What Hem demonstrated

Built a battery-passport compliance package end to end: calculated the cell’s carbon footprint in code, separated regulated fields into public, legitimate-interest, and restricted views, and traced unresolved GAP fields to the supplier tier most likely to own them. Also drafted supplier requests aimed at closing the highest-priority upstream data gaps before passport submission.
