test(architecture): apply the layer rules to repo packages

@@ -129,7 +129,7 @@ layers:
 |---|---|---|
 | API | `api` | REST controllers, request/response records, `ApiMapper`. Calls services, never repositories. |
 | Domain | `model`, `service`, `exception` | Plain Java models and business logic. Uses repositories, never API classes, entities or `EntityMapper`. |
-| Persistence | `persistence` | JPA entities, Spring Data repositories, `EntityMapper`. Entities never reach the API layer. |
+| Persistence | `persistence`, `repo` | JPA entities, Spring Data repositories, `EntityMapper`; `repo` holds `JdbcTemplate` queries. Entities never reach the API layer. |
 
 `profile` and `stats` only read data. They have no entities and use `JdbcTemplate` queries in a `repo` package.
 `version` has only an `api` package: `GET /api/version` answers the commit and build time of the running image.
