Data and analysis code for "When is a transferred surrogate safe to bypass power flow? Feeder-specific qualification of conformal voltage-security screening"

This record provides the machine-readable evidence, publication-asset sources, and analysis code supporting the manuscript “When is a transferred surrogate safe to bypass power flow? Feeder-specific qualification of conformal voltage-security screening.” The package supports transparent verification and reproduction of the principal figures, tables, and reported summary analyses. It includes source data and rendering assets for the seven main figures, machine-readable sources for the seven main tables, unit-level calibration and reliability evidence, model-comparison records, and computational-accounting data. The repository is a publication reproducibility package rather than the complete historical development environment or an end-to-end model-training framework. It does not rerun surrogate training, regenerate the complete 144,000-state experimental corpus, or reproduce state-level UTC-day bootstrap resampling. Third-party SimBench networks are not redistributed and remain subject to their original terms. Computational timing results are specific to the hardware and workload conditions documented in the associated manuscript and repository. Original source code is licensed under the MIT License.

Version 1.1.0 adds the frozen prospective commissioning protocol, unit-level prospective outcomes, confirmation results, stratified summaries, leave-one-archetype-out sensitivity, and associated integrity records supporting Methods 2.4 and Results 3.6 of the manuscript. No retrospective scientific results were changed.
