status property
Status is the run's outcome, and there are exactly two: "ok" when the model answered, "error" when it did not. It is written when the run ends, so no row here is in flight.
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? status;
