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).
