This came from what you typed into the scan — a premise, a figure, a piece of context. The analysis built on it without checking it, because you asserted it. If it turns out to be wrong, everything downstream of it is worth re-reading.
The definition the product enforces, read from the same code the methodology page renders.
You said it, so the scan built on it. The page marks it so that if the premise turns out wrong you know which rows sit downstream of it. A scenario and a council read are made almost entirely of your input, by design.
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.
