   - Replace internal usages with `user_id`/`MemberRef` where outward, and update repository DDL to stop referencing `Person`.
   - Remove `api.deps.cookie_person` once no tests or code depend on it.
+  - 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.
