scoped to `apps/` + `libs/` only.** The `@nx/docker` and `@nx/dotnet` plugins are **not**
+  installed — the .NET services are built by `dotnet`/the Makefile, and `@nx/docker` would otherwise
+  infer every `services/*/Dockerfile` as an unnamed Nx project and break the project graph.
+- **No Nx Cloud.** `nxCloudId` is stripped from `nx.json`; remote caching would depend on an
+  external service, and the repo is Gitea-only (§8.7). Nx's "configure-ai-agents" additions
+  (`.claude/settings.json`, a CLAUDE.md section referencing a GitHub marketplace) are **not**
+  committed for the same reason.
+- **CI:** a `frontend` job (`make frontend` → `pnpm install --frozen-lockfile` + `nx run-many -t
+  lint test build`) runs on pnpm + Node, with pinned action URLs (§15).
+
+**NL Design System:** not yet introduced — the S-08a app is a placeholder. NL DS components arrive
+with the submit form (S-08c, #67); any deviation from NL DS will be recorded here.
+
+---
+
+## API client generator (S-08b, #66)
+
+`libs/api-client` is **generated from `services/bff/openapi.json`** — never hand-written (§10).
+
+- **Generator: orval** (`client: 'angular'`), a **node-based** generator (no Java, unlike
+  `openapi-generator`), so it runs in the pnpm/Node CI lane. It emits an injectable
+  `BffApiV1Service` using Angular's `HttpClient` — which means the DigiD bearer token can be attached
+  by an **`HttpInterceptor`** (S-08c), the idiomatic Angular approach; a fetch-based SDK would bypass
+  the interceptor pipeline.
+- **Config:** `libs/api-client/orval.config.ts` (single-file output into `src/lib/generated/`,
+  `clean: true`, prettier). **Regenerate with `nx run api-client:generate`** after the BFF spec
+  changes; the output is deterministic (idempotent), and `src/lib/generated/` is never hand-edited.
+- **Tested** against a mocked BFF via `HttpClientTesting` (`libs/api-client/src/lib/bff-api.spec.ts`).
+- The BFF endpoints carry no `operationId`, so orval synthesises method names
+  (`postSelfServiceRegistrations`, `getOpenbaarRegister`); adding explicit operation ids to the BFF
+  is a possible later polish.
+
+---
+
+## Self-service form: NL DS, DigiD auth, testing (S-08c, #67)
+
+- **NL Design System via `@utrecht/component-library-angular`** (`libs/ui`) + `@utrecht/design-tokens`
+  (imported once in `apps/self-service/src/styles.css`). Utrecht is NL DS's reference Angular
+  implementation. Its v3 components are **NgModule-based, not standalone**, so `libs/ui` re-exports
+  `UtrechtComponentsModule` (and the component classes, so the AOT compiler resolves the template
+  directives through the barrel); standalone components consume it via `imports: [UtrechtComponentsModule]`.
+  §10's "no NgModules in new code" governs *our* code — consuming a third-party module is fine.
+- **DigiD login via `angular-auth-oidc-client`** (`libs/auth`): auth-code + PKCE against the Keycloak
+  `digid` realm (public client `big-portal`). A small **`AuthService` abstraction** (bsn /
+  isAuthenticated / login) wraps the library so components and the `authenticatedGuard` depend on a
+  mockable surface; a **token `HttpInterceptor`** attaches the bearer to BFF calls (secure route).
+  The OIDC `authority`/`secureApiOrigin` are dev defaults in `app.config.ts`; the compose-served app
+  overrides them (S-08d), and the browser-vs-container issuer alignment is handled there (ADR-0010).
+- **Testing:** component tests use **`@testing-library/angular`** (§10) with `AuthService` and the
+  api-client mocked; the **axe** (`vitest-axe`) check runs scoped to WCAG 2.1 AA tags
+  (`wcag2a/2aa/21a/21aa`) with the document `lang` set, asserting zero violations on the submit page.
+  The real DigiD browser round-trip is exercised in S-08d (Playwright).
+- **Module boundaries:** replaced the demo eslint `depConstraints` (`scope:shop`/`scope:shared`, left
+  over from the Nx angular template) with a permissive `*` default; scope/type tags can be
+  introduced when the portal set grows.
+
+---
+
+## Serving + e2e (S-08d, #68)
+
+- **Served by nginx, same-origin as the BFF.** The compose `self-service` image serves the built app
+  and **reverse-proxies** `/self-service/*` + `/openbaar/*` to the `bff` service. Because the
+  api-client uses **relative URLs**, the browser calls the app's own origin → nginx forwards to the
+  BFF: **no CORS**, and the DigiD token (same-origin) is attached by the interceptor. nginx resolves
+  the BFF at request time (a `resolver` + variable `proxy_pass`) so it starts before the BFF is up.
+- **Runtime config.** The app fetches `/config.json` before bootstrap (`main.ts`); `appConfig` is a
+  factory. The dev default (`public/config.json`) points at `localhost:8180`; the Docker image bakes
+  the compose value (`keycloak:8080`). One build, per-environment OIDC authority.
+- **e2e runs inside the compose network.** `infra/run-e2e-check.sh` runs Playwright in a container on
+  `cg`, so the browser reaches Keycloak as `keycloak:8080` — the **same issuer** the BFF validates
+  against (resolves the browser-vs-container mismatch, ADR-0010). It uses the official
+  `mcr.microsoft.com/playwright:<version>` image with browsers pre-baked, rather than downloading
+  ~150 MB of Chromium on every run (issue #73) — the image tag is kept in lockstep with
+  `tests/e2e/package.json`'s `@playwright/test` version. The spec is copied in (`docker cp`), not
+  mounted, so it leaves nothing root-owned on the host. Wired as `verify-e2e` in the `verify-stack`
+  CI job.
+- **e2e treats the portal origin as secure.** In-network the portal is served over plain HTTP on a
+  non-localhost origin (`http://self-service`), which is **not a secure context**, so Web Crypto
+  (`crypto.subtle`) is unavailable. angular-auth-oidc-client needs it for the PKCE code challenge, so
+  `authorize()` throws and the login redirect never fires. Production runs behind HTTPS where this is
+  a non-issue; rather than terminate TLS in the throwaway stack, the Playwright config passes
+  `--unsafely-treat-insecure-origin-as-secure` (honoured only by the full `channel: 'chromium'`
+  build, not the default headless-shell). This emulates the production HTTPS secure context without
+  touching the app or its production config.
+- `tests/e2e` is a standalone Playwright project (its own `package.json`), not an Nx project — it's a
+  live-stack check like the other `verify-*` runners, not part of the `frontend` unit lane.
+
+## Openbaar Register portal (S-09, #10)
+
+- **Anonymous, no auth.** The openbaar register is a public read, so `apps/openbaar` has no
+  `angular-auth-oidc-client`, no interceptor, and no `config.json` — `main.ts` bootstraps `appConfig`
+  directly with just `provideHttpClient` + `provideRouter`. This is the deliberate contrast to
+  self-service and keeps the app trivially cacheable/CDN-able.
+- **Same-origin via nginx, like self-service.** The compose `openbaar` image serves the built app and

+- **Loads on open, filters on search.** `RegisterPage` fetches the full register on construction and
+  re-queries `/openbaar/register?q=` on search — no client-side filtering, the BFF owns the query.
