🧠 LiteRAG — Zero-LLM GraphRAG Framework

Research paper submitted to EMNLP 2026 — I architected the framework and authored 100% of the code.

A next-gen GraphRAG system that replaces expensive LLM-driven retrieval with pure mathematical graph navigation, achieving O(1) constant-time latency at any dataset scale.
