Knowledge — implementation evidence
Documents are extracted, chunked, contextualized and indexed. Search combines words and vectors by reciprocal rank. The turn reads a bounded set of passages from the same search service as the human search path. Tenant and folder scope apply both to searching and resolving matches.
Retrieval supplies evidence; it does not prove answer correctness. Current turn passages carry document name, ordinal, text and score. A durable evaluation workflow and source-faithfulness verdict are not established. No graph service is required.
