The material a scan actually read during its run and the sources it cites.
The product’s working definition.
What the scan actually read: the reporting, the filings, the datasets and the documents it fetched during the run, plus the sources it cites. When a page says "the record cannot establish" something, it means this material, not the world.
The handful of nouns the pages use for the things the product makes and keeps.
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.
