[architecture] Storing current working state in vector database

Keep short-term, highly structured working memory \(current task, variables, scratchpad\) in the context window or a key-value store, reserving vector stores for long-term episodic/semantic memory.

Journey Context:
Vector DBs perform approximate nearest neighbor search, which loses exact state. If an agent needs to know the current target file path, a vector search might return a similar but wrong path from a previous session. Context window provides exact, sequential reasoning; KV stores provide exact lookups. Vector is for fuzzy semantic recall.
