# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
### Fixed
- hypridle SEGV crash loop (ADR N/A, hotfix): sdbus-cpp 2.3.0 had an ABI incompatibility causing hypridle to SIGSEGV in `libsdbus-c++.so.2` `registerSignalHandler`. Fixed by upgrading sdbus-cpp from 2.3.0-1 to 2.3.1-1 (Arch upstream, pulled ahead of Manjaro mirror sync). Also resolves latent ABI issues for hyprlock and xdg-desktop-portal-hyprland (2026-05-22).
### Added
- Waybar USB module: auto-mount USB sticks via udisks2, show hover details (device/model/size/fs/mountpoint), left-click opens in yazi, right-click ejects. Script at `~/.config/waybar/scripts/usb.sh`, Ansible-managed via `hyprland` role template `waybar_usb_script.sh.j2` (2026-05-22).
- `udisks2` explicitly listed in `hyprland_packages` (was transitive dep of Dolphin; now direct dep of USB module) (2026-05-22).
- Yazi optional deps provisioned via Ansible: `chafa`, `7zip`, `resvg` added to `hyprland_packages` (2026-05-22).
- X11 package removal list `hyprland_packages_remove` in `ansible/vars/main.yml` with corresponding task in `hyprland` role — removes `xclip` and `xsel` on Wayland-only system (2026-05-22).
- ADR 0006: Chrome/Chromium normalization and cleanup decision record (2026-05-22).
- New Ansible role `ansible/roles/system-upgrade/` that runs as the **first** role in `workstation.yml`. Performs a full `pacman -Syu`, dual-installs `linux612` (LTS, fallback) and `linux70` (stable, new default) kernels with matching headers, and verifies both initramfs images and GRUB menu entries post-install. Invoke stand-alone with `ansible-playbook ansible/workstation.yml --tags system-upgrade`; idempotent on re-runs (2026-05-18).
- `docs/adr/0002-kernel-and-nvidia-strategy.md` — ADR documenting the LTS+stable kernel choice and the `575xx → 595.71` NVIDIA migration for Hyprland/Wayland preparation (2026-05-18).
- Pre-flight safety gate in the new role: aborts if free space on `/` drops below `min_free_root_gb` (5 GiB by default) (2026-05-18).
- Comprehensive NVMe benchmark for Samsung PM9A1 before firmware update: SMART health, hdparm, fio seq/rand benchmarks (2026-04-02). See `docs/tech/nvme-benchmark-pre-gxa7802q.md`.
- CLI suite update script `scripts/update-cli-suite.sh` for Manjaro/Arch tool maintenance (2026-04-02).
- Created formal stability tests report documenting the 2026-03-17 memory management improvements (2026-03-17).
- System stability improvements: enabled `systemd-oomd` and `zswap` via Ansible (2026-03-17).
- Memory resource limits for Firebird and Mailpit Docker containers (2026-03-17).
- Implemented and verified advanced memory optimizations: zswap 30% pool, THP madvise, and proactive kernel reclaim tuning (2026-03-17).
- Integrated 16GB swap file management into Ansible roles for consistency and persistence (2026-03-17).
- Comprehensive health report for `mw-pfeddersheim-workstation` (2026-03-09).
### Removed
- `alesi-routine-morning.service` / `alesi-routine-morning.timer` user-level systemd units — daily 07:45 morning routine was failing (exit 128, git outside repo). Script `scripts/daily-routine.sh` retained for manual use (2026-05-26).
- Tier 1 package cleanup (ADR 0007): removed 25 X11/KDE/legacy packages via Ansible — lightdm, lightdm-slick-greeter, lightdm-settings, sddm, sddm-kcm, sddm-breath-theme, xf86-video-{amdgpu,ati,intel,nouveau,vesa}, xf86-input-synaptics, xterm, xorg-{twm,xinit,xkill,server-xvfb}, x11vnc, numlockx, startup-notification, illyria-wallpaper, ntp, spectacle, pamac-tray-icon-plasma. All have Wayland-native replacements already in use. Frees ~80-120 MiB direct + cascade deps (2026-05-22).
- Tier 2 package cleanup (ADR 0007): removed KDE Plasma stack — kwin, plasma-desktop, plasma-workspace, kdeplasma-addons, plasma-nm, plasma-pa, plasma-x11-session, kde-gtk-config, powerdevil, xdg-desktop-portal-kde, plasma-integration, dolphin, dolphin-plugins, kdegraphics-thumbnailers. Plus 45 cascade orphan deps. Dolphin replaced by yazi. Frees ~400 MiB total (2026-05-22).
- Tier 3 package cleanup (ADR 0007): removed ruby (38 packages), love, xorg-server, xf86-input-libinput. No active Ruby usage; no .love files; xorg-server no longer required (xorg-xwayland is independent). Frees ~30 MiB (2026-05-22).
- Tier 2b: removed kscreen, kscreenlocker (KDE screen management) + 10 cascade orphan deps (libkscreen, kdeclarative, plasma5support, libksysguard, etc.). Freed 35 MiB. Replaced by wlr-randr/hyprlock (2026-05-22).
- Removed stale `org.kde.kwalletd6.service` D-Bus stub from `~/.local/share/dbus-1/services/` (was a broken `Exec=/bin/true` placeholder) (2026-05-22).
- Disabled `bluetooth.service` (no BT hardware) and `NetworkManager-wait-online.service` (unnecessary on wired workstation, speeds up boot) (2026-05-22).
- Documented PCIe slot misconfiguration: GPU (GTX 1050 Ti) installed in bottom PCIEX4 slot (PCIe 2.0 x4, ~2 GB/s) instead of top PCIEX16 (PCIe 3.0 x16, ~16 GB/s). 8x bandwidth loss. Physical move required. NVMe also running at Gen2 instead of Gen3 (2026-05-22).
### Changed
- Tier 4 package reclassification (ADR 0007): 13 "Misc" packages reclassified to functional domains in `docs/tech/stack.md` — uv→Python Toolchain, jq→Shell/Terminal, inxi→Hardware, lsof/zram-generator/mkinitcpio-openswap→Core OS, iproute2/openresolv→Network, perl-image-exiftool/icoutils/innoextract-git→Dev Tools, opencl-headers→GPU Compute, libxnvctrl-580xx→NVIDIA. No packages removed; documentation-only change (2026-05-22).
- Chrome/Chromium normalization: removed all Chromium artifacts — `~/.config/chromium/` (1.4 GB), `~/.local/chrome-cdp/` (8.6 GB), 13 broken PWA `.desktop` files, 4 stale PWA manifests from Chrome Preferences, `chromium-widevine` orphan package (17 MB). System now uses `google-chrome-stable` exclusively with Wayland-native flags (2026-05-22).
- `~/.bashrc`: removed dead `BROWSER_CDP_URL` auto-population (curl to localhost:9222 on every shell startup) (2026-05-22).
- `~/.config/chrome-flags.conf`: restored Ansible-managed Wayland flags (`--ozone-platform=auto`, VA-API on NVIDIA, `--use-angle=gl`, Vulkan disable) — was drifted to X11 mode with garbage flags (2026-05-22).
- Waybar config: added `custom/usb` module to `modules-right` bar (2026-05-22).
- Waybar style: added CSS for `#custom-usb` with hover state and color classes (`usb-none`, `usb-unmounted`, `usb-mounted`) (2026-05-22).
- **Executed `system-upgrade` playbook on the live workstation** (2026-05-18). `pacman -Syu` upgraded **1103 packages**; kernel set now `linux612 6.12.85-1` (LTS, was 6.12.77-1) + `linux70 7.0.3-1` (NEW); NVIDIA migrated to mainline `595.71.05` for both `linux612-nvidia` and `linux70-nvidia`; legacy `*-nvidia-575xx` packages removed. Both `/boot/initramfs-6.12-x86_64.img` (54 MB) and `/boot/initramfs-7.0-x86_64.img` (122 MB) generated; GRUB regenerated with menuentries for both kernels. **Reboot required**: select `linux70` from the GRUB "Advanced options for Manjaro Linux" submenu to activate the new kernel and NVIDIA 595.71.05 modules. Logs: `logs/system-upgrade-20260518-101253-live.log`.
- NVIDIA driver migrated from the pinned `*-nvidia-575xx` (575.64.05) branch to the mainline `*-nvidia` (595.71.05) branch via the new `system-upgrade` role. `linux612-nvidia-575xx`, `nvidia-575xx-utils`, `lib32-nvidia-575xx-utils`, `nvidia-575xx-settings` are removed; `linux612-nvidia`, `linux70-nvidia`, `nvidia-utils`, `lib32-nvidia-utils`, `opencl-nvidia`, `nvidia-settings` are installed in one atomic pacman transaction (2026-05-18).
- `ansible/workstation.yml`: `system-upgrade` registered as the first role, guarded by `when: os_type == 'archlinux'`, with tag `system-upgrade` (2026-05-18).
- `ansible/vars/main.yml`: added `kernel_packages`, `nvidia_kernel_modules`, `nvidia_userspace_packages`, `nvidia_packages_to_remove`, `min_free_root_gb` so future kernel/driver pins are a one-line change (2026-05-18).
- `docs/tech/setup.md`: new bootstrap step "Run system upgrade & kernel install" before the main playbook, with `--tags system-upgrade` examples and a reboot-into-`linux70` callout (2026-05-18).
- Samsung PM9A1 NVMe firmware update applied: GXA7401Q → GXA7801Q (non-SED variant, reboot pending to activate). All nvme-cli steps succeeded (2026-04-02).
- Corrected firmware research: GXA7802Q is SED-only (`00B07`); non-SED drives (`00B00`) require GXA7801Q. Updated `docs/tech/firmware-update-research.md` with naming convention and correct source.
- Updated `.gitignore`: added `logs/` and `docs/tech/capabilities/` exclusions (2026-04-02).
- Increased system swap file size from 4GB to 16GB to prevent OOM-related system hangs (2026-03-17).
- Updated system status in `README.md` and `docs/tech/workstation-health.md` (2026-03-17).
- Cleaned up deprecated software information from `docs/tech/stack.md` (2026-03-13).
- Synchronized software versions across documentation files (2026-03-13).
### Fixed
- Resolved kitty cursor keys not working by disabling the `TERM=xterm-256color` override in `.bashrc`, allowing Kitty to correctly set `TERM=xterm-kitty`. Added Ansible management for `kitty.conf` to ensure proper terminal behavior and shell integration (2026-05-19).
- `system-upgrade` role: GRUB menu assertion now matches Manjaro's real `menuentry 'Manjaro Linux (Kernel: X.Y.Z-MANJARO x64)'` format (counted per-kernel-family) instead of the wrong `menuentry .*linux(612|70)` regex that always returned 0 hits on Manjaro and broke the live run with a false-negative failure (2026-05-18).
- `system-upgrade` role: migration task `changed_when` now matches pacman's progress lines `^<!--(SECTION)-->(N/M)<!--(--SECTION)-->s+(installing|upgrading|removing)s` instead of plain substring matching, so the role's own echo lines no longer trigger spurious `changed=true` on idempotent re-runs. Verified: second live re-run reports `ok=16 changed=0 failed=0 skipped=5` (2026-05-18).
- Resolved system unresponsiveness issue by addressing critical memory/swap pressure with increased headroom and proactive OOM killing (2026-03-17).
- Identified failed `archlinux-keyring-wkd-sync.service` in system health check.
