ja b0af3dcf12 Workstation optimization: Chrome cleanup, package purge, PCIe audit, service tuning 
- Chrome/Chromium cleanup (ADR 0006): removed 10GB chromium profile, broken PWA
  shortcuts, dead BROWSER_CDP_URL from .bashrc, restored Wayland chrome-flags.conf
- Package cleanup (ADR 0007): Tier 1-4 executed, 40 packages removed (KDE Plasma,
  ruby, love, xorg-server, kscreen/kscreenlocker), 45 cascade orphans purged
- Waybar USB module: auto-mount via udisks2, yazi integration, hover details
- Service tuning: disabled bluetooth.service, NetworkManager-wait-online.service
- hypridle fix: upgraded sdbus-cpp 2.3.0->2.3.1-1 (SEGV crash loop resolved)
- PCIe audit: GPU in wrong slot (PCIEX4 vs PCIEX16), 8x bandwidth loss documented
- D-Bus cleanup: removed stale org.kde.kwalletd6.service stub
- Ansible: all changes reflected in vars/main.yml and task files

Known Issues (2026-05-22 Boot Audit)

Domain Issue Status
PCIe slot GPU 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 Pending: physical move required
PCIe slot NVMe Samsung PM9A1 running Gen2 x4 (8 GT/s) instead of Gen3 x4 (16 GT/s). May resolve after GPU slot fix + BIOS Gen3 setting Pending: BIOS tuning
Idle daemon hypridle SEGV crash loop — sdbus-cpp 2.3.0 ABI break Fixed: sdbus-cpp upgraded to 2.3.1-1
Webcam (UVC) Device 1-10 has multiple UVC control failures (zoom/pan/tilt/iris non-functional due to firmware non-compliance) Known hardware limitation, core capture works
KVM /dev/kvm unavailable — libvirtd cannot use hardware acceleration Open — check BIOS VT-x/AMD-V
Wi-Fi regulatory regulatory.db firmware missing — channels restricted Open — install wireless-regdb
D-Bus Stale org.kde.kwalletd6.service file; dunst/kscreen naming mismatches Fixed: kwalletd6 stub removed; kscreen/kscreenlocker/libkscreen uninstalled (35 MiB)
XDG portals Deprecated UseIn key usage (portals.conf preferred) Low priority, functional

Removed (2026-05-22, ADR 0007): All X11 display managers (lightdm, sddm), X11 video/input drivers (xf86-*), X11 tools (xterm, xorg-xinit, x11vnc, etc.), entire KDE Plasma stack (kwin, plasma-desktop, plasma-workspace, plasma-nm, plasma-pa, powerdevil, etc.), and Dolphin (replaced by yazi). greetd+tuigreet is the active DM. Screenshots use grim+slurp+grimblast.
