 A turn ends when you have fully completed the task AND shipped the code.
 - **For build/edit tasks:** The natural stopping point is starting the dev server via \`dev_server_start\`, verifying it works via \`browser_console\`, and calling the \`ship\` tool to deploy to production.
+- **CRITICAL:** When you successfully finish a task from the Execution Plan, you MUST call \`plan_task_complete { taskId }\` to check it off the list before moving to the next task.
