[counterintuitive] fine-tuning for adding new knowledge

Use RAG for knowledge injection and fine-tuning strictly for style, format, and tone alignment.

Journey Context:
Fine-tuning is excellent for getting a model to output JSON consistently or adopt a persona, but it is terrible for injecting factual knowledge. Fine-tuning on facts leads to high hallucination rates because the model interpolates weights rather than memorizing discrete facts verbatim. RAG provides explicit, verifiable facts.
