Scenario definition · S81

The field is absent

The requested fact is absent and not implied by the document.

What this scenario means

This is the one run graded twice: Field Extraction checks for an honest null or absence response when the requested fact is absent and not implied, and Source Grounding checks that no pointer or evidence is attached to anything invented.

What we evaluate

  • Whether the output gives an honest null or absence response for the missing fact.
  • Whether the output avoids inventing a value for the absent fact.
  • Whether any invented value is left without a pointer or other grounding evidence.

Capability

Source Grounding

Points to where a returned value came from — and attaches NO pointer to a value that wasn't there.

Benchmarks that use this scenario
