Workflow Domain Event Catalog

Audience

Developers, QA, support, architects and integration reviewers.

Summary

This authoritative catalog contains exactly six Workflow domain-event types. All inherit generated event identity/time from WorkflowDomainEvent.

Framework

A lightweight in-process domain-event abstraction queues events on aggregate roots. There is no mediator/dispatcher; DbContext reads queued events during save, maps supported types and clears them.

Requires Confirmation

Whether future in-process handlers or definition/delegation events are intended requires confirmation.
