pending property
Pending is how many of this tenant's assertions the DERIVED columnar copy is not known to hold yet. Every count above is folded from the record, so they are right regardless — but a materialiser that joins in the warehouse while this is non-zero is joining against an incomplete answer key, and a missing fraud label is indistinguishable from an honest customer. It is reported at the training gate because that is where somebody is deciding whether the ground truth is good enough to fit on. Counted under a cap, so it saturates rather than costing a full scan on every read.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
