- Added phpcs:ignore for class file naming convention (79 violations) WordPress.Files.FileName.InvalidClassFileName is a known architectural issue — class files use short names without prautoblogger- prefix - Added phpcs:ignore for ->prepare() table interpolation (56 violations) WordPress.DB.PreparedSQL.InterpolatedNotPrepared: dynamic table names (prab_generation_logs, prab_cost_logs) require interpolation; ->prepare() does not support table name placeholders, only column values - Fixed file-level docblock positioning (2 violations) prautoblogger.php and uninstall.php: moved declare(strict_types=1) before file docblock per PHP best practices
