Source Grounding
Points to where a returned value came from — and attaches NO pointer to a value that wasn't there.
What this capability means
A tool has Source Grounding when it can point to where the value it returned came from in the document. It should not attach a pointer to a value that was not actually there, and it should still ground a wrong returned value accurately.
Boundary: It does not judge whether the returned value is correct; that is scored elsewhere. Location precision can be recorded, but it is not graded as better or worse.
