What should Mateo test first? Rerank a larger candidate set and pass only the strongest final chunks to the answer step Rewrite the answer prompt so the model infers the missing source from nearby chunks Lower top_k to 5 so retrieval is faster and the generator sees less noise Change the embedding model immediately without measuring whether candidates are…
