Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: The requirement and the question of current value or history
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: "Record the customer's address." Acceptable: "Record the customer's address as it was on a payment's value date, so a past statement can be reproduced with the address in force at the time."
Also known as: Time not stated (data requirement)
