[architecture] Trying to answer complex temporal questions using standard semantic vector search

Augment vector search with a temporal index \(e.g., time-bucketed retrieval or time-weighted ranking\) and a knowledge graph for multi-hop reasoning.

Journey Context:
Vector embeddings flatten temporal relationships. 'After' or 'before' are relational concepts, not semantic ones. If a user asks 'What did I change after the deployment last Tuesday?', pure vector search will return things about 'deployments' and 'changes' regardless of time. Time-weighted search helps, but for true multi-hop temporal reasoning, you need a graph \(entity-relation extraction\) or a strict chronological log that the LLM can scan sequentially.
