  * CheckPrivileges
- * This rule should only check once, because after check would set setPrivChecked in statementContext
+ *
+ * The privChecked flag is on StatementContext to support view permission passthrough:
+ * when InlineLogicalView expands a view, the outer CheckPrivileges has already verified
+ * the view-level permission, so the inner tables should not be re-checked.
+ *
+ * For CTEs, since LogicalCTEConsumer is a leaf node and the producer subtree is not
+ * traversed by ColumnPruning, we override visitLogicalCTEConsumer to explicitly
+ * traverse the producer plan and check privileges on its tables.
