Shard values are placed by list position instead of declared offsets · case 04
Shard values are placed by list position instead of declared offsets.
Case contract
Given [offset,value] pairs and output length, return dense list with None for unowned positions; duplicate offset last wins.
Why this case matters
A toy distributed-training contract makes replica and shard contribution rules explicit without claiming framework compatibility or performance.
