Lifecycle** + +1. **Message Reception** (MessageHandler) + - ROS 2 MutoAction message received + - MessageRouter extracts payload and creates StackRequestEvent + - Event published to EventBus + +2. **Stack Analysis** (StackManager) + - StackAnalyzer determines stack type and execution requirements + - StackAnalyzedEvent published with analysis results + +3. **Orchestration Start** (OrchestrationManager) + - DeploymentOrchestrator receives analysis and starts orchestration + - Determines appropriate pipeline based on requirements + - OrchestrationStartedEvent published + +4. **Stack Processing** (StackManager) + - StackProcessor handles merging and expression resolution + - StackProcessedEvent published with processed manifest + +5. **Pipeline Execution** (PipelineEngine) + - PipelineExecutor runs appropriate pipeline (apply/start/kill) + - Each pipeline step coordinates with plugin services + - PipelineCompletedEvent published on success + +6. **Orchestration
