FA-100455 / Sparse tensor canonicalization / Member archive
Sparse tensor: coalesced zero values remain stored · case 05
coalesced zero values remain stored.
Case contract
Sum duplicate coordinates and omit coordinates whose final integer value is zero.
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 |
|---|---|---|---|
| cancellation | [[0, 0, 0]] | [] | Failed |
