Minimum dataset supporting "Heat-safe accessibility to services and cooling refuges across Chinese cities"

This minimum dataset contains the derived and aggregated data required to reproduce the principal quantitative results, figures and supplementary analyses reported in the associated manuscript. It includes 36-city residential-unit metrics, figure source data, quality-control summaries, a data dictionary and file manifest. Aggregated Beijing and Shanghai routine-POI density rasters are included, whereas raw Amap POI and road-network records are excluded because their redistribution is restricted by the provider's terms. The accompanying Code Ocean capsule contains analysis and figure-generation scripts and documents the required input schemas. Version 1.0.1 restores VARIABLE_DEFINITIONS.md and RESULT_TABLE_MAP.md, which were inadvertently omitted from the initial public archive. The derived datasets and numerical results are unchanged.本最小数据集包含复现关联论文中报道的主要定量结果、图表及补充分析所需的衍生与聚合数据。本数据集涵盖36个城市的住宅单元指标、图表源数据、质量控制汇总、数据字典与文件清单。本数据集包含聚合后的北京、上海日常兴趣点（Point of Interest，POI）密度栅格数据，但未收录原始Amap POI与路网记录，因服务提供商条款限制其重新分发。随附的Code Ocean胶囊容器包含分析与图表生成脚本，并说明了所需的输入模式。1.0.1版本恢复了初始公开存档中因疏忽遗漏的VARIABLE_DEFINITIONS.md与RESULT_TABLE_MAP.md文件，衍生数据集与数值结果均未发生变更。
