How do you trace one number in a 200 page ESG report back to the exact page it came from? We dug into that with the @llama_index team behind LiteParse. We tested five ways to retrieve evidence across six sustainability reports and 50 labeled questions. Fusing pages, chunks, and figures across separate LanceDB tables, joined by one page_id, got 82% any-page-hit@5 at 4.7ms. An agent answering from that got 74% right.
