  "summary": "Acceptance criteria traced to evidence; full suite and type checks green.",
  "acceptance_traceability": [
    { "criterion": "Creating a variant suggests a title-derived SKU", "evidence": "POST /products now derives SKU from product.name via generateSkuFromTitle; POST /products/sku:generate exposes the same for previews", "ok": true },
    { "criterion": "Generated SKU is normalized and remains editable", "evidence": "SKU is uppercase, ASCII-only, hyphen-separated, max 100 chars; admin UI shows it as an editable input saved via PATCH /products/:id/variants/:variantId", "ok": true },
    { "criterion": "Duplicate SKU is rejected clearly", "evidence": "uniqueSku resolves collisions; PG UNIQUE constraint is the source of truth; the route maps the duplicate error to ProductVariantCodeAlreadyExistsError (409) and the admin UI shows 'SKU duplicado'", "ok": true },
    { "criterion": "Typecheck, tests, verify pass", "evidence": "npm run typecheck OK; npm test 169 passed / 0 failed (9 new); admin tsc --noEmit OK; npm run build (backend) OK", "ok": true }
