The claim appears in the source material but arrives without a source marker of its own, so there is nothing to grade. Some analyses call this "untestable from the record". It is reported as-is, with no claim made about how well supported it is.
The definition the product enforces, read from the same code the methodology page renders.
A claim that appears in the material with no source marker of its own. The page reports it as it arrived and makes no claim about its support. If a stated row matters, it is a candidate for a follow-up question, not a fact to carry.
The grade every claim on a research page carries: how it is known, not how confident it sounds. Assigned by the same rules on every scan; the rollup numbers are computed from the graded rows.
Every grade here is assigned by the same rules on every scan, and the methodology page renders those rules from the code that enforces them.
