Report #70557

[architecture] Relying solely on vector similarity for memory retrieval returns semantically similar but contextually irrelevant memories

Always attach structured metadata \(user\_id, session\_id, project\_name, timestamp\) to memory vectors and use hybrid search \(metadata filtering \+ vector similarity\) to constrain retrievals to the current operational scope.

Journey Context:
Vector embeddings collapse meaning into a single dimension. 'Fix the login bug' for Project A is semantically identical to 'Fix the login bug' for Project B. Without metadata pre-filtering, the agent will pull in the wrong context and apply it, causing catastrophic cross-contamination of tasks.
