 ### S-08 · Self-Service portal (Angular, NL DS) — submit a registration
 
-**Outcome:** The self-service Angular app, in the Nx monorepo, lets a zorgprofessional log in via mock DigiD and submit a registration. NL Design System styling. Generated API client.
+> **S-08 was split** (CLAUDE.md §13; issue #9 closed) into the sub-slices below — it bundled the
+> Nx bootstrap, the generated client, the NL DS + DigiD form, and a full-stack Playwright e2e, well
+> past 1–2 days. Each sub-slice is independently demoable and CI-green.
+
+- **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.
+- **S-08d (#68)** · Playwright happy-path e2e (login → submit → success) against the full stack + compose serving + CI e2e lane.
+
+**Out of scope (whole of S-08):** document upload, status tracking page.
+
+### S-09 · Openbaar Register portal — public lookup *(#10)*
+
+**Outcome:** The openbaar Angular app shows a search box. Anonymous. Queries the BFF's `/openbaar/register` which reads only the projection's **public-safe** fields. Shows the public-visibility half of the walking skeleton.
+
+_Split from the original S-09 — scoped to the portal only; the approval flow is **S-09b (#75)**._
 
 **Acceptance:**
 
-- E2E test (Playwright): full happy path, login → submit → success page.
+- E2E test: after a zorgprofessional registers via self-service (S-08), the openbaar register shows the entry (as `INGEDIEND`).
-- Component tests (Testing Library) for the form.
+- Public-safe field whitelist enforced and tested (already in the BFF; add a portal component test + a11y check).
-- Accessibility audit (axe-core) passes WCAG 2.1 AA on the submit page.
 
-**Touches:** `apps/self-service/`, `libs/ui/`, `libs/auth/`, `libs/api-client/`, tests.
+**Touches:** `apps/openbaar/`, compose serving, e2e, docs.
 
-**Out of scope:** document upload, status tracking page.

-### S-09 · Openbaar Register portal — public lookup

-**Outcome:** The openbaar Angular app shows a search box. Anonymous. Queries the BFF's `/openbaar/register` which reads only the projection's **public-safe** fields. Confirms the walking skeleton end-to-end.
+**Outcome:** A behandelaar approves a submitted registration via a temporary admin endpoint (no behandel-portal yet — S-12). The approval transitions the zaak status through the ACL → NRC → event-subscriber → projection, and the openbaar register then shows the entry as approved.
 
 **Acceptance:**
 
-- E2E test: zorgprofessional registers via self-service (S-08), behandelaar approves via a temporary admin endpoint (no behandel-portal yet), openbaar register shows the entry.
+- A new terminal/approved status (e.g. `INGESCHREVEN`) exists and is projected.
-- Public-safe field whitelist enforced and tested.
+- Temporary admin approve endpoint transitions a registration via a real ZGW status set (behind the ACL, §8).
+- E2E: register (S-08) → approve → openbaar shows the entry as approved.

+# 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
+  reverse-proxies `/openbaar` to the BFF; the api-client's relative calls stay same-origin (no CORS).
+  Served on `:8141`, health-checked over IPv4 (`127.0.0.1`), no Keycloak dependency.
+- **Public-safe by construction.** The portal only ever sees the BFF's `OpenbaarProjection.PublicView`
+  (id + status); `bsn`/`naam` never leave the BFF. The e2e asserts the bsn never renders.
+- **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.
