Research direction
Start by reproducing the reported ZeRO level 3 failure with an nn.Parameter, then trace the partitioning path that handles nn.Linear. Compare how the two parameter types are treated and identify the existing tests covering ZeRO-3. Done means nn.Parameter works under ZeRO-3 without the reported failure and the behavior is covered by a regression test.
