Explainer

Explainer is a word meaningan article that lays out and links the graph's claims into readable prose — an entry point that makes the reasoning legible for a newcomer, informing and explaining rather than advocating or calling to act.

It is not challenged like a single reasoning step: an explainer rests on the claims it cites, so a disagreement is taken up with those; the article itself can still be discussed for its clarity, balance or what it leaves out.
