void handle_ucp_webhook(const HttpRequest& request) {
// Verify signer profile, RFC 9421 signature, digest, freshness,
// key rotation, and replay state before publishing.
auto order = verify_ucp_request(request);
auto identity = lookup_buyer_identity(order.checkout_id);
axllm::AxEventEnvelope event;
event.id = order.id;
event.source = "ucp://orders";
event.type = "ucp.order.fulfilled";
event.data = order.data;
runtime.publish(event, identity, "authenticated");
