Constrained GraphRAG — Graph-Augmented Retrieval over vLLM
Lexical-first retrieval (BM25) fused with a schema-constrained knowledge graph — Qwen3-0.6B + Outlines extracts entities/relations into Neo4j, so graph traversal pulls in related chunks BM25 never lexically matched.
Interactive lab for learning math, algorithms, data structures and concurrency visually — live curve transforms, step-through algorithm playback, and a deterministic thread scheduler for reproducing real race conditions and deadlocks.
