- Screen locker: disable VT switching (Ctrl+Alt+Fn) via setxkbmap srvrkeys:none on startup; restore on close (production mode only). Gracefully skips if setxkbmap is not installed (shutil.which). Tests: 7 new tests, 100% branch coverage maintained. - Midnight shutdown: restore real schedule values (Mon-Wed 21:00, Thu-Sun 22:00, morning end 05:00); re-enable the three commented-out leniency checks in check_schedule_protection(); self-lock script with chattr +i at end of enable_midnight_shutdown(). - Hosts install: add UNBLOCK_STATE_FILE tracking for whitelisted domains; check_unblock_entries_protection() blocks installation if the unblock list grows; save state after install; self-lock install.sh and generate_hosts_file.sh with chattr +i.
