-## [Backend] `get_password_hash` lives in `setup_service` but is used by `auth_service`
-
-**Where found**
-
-- `backend/app/services/auth_service.py:27` — imports `get_password_hash` from `setup_service`
-
-**Why this is needed**
-
-`auth_service.py` handles all authentication concerns and is the natural home for password hash retrieval. Having it import from `setup_service` creates incorrect semantic dependency and unnecessary coupling.
-
-**Goal**
-
-Move `get_password_hash` to `auth_service.py` where it belongs, or to a shared `app/utils/crypto.py` module.
-
-**What to do**
-
-1. Move the `get_password_hash` function body from `app/services/setup_service.py` to `app/services/auth_service.py`
-2. Update the import in `auth_service.py` to use the local function
-3. Search all of `backend/app/` for usages and update imports
-4. Remove the function from `setup_service.py`
-
-**Possible traps and issues**
-
-- Search thoroughly for all usages before removing — may be imported in tests, other services, setup router
-- If used during initial setup flow, update that usage to import from `auth_service` instead
-
-**Docs changes needed**
-
-- No documentation changes required — internal code reorganization
-
-**Doc references**
