In Pega/PRPC, a concrete class (one that can have actual work object instances) must belong to a class group so the platform knows which database table to store its instances in alongside other classes sharing the same key format. There's no naming convention where a trailing hyphen forces a class to be abstract, and a class group itself doesn't require a key — it's the concrete class's need for storage that drives the class-group requirement.
