[synthesis] Agent loses nuance in long sessions without throwing context limit errors

Instrument the inputs to the final decision-making step to detect the loss of specific entities \(e.g., proper nouns, IDs\). Track entity density in the context window. If entity density drops sharply while context length remains high, the summarization step is flattening critical state.

Journey Context:
When context windows approach limits, systems implement rolling summarization. The silent failure is that summarization removes the exact specific details \(IDs, exact names, edge-case constraints\) the agent needs to act accurately, replacing them with generic summaries. The agent continues executing, but operates on generic rather than specific state, leading to subtly wrong actions that don't throw hard exceptions.
