Your question is Real-Time Inventory Tracking. 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).
Design a real-time inventory positioning and tracking service that updates stock availability across warehouses and retail stores.
Clarify the consistency, freshness, reservation, and reconciliation requirements before proposing the design. Cover event ingestion, inventory state management, APIs, failure recovery, observability, and any appropriate ML components without treating ML as the source of truth.
