It delegates scoring and final fit to the native aom_chain_sweep_run Ridge-only path, selects one operator plus one positive Ridge alpha by train CV, and returns folded input_coefficients plus intercept for replay through NativeAOMRidgeGlobalRegressor. It intentionally excludes donor branch_global, MKL/kernel, row-reference-dependent preprocessing and nonlinear AOM Ridge modes; native v1 builds in CUDA-enabled configurations but this is not yet a fused GPU grinder. _Timing benchmark_: `benchmarks/cross_binding/bench_aom_ridge_global_timing.py` _See also_: [methods index](index.md).
