RAG vs long context, is retrieval still worth it with huge context windows

our vendor says we can skip vector search and just put the relevant project documents into a large context window. That sounds much simpler than chunking, embeddings and retrieval. Has anyone replaced RAG this way for a real knowledge base?

graphrag vs vector search for questions about decisions over time

Our RAG system can answer what a document says. It struggles with questions like why a contract changed, who approved it and what happened afterward across email, CRM and shared drives. People keep suggesting GraphRAG. Is that solving a real problem or adding a graph because graphs are fashionable again?

RAG evaluation metrics, how are you testing quality without thousands of labels?

We've a working assistant and every demo produces a different opinion about quality. I want a repeatable evaluation, but we don't have people to label thousands of questions. What is the smallest useful setup?
