(SYS_ADMIN, MKNOD, NET_ADMIN, SYS_CHROOT, SETFCAP) (C-03)
- run.sh: Restrict SB key directory to mode 700 and key files
to mode 600 (C-04)

with enforce_for_root (M-03)
- security-hardening.sh: Initialize AIDE database and create daily
cron job for integrity checks (M-06)
- sudo-hardening.sh: Use atomic install -m 600 instead of touch+chmod
to avoid race condition (L-07)
- preseed.cfg: Disable direct root login (L-01)
- run.sh: Comment explaining KNEL_BUILD_MODE cannot be env-spoofed
since it's set from command argument (L-05)

fix: resolve critical build bugs and add missing PRD requirements
...
Critical fixes:
- Fix security-hardening.sh live hook: removed broken source from
/build/src/ which doesn't exist during live-build; made hook
self-contained by inlining all config generation
- Fix firewall-setup.sh live hook: removed broken source from
/build/src/; hook already had inline nftables config
- Fix install-scripts.sh: replaced /workspace/src/ references with
embedded inline scripts (installed system has no /workspace)
- Fix UKI cmdline in standalone uki_build(): added
lockdown=confidentiality and module.sig_enforce=1 to match the
inline Secure Boot hook
- Fix WiFi blacklist: expanded from 6 entries to 19, now covers all
PRD FR-005 driver families (rtl*, iwl*, ath*, brcm*, mwifi*, rt2*)
Missing PRD requirements added:
- kernel-hardening.sh (FR-007): sysctl parameters for ASLR, ptrace
restriction, kptr_restrict, dmesg_restrict, kexec disabled, SUID
dumpable disabled, hardlink/symlink protection, network hardening
- service-hardening.sh (FR-007): disables and masks avahi-daemon,
cups, bluetooth, NetworkManager, ModemManager, whoopsie, apport
- sudo-hardening.sh (FR-007): requiretty, logging (input/output),
timestamp timeout, env_reset, restricted football user commands
- mount-hardening.sh (FR-007): nodev/nosuid/noexec on /tmp,
nodev/nosuid on /home, /dev/shm hardening
Test improvements:
- Rewrote security-hardening_comprehensive_test.bats: tests now
source scripts, call functions, and verify generated output files
- Rewrote firewall-setup_comprehensive_test.bats: tests now create
WireGuard configs, call parse_wg_endpoint, verify nftables output
- Added new-hooks_test.bats: 42 tests for kernel hardening, service
hardening, sudo hardening, mount hardening, self-containment
verification, and WiFi blacklist completeness
- Total: 788 tests passing, 0 failures, 0 shellcheck warnings
