FLX-3203: positional row does not match the declared column count

Family: seam/conformance (the 3000 band)

Rows travel as arrays aligned to the ordered header (KERNEL-SPEC §8), so a row with a different length has no alignment: value k is not column k. Pass the row as a mapping if the producer cannot guarantee the declared order.
