Crumple: derived dataset, QC pipeline and analysis code for "Crumple: An Empirical Crush and Force Envelope for the Modern Australian Vehicle Fleet"

Derived dataset, quality-control pipeline, analysis code, reports, and figures behind the paper "Crumple: An Empirical Crush and Force Envelope for the Modern Australian Vehicle Fleet". Contains: the flattened NHTSA bulk pull (10,876 crash-test records); QC outputs with per-row reject reasons; the Australian-fleet-matched cohort; dynamic-crush derivations from accelerometer double-integration; barrier load-cell force results; impact-height (AHOF) results; fitted quantile-envelope design tables; all analysis scripts; machine-generated QC/validation reports; and the paper's figures including the Annex C design-artefact sheets. Raw cached NHTSA records are not redistributed — they are public data re-buildable with the included fetch scripts. Data, reports and figures: CC BY-NC 4.0. Code: PolyForm Noncommercial 1.0.0.
