If your mental model of RAG is "chunk → embed → search → LLM," you're missing about 80% of what actually makes a RAG system production-ready.

[ ] Can you update a single document without a full re-index?
[ ] Do you have a deletion path (not just an addition path)?
[ ] Are you deduplicating before you embed?
