   ETF Agent Maps the RAG Evidence-Delivery Chain

   An ETF Agent engineering report organizes RAG into four interacting chains: knowledge construction, online retrieval, evidence consumption and delivery, and evaluation and governance. In the checked private knowledge path, lexical retrieval can use BM25 when the PostgreSQL pg_search extension, a BM25 index, and configuration are available; otherwise it uses PostgreSQL full-text search. Code support alone does not show that any particular query used BM25. The public Open ETF Agent repository offers a smaller teaching implementation with restricted lexical retrieval, original-page readback, and source-linked reporting on synthetic documents, rather than the full private architecture. An RQ-08 evaluation fixed three source versions to one candidate set, compared the ranking of 306 real indexed chunks, and observed actual Knowledge calls. However, the chunks lacked complete manual relevance labels, and some reads confirmed only that a location was found. The results therefore do not establish improved real Recall or end-to-end financial-answer accuracy.
