+    // the last thing to be added to the callout list because of the priority.
+    // However, there was a field defect where a higher priority callout of one
+    // of the endpoint was added to the list (with guard action) after the bus
+    // callout. The priority of the callout was updated to match the higher
+    // priority, but the guard action was not updated. So the following are
+    // added to the callout list in a specific order:
+    //  - First, one of the endpoints with MED_A and guard.
+    //  - Then, the bus callout with LOW and no guard. This should result in
+    //    both endpoints in the list: one at MED_A (guard), the other at LOW (no
+    //    guard).
+    //  - Finally, the other endpoint with MED_A and guard. This should result
+    //    in both endpoints in the list with MED_A priority and guard actions.
