Three passes in, the document has been behaving. Then one question comes back with two receipts: clause 4 says thirty days, schedule 2 says sixty, both quoted, both about the same thing. Ask for a summary and you get one number and no mention of the other, because a summary is an exercise in making things agree. A contradiction is the one finding a long document cannot spin: both lines are already in it. 17 prompts for turning a document against itself and against the one it is meant to agree with: both lines quoted every time, the precedence clause found but never applied, NONE FOUND followed by what was compared, and the pairs handed to the person who can actually say which one holds.
