Workflow Approval Events

Summary​

Approval emits a task-level event and may also emit task-created events for the next stage or a terminal completion event.

Approval event flow​

Ordering within aggregate​

The approval event is queued before next-stage task-created or completion events during one command. Outbox insertion iterates the aggregate event list in that order, but no end-to-end ordering guarantee is implemented.

Consumers​

No verified subscriber consumes approval or completion events.

Requires Confirmation​

Downstream approval consumers, ordering requirements and notification behavior require confirmation.
