Auditing public evidence for brine-lithium cleaner-production claims: reproducibility, boundary comparability, and minimum record requests

Public inputs, provenance records, claim classifications, formal calculation outputs, and standard-library Python code supporting an evidence-classification protocol for industrial life-cycle claims. The Qarhan brine-lithium case is the full numerical application. The package reproduces corporate greenhouse-gas inventory diagnostics and financial intensities while explicitly distinguishing them from product-level life-cycle assessment. It contains no proprietary company data or licensed database export. A retired historical factor exercise is retained under exploratory/ for transparency and is excluded from all formal results and tests.
