Practice, exams, and production annotation
Practice builds correct-answer progress. An exam earns qualification for one type. Production tasks are handled in the Annotation Workspace. Their answers and statuses are stored separately.
Task states
Draft means saved but not submitted. Submitted means sent to the next stage or review. Returned means revise using feedback. Approved means complete. Saves and state changes create versions or log entries.
