Replication data and code for “From Fragmented Public Data to Health-Effect Diagnostics: An AI-Agent and Machine-Learning Framework for China’s Sponge City Programme”

This dataset contains the structured data, derived analysis outputs, source register, and reproducibility materials for the manuscript “From Fragmented Public Data to Health-Effect Diagnostics”. It corresponds to the frozen v2d analysis version. The package includes the authoritative city-year panel, adjudicated sponge-city onset registry, public-source health extractions, imputation flags and confidence grades, climate and latitude classifications, DID/event-study/robustness/synthetic-control outputs, the recomputed Table 10 files, and an auditable Table 5 analysis script. Original PDFs and other third-party publications are not redistributed; the source register provides URLs or source descriptions for traceability. Empty cells indicate unavailable values, and imputation status is retained in the panel.
