[counterintuitive] Fine-tuning LLMs to inject new factual knowledge

Use RAG for knowledge updates; use fine-tuning only for style, format, or behavioral alignment.

Journey Context:
Developers treat fine-tuning like a database update. However, LLMs struggle to memorize new facts via fine-tuning without high hallucination rates, as they interpolate weights rather than store discrete facts. RAG provides explicit, verifiable facts at inference time.
