Production agent dev: every AI memory tool is a vector store in a trench coat

A developer building production agents complains that almost every memory tool is just a vector store with a wrapper: embed conversations, store them, and retrieve whatever looks most similar.
Real-world failure: a user said they moved from Delhi to Mumbai in session 4, and in session 7 the agent recommended a Delhi restaurant because the old embedding scored higher. When a preference changes, the store keeps both versions and the model picks randomly — none of which is a model problem, but the memory not knowing what changed.
What he wants: typed extraction (fact vs preference vs event), contradiction handling so old facts get replaced, and entity resolution so one person mentioned 10 ways stays a single entry. He's asking the community for options.
