[architecture] Agent losing track of state in long sessions because it relies solely on the context window

Adopt a 'memory-first' architecture. Treat the context window as a volatile L1 cache. Continuously summarize and offload state to an external long-term store \(L2/L3\) mid-conversation, and retrieve it explicitly when needed, rather than appending the entire history to the prompt.

Journey Context:
Developers often just pass messages\[\] to the LLM, assuming the context window is infinite or that summarization is lossy. As the context window fills, attention mechanisms degrade, costs skyrocket, and the agent eventually hits the token limit and crashes. The tradeoff is that offloading requires explicit read/write logic and summarization can lose details, but it is strictly necessary for unbounded task completion. The context window should only hold what is immediately relevant.
