## Overview

DocMind appears to be a Spring backend for document ingestion and retrieval-augmented chat. The tree identifies API controllers, ingestion/parsing and metadata services, a RAG service, and a metadata repository. No README or source excerpts were provided, so internal call wiring and external AI or vector-store integrations cannot be verified; the graph shows only the API boundary and repository/store relationship implied by their names.
