After applying the decision, BeoordeelRegistratie finds the open Beoordelen task for the registration and completes it with the besluit so the workflow advances (ADR-0013). No open task → the decision still stands (completes nothing). DI already provides IUserTaskClient (S-12b). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
