When a switch case test contains a logical expression (|| or &&), visiting the expression creates multiple CFG blocks for short-circuit evaluation and changes current_node_ix. The condition instruction must be appended to the block BEFORE visiting the expression, not after. This matches the pattern used in visit_if_statement and ensures the condition instruction is placed in the case entry block, making it discoverable by code that identifies case test blocks. Before: ```rust self.visit_expression(expr); // moves current_node_ix cfg.append_condition_to(cfg.current_node_ix, ...); // wrong block After: let condition_block_ix = cfg.current_node_ix; // save before self.visit_expression(expr); cfg.append_condition_to(condition_block_ix, ...); // correct block
