+# ruvector-cluster-rag
+
+Experimental hierarchical retrieval over a two-level tree of leaf vectors and
+k-means cluster summaries. It includes exhaustive, IVF-style, and
+coherence-weighted search variants.
+
+```bash
+cargo test -p ruvector-cluster-rag
+cargo run --release -p ruvector-cluster-rag --bin benchmark
+```
+
+Clustered variants are approximate. Tune the cluster count, probe count, and
+coherence weight against workload-specific recall and latency targets.
