[architecture] Assuming the LLM's native context window is the only memory available for large tasks

Implement virtual context management using paging. Use the LLM's context window as main memory \(RAM\), and external storage \(disk\). Give the agent explicit tool calls \(e.g., memory\_search, memory\_insert, archival\_search\) to swap data in and out of its working context.

Journey Context:
Standard RAG just appends retrieved text to the prompt. If the prompt fills up, the agent crashes or truncates important instructions. MemGPT introduced the OS metaphor: the context window is RAM, and the agent must actively manage what is paged in or out. This allows agents to process documents vastly larger than their context window. The tradeoff is increased agentic complexity \(the LLM must learn to use memory tools correctly\), but it is the only way to handle unbounded context.
