Read a document with AI and match it to its line

The workspace's own language model reads a stored PDF of a signed option grant or stock purchase agreement: what it is, the holder, the number of options or shares, the price per share and the date. Each value comes with the exact words it came from and their page; a value whose words aren't in the file is dropped, and the kind, numbers and date are taken from those words, never from the model. A value its words don't settle comes back as null, for a person to fill in. The holder's line of that kind is proposed, preferring one without its agreement, with what the document says differently from it. Nothing is saved: attach the document with captable.attach. Needs an owner's language model key.
