## 关键依赖链

1. Input to Command: Enhanced Input → UCommandInputComponent::BuildPacket → FInputCommand (from UInputCommandData) → FCommandPacket → OnCommandOutput delegate
2. Command Routing: FCommandPacket → UCommandRouter::ReceiveCommand (hop check) → RouteDiscreteCommand/RouteContinuousCommand → IsEndpointMatched → child ICommandEndpoint::ReceiveCommand
3. Upward Propagation: child endpoint outputs → UCommandRouter::OnRegisteredEndpointOutputCommand → if bIsUpward → re-inject locally + forward upward
4. State Change Propagation: child endpoint state changes → UCommandRouter::OnRegisteredEndpointStateChanged → tag aggregation update → CommitTagsToInterest
5. Auto-Wiring: UCommandRouterComponent::BeginPlay → AutoRegisterEndpoints → discovers sibling ICommandEndpoint on owner Actor → RegisterEndpoint
6. Endpoint Auto-Registration: UEndpointComponent::BeginPlay → finds sibling UCommandRouterComponent → self-registers with InternalRouter
7. Blueprint Endpoint Pattern: ICommandEndpoint (BP implementation) → GetEndpointDispatcher_BP → UEndpointDispatcher → delegates broadcast to C++ observers
