verdict.kechlab.com/v1/extract

An agent has a text (email, invoice, listing, web page, contract) and the list of fields it wants out of it: it gets JSON in the requested shape, one value and one quote per field, or null when the text does not say. Code then checks that every quote is really in the text and flags those that are no
