The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

DCM-Agent achieves an average performance improvement of 11%-21% across seven optimization benchmarks, with a knowledge inheritance phenomenon where memory constructed by larger models guides smaller models toward superior performance.

C2weakest assumption

That historical solutions from prior problems can be reliably clustered and distilled into generalizable, non-overfitting guidance that transfers to new optimization instances with multi-paradigm ambiguity.

C3one line summary

DCM-Agent improves LLM performance on multi-paradigm optimization problems by 11-21% via dual-cluster memory construction and dynamic inference guidance.
