 - Lifespan handler initializes a dev httpx.AsyncClient using settings.frontend_dev_url and stores it on app.state; it is closed on shutdown
 - Removed legacy inlined endpoints/helpers from main.py after extraction
 - Kept product creation endpoint in main pending Phase 4 move
+- Adjusted route signatures to use required Request and proper parameter ordering to satisfy FastAPI and Pydantic
+- Removed duplicated placeholder endpoints from api/shopping.py that were left from scaffolding
+- Added temporary back-compat shims in main.py (get_duplicates, validate_meal) forwarding to api.meals to keep tests passing; plan to remove in Phase 4 when tests are updated to import from feature modules

-- [ ] Define cookie-based security scheme in OpenAPI and apply to secured routes
+- [x] Add Location header on create endpoints (recipes, meals, persons, products)
