Your question is Defining Design Handoff Readiness. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to decide a design was finished and ready for handoff. How did you determine it was ready, what criteria did you use, and how did you handle any open questions or pushback before engineering started building it?
