+# F-100 — Arquitectura: generación automática de SKU a partir del título
+
+## Estado actual
+- En `POST /products` (catálogo) se crea una variante por defecto con `sku = "SKU-MV-${productId}"`.
+- El admin no expone la edición del SKU en `PriceStockSection` (sólo EAN, precios, stock).
+- No hay endpoint de "sugerir SKU" en el backend.
+
+## Decisiones
+1. **Helper puro** `src/modules/catalog/domain/sku.ts`:
+   - `generateSkuFromTitle(title)`: normaliza el título (mayúsculas, sin diacríticos, sin caracteres no alfanuméricos, guiones separadores, recorte a 100 chars). Devuelve `MV-<SLUG>`.
+   - `uniqueSku(base, existing: Set<string>)`: si el base está ocupado, prueba `base-2`, `base-3`, … hasta encontrar uno libre.
+2. **Backend**:
+   - Cambiar la creación de producto para usar el SKU derivado del título en lugar del UUID; mantener `uniqueSku` para resolver colisiones.
+   - Endpoint nuevo `POST /admin/products/sku:generate` con body `{ title: string }` → `{ sku: string }`. Útil para preview antes de crear.
+   - Permitir que el admin edite el SKU en la sección "Precios y Stock" (PriceStockSection). Persistencia vía `PATCH /products/:id/variants/:variantId`.
+3. **Admin UI** (`apps/admin`):
+   - `api-client.ts`: `productsApi.generateSku(title)` y `productsApi.updateVariant(id, vid, { sku })`.
+   - Sección "Precios y Stock": muestra el SKU actual como input editable con botón "Regenerar" que llama al endpoint.
+   - Página de creación de producto: llama a `generateSku` al blur del nombre para previsualizar el SKU.
+4. **Validación**:
+   - SKU: `^[A-Za-z0-9-]+$`, 1..100 chars (alineado con `newVariantSchema`).
+   - El endpoint `/admin/products/sku:generate` sólo da sugerencias; el cliente decide.
+   - Duplicados: PostgreSQL ya rechaza por `UNIQUE` en `product_variants.sku`. Aclarar el error al admin con un mensaje claro.
+
+## Tests
+- `sku.test.ts` (6-8): normalización, acentos, longitudes, collision in `uniqueSku`.
+- Añadir test al repositorio Variantes (e2e) si el repo expone `findBySku`: comprobar que se devuelve un SKU existente para validar.
+
+## Fuera de alcance
+- Sin servicio externo de SKU.
+- Sin relajar la unicidad.
+- Sin afectar a las variantes ya creadas (migración no requerida).

+# F-100 — Generación automática de SKU desde el título
+
+## Backend
+- `src/modules/catalog/domain/sku.ts` (helper puro):
+  - `generateSkuFromTitle(title)`: normaliza mayúsculas, diacríticos, separadores; produce `MV-<SLUG>` (max 100 chars).
+  - `uniqueSku(base, existing)`: añade `-2`, `-3`, … hasta encontrar uno libre; truncando a 100 chars.
+- `src/modules/catalog/tests/sku.test.ts` (9 tests): normalización, acentos, `&`, hyphens, longitud, mayúsculas, lowercase collisions, truncado.
+- `src/modules/catalog/domain/ports.ts` + `pg-variant-repository.ts`: nuevo `listAllSkus()` para reutilizar en la creación.
+- `src/modules/catalog/api/catalog.routes.ts`:
+  - `POST /products/sku:generate` (admin): recibe `{ title }` y devuelve `{ sku }` único.
+  - `POST /products`: la variante por defecto ahora se crea con `generateSkuFromTitle(product.name)` + `uniqueSku` en vez de `SKU-MV-${uuid}`.
+  - `GET /products/:id/variants` (lazy migration): igualmente usa SKU derivado del título.
+
+## Admin UI (apps/admin)
+- `lib/api-client.ts`: `productsApi.generateSku(title)`.
+- `features/products/components/sections/PriceStockSection.tsx`:
+  - Nuevo bloque "SKU" con input editable (validación `^[A-Za-z0-9-]+$`), botón `↻` para regenerar sugerencia.
+  - Guardado en blur/Enter; mensajes: `✓` / `SKU duplicado` / `SKU inválido`.
+
+## Evidencia
+- `npm run typecheck` (backend) OK.
+- `npm test`: 169 passed / 0 failed (9 nuevos).
+- `apps/admin tsc --noEmit` OK.
+- Smoke: `POST /products/sku:generate { "title": "Aceite de Oliva Virgen Extra" }` → `{ "sku": "MV-ACEITE-DE-OLIVA-VIRGEN-EXTRA" }`.
