### Verifications

* 🔧 **Make `id-valid-dates-detection` not applicable to limited-term or temporary IDs**: For limited-term or temporary IDs, the `id-valid-dates-detection` check now returns a new "Not applicable" reason: `unknown-date-rules`. The rules used in this check do not apply to these IDs. Before, this check would usually return a failed result for these IDs.

### Cases

* 🔧 **Prevent duplicate Case objects**: A new check ensures each object can only be [attached to a Case](/cases#adding-data-to-a-case) once.
