Grounding, from Week 8, puts the facts in the prompt. The search built this week finds those facts in the NorthPeak manuals. Retrieval-augmented generation, or RAG, connects the two steps and adds a rule: answer only from the retrieved chunks and cite the source file. Not every question is a similarity question, though. Which incidents happened on M014 is a walk along relations. This lesson covers the RAG loop, the checks it needs, and knowledge-graph retrieval on edges.csv.
Week 8 ended with grounding: put the facts in the prompt. Week 9 built the search that finds the facts. Retrieval-augmented generation, or RAG, connects the two. Four steps, every time a question arrives.
