Report #7360

[architecture] Bleeding memories across different user sessions or workspaces in a shared vector index

Namespace or partition memory stores by a strict user\_id or session\_id at the index level, and enforce scoping in the retrieval metadata filter.

Journey Context:
A naive global vector store will retrieve facts from User A when User B asks a similar question. This is a massive privacy leak and logic error. Metadata filtering on user\_id is necessary, but even better is strict index partitioning \(e.g., separate collections or namespaces per tenant\) to guarantee zero cross-bleed at the physical level and improve search latency by reducing the search space.
