Research direction
Start by searching the codebase for the exact error text and tracing how the AI Gateway request is built for GPT-5.5 with the OpenAI provider. The report does not name a file or test; done means identifying and addressing why the request omits the required reasoning item so this input no longer returns the reported 400.
