Application Layer

Summary

Command services coordinate aggregates, tenant/actor context, evidence, integrations, results, and saves. Queries compose tenant-filtered reads and map DTOs. No validator framework or mediator pipeline is present; outbox mapping occurs on save.

Audience

Backend and frontend developers, QA, architects, DevOps, support, and new engineers.
