session property
Session is the id of the agent session this story IS — the same value a produced commit carries in its Hanzo-Session: trailer, which is what ties the repository's history to this page.
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? session;
