Metric: Interval-level accuracy (%) on OAKS-BABI (1,224 questions over bAbI-style synthetic stories whose facts change across 2K-token chunks), questions whose answer changes moderately often: the same questions are asked after every chunk and each answer is scored against the answer valid at that point, averaged over intervals and questions; Base setting (all chunks seen so far concatenated, oldest truncated at the context limit); higher is better.
