StateGraph tracks support dependencies among memories and checks whether they survive changed evidence before revising downstream states. It proposes candidate links from bounded cues, then counterfactually verifies them and checks for independent support. On StateChangeBench’s 10-case depth-3+ stratum, its Impact-F1 is 75.1% versus 49.1% for a CUPMem reimplementation; this is initial evidence from 50 controlled author-constructed cases.
