+### Roles and permissions
+- Roles are limited to `admin`, `technician`, and `employee`.
+- `admin` has full backend access.
+- `technician` only has aftersales/work-order module access.
+- `employee` has no backend login access and does not require a password.
+- Creating an employee through `/api/employees` creates employee master data and automatically generates one employee serial bound by `employeeId`.
+- `admin` / `technician` creation requires an initial password; `employee` creation must not require one.
