The value needs a supplied definition

Two values both fit the field's NAME; only the definition in the schema decides which counts. Illustrative only (not the fixture): an invoice shows Subtotal $1,000 and Total $1,180, the field is `amount`, and its definition says amount excludes tax — so $1,000 is right, though $1,180 is the more prominent number. This is the configuration half of the pair whose training half is the labeled-example scenario: the same kind of private rule, delivered through a different channel.
