- Verified the repository backup rc in migrate.sh. `_persistent_backup_repos()` now aborts before any destructive step when the tar archive is missing or corrupt, removing the invalid backup itself.
- Verified the restore rc in migrate.sh. `_restore_backup()` now reports failure instead of printing a green "Backup restored" message, and its caller distinguishes a restored backup from a failed restore.
- Made the upgrade phases fail honestly. `apt upgrade` and `apt full-upgrade` now abort with `apt --fix-broken install` + `dpkg --configure -a` instructions instead of reporting "completed successfully" over a partially-upgraded system.
- Made repository source writes atomic. Both writers tee into a `.tmp` file and move into place, and the `/etc/apt/sources.list` removal now happens after the write.
- Corrected the SID warning text in migrate.sh to reflect that security fixes arrive via package uploads rather than a nonexistent sid-security suite.
- Added exit-path cleanup traps for the temp `.deb` files: `trap 'rm -f "$deb_path"' RETURN` in `heroic.sh`and `tools.sh`.
- Tightened Heroic download handling: the API fetch uses `curl -fsS --connect-timeout 10 --max-time 30`, the download uses `curl -fsSL --max-time 300`, and the `.deb` is validated with both `dpkg-deb --info` and `dpkg-deb --contents`; `sudo apt install` is guarded with `if !` before the temporary file is deleted.
- Tightened the OpenRGB install path: the Codeberg API fetch uses `curl -fsS --connect-timeout 10 --max-time 30` and the download `curl -fsSL --max-time 300`, with the same dual `dpkg-deb` integrity check as the Heroic fallback.
- Guarded the OpenRGB post-install side effects: the script now aborts after removing the failed `.deb` if `sudo apt install` returns non-zero, so `modprobe i2c-dev`, `/etc/modules`, the `i2c` group membership, `udevadm`, and the `setcap` step no longer run when the package is absent.
- Enhanced repository detection logic in `modules/repos/repo_detect.sh`. Implemented `has_active_deb_sources()` for content-aware scanning across `sources.list`, `*.list`, and `*.sources` files. Empty or comment-only files are now correctly identified as "none" to trigger bootstrapping.
- Enforced Debian 13 (Trixie) specific logic in `detect_repo_format()`. Deb822 format is only applied when `debian.sources` is active; Bookworm and Bullseye systems default strictly to classic sources.list regardless of file presence.
- Added state guard against mixed configuration formats (deb822 + classic active simultaneously) with a warning prompt before writing, preventing duplicate entries in `/etc/apt/sources.list`.
- Rewrote `_repos_enable_components()` in `modules/repos.sh` to remove early returns when components are already enabled. The script now verifies and ensures security and updates sections exist/were written correctly if missing or different.
- Created new `bootstrap_repositories()` function for systems with no active sources. Includes user dialogue for format selection (Trixie) or auto-classic (older versions), backup/restore safety, and cleanup of empty sources.list files post-bootstrap.
- Fixed false success reporting in `modules/firmware.sh` and `gaming.sh`. Added pre-checks to ensure APT sources exist before attempting `sed -i` modifications; if sources are missing, the script now triggers a full repository bootstrap instead of silently failing.
- Implemented post-write verification in firmware/gaming modules to confirm components were actually added before reporting success to the user.
- Generalized backports detection in `modules/utils.sh` (`is_backports_enabled()`) to scan all `*.list` and `*.sources` files rather than relying on fixed canonical filenames.
- Corrected test harness variable expansion order and trimmed whitespace from component parsing logic during development verification.
- Created dedicated `extras/java.sh` module for modular Temurin/Adoptium repository handling and isolated GPG key management.
- Implemented selective JRE/JDK installation paths: Gaming (Minecraft) vs Development environments with version control selectors.
- Enhanced user group membership logic (`_ensure_sudo_group`) to auto-configure administrative privileges on fresh installs.
- Introduced maintenance-friendly passwordless sudo for `apt`, `systemctl`, and shutdown commands via `/etc/sudoers.d/`.
- Added home directory ownership repair utility to fix root-owned files in user directories after improper `sudo` usage.
- Enabled visual password feedback (`pwfeedback`) toggle for enhanced terminal usability during authentication prompts.
- Refactored Debian 13/Trixie repository sourcing logic to ensure idempotency and prevent backports/duplicate sources conflicts.
- Updated Bullseye legacy modules (extras.sh, repos.sh) to exclude deprecated packages (`hx`, `vscodium`) and enforce Firefox ESR defaults.
- Cleaned repository configurations by removing obsolete `bullseye-updates` source entries to prevent dependency conflicts.
- Implemented NVTOP conditional detection logic ensuring display only on active Nvidia drivers or supported architectures (Trixie/Bookworm).
- Corrected `/modules/bullseye/extras.sh` menu mappings (Programming, Dev Tools) and verified package lists excluding incompatible tools (`hx`, `vscodium`).
- Integrated ClamAV security module with daemon state management and background scan execution flows in all Security menus.
