Gradient bucket reconstruction discards global offsets · case 03
Gradient bucket reconstruction discards global offsets.
Case contract
Given [offset,values] and total length, reconstruct exactly covered list or return None for gaps/overlaps.
Why this case matters
A toy distributed-training contract makes replica and shard contribution rules explicit without claiming framework compatibility or performance.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| chunks reversed | [2, 3, 0, 1] | [0, 1, 2, 3] | Failed |
