GCAD-Global v1.2 and Nature flagship analysis package: inverting the institutional filter of the global industrial chemical accident record (1970-2025)

Version v1.9: Nature flagship submission package (editorial pre-review, sixth pass - terminology closeout). Harmonised multi-source corpus of 525,632 source records (about 305,000 chemical-relevant) from ARIA/BARPI (France), NRC/USCG (USA) and eMARS (EU), with GDELT and MEM-CN exploratory audit layers. v1.9 completes the 'cross-validated -> cross-checked' terminology change in the main-text section heading and the Figure 2 legend, so the whole package now consistently describes the two anchors as a cross-checked bracket rather than a validated point agreement. Includes the v1.8 consistency closeout (jurisdictional qualifiers synchronised across text, Fig. 5a legend and cover letter; all-spectrum wording aligned; duplicate rank correlation removed; comparison symbols unified; residual 'law' wording removed from SI), the earlier scientific disclosures (anchor distinguishability, RKI rank argument, identification/near-separation/zero-cell/pre-trend caveats), 10 Extended Data figures with Supplementary Tables 1-12, and a 2,474-word main text. Includes 68 machine-readable tables and the full 81-script pipeline.
