Report #77488

[architecture] Agent fails to answer questions requiring connecting two separate facts stored in memory

Structure long-term memory as a knowledge graph or implement iterative multi-hop retrieval, allowing the agent to traverse relationships between entities rather than relying on a single vector search.

Journey Context:
Vector stores are great for unstructured semantic similarity but terrible for relational queries. If Fact A is 'User works on Project X' and Fact B is 'Project X is managed by Alice', a vector search for 'user's project manager' might only retrieve Fact A. Graph structures or multi-step agentic retrieval are required to bridge the gap between isolated semantic islands.
