[gotcha] Streaming AI response interrupted by content moderation after tokens already rendered to user

Treat all in-flight streamed tokens as provisional UI state. Render them with visual distinction \(reduced opacity, 'generating…' label, italic\) and only commit to final display once the stream closes with a finish\_reason of 'stop'. Implement a graceful rollback UI for mid-stream interruptions that replaces partial content with a neutral message rather than abruptly deleting it.

Journey Context:
When using streaming APIs with content moderation, moderation is evaluated asynchronously. Tokens can be delivered to the client before a moderation flag is raised, especially for edge-case content that requires more evaluation time. If your UI renders each streamed token as permanent content the moment it arrives, a mid-stream refusal forces an impossible choice: leave partial content visible \(which may be confusing or inappropriate\) or abruptly remove it \(which is jarring and breaks trust\). The counter-intuitive insight is that streaming's primary UX benefit — immediate feedback — directly conflicts with moderation's need to evaluate near-complete context. Teams often discover this only in production when edge cases hit moderation mid-stream. The fix is architectural: your streaming renderer must have two states — provisional and committed — and the transition between them is gated on stream completion.
