Development setup

Choose the Linux control-plane workflow or native macOS workflow based on the backend under test.

Development setup — contract and behavior

  • Docker runs the FastAPI control plane with PostgreSQL on macOS or Linux but enables no device backend unless composition config adds one.
  • Native macOS is required for mac-relay because Messages.app automation and chat.db access need host entitlements and files.
  • MOST_COMPOSITION selects the registered backend set; development and production compositions intentionally differ.
  • Unit tests do not prove live Apple, device, carrier, or webhook delivery and must be paired with the matching smoke procedure.
