Humans on the Loop: How-to Actually Monitor and Govern Production AI

"Don't trust AI" has mostly meant, to date, "be sure to keep a human in the loop (HITL) for any serious decisions". However, at the rate at which AI models can now generate output, HITL has become completely untenable; "in the loop" has become "rubber-stamp/agree as quickly as humanly possible". In this tutorial, I will introduce the practical HITL alternative: "humans on the loop". With this alternative in mind, we will discuss - then build! - the infrastructure to detect and alert on actions that actually need a human decision, while keeping a full audit trail for later review. For a concrete scenario, we will use a clinical AI coding agent, but the architecture applies anywhere that an AI model might be making impactful decisions faster than a human can keep up with it. We'll work in Python and Streamlit to implement a Risk Scorer, wire the scorer into a live decision feed, fed by an AI model, and build a human review queue backed by a full audit log. You will leave with a working, runnable codebase that you can adapt to your own systems.
