facts property
Facts is how many assertions the window holds; Events is how many distinct judged events they cover. The two differ by exactly the corroboration and the conflict in the plane.
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
int? facts;
