Report #99031

[gotcha] Model refusals are first-class outputs, not exceptions, and break structured UIs when ignored

Check for the \`refusal\` content type or \`response.refusal.delta\` stream events explicitly. Render a polite, specific message and keep the rest of the UI responsive. Do not treat refusals as HTTP 500s or leave the user staring at blank output.

Journey Context:
Safety refusals are part of normal model behavior, but most SDK examples branch on \`output\_text\` and omit refusal handling. When a refusal arrives, the parser throws or the UI shows empty space, which feels like a bug. OpenAI's structured-output documentation makes refusal a typed field so you can present it gracefully and offer a safer rephrase. Design the refusal state just like an empty-state or validation message.
