Tensor views: broadcasted singleton gets zero stride · case 02
broadcasted singleton gets zero stride.
Case contract
Broadcast an input axis to target size; unchanged dimensions keep stride and expanded singleton axes get stride zero.
Why this case matters
Dense tensor views rely on consistent logical coordinates and physical storage addresses.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| expand row | [[3, 2], [1, 1]] | [[3, 2], [0, 1]] | Failed |
