  "verdict": "APPROVED",
  "summary": "No new attack surface. The frontend proxy forwards the original cookie; the existing backend endpoint keeps the owner-or-admin guard. The checkout override path doesn't write anything back to the customer's address book (the user only picks, never edits).",
  "evidence": [
    "Frontend /api/users/[id]/addresses forwards the request with the original cookie; backend's requireOwnerOrAdmin still applies",
    "Checkout manual edits to the form are scoped to the order payload — no backend write",
    "No new endpoints, no new env vars, no new dependencies",
    "Existing auth/me + cart cookie contracts unchanged"
