These repositories require PDO and use exclusively parameterized prepared statements — no raw SQL concatenation. WordPress-specific data (users, options, capabilities) is accessed via $wpdb through the plugin’s Bridge layer (WpUserRepository, WpConfigRepository, etc.). See src/Bridge/PdoFactory.php for the connection factory.
