Report #68131

[gotcha] Users act on incomplete streaming responses before the AI finishes generating

Disable action buttons \(copy, submit, execute\) until the stream completes. Add a visual 'still generating' indicator. Never enable code execution or form submission from a partially streamed response.

Journey Context:
Streaming creates a powerful illusion of completeness—users start reading immediately and may act on what they see before the response is done. This is especially dangerous when the AI starts with one answer then pivots \('Actually, the better approach would be...'\) or when it generates code that appears complete but is missing closing brackets or final lines. Users who copy-paste or execute partial code get errors. The fix is simple but often overlooked: gate all actionable UI behind stream completion. The streaming UX should make it visually obvious that generation is ongoing \(animated cursor, pulsing border\) and prevent premature action.
