-## GraphRAG — Lightweight Graph Capabilities
+## GraphRAG — Graph Traversal (Phase 2 Complete)
 
-Planned graph traversal capabilities enabling hybrid **Vector + Graph** queries for AI Agents, code analysis, and knowledge graphs.
+GraphRAG traversal capabilities are implemented with BFS/DFS/Bidirectional/Dijkstra over ROWREF columns and `GRAPH_TRAVERSE()` SQL evaluation. Hybrid graph+vector optimization is available as ordering hints only.
+
+### Key Features (Current + Planned)
+
+- **ROWREF Column Type:** Implemented
+- **BFS/DFS/Bidirectional/Dijkstra Traversal:** Implemented
+- **GRAPH_TRAVERSE() SQL Function:** Implemented
+- **Hybrid Vector + Graph Optimization:** Prototype (ordering hints)
+- **A***: Planned
+- **Multi-hop Index Selection:** Planned
+
+**Status:** ✅ Phase 2 complete (Phase 3 prototype)

-- **BFS/DFS Traversal Engine:** 1M nodes in <100ms
-- **GRAPH_TRAVERSE() SQL Function:** Graph queries in standard SQL
-- **Hybrid Vector + Graph Queries:** Combine HNSW similarity with structural constraints
-- **Status:** 📋 Planned for v1.4.0 (Q3 2026)
