What
When a structured output is retracted because the request fell back to another model, the failure message now counts those retracted attempts separately, and there is a dedicated message for when no retry ever produced a valid result.
Evidence
Structured output was retracted by a model fallback and no retry produced a valid result
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
