  "summary": "Fundación POS integrada sin duplicar pedidos ni inventario. Las migraciones 043–047 crean el modelo POS, añaden store_id al inventario, source/COMPLETED a órdenes, roles POS y el CHECK correcto para permitir walk-ins solo en source=pos. El error de build del admin se estabilizó fijando turbopack.root y verificando un build limpio.",

  "issues": [],
  "notes":"Migration 047 is intentionally a catch-up migration because 045 had already been applied before the user_id CHECK was identified. The previous invalid test ecommerce row was removed before applying the constraint; the real existing ecommerce order has a valid user_id."
