## What & why After submitting, the self-service portal held the registration only in in-memory signals, so a **page refresh stranded an in-flight registration** — the reference and its "Documenten aanleveren" / "Trek aanvraag in" actions were lost, with no way back (the reference wasn't in the URL and there was no read endpoint). This is the gap a citizen hit in testing. Now the portal **resumes on load**: - **Domain:** `IRegistrationStore.FindOpenByBsnAsync` (the citizen's non-terminal INGEDIEND/IN_BEHANDELING registration) + `GET /registrations/current?bsn=`. - **BFF:** owner-scoped `GET /self-service/registrations` (bsn from the DigiD token) → the current registration, or **204** when none. Regenerated `services/bff/openapi.json`. - **Frontend:** `registration-page` calls it on init and restores the submitted view (reference + actions); 204 shows the submit form as before. api-client regenerated (orval). Closes #111 ## Definition of Done - [x] Linked issue (#111). - [x] TDD — store `FindOpenByBsnAsync` tests, BFF endpoint tests, an Angular component test (resume-on-load), a Playwright e2e (submit → reload → restored). - [x] Conventional Commits referencing #111. - [ ] CI green — validated locally (below); runner CI running. - [x] `docker compose up` reaches green health — fresh stack + full e2e (3 specs) green. - [x] Docs — `docs/synthetic-data.md` (new e2e users). - [ ] ADR — N/A (follows existing BFF/domain patterns; no boundary change). - [ ] Demo note — the flow is unchanged for the demo; no new demo-script section (happy to add one if wanted). ## Verified locally - Unit: Big 141 (+7 store tests), Bff 36 (+3 endpoint tests), all suites green. - Frontend: 12 self-service component tests (incl. resume-on-load); lint + build green. - **e2e (fresh CI stack): all 3 specs pass** — `registration`, `resume`, `withdrawal` (29.5s, single worker). - Mutation: domain **91.04%**, bff **100%** (break 90%). `make lint` clean. ## Notes for reviewers - **Shared-stack isolation:** resume-on-load restores any open registration for the logged-in bsn, so the self-service e2e specs can no longer share `jan-burger` (the verify-* API checks submit as `jan-burger`/`123456782` before the e2e). Each spec now has its own DigiD citizen (`emma`/`sanne`/`lars`-burger); `jan-burger` stays the documented citizen for the verify checks. This is the fix for the two intermittent e2e failures seen during development. - **Scope:** resumes the current **in-flight** registration only (terminal ones aren't resumed), per the issue's out-of-scope note.
