Bien, tengo todo el contexto. Analicé el código legacy. Aquí van los problemas identificados y la propuesta migrada:

Problemas encontrados en el código original
PHP (críticos):

mysql_query() / mysql_fetch_array() → funciones eliminadas en PHP 7+
Variables SQL interpoladas directamente → riesgo de SQL injection
<html>/<head>/<body> presentes → no debe tenerlas (es fragmento AJAX)
Scripts de editor incluidos en el fragmento (nicEdit, ckeditor) → deben cargarse en la página principal
$grado y $grupo usados en el else sin estar definidos
date("y-m-d") → año con 2 dígitos, debería ser "Y-m-d"

Diseño: interfaz con tablas HTML para layout, estilos inline, sin consistencia visual con el resto del sistema.

Código migrado
