Describe the bug

In the SDK, these runs don't appear as child runs at all.

Reproduction repo

not available

To reproduce

not at the moment

Additional information

How can I reliably show my users, how many of their sub tasks failed, while in progress/before I get the final output? Without idempotency I can check the status of the run.relatedRuns.children, but tasks that are cached do not appear in this array.

[cachho]

as far as I can tell, the run object returned by runs.retrieve contains no info about any cached child runs. So there's no way to show progress until it's completed and you can validate the output.
