Most document AI is built to answer one question: where is this number on the page?

But the number people need often isn't on the page. It has to be calculated from the numbers that are.

Higher-Order Extraction from Unsiloed does that calculation.
It calculates numbers a document never prints by generating deterministic code from page values.

e.g. you ask for the final figure, it reads the raw values from the document, writes code that combines them, and runs that code to get the answer. Every result traces back to the page.

There's a second check. If the document happens to print the answer somewhere, the system compares it with its own result. If they match, confidence goes up. If they don't, confidence drops to zero.
