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

Version v1.11: Nature flagship submission package (editorial pre-review, eighth pass - reproducible detection model). 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. v1.11 corrects a non-reproducible statistic: the previously reported joint tier-interaction coefficient (beta_1 = -0.377) could not be recovered from the deposited accounting table under the stated model; the manuscript, Fig. 1c legend, Methods, Table T33 and Reporting Summary now report the reproducible per-tier income slopes (+13.3 / +3.5 / -0.3) together with a 1,000-draw country bootstrap of the minor-major slope difference (+9.9, 95% CI 1.35-45.49; monotone ordering preserved in 96.7% of draws). Includes the earlier scientific disclosures (identification boundary, near-separation, anchor distinguishability, RKI rank argument), 10 Extended Data figures with Supplementary Tables 1-12, and a 2,503-word main text. Includes 68 machine-readable tables and the full 81-script pipeline.
