 `order_id` on CalendarEntry and Ticket is a plain integer column — no FK constraint to the orders table. The cart app writes these values via glue services (`order_lifecycle.py`), not directly.
 
-## Cross-App Integration
+## Dependencies
 
-- **Cart checkout:** The cart app marks entries as "ordered" and sets `order_id` via `glue/services/order_lifecycle.py`.
-- **Payment confirmation:** Cart app marks entries as "provisional" via the same glue service.
-- **Login adoption:** Anonymous entries are adopted to the logged-in user via `glue/services/cart_adoption.py`.
-- **Internal API:** `/internal/events/` endpoints serve calendar data to other apps.
-- **Cart widget:** Context processor fetches cart summary via internal API.
+**Cross-app model imports:**
+- `blog.models.ghost_content.Post` — `app.py` context processor, calendar/market services for page hydration
+- `market.models.market_place.MarketPlace` — `app.py` context processor, marketplace views
+- `cart.models.page_config.PageConfig` — `bp/payments/routes.py` for per-page SumUp config
+
+**Glue services:**
+- `glue.services.relationships.attach_child / detach_child` — calendar and marketplace services manage page associations
+- `glue.services.navigation.get_navigation_tree` — context processor builds site nav
+
+**Internal APIs:**
+- Calls `GET /internal/cart/summary` — context processor for cart widget
+- Exposes `/internal/events/*` via `events_api.py` — serves calendar data to other apps
