 # Blog App (Coop)
 
-Blog, authentication, and content management service for the Rose Ash cooperative platform. This is the primary "coop" app — it handles Ghost CMS integration, user auth, and admin settings.

-## Dependencies
+## Cross-Domain Communication
 
-**Cross-app model imports:**
-- `events.models.calendars.Calendar` — post routes and Ghost sync use calendars attached to pages
-- `market.models.market_place.MarketPlace` — post admin manages marketplaces on pages
-- `cart.models.page_config.PageConfig` — post admin manages per-page SumUp config
+All inter-app communication uses typed service contracts (no HTTP APIs):
 
-**Glue services:**
-- `glue.services.navigation.get_navigation_tree` — context processor builds site nav
-- `glue.services.relationships.attach_child / detach_child` — post admin attaches/detaches calendars and marketplaces to pages
+- `services.calendar.*` — calendar/entry queries via CalendarService protocol
+- `services.market.*` — marketplace queries via MarketService protocol
+- `services.cart.*` — cart summary via CartService protocol
+- `services.federation.*` — AP publishing via FederationService protocol
+- `shared.services.navigation` — site navigation tree
 
-**Internal APIs:**
-- Calls `GET /internal/cart/summary` — context processor for cart widget
-- Exposes `/internal/coop/*` — serves blog data to other apps
+## Domain Events
 
-**Domain events:**
 - `auth/routes.py` emits `user.logged_in` via `shared.events.emit_event`
+- Ghost sync emits `post.published` / `post.updated` for federation
