Report #59400
[architecture] Cross-session memory leaking data between different users or tenants
Scope all memory writes and retrievals with a strict namespace or tenant ID prefix in the vector DB metadata, and enforce exact-match filtering on this namespace during retrieval.
Journey Context:
It is easy to treat the vector DB as a global bucket and rely purely on semantic similarity. This leads to catastrophic cross-contamination where User A's private data answers User B's query. Alternatives: separate DBs per user \(unscalable\), post-filtering \(slow, risky\). Right call: hard pre-filtering on a user/tenant namespace metadata field during the vector search.
