-## S-11 — Withdrawal: "trek aanvraag in" (#12, ADR-0014)
-
-A zorgprofessional can withdraw their own still-open registration from the self-service portal. The
-withdrawal is owner-scoped (the BFF forwards the DigiD token's bsn; the domain only lets the owner
-withdraw) and cancels the running workflow via a BPMN message event, so the case leaves the
-behandelaar's werkbak.
-
-```text
-# 1. Log in and submit at the self-service portal (http://localhost:8140/, jan-burger / test123),
-#    note the "Referentie" on the confirmation.
-# 2. Click "Trek aanvraag in" → the page confirms the registration is ingetrokken.
-# 3. In the behandel werkbak (http://localhost:8142/, merel-behandelaar) the registration no longer
-#    appears — its Beoordelen task was cancelled.
-```
-
-**The path:** self-service → BFF `POST /self-service/registrations/{id}/withdraw` (DigiD, owner-scoped)
-→ domain sets INGETROKKEN + correlates the `RegistratieIngetrokken` message to the process → the
-interrupting boundary event ends it → the werkbak drops the case.
-
-> DigiD submit → trek aanvraag in → ingetrokken is the Playwright happy path
-> (`tests/e2e/withdrawal.spec.ts`); the owner-scoping + workflow cancellation are covered by the
-> `Een registratie intrekken` acceptance scenarios and the domain live check.

-## Self-service withdrawal: "trek aanvraag in" (S-11c, #12)
-
-The submit confirmation grows a **"Trek aanvraag in"** action so a zorgprofessional can withdraw the
-registration they just submitted (`apps/self-service`, on the existing `RegistrationPage`).
-
-- **Keyed by the reference, owner-scoped at the BFF.** The button calls the generated
-  `postSelfServiceRegistrationsIdWithdraw(reference)` with the reference the submit returned. The
-  DigiD token (attached by the interceptor) carries the bsn the BFF forwards; the domain only lets
-  the owner withdraw (a mismatch is 404). No extra identity is entered in the UI.
-- **Same confirm-and-surface pattern as submit.** A secondary-action button; on success the page
-  switches to an ingetrokken confirmation; a failure is surfaced (`role="alert"`) and the action
-  stays available to retry — mirroring how submit handles its failure rather than swallowing it.
-- **Testing.** Component tests (`@testing-library/angular`, mocked BFF) cover the button appearing
-  after submit, the reference being passed, the ingetrokken confirmation, and the failure path; the
-  browser round-trip is `tests/e2e/withdrawal.spec.ts`.
