+# F-137 — Design: Unify price/stock/EAN/meta save into "Guardar cambios"
+
+**Author:** architect (auto-design)
+**Date:** 2026-08-21
+**Stage:** design
+
+## Context (problem)
+
+`apps/admin/src/features/products/components/sections/PriceStockSection.tsx` currently mixes four save flows:
+
+| Field group | Save trigger | Persistence |
+|---|---|---|
+| Price (PVP, IVA, Coste, Oferta, Neto) | Click on `Guardar precio` button | `PUT /api/pricing/variants/:id` |
+| Stock | `blur` / `Enter` on input | `PUT /api/inventory/:id/stock` |
+| EAN | `blur` / `Enter` on input | `PATCH /api/products/:id/variants/:vid` |
+| Peso unitario, Compra mínima | `blur` / `Enter` on inputs | `PATCH /api/products/:id` |
+
+The operator's request is: **single save point**. All four groups must persist when the user clicks `Guardar cambios` in `ProductEditor.tsx`. The `Guardar precio` button goes away. Auto-save on `blur`/`Enter` goes away too — otherwise we have two save sources racing each other.
+
+## Constraints
+
+- C-1. `PriceStockSection` already loads its own data (`useEffect` on `productId`). Keep that.
+- C-2. `ProductEditor` owns the main `handleSave` and the dirty-check snapshot. Don't break the dirty indicator.
+- C-3. In **create** flow, when `productsApi.create` returns a new productId, `PriceStockSection` enters "loaded" state asynchronously. We need a save path that works whether the section has already loaded its variant or not.
+- C-4. No backend changes. All persistence is via existing endpoints.
+- C-5. UX: the user must see clear feedback when the main save fails (partial vs full failure).
+
+## Design
+
+### Decision: imperative ref API on PriceStockSection
+
+Lifting all state to `ProductEditor` would force a wider refactor (re-render storms, props drilling, loss of internal load effect). The cheaper, equally clean option is an **imperative handle**:
+
+```ts
+// PriceStockSection.tsx — exposed via forwardRef + useImperativeHandle
+export interface PriceStockHandle {
+  /** Save all dirty fields. Throws on failure; never partial-silently. */
+  saveAll(): Promise<{
+    price: boolean;
+    stock: boolean;
+    ean: boolean;
+    meta: boolean;
+  }>;
+}
+```
+
+`ProductEditor` calls `priceStockRef.current?.saveAll()` **after** `productsApi.create/update` succeeds. The handle:
+
+1. **Reuses the existing save functions** (`savePrice`, `saveStock`, `saveEan`, `saveProductMeta`) — no business logic duplication.
+2. **Fetches the variant id on demand** if `variant === null` (create flow: the section's `useEffect` may not have fired yet). It does this by calling `productsApi.getVariants(productId)` and grabbing `items[0].id`. Idempotent — if the section already loaded the variant, the call is skipped.
+3. **Returns a per-group success map** so `ProductEditor` can show a single "Cambios guardados" message even when one group failed (or fail loudly if any group failed).
+
+### UX changes in PriceStockSection
+
+- **Remove** the `Guardar precio` button (line ~345–350).
+- **Remove** `onBlur={saveStock}`, `onBlur={saveEan}`, `onBlur={saveProductMeta}`, and the matching `onKeyDown={Enter}` handlers on those inputs. State stays local; persistence happens via the main button.
+- **Remove** per-field `stockMsg` / `eanMsg` / `metaMsg` / `priceMsg` success flashes. They're meaningless now that save is centralized. Replace with a single `saveStatus` indicator rendered next to the section heading when the main save reports partial failure for that group.
+- **Add** a small "dirty" indicator inside the section heading so the user knows there are unsaved changes since the last main save (small dot or italic "sin guardar"). This is a quality-of-life addition — strictly optional, scope_in if cheap.
+
+### UX changes in ProductEditor
+
+- `handleSave` calls `priceStockRef.current?.saveAll()` after `productsApi.update/create` succeeds.
+- If `saveAll()` throws, set `error` with the failure summary. If it returns partial success, set `success` with a "guardado (algunos cambios no)" hint.
+- The `priceMsg` slot in `PriceStockSection` is now reserved for the **per-group failure message** so the user knows which field failed.
+
+### Sequencing in handleSave
+
+```ts
+const handleSave = async () => {
+  setSaving(true); setError(''); setSuccess('');
+  try {
+    // 1. Product payload (existing)
+    const saved: Product = isCreate
+      ? await productsApi.create(payload)
+      : await productsApi.update(productId, payload);
+    setProductId(saved.id);
+    if (isCreate) router.replace(`/products/${saved.id}`);
+
+    // 2. Optionally generate SEO with IA (existing branch — unchanged)
+    if (!hasMeaningfulContent(desc) || !seoTitle.trim() || !seoDesc.trim()) {
+      setGenerating(true);
+      try { saved = await productsApi.generateSeo(saved.id); /* ... */ }
+      finally { setGenerating(false); }
+    }
+
+    // 3. NEW: save price/stock/EAN/meta via the section handle
+    try {
+      const result = await priceStockRef.current?.saveAll();
+      const failed = Object.entries(result ?? {}).filter(([_, ok]) => !ok).map(([k]) => k);
+      if (failed.length) {
+        setSuccess(`Producto guardado. Revisa: ${failed.join(', ')}.`);
+      } else {
+        setSuccess(isCreate ? '¡Producto creado!' : 'Cambios guardados');
+      }
+    } catch (saveErr) {
+      setError(saveErr instanceof Error ? saveErr.message : 'Error al guardar precio/stock/EAN');
+    }
+
+    // 4. Existing snapshot + dirty reset
+    snapRef.current = getSnap();
+    dirtyRef.current = false;
+  } catch (err) {
+    setError(err instanceof Error ? err.message : 'Error al guardar');
+  } finally {
+    setSaving(false);
+  }
+};
+```
+
+### Edge cases
+
+- **Empty state on edit (variant is null)**: shouldn't happen — `PriceStockSection`'s load effect runs on mount. If it does (e.g., race), `saveAll` returns `{ price: false, stock: false, ean: false, meta: false }` with a clear error message.
+- **Pending state on create**: the section has all field state but no `variant`. `saveAll` does `productsApi.getVariants(productId)` once to obtain the variant id, then proceeds. Idempotent.
+- **Network failure mid-save**: the per-group try/catch in `saveAll` ensures one group's failure doesn't block the others. Aggregate error surfaced to the user.
+- **Dirty tracking**: the dirty snapshot in `ProductEditor` does NOT include price/stock/EAN/meta values (those live in `PriceStockSection`). To keep the dirty indicator honest, `PriceStockSection` should expose an `isDirty()` method too, OR the indicator just covers the product payload fields. Going with the latter: keep it simple, document the gap.
+
+### Files affected
+
+| File | Change |
+|---|---|
+| `apps/admin/src/features/products/components/sections/PriceStockSection.tsx` | forwardRef, useImperativeHandle, saveAll(), remove button, remove blur/Enter saves, remove per-field msg |
+| `apps/admin/src/features/products/components/ProductEditor.tsx` | priceStockRef, call saveAll() in handleSave, handle partial-failure message |
+
+### Out of scope
+
+- Backend changes (none).
+- Dirty indicator that covers price/stock/EAN/meta (separate ticket if the operator requests it).
+- Removing the inline success flash animations on the four input groups — already gone as part of the UX changes.
+
+## Acceptance criteria
+
+- AC-1. `Guardar precio` button is gone from the UI.
+- AC-2. Stock, EAN, peso, compra mínima inputs do NOT auto-save on blur or Enter.
+- AC-3. Clicking `Guardar cambios` persists price + stock + EAN + meta in a single logical action (multiple HTTP requests, same UX moment).
+- AC-4. Create flow: after `Crear producto`, the variant's price/stock/EAN/meta are also persisted. Verified end-to-end with a fresh product.
+- AC-5. If any of the four groups fails, the user sees which group(s) failed and the others are still saved.
+- AC-6. Build green, lint green, typecheck green.
+- AC-7. Existing dirty indicator (`Guardar cambios` becomes enabled/disabled) keeps working for the product payload.

+# F-137 — Implementer notes: Unify price/stock/EAN/meta save into "Guardar cambios"
+
+## Cambios
+
+### `apps/admin/src/features/products/components/sections/PriceStockSection.tsx`
+
+- Convertido de function declaration a `forwardRef<PriceStockHandle, { productId?: string }>`. El nuevo `PriceStockHandle` expone un único método `saveAll(): Promise<{price, stock, ean, meta}>`.
+- Eliminados los `useState` `savingPrice`, `savingStock`, `savingEan`, `savingProductMeta`. Los mensajes (`priceMsg`, `stockMsg`, `eanMsg`, `metaMsg`) ahora solo se setean en caso de error (sin flashes de éxito tipo `✓ Guardado`).
+- Las funciones `savePrice` / `saveStock` / `saveEan` / `saveProductMeta` ahora devuelven `Promise<boolean>` y propagan el mensaje de error en el state msg correspondiente. Reutilizan los mismos endpoints HTTP que antes — sin cambios de backend.
+- Nuevo helper `ensureVariant()`: si la sección aún no tiene `variant` en su state local (caso típico del flujo de creación, donde `productId` se setea pero el `useEffect` de carga aún no corrió), hace un `productsApi.getVariants(productId)` y guarda el primer item. Idempotente.
+- `useImperativeHandle` con deps array = state values (gross, net, cost, offer, vatRate, stock, ean, unitWeightGr, minPurchaseQty, taxRates). Esto garantiza que el handle siempre vea los valores más recientes del formulario.
+- `saveAll()` ejecuta los 4 saves con `Promise.all` y devuelve el mapa de éxito. No lanza excepción: cada grupo se maneja con su propio try/catch interno.
+- **Eliminado el botón "Guardar precio"** (líneas que iban a ser 392–399 del original).
+- **Eliminados `onBlur={saveX}` y `onKeyDown={Enter→saveX}`** en los inputs de stock, EAN, peso unitario y compra mínima. Los inputs ya no persisten automáticamente al perder el foco.
+- **Eliminados `disabled={savingX}`** en los inputs correspondientes (ya no hay estado de guardado).
+- Cambiado el render de los mensajes para que solo muestren texto rojo (sin el `text-green-600` para `✓`).
+- Sin cambios en la lógica de cálculo IVA/PVP/Neto (las funciones `onGrossChange`, `onNetChange`, `onVatChange` siguen iguales).
+- Sin cambios en la carga inicial de datos (el `useEffect` que llama `productsApi.get` / `getVariants` / `pricingApi.getVariantPrice` / `inventoryApi.getAvailability` sigue intacto).
+
+### `apps/admin/src/features/products/components/ProductEditor.tsx`
+
+- Añadido import del tipo: `import { PriceStockSection, type PriceStockHandle } from './sections/PriceStockSection';`.
+- Añadido `priceStockRef = useRef<PriceStockHandle>(null)` junto al state de marcas/categorías.
+- `<PriceStockSection ref={priceStockRef} productId={productId} />` en la pestaña General.
+- `handleSave`:
+  - Después del bloque de generación SEO, llama `priceStockRef.current?.saveAll()` dentro de su propio try/catch.
+  - Si `saveAll` reporta fallos parciales (algún grupo `ok: false`), se calcula la lista de grupos fallidos y se muestra un mensaje tipo `Producto guardado. Revisa precio, EAN.` mapeando cada clave a su etiqueta en español.
+  - Si todo va bien, mensaje estándar (`¡Producto creado!` / `Cambios guardados`).
+  - Si `saveAll` lanza una excepción (caso muy improbable, sería bug), se setea `error`.
+  - Refactor menor: el `setSuccess` ya no se setea en la rama de generación de IA si el producto tenía contenido incompleto (porque ahora se sobreescribe con el resultado del `saveAll`). El mensaje final siempre refleja el estado combinado.
+
+## UX
+
+Antes:
+- Precio → botón "Guardar precio"
+- Stock, EAN, peso, compra mínima → auto-save en blur o Enter (con ✓ verde durante 3s)
+
+Ahora:
+- Todos los campos persisten al pulsar "Guardar cambios" en la cabecera del editor.
+- Los inputs son "tontos": solo mantienen estado local; no hacen red al perder foco.
+- Si el guardado central falla parcialmente, se muestra qué grupo falló (`precio`, `stock`, `EAN`, `peso/compra mínima`) en el banner verde de éxito (con coletilla "Revisa X").
+- Si todo va bien, banner verde estándar.
+
+## Archivos modificados
+
+- `project/apps/admin/src/features/products/components/sections/PriceStockSection.tsx`
+- `project/apps/admin/src/features/products/components/ProductEditor.tsx`
+
+## Evidencia
+
+```
+$ cd project/apps/admin && npx tsc --noEmit
+(exit 0)
+
+$ npx eslint src/features/products/components/sections/PriceStockSection.tsx \
+              src/features/products/components/ProductEditor.tsx
+✖ 7 problems (0 errors, 7 warnings)
+  - 6 warnings pre-existentes sobre `as any` en ProductEditor.tsx
+  - 1 warning pre-existente sobre unused eslint-disable
+
+$ npm run build
+✓ Compiled successfully
+```
+
+## Notas
+
+- En el flujo de creación, `saveAll` debe ejecutarse después de que `productId` esté seteado (porque `PriceStockSection` necesita un productId para resolver la variante). Como `handleSave` hace `setProductId(saved.id)` justo después de `productsApi.create`, y `saveAll` se invoca en el siguiente tick de microtask, el ref está disponible. El helper `ensureVariant` cubre el caso race donde el `useEffect` de carga aún no haya disparado.
+- No hay tests automatizados para esta vista. La verificación end-to-end requiere navegador: crear un producto nuevo con PVP + stock + EAN + peso, pulsar "Crear producto", recargar `/products/:id`, comprobar que los valores se mantienen.
+- El build regenerado queda en `apps/admin/.next/`. El operador debe reiniciar el monolito (`./scripts/monolith.sh prod restart`) para que el bundle actualizado se sirva en `:3004`.
