What Sam demonstrated

Built a complete battery-passport compliance package for a single cell: classified regulated fields as known/compute/gap, designed public/legitimate-interest/restricted passport views, and traced every remaining gap to the supplier tier that owns it. Also computed the cell’s carbon footprint from code, identified raw materials as the dominant emissions source, and drafted actionable supplier requests to close the highest-priority data gaps.
