  "description": "Additive referential view, separate from source records and candidate leads. ref-N resolves through source_refs to exact public record items and physical-page evidence. Headlines dereference typed quantities; they do not aggregate repeated requests. Events retain stages; dates describe these sources, not present legal status. annotations retain relocated cross-document reading commentary. The original research proposal remains unchanged in the registered extraction. No global entity index is needed."
