[counterintuitive] more context window better performance

Optimize context density. Prune irrelevant context aggressively. Use structured formats and keep only strictly necessary information to avoid 'lost in the middle' effects and increased latency.

Journey Context:
LLMs suffer from attention dilution \(Lost in the Middle\). Cramming the context window increases latency \(quadratically for attention in base models, or practically via KV cache bottlenecks\) and cost, while decreasing instruction-following reliability if the relevant signal is buried in noise.
