Decision 39 couples teeth and jobs on a lab-dependent type, so unticking the merged row and then the type row applies a detail with no teeth at all. master kept them, because the rows were separate. Approved as an accepted consequence rather than patched, since applying teeth the clinician just unticked would break the sheet-is-a-contract rule.
