Your question is Prototype With UX and Data Model. 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 how you would design and build a product feature prototype, including the UX design, underlying data model, and the strategy, value, and tradeoffs you would present. Treat this as a practical product exercise: select reasonable assumptions, define the target user and workflow, and explain how you would validate the concept. Present a concise prototype plan that connects user needs, interface decisions, data structures, delivery sequencing, and business value.
