The parser looks at the doc profile it just got from the parsing brick: doc_type: insurance_policy n_pages: 47 toc_df names General Information, Coverages, Exclusions, Endorsements. No section called Premium. Naive top-k embeds “premium” and scans the whole document. It returns exclusion…

The model was handed the wrong pages and did its job on them. Retrieval decides what the model can invent, because it decides…
