Control characters removed by kses (wp_kses_no_null: C0, \\0 sequences) or ControlChars (DEL) could hide a divi/* delimiter or an et_pb shortcode from the raw-input check. The shared DiviMarkup helper checks the raw and the normalized form and now guards every raw-content path: content-create/-update content and media-update description (attachment post_content). MediaImporter logs import failures with scheme, host, port and path only; uninstall.php lists the removed user meta.
