The stock TinyCore kernel config has "# CONFIG_SECURITY is not set" which caused make olddefconfig to silently revert all security configs in a single pass. Fix by applying security configs (AppArmor, Audit, LSM) after the first olddefconfig resolves base dependencies, then running a second pass. Added mandatory verification that exits on missing critical configs. All QEMU test scripts converted from broken -cdrom + -append pattern to direct kernel boot (-kernel + -initrd) via shared test/lib/qemu-helpers.sh helper library. The -append flag only works with -kernel, not -cdrom. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
