Retrieval Is Solved. Why Agent Memory Still Isn't Safe.

This is part of the Self-Correcting Systems research series. If you are new here: Start Here. The public harness is at github.com/keniel13-ui/ai-memory-judgment-demo.

The AI memory ecosystem has spent three years solving a hard problem.

How does an agent preserve state across sessions? How does it retrieve the right context without overloading the window? How does it manage long histories and surface the right memory at the right moment?

LangChain, LlamaIndex, MemGPT/Letta, and Zep have all built real things toward that problem. Vector stores, hybrid search, semantic similarity, context compression — the tooling is mature and the research is serious.

I am not here to argue with any of that.
