Seat-map fields were independently confirmed against recorded evidence for United Airlines. Seat codes, cabin assignments, row structure and cabin totals passed independent source verification. Spacing and facility placement remain schematic unless the map explicitly says otherwise. The map cannot render unless its seat-by-seat count reproduces the published totals exactly (48J + 21W + 188Y = 257 on this aircraft). Per-seat notes are rewritten into plain-language warnings for row selection.
