-- Script: Validate Seeds Integrity
-- Description: Valida integridad referencial de todos los seeds
-- Created: 2025-11-15
-- Version: 1.0
-- =====================================================
--
-- PROPÓSITO:
-- Este script verifica que:
-- 1. No haya registros huérfanos (FK rotas)
-- 2. Conteos de registros coincidan (users = profiles = user_stats)
-- 3. Triggers funcionaron correctamente
-- 4. Seeds sociales tienen datos suficientes
--
-- EJECUCIÓN:
-- psql -U gamilit_user -d gamilit_platform -f validate-seeds-integrity.sql
-- =====================================================
