Auditor adds nodes to wrong Classify branch

Auditor adds nodes to wrong Classify branch consistently

Observed during: mcs-workflows audit (UC4/UC5), 2026-06-20

Problem: When clicking the "+" connector on a Classify node branch to add a downstream node (e.g., Agent), the auditor added the node to the wrong branch twice (Quote Request instead of Supplier Delay). The user had to intervene both times.

Root cause: The "+" buttons for each Classify branch are vertically stacked and close together on the canvas. Coordinate-based clicking is unreliable because:

• Branch order can shift depending on zoom/scroll state
• The click target area is small
• No verification is done after the node is added to confirm correct placement

Suggested fix:

1. After adding a node via "+", verify which branch it connected to by reading the upstream connection label in the node config panel
2. If wrong branch, delete and retry with adjusted coordinates
3. Consider using the workflow designer API/model to specify target branch programmatically rather than coordinate clicking
4. Alternatively, click the branch label text first to highlight/select the branch, then look for the "+" appearing specifically on that branch

Reproducir el flujo de Classify-branch usando el workflow designer y su node config panel, centrándose en los conectores "+" apilados. Primero comprobar si la API/el modelo del workflow designer puede identificar una rama de destino; de lo contrario, verificar la etiqueta de la conexión upstream después de añadir un nodo. Se considera completado cuando los nodos downstream se conectan de forma consistente a la rama seleccionada sin intervención del usuario.
