What Tarun demonstrated

Built a complete battery-passport compliance package for a single cell, including field classification, access-tier design, supplier gap attribution, and two submission-ready data requests. Also ran a reproducible carbon-footprint calculation in code and correctly interpreted the result, showing that upstream raw-material sourcing drives most of the footprint and should be the first compliance focus.
