Evaluating confidence-gated guidance-track orientation under geometric uncertainty: reproducibility materials

Reproducibility materials for the study “Evaluating confidence-gated guidance-track orientation under geometric uncertainty.” The release contains the fixed protocol and external timestamp evidence, frozen code and choices, synthetic geometries, field manifests, candidate evidence, numerical scenario outputs, audited summaries, and reconstruction instructions. The registered design covers 360 synthetic fields and 350 Fields2Benchmark boundaries; all 3,354 planned field/configuration attempts reached terminal status (3,351 eligible complete and 3 geometrically ineligible). The primary comparisons found no observed additional benefit from the confirmation stage over calibration only: low-position choices were identical, while the few moderate-position differences had slightly unfavorable point estimates with intervals reaching or crossing zero. The materials support a geometric simulation framework and do not establish measured machinery, chemical-use, economic, environmental, or deployment-safety benefits. New author code is licensed under MIT. Author-generated synthetic geometries, numerical results and documentation are licensed under CC BY 4.0. The public archive omits copies of the 350 third-party raw and projected Fields2Benchmark boundaries and provides provenance plus reconstruction from the versioned source dataset (DOI 10.5281/zenodo.14524735); original third-party terms remain applicable.
