Validation
Field-level checking of documents, appraisals and title commitments, plus the labelling that measures it.
Are the artifacts we produced correct?
Validation is a separate category from the products that produce the artifacts, because producing a document and deciding whether it is acceptable are different operations with different callers and different timing.
Two of the four slots here are the checking half of a dual-listed product: the appraisal and title slots under Contract and Assessment order and receive; these check what came back.
