test(e2e): provide documents on the live self-service tab after the zaak opens (refs #102)

The process only parks at WachtOpDocumenten once the OpenZaak worker has opened the
zaak, so providing documents immediately after submit raced the wait and no-op'd.
Check the openbaar INGEDIEND row on a second page (proving the zaak is open, hence
the process is at the wait) while the self-service tab keeps its submitted state,
then provide documents there — unblocking the werkbak.

 ### S-10 · Document upload + boundary timer for document timeout (Flow 2)
 
-**Outcome:** BPMN extended with a "wacht op documenten" user task with a 30-day boundary timer. Self-service portal supports diploma upload. On timeout the case is cancelled.
+Split (issue #11 closed) into two independently-demoable slices per §13 — the original spanned six net-new surfaces including a new ZGW boundary:
 
-**Acceptance:** BDD scenarios for both branches; integration tests for the timer firing.
+#### S-10a · Document-wait task + 30-day timeout cancellation + provision trigger — #102
+
+**Outcome:** BPMN gains a `WachtOpDocumenten` user task with a 30-day (P30D) interrupting boundary timer. On timeout the case is cancelled — the timer runs to a dedicated cancel end-event and the domain aggregate moves to a new terminal status `Verlopen` via an external-worker (mirrors S-14 escalation / S-11 withdrawal). "Documents received" is wired end-to-end (domain endpoint + BFF + a "Documenten aanleveren" button on the self-service page) so the walking-skeleton e2e stays green — but the document is **not yet stored** in ZGW; that is S-10b.
+
+**Acceptance:** BDD both branches (documents-in-time vs timeout-cancel); live timer-fire via the management-API "move" idiom; the registration e2e provides documents before the behandelaar step.
+
+#### S-10b · Real diploma upload stored via the ACL Documenten API — #103
+
+**Outcome:** the self-service "Documenten aanleveren" action becomes a real file upload; the document is stored in the ZGW Documenten (DRC) API and related to the zaak, with all document calls routed through the ACL (§8.1), and the zaak is set to a cancellation status on timeout expiry. Builds on the S-10a trigger/wait. Depends on #102.
+
+**Acceptance:** ACL Documenten gateway integration test; Playwright e2e uploads a real document; the openbaar/zaak reflects the stored document.

+# ADR-0015: Beoordeling escalation reassigns via an external-worker task
+
+- **Status:** Accepted
+- **Date:** 2026-07-17
+- **Deciders:** Respellion engineering
+- **Relates to:** S-14 (#15); proposal #98. Builds on ADR-0009 (external-task worker / Workflow
+  Client), ADR-0013 (behandel-portal wiring, the `Beoordelen` user task), ADR-0014 (the boundary-event
+  pattern on `Beoordelen`).
+
+## Context
+
+S-14 escalates a beoordeling that a behandelaar does not pick up in time: after 14 days the case must
+move to the `teamlead` role (PRD §5, flow 5). The `Beoordelen` user task already exists, claimable by
+the `behandelaar` candidate group; the teamlead role is seeded in the medewerker realm.
+
+Two forces shape this.
+
+1. **The task must stay open.** Escalation changes *who may claim* an unclaimed beoordeling, not the
+   work itself — so the timer must be **non-interrupting**: the `Beoordelen` task keeps running while
+   escalation happens alongside it.
+2. **Reassigning an open task's candidate group needs code.** Flowable cannot rewrite the candidate
+   groups of an already-open user task from BPMN XML alone — that requires either a Java delegate/listener
+   embedded in the engine, or an out-of-process actor driving the REST API. The repository has held a
+   "stock Flowable image, no custom jars; the Workflow Client is the only code that talks to Flowable
+   (§8.2)" posture since ADR-0009.
+
+## Decision
+
+**A non-interrupting `P14D` boundary timer on `Beoordelen` fires an external-worker task
+(`BeoordelingEscaleren`); the Workflow Client reassigns the still-open `Beoordelen` task from the
+behandelaar group to teamlead.**
+
+- **Modelled in BPMN, driven by an external worker.** The timer routes a parallel token to an
+  `external-worker` service task on the `BeoordelingEscaleren` topic, ending at a dedicated "Beoordeling
+  geëscaleerd" end event. The model owns *when* escalation happens; the Workflow Client — the only code
+  that talks to Flowable (§8.2) — owns *how* the reassignment is applied, exactly as `OpenZaakAanmaken`
+  delegates the ZGW call (ADR-0009). No custom code runs inside Flowable.
+- **Reassignment is a candidate-group swap.** The escalation worker finds the still-open `Beoordelen`
+  task in the escalating instance (task query by `processInstanceId` + `taskDefinitionKey`), adds
+  `teamlead` as a candidate group via the task identity links, then removes `behandelaar`. The task now
+  belongs to the teamlead; its history and variables are untouched.
+- **Best-effort, mirroring beoordeling and withdrawal.** If the task is no longer open — the behandelaar
+  completed it in the window before the timer fired — the reassignment is a no-op. A failed reassignment
+  leaves the escalation job un-completed so Flowable redelivers it (§8.6), consistent with the
+  `OpenZaakAanmaken` worker.
+- **Segregated interface.** The escalation methods live on `IBeoordelingEscalatieClient`, separate from
+  the `OpenZaakAanmaken` worker's `IExternalWorkerClient`, so the OpenZaak worker never sees escalation
+  (interface segregation). Both are implemented by the one `FlowableWorkflowClient`.
+
+## Consequences
+
+**Positive**
+
+- The escalation trigger is visible in `registratie.bpmn`; Flowable stays a stock image, and the
+  Workflow Client remains the sole Flowable client (§8.2 upheld, not bent).
+- Reuses the external-worker mechanics (topic acquire/complete, hosted pump, per-tick scope,
+  redelivery-on-failure) wholesale — the new code is one client capability, one processor, one pump.
+- Escalation latency is bounded by the worker's poll interval (seconds) — negligible against a 14-day
+  timer.
+
+**Negative / costs**
+
+- Escalation is two REST hops (add teamlead, remove behandelaar) rather than one atomic update; between
+  them the task is briefly claimable by both groups. Harmless at these volumes, and the pair is idempotent
+  on redelivery.
+- The Flowable identity-link and management-job REST shapes are validated live (verify-domain fires the
+  timer early via the management API), not in the Workflow Client's unit tests, which stub the HTTP
+  exchange and assert only the request shape — consistent with ADR-0009 and ADR-0014.
+
+## Alternatives considered
+
+- **Flowable timer/task listener (Java delegate).** Reassign in-engine when the timer fires. Rejected:
+  it needs a custom jar in Flowable, breaking the stock-image, REST-only posture and adding a build/deploy
+  surface to the engine for no capability the external-worker route lacks.
+- **Interrupting timer that re-creates the task for teamlead.** Cancel `Beoordelen` and start a fresh
+  teamlead task. Rejected: it loses the task's identity/history and complicates correlation, where a
+  candidate-group swap on the same task expresses "the same work, now the teamlead's" directly.

+# ADR-0016: Diploma eligibility is a DMN evaluated inline as a BPMN DMN service task
+
+- **Status:** Accepted
+- **Date:** 2026-07-17
+- **Deciders:** Respellion engineering
+- **Relates to:** S-13 (#14); proposal #100. Builds on ADR-0009 (external-task worker / Workflow
+  Client), ADR-0014/0015 (the boundary-event and routing constructs on the registratie process).
+
+## Context
+
+S-13 adds flow 4: a foreign diploma must get an extra CBGV-advies assessment before beoordeling
+(PRD §5). The eligibility decision — domestic goes straight to beoordeling, foreign routes through
+CBGV-advies — needs a home. The Flowable REST app bundles a DMN engine, and the same
+`repository/deployments` machinery that deploys `registratie.bpmn` can deploy a `.dmn`. §8.2 makes
+the Workflow Client the only code that talks to Flowable; the PRD frames the workflow as "BPMN + DMN
+governing the registration workflow" (Flowable as a peer orchestration module).
+
+The issue's wording ("a DMN decision table evaluated by the Domain Service via Workflow Client")
+suggests the domain reaches into Flowable's DMN API to evaluate the decision and feeds the result
+back. That is one option; it is not the only one, and it is not the cleanest.
+
+## Decision
+
+**The diploma-eligibility DMN is deployed to Flowable and evaluated inline by the registratie process
+as a DMN service task (`flowable:type="dmn"`); an exclusive gateway routes on its output. The domain's
+only new job is to carry the diploma origin and pass it into the process as a start variable.**
+
+- **The decision lives in the workflow.** `workflows/diploma-eligibility.dmn` maps `diplomaOrigin`
+  → `route` (`Buitenlands` ⇒ `CBGV_ADVIES`, otherwise `DIRECT`). A DMN service task
+  (`flowable:type="dmn"`, `decisionTableReferenceKey=diploma-eligibility`) runs it between
+  `OpenZaakAanmaken` and `Beoordelen`, and an exclusive gateway sends `CBGV_ADVIES` through a new
+  `CBGVAdvies` user task before `Beoordelen`, `DIRECT` straight there. (A `businessRuleTask` would
+  bind Flowable's legacy Drools/KIE implementation, which `flowable-rest` does not bundle — its parse
+  handler throws `NoClassDefFoundError` at deploy time; the DMN service task is the supported route.)
+- **The domain carries the input, not the decision.** The `Registration` aggregate gains a
+  `DiplomaOrigin` (Binnenlands/Buitenlands); `SubmitRegistration` passes it to
+  `StartRegistrationProcessAsync`, which sets it as the `diplomaOrigin` start variable. The domain
+  never evaluates the DMN and never learns the route — that is the process's concern.
+- **Deployed as its own DMN-engine deployment, separate from the BPMN.** The DMN is version-controlled
+  in `workflows/` and `flowable-init` deploys it to the DMN engine via the `dmn-api`
+  (`/dmn-api/dmn-repository/deployments`), while `registratie.bpmn` goes to the process engine via
+  `/service/repository/deployments`. Two things were learned the hard way here (both cost a CI cycle):
+  (1) `flowable-rest` does **not** cascade a `.dmn` bundled inside a process `.bar` into the DMN engine
+  — the resource is stored but no decision is created, so the service task fails at runtime with
+  `FlowableObjectNotFoundException: No decision found for key`; the DMN must go through `dmn-api`.
+  (2) Flowable's DMN XML converter rejects an XML comment placed between the `<?xml?>` declaration and
+  the root `<definitions>` element (`XMLStreamReader not in START_DOCUMENT or START_ELEMENT state`),
+  unlike its BPMN converter — so the DMN's documentation comment lives *inside* `<definitions>`.
+  With the decision present in the DMN repository, the process's DMN service task resolves it across
+  deployments by key (verified live), so no shared parent deployment id is needed.
+
+## Consequences
+
+**Positive**
+
+- The eligibility rule is a first-class, inspectable workflow artefact (matching the PRD's BPMN+DMN
+  framing); business users can read/adjust the decision table without touching domain code.
+- §8.2 stays clean: the Workflow Client remains the only code talking to Flowable, and the decision
+  runs inside the process the client already started — no domain→Flowable round-trip for a decision.
+- The domain change is minimal and additive: one value on the aggregate, one start variable.
+
+**Negative / costs**
+
+- Deviates from #14's literal "evaluated by the Domain Service via Workflow Client" wording (noted on
+  the issue). The outcome — DMN decides eligibility, foreign diplomas get the CBGV step — is unchanged.
+- The DMN and its service-task wiring are validated live (verify-domain drives a foreign
+  registration through CBGV-advies and a domestic one straight to beoordeling, exercising both
+  branches), not in unit tests — consistent with ADR-0009/0014/0015. The domain unit/acceptance tests
+  cover only that the origin is carried into the process.

+# ADR-0017: A document-wait task with a 30-day interrupting timer cancels the registration
+
+- **Status:** Accepted
+- **Date:** 2026-07-20
+- **Deciders:** Respellion engineering
+- **Relates to:** S-10a (#102); proposal #104; split from S-10 (#11). Builds on ADR-0009 (external-task
+  worker / Workflow Client), ADR-0014 (withdrawal cancels the process), ADR-0015 (beoordeling
+  escalation — the boundary-timer + external-worker pattern), ADR-0016 (diploma-eligibility DMN).
+
+## Context
+
+Flow 2 (PRD §5) requires the citizen to supply documents (their diploma) after submitting. The
+registratie process must park waiting for those documents and, if they do not arrive within 30 days,
+cancel the case. S-10 was split (§13): **S-10a** is this workflow/timeout spine (backend only);
+**S-10b** wires the actual upload (portal → BFF → domain → ACL → Documenten API) that completes the
+wait. This ADR records the spine: where the wait sits, how the timeout cancels, and how the domain
+aggregate stays in sync.
+
+## Decision
+
+**A `WachtOpDocumenten` user task is inserted immediately after `OpenZaakAanmaken`, carrying an
+`cancelActivity="true"` (interrupting) `P30D` boundary timer. "Documents received" completes the task
+and the process continues into the diploma-eligibility routing; on timeout the timer cancels the task,
+runs a `RegistratieVerlopen` external-worker task, and ends the process at `endVerlopen`. A domain
+worker expires the correlated aggregate to a new terminal status `Verlopen`.**
+
+- **Where the wait sits.** Right after the zaak is opened, before the diploma-eligibility DMN: the zaak
+  exists, then the process waits for documents; on receipt it continues to the DMN routing → Beoordelen
+  (ADR-0016). The wait gates the whole assessment, so it precedes the routing rather than sitting
+  between the gateway and Beoordelen.
+- **Interrupting timer, mirroring the existing constructs.** Unlike the S-14 escalation timer
+  (non-interrupting — the Beoordelen task stays open), this timer is interrupting: when it fires the
+  wait token is consumed and the case is cancelled, like the S-11 withdrawal boundary (ADR-0014). The
+  timeout branch runs a `RegistratieVerlopen` external-worker task (topic mirrors
+  `OpenZaakAanmaken`/`BeoordelingEscaleren`) → `endVerlopen`.
+- **The domain stays authoritative.** The `RegistratieVerlopen` job carries the `registrationId`; the
+  `RegistratieVerlopenProcessor` drains it and the `ExpireRegistrationWorker` loads the aggregate and
+  calls `Registration.Expire()`, moving it to the new terminal status `Verlopen`. This keeps the
+  aggregate — which the projection/openbaar view reads — the source of truth, exactly as escalation and
+  withdrawal do. Idempotent per §8.6: a redelivered job whose aggregate is already `Verlopen` completes
+  without persisting again; an unknown registration throws so the job is redelivered.
+- **Documents-in-time transition.** `IWorkflowClient.CompleteDocumentWaitAsync(processInstanceId)`
+  completes the `WachtOpDocumenten` task (the Workflow Client remains the only code that talks to
+  Flowable, §8.2). It is best-effort — a no-op if the instance already left the wait (continued, or
+  timed out). The trigger is wired end-to-end in S-10a: a `ProvideDocuments` application use case behind
+  an owner-scoped domain endpoint `POST /registrations/{id}/documents`, a BFF passthrough
+  `POST /self-service/registrations/{id}/documents` (bsn from the DigiD token), and a "Documenten
+  aanleveren" action on the self-service page — so the walking-skeleton e2e stays green (a registration
+  can still reach the behandelaar). **S-10b replaces the stub trigger with a real file upload stored in
+  the ZGW Documenten (DRC) API via the ACL**; the completion of the wait is unchanged.
+  - *Why the trigger lives here, not in S-10b:* inserting the `WachtOpDocumenten` gate without any way
+    to pass it breaks the submit→beoordeling e2e (a merge gate). Splitting "gate" from "means to pass
+    the gate" across slices would leave `main` red, so S-10a owns both; S-10b is purely the ZGW storage
+    behind the same action.
+
+## Consequences
+
+**Positive**
+
+- The wait/timeout is a first-class workflow construct that reuses the boundary-timer + external-worker
+  pattern already proven by S-14, so the domain change is small and additive: one terminal status, one
+  worker trio (worker + processor + pump), one Workflow Client method.
+- §8 stays clean: the Workflow Client is still the only Flowable caller, and no new ZGW boundary is
+  introduced in S-10a.
+- The timeout is verified live (verify-domain fires the P30D timer via the management-API "move" idiom
+  and asserts the domain reaches `Verlopen`), consistent with ADR-0009/0014/0015.
+
+**Negative / costs**
+
+- Every registration now parks at `WachtOpDocumenten` before Beoordelen, so the other flows must supply
+  documents first: the live-check blocks (S-11/S-12b/S-13/S-14) complete the task via Flowable, and the
+  registration e2e clicks "Documenten aanleveren". A small, explicit step, but it touches every path
+  through the process.
+- On expiry S-10a cancels the *process* and marks the aggregate `Verlopen` but does **not** set the ZGW
+  *zaak* to a cancellation status — that needs a new ACL method + statustype seeding, which overlaps
+  S-10b's ACL/infra work. Deferred to S-10b (or a follow-up); noted here as the S-10a/S-10b boundary.
+- Withdrawing while parked at `WachtOpDocumenten` marks the aggregate `Ingetrokken` but does not cancel
+  the process (the withdrawal message boundary is on `Beoordelen`); the timeout worker tolerates this
+  by no-op'ing on an already-resolved aggregate. Extending withdrawal to the wait state is a follow-up.
+
+## Alternatives considered
+
+- **Pure-BPMN cancellation (timer → end event, no worker).** Rejected: the domain aggregate would then
+  be out of sync with the cancelled process, and the openbaar/projection view reads the aggregate's
+  status — the case would still look open.
+- **Wait task between the gateway and Beoordelen.** Rejected: documents gate the whole assessment
+  (including the CBGV-advies routing), so the wait belongs before the DMN, not after it.
+- **A dedicated timeout status per branch vs. reusing an open-state guard.** `Expire()` reuses the same
+  `RequireOpenForDecision` guard as withdrawal/decision, so only an `INGEDIEND`/`IN_BEHANDELING`
+  registration can lapse and the terminal states stay mutually exclusive — no new guard logic.

+## 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.
+
+## S-14 — Beoordeling escalation: 14 days unclaimed → teamlead (#15, ADR-0015)
+
+A beoordeling a behandelaar does not pick up within 14 days escalates to the teamlead. A
+non-interrupting boundary timer on the `Beoordelen` task fires a `BeoordelingEscaleren` external task;
+the domain's escalation worker reassigns the still-open task's candidate group from `behandelaar` to
+`teamlead`, so it moves from the behandelaar werkbak into the teamlead's. The `Beoordelen` task keeps
+its identity throughout — only who may claim it changes.
+
+The timer is 14 days, so the demo fires it early through Flowable's management API (exactly what the
+verify-domain check automates):
+
+```bash
+# 1. Submit at the self-service portal (http://localhost:8140/, jan-burger / test123). The case
+#    parks at Beoordelen, visible in the behandelaar werkbak (http://localhost:8142/, merel-behandelaar)
+#    but NOT claimed.
+#
+# 2. Find the parked instance and its Beoordelen task, then fire the boundary timer early:
+FL=http://localhost:8090/flowable-rest/service
+PID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \

+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["processInstanceId"])')
+TID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \

+```
+
+**The path:** BPMN non-interrupting `P14D` boundary timer on `Beoordelen` → `BeoordelingEscaleren`
+external task → domain escalation worker (`BeoordelingEscalatiePump`) → Workflow Client swaps the task's
+candidate group behandelaar → teamlead (§8.2).

+
+## S-13 — Diploma-eligibility: foreign diplomas route through CBGV-advies (#14, ADR-0016)
+
+A registration's diploma origin decides its route. A DMN service task in the registratie
+process evaluates the `diploma-eligibility` decision on the `diplomaOrigin` start variable: a
+**foreign** (Buitenlands) diploma is routed through an extra **CBGV-advies** user task before
+beoordeling; a **domestic** (Binnenlands) one goes straight to beoordeling. The decision lives in the
+DMN, not in code — a beheerder can read and adjust the decision table directly.
+
+The self-service portal's eIDAS→foreign wiring is a later slice; for now the origin is submitted to
+the domain directly, so the demo drives it through the domain endpoint:
+
+```bash
+# 1. Submit a foreign-diploma registration to the domain (note the returned Location/reference):
+DOM=http://localhost:8080   # domain service
+curl -s -i -X POST "$DOM/registrations" -H 'Content-Type: application/json' \
+  -d '{"bsn":"123456782","diplomaOrigin":"Buitenlands"}' | grep -i '^location:'
+#
+# 2. Once the zaak is opened, the process first parks at WachtOpDocumenten (S-10a); complete that task
+#    (documents received) — then it parks at the CBGV-advies task (NOT Beoordelen). In Flowable:
+FL=http://localhost:8090/flowable-rest/service
+curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d '{"processDefinitionKey":"registratie","taskDefinitionKey":"CBGVAdvies"}' | python3 -m json.tool
+#
+# 3. Complete the CBGV-advies task; the case then advances to the regular Beoordelen task:
+TID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d '{"processDefinitionKey":"registratie","taskDefinitionKey":"CBGVAdvies"}' \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+curl -s -u rest-admin:test -X POST "$FL/runtime/tasks/$TID" \
+  -H 'Content-Type: application/json' -d '{"action":"complete"}'
+# A domestic submission (default, or "Binnenlands") skips CBGV-advies and parks straight at Beoordelen.
+```
+
+**The path:** domain sets the `diplomaOrigin` start variable → registratie process DMN
+DMN service task sets `route` → exclusive gateway → foreign: `CBGVAdvies` user task → `Beoordelen`;
+domestic: `Beoordelen` directly (§8.2, ADR-0016).
+
+> The domestic/foreign paths are covered by the `Een diploma op herkomst routeren` acceptance
+> scenarios and unit tests (the origin is carried into the process); the DMN decision and the
+> foreign→CBGV routing are asserted live by the verify-domain check.
+
+## S-10a — Document wait + 30-day timeout cancels the registration (#102, ADR-0017)
+
+After the zaak is opened the registratie process parks at a **WachtOpDocumenten** user task, waiting
+for the citizen's documents (their diploma). Two things can happen:
+
+- **Documents arrive in time** → the task completes and the process continues to the diploma-eligibility
+  routing (S-13) → beoordeling.
+- **30 days pass with no documents** → an interrupting `P30D` boundary timer cancels the wait, runs the
+  `RegistratieVerlopen` external task, and the domain expires the registration to the terminal status
+  **VERLOPEN** (the case is cancelled).
+
+The "documents received" trigger is wired end-to-end in S-10a: the self-service page shows a
+**"Documenten aanleveren"** button after submit (portal → BFF → domain → completes the wait). S-10b
+turns that into a real file upload stored in the ZGW Documenten API via the ACL. The timeout branch is
+demonstrated by firing the 30-day timer early via the management API.
+
+```bash
+DOM=http://localhost:8080                      # domain service
+FL=http://localhost:8090/flowable-rest/service # flowable-rest
+
+# 1. Submit a registration; once the zaak is opened it parks at WachtOpDocumenten:
+curl -s -i -X POST "$DOM/registrations" -H 'Content-Type: application/json' \
+  -d '{"bsn":"123456782"}' | grep -i '^location:'          # note the /registrations/<id> reference
+WQ='{"processDefinitionKey":"registratie","taskDefinitionKey":"WachtOpDocumenten"}'
+
+# 2a. Documents-in-time: complete the WachtOpDocumenten task → the process advances to beoordeling.
+TID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d "$WQ" | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+curl -s -u rest-admin:test -X POST "$FL/runtime/tasks/$TID" \
+  -H 'Content-Type: application/json' -d '{"action":"complete"}'
+
+# 2b. Timeout: instead of completing it, fire the 30-day timer early via the management API. Find the
+#     instance's timer job, "move" it to executable; the async executor fires the interrupting event.
+PID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d "$WQ" | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["processInstanceId"])')
+JID=$(curl -s -u rest-admin:test "$FL/management/timer-jobs?processInstanceId=$PID" \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+curl -s -u rest-admin:test -X POST "$FL/management/timer-jobs/$JID" \
+  -H 'Content-Type: application/json' -d '{"action":"move"}'
+#     The RegistratieVerlopen worker then expires the aggregate — read it back as VERLOPEN:
+curl -s "$DOM/registrations/<id>"   # → {"status":"Verlopen", ...}
+```
+
+**The path:** registratie process parks at `WachtOpDocumenten` → documents received completes it (→
+routing → `Beoordelen`), OR the `P30D` interrupting timer fires → `RegistratieVerlopen` external task
+→ domain worker expires the aggregate to `Verlopen` → `endVerlopen` (§8.2, ADR-0017).
+
+> Both branches are covered by the `Een documenttermijn laten verlopen` acceptance scenarios (worker +
+> aggregate) and unit tests; the wait completion and the 30-day timer firing are asserted live by the
+> verify-domain check.
