+# DASH-REMOVE-VARIANTS-CARD — Implementer evidence
+
+> Implementer: build · Estado: ready for review
+
+## Resumen ejecutivo
+
+He eliminado las 2 KPI cards del dashboard que referenciaban el concepto
+"variantes" de producto. El concepto variants ya no aplica desde F-108
+(remove variants module), y la card "Alertas" era además redundante con
+la campanita `OrderNotifications` (NOTIF-INVENTORY-ALERTS cerrado en la
+sesión anterior, que ahora muestra todas las alertas de inventario).
+
+## Cambios aplicados
+
+| Archivo | Δ | Descripción |
+|---|---|---|
+| `project/apps/admin/src/app/(dashboard)/page.tsx` | -19/+2 | Eliminada la KPI card "Sin stock" (sub "Variantes agotadas") de la fila primaria. Eliminada la KPI card "Alertas" (sub "X sin stock") de la fila secundaria. Grids rebalanceados: primaria `lg:grid-cols-4` → `lg:grid-cols-3`; secundaria `lg:grid-cols-3` → `lg:grid-cols-2`. |
+
+Total: 1 archivo, 2 líneas añadidas, 19 líneas eliminadas.
+
+## Estado final del dashboard
+
+| Fila | Antes | Después |
+|---|---|---|
+| KPI primaria | Pedidos hoy, Ingresos hoy, Productos activos, **Sin stock** | Pedidos hoy, Ingresos hoy, Productos activos |
+| KPI secundaria | Clientes nuevos, Total pedidos, **Alertas** | Clientes nuevos, Total pedidos |
+| Pedidos por estado | (intacto) | (intacto) |
+| Acciones rápidas | (intacto) | (intacto) |
+
+## Decisiones
+
+1. **`outOfStockVariants` en el interface Stats se mantiene.** Aunque ya no
+   se renderiza, sigue siendo parte del contrato con el backend. El
+   endpoint `/api/admin/stats` sigue devolviéndolo (otros consumers pueden
+   usarlo). Eliminarlo del interface sería un cambio de contrato de API
+   innecesario para un chore visual.
+2. **No reemplazo el card con algo nuevo.** El operador tiene la campanita
+   en el header que ahora muestra todas las alertas de inventario (low
+   stock, out of stock, caducados, por caducar, margen <30%). Duplicar
+   esa info en el dashboard sería ruido.
+3. **Backend intacto.** No se toca `/api/admin/stats` ni
+   `admin-stats/api/stats.routes.ts`. Si en el futuro nadie consume
+   `outOfStockVariants`, se limpiará en otra iteración.
+
+## Evidencia de verificación
+
+### 1. Typecheck admin
+
+```bash
+$ cd project/apps/admin && npx tsc --noEmit
+(exit 0, sin output)
+```
+
+### 2. verify.sh del orquestra
+
+```bash
+$ ./scripts/verify.sh
+[OK] backlog válido (367 features)
+[OK] runtime-status válido
+[OK] Orquestra verificado. Puedes trabajar.
+```
+
+### 3. Diff resumido
+
+```text
+project/apps/admin/src/app/(dashboard)/page.tsx | 21 ++-------------------
+1 file changed, 2 insertions(+), 19 deletions(-)
+```
+
+Cambios:
+- `lg:grid-cols-4` → `lg:grid-cols-3` (primaria).
+- `lg:grid-cols-3` → `lg:grid-cols-2` (secundaria).
+- Bloque `<KPICard label="Sin stock" .../>` eliminado.
+- Bloque `<KPICard label="Alertas" .../>` eliminado.
+
+## Cosas que NO hice (scope deliberado)
+
+- No toqué el backend `/api/admin/stats` (mantiene `outOfStockVariants`).
+- No reemplacé los cards eliminados con otros (campanita cubre el caso).
+- No eliminé `outOfStockVariants` del interface `Stats` (cambio de contrato innecesario).
+
+## Próximo stage
+
+→ **review_gate (reviewer)**: revisión técnica rápida.
+→ **security_gate (security)**: trivially OK (solo UI removal, sin superficie de seguridad).
+→ **qa_gate (qa)**: visual check.

+- Entregable: 2 KPI cards eliminadas del dashboard que referenciaban el concepto "variantes" (ya retirado desde F-108). Card "Sin stock" (sub "Variantes agotadas") en fila primaria. Card "Alertas" (sub "X sin stock" / "Revisar inventario") en fila secundaria. Grids rebalanceados: primaria 4→3 columnas, secundaria 3→2 columnas.
+- Decisiones: no se reemplaza con otro card porque la campanita `OrderNotifications` (NOTIF-INVENTORY-ALERTS cerrado antes en esta sesión) ya muestra todas las alertas de inventario. No se toca backend: `outOfStockVariants` sigue en la respuesta de `/api/admin/stats` (mantener contrato API).
+- Cobertura: 1 archivo, 2 líneas añadidas, 19 eliminadas. Cero impacto en superficie de seguridad (reducción ligera al eliminar 2 hrefs).
+- Artefactos: work/artifacts/DASH-REMOVE-VARIANTS-CARD/ (implementer.md, reviewer.json, security.json, qa.json, leader-close.json). Sin architect.md (design stage opcional, chore trivial).
