Background the model already knew rather than something it read during this run. It is kept because it is usually load-bearing context, and it is labelled because nothing about the run confirms it. Where the schema requires one, a ready-made search rides along so you can check it in one tap.
The definition the product enforces, read from the same code the methodology page renders.
Background the model already held rather than something it fetched this run. It is kept because it is usually the context the rest stands on, and labelled so you know nothing in the run confirmed it. Where the schema requires it, a ready-made search sits beside the row.
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.
