Report #16006

[architecture] Agent fails to connect events across time \(multi-hop reasoning over memory\)

Store memories as a temporal knowledge graph \(entities \+ relations \+ timestamps\) rather than flat text chunks, enabling structured multi-hop traversal instead of relying on the LLM to connect disjointed vector embeddings.

Journey Context:
Vector DBs are great for semantic similarity but terrible at relational or temporal reasoning \(e.g., 'Who did the user introduce me to after they changed their job?'\). Flat chunks lose the graph structure. By extracting entities/relations during memory ingestion, the agent can traverse the graph for multi-hop queries, filtering by time, which is impossible with pure semantic search.
