activity property
Activity is the one line saying what the run is doing right now ("running the reaper's tests"), up to 120 characters, in the model's words. Empty when nothing has estimated it yet.
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? activity;
