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

Version v1.15: Nature flagship submission package (editorial pre-review, twelfth pass - container-metadata cleanup after a watermarks-remover check). Ran the watermarks-remover skill set (clean-user-facing-text Layer A + stylometry, and a local container-metadata scan because the remove-ai-marks HTTP service was not running). Result: the prose is clean (0 invisible-Unicode hits; stylometry composite 0.0325 vs a 0.65 threshold; AI n-gram density 0.0; density tier low; no rewrite indicated) and no C2PA, SynthID or vendor AI watermarks were found. Actionable tooling provenance was removed: the Word files no longer carry python-docx core properties or the Microsoft Macintosh Word app property or the template thumbnail (author now set, title written, dates set to the release date), and the three Extended Data PDFs whose embedded /Title still referenced the pre-renumbering figure names were corrected. Benign items left unchanged: the UTF-8 BOM in 42 machine-readable CSVs (intentional, Excel-friendly) and ideographic spaces in the Chinese README. Package otherwise matches v1.14.
