1. *The safety loop is part of the architecture, not an add-on.* The naive self-improvement loop (feedback -> change -> merge) is a footgun; what makes it survivable is the harness around it: regression gates, merge gates, evolution logs, and a constitution the agent cannot modify. I'd love to see the course treat "safe recursion" as a first-class topic with the same rigor as the learning algorithm.
2. *Evaluation of self-improvement is genuinely hard.* How do you measure "the agent got better" when the agent wrote the tests too? We use a mix of external signals (user feedback, merge rates) and pinned golden tests, but it's still the weakest part of our setup.
3. *The human feedback channel matters more than the algorithm.* Our most valuable improvements came from explicit user frustration signals, not from the agent self-discovering problems. Cheap "that was bad" input beats clever self-critique.
