- Protected apt repository writes across modules/repos.sh by adding `|| return 1` to `_write_deb822()` and `_write_classic()`, ensuring script continuation on failure instead of aborting under set -e. - Added idempotent backup restoration in restore_previous_repos() with `sudo cp ... || true` and `sudo rm ... || true` to prevent fatal errors during repository recovery operations. - Implemented rollback mechanism in migrate_to_branch() by wrapping _write_branch_sources() in a conditional check, restoring backup on failure and returning error code 1. - Hardened firmware installation flow in modules/firmware.sh with `|| true` guards on all apt commands (broadcom-sta-dkms, network firmware packages, backports/stable paths), preventing set -e aborts during package management. - Secured modprobe operations by adding `|| true` to wl module loading and blacklist file writes, ensuring wireless driver installation proceeds even if kernel module operations fail. - Added GPU tools installation protection in _helpers.sh with `|| true` guard on vainfo command execution after nvtop installation completes successfully. - Fixed NVIDIA Wayland configuration in modules/gpu/nvidia.sh by adding `|| return 1` to nvidia-wayland.conf tee operation, preventing silent failures when writing modprobe configuration files. - Implemented network warning notification before Broadcom wireless module removal to alert users of potential SSH disconnection during WiFi driver transitions. - Added broadcom blacklist file protection with `|| true` guard on modprobe.d/blacklist-broadcom.conf writes to prevent script termination on filesystem errors. - Standardized error handling patterns across all firmware and GPU modules, replacing direct command execution with conditional wrappers that maintain script continuity under failure conditions.
