status property
Status is the board column: backlog, todo, in_progress, done or canceled, and nothing else. On a forge row it is read off a LABEL, so relabelling in the forge web UI moves the card here and vice versa — and a CLOSED forge issue reads done whatever its labels say. Never empty: "backlog" when nothing names a column.
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;
