What Umansh demonstrated

Built a battery-passport compliance package end to end for a single cell: classified regulated fields, separated public vs legitimate-interest vs restricted access views, calculated a four-stage carbon footprint from source data, and traced remaining data gaps to the supplier tier that owns them. Also drafted field-specific supplier requests tied to the regulation and compliance deadline, showing practical judgment about what can be requested and from whom.
