Report #3204
[architecture] Vector embeddings strip away temporal context
Augment memory payloads with strict metadata \(timestamps, session IDs\) and use hybrid search \(vector similarity \+ metadata pre-filtering/post-filtering\) to enforce temporal constraints.
Journey Context:
Pure vector similarity treats time as irrelevant. 'I deployed the API' embedded today is nearly identical to 'I deployed the API' embedded a year ago. When the user asks 'What did I deploy recently?', pure vector search might return the year-old memory. Metadata filtering allows the agent to restrict the search space to a specific time window before applying semantic similarity, ensuring temporal relevance.
