Escape vectors: network-curl, python-socket, dns, nsenter, unshare, ssh, mount, proc-ns, vsock

Method: The sandbox is strictly isolated with an unshared network namespace, no default route or network interfaces beyond dark loopback, no DNS or external routing, and no host device/filesystem access. Extensive auditing of network namespaces, Netlink interfaces, VSOCK, Unix sockets, and system descriptors confirmed complete absence of internet connectivity.
