We talk a little bit about this in the paper, but just a bit. And it is an important question. Real entities change! We’re not just trying to create a representation of now, but a historical record of how we got here. The two ideas we played with that didn’t make it in the paper were 1) explicitly tell the NERD system to keep a timeline for each entity that tracks “core state” changes. 2) Let the NERD-agents also access the full change log of the NERD documents, so that they could see the history of the document. Possibly like a git history. For the paper we left these out because they were both too complicating.
