In Week 9 you stored the six NorthPeak manuals in Chroma and retrieved chunks by similarity. In Week 8 you saw the model invent facts about M099. A retrieval chain joins the two: the retrieved chunks become the context, the system message forbids anything else, and your code checks that the model obeyed. This lesson gives the guard sentence, the shape of the chain, and five questions asked against the manuals.
