# 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)
