Add Moving Points to a Map (Request-driven updates)

Add Moving Points to a Map (Request-driven updates) Implement a request processor for a map that maintains a set of moving points. Each request may add a point, update its state (e.g., position/velocity), or query positions at a given time. Note: The original post lacks the concrete request types, fields, and time/physics rules needed for a fully specified coding prompt, so only the title is retained.
