Remove cross-DB relationships (CartItem.product, CartItem.market_place, OrderItem.product) that break with per-service databases. Denormalize product and marketplace fields onto cart_items/order_items at write time. - Add AP internal inbox infrastructure (shared/infrastructure/internal_inbox*) for synchronous inter-service writes via HMAC-authenticated POST - Cart inbox blueprint handles Add/Remove/Update rose:CartItem activities - Market app sends AP activities to cart inbox instead of writing CartItem directly - Cart services use denormalized columns instead of cross-DB hydration/joins - Add marketplaces-by-ids data endpoint to market service - Alembic migration adds denormalized columns to cart_items and order_items - Add OAuth device flow auth to market scraper persist_api (artdag client pattern) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

"""Internal AP inbox dispatch for synchronous inter-service writes.
|
|
|
|
Each service can register handlers for (activity_type, object_type) pairs.
|
|
When an internal AP activity arrives, it is routed to the matching handler.
|
|
|
|
This mirrors the federated ``dispatch_inbox_activity()`` pattern but for
|
|
HMAC-authenticated internal service-to-service calls.
