A Reproducible Checkpoint-Recovered Posterior Benchmark for GW150914: Artifacts, Stability Tests, and Exploratory Astrophysical Projections

This record archives a reproducible research package for a benchmark-oriented reanalysis of GW150914 based on a checkpoint-recovered posterior state. The package contains the manuscript PDF, LaTeX source, bibliography, derived tables and figures, and the scripts needed to rebuild the reported research artifacts from the included posterior products. The archived materials support manuscript-level and artifact-level reproducibility. A reader can regenerate the paper, figures, tables, and derived summary products directly from the packaged files. This record does not claim a full end-to-end rerun from raw detector strain to a newly converged collaboration-grade posterior. Rather, it provides a transparent and reproducible bridge from checkpoint-recovered posterior artifacts to stability analyses and exploratory astrophysical projections, while clearly identifying the additional inference chain required for full astrophysical posterior estimation. This deposition is intended as an open-science benchmark and methods-focused resource for reproducibility studies, posterior artifact analysis, and transparent workflow documentation built around GW150914 public-data products.本存档记录了一个面向基准测试的、基于经检查点恢复的后验状态（checkpoint-recovered posterior state）的GW150914再分析可复现研究包。该研究包包含稿件PDF、LaTeX源文件、参考文献列表、衍生表格与图表，以及用于从附带的后验产物（posterior products）中复现已报道的研究产出物所需的脚本。 本次存档的材料支持稿件级与产出物级的可复现性。研究者可直接通过打包文件重新生成论文、图表、表格及衍生汇总产物。本存档并未宣称可完成从原始探测器应变数据（raw detector strain）到新收敛的合作组级后验结果（collaboration-grade posterior）的全端到端重运行（end-to-end rerun）。相反，本存档提供了一条透明且可复现的桥梁，连接经检查点恢复的后验产物与稳定性分析（stability analyses）及探索性天体物理预测（exploratory astrophysical projections），同时明确标注了完整天体物理后验估计所需的额外推理链（inference chain）。 本次存档旨在作为开放科学基准（open-science benchmark）与方法导向资源，服务于围绕GW150914公开数据产物开展的可复现性研究、后验产物分析以及透明工作流文档（workflow documentation）编制工作。
