check-claude-denylist

Audits Claude Code's two deny lists in ~/.claude/settings.json against what /opt/docker actually holds, so they stay correct by verification rather than by memory. Read-only; prints paths, never file contents. Exit 1 if anything needs attention.

Lives here rather than in /opt/docker because it reads personal harness config, and that repo is headed public.

Four checks, each mapping to a mistake that has actually happened:

• overbroad — a pattern denying a git-tracked file. Tracked means deliberately not secret, so this is the blanket-.env-wildcard mistake.
• mirror drift — permissions.deny only binds the Read tool; sandboxed Bash obeys sandbox.filesystem.denyRead instead. A path in one and not the other is a real hole. Compares coverage, not pattern text, since the two lists legitimately use different patterns for the same protection.
• fragile ** — denyRead's ** doesn't reliably match targets 0–1 segments below its anchor. Flags those, skipping ones a per-stack literal already covers.
• stale — a pattern matching nothing on disk. Harmless, but it means the list has drifted.

Run it after adding a service, moving a secret, or changing what the repo tracks.

backup-configs

bin/backup-configs is the sync automation: it copies each live file/dir in its MANIFEST into the repo, regenerates the package lists, and — if anything changed — commits (--push also pushes). Run it after any config change you want captured, or on a schedule.

Not covered by the manifest (edit these paths in the repo directly, or extend the manifest if they become worth automating):

• bin/* scripts themselves
• kde/applications/, kde/icons/ (Proton launchers/icons)

Restoring on a fresh install

Packages

sudo pacman -S --needed - < packages/pacman.txt
# then install an AUR helper if needed, e.g.:
paru -S --needed - < packages/aur.txt

KDE Plasma

Copy from kde/: kdeglobals, kwinoutputconfig.json, plasmarc, plasmashellrc, kwinrulesrc (has the Proton Mail alt-tab rule), kwinrc, konsolerc into ~/.config/.

Copy kde/konsole-keytabs/ into ~/.local/share/konsole/ and kde/kxmlgui5-konsole/ into ~/.local/share/kxmlgui5/konsole/ to restore the custom Konsole keyboard scheme and Copy/Paste shortcut rebinds.

KWin Tiling (DP-2 portrait monitor)

After a fresh install, KWin tiling on the secondary monitor resets on logout if other monitors have non-default tile layouts. Known Plasma 6.4+ regression.

Fix: Leave all other monitors at their default single-tile layout (don't configure tiling on them). Only configure tiling on DP-2. Set the 50/50 horizontal split with Super+T.

KWin Scripts

kde/kwin-scripts/<name> holds KWin scripts (currently cava-to-tv, which sends the cava/kitty TV visualizer window to the HDMI-A-1 output on open — the classic window-rule "Force screen" approach doesn't reliably win against a window that requests fullscreen immediately at launch).

1. Install: kpackagetool6 --type KWin/Script -i kde/kwin-scripts/<name>
2. The enabled flag (kwin4_script_<name>Enabled=true under [Plugins]) is already restored as part of kwinrc, but a freshly-installed script still needs loading for the current session: qdbus6 org.kde.KWin /Scripting loadScript ~/.local/share/kwin/scripts/<name>/contents/code/main.js <name> then qdbus6 org.kde.KWin /Scripting start
3. It auto-loads on future logins without step 2.

Proton App Icons

1. Copy PNGs to ~/.local/share/icons/hicolor/256x256/apps/
2. Copy .desktop files to ~/.local/share/applications/
3. Run gtk-update-icon-cache --force --ignore-theme-index ~/.local/share/icons/hicolor
4. Run kbuildsycoca6 --noincremental
5. Window rules are restored automatically via kwinrulesrc

systemd user units

systemd/ holds user-scope units (~/.config/systemd/user/, not /etc/systemd/system/):

Unit	Purpose	Schedule
docker-goroutine-watch.timer	captures a dockerd pprof goroutine dump if the count spikes (see bin/docker-goroutine-watch.py)	every 5 min

Install:

cp systemd/*.service systemd/*.timer ~/.config/systemd/user/
systemctl --user daemon-reload
systemctl --user enable --now docker-goroutine-watch.timer

The CrowdSec hub update, Invidious restart, IP2Location renewal, and Docker image prune timers that used to live here moved to /opt/docker/_helper/ (each has its own directory: crowdsec-hub-update/, invidious-restart/, ip2location/, docker-image-prune/) — they operate entirely on the docker stack, so the docker repo is the more natural home. Same for the docker.service TimeoutStopSec override, now at /opt/docker/_helper/docker-service-override.conf. See that repo's Maintenance doc.

btrfs maintenance (/mnt/external, run on fresh install)

Not tracked as repo files — create these by hand:

sudo systemctl enable --now btrfs-scrub@mnt-external.timer  # built-in unit

/etc/systemd/system/btrfs-balance-external.service:

[Unit]
Description=btrfs balance /mnt/external
ConditionPathIsMountPoint=/mnt/external

[Service]
Type=oneshot
ExecStart=/usr/bin/btrfs balance start -dusage=50 -musage=50 /mnt/external
IOSchedulingClass=idle
CPUSchedulingPolicy=idle

/etc/systemd/system/btrfs-balance-external.timer:

[Unit]
Description=Weekly btrfs balance /mnt/external

[Timer]
OnCalendar=weekly
RandomizedDelaySec=1h
Persistent=true

[Install]
WantedBy=timers.target

Then:

sudo systemctl enable --now btrfs-balance-external.timer

system/fstab: /mnt/external uses x-systemd.device-timeout=2,x-systemd.idle-timeout=60 to avoid a 90s hang when unplugged (fixed 2026-07-20).

sync-systemtray

Keeps systray applet layout mirrored across panels on multiple monitors. Has hardcoded containment/applet IDs (SRC_CONT, SRC_APP, TARGETS) at the top of the script — these are install-specific and need updating after a reinstall or if Plasma reassigns them.

Finding the current IDs

Find all systemtray applet headers:

awk '/^\[Containments\]\[[0-9]+\]\[Applets\]\[[0-9]+\]$/{header=$0} /plugin=org\.kde\.plasma\.systemtray/{print header}' ~/.config/plasma-org.kde.plasma.desktop-appletsrc

This gives three lines like [Containments][N][Applets][M] — one per panel. To determine which screen each belongs to, check the lastScreen= value for each containment:

grep -A5 '^\[Containments\]\[N\]$' ~/.config/plasma-org.kde.plasma.desktop-appletsrc | head -6

lastScreen=0 is the primary (source), 1 and 2 are targets.

Updating the script

Edit the constants at the top of sync-systemtray:

SRC_CONT = <panel_id for screen 0>
SRC_APP  = <systemtray applet id for screen 0>

TARGETS = [
    (<panel_id screen 1>, <systemtray applet id screen 1>),
    (<panel_id screen 2>, <systemtray applet id screen 2>),
]

Verify with --dry-run before applying:

sync-systemtray --dry-run
