+# Reinitialize User with Default Props
+
+When stock props or avatars are updated in the database, existing users may need to be reinitialized to receive the new defaults.
+
+## Steps
+
+1. Find the user's ID:
+
+```sql
+SELECT id, username FROM auth.users WHERE username = 'TARGET_USERNAME';
+```
+
+2. Clear existing data and reinitialize:
+
+```sql
+BEGIN;
+
+-- Clear existing props and avatars for the user
+DELETE FROM props.active_avatars WHERE user_id = 'USER_UUID';
+DELETE FROM props.avatars WHERE user_id = 'USER_UUID';
+DELETE FROM props.inventory WHERE user_id = 'USER_UUID';
+
+-- Reinitialize with current server props
+SELECT auth.initialize_new_user('USER_UUID');
+
+COMMIT;
+```
+
+3. Verify the results:
+
+```sql
+SELECT COUNT(*) as inventory_count FROM props.inventory WHERE user_id = 'USER_UUID';
+SELECT id, name, slot_number FROM props.avatars WHERE user_id = 'USER_UUID';
+```
+
+## Example: Reinitialize ranosh
+
+```bash
+psql -d chattyness <<'EOF'
+BEGIN;
+
+DELETE FROM props.active_avatars WHERE user_id = '57a12201-ea0f-4545-9ccc-c4e67ea7e2c4';
+DELETE FROM props.avatars WHERE user_id = '57a12201-ea0f-4545-9ccc-c4e67ea7e2c4';
+DELETE FROM props.inventory WHERE user_id = '57a12201-ea0f-4545-9ccc-c4e67ea7e2c4';
+
+SELECT auth.initialize_new_user('57a12201-ea0f-4545-9ccc-c4e67ea7e2c4');
+
+COMMIT;
+EOF
+```
+
+## What `initialize_new_user` Does
+
+The `auth.initialize_new_user()` function:
+
+1. Inserts all face-tagged server props into the user's inventory
+2. Creates a default avatar (slot 0) with:
+   - Face prop in the skin layer (position 4, center)
+   - All emotion props mapped to their respective emotion slots
