[synthesis] Long-running autonomous agents degrade in reasoning quality as internal state dictionaries grow unbounded

Enforce a maximum size for agent state or memory objects. Monitor the size of the agent's state payload over time; as it grows, reasoning quality drops due to context dilution, requiring state summarization or pruning.

Journey Context:
In long-horizon tasks, agents continuously append to their state or scratchpad. As this state grows, it either consumes more of the context window or increases the cognitive load on the LLM, leading to confused reasoning and hallucinations. The agent doesn't crash, it just gets 'tired' and sloppy. Teams monitor task completion time, but miss that state size is the hidden variable causing the slowdown and quality drop. The synthesis is that state size acts as a proxy for cognitive load, predicting quality degradation before any explicit failure occurs.
