[gotcha] AI refusal messages look identical to normal responses in UI because refusals are returned as text not structured errors

Use the model structured refusal field when available \(OpenAI refusal field in the response message object\) to detect refusals programmatically rather than parsing response text for apology patterns. Render refusals with distinct UI treatment such as different styling or icon so users understand it is a system constraint not a generated answer.

Journey Context:
Models return refusals as regular text content like I am sorry but I cannot assist with that. In the API response this looks identical to a successful completion with the same structure and finish\_reason of stop. Naive implementations just display the text making refusals indistinguishable from actual answers. Users may think the AI is being unhelpful rather than hitting a safety boundary. OpenAI added a dedicated refusal field to the response message object specifically to solve this, but many implementations still only look at the content field. The UX fix is two-part: detect refusals programmatically using the structured field, and render them with distinct visual treatment that communicates this is a boundary not an answer.
