Replica gradients ignore local sample counts · case 02
Replica gradients ignore local sample counts.
Case contract
Given [gradient_mean, example_count] rows, return the elementwise global example mean; zero-count rows contribute nothing and total zero returns [].
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.
