The reason these issues have sat is I just didn't have Claude API access. I just funded my personal account with $5 to get this to work and now I see the issue.

Claude streaming has data: {"type": "ping"} which we of course don't support leading to the misleading choices fix. I'll have a PR up in an hour.

I believe this will fix it - #556

You could take the small patch in non-test code and confirm if you'd like.
