One question answered in full, the way a good reference page would: how we know, what is settled, what is contested.
2 credits·in-depth·about 2–4 min·one domain
Ask a question about history, science, art, music, literature, ideas or places. It gives the short answer, then the full answer under the sub-heads the subject calls for, sets out how we know with each kind of evidence graded, keeps what is settled apart from what is contested, corrects the common misconceptions, lists the terms, and closes with a reading list of real works and related questions.
The page a stranger reads: students, teachers, and anyone who wants the answer and the reasons in one place.
These are the headings the result renders, read from the same promise the form makes before you spend a credit. A section that depends on what the record holds is rendered when it can be and never promised here.
A settled matter and a contested one are never blended. A work on the reading list is a real book or paper with an author and a year, or it is not there; the page links only the sources it retrieved, never a reference it could not check.
A claim the scan could not source is marked as such rather than dressed up. How the grades work →
Its grounding, its vocabulary and its rules belong to this one domain.

The fastest way to judge the result is to pick a subject you know cold and read it against what you know. The scan names its credit cost before it runs.
