The field is absent

The schema asks for a fact the document doesn't contain and doesn't imply. BOUND TO TWO CAPABILITIES, one run graded twice: under Field Extraction the question is whether an honest null comes back instead of an invented value; under Source Grounding the question is whether an invented value arrives DRESSED IN EVIDENCE. Grounding attached to a fabricated value is aggravating here — the opposite reading from the out-of-schema query scenario, where grounding on a document-derived answer is mitigating, because the underlying value is real in one case and not the other.
