[counterintuitive] fine-tuning for new factual knowledge

Use RAG for adding new factual knowledge; use fine-tuning only for altering tone, format, or teaching specific behavioral heuristics \(style transfer\).

Journey Context:
Developers treat fine-tuning like training a human who reads a textbook. In reality, fine-tuning is notoriously bad at injecting new factual knowledge—it causes the model to hallucinate or overfit to the specific phrasing of the training data. Fine-tuning changes the prior \(how it answers\), not the knowledge base \(what it knows\).
