"""
T-UC3: Knowledge Chatbot.

The chatbot feature instance was removed from the InvestorDemo on
2026-04-20 (see changelog) — neither HappyLife nor Alpina bootstrap a
chatbot today; the actual RAG demo runs via workspace. We still verify
the knowledge-base demo files are present and that the bootstrap does
NOT (re)create chatbot instances in either mandate.
