Rapid fire: how do RAG and fine-tuning relate, what do you do when content exceeds the context window, how do you keep conversation state, and how do you manage prompts?

RAG and fine-tuning fill different gaps: RAG supplies changing or citable facts, fine-tuning shapes format, style or a narrow skill. Over the window: retrieve only the relevant chunks, or summarise in a map-reduce pass. Conversation state: keep recent turns verbatim, summarise older ones, and store durable facts outside the prompt. Prompts: version them like code, with templates and a regression suite. Treat retrieved text as data, never instructions, to limit prompt injection.
