[gotcha] AI response cuts off mid-stream with no UI feedback when content filter triggers

Parse the finish\_reason from the final streaming chunk. Map 'content\_filter' to a distinct UI state explaining the response was filtered—not incomplete or errored. Never show a trailing ellipsis or spinner that implies more content is coming. Buffer the final chunk metadata rather than treating each token as fire-and-forget.

Journey Context:
When content moderation triggers during streaming, the stream simply ends with finish\_reason='content\_filter'. Most implementations only handle the 'stop' finish reason and treat everything else as a network error or incomplete response. Users see a sentence that trails off and think the app is broken. The fix requires parsing the finish\_reason from the final chunk and mapping it to a specific UI state. The tradeoff: you must buffer the final chunk's metadata rather than treating each token as fire-and-forget, adding minor implementation complexity.
