Builds a hierarchical table-of-contents index over long documents that mirrors their actual section structure.

Reasoning Retrieval

Navigates the document tree by reasoning about which sections answer a query, with no embedding database required.

Citation Tracing

Returns the exact node and page a retrieved passage came from so answers stay traceable to the source document.
