The join key is ISO3 -> ISO 3166-1 NUMERIC, NOT the BACI numeric code: BACI uses USA=842 and France=251, but the TopoJSON feature ids are ISO-numeric, so USA->840 and France->250. ISO3 codes absent here are either non-ISO Comtrade aggregates (S19/R20/ZA1) or small territories with no polygon in the coarse 110m basemap; see 'unmapped'. Predecessor/historical codes are stitched into their current ISO3 upstream and never appear as separate keys.",
