Report #13870

[architecture] Long-running agents exceed context limits or lose the plot because early context is truncated or scrolled out of the window

Implement rolling memory consolidation. When the working context window reaches a threshold \(e.g., 80% capacity\), summarize the oldest N turns into a condensed semantic block, and replace them in the prompt with the summary.

Journey Context:
Simply truncating old messages destroys the agent's ability to track long-term dependencies and multi-step goals. Simply keeping all messages hits the token limit. The tradeoff is the latency/cost of the summarization LLM call vs. the loss of granular detail. Summarization preserves the 'plot' and high-level goals while freeing up context space for new reasoning. This mimics human sleep consolidation.
