CSR row-pointer intervals are treated as nonempty row markers.
Case contract
Return the number of empty rows in a valid CSR row pointer array.
Why this case matters
A small offline sparse-array operation has explicit coordinate and storage semantics.
One recorded failure

| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| interior empty | 3 | 1 | Failed |
