## What & why
Final sub-slice of **S-11 · Withdrawal (Flow 3)** — the user-facing "trek aanvraag in" action, which **closes #12**.
- **self-service portal**: the submit confirmation gains a **"Trek aanvraag in"** button. It withdraws the just-submitted registration via `postSelfServiceRegistrationsIdWithdraw(reference)`; success shows an *ingetrokken* confirmation, a failure is surfaced (`role="alert"`) and the action stays available — same confirm-and-surface pattern as submit.
- **acceptance**: `Een registratie intrekken` — owner withdraws → INGETROKKEN + workflow cancelled; a different bsn is reported not-found.
- **e2e**: `withdrawal.spec.ts` — DigiD submit → trek aanvraag in → the portal confirms ingetrokken.
- **docs**: demo-script + frontend-decisions.
Together with S-11a (#88), S-11b (#89), S-11c-1 (#90), this completes the flow: citizen withdraws → domain INGETROKKEN → BPMN message event cancels the process → the case leaves the behandelaar's werkbak.
Closes#12
## 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] Docs updated (demo-script + frontend-decisions).
- [x] ADR — ADR-0014 (from S-11b) covers the cancellation decision; nothing new here.
## Notes for reviewers
- Full local gate run before pushing: `dotnet format --verify-no-changes` clean; `make unit` green (Acceptance **11** incl. the 2 new withdrawal scenarios, Big 95, BFF 30, Acl 27, EventSubscriber 19); self-service lint/test/build green (9 tests, incl. the 2 new withdraw tests).
- `withdrawal.spec.ts` waits on the *ingetrokken* confirmation (which only renders after the withdraw POST returns), so it can't cancel the request early (the 499 lesson from #87). Live-validated by verify-stack.

## What & why
Finishes **S-12 · Behandel-portal — werkbak + beoordeling**. The backend sub-slices (S-12a/b/c-1/c-2) were merged, but the slice's stated outcome — a behandel *portal* with medewerker login, a werkbak, and decide — had no frontend. This adds it.
- **`libs/auth`**: `MedewerkerAuthService` + `provideMedewerkerAuth` (Keycloak `medewerker` realm), a `roles`/`hasRole` surface on the shared `AuthService`, and a realm-roles protocol mapper so the SPA can read `behandelaar`/`teamlead` from the token. The BFF remains the security boundary (ADR-0013).
- **`apps/behandel`**: a new Nx Angular app mirroring self-service — medewerker OIDC login and a **werkbak** page listing registrations awaiting beoordeling (`GET /behandel/werkbak`) with per-row **Goedkeuren/Afwijzen** actions (`POST /behandel/registrations/{id}/decide`) that refresh the list. NL DS/Utrecht, standalone + signals.
- **e2e**: the walking-skeleton happy path now approves through the real portal (behandelaar logs in, finds the row by reference, clicks Goedkeuren) instead of the temporary admin endpoint.
- **infra/docs**: behandel service in compose (`:8142`, depends on Keycloak); added to the smoke `WAIT_SVCS` + CI log dump; `frontend-decisions.md` and `demo-script.md` updated.
Closes#13
## Definition of Done
- [x] Linked Gitea issue (above).
- [x] Failing test committed before the implementation.
- [x] Implementation makes the test pass; refactor commit if structure improved.
- [x] Conventional Commits referencing the issue (`refs #13`).
- [ ] CI green — all Gitea Actions jobs.
- [x] `docker compose up` from a fresh clone reaches green health checks within 3 minutes. *(behandel image + container verified locally; full stack gated in CI.)*
- [x] Docs updated if behaviour, contracts, or operations changed.
- [x] ADR added — ADR-0013 (merged with the backend sub-slices) already covers the wiring; no new decision here.
- [x] Demo note in `docs/demo-script.md`.
## Notes for reviewers
- Verified locally: auth + behandel + all frontend projects pass lint & unit tests (incl. axe WCAG 2.1 AA); production build green; the behandel Docker image builds and serves with the correct baked `medewerker` config + SPA fallback.
- The full compose-up smoke, e2e, and mutation are CI-gated (known local full-stack verify limits).
- **Follow-ups (not in scope):** the `WerkbakItem` contract has no citizen name (werkbak shows the BSN) — adding one is a BFF+domain contract change; and the domain's temporary admin `approve` endpoint is now unused by the e2e and could be removed.

The verify-e2e lane downloaded ~150 MB of Chromium (npx playwright install) on
every verify-stack run. Use the official mcr.microsoft.com/playwright image with
browsers pre-baked; npm install still pins @playwright/test from tests/e2e, and
the image tag is kept in lockstep with that version. Verified the exact
create + docker cp + start flow launches the baked browser with no download.

The walking-skeleton e2e timed out waiting for the Keycloak login form
(`#username`). Root cause: in the compose 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 undefined. angular-auth-
oidc-client needs SubtleCrypto to build the PKCE code challenge, so
`authorize()` threw ("Cannot read properties of undefined (reading 'digest')")
and the login redirect never fired.
Production serves the portal over HTTPS, where this works. Instead of
terminating TLS in the throwaway e2e stack, tell Chromium to treat the origin
as secure via --unsafely-treat-insecure-origin-as-secure. The flag is only
honoured by the full Chromium build (new headless), not Playwright's default
headless-shell, so pin channel: 'chromium'.
Verified against a minimal in-network stack (keycloak + self-service): login
redirect now reaches the Keycloak form, and the full login → token exchange →
authenticated portal renders with no console errors.

Record the workspace/tooling decisions (pnpm, Nx scoped to apps/+libs/, Vitest,
no @nx/docker, no Nx Cloud, Gitea-only) and a demo note for running the placeholder
app. NL DS deferred to S-08c.
