[architecture] Believing massive context windows eliminate the need for external vector memory

Use external memory for persistent, structured knowledge and massive document corpora. Reserve the massive context window for the current working set, complex instructions, and recent conversational flow.

Journey Context:
While 1M\+ token windows exist, filling them degrades instruction following, increases latency exponentially, and costs a fortune per inference. Furthermore, context windows are ephemeral. External memory \(RAG/Graph\) remains crucial for cross-session persistence, cost control, and maintaining high attention density on the actual task at hand. The tradeoff is architectural complexity in managing RAG, but it is strictly required for production cost-efficiency and persistent state.
