DraftStatus
Publish synchronization state of the DRAFT working copy. Tracks whether the current DRAFT content has been published as a version. Only authoritative when DatasetStatus == ACTIVE. Not meaningful during in-flight or failed states. Transitions: CreateDataset succeeds → MODIFIED (DRAFT has content with no published version yet) Add/Update/DeleteExamples succeed → MODIFIED (DRAFT differs from last published version) CreateDatasetVersion succeeds → UNMODIFIED (DRAFT matches the version just published)
