+-- Migration 001 — Disable RLS for academic project
+-- Fecha: 2026-05-16
+--
+-- Contexto: DailyMath es proyecto de universidad. No requiere
+-- aislamiento por usuario a nivel de fila. RLS solo agregaba
+-- fricción para tests automatizados sin aportar valor a la rúbrica.
+--
+-- ⚠️ Esta migración hace TODAS las tablas accesibles para
+-- lectura/escritura/borrado a cualquiera con la anon key del
+-- proyecto. Aceptable solo en contexto académico (no público).
+--
+-- Ejecutar en: Supabase Dashboard → SQL Editor → Run.
+-- Es idempotente (`if exists`), se puede correr varias veces.
