+# "fix(csv): handle trailing empty field at EOF without newline"
+#
+# When a CSV file ends with a row like "a,b," (no trailing newline, last field
+# empty), the parser used to drop the empty field, causing "expected N values
+# per row, but got N-1". The fix adds an else-if branch in final_state to emit
+# the empty value when column > 0.
