+# F-070 — Implementer evidence
+
+## Problem
+
+Product attributes (bio, vegano, sin-gluten, etc.) are returned by the backend
+`serializeProduct` (already includes `attributes: product.attributes`) but the
+frontend `Product` type omits the field and the product detail page never
+renders them. Customers see no attribute badges on `/products/[slug]`.
+
+## Root cause
+
+1. `project/frontend/src/types/api.ts` — `Product` interface missing `attributes` field.
+2. `project/frontend/src/app/products/[slug]/page.tsx` — no attributes rendering section.
+
+Backend already ships `PRODUCT_ATTRIBUTES` enum (16 values) in
+`project/src/modules/catalog/domain/product.ts` and `serializeProduct`
+returns the array. No backend changes needed.
+
+## Changes
+
+### Type definition
+`project/frontend/src/types/api.ts`
+
+- Added `PRODUCT_ATTRIBUTES` const array (16 values matching backend).
+- Added `ProductAttribute` type = `(typeof PRODUCT_ATTRIBUTES)[number]`.
+- Added `attributes?: ProductAttribute[]` to the `Product` interface.
+
+### Attribute labels
+`project/frontend/src/lib/product-attributes.ts` (new)
+
+- `ATTRIBUTE_LABELS: Record<ProductAttribute, string>` — Spanish human-readable
+  labels for each attribute slug (bio → "Eco", vegano → "Vegano", etc.).
+- `getAttributeLabel(attr)` helper with fallback to raw slug.
+
+### Badge component
+`project/frontend/src/components/product/ProductAttributes.tsx` (new)
+
+- Renders attributes as `inline-flex` rounded-full badges with emerald styling.
+- Returns `null` when no attributes (no DOM noise).
+- Accessible: `title` attribute on each badge = full label.
+
+### Page integration
+`project/frontend/src/app/products/[slug]/page.tsx`
+
+- Import `ProductAttributes`.
+- Render `<ProductAttributes attributes={product.attributes} />` right after
+  the product `<h1>` title, before the price section.
+
+## Build verification
+
+- `npx tsc --noEmit` (frontend) — exit 0
+- `npx eslint` on all 4 changed files — exit 0
+- `./scripts/verify.sh` — exit 0
+
+## Files touched
+
+```
+project/frontend/src/types/api.ts                                           (modified — added ProductAttribute type + attributes field)
+project/frontend/src/lib/product-attributes.ts                              (new — attribute label map + helper)
+project/frontend/src/components/product/ProductAttributes.tsx               (new — badge component)
+project/frontend/src/app/products/[slug]/page.tsx                           (modified — render badges after title)
+```
+
+## Acceptance traceability
+
+| Acceptance criterion | How it is met |
+| -------------------- | ------------- |
+| Product detail page renders product attributes as badges | `ProductAttributes` component renders `ATTRIBUTE_LABELS[attr]` as emerald badges on `page.tsx` |
+| No regression on existing product pages | `attributes` is optional (`?`); pages without attributes render `null` — no layout change |
+| `verify.sh` is green | Exit 0 |
