* closes: #60867 **Problem** The "Triggered DAG" button only appeared after the parent task completed execution. During RUNNING/QUEUED states, the button was completely hidden. **Root Cause:** The underlying TriggerDagRunLink reads the target redirection URL directly from XCom metadata using a specific key. By default, this XCom entry was populated downstream during the task-runner's standard finalize() routine at the very end of the task instance lifecycle. **Solution:** Modified the execution routine to eagerly calculate and push the TriggerDagRunLink URL tracking payload to XCom using context["task_instance"].xcom_push right inside the active _trigger_dag_af_3 execution block, immediately after the target run initialization occurs and before the trigger exception is raised. This enables the FastAPI REST API /links endpoint to immediately serve the rich metadata payload, allowing the new Airflow 3 React UI to successfully render the clickable "Triggered DAG" navigation button the exact millisecond the child DAG is queued. <img width="1852" height="1123" alt="Screenshot from 2026-05-22 16-27-12" src="https://github.com/user-attachments/assets/6e18ad5a-4534-4e85-a584-0304f6a7c764"; /> -- This is an automated message from the Apache Git Service.
