Open Source Project of the Day (#152): SAG — Multi-Hop RAG Retrieval via SQL JOINs Instead of PageRank

Zleap-AI's Structured Agentic Graph RAG framework extracts each document chunk into one semantic event and multiple entities, then uses SQL JOINs at query time for multi-hop expansion — no global graph pre-built, no PageRank decay. MuSiQue Recall@5: HippoRAG 2's 65.1% → SAG's 80.0%. MIT license with MCP integration.
