Report #100710

[architecture] User asks a question that requires connecting a fact from last week with a fact from today—how do I retrieve the chain?

Use a hybrid memory: vector similarity for semantic lookup, plus a knowledge graph for relational hops and explicit timestamps for temporal ordering. At query time, seed graph traversal from entities in the question and rank memories by combined relevance, recency, and graph proximity.

Journey Context:
Pure vector search fails when answer evidence uses different words than the query or is spread across disconnected moments. HippoRAG demonstrated that a knowledge graph plus Personalized PageRank can answer multi-hop questions in one retrieval step, outperforming iterative RAG. Adding temporal metadata and time-decay lets the agent respect sequence and recency.
