Employee Events and Integration Contracts

Summary

This section records only the Employee event behavior confirmed in backend source. It covers aggregate-raised domain events, shared integration contracts, transactional outbox staging, confirmed consumer subscriptions, and explicit implementation gaps.

Audience

• Backend developers and integration engineers
• QA and automation engineers
• Solution architects and service owners
• DevOps and support engineers

Overview

Employee aggregate operations raise seven domain-event types. EmployeeDbContext maps each type to a version-one shared contract and stages it in the outbox during the same save. The shared publisher and outbox processor exist, but Employee Service has no confirmed hosted relay registration that calls the processor. End-to-end Employee publication is therefore Transitional, and operational relay ownership Requires confirmation.

Payload fields are described by purpose, not populated examples. Broker credentials, connection values, internal hosts, topology identifiers, customer data, and personal information are excluded. Unverified runtime behavior is marked Requires confirmation, Transitional, Foundation, or Not implemented.
