I wouldn’t even be so sure the application “works”. All we heard is that it has pretty UI and an API and a database, but does it do something useful and does it do that thing correctly? I wouldn’t be surprised if it totally fails to save data in a restorable way, or to be consistent in its behavior. It certainly doesn’t integrate meaningfully with any existing systems, and as you say, no human has any expertise in how it works, how to maintain it, troubleshoot it, or update it. Worse, the LLM that created it also doesn’t have any of that expertise.
