commit property
Commit is the full sha this turn produced, empty when the turn changed nothing. It is ECHOED from the transcript, and the authority is the commit itself: it carries the Hanzo-Session:/Hanzo-Turn: trailer, or a note under refs/notes/hanzo-provenance saying the same, so the claim is checkable at source with the command in verify.
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? commit;
