412 lines -> 135, with the nine functions in lib/music_detect.sh (133),
lib/music_monitor.sh (91) and lib/music_status.sh (85).
find_music_services and kill_music_services stay together: the first
writes MUSIC_FOUND_PROCESS/MUSIC_FOUND_WINDOW and the second reads them,
so splitting between them would thread mutable state across files.
The test suite caught what the static checks could not. The harness
copies the script into a temp worktree to stub common.sh, and copied
exactly one file -- so after the split every source line failed and the
script died before any behaviour under test ran. Teaching it to copy
lib/ too is a harness fix under decision 8: no assertion changed, the
same five checks run, exit 0 before and after.
bash -n also earned its keep: the first splice dropped notify_user's
closing brace, and shellcheck reported that only as SC1094 "parsing of
sourced file failed" against the entry.
One rename, not a suppression: monitor_loop's local `music_services`
became `active_services` after shellcheck flagged SC2153 against the
MUSIC_SERVICES config array now visible in the same file.

Twelve prose violations to zero. Eight files split into per-topic
subdirectories with the original left as an index; both SKILL.md files
keep their frontmatter so discovery still works, with detail moved to
references/.
Deleted docs/cleanup-2026-05/ (7 files) and linux_configuration/docs/
VERIFICATION.md on the user's ruling: unreferenced records of finished
work whose rules are now enforced by the polling, shellcheck and shfmt
hooks. PACMAN_WRAPPER_SECURITY.md was split instead - unlike those, it
documents live guarantees.
Every split verified by a sorted diff against HEAD: zero content lines
lost, only the new headings and index links added.

install_ublock.sh patches the same wrapper install_leechblock.sh already
targets, always rewriting --load-extension into a single comma-joined
flag rather than appending a second occurrence — verified empirically
that Chromium is last-wins across separate --load-extension flags and
would otherwise silently drop LeechBlock.
seed_ublock_storage.js previously hardcoded uBlock Origin's Chrome Web
Store extension ID, but --load-extension (unpacked) loads get a
synthetic, install-path-derived ID instead. It now reads the real ID
back out of the profile's own Preferences file, with a --ext-path
override for installers whose package path differs from Arch's.
install_ungoogled_chromium_ubuntu.sh's UBLOCK_EXT_PATH was an unverified
guess (/usr/share/webext/ublock-origin-chromium); corrected to the real
Debian/Ubuntu package path confirmed via packages.ubuntu.com.

is_blocked_package_name compared raw pacman -U <file>.pkg.tar.zst
arguments against whitelist entries, which never matched since yay
always installs AUR packages this way. Added strip_pkgfile_suffix()

Thorium was "closing and dying randomly" with no evidence anywhere.
Two independent structural causes, both now fixed:
1. Crashpad was never enabled -- no crash_reporting consent key and an
empty crash DB, so no minidump was ever written.
2. stderr from a dmenu/.desktop launch reaches no terminal and no
journal. The only Thorium lines ever seen in the journal came from a
systemd-launched instance, which is why they survived.
browser-preexec-wrapper.sh now gives every Chromium-family launch its own
log under $XDG_STATE_HOME/browser-crash-logs: a VRAM/RAM/kernel/driver
snapshot before start, the browser's stderr, and on exit the exit code,
decoded signal, and a SECOND VRAM snapshot. Those two snapshots plus the
signal are the discriminator between the live hypotheses -- a VRAM death
shows NVRM/NV_ERR_NO_MEMORY or near-full VRAM at exit, a stale-binary
death shows SIGSEGV with the GPU idle. Root cause is deliberately NOT
asserted here; the next crash decides it from evidence.
Three details that are load-bearing rather than incidental:
- The exit record is written from a signal trap, not inline after
`wait`. If the wrapper itself is killed, an inline block never runs
and the log ends mid-stream with no verdict -- indistinguishable
from a browser that is still running.
- The browser is a direct redirect, NOT a pipe into a size filter: in
a pipeline `wait` reports the last element's status, discarding the
browser's signal, which is the one fact worth capturing.
- Logs are capped by bytes as well as count. Measured: ~2 MB per 45s
of navigation (65% VERBOSE1 net/TLS chatter), ~0 while idle. Count
alone would not bound disk use, and a full disk causes exactly the
random deaths under investigation.
setup_periodic_system.sh: rewrite Chromium "app mode" .desktop entries
(Exec=/opt/<browser>/...) to go through /usr/local/bin. These are
auto-generated and bypass the wrapper entirely, so neither the flags file
nor the logging applied to them -- five Thorium entries were found still
launching without the --disable-gpu-compositing mitigation added on
2026-07-25, two weeks after the fact. Runs on every install because
Chromium regenerates the files.
pacman_whitelist.txt: allow the exact package name `librewolf`. The
`librewolf` keyword stays blocked, as do all other Firefox forks. It is
LeechBlock-enforced via /etc/librewolf/policies (force_installed), so
this is not an unfiltered escape hatch; it is needed because Chromium's
MV2 sunset ends full uBlock Origin with all filter lists, which the Gecko
build keeps.
Verified: shellcheck clean, no lint suppressions; fake-browser SIGSEGV
and wrapper-SIGTERM both produce a verdict; trim watchdog bounds a
runaway log; kill -SEGV on the real /opt/thorium-browser/thorium wrote
"exit code: 139 / died on signal: 11 (SEGV)"; librewolf installs and
loads with uBO + LeechBlock active.

The shellcheck hook ran with --severity=warning, so info- and style-level
findings never failed a commit. 222 had accumulated across 94 of 244 shell
files. They were not all style noise -- six were bugs:
- Five scripts in single_use/misc/testsAndMisc-bash/ sourced
$SCRIPT_DIR/../../lib/common.sh, one directory too shallow. Nothing exists
at that path, so all five failed at runtime.
- setup_personal_website.sh and setup_kcd2_dice_solver.sh called usage()
(which ends in `exit 0`) and then `exit 1` for an unknown command. The
exit 1 was unreachable, so a typo'd subcommand reported SUCCESS.
- Six i3blocks scripts had a `# shellcheck source=` directive missing the
scripts/periodic_background/ path segment. The stale path had silently
disabled source-following for all of them.
- diagnose_arch_performance.sh word-split a newline-joined file list; when
the find came back empty, awk got no file operands, fell through to
reading stdin, and the diagnostic hung.
- lib/common.sh's handle_arg_help_or_unknown ended in an unreachable
`return 0` while documenting "Returns: 0 if handled" -- a contract no code
path could satisfy.
- deploy.sh's SCRIPT_DIR is reassigned by config.sh, which it sources at top
level, and config.sh can repoint it at the on-device path
/data/local/tmp/focus_mode. Renamed to DEPLOY_DIR.
The SC1091 bulk (81 findings) was resolved rather than silenced: .shellcheckrc
sets external-sources + source-path=SCRIPTDIR so sourced files are actually
followed and analysed. That is what surfaced the i3blocks and deploy.sh bugs.
17 `# shellcheck disable=` directives remain, each with a written reason, and
only where the finding is provably wrong: injection-test payloads that must not
expand, literal source text being grepped for, POSIX sh scripts on the phone
where arrays do not exist, and source paths that only exist at runtime.
Everything else was fixed in code.
Verified in a CLEAN worktree, not just my own tree. config.sh sources the
gitignored config_secrets.sh, which exists locally but not in a fresh checkout;
a working-tree-only check passed while ci_mirror.sh -- which lints HEAD in a
clean worktree, exactly as CI does -- failed on it.
The gate is verified to bite: a file whose only finding is SC2016 (info) fails
the hook, while the old --severity=warning gate exits 0 on it.
third_party/ is excluded -- vendored upstream, matching the prettier hook.
Not fixed, reported: check_polling_antipatterns.sh carries a pre-existing
SC2034 disable that hides a real bug -- its `patterns` array is never used, so
the checker detects nothing. Confirmed unchanged by this commit.

pacman intermittently freezes at its FIRST PreTransaction hook - 5 abandoned
transactions since 2026-07-29, stalls of 4 minutes to overnight, always fine on
retry. This investigates it and repairs the real defects found on the way.
The stall is NOT fixed, and deliberately so: no verified defect was found, so
nothing pacman-side was changed.
- Not guard-lib. /etc/guard-lib/targets was empty, so that hook script
provably exits in milliseconds. The failures share POSITION (first hook of
the transaction), not identity: one stall hit the hosts hook back when that
one ran first.
- Not reproducible on demand. 65 real transactions (40 idle, 25 under 2.6 GB
of memory pressure) produced zero stalls. Against the historical 4-in-56
rate that is ~0.9% likely, so the trigger is conditional on something a
synthetic load does not recreate. Memory pressure is untested at the load
that actually occurred - not refuted.
So diagnose_pacman_hook_stall.sh drives real transactions with a watchdog, and
its --watch mode passively captures /proc/<pid>/{stack,wchan,syscall}, the
process tree, meminfo and PSI from the next REAL stall. No pacman-side fix
should ship before that dump exists.
Three real defects were found and fixed:
1. The deployed pacman wrapper was 19916 B against a 27510 B source, never
sourcing the shared pacman_lock_lib.sh that makepkg_wrapper already used.
It hid because check_pacman_wrapper() only tested that files EXIST. Both
installers now write a drift manifest covering source AND installed hashes;
the checker replays it with sha256sum -c and fails closed when it cannot
verify. Manifest paths are absolute - relative ones resolve to nothing under
systemd's cwd=/ and would have looped reinstalling forever.
2. The guard-lib migration (66c4698) was never finished here: guard-lib was
installed with zero registered targets while the legacy hosts-guard layer did
all the work, so every transaction ran two PreTransaction hooks and the first
one did nothing. migrate_hosts_guard_to_guard_lib.sh registers hosts,
nsswitch and resolved, retires the legacy hooks and units, and has a
--rollback that was actually exercised. Plugins install to a stable path
because guardctl records absolute plugin paths. Side effect: one hook pair
instead of two, transactions ~5-6s -> ~2-3s.
3. "One heavy job at a time" was a rule a human had to remember. heavy_job_lock.sh
makes the overlap impossible: one system-wide flock shared between root and
the user (a per-user lock would give root's pacman and the user's builds
separate locks and no exclusion at all). Wired into pacman TRANSACTIONS only
- read-only queries stay instant - plus makepkg_capped and the coverage hook.
Always fails open.
Two bugs surfaced only by running --rollback, both of which briefly left
/etc/hosts with no immutable flag: fg_uninstall clears +i on its way out while
legacy watchers only fire on PathModified, and `((i > 20)) && break` left the
loop body's status at 1, which under set -e aborted the rollback silently - but
only when the loop actually ran, so --dry-run looked healthy.
Not migrated: the shutdown-schedule guard (/etc/shutdown-schedule.conf does not
exist here). Not wired: Flutter/Gradle builds, which have no single entry point.

Caps CPU (amd-pstate-epp) and GPU (nvidia-smi power limit) during the
existing night-lockdown window instead of migrating services to a
Raspberry Pi (tried, abandoned after SSH auth failed). A more aggressive
GPU PCI-unbind option is built but left disabled by default.
Also fixes an unrelated live incident found while testing: dnsmasq (this
PC's LAN DHCP/DNS server) had died with zero error logged, breaking WiFi
for every device on the network. Added a watchdog timer mirroring the
existing shutdown-timer-monitor-watchdog pattern, and whitelisted the
Tapo smart plug app so the overnight power reading is checkable during
the phone's curfew window.

The unlock script started morning-routine.service on every staggered trigger
(05:00/05:15/05:30/06:00/07:00) on alarm days. That was a workaround for the
always-on lockdown removing the hibernate/resume event the alarm used to ride
on — reasonable when nothing else could fire it.
Something else fires it now. wake-alarm-trigger.timer ticks every minute and
starts morning-routine.service at the time the phone synced, with a catch-up
window for a suspended or just-booted machine. Keeping both meant two
independent triggers, one of which ignores the phone entirely.
That is not hypothetical: on 2026-07-20 the phone was set to 08:00 and the
alarm went off at 07:00, started here, with no wake-alarm-trigger "Firing" line
in the journal at all. The 08:00 fire then landed as a no-op because this
07:00 run had left morning-routine.service still active.
Drop maybe_start_morning_alarm() and both call sites, plus the config that
went dead with it (ALARM_DAYS_DOW, MORNING_ROUTINE_UNIT, the alarm_started_date
marker). MIN_WAKE_AFTER_LOCKDOWN_HOURS stays — the wake-floor trigger uses it.
The lockdown's actual job — console/GUI restore, unmute, unmasking the login
surface — is untouched.
The only starters of morning-routine.service left are wake-alarm-trigger.timer
(primary) and the system-sleep hook (resume backstop).

The alarm floor (lockdown-entry + 8h) from the previous commit still relied
on the fixed 05:00/05:15/05:30/06:00/07:00 unlock triggers to ever re-check
it. Shutdown time is configurable (/etc/shutdown-schedule.conf, changed by
the screen_locker sick-day feature) and can vary night to night, so a late
enough lockdown (e.g. 23:30) pushes the floor past every remaining trigger
(07:30 > 07:00) and the alarm would silently never fire that morning.
Enter script now schedules a transient systemd-run --on-calendar one-shot
timer at exactly lockdown-entry + MIN_WAKE_AFTER_LOCKDOWN_HOURS, computed
from the real lockdown timestamp rather than assumed shutdown hours. It
re-runs the idempotent, self-dedup'd unlock script, guaranteeing the alarm
gets a correctly-timed chance regardless of what time lockdown started.

The 23:00 lockdown -> 05:00 unlock cycle exposed three live bugs: a visible
console-text flash before the screen went black (blank_console only ran once
systemctl stop lightdm.service fully returned, leaving a gap), DP-0 needing a
manual xrandr/replug after wake, and the morning alarm firing only 6h after a
late lockdown entry instead of waiting a full 8h.
- Blank the console continuously in a background poller for the whole GUI
teardown instead of a single after-the-fact call.
- Retry autorandr --change against a saved profile after lightdm restarts.
- Stamp lockdown-entry time and gate the alarm on entry + 8h, decoupled from
the console/GUI-restore idempotency so it can fire on a later staggered
trigger instead of only the first one.
- Add DRY_RUN NOTE banners so a clean dry run is never mistaken for proof the
console-blank and autorandr fixes work for real (they need a live cycle).

focus_mode_daemon.py has been 509 lines since 22e22c1, over the repo's
cap. It went unnoticed because the Python tests workflow only triggers on
python_pkg/** changes, so that commit never ran CI; the next commit to
touch python_pkg/ exposed it and turned main red.
Extract configuration, logging, notification, /proc process inspection and
the killers into _focus_mode_lib.py, leaving the daemon its policy: the
whitelist, the FocusMode state machine, and main(). log/notify move with
the process code that calls them, so the dependency runs one way and there
is no cycle. The helper is underscore-prefixed and registered in pylint's
init-hook path, mirroring the existing usage_report.py / _usage_report_*.py
sibling-import precedent.
The daemon runs from a symlink in /usr/local/bin, so a sibling import only
works if Python resolves that symlink before setting sys.path[0]; verified
that it does, and the installer symlinks rather than copies, so the sibling
travels with it. Confirmed against the running service: restarts clean and
resumes enforcing, process detection unchanged, status output matches the
pre-split version.
Structural only; no behaviour change.

install_focus_mode_daemon.sh copied the script to /usr/local/bin, so the
deployed daemon went stale the instant the repo file was edited: what you
run stops matching what you read, with nothing to tell you. That is not
hypothetical - the zombie-detection fix in 22e22c1 sat in the repo while
a months-old copy at /usr/local/bin/focus-mode-daemon went on entering
GAMING mode and killing browsers. It only surfaced because the deployed
copy was checked by hand.
Link instead of copy, so editing the repo file IS deploying it. Also
chmod +x the source, since a symlink takes its executability from the
target rather than from an install mode.
uninstall now guards with [[ -e || -L ]] rather than [[ -f ]]: both -f
and -e follow the link and report false when the target is gone, which
is exactly the case (repo moved or deleted) where a stale link most
needs clearing.
The link resolves into the user's checkout, so /usr/local/bin/... is only
as trustworthy as that path. Fine here - focus-mode runs as a systemd
*user* service, crossing no privilege boundary. Not a pattern to copy for
anything root runs.
Verified: stat -L reports the same inode (92274745) for the deployed path
and the repo file; appending a marker to the repo file makes it appear at
/usr/local/bin/focus-mode-daemon immediately, with no reinstall; a link
to a missing target is now removed by uninstall where [[ -f ]] skipped it.

Focus mode flapped in and out of GAMING mode every few seconds and killed
browsers while no Steam was running. The pattern matching was not at
fault: the daemon was correctly seeing a process named "steam". That
process was a root-owned zombie.
A total gaming block on 2026-07-04 purged the Steam client and it was
never reinstalled, but steam-backlog-enforcer kept trying to launch it
through an orphaned /usr/local/bin/steam wrapper still pointing at the
deleted /usr/bin/steam. Each launch died on exec and, never being reaped,
lingered as a dead process that still carried the name "steam" - which
this daemon counted as a live Steam.
get_running_processes() now reads /proc/*/stat rather than /proc/*/comm
and skips state Z. Both cost one read per PID, so the poll loop stays
fork-free, but stat also carries the process state. _parse_stat() uses
rpartition(')') because a process name can itself contain spaces and
')', which naive whitespace splitting would corrupt. Names are truncated
to 15 chars in stat exactly as in comm, so the existing patterns match
unchanged.
Verified against the live zombie, before the enforcer was fixed:
zombies on system now : ['steam']
OLD (/proc/*/comm) sees 'steam' : True
NEW (zombie-filtered) sees 'steam' : False
dropped by filter : ['steam']
and non-regression on real processes: a synthetic live 'steam' and a
'steam_app_29687' game both still return True. It skips zombies, not
Steam. Running `focus-mode-daemon` now reports "Browser detected -
entering BROWSING mode" with no GAMING flapping.
The zombie source is fixed separately in steam-backlog-enforcer d54df3a;
this is the durable guard against any future one.
Note: install_focus_mode_daemon.sh copies rather than symlinks, so
/usr/local/bin/focus-mode-daemon was a stale copy without this fix.
Reinstalled. Editing this file alone never changes what runs.

The digital-wellbeing curfew powered the PC off at 21:00, which also took
down every service this machine hosts (Gitea, the Caddy TLS edge, SyncYomi,
the personal site, Open WebUI, Joplin, dufs, ollama, dnsmasq, wg-quick,
sshd). Keep the curfew's lockout, drop the power-off: the machine now stays
on with the GUI torn down, the TTY login surface masked, the console blanked
and the RGB killed, and restores itself at 05:00.
The fortress still owns the schedule (immutable config, ratchet, monitor,
watchdog); only its terminal action is swapped for night-lockdown-enter.sh.
The reversal deliberately lives outside the fortress so a bug in the lock
path can never take the recovery path down with it.
Verified in production overnight: lightdm down 21:00:04 -> 05:00:00 while
all 7 containers stayed "Up 14 hours" and kept serving; ticks idempotent all
night; 05:00 unlock fired.
Notable fixes found along the way:
- Wake alarm regression: it only ever fired on resume-from-hibernate, so an
always-on machine silently killed it. The unlock now re-fires
morning-routine.service on alarm days (the Mon/Fri/Sat/Sun gate lived in
the removed rtcwake branch, not in the alarm).
- Morning boundary -le -> -lt, so 05:00 no longer races the unlock.
- Mask getty@ only; autovt@ is an alias of it and masking it errors.
- Persist LOCKED before the session-killing teardown, else a kill mid-lock
leaves state=UNLOCKED and the unlock no-ops, stranding the machine.
- Blank the console without DPMS: FB_BLANK_POWERDOWN drops the DisplayPort
link and the GPU never re-trains it (DP-0 needed a physical re-plug).
- RGB: openrgb-git 0.9.2148's CLI returns before detection finishes, so every
call silently no-op'd while exiting 0. Stable openrgb 1.0rc3 fixes it. Use
static+black, not "off" (the ZOTAC has no Off mode; the ASRock ignores it).
- Validate the generated config with bash -n: its heredoc must stay unquoted,
so a stray backtick executes and corrupts the file.
Thu-Sun 22->21 aligns the source with the canonical schedule screen_locker's
sick-day feature ratcheted in on 2026-07-03; the ratchet only permits
same/stricter, so the script was otherwise un-re-runnable.

Three of the four remaining items were scripts hardcoding assumptions that
stopped being true — not real drift.
hosts (phantom warning): check_hosts looked for 10-unlock-etc-hosts.hook /
90-relock-etc-hosts.hook, gone since the guard migrated to guard-lib's generic
unlock-all/relock-all hooks. Match what pacman_wrapper.sh already treats as
authoritative (legacy pair still accepted).
focus_mode (never installable): install_focus_mode_daemon.sh calls
`systemctl --user`, but the checker invokes it via `sudo -u <user>` from root —
sudo changes the UID but grants no session, so XDG_RUNTIME_DIR /
DBUS_SESSION_BUS_ADDRESS were unset and it died at daemon-reload on every
automated run. Derive them from the effective UID. Now enabled+active.
compulsive_blocker (discord never limited): REAL_BINARIES hardcoded
/opt/discord/Discord — another discord package's layout. This one ships only
/usr/bin/discord, a bootstrap that downloads the app into ~/.config/discord/
and execs ~/.config/discord/Discord (a version symlink its updater maintains),
so the `[[ -x $real_binary ]]` gate failed forever. Exec the preserved LAUNCHER
(/usr/bin/discord.orig) so Discord's bootstrap/self-update still runs. Two
supporting fixes: the gate skips -x when the exec target IS the wrapper's own
.orig (the wrap creates it — chicken-and-egg), and PROCESS_MATCH is added
because the launcher exec()s away, so pgrep -f on '.orig' matches nothing and
auto-close/kill/running-state would have silently no-opped.
vbox_hosts: skipped -> n/a with a reason. VirtualBox is absent AND blocked by
pacman policy ("can bypass /etc/hosts restrictions"), so the check is not
applicable, not ducked. Installing it to satisfy a hosts check would open the
hole that check exists to close.
Also removed thesis_tracker (unused; unit not-found, script never installed).
Verified: every service ok, vbox_hosts n/a, zero errors, zero warnings.

An immutable tracked file with uncommitted edits breaks every commit/push:
pre-commit clears unstaged changes with `git checkout -- .`, that unlink
fails ("Operation not permitted"), the context manager aborts, and the
restore never runs — silently reverting the user's OTHER unstaged edits
(seen twice today; an unrelated i3/config WIP had to be recovered from
pre-commit's rescue patch).
Enforcement is unaffected and does not depend on the source being locked:
/etc/shutdown-schedule.conf stays chattr +i, guard-lib keeps a canonical
snapshot + path watcher that re-enforces it, the monitor service protects
the timer, and screen_locker's ratchet only accepts same-or-stricter
values. Editing this source changes nothing until setup is re-run as root,
which rewrites the guarded config anyway.

Vendored makepkg's run_pacman() waits on /var/lib/pacman/db.lck existence
with no timeout BEFORE invoking pacman, so an orphaned lock hangs
`makepkg -i` forever ("Pacman is currently in use, please wait...") and
the pacman wrapper's stale-lock cleanup never gets a turn. Wrap makepkg
(mirroring the pacman-wrapper pattern) to clear an orphaned lock up front.
- Extract stale-lock logic into shared pacman_lock_lib.sh; pacman_wrapper
sources it after integrity verification and it is in the SHA256 manifest
- makepkg_wrapper: pre-flight clear for -i/--install; bypass on FAKEROOTKEY
and non-install; FAIL OPEN if the lib is missing (never brick makepkg)
- Cross-user pacman_process_running() pgrep guard: unprivileged makepkg can
detect a root pacman its own fuser cannot see (avoids removing a live lock)
- Upgrade survival: rewrap hook (Install/Upgrade only) + check_makepkg_wrapper
drift verifier + both wrappers wired into the hourly periodic driver
- Fix reorg path bugs: stale ~/linux-configuration periodic path,
$CONFIG_DIR/hosts -> scripts/periodic_background/hosts, test WRAPPER_DIR;
refresh .orig only when target isn't already our symlink (no exec loop)
- Tests: test_makepkg_wrapper.sh (18) incl. hook Operation validity; add
lib-integrity coverage to test_pacman_wrapper_security.sh (also path-fixed)

Add a self-expiring override system so specific late-night live events
(2026 World Cup matches) can be watched without the auto-shutdown killing
the PC, without weakening the permanent schedule ratchet:
- shutdown-override-manager.sh (add/list/remove): add is friction-gated
(typed confirmation phrase + 30s delay, max 12h, max 3 windows) and
writes absolute-epoch windows to /etc/shutdown-schedule-overrides.conf.
- day-specific-shutdown-check.sh now skips the shutdown decision inside an
active window (pruning expired entries) and gained a DRY_RUN guard around
rtcwake/poweroff/hibernate for safe testing.
i3blocks shutdown_countdown.sh: show the exact next-shutdown clock time
(not a relative countdown), show the overridden end time in green when an
override is active or will rescue the upcoming shutdown, and make the
skip-dates check fork-free (builtin read loop) so the hot path spawns no
external processes.
install.sh: deploy i3blocks by symlinking each repo file into
~/.config/i3blocks instead of cp -r (the source of silent drift), cd to
the script dir so it runs from anywhere, and chmod +x only *.sh so the
config file stays 0644.
Repair the previously-dead i3blocks regression suite (stale path), update
the shutdown assertion to the new absolute-time output, add hermetic
override coverage, and keep the <=1-exec fork-count guarantee.

Replaces the bespoke chattr/bind-mount/systemd-watcher implementations for
/etc/hosts and /etc/shutdown-schedule.conf with the new shared guard-lib
(~/guard-lib, guardctl), so screen-locker and steam-backlog-enforcer's new
block-gaming feature stop maintaining parallel copies of the same
tamper-resistance mechanism.
- pacman_wrapper.sh: pre/post hook fallbacks now call guard-lib's generic
unlock-all/relock-all scripts (covers every registered guard instance,
not just /etc/hosts)
- setup_midnight_shutdown.sh: installs/updates its guarded config via
guardctl file-guard instead of hand-rolled chattr + systemd unit
generation; the schedule ratchet logic (block-if-more-lenient) stays
bespoke since guardctl's generic unlock can't represent it
- new hosts/guard/plugins/nsswitch-plugin.sh, resolved-plugin.sh
Also fixes, at user's request even though pre-existing: 3 shellcheck
SC2329 false positives in pacman_wrapper.sh (functions invoked indirectly
by name, not actually dead) and 1 SC2001 style warning (echo|sed VM-name
extraction replaced with parameter expansion, verified equivalent output).

The hibernate-on-alarm-night case block in create_shutdown_check_script()
escaped $ as \$ for an unquoted heredoc, but the heredoc is opened with the
quoted delimiter <<'EOF', so the backslashes were written literally into
the deployed check script. Every timer fire since commit 0d54c5d hit a bash
syntax error and exited before evaluating the shutdown window, so the PC
never auto-shut-down (confirmed failing at 23:00/23:01 last night and 07:01
this morning). Also fixed an off-by-one (seq ... 24 -> 23) that was emitting
invalid OnCalendar=24:00:00 entries systemd had to ignore.

Split diet_guard/_gatelock.py, wake_alarm/_alarm.py, and the
usage_report.py/_usage_report_parsing.py pair into focused
sub-modules so every Python file is <= 500 lines, satisfying
test_file_length.py. Install python-kasa into .venv (declared in
requirements but missing after the 3.13->3.14 venv upgrade),
fixing 8 failing smart_plug tests and restoring 100% coverage.
Also includes prior in-progress work from the working tree: the
wake_alarm Progress/View/Hardware field-grouping refactor,
brother_printer query module + tests, diet_guard foodbank/state/cli
updates, new shared coerce/logging_setup helpers, morning_routine
orchestrator tweaks, dwm window-manager config, gaming scripts, and
misc maintenance/digital-wellbeing script updates.

- install.sh: install sleep-hook.sh to systemd-sleep hooks (step 3) and
shutdown-wrapper.sh to /usr/local/bin/shutdown (step 5)
- shutdown-wrapper.sh: new script that intercepts shutdown calls and
redirects to rtcwake -m disk on alarm nights (Mon/Fri/Sat/Sun), pass-
through for reboots and cancel commands
- sleep-hook.sh: new systemd-sleep hook that restarts wake-alarm.service
for each logged-in user after hibernate resume
- setup_midnight_shutdown.sh: check wake-alarm day; if yes set RTC alarm
and hibernate, otherwise fall back to systemctl poweroff
- Screen locker: disable VT switching (Ctrl+Alt+Fn) via setxkbmap
srvrkeys:none on startup; restore on close (production mode only).
Gracefully skips if setxkbmap is not installed (shutil.which).
Tests: 7 new tests, 100% branch coverage maintained.
- Midnight shutdown: restore real schedule values (Mon-Wed 21:00,
Thu-Sun 22:00, morning end 05:00); re-enable the three commented-out
leniency checks in check_schedule_protection(); self-lock script with
chattr +i at end of enable_midnight_shutdown().
- Hosts install: add UNBLOCK_STATE_FILE tracking for whitelisted domains;
check_unblock_entries_protection() blocks installation if the unblock
list grows; save state after install; self-lock install.sh and
generate_hosts_file.sh with chattr +i.
- Move all linux_configuration scripts into two semantic categories:
- single_use/: scripts run once manually (fresh install, fixes, setup)
- periodic_background/: scripts run by systemd timers or daemons
- Preserve existing subdirectory structure within each category
- Fix lib/common.sh source paths for new directory depths
- Fix CONFIG_DIR depth in setup_periodic_system.sh and check_and_enable_services.sh
- Update all references in tests, fresh-install/main.sh, nix modules, and docs
- Fix check_polling_antipatterns.sh false positives (||, regex |, case patterns, jq strings)
- Fix pre-existing mypy exclusion path and type annotations for moved tools/ directory
- Rewrite check_polling_antipatterns.sh using awk (no bash regex loops); add require_serial: true
