## Overview

This repository currently documents a research framework, not an implemented codebase: the tree contains a README and assets only, and the README says code, pretrained models, and FKG-50K are forthcoming. The documented workflow takes an image through forensic trace extraction and region analysis, constructs a grounded Forensic Knowledge Graph (FKG), then uses Iterative Context Refinement (ICR) with a VLM to produce a justified report. The graph reflects those documented stages and capabilities; paths are null because no implementation paths are present.
