The authors present StateFuse, a conflict-aware replicated memory contract built on standard OpSet/CRDT merge that preserves contradictions rather than collapsing them behind overwrite rules. It defines an agent-facing semantics layer featuring immutable history, explicit conflict objects, and deterministic predicate contracts to ensure auditable correction.
- Evaluated against flat multi-value, raw-log, provenance-style, and collapsed baselines on a 282-question MemoryAgentBench slice.
- Compared methods tie on answer accuracy, but StateFuse keeps contradictions visible while collapsed surfaces do not.
- Preserving ambiguity enables safer abstention and correction than early collapse in controlled agent loops.
- Semantic handles prove important when exact prior identifiers are unavailable.
StateFuse is positioned as a safer public memory contract for contradiction surfacing and auditable correction, rather than a universal accuracy gain.
