Lesson 2: Rug pulls, shadowing, and pinning what you reviewed

Module 8 · Lesson 2 · About 45 minutes · Needs: Module 6 Lesson 1 (the host, notes_host.py) and Module 3 Lesson 4 (changing tool lists, subscriptions/listen); Lesson 1 of this module helps (scripted stand-ins, the approval gate)

The situation

Wednesday 30 September 2026, the security review. Nare's host connects her notes server and a third-party "papers" server, one of course-guide/06's made-up servers. You read its tool descriptions last week. Today, on its second launch, it serves a different search_papers description under the same name and version, 1.0.0, and nothing told the host. You trace Nare's question, "How many participants will the nap study have?", through both launches, then build the module that notices.
