The Memory Kept the Old Fact After the World Changed
StateMemBench separates current-state answers from superseded facts across 234 multi-session scenarios.

Summary
StateMemBench separates current-state answers from superseded facts across 234 multi-session scenarios.
The benchmark tests whether an agent updates its working world when facts, constraints and decisions change, rather than merely retrieving something that was once true. The authors report that a state-first method improved current-state accuracy over same-backbone and existing-memory baselines, and that a single-call wrapper added 32 to 67 points across six backends; absolute benchmark performance remained limited, keeping the result squarely in research territory.
