The BIG Domain Service Api wires the use cases and the hosted job worker:
POST /registrations creates the aggregate and starts the registratie process,
returning 202 with a location; GET /registrations/{id} reads the aggregate so
the eventually-opened zaak URL can be observed (ADR-0009). The Workflow Client
is registered once behind both Flowable ports; the ACL client and in-memory
store complete the wiring. Verified against a live flowable-rest: submit starts
a parked process and the worker polls it.

FlowableWorkflowClient speaks flowable-rest's REST API (Basic auth): start a
registratie process with the registrationId variable, acquire OpenZaakAanmaken
external-worker jobs and parse their registrationId, complete a job with the
zaakUrl variable — the contract verified against a live engine. AclHttpClient
POSTs the bsn to the ACL and returns the zaak URL. InMemoryRegistrationStore is
a concurrent-dictionary upsert. OpenZaakJobProcessor drains parked jobs, opening
a zaak per job and completing it, leaving failures for redelivery; OpenZaakJobPump
is the hosted polling shell that drives it on an interval (ADR-0009).

Failing infrastructure unit tests (stub HttpMessageHandler, fakes):
- FlowableWorkflowClient starts a process with the registrationId variable and
returns the instance id; acquires OpenZaakAanmaken jobs (topic/workerId/lock)
and parses their registrationId; completes a job with the zaakUrl variable —
request URIs match flowable-rest's service/ and external-job-api/ paths.
- AclHttpClient POSTs the bsn to the ACL and returns the zaak URL.
- InMemoryRegistrationStore saves/reads/upserts by id.
- OpenZaakJobProcessor acquires, opens a zaak, completes the job; leaves a failing
job uncompleted for redelivery; polls harmlessly when idle.
Adapters are stubs so the tests compile and fail on their assertions; the green
commit implements them against the REST contract verified on a live Flowable.

SubmitRegistration creates the aggregate, persists it, starts the registratie
process via the Workflow Client, records the instance id and upserts. OpenZaakWorker
loads the correlated registration, opens a zaak via the ACL, attaches it and saves;
an unknown registration throws (job redelivered), and an already-opened zaak short-
circuits without opening a second one (§8.6).

Failing application-layer tests over fake ports (IWorkflowClient, IAclClient,
IRegistrationStore):
- Submit persists an INGEDIEND registration and starts the registratie process,
recording the instance id — and persists *before* starting, so the worker can
correlate the OpenZaakAanmaken job back to its aggregate (ADR-0009).
- The worker opens a zaak via the ACL and attaches it; an unknown registration
throws (job left for redelivery); a redelivered job is idempotent and opens no
second zaak (§8.6).
Handlers are stubs (no persistence / no ACL call) so the tests compile and fail
on their assertions; the green commit implements them.

Submit requires a bsn and starts the aggregate in INGEDIEND; the started
process-instance id is recorded; AttachZaak stores the ACL's zaak URL,
tolerating a duplicate (at-least-once worker delivery) and rejecting a
conflicting URL, without advancing the status.

Failing unit tests for the Registration aggregate root: a submission starts
in INGEDIEND carrying its bsn, an empty/whitespace/null bsn is rejected, the
started process-instance id is remembered, and attaching the zaak the ACL
opened records its URL idempotently (a conflicting URL is rejected) while the
status stays INGEDIEND.
The aggregate is a stub (no-op mutators, empty bsn) so the tests compile and
fail on their assertions; the green commit implements the invariants.
