Summary

CausalCache spends a fixed visual-memory budget on the past events with the highest conditional utility.

On OSWorld-Verified, restoring selected history images was worth about 13 success points over summary-only memory, although same-budget allocation methods were indistinguishable on desktop. A zero-shot mobile test produced a 3.7-point overall gain and an 8.6-point gain on the predeclared memory-critical split.
