[gotcha] Users trust and act on streamed AI responses before verifying completeness, leading to errors from partially-correct output

Decouple reading from acting during streaming. Keep primary action buttons \(copy, execute, insert, submit\) disabled or hidden until the stream completes and finish\_reason is confirmed. Add a brief visual transition between 'streaming' and 'complete' states to signal the shift from provisional to final output.

Journey Context:
Streaming creates an anchoring bias: users start processing and evaluating the response from the first token. By the time the response completes, they've already formed an opinion based on early tokens — which are often boilerplate, hedging, or the most obvious part of the answer. When a response goes off the rails at token 200, the user has already been reading and trusting tokens 1-199. Research on incremental information presentation shows people are more likely to accept information shown incrementally because they construct a coherent narrative as they read, making them resistant to later contradictory information. This is why AI coding assistants see high acceptance rates for partially-correct code: the developer reads the correct opening lines, mentally commits, and accepts the suggestion before seeing the buggy tail. The fix isn't to stop streaming \(users hate waiting\) but to gate actions behind completion. Let users read the stream in real-time, but don't let them act on it until it's done. The visual transition from 'streaming' to 'complete' \(e.g., a subtle border change or checkmark\) serves as a psychological signal to re-evaluate the full response.
