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
