[architecture] Agent storing contradictory memories leading to hallucinations

Implement a read-before-write memory update strategy. Before inserting a new fact, search the memory store for existing related facts. If a contradiction is found, use an LLM to resolve it and update the existing memory record rather than appending a new one.

Journey Context:
Append-only memory stores lead to contradictions \(e.g., User lives in NY then User moved to CA\). The agent might retrieve both and hallucinate conflicting realities. Alternatives: TTL on all memories \(too aggressive\), pure append \(causes conflicts\). The right call is read-before-write with LLM-based resolution and upserts, trading write latency for consistency and preventing context pollution from conflicting facts.
