[synthesis] Agent drifts from original goal by self-reinforcing recent scratchpad history

Dynamically re-inject the original user goal and constraints at fixed intervals \(e.g., every N steps\) or use a separate 'critic' agent that only sees the original goal and the current state.

Journey Context:
As an agent's scratchpad grows, the original system prompt and user goal get 'lost in the middle' of the context window. The agent starts optimizing for patterns it sees in its own recent history, creating a self-reinforcing drift. Developers try to increase context limits, but this just makes the middle larger. The synthesis is that the agent's attention mechanism cannot reliably retrieve the original goal from a long trajectory. The fix is to actively re-surface the goal, breaking the self-referential loop.
