+  summary: Initiate payment batch by quote reference
+  description: |
+    Executes batch payment from a previously created multi-quote reference. If any quoted item
+    uses a raw `card` destination, that item's original quote must already include `exp_month`
+    and `exp_year`. Card-recipient AML screening occurs during execution, not quotation. An
+    unchanged payment item reuses its persisted compliance decision on idempotent execution
+    replay, avoiding a duplicate AML call. A definitive denial terminates that payment with
+    public `failureCode: failure_restriction` and `failureReason: aml_denied`.
