/// C2S invokes. Strategy is return-real-ids-first: the client spawns GM entities locally
/// (GM invoke call sites ignore the return), the server records the ids so the debug
/// panel can manage them. If a command proves to wait for a server broadcast, the push
/// (SyncLogicVehicleEnter etc.) gets added for that command.
