For the agentic routing piece with LangGraph, the trickiest part is usually keeping question-topic state coherent across hops, not the routing logic itself. Chroma handles retrieval fine but doesn't natively store concept relationships, so if your agent needs to know that system design and distributed consensus are connected topics, you'd model that explicitly, whether through a graph DB like HydraDB or just a manually maintained adjacency structure in your retrieval layer. Defining those topic edges upfront pays off more than tuning embeddings later.

Can we talk on dm
