[architecture] Routing all data through vector retrieval when it fits in the context window

Use long-term memory \(vector DB\) only for cross-session persistence or datasets exceeding the context limit. Keep current workflow state directly in the context window.

Journey Context:
Developers often treat RAG as the default memory pattern, but retrieval introduces latency, embedding cost, and information loss \(top-K truncation\). If an agent is working on a single session and the required history/state fits within the model's context window, passing it directly is strictly superior because the LLM gets perfect, lossless attention over the data. Memory-first design means knowing when not to use external memory.
