[synthesis] Agent locks in flawed approach after context window summarization

When summarizing context, explicitly separate established facts from attempted approaches and their outcomes. Maintain a separate dead ends scratchpad that survives summarization to prevent the agent from assuming the success of failed paths.

Journey Context:
As context windows fill, agents use summarization to compress history. If an agent spent 8 steps pursuing a flawed approach, the summarizer compresses this into Configured X using Y. The nuance that Y was a failed workaround is lost. The LLMs attention mechanism treats the compressed summary as ground truth, creating a sunk cost trap where the agent cannot pivot because it has gaslit itself into believing the flawed approach succeeded.
