Multi-Tenant Patterns

Keep project data isolated while sharing the event-sourced backend.

The Starter Kit inherits multi-tenancy from the backend event store:

• Every authenticated request includes the project ID and API key headers that the backend projectors expect.
• Read models in the Cloud API scope responses by project, so your UI receives only the data associated with the keys in use.
• When extending functionality, continue emitting events and projecting read models per the guidance in devkit4ai/backend-api/SPECS.md to preserve isolation.
