published property
Published is the author's decision to let anyone read this session's story at the public build route. It only ever widens READ access to a session that already exists and grants nothing else; false, an unpublished session is invisible there no matter who asks. It cannot be true without a Project, because that route is keyed on (org, project).
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
bool? published;
