Contextual Agentic Memory is a Memo, Not True Memory

ArXi:2604.27707v1 Announce Type: new Current agentic memory systems (vector s, retrieval-augmented generation, scratchpads, and context-window management) do not implement memory: they implement lookup. We argue that treating lookup as memory is a category error with provable consequences for agent capability, long-term learning, and security. Retrieval generalizes by similarity to d cases; weight-based memory generalizes by applying abstract rules to inputs never seen before.
