  "verdict": "APPROVED",
  "summary": "No security boundary touched. Items already validated server-side: route handler enforces isUuid on productId/variantId and integer 1..99 on quantity. Client-side mapping trusts no untrusted field — productId/variantId/quantity come from CartContext which is populated from the store catalog. No new auth surface.",
  "evidence": [
    "Items forwarded are productId, variantId and quantity — same fields the route already validates via isUuid and parseQuantity",
    "No new HTTP endpoints, no new cookies, no new headers, no new env vars",
    "No user-controlled strings are rendered server-side (only IDs)",
    "git diff shows zero changes outside project/frontend/src/components/checkout/CheckoutClient.tsx"
