I feel mostly confused by the way that things are being framed. ELK is about the human asking for various poly-sized fragments and the model reporting what those actually were instead of inventing something else. The model should accurately report all poly-sized fragments the human knows how to ask for.
I think this is what I was missing. I was incorrectly thinking of the system as generating poly-sized fragments.
Thanks for taking the time to explain this!
