# Migracion: Sistema de Rangos Maya v2.0 a v2.1

**Version:** 2.1.0
**Fecha:** 2025-12-18
**Autor:** Requirements-Analyst (SIMCO)
**Tipo:** Migracion de Datos y Logica

---

## RESUMEN EJECUTIVO

Migracion de umbrales de XP para hacer **todos los 5 rangos Maya alcanzables** con el contenido educativo actual (1,950 XP disponibles en Modulos 1-3).

### Problema Resuelto

Los umbrales v2.0 (hasta 10,000 XP para K'uk'ulkan) eran **inalcanzables** con el contenido educativo disponible, causando frustracion en estudiantes y falta de motivacion.

### Solucion Implementada

Reduccion de umbrales para que la progresion sea:
- **Justa:** Todos los rangos alcanzables completando M1-M3 con excelencia
- **Motivante:** Progresion visible y constante
- **Pedagogica:** Recompensas alineadas con esfuerzo real

\i apps/database/seeds/dev/gamification_system/03-maya_ranks.sql

-- O manualmente:
UPDATE gamification_system.maya_ranks SET
    min_xp_required = 0, max_xp_threshold = 499
WHERE rank_name = 'Ajaw';

UPDATE gamification_system.maya_ranks SET

## VERIFICACION

### Queries de Validacion

```sql
-- Verificar umbrales
SELECT rank_name, min_xp_required, max_xp_threshold, xp_multiplier
FROM gamification_system.maya_ranks
ORDER BY min_xp_required;

SELECT
    mr.rank_name,
    COUNT(us.user_id) as usuarios
FROM gamification_system.maya_ranks mr
LEFT JOIN gamification_system.user_stats us
    ON us.current_rank = mr.rank_name
GROUP BY mr.rank_name
ORDER BY mr.min_xp_required;

-- Verificar funcion de calculo
SELECT gamification_system.calculate_maya_rank_from_xp(0);    -- Ajaw
