Description	A multi-model database supporting graphs, key-value pairs, and documents in a unified JSON-based data model. Offers both an in-memory storage engine and a RocksDB-based engine for larger datasets.	A source-available property graph engine written in Rust that combines typed edges, vector search, and bitemporal facts for retrieval-augmented generation workloads. Queried through a composable operator API over CLI, HTTP, and MCP rather than a graph query language.
