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

Version v1.7: Nature flagship submission package (editorial pre-review, fourth pass). 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. v1.7 responds to the figure budget: the main text is compressed to 2,466 words for a five-composite-figure Article, and two figure labels are re-laid-out (Fig. 4b annotation moved to open space; Fig. 5a RKI labels de-collided). Earlier passes disclosed the anchors' statistical distinguishability, corrected the RKI rank-invariance argument, clarified jurisdictional scope, stated the identification/near-separation/zero-cell/pre-trend caveats, corrected the cover letter, and moved the 12 Extended Data tables to Supplementary Information (Extended Data now 10 figures, within the 10-item cap). Includes 68 machine-readable tables and the full 81-script pipeline.
