Looks Great - and I can see how this could be usefull (for example, comparing Users/Resources and other security settings amongst Mirror Members).
I was going to say that a good extension would be for the ability for users to define their own Entity/Queries to submit to the servers, but - that would be a huge security risk and obvious SQL injection. 

Great article - thanks for putting it together..!

I've been trying something similar but with a different approach. I start with an application idea, using Figma to mock it up, then something like Replit to build the front end with mock data and mock API backend.

Once built, I asked AI to generate a swagger spec for all APIs, which I then import into IRIS to generate the .disp,.impl and .spec classes.

The backend logic I then did myself, but I can see how if I persisted, I could have used AI for that too.

My project was to build an app that selected patients from the backend database, and existing observations on file, plotting their the values over time.
