## What & why The behandel werkbak now **refreshes itself** while it is open, so a registration that reaches beoordeling after the behandelaar opened the page shows up on its own — no reload. `interval(WERKBAK_REFRESH_MS)` (5 s) re-reads the existing BFF endpoint, scoped to the page with `takeUntilDestroyed()`. A *background* read leaves the rows and states on screen alone until it has an answer, so a tick never flashes the loading state over rows being read and one failed poll never swaps the list for the error alert; a read that comes back also clears an earlier failure, so the view recovers on its own rather than needing the very reload this slice removes. No new endpoint, dependency or server-side state, and no service boundary moves — rxjs and `GET /behandel/werkbak` are both already here. **ADR-0032** records why polling rather than a pushed stream: nothing notifies the BFF either, so SSE/WebSockets would poll the domain *inside* the BFF for the same freshness, plus connection lifecycle, nginx buffering and a stateful BFF. Proposal: #163. Closes #162 ## 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 #162`). - [ ] CI green — all Gitea Actions jobs. - [x] `docker compose up` from a fresh clone reaches green health checks within 3 minutes (unchanged; only the behandel bundle differs). - [x] Docs updated if behaviour, contracts, or operations changed. - [x] ADR added in `docs/architecture/` (ADR-0032). - [x] Demo note in `docs/demo-script.md` (user-visible). ## Notes for reviewers **The e2e is the real acceptance test, and it took two goes to make it one.** Simply dropping the `staff.reload()` from the happy path proved nothing: the werkbak was visited *after* the documents were supplied, so the row was already there at page load. The spec now logs the behandelaar in **first**, asserts the row is not there yet, and only then has the citizen supply the documents that route it to Beoordelen — so the row can only reach that already-open, never-reloaded page via the refresh. Verified both ways against a live stack: with the interval stubbed out it fails at `Goedkeuren <ref> … element(s) not found` after 30 s; with it, the behandel nginx logs the poll that delivers the row. The page is foregrounded before the assertion because Chromium throttles timers in a hidden tab. **Ceiling (named in the ADR):** a fixed 5 s interval, per open page, that keeps polling in a background tab; each tick costs one Flowable task query plus a store read per open task. Upgrade path: publish task events from the domain, then swap the `interval` for a stream — the endpoint contract and the rendering stay put. Gate on `document.visibilityState` first if request volume is the concern. **Two housekeeping notes, neither blocking:** - #162 is on **no milestone** (DoD item 1). It is portal UX, so it fits neither *Data Governance* nor *Production Posture* cleanly — your call where it lands. - The issue titles itself **S-26**, which already belongs to the self-service resume slice (#111, `BACKLOG.md`). Everything here references **#162**; worth renumbering the title if the S-ids are meant to stay unique. `BACKLOG.md` is untouched for the same reason (it mirrors the active milestone, and this slice is on none).Reviewed-on: #164
register-reference
A reference application demonstrating how to build a Dutch government register (a BIG-style professional register) on top of unforked Common Ground modules — OpenZaak, Open Notificaties, Objecten, Open Klant — with loose coupling, modern workflow tooling, and data-governance ready integration points.
This repository is the runnable companion to Respellion's Foundations playbook entry on Common Ground architecture for non-municipal contexts (CIBG, DUO, RVO, and similar uitvoeringsorganisaties).
Status: under active development. See BACKLOG.md for the current iteration.

The day-to-day operational pages — environment URLs, known issues right now, on-call notes — live in the Gitea Wiki for this repository. The wiki points at docs/ for anything authoritative.
What this application demonstrates
- A BIG-style professional register modelled on Dutch public-sector patterns, with four end-user portals: self-service, openbaar register, behandel-portal, beheer-portal.
- Common Ground modules as upstream peers — never forked, reached only via documented APIs (ZGW, NRC events).
- An Anti-Corruption Layer that confines all ZGW knowledge to one place, so the rest of the codebase stays domain-shaped rather than municipality-shaped.
- BPMN + DMN workflows via Flowable as a separate, swappable module — using the external-task job-worker pattern so BPMN models never reach into OpenZaak.
- A read projection as the public-facing data path, decoupled from the authoritative modules.
- Synthetic data and mock identity (Keycloak realms standing in for DigiD, eHerkenning, eIDAS, and a medewerker IdP) so the whole system runs locally without external dependencies.
- TDD, DDD, BDD, mutation testing, ADRs, and Conventional Commits as enforced defaults — encoded in CI.
- Gitea-native delivery: source, issues, milestones, project boards, releases, container registry, packages, wiki, and Actions.
For the architecture rationale, see docs/PRD.md §3 and docs/architecture/.
Local quickstart
Prerequisites
- .NET 10 SDK (for
make lint/build/unit) - A container engine with Compose v2 — Docker, or rootless Podman (see docs/runbooks/ci.md for the Podman + Compose-provider setup)
make,curl,git- ~4 GB free RAM, ~5 GB free disk (grows as services land)
Clone
git clone git@git.labs.respellion.tech:eho/register-referentie.git
cd register-referentie
Wired today (Iteration 0): only the placeholder BFF exists so far. Get to green in under 10 minutes — run the full check gate, or just the running service:
make ci # lint + build + unit + container smoke — the CI gate
docker compose -f infra/docker-compose.yml up -d --build --wait
curl http://localhost:8080/health # -> Healthy
--wait exits non-zero unless the container reports healthy, so it doubles as the compose-up smoke test. The remaining services and the URLs below land in later slices.
Target service URLs (most land in later slices)
| Service | URL |
|---|---|
| Self-Service portal | http://localhost:4200 |
| Openbaar register | http://localhost:4201 |
| Behandel-portal | http://localhost:4202 |
| Beheer-portal | http://localhost:4203 |
| BFF | http://localhost:8080 |
| OpenZaak | http://localhost:8000 |
| Open Notificaties | http://localhost:8001 |
| Flowable | http://localhost:8080 |
| Keycloak | http://localhost:8180 |
| MkDocs site (after build) | http://localhost:8000/docs/ |

Working in this repository
Source of truth for work: Gitea Issues + Milestones for this repository. BACKLOG.md is a mirror.
Branching: trunk-based. Short-lived branches off main, named <type>/<issue-number>-<short-slug> (e.g. feat/14-acl-default-fill).
Commits: Conventional Commits, referencing the Gitea issue:
feat(acl): default-fill bronorganisatie (refs #14)
The merging PR closes the issue via closes #14 in the squash-commit body.
Pull Requests: the unit of review. Squash-merged. PR template enforces the Definition of Done checklist from CLAUDE.md §3.
Releases: CalVer (YYYY.MM.PATCH), tagged on main, changelog generated by git-cliff, published as a Gitea Release with container images in the Gitea Container Registry.
See CLAUDE.md for the full working agreements, the architectural non-negotiables, and the rules Claude Code follows on every task.
Testing
- Unit tests — dominant. .NET (xUnit) and Angular (Vitest / Testing Library).
- Integration tests — Testcontainers-driven, exercising real OpenZaak, Flowable, NRC.
- Acceptance tests — Gherkin scenarios in
tests/acceptance/, one per user-visible flow. - End-to-end — Playwright, expanding slice by slice from the walking-skeleton happy path.
- Mutation testing — Stryker.NET and Stryker, baseline-ratcheted on
main.
Run everything:
./tools/test-all.sh
Run a focused slice (example):
dotnet test services/acl
Contributing
- Find or open a Gitea issue using one of the templates in
.gitea/ISSUE_TEMPLATE/(slice.md,bug.md,adr-proposal.md). - Assign yourself, move it to "In progress" on the milestone's project board.
- Branch off
main, follow the CLAUDE.md working agreements (TDD: red commit → green commit → refactor commit). - Open a PR using the template, link the issue, ensure the Gitea Actions pipeline is green.
- Squash-merge once approved. The merging commit closes the issue.
If a task pushes against any of the architectural rules in CLAUDE.md §8, stop and open an adr-proposal issue first. That conversation is more important than the code.
