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.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what a swapped response is or what the reader sees when this fallback applies.
