# LeanSearch v2 — Mathlib v4.28.0-rc1 cuVS index

Pre-built cuVS CAGRA index over every Mathlib v4.28.0-rc1 declaration, encoded with [Qwen3-Embedding-8B](https://huggingface.co/Qwen/Qwen3-Embedding-8B); drops directly into the LeanSearch v2 serving pipeline (`cuvs_index.bin` + `metadata.pkl` + `texts.pkl`).
