+Subject: [PATCH] swig: Add missing %template for
+ std::vector<TransactionPersistence>
+
+MergedTransaction::listPersistences() returns std::vector<TransactionPersistence>,
+but no SWIG %template was declared for this type. Without it, SWIG wraps the
+return value as an opaque pointer instead of a Python list, causing memory leak
+warnings and preventing Python code from iterating over the values.
+
+Add the missing template, matching the existing TransactionStateVector pattern.
