Report #69281

[architecture] Agent leaks memories or context from one user session into another

Enforce strict namespace or tenant ID partitioning at the vector store index level, and inject session-scoped metadata filters into every retrieval query.

Journey Context:
It is tempting to use a single global index for agent memory to save infrastructure costs and improve retrieval speed. However, cross-session contamination is a critical privacy and functional failure. Filtering at the application layer after retrieval is insufficient and error-prone. The correct architectural decision is to enforce isolation at the storage and query layer, ensuring an agent physically cannot retrieve vectors outside its current session scope.
