Security hardening: bind kubeconfig server to localhost, mount hardening (noexec/nosuid/nodev on tmpfs), sysctl network hardening, kernel module loading lock after boot, SHA256 checksum verification for downloads, kernel AppArmor + Audit support, complain-mode AppArmor profiles for containerd and kubelet, and security integration test. ARM64 Raspberry Pi support: piCore64 base extraction, RPi kernel build from raspberrypi/linux fork, RPi firmware fetch, SD card image with 4- partition GPT and tryboot A/B mechanism, BootEnv Go interface abstracting GRUB vs RPi boot environments, architecture-aware build scripts, QEMU aarch64 dev VM and boot test.
