Employee Future Evolution

Summary​

Source comments and placeholder guidance identify several extension seams, but they do not constitute approved roadmap commitments. Every future change requires product and architecture confirmation.

Audience​

  • Backend developers and QA engineers
  • DevOps engineers, solution architects, security engineers, and product owners

Purpose​

Record only architectural direction explicitly present in source while preventing speculative behavior from being presented as planned delivery.

Confirmed extension seams​

  • Search provider replacement: the Application search port is provider-agnostic, and source comments explicitly describe replacing the current PostgreSQL adapter with an alternate search provider without changing callers.
  • Timeline storage separation: the timeline repository is separate from the aggregate repository, and source comments identify possible movement to a dedicated append-only/event-oriented store at scale.
  • Application behaviors: the Behaviors placeholder names validation, audit, idempotency, telemetry, and transaction concerns as intended cross-cutting behavior candidates.
  • Service-local contracts: the Contracts placeholder reserves a location for Employee-owned public contracts while cross-service integration contracts remain shared.
  • Gateway cutover: Gateway configuration and compatibility routing establish incremental movement from monolith ownership toward Employee Service.

Requires confirmation​

  • Whether and when to implement an alternate search provider.
  • Whether the timeline will move to a dedicated store.
  • Adoption of a mediator or custom dispatcher and consolidation of duplicate application styles.
  • Hosted Employee outbox relay ownership and operating model.
  • Fine-grained authorization completion and compatibility-context retirement.
  • Attendance synchronization and broader downstream projections.
  • Separate readiness/liveness checks, dependency health, metrics, caching, and load testing.
  • Final compatibility-route retirement and production cutover milestones.

No future API, database design, event payload, deployment target, or delivery date is asserted.
