CUHK and Zhejiang University Question Whether AI Agent Memory Is Just a Memo

你的AI Agent越用越蠢？港中大、浙大戳破「记忆」的谎言

CUHK and Zhejiang University researchers argue that mainstream Agent memory is retrieval-based memo storage, not true memory, citing an Ω(k²) case requirement for compositional tasks and a PoisonedRAG result where 5 adversarial texts reached a 90% attack success rate.

Why it matters: HKR-H/K/R all pass: the hook is concrete, the summary gives Ω(k²) and 90% attack success, and the issue matters to agent-memory and RAG-security builders. Strong research signal, not a same-day model-release event.
