A self-contained native engine (a C interface over C++ host logic) for stochastic actor-oriented models (the model family of 'RSiena'), exponential random graph models (cross-sectional, temporal, and separable temporal), and models for binary actor attributes, callable from R without a Python runtime. The CRAN build is CPU-only (C++17, multi-threaded with 'OpenMP'); a 'CUDA' backend implements the same interface and is built separately from source. The data preparation, host statistics ('RSiena' Appendix B conventions), and moment targets are validated bit-for-bit against the reference implementation and reproduce 'RSiena' targets on public datasets to machine precision; the estimators match 'RSiena', 'ergm', 'btergm', and 'tergm' on public benchmark models. The method-of-moments estimator returns standard fit objects with the simulated networks on request, and the simulator also plugs into the unmodified 'RSiena' estimator.
