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

Version v1.14: Nature flagship submission package (editorial pre-review, eleventh pass - AI-trace cleanup). A full pass with four style skills (stop-slop, no-ai-slop, bladerhumanizer, lieflat-less-ai-tone) found no banned AI vocabulary (no delve/leverage/crucial/pivotal/underscore/testament, no 'serves as', no superficial -ing riders, no colon reveals) but a high em-dash rate: 17 in the manuscript, 10 in the cover letter and 16 in the SI. These were reduced to 3 in the manuscript (only the official CRediT terms 'writing-original draft', 'writing-review and editing') and zero in the cover letter and SI, replaced with commas, semicolons, colons and parentheses. A negative-contrast closer ('...an executable research agenda, not a metaphor') and a verbless fragment ('; institutions do.') were rewritten as complete sentences, and repeated 'robust' phrasings were varied to 'stable'. No number, citation, qualifier or argumentative step changed (references still first-appearance ordered 1-42; abstract 199 words; main text 2,483 words). The package otherwise matches v1.13.
