Report #12443

[architecture] Storing everything in the vector database instead of managing active context

Use a tiered memory system \(Core/Working memory in-context, Archival/Recall memory in vector DB\). Only move to vector DB when context limits are hit or for cross-session persistence.

Journey Context:
Developers often treat vector DBs as a drop-in replacement for context. But retrieval is lossy; if the agent needs a fact now, it should be in the prompt. Vector DBs require search queries, which might miss the exact nuance needed for the current step. Tradeoff: context window is limited and expensive. Virtual context management solves this by actively moving data between tiers.
