What

Claude Code has a fallback that can apply when the model refuses a request. The helper that decides this now accepts a responseSwapped option. The refusal-category fallback can now apply when a response was swapped, and no longer only when the message carries a marker.

Why

The refusal fallback can apply in more situations than before.
