  "summary": "Attributes are now typed and rendered as badges on the frontend product detail page. The backend already returns attributes via serializeProduct; the frontend Product type now includes attributes?: ProductAttribute[] and the page renders them via the ProductAttributes component. Type-safety verified: ATTRIBUTE_LABELS is a complete Record<ProductAttribute, string> covering all 16 backend enum values. No-regression: attributes is optional, component returns null when empty, existing pages without attributes are unaffected. Typecheck, lint, and verify.sh all pass.",
  "evidence": [
    "AC1 'Product detail page renders product attributes as badges' — ProductAttributes component renders emerald rounded-full badges from product.attributes after the h1 title; each badge has accessible title and visible label",
    "AC2 'No regression on existing product pages' — attributes field is optional (?); ProductAttributes returns null when undefined or empty array; product pages without attributes have identical layout to before; typecheck green",
    "AC3 'verify.sh is green' — exit 0",
    "Type completeness: ATTRIBUTE_LABELS is Record<ProductAttribute, string> — TypeScript would error if any of the 16 backend PRODUCT_ATTRIBUTES values lacks a label (no error → complete coverage)",
    "Backend: serializeProduct already returns attributes: product.attributes (verified in catalog.routes.ts:649) — no backend changes needed",
    "Frontend typecheck: npx tsc --noEmit — exit 0",
    "Frontend lint: npx eslint on all 4 changed files — exit 0"
