#retrieval

Even with good memories and trust scores, you still need something to decide which memories actually get used for a specific question. That is the arbitration layer.

What actually happens when an AI uses long-term memory to answer a question - the retrieval, arbitration, and response flow that makes memory-backed answers fundamentally different.

As memory grows, the first performance problem is not storage - it is retrieval. Why naive vector search does not scale, and the techniques that keep queries fast at millions of memories.
