Why this doesn’t make things up
It never does the mathematics
It finds a passage someone wrote and checked, and hands it over. It does not compute, rewrite or paraphrase — so there is nothing for it to get wrong.
Everything is checked first
147 solved questions, each verified against the official answer key and, where the mathematics allows, against a symbolic algebra system.
It admits what it doesn’t know
Where nothing matches, it says so rather than guessing. Those questions become the list of what gets written next.
