batch_create_process_nodes_FieldValueRef

Field value reference, used only for Condition.left. kind is fixed to field and must include node and fieldId; literal / systemField / record / template / empty are not allowed. Virtual fields in manual nodes should still use normal node + fieldId, for example approve_step + opinionSummary; do not write internal suffixes into nodeAlias.
