 Remaining work (prioritized cleanup to final state):
-1. Remove the `persons/` package and all code references across domains (recipes, meals, shopping). Replace `Person` with `users`/HouseholdMember everywhere:
+1. Remove any remaining references to legacy `Person` semantics in comments or deep internals; ensure all code paths exclusively use Users and HouseholdMember.
-  - Code hotspots today: `recipes/models.py` (imports Person), `recipes/repository.py` (FKs, hide_recipe signature), `meals/models.py` (participants as List[Person]), `api/shopping_models.py` and `shopping/models.py` (ShoppingList.purchased_by typed as Person), and `shopping/repository.py` (FKs to Person).
+  - Verify repositories and models have no lingering Person FKs or types; outward schemas consistently use `MemberRef`.
-  - Replace internal usages with `user_id`/`MemberRef` where outward, and update repository DDL to stop referencing `Person`.
-  - Removed `api.deps.cookie_person` and `cookie_person_optional`; v1 tests referencing them remain skipped and will be deleted or ported.
   - Ensure no API module performs direct SQL; all persistence must flow through repositories (enforced during cleanup).
 2. Recipes outward schema: DONE for `createdById`/`createdBy` and `hiddenById`/`hiddenBy` (MemberRef on delete). If/when we expose hide actor on other flows, keep MemberRef.
 3. Shopping outward DTOs: DONE — `ShoppingListOut.purchasedBy` is a MemberRef; mapping added. Ensure clients shift to `displayName`.
-4. Delete or port legacy v1 test modules that are currently skipped (`tests/test_main.py`, `tests/test_v1.py`). Either migrate assertions to v2 routes or remove them so the full test run has no skips. Then remove the last vestiges of v1-only helpers.

   - Add composite indices like `(household_id, id)` where pagination benefits (e.g., Recipe, Meal, ShoppingListItem).
   - Add explicit FK constraints from tenant tables to `Household(id)` where safe.
