 But beyond throwaway prototypes, it's plausible to have sections of the application that have never been read by humans. I can give several examples from my geometric art application. 
 
-- AlgorithmBuilder typings
-- Mathsy parts of node implementations
-- The entire graph view (though this falls more into the 'throwaway prototype' category of unread code)
 
-But the key thing to highlight here is that _how these things are used_ is understood.

 We might not have read the implementation - but we've read and understood the tests.
