FA-100469 / Sparse tensor canonicalization / Member archive
Sparse tensor: columns inside each CSR row are not canonicalized · case 04
columns inside each CSR row are not canonicalized.
Case contract
Sort each CSR row by column while keeping each column paired with its original value.
Why this case matters
A small offline sparse-array operation has explicit coordinate and storage semantics.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| paired sort | [[4, 1], [50, 20]] | [[1, 4], [20, 50]] | Failed |
