[architecture] I stored memories in a vector DB but the agent still contradicts itself

Add a memory layer above the vector store that extracts facts, resolves conflicts, and updates records; a vector DB is retrieval infrastructure, not a memory system.

Journey Context:
A vector database provides approximate nearest-neighbor search; it does not know what is a fact, when facts change, or how to merge duplicates. The mem0 comparison lists extraction, deduplication, contradiction resolution, and recency weighting as capabilities a real memory layer adds on top of vector infrastructure. Without these, agents retrieve semantically similar but contradictory snippets and hallucinate a synthesis. Build or adopt a memory layer that writes structured records and treats updates as first-class operations.
