Can grounding be a mechanism instead of a request?

Asking a model to stay grounded in its sources is a request, and a request can be declined. This experiment moves the check out of the prompt and into the loop, where a failed check blocks the answer instead of annotating it. Open question: what the check should measure when the wording differs but the meaning holds.

Retrieval that cites what it used

A knowledge-base answer without sources is a claim, not a result. The experiment builds retrieval in .NET where every sentence in the answer can be traced back to a retrieved chunk. Still open: what happens when two chunks contradict each other and both look relevant.

An open question that has not found an experiment yet, and would not survive being forced into one.
