+# F-094 — Implementer evidence
+
+## Changes
+
+- Added `VariantManager` to the Publish tab with a plain-language explanation of variants, SKU, and EAN.
+- Added SKU-required/EAN-optional variant creation using the existing `POST /products/:id/variants` API.
+- Added existing variant list and inline success/conflict feedback.
+- Added `productsApi.createVariant`.
+- Updated Pricing and Inventory empty states to point to the now-existing Publish workflow.
+
+## Validation
+
+- Admin `npx tsc --noEmit` → exit 0
+- Admin ESLint on touched files → 0 errors (pre-existing warnings only)

 ## Incidencia actual (2026-08-20)
 
-La búsqueda de Inventario envía `q`, pero el listado admin solo filtra por nombre de producto. F-093 añade coincidencias por EAN de variante y actualiza el placeholder a EAN o nombre.
+Precios e Inventario indican que las variantes se crean desde Publicar, pero Publicar no ofrece creación ni explicación. F-094 añade la gestión de variantes allí.
+
+## Última incidencia resuelta (2026-08-20)
+
+F-093 cerrada con todos los gates aprobados. Inventario busca ahora por EAN o nombre de producto.
+
+## Incidencia anterior (2026-08-20)
+
+La búsqueda de Inventario enviaba `q`, pero el listado admin solo filtraba por nombre de producto.
