MemScope jointly examines execution traces, stored memories, and current code to locate failures and apply limited patches to an existing memory architecture. The paper reports 83.64% on GAIA validation using DeepSeek V3.2 with Flash-Searcher; the abstract’s 86.67% comes from a separate diagnostic experiment. Success on unseen ALFWorld tasks rose from 50.75% to 71.64%, while the median code modification ratio across 14 retained changes was 4.4%. These are the researchers’ own experiments preserving compatibility with existing records and the implementation’s identity, not a guarantee of equivalent gains in general systems.
