shape property
Shape is the model's identity, as <family>:<digest>: the KIND of model, and that family's own digest over the inventory in order and the detector's geometry parameters. It is what an auditor pins an alert to, because learned state is only meaningful against the space that produced it — and the family leads it because two families' masses are not fitted differently, they are different kinds of number.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? shape;
