Updates assignment metadata, question responses or workflow status.

Send metadata, question updates and status changes separately. A status update may include question_code for validation. Completed assessments require a status-only reopen before question edits.

Use answer labels or codes and workflow/review labels from GET. Name changes affect all assignments; dates and contacts affect only the selected assignment. Create contacts separately. Unchanged metadata sends no additional notification; completion uses existing notifications. See the request schema for field-specific clearing rules. Quick Assessments use their own endpoint.
