Hi Sasha,

Thanks for your patch and for the detailed writeup.

The important line to note is:

Assisted-by: claude-opus-4-5-20251101

So Sasha has produced a very convincingly worded writeup that's
hallucinated.

And spent a few hours trying to figure it out so I could unblock testing, but
sure - thanks.

Here's the full log:

, happy to test any patches you might have.
