Engineering notes

Things I have had to explain more than three times

Long-form technical writing on the decisions that actually move a project: what crawlers see, why a RAG assistant must be able to refuse, how a performance budget survives contact with a sprint, and how to pick a stack honestly.

    The most important feature of a RAG chatbot is the refusal

    Everyone measures retrieval hit rate. Almost nobody tests whether the assistant correctly says "I don't know" — the failure that actually costs a customer.
