[frontier] Agent quality degrades significantly after 30\+ turns in same context window

Implement session segmentation: break long tasks into sub-sessions with fresh context windows, transferring only essential state \(current goal, key decisions, active constraints\) between them. Do not transfer full conversation history.

Journey Context:
Rather than trying to fix drift within a single long context, leading teams in 2025-2026 are avoiding it entirely by segmenting sessions. The key insight is that most 'state' from earlier turns is irrelevant to the current task — only the current goal, relevant context, and key constraints need to transfer. This gives you a fresh context window with full instruction fidelity. The tradeoff is engineering complexity in state management and potential loss of subtle context, but the consistency improvement outweighs these costs for production systems. This is becoming the default architecture for reliable agents.
