[counterintuitive] more context window better performance

Curate context aggressively; place critical information at the very beginning or end of the prompt; use RAG to fetch only highly relevant chunks rather than dumping entire documents into the context window.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon. When relevant information is buried in a sea of irrelevant context, retrieval accuracy drops significantly below even zero-shot baselines. More context increases noise, latency, cost, and degrades instruction following due to attention dilution.
