Add typed service contracts (Protocols + frozen DTOs) in shared/contracts/ for cross-domain communication. Each domain exposes a service interface (BlogService, CalendarService, MarketService, CartService) backed by SQL implementations in shared/services/. A singleton registry with has() guards enables composable startup — apps register their own domain service and stubs for absent domains. Absorbs glue layer: navigation, relationships, event handlers (login, container, order) now live in shared/ with has()-guarded service calls. Factory gains domain_services_fn parameter for per-app service registration. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
