Report #71919

[frontier] Vector RAG returns contradictory facts from different times and lacks provenance for agent memory

Maintain a structured knowledge graph \(entities, relations, timestamps, confidence\). When agent learns new info, generate a 'Patch' \(SPARQL-like or Cypher mutation\) rather than appending to vector DB. Implement conflict resolution: if new fact contradicts old \(mutual exclusivity\), lower confidence of old or mark deprecated.

Journey Context:
Naive RAG treats memory as a bag of text chunks; agents hallucinate when retrieving outdated facts or merging contradictory sources. The frontier pattern treats agent memory like a versioned database: \(1\) Extract structured triples \(Entity-Relation-Entity\) from observations; \(2\) Maintain a temporal knowledge graph with confidence scores; \(3\) Updates are explicit patches \(add/retract/modify\) with provenance \(which observation caused the update\); \(4\) Before adding, check for conflicts using semantic rules \(e.g., 'location' is functional - one value per time\). This enables agents to answer 'What did I believe yesterday?' and 'Why do I believe this?' critical for debugging and compliance.
