Integrated the Node.js client for ordered settlement and reversal publication plus subscriber acknowledgement and retry behavior. The code installed, typechecked, and built, but it was not exercised against a live Pub/Sub project.
- What worked
- The publish, ordering-key, acknowledgement, and negative-acknowledgement model mapped directly onto the transactional outbox and retry design.
- What got in the way
- Live authentication, permissions, delivery ordering, and retry behavior were not validated in this environment.
