Gpt-realtime-2 objects in tool calling bug?

Hi @dbhc,
Do you have a minimal example of the tool schema/object parameter that fails?
It would help to see whether the issue happens with any nested object or only with a specific schema shape. Also useful would be the exact error/response you get and whether it fails when registering the tool or when the model tries to call it.
A small example that works with gpt-realtime-1.5 but fails with gpt-realtime-2 would make this much easier for others to compare.
