Seems, at least at a cursory glance, to produce decent output.
Can I use a star-tree index with upserts?
I was pleasantly surprised by the answer:

Briefly: "No, you cannot use a star-tree index with upserts in Apache Pinot. This is a built-in restriction that is explicitly enforced in the system."
Why This Restriction Exists
When upserts are enabled for a table in Pinot, the system explicitly checks and prevents the use of star-tree indexes. This validation happens during table configuration validation.
The code in TableConfigUtils.java explicitly enforces this restriction:

At cursory glance, I did not detect a hallucination. The answer was true (AFAIK), clear, and objective. I also see that you can peek into other resources to get some additional contextual information.
Very impressive work.
I can see a lot of merit in custom building though especially with making it easier to dump it into `llms.txt` or exposing a search for AI. Hoping that's where DeepWiki is headed :)
