+- Replace `{ingredient_id}` with actual parent ingredient UUID
+- Replace `{composition_id}` with actual composition UUID
+- Replace `CHILD_INGREDIENT_UUID_1` and `CHILD_INGREDIENT_UUID_2` with actual child ingredient UUIDs
+- Parent ingredient must have `is_semi_finished: true`
+- All responses now include the updated parent ingredient with recalculated cost
