row selection matches columns instead of rows.
Case contract
Return entries from exactly the requested row, preserving their column/value pairs in column order.
Why this case matters
A small offline sparse-array operation has explicit coordinate and storage semantics.
One recorded failure

|---|---|---|---|
| requested row | [[2, 1, 5]] | [[1, 0, 4]] | Failed |
