Report #12447

[architecture] Agent acts on outdated or contradictory memories because the vector store returns conflicting facts

Implement memory upsertion and deduplication. Before inserting a new fact, search for existing overlapping facts and use an LLM to resolve conflicts \(update or delete the old memory\) rather than just appending.

Journey Context:
Naive memory implementations just append new facts. If a user changes their preference, both facts exist. Retrieval might pull the outdated one. Appending causes context pollution and contradictions. Tradeoff: Upsertion requires an extra LLM call per memory insertion, increasing latency, but is strictly necessary for maintaining accurate stateful facts over time.
