+# TPV-FIXES — Bug 400 Fix (pos/sales)
+
+## Problema
+Error 400 en `/api/pos/sales` cuando se intenta dejar un ticket pendiente nuevamente después de recuperarlo.
+
+## Causa Raíz
+Cuando se recuperan items de una venta pendiente (`listOrderItems`), el endpoint **no devuelve** `variantId` ni `productId`. El código de recuperación pone `variantId: null`.
+
+Cuando se intentaba crear una nueva venta con esos items, el backend Zod validaba que `variantId` sea UUID válido para items de tipo `stock`, causando 400.
+
+## Solución
+En todos los lugares donde se envía `createSale`, convertir items sin `variantId` a **free items** (no requieren variantId).
+
+### Archivos Modificados
+`project/apps/pos/src/app/(terminal)/page.tsx`:
+
+1. **`doCheckout`** (checkout con pago): Convierte items sin `variantId` a free items
+2. **`doParkSale`** (aparcar sin/com con nombre): Convierte items sin `variantId` a free items
+3. **`parkAndRecover`** (aparcar y recuperar): Convierte items sin `variantId` a free items
+
+### Código Común Agregado
+```typescript
+// TPV-FIXES: items without variantId (recovered sales) must be sent as free items
+const saleItems = cart.map((item) => {
+  if (item.kind === 'free' || !item.variantId) {
+    return {
+      kind: 'free' as const,
+      name: item.name,
+      unitPriceCents: item.unitPriceCents,
+      quantity: item.quantity,
+    };
+  }
+  return {
+    kind: 'stock' as const,
+    variantId: item.variantId,
+    quantity: item.quantity,
+    discountCents: item.discountCents,
+  };
+});
+```
+
+## Testing
+1. Recuperar una venta pendiente sin items en carrito → pagar → debe funcionar
+2. Recuperar una venta pendiente CON items en carrito → "Dejar actual pendiente y recuperar" → debe funcionar
+3. Crear carrito sin cliente → aparcar sin nombre → debe funcionar
