- Fixed command injection in desktop_display.sh by converting word-splitting loops to safe array-based iteration for LightDM/GDM3 configuration and XFCE package installation. - Added symlink detection guard before repository file operations in repos.sh to prevent TOCTOU attacks during restore_previous_repos(). - Hardened SUDO_USER resolution with awk validation against /etc/passwd to prevent root fallback and ensure real login users are targeted for sudoers configuration. - Implemented algorithm (lz4/zstd) and size validation before ZRAM configuration writes in zram.sh to reject invalid inputs. - Protected grep MemTotal read from /proc/meminfo with 2>/dev/null and default assignment under set -u. - Added || true guards around apt-cache madison pipelines in firmware.sh, kernel.sh, gpu.sh, and utils.sh to prevent pipefail aborts when backports unavailable. - Wrapped whiptail installation in if/else blocks to allow offline error messages instead of script termination under set -e. - Fixed grep -c output duplication in swap.sh with proper || true pattern and default variable assignment. - Replaced unquoted $cleaned loops with array conversion using while read for secure package iteration across gaming, desktop_display, firmware, and kernel modules. - Anchored sed regex patterns to space-delimited "main" components to prevent mirror URL corruption in sources.list editing. - Escaped % characters in _msg() function before passing to whiptail to prevent printf format interpretation crashes. - Consolidated package version helpers into canonical wrappers: _get_pkg_version, _get_installed_version, _get_backports_version for consistent apt/dpkg queries. - Created _install_if_missing() and _install_pkg() with proper error handling that respects set -e while providing user feedback on installation failures. - Removed 6 dead code functions (~51 lines): check_system_time, sync_system_time, get_cpu_summary, get_ram_summary, pkg_versions, get_backports_kernel_version. - Added detect_displayserver and detect_audio_server to refresh_system_state() for complete state refresh when returning from menus. - Enhanced _on_interrupt() trap handler to kill lingering apt/dpkg child processes and clean /tmp/debianito.* temporary files on Ctrl+C or TERM. - Improved restore_previous_repos() with manifest-based backup verification (.backed_up_* markers) to prevent destructive repository file deletion. - Added mktemp usage for secure temporary deb file downloads in nvidia.sh, heroic.sh, and tools.sh to eliminate TOCTOU vulnerabilities in /tmp. - Fixed Bluetooth USB dongle misclassification as WiFi devices by excluding "bluetooth" strings from USB_WIFI_DEVS detection in firmware.sh. - Properly utilized the need array for selective package installation in internet.sh instead of hardcoding full package list. - Corrected fwupdmgr duplicate execution and grep false positives in system.sh with strict pattern matching for available updates. - update docs and added quickstart guide
