The forward-chain fix from 334c0cd9 only ever reached the live ruleset by
hand; /etc/nftables.conf kept the bare default-drop chain, so the next
reboot cut every bridged container off again and the Signal bot went deaf
a second time. Nothing compared generated against persisted.

The GTK tray icon was the only status surface, and it had been commented out
of ~/.config/i3/config since 2026-08-21. With nothing in the bar, the locker
miscounted the week for a fortnight and the machine never said so.
Shows "<count>/<minimum> · <gaming budget>", read from the local status API
(screen-locker-web.service on 127.0.0.1:8770); clicking opens the full UI.
Three things it deliberately will not do quietly:
- a dead status server renders "status server down" in red, or the last known
value marked (stale) in orange -- never a blank block. That server is what
the gaming budget reads, so its absence costs two hours;
- a disarmed or unscheduled timer overrides the compliance colour entirely
and shows "DISARMED" in red. A locker that cannot fire is the worse
problem and the one that hides;
- clicking only opens the UI. There is no bar action that can clear a lock.

`write_nftables_ruleset` emitted a forward chain with `policy drop` and no
rules at all. That chain runs at the same netfilter hook as Docker's own
DOCKER-USER/DOCKER-FORWARD chains, so it vetoed them: every bridged
container lost outbound networking while the host itself stayed online, so
nothing looked broken.
It cost the Signal bot three silent hours today. signal-cli lost its
connection to Signal at 15:32:50 and looped on reconnect for 2.5h, while
the bot kept answering /healthz with 200 -- `/v1/groups` still served from
local state, so every surface said healthy.
`flush ruleset` also deletes Docker's own tables, and dockerd only rebuilds
them on its next network event, so restore_docker_rules() now restarts
docker right after a successful apply.
Verified in vmbox (Arch guest, docker installed, alpine probe):
BASELINE=reachable -> OLD=blocked -> NEW=reachable, sshd active throughout.

Two failure modes compose cannot see, both of which report a healthy
container while it serves 404s:
1. The Caddyfile is a bind mount, so its contents are not in the config
hash compose compares. Editing it changes nothing observable, compose
says Running, and the new directives never load.
2. A bind mount resolves once, at start. Replacing dist/ rather than
emptying it leaves the container on the old unlinked inode: /srv reads
empty and every request 404s.
Hit both at once on a real deploy today -- the container was Up 6 hours,
Caddy logs clean, /srv empty, curl 404. Reproduced by rm -rf dist (inode
84695030 -> 84695031) and fixed by the patched function in one run.
wait_for_website also stops using curl -sf, which collapses every non-2xx
into the same "did not become reachable". It now reports the status it saw,
because unreachable and answering-404 are different bugs and the message
named only the first.

The personal-website repo now prerenders each post to
dist/blog/<slug>/index.html. Caddy try_files does not resolve a directory
to its index on its own, so with the single-term directive every post URL
fell through to the SPA shell: right content once React booted, wrong
<title>, and no link preview. Verified against caddy:2.8 in Docker both
ways before and after.

`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint
were still grading `meta/` against 3.10 -- three tools judging an interpreter
nothing runs any more, and ruff withholding the pyupgrade fixes that only
become safe at the newer target. `pin_ci_python.py` rewrites these three knobs.
What the stale target was hiding: `datetime.timezone.utc` where `datetime.UTC`
is now correct (UP017), and ruff's stable formatter applying PEP 758 --
`except (A, B):` becomes `except A, B:`. That makes the source 3.14-only at the
syntax level, which is what `requires-python = ">=3.14"` already promised; kuhy
chose it deliberately over holding ruff a release back (2026-08-29).
Also drops a comment in `wsg_grabber/models.py` that the bump makes false: it
explained why the file used ``str, Enum`` instead of ``StrEnum`` under mypy at
3.10, sitting directly above a ``class Verdict(StrEnum)`` that had already
stopped obeying it.
ruff, ruff-format, mypy --strict and pylint all clean at the new target.

Renames this repo's markdown onto README.md / CLAUDE*.md / DOCS*.md /
TODO*.md so a future session can tell a live task from a finished
record without reading the file to find out.
TODO files carry the literal "REMOVE ME AFTER FINISH" and are deleted
when the work lands. Enforced by the md-naming pre-commit hook and CI
workflow, both delegating to the shared gate in kuhyx/utils so this
repo's idea of a valid name cannot drift from every other repo's.

The previous commit made hosts-blocker's install.sh register the guard-lib
instances itself, which is what finally gives a fresh machine real hosts
enforcement. It also created a class of machine that --rollback refused to
touch: the state dir it demanded, /var/lib/guard-lib-migration, is written by
the one-shot migration, and a machine that never had a legacy layer has no
such state. So --rollback exited 1 while the instances it exists to remove
were live -- every freshly installed machine had no escape hatch at all.
Rollback now proceeds whenever a guard-lib instance is registered, says
plainly that there is no legacy layer to restore, and still refuses when
there is genuinely nothing to roll back.
The second half is worse and was only visible by running it. The existing
re-assertion of chattr +i works by starting hosts-guard.service and
hosts-bind-mount.service, neither of which exists on a fresh machine, so
every systemctl cat skipped and the rollback finished with /etc/hosts holding
no immutable flag and no bind mount -- less protected than before it ran.
It now re-asserts immutability directly when no legacy unit did it.
Verified in a pristine vmbox guest whose guards came from
install_core_system.sh --all: dry-run and real rollback both exit 0, the
three instances are uninstalled, shutdown-schedule (a different feature) is
untouched, and /etc/hosts keeps ----i----------------- and all 178410 lines.

Two of the seven modules invoked python_pkg/ paths that stopped existing when
screen_locker and steam_backlog_enforcer were extracted into their own repos,
so the first thing the installer did on a fresh machine was fail. Nothing
installed guard-lib either, which meant the CORE "Midnight shutdown timer"
module always died with "guardctl not found on PATH".
Every module now resolves through install_module_from_repo, and
require_extracted_repo clones a missing sibling instead of only printing
instructions -- otherwise "clone it yourself" is not actionable on the bare
machine this script exists to set up. The clone drops privileges to the
invoking human via sudo -u, because an installer that re-execs under sudo
would otherwise leave a root-owned checkout in the user's home; a sandbox
cannot catch that, since the guest is root throughout. A clone that fails is
still a loud, fatal module failure, never a silent skip.
guard-lib is addressed as the "utils" repo: it is a subdirectory of
github.com/kuhyx/utils, so asking for "guard-lib" would resolve to
~/guard-lib and derive a clone URL that does not exist. It installs first,
before the modules that need guardctl.
Separately, the security hardening suite's screen_locker section hardcoded
$HOME/testsAndMisc/python_pkg/screen_locker/screen_lock.py. That path went
away with the extraction, so all five checks silently SKIPPED -- reporting a
clean run for tests that never executed, which is the exact failure mode
lib/extracted_repos.sh was written to prevent. It resolves the repo properly
now ($HOME is also wrong under sudo), and the assertions are rewritten against
the current implementation: the four symbols they grepped for no longer exist
anywhere, having been replaced by SPORT_CHOICES, SPORT_TABLE_TENNIS,
_validate_table_tennis and MANUAL_WORKOUT_REFLECTION_MIN_CHARS.
On this host that takes the suite from 18 passed / 1 failed / 5 skipped to
23 passed / 0 skipped. The task file's "18 passed / 6 skipped out of 17"
target was stale -- the suite is 24 checks now -- so it could not be matched
literally.

The last unit over the cap is now github.com/kuhyx/digital-wellbeing, cloned
at ~/digital-wellbeing, and `--warn` is gone from the directory-depth-cap
hook. `check_directory_depth.sh --all` exits 0 with zero violations, down from
46 at the start of the session. That was the point of the campaign.
History was filtered across all three paths the unit has lived at (63
commits); the current path alone holds 2.
The six suites that test this code lived in linux_configuration/tests/ rather
than beside it, so they were filtered separately (24 commits) and merged in as
a second root. A path filter of the unit alone would have left them here,
testing code that had left the repo -- and their names would still have been
in shell-tests.yml's hardcoded arrays, failing CI on missing files.
linux_configuration/lib/common.sh is vendored into vendor/ rather than trimmed
to the four functions actually used: set_actual_user_vars calls two of the
others, so a trim breaks silently. It is in vendor/ and not lib/ because
test_music_parallelism.sh copies the unit's own lib/ into a scratch worktree
while stubbing the shared lib; in one directory the real common.sh overwrote
the stub, and the suite silently measured the wrong library.
Running the callers caught what shellcheck and grep both missed:
check_and_enable_services.sh died with "DW_REPO: unbound variable" because the
definition sat below its first use. It now runs clean and reports ok for every
extracted-unit check.
Two long-standing live defects fixed as a consequence. The pacman-wrapper
drift manifest embeds ABSOLUTE paths and had named deleted scripts/ paths
since the flatten, so the check reported a permanent false "stale or
tampered"; it now verifies, with unchanged hashes proving the extracted bytes
are identical. And the last two stale live references are gone: 8 -> 0.
The two pre-commit excludes for setup_midnight_shutdown.sh are dropped rather
than moved. lsattr shows nothing in the unit is chattr +i any more, and the
fixer hooks leave the file alone when allowed to run.
Removing 80 shell files also shrank the jscpd denominator enough that the
virtualenv/tqdm clones inside the GENERATED .ci-mirror-venv/ tipped the repo
to 2.09% and blocked this commit, which adds no duplication. That directory is
the same vendored third-party shell the ignore list already excludes as
.venv/, just under another name; jscpd walks the working tree rather than the
index, so being untracked did not spare it. Excluded by name: 1.74%.

Five live mechanisms were silently pointing at paths that no longer exist.
None of them announced it; each degraded to a log line or a missing file.
- hosts-file-monitor.service is ACTIVE and watches /etc/hosts for tampering,
but its embedded installer path was the pre-flatten scripts/ one. It logged
"Hosts install script not found" 37 times: it detected tampering it could
not repair.
- dns-blocklist-refresh.service (enabled, next run 00:01) named a deleted
single_use/features/ path, as did media-organizer.service under utils/.
- setup_periodic_system.sh read all TEN of its templates from
periodic_background/system-maintenance/, which has held nothing but
untracked .pyc and .coverage residue since system-maintenance was
extracted. Every install of a service, timer or script was reading a file
that was not there.
- /etc/sudoers.d/hosts-install-no-passwd granted NOPASSWD on the old hosts
installer path.
Running the fixed dns unit then caught a bug the static checks missed: under
systemd there is no SUDO_USER and `id -un` is root, so the new resolver
returned /root/hosts-blocker and the service died with "Feed generator not
found". extracted_repo_home() now handles the bare-root case by falling back
to the owner of the lib file itself. Verified across all four invocation
modes: as the user, via sudo, as root with SUDO_USER unset, and with an
explicit *_DIR override.
The service now reports "Feed refreshed and dnsmasq reloaded (189038 lines)".
/etc/hosts is untouched throughout -- still 176888 lines, still chattr +i,
still bind-mounted by its guard.
Live artifacts were patched via validated temp files, never in-place: the
sudoers drop-in was checked with `visudo -cf` before install, and every
original is backed up under /var/tmp/*.pre-{extract,fix}.
Stale live references: 8 -> 2. The 2 that remain name digital_wellbeing
paths and can only be fixed when that unit is extracted.

linux_configuration/periodic_background/hosts/ is now
github.com/kuhyx/hosts-blocker, cloned at ~/hosts-blocker. Clears 5 of the 46
directory-depth violations; the remaining 41 are all digital_wellbeing, so
--warn stays on the depth hook until that unit moves too.
History was filtered across ALL FOUR paths the unit has lived at (hosts/,
linux_configuration/hosts/, linux_configuration/scripts/periodic_background/
hosts/, and the current one). Filtering on the current path alone would have
preserved 1 commit out of 51 -- the flatten moved it recently, so a naive
single --path silently truncates the history to the flatten commit and still
looks fine in `git log | head`.
No source line changed: all 15 files are byte-identical to the copies removed
here. install.sh already resolved its lib/ via BASH_SOURCE.
The six callers now resolve the checkout through a new shared helper,
linux_configuration/lib/extracted_repos.sh, which reads the invoking user's
home from SUDO_USER's passwd entry rather than $HOME -- several of these
scripts re-exec under sudo, where $HOME is /root. A missing checkout fails
loudly with a clone instruction; it is never a silent skip, which is the
failure mode that left screen-locker's self-repair dead for five months after
the 2026-05-15 reorg.
The live blocker is untouched: /etc/hosts keeps its chattr +i, and the guards
load their plugins from /usr/local/share/guard-lib-plugins/ (byte-identical by
md5), not from a repo path.
Verified: 25 tests pass from ~/hosts-blocker; shellcheck clean on the helper
and all six callers; sudo resolution prints /home/kuhy/hosts-blocker;
test_setup_dns_blocker.sh passes; report_live_state.sh --check is byte-identical
before and after, so no new stale references.

Shell tests went red on my last push. test_network_diagnostics.bats sourced
its scripts through $REPO_DIR/scripts/diagnostics, a level the flatten
removed, so setup() failed and all 30 tests errored.
Latent rather than new: the previous run was green only because ci-mirror
aborted before the bats stage. Fixing the concurrency OOM let the gate reach
this suite for the first time since the flatten.
Grepped the tree for the removed scripts/ and single_use/ levels; this was
the last one in tracked code.
Also rewrites the two handoff docs around the units that remain.

The pre-push gate was failing on a layout that is actually correct. The
script sources ../../lib/common.sh, which is right for where it sits after
the flattening; the test's guard still hardcoded ../lib/common.sh from
before the move, so it reported drift against itself.
The prefix is now read out of the script under test, so the two cannot
desynchronise the next time the tree moves. Verified non-vacuous: rewriting
the script to ../../../lib/common.sh in a throwaway worktree still fails
the guard, and it now names the real prefix.

Both were non-conforming before this session and block every push, not

check_file_length.sh required a dot in the filename, so every
extensionless executable was silently uncapped. is_source_file() now
reads the first two bytes and accepts a shebang, which catches real
scripts while still skipping data files like i3/config.
That immediately surfaced boot_recovery/boot-repair at 756 lines --
three times the largest capped shell file in the repo, uncapped purely
because its name has no dot in it. Split along its own section markers
into lib/{discovery,repair_fs,repair_kernel,modes}.sh, leaving the entry
script at 218.
The report block stays inline on purpose. It is top-level code with exit
calls rather than function definitions, and sourcing it changed control
flow: 30 of 42 tests failed. That is recorded in the lib headers so the
next reader does not retry it.
No vmbox pass for this one, deliberately. boot-repair is UEFI/ESP tooling
and the guest is BIOS/GRUB, so a sandbox green would be actively
misleading -- the vmbox skill says so itself. The evidence is the fixture
suite, which drives the real script against synthetic root trees: 42
passed before, 42 passed after.
verify_shell_split.sh reports 31 of 32 functions byte-identical. The one
difference is clean_shadow_files, where quoting $ESP_MOUNTPOINT fixed a
genuine SC2086 that only became visible once the function left the
monolith -- shellcheck could no longer see the readonly declaration and
stopped assuming the expansion was safe.
lib/tests/run_all.sh delegates to that same suite rather than standing up
a second, weaker harness: these libraries need the entry script's strict
mode and globals, so testing them in isolation would test a fiction.

i3 config was filed under periodic_background, which it never was. It is
now linux_configuration/i3/ (config + installer) and
linux_configuration/i3blocks/ (the status scripts), both at depth 2.
misc/testsAndMisc-bash/ was a directory named after the repo it already
lived in, so its contents moved up to misc/. Its stray .gitignore came
along, keeping the media rules working from the new location; its
.vscode/tasks.json did not, because it invoked Bash/transcribe.sh, a path
this repo dropped long ago.
Most of this commit is the references the previous flatten missed. Its
regex skipped anything with a variable prefix, which left 16 files --
including check_and_enable_services.sh and install_core_system.sh, the
orchestrators -- still naming $CONFIG_DIR/scripts/periodic_background/...
It had also rewritten three i3 paths into scripts/i3blocks/, a directory
that has never existed; the i3blocks suites caught that by failing.
13 more symlinks broke on the i3 move. Repointed, and cpu_monitor/volume/
disk were run again to confirm the bar still reports.
Depth 139 -> 104. Roughly 47 of the remainder sit in digital_wellbeing
and hosts, still deferred. The rest encode real structure -- a C project,
Python package directories, artgate's routes/styles, systemd unit dirs --
so flattening them further would destroy information rather than
taxonomy.
Verified: 1798 tests at 100%, both i3blocks suites pass, the shell
coverage gate is clean, and the relocated media rules still ignore what
they should while test_fw.srt stays tracked.

Two levels of pure taxonomy carrying no information, and a 2-directory
cap leaves no room for them. Categories now sit directly under
linux_configuration/: features, fixes, utils, misc, fresh-install,
installers, diagnostics, gaming, boot_recovery, periodic_background, lib,
meta, tests. A script's own lib/ and tests/ are exempt from the cap, so
those stay put.
Depth violations 248 -> 139; roughly 40 of the remainder are inside
digital_wellbeing and hosts, deferred until the guard-lib repoint.
The moves are the easy half. What breaks is every path that counted
levels, and three classes of it had to be found by resolving paths rather
than reading diffs:
- 52 relative `source` lines for lib/common.sh and lib/android.sh. The
correct prefix differs per file: 40 were ../../ and 12 were ../../../,
so a blanket replace would have fixed one set and broken the other.
- REPO_ROOT in 7 fixes/lib/tests harnesses and setup_syncyomi_guard.sh,
each walking up four levels from a directory now two levels shallower.
This caused a real regression -- the fixes suite went red with
"log_warn: command not found" -- caught by running it and comparing
against the pre-move baseline worktree.
- conftest.py's sys.path entries, which took the pytest gate down with
14 collection errors, and the `# shellcheck source=` directives, which
took shellcheck down with SC1091.
16 symlinks in $HOME broke, including the entire i3blocks bar. All
repointed, and cpu_monitor/memory/disk/time/volume were run to confirm
they emit real output rather than merely resolving.
Verified: 1798 tests pass at 100% coverage, 8 of 9 lib/tests suites pass
(the ninth needs the coverage jail, identically at baseline), pre-commit
is clean, and the two untracked secret configs are still ignored after
their gitignore paths changed.

github.com/kuhyx/phone-focus-mode
The two halves go as one repo: focus_policy parses phone_focus_mode's
config.sh into the typed policy that focus-owner consumes, and nothing
else references it. 77 commits of history, plus the two Python suites
from linux_configuration/tests/ and the six mutation fixtures from
meta/scripts/fixtures/, all of which named phone_focus_mode paths.
Running the suites -- not reading them -- turned up a real defect the
extraction would otherwise have inherited. config.sh sources the
untracked config_secrets.sh, and ctl_libs_harness.sh never pinned
HOME_LAT/HOME_LON, so the distance assertions were checking against
whatever real coordinates that file happened to hold. The suite passed on
this machine and could not run anywhere else, and a real home location
was load-bearing in a pass/fail condition. The harness now pins a pair
4300 m south of the coordinate its own case seeds, and config.sh sources
the secrets file only when it exists. 136/136 pass with no secrets file
present.
Before making the repo public I scanned the whole history for the known
home coordinates and for any committed config_secrets.sh: zero hits, and
the file was never tracked. The new repo also gained a .gitignore, since
none came across in the filter-repo pass.
test_magisk_service.sh hangs. It hangs identically in the pre-extraction
baseline worktree and appears in no CI list here, so the new repo's CI
skips it with that reason rather than pretending it passes.
check_python_location.sh loses its phone_focus_mode exception now that
the directory is gone; every tracked .py still passes it. The .gitignore
rules for config_secrets.sh and the keystore STAY -- the working copy is
still on this machine and still holds a real location.
Depth 262 -> 248.

github.com/kuhyx/android-guardian, cloned to ~/android-guardian
periodic_background/utils/ held two unrelated things: the Magisk module
and heavy_job_lock.sh. Only the module was a unit, so the directory is
split rather than moved.
heavy_job_lock.sh goes to digital_wellbeing/, NOT to ~/utils. Measured
rather than assumed: of its consumers only install_pacman_wrapper.sh
reads the repo copy, while pacman_wrapper.sh, makepkg_capped.sh and
meta/scripts/run_with_heavy_lock.sh all read the installed
/usr/local/bin copy. A library belongs with whoever installs it, and
exporting it would have added a cross-repo edge for one caller.
Fixed a bug that predates the extraction: update_android_hosts.sh set
GUARDIAN_MODULE_DIR to "$SCRIPT_DIR/android_guardian", a sibling that
never existed at that path -- packaging could not have worked from this
checkout at all. It now reads ${ANDROID_GUARDIAN_DIR:-~/android-guardian}
and require_guardian_module() gates build_module(), the single funnel
every packaging path goes through, so a missing checkout names the clone
command instead of failing inside a cp four helpers deep.
Verified both directions: with no checkout the guard fires with
instructions; with one, the module builds -- 182331 blocked domains, a
1.1 MB zip. The subsequent adb push failed on device-side storage, which
this commit does not touch.

github.com/kuhyx/system-maintenance, cloned to ~/system-maintenance
First of the four live subsystems, and the one with no cross-unit source
edges, so it establishes the pattern for the harder three. Passed in
vmbox first -- the installer ran from an extracted-layout copy in the
guest and detected its distro without any monorepo path -- then on the
host.
Its 21 Python and shell test files lived in linux_configuration/tests/,
reaching bin/ through a shared conftest. Twenty moved with the code and
got their own conftest; the shared one stays, since it serves several
script directories that are not going anywhere.
test_shutdown_timer_monitor.sh stays here. It is a pair test: it checks
that digital_wellbeing's installer template and the monitor it installs
still agree, so it belongs to whichever half owns the installer. It now
reads the monitor from ~/system-maintenance and SKIPs when that checkout
is absent.
An intermediate version of that test fell back to /usr/local/bin, which
HUNG -- the installed copy is stale and differs from source, so the test
was comparing an installer template against a binary it never generated.
Falling back to it would have been worse than skipping, so the fallback
is gone and the comment says why.
Also removed test_hosts_file_monitor.sh from shell-tests.yml's explicit
list: it left with the subsystem, and CI would have failed on the missing
file rather than quietly skipping it.
Verified: 136 tests pass in the new repo, 202 still pass here, the pair
test passes against the checkout and skips without it, and both the shell
coverage gate and shellcheck are clean. Depth 294 -> 267.

github.com/kuhyx/mtk-root
Unlike the app extractions, mtk_root could not travel alone: its four
libraries and three of its four test suites sat in scripts/lib/, one
directory up from the stages that source them. Taking only the directory
would have orphaned eight files here and left the new repo unable to
source anything, so all twelve moved in one filter-repo pass. The
mtk_root/ + lib/ sibling layout is preserved, so every
`source "$SCRIPT_DIR/../lib/..."` resolves with no call site edited.
Two things the new repo needed that the monorepo provided implicitly:
lib/tests/run_all.sh -- the copy here is shared with the non-mtk suite
and stays. Without a new one, shell-tests.yml's
glob over */lib/tests/run_all.sh would have
stopped covering these suites on a green build.
.shellcheckrc -- external-sources + source-path=SCRIPTDIR, which
is what lets shellcheck run with no severity
filter and still pass on the ../lib/ sources.
mtk_harness.sh stays here despite the name: test_common_datetime.sh
sources it. Removing it broke that suite outright, which running the
suite caught immediately. Its header now describes what it actually
serves; the misleading name is kept on purpose, since renaming would
churn its one consumer for nothing.
Verified: 84 tests pass in the new repo with shellcheck clean, 55 still
pass here, and check_shell_coverage.sh --all exits 0 with the four
mtk_root allowlist entries gone.

Three self-contained apps move to their own public repos with full
history (8, 14 and 30 commits, each matching the monorepo count):
github.com/kuhyx/reverse-survivors
github.com/kuhyx/kcd2-dice-solver (cloned to ~/kcd2-dice-solver)
github.com/kuhyx/focus-owner
Each gained a CI workflow. Only reverse_survivors had one here; the other
two were never gated by anything, which is part of why they no longer
belong in a repo whose CI is shared.
What stayed: setup_kcd2_dice_solver.sh, which deploys the solver rather
than being part of it. It now builds from ~/kcd2-dice-solver, and the
post-commit hook it generates drops its `git diff -- kcd2_dice_solver/`
filter -- in a standalone repo every commit is solver code, so the old
filter could never match again.
focus_owner's two references to python_pkg.focus_policy now name the
phone-focus-mode repo, where that generator is headed.
Running the live kcd2 unit -- rather than reading it -- found three real
breakages that no amount of grepping would have: pnpm ignoring the
package.json "pnpm" field, pnpm refusing to purge node_modules without a
TTY, and the Docker container still bind-mounting the deleted monorepo
path. All three are fixed; the unit exits 0 and
https://dice.kuhy.duckdns.org/ serves the freshly built bundle.
Depth violations 417 -> 303.

Three changes, none of which touch what a single test asserts:
thorium_repairs.sh's `sleep 4` becomes `sleep ${THORIUM_STARTUP_WAIT:-4}`
and the harness sets 0.2s. Three cases were each paying four real
seconds to watch a stubbed browser stay up; the stub sleeps 30s, so the
`kill -0` check is unchanged. That file: 17.0s -> 5.6s.
_t_hide was the rest of it. It walks PATH and creates a symlink per
executable -- ~13.5k here, 4.6s a build -- and the suite has ~16
distinct tool sets. Now the full farm is built ONCE and `cp -al`
hard-links it per set, with only the hidden names deleted from the copy.
The cache also moved out of $TEST_TMPDIR, which is per-file, into a
run-scoped dir run_all.sh creates and removes, so it survives between
files.
110s -> 98s (sleep) -> 85s (shared cache) -> 37s (hard-linked farm).
645 OK, 0 FAIL throughout. The cases that only pass when a tool is
genuinely unfindable -- install_pyroveil's missing-dependency arms,
fix_aggressive without sqlite3 -- still pass, which is what proves the
farm is still hiding rather than quietly returning a full PATH.
lib_test_core.sh hit exactly 250 lines, so _t_hide and the farm move to
lib_test_path.sh (194 + 67).

The seams were applied, verified and measured, but never reached the
commit: cb1e8c53 shipped the file with its hardcoded /etc/X11,
/etc/profile and /home/$SUDO_USER paths. ci-mirror caught it by running
the suite from a clean checkout, where the tests read the REAL system
files -- the RenderAccel assertion failed against this machine's actual
xorg config, which says "disabled", and the pyroveil clone path came
back as /home/testuser rather than the tmpdir.
The local run passed only because a stale seamed copy was sitting in the
measurement worktree. Re-applied and grepped back immediately, which is
the documented rule for exactly this failure mode.

76/76 lines through run_all.sh at --min 100, exit 0. 45 assertions over
15 cases across all four functions.
XORG_CONF and XORG_CONF_D are plain globals ASSIGNED inside
configure_xorg, so the default had to move to the assignment itself --
exporting a value from the harness alone would have been overwritten on
entry. PROFILE_FILE and USER_HOME take the ordinary `${VAR:-default}`
form. The real /etc/X11/xorg.conf.d/20-nvidia.conf keeps its Jun 2025
mtime and ~/pyroveil does not exist after the suite runs.
configure_xorg's RenderAccel value is asserted to be "true" AND asserted
never to be "false": the lib's own comment records that "false" forces
software rendering and pins Xorg above 30% CPU, so that is a regression
worth a dedicated negative assertion.
install_pyroveil's prompt could not be asserted on its text -- bash
writes a `read -p` prompt straight to the terminal, so it never reaches
captured output. The branches are distinguished by the non-interactive
arm's "Auto-installing" line instead, which is observable.
bt_audio.sh re-measured at 127/127 with the new files present.
That is all eight libs from the original handoff: arch_sysctl (banked as
unmeasurable and quarantined), arch_cpu, arch_hardware, thorium_repairs,
hosts_guard_migrate, hosts_guard_rollback, ubuntu_perf_fixes and
nvidia_config. Allowlist 91 -> 84.

81/81 lines through run_all.sh at --min 100, exit 0, and
check_shell_coverage.sh passes with the allowlist line already deleted.
59 assertions over 14 cases across all four functions: the sysctl
drop-in with both the "already applied" skip and the documented-default
fallback for an unreadable sysctl; both NVIDIA branches, since the
helper-service path and the standalone fallback write different units
and different undo lines; earlyoom install / already-installed /
config-backup; and fix_failed_sssd for none, all five and exactly one
failed unit -- that last one matters because the detection loop breaks
at the first failure while the masking loop re-checks each unit, so a
naive implementation would mask all five.
The four write targets are now behind overrides defaulting to the real
paths. The add_undo lines deliberately KEEP their literal /etc paths and
are asserted to: the undo script runs on the real system, so seaming
those would have written an undo that removes nothing. Neither
/etc/sysctl.d/99-performance-tuning.conf nor /etc/default/earlyoom
exists after the suite runs.
bt_audio.sh re-measured at 127/127 with the new files present -- that
canary runs after every addition to this suite now, because a test file
silently broke it once already.
The handoff is rewritten for the one remaining lib.

hosts_guard_migrate.sh 81/81 and hosts_guard_rollback.sh 65/65, both
100.00% through run_all.sh at --min 100, and check_shell_coverage.sh
passes with each allowlist line already deleted.
82 assertions over 36 cases in three files sharing one harness: all four
validate_requirements refusals, plugin installation, the mount-collapse
loop in every arm (clears, fails, hits its 20-iteration bound, dry-run),
per-instance migration for both the bind-mounted and the plugin flavour,
and do_migrate's refusal to retire the legacy pacman hooks when nothing
registered -- the arm that exists so a failed migration cannot leave the
files with no unlock hook at all.
INSTRUMENT FIX: rollback measured 97.01% with lines 69 and 108
uncovered, both `done <redirect>` closing a loop. Reproduced minimally:
in a three-iteration loop ending `done >"$1"`, the body reports hits=3
and the `done` line hits=0, because bash attributes the redirected
compound statement to the loop's OPENING line. That is the same defect
_CLOSING_BRACE_OP already handles for `} |`, so _LOOP_END_OP is its
twin. The redirect is required by the pattern: a bare `done` stays in
the denominator, so genuinely uncovered loops are still caught.
Audited as the instrument notes demand -- every newly excluded line
printed with its text -- and it is exactly those two lines across all of
fixes/lib. Acceptance pair unchanged and exact: dot_resolver_install.sh
39/39, rpi_nc_ca.sh 73/73.

75/75 lines through run_all.sh at --min 100, exit 0, and
check_shell_coverage.sh passes with the allowlist line already deleted
so the pass cannot come from the exemption.
55 assertions over 23 cases: all five profile repairs plus test_thorium,
including every dry-run arm, the partial singleton-lock case, a corrupt
database and the sqlite3-absent path. The lib needed NO production
change -- it already takes every path from $THORIUM_CONFIG_DIR, so
pointing that one variable at the tmpdir confines it completely.
The gate's per-case timeout moves from the jail's 120s default to 600s.
That default is a hang-catcher, not a performance budget, and this suite
has outgrown it: 76s bare at 25 test files, 93s at 27, and kcov roughly
doubles it. The symptom was a lib FAILING the gate while measuring
perfectly -- bt_audio.sh printed "127/127 lines = 100.00%" and then
"warn: case timed out after 120s", which --fail-on-case-error turned
into a non-zero exit. bt_audio.sh and arch_cpu.sh both pass now.
The cost, recorded in the evidence: a genuine hang takes 10 minutes per
pass to surface instead of 2. test_thorium's `read -r -p` is exactly
that shape, so every case here feeds it stdin explicitly.
This also settles the quarantine in b2779059. Re-adding the arch_sysctl
cases still yields "kcov instrumented no lines" for bt_audio at a 600s
timeout with no timeout warning, so runtime was never that file's
problem and the quarantine stands for the reason its header gives.

check_shell_coverage.sh was RED on main. bt_audio.sh is off the
allowlist at 127/127, and commit 7c14cfca -- which added
test_arch_sysctl.sh -- made kcov stop registering it entirely, so the
gate failed on a lib nothing had touched.
Bisected by measuring bt_audio.sh at three commits: a2b23521 127/127,
afe6ac3a 127/127, 7c14cfca "kcov instrumented no lines". Removing that
one test file restores 127/127 with every other new file still in the
suite (arch_cpu, arch_hardware x2, thorium x2), and arch_cpu.sh
re-measures at 57/57 alongside it.
Both plausible causes inside lib_test_core.sh were ruled out by
reverting each on its own in a throwaway worktree: `export out` and the
_t_hide farm cache each left bt_audio broken while the file was
present. Neutering the file's body while keeping the source line does
NOT reproduce it either, so the trigger is cumulative rather than one
construct, and it is not understood.
The file keeps all 23 assertions and still passes when run directly; it
just leaves the test_*.sh glob run_all.sh iterates. That costs nothing
measurable, because arch_sysctl.sh has never measured through the jail
in the first place -- it reports "instrumented no lines" on its own,
like nc_php.sh -- and it stays on the allowlist.
The header records the bisect and what to re-verify before anyone
un-quarantines it.

clean_shadow_files() assumed UEFI with an ESP mounted at /boot. On a
BIOS/GRUB system with no ESP, /boot is a plain directory on the root
filesystem holding the only kernel the machine has -- and neither existing
guard catches it: findmnt /boot is empty (GUARD 1 passes) and there is no
EFI/ or loader/ (GUARD 2 passes). boot-repair therefore read the real
vmlinuz-linux and initramfs-linux.img as "orphaned kernel file(s)
shadowing the ESP" and deleted them, leaving the machine unbootable.
Measured 2026-08-22 in a vmbox BIOS/GRUB sandbox, not theorised: after
sudo boot-repair the guest never booted again.
GUARD 3: if /sys/firmware/efi does not exist the system booted via BIOS,
so there is no ESP and nothing in /boot can be a shadow. warn + return 1,
matching the existing guards' tone and exit convention. Overridable with
the existing --esp DEVICE -- naming the ESP by hand asserts the firmware
assumption the guard otherwise checks -- rather than adding a new flag.
The check goes through rpath(), so a --root fixture declares its own
firmware type and the case is testable without a VM. On the live UEFI
machine it resolves to the real /sys path, so behaviour there is unchanged.
Audit of the other BIOS-unsafe paths (none destructive, left alone):
* mount_esp(): resolve_esp_device fails with no /boot fstab entry, so it
reports and does not mount. Non-destructive.
* sync_kernel_image()/rebuild_initramfs(): gated behind boot_is_mounted,
which is false on BIOS, so they never write.
* check_fstab_options(): reports "no /boot entry" -- noise on BIOS, but
it writes nothing.
* run_preflight(): aborts every kernel upgrade on a BIOS box. Fail-closed
and non-destructive, so out of scope here.
Tests: three cases in tests/lib/boot_repair_bios_cases.sh (new file; the
existing case lib is at the 250-line cap) -- the guard refuses and explains,
--esp overrides it, and a UEFI fixture still cleans shadows as before.
Verified failing without the guard (38/4) and passing with it (42/0).
Sandbox: BIOS guest keeps both kernel files, says why, and still boots
afterwards (uname -r 7.1.9-arch1-2 after a clean poweroff). shellcheck clean.

94/94 lines through run_all.sh at --min 100, exit 0. 42 assertions over
26 cases across all five functions, including both boot-loader flavours
and the no-boot-loader path.
PRODUCTION BUG, found by writing the tests and confirmed against this
host: tweak_journal's regex required a space before the unit, but
journalctl prints "305.5M in the file system" with no separator. The
size check never matched, so the vacuum was unreachable and a
multi-gigabyte journal would never have been trimmed. This is the third
instance of the same defect -- arch_perf_report.sh:36,65 carried it too
-- so the fix is identical: the separator is now optional. One case
asserts the spaced form still matches, making this a widening.
The mitigation tweak edits the boot loader, so /boot/loader/entries,
/etc/default/grub and grub.cfg are now behind overrides defaulting to
the real paths. This machine's boot configuration is never touched.
_t_hide gets a cache: it symlinks every executable on PATH (13.5k here)
and was rebuilding that farm on every call, which took the suite to 92s
and pushed a jail case past its 120s timeout. Now 77s, and arch_cpu.sh
re-measures at 57/57 so the shared change cost nothing.
The cases are split across two files because a single one was 307 lines
and file-length-cap rejected the first commit attempt.

57/57 lines, measured through run_all.sh and confirmed a second time at
--min 100 so a shortfall would exit non-zero. check_shell_coverage.sh
passes with the exemption removed.
28 assertions over 14 cases: no cpufreq at all, every core already
tuned, the mixed case where only some cores lag, cpupower absent /
unconfigured / already configured, and all three I/O scheduler targets
(none for NVMe, mq-deadline for SATA SSD, bfq for spinning disks).
The sysfs reads and the two /etc write targets are now behind overrides
defaulting to the real paths, so the tests can present hardware this
host does not have -- a rotational disk -- without touching anything.
One assertion initially passed for the wrong reason: _t_hide keeps
$FAKE_BIN on PATH by design, so the harness's own cpupower stub still
satisfied has_cmd and the "not installed" branch never ran. Unstubbing
before hiding is now explicit, and the case fails if that is lost.
This also settles arch_sysctl.sh's diagnosis: it uses this same
harness, so the harness is not why it cannot be measured.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
23 assertions over 8 cases covering both tweak_vm_sysctl and
tweak_network_sysctl: the skip path, the write-when-the-drop-in-is-
missing path that a naive "nothing to do" check gets wrong, the
value-differs path, an unreadable-sysctl path, and the tcp_bbr guard.
arch_desktop_harness.sh is the third family harness, supplying the
globals and apply_tweak that live in optimize_arch_desktop.sh rather
than in any lib. arch_cpu.sh and arch_hardware.sh will reuse it.
SYSCTL_DROPIN_DIR defaults to the real /etc/sysctl.d, matching the
seam ubuntu_perf_more.sh and arch_perf_fixes.sh already carry; the
suite runs un-jailed in ci_mirror.sh and CI, so a bind mount would
protect nothing. Both real drop-ins keep their Mar 2 mtimes.
_t_run lands in lib_test_core.sh because `out="$(func)"` forks a
subshell and kcov never registers a lib whose first execution happens
inside one -- measured as 0 lines via $( ) against 54 lines via a
direct call.
arch_sysctl.sh STAYS on the coverage allowlist: it still reports "kcov
instrumented no lines" through the jail, while ubuntu_perf_more.sh
measures 32/32 in the same worktree and the same invocation. The tests
are real and green; the coverage number is not yet obtainable, and the
exemption may only come off once it is.

shfmt runs on every staged shell file and rewrites drifted libs, which
moves coverage denominators and invalidates measurements taken minutes
earlier. Landing the reformat first makes every number measured from
here the number that survives pre-commit.
thorium_repairs.sh converts from 2-space indent to tabs; the other two
only lose runs of blank lines. `git diff -w` shows no token changed,
shellcheck is clean, and the 20-file suite stays green.

Eighth of the 16 untested fixes/lib libs. 22 assertions; 43/46 = 93.48%. The
lib STAYS on the allowlist -- see the artifact below.
Third instance of the same dead branch. Line 16 matched on
`([0-9]+\.?[0-9]*)\ G`, a required space before the unit, while journalctl
prints "4.2G" with no separator, so the vacuum could never run. Fixed to an
optional space, as in arch_perf_report.sh.
This one differs from that earlier fix and the difference was confirmed with
the user before landing: arch_perf_report.sh's vacuum sits behind
--apply-safe-fixes, but THIS one runs whenever fix_arch_performance.sh runs.
So the fix makes an unflagged destructive action live -- the script will now
really vacuum the journal to 300M once it passes a gigabyte. That is the
function's evident intent, since its next act is to write a permanent 300M
cap, and the user approved it explicitly.
Three absolute paths moved behind overrides defaulting to the real ones:
JOURNALD_CONF_DIR, SYSTEMD_UNIT_DIR (fix_media_organizer writes
/etc/systemd/system/media-organizer.service) and ORGANIZE_SCRIPT_CANDIDATES.
Verified afterwards that the real unit file still carries its 2026-07-25
mtime and the journald drop-in its 2026-03-02 one, i.e. a bare un-jailed
run_all.sh touched neither.
The three uncovered lines (68-70) are the element lines of a multi-line array
literal. `PS4` + `set -x` on a minimal case shows bash reporting the whole
assignment at its OPENING line and never emitting the elements or the closing
paren, so they are data, not statements -- a fourth flavour of defect (a),
after multi-line quotes, `} |` and the backslash-continued assignment. The
array is provably used: the loop on the next line iterates it and the
media-organizer assertions pass.
Worth fixing, unlike the bt_adapter one-liner: the form appears in three of
the remaining untested libs (thorium_repairs.sh has four) and in nine
allowlisted libs repo-wide. That lands as its own commit next.

Seventh of the 16 untested fixes/lib libs and the first of the ubuntu-perf
pair, which gets its own harness here. 24 assertions; 32/32 = 100.00%
through run_all.sh on the first measurement, confirmed at --min 100 (exit 0),
then cleared with the real gate and no exemption.
Two absolute paths had to move behind env overrides, defaulting to the real
ones: fix_journal writes /etc/systemd/journald.conf.d/size-limit.conf and
run_undo globs /root for undo scripts. Binding those in the jail was rejected
for the same reason as bt_pairing.sh's udev rule -- run_all.sh runs UN-jailed
in ci_mirror.sh and in CI, so a bind mount protects the coverage run and
nothing else. JOURNALD_CONF_DIR and UNDO_DIR follow the UDEV_RULES_DIR
precedent.
Proof the suite is safe where it runs un-jailed: after a bare run_all.sh the
real /etc/systemd/journald.conf.d/size-limit.conf still carries its 2026-03-02
mtime, a genuine artifact of a past production run, and no
undo_ubuntu_performance_*.sh exists in /root.
Worth noting for the rest of the family: run_undo ends in `exit`, so its cases
run inside an explicit subshell. A command substitution already provides one,
so the exit ends only that subshell rather than the whole test file.

Sixth of the 16 untested fixes/lib libs, and the first with no dead branch to
fix -- the whole job was test-writing. 43 assertions across two files;
93/93 = 100.00% through run_all.sh, twice, the second at --min 100 (exit 0),
then cleared with the real gate confirming and no exemption.
The one genuine gap was check_memory_pressure's high-swap branch (lines
158-159), which fires only when swap is heavily used WHILE RAM is still
available -- a state this host does not happen to be in. The lib reads the
absolute /proc/meminfo, but every read goes through `awk`, so stubbing awk
supplies controlled figures without touching /proc: the stub answers on the
pattern being matched and execs the real awk for anything else. Both
directions are covered, including RAM genuinely exhausted, which must NOT be
flagged because it is not the stutter signature.
Everything else here is branch coverage of probes whose inputs are external
commands: failed systemd units, ACPI error counts, a CPU-hungry Xorg,
governors all-performance vs one-powersave vs unsupported, thermal
throttling excerpts, the TLP/power-profiles-daemon conflict in all three
combinations, and storage health with and without fstrim/smartctl.
lib_test_core.sh gains _t_stub_cat. "Print this fixture file" is by far the
commonest stub shape, and writing it inline forces every call site to embed
a literal ${LIB_TEST_DEV} that must not expand at write time -- SC2016 on
every use. Passing the fixture NAME as data removes the class outright, and
two earlier bluetooth test files are simplified onto it. All 21 test files
and three harnesses now lint clean with no suppression anywhere.

Fifth of the 16 untested fixes/lib libs and the first of the arch-performance
group, which gets its own harness here. 38 assertions across two files. The
lib STAYS on the allowlist at 59/60 = 98.33%, measured twice.
The second dead branch this campaign has found, fixed here. Lines 36 and 65
matched on:
([0-9]+\.?[0-9]*)\ (G|M)
a REQUIRED space before the unit. journalctl actually prints "Archived and
active journals take up 305.5M in the file system." with no separator --
verified against the real binary on this machine. So check_journal_size could
never report a large journal and apply_safe_fixes could never vacuum one:
both were unreachable. The space is now optional, and tests cover the spaced
and unspaced forms so neither can rot.
NOTE: this makes a previously-dead DESTRUCTIVE action live. With
--apply-safe-fixes and a journal over a gigabyte, the entry script will now
really run `journalctl --vacuum-size=300M`. That is the flag's documented
purpose and it stays behind the flag, but it has never actually executed
before today.
Line 20, the one uncovered line, is `} >>"$REPORT_FILE"` -- the closing brace
of a redirected group. A minimal probe writes both inner lines to the file
while bash attributes no statement to the brace, and the report assertions
independently prove the group runs, since they read the text it writes. Same
defect (a) class as bt_audio's `} |`.
That form now caps four libs: bt_audio.sh, arch_perf_report.sh, and
arch_perf_probes.sh and nvidia_config.sh which are still untested. So the
continuation_lines() fix is worth landing after all -- as its own commit,
next, so a denominator change can be reverted without taking these tests
with it.
_t_hide and _t_full_path move from bt_harness.sh into lib_test_core.sh: they
are generic PATH plumbing and the arch harness needs them for the
"nvidia-smi is not installed" branch. All twelve existing suites re-run green
after the move.
One trap worth recording: apply_safe_fixes appends to the ACTIONS array, so
it must be called directly rather than inside "$(...)" -- a command
substitution runs it in a subshell where the appends die with it, and the
assertions read an empty array.

Fourth of the 16 untested fixes/lib libs, the largest at 214 lines, and the
last of the bluetooth family. 47 assertions across three files. The lib
STAYS on the allowlist: 128/132 = 96.97%, twice with the same line set.
The bug the tests found, fixed here. Line 21 read:
if timeout 3 _run_as_user wpctl status &>/dev/null; then
`timeout` is a binary and `_run_as_user` is a shell function that is never
exported, so this always failed with rc=127 -- "timeout: failed to run
command '_run_as_user'". check_pipewire_health therefore reported PipeWire
hung on EVERY run and restarted a healthy audio stack every time
fix_bluetooth.sh ran. The healthy branch was unreachable, which is why the
test for it could not be written without first noticing. Now
`_run_as_user timeout 3 wpctl status`: same bound, inside the sudo'd command.
Why 96.97% and not 100%. An earlier run of this suite read 99/99 = 100.00%,
and that number was wrong -- it measured the file before pre-commit's
`shfmt -w` reformatted it. shfmt rewrites the `{ ...; } \` + `| bluetoothctl`
one-liners into multi-line blocks ending in `} |`, which raises the
denominator 99 -> 132. Confirmed unavoidable by running shfmt against HEAD's
own copy: it rewrites there too, so reverting the reformat is not stable.
The four uncovered lines (90, 113, 137, 157) are each that `} |` -- the pipe
operator joining a block to bluetoothctl, not a statement. They do execute:
a `{ echo a; echo b; } | consumer` block writes every marker to a file even
though bash's xtrace never reports the left-hand side, because a pipe's LHS
runs in a subshell whose xtrace is not captured. kcov instruments them and
cannot attribute them; defect (a) in docs/kcov-under-report.md, third flavour.
Scope, measured: the continuation-pipe form appears ONLY in bt_adapter.sh
(pre-format) and bt_audio.sh (post-shfmt). None of the remaining twelve
untested libs carries either, so this does not block the campaign and the
detector fix stays off the critical path.
Also worth 90.91% -> 96.97% on its own: the bluetoothctl stubs now drain
stdin before exiting. Real bluetoothctl consumes its whole input; a stub
that read one line and exited closed the pipe early, so the writing block
took SIGPIPE partway through and its later lines never ran.
NOTE for whoever edits this file next: bt_audio.sh is now exactly 250 lines,
at the cap. The next change to it needs a split, not a comment trim.

Third of the 16 untested fixes/lib libs, and the first that does NOT come
off the allowlist. 68/69 = 98.55%, up from 45/69. The remaining line is
not a missing test:
PS4='+TRACE:${BASH_SOURCE##*/}:${LINENO} ' bash -x
shows bash attributing the whole multi-line dbus-send assignment in
_services_resolved to line 100, and never emitting line 97 at all. Line 97
is the OPENING line of a backslash-continued statement; kcov instruments
it, bash never attributes a statement to it. That is defect (a) in
docs/kcov-under-report.md -- a wrong denominator -- and no test can move it.
continuation_lines() in shell_coverage_lines.py already excludes such lines,
but only detects them by tracking QUOTE state, so a line ending in an
unquoted backslash slips through. Fixing that is deliberately left out of
this commit: it changes the denominator for every measured lib, and if it
regresses one of the libs now gated with no exemption, reverting a mixed
commit would throw away these tests too.
Scope of the problem, measured rather than guessed -- backslash
continuations are confined to the bluetooth family: bt_audio.sh 10,
bt_adapter.sh 7, bt_pairing.sh 3, pacman_hook_stall_summary.sh 2, and ZERO
in the other 12 remaining libs. So this caps bt_audio.sh next and then stops
mattering.
Also replaces the harness's _t_only_path with _t_hide. _t_only_path dropped
PATH to $FAKE_BIN alone, which hid grep, head and sort as well as the tool
under test -- so the "usbreset is not installed" case died in a cascade of
"command not found" and passed for the wrong reason instead of exercising
the fallback. _t_hide rebuilds PATH from symlinks to every real executable
except the named ones; verified directly that command -v usbreset is then
empty while grep and head still resolve.
bt_report.sh (37/37) and bt_pairing.sh (65/65) re-measured at --min 100,
both exit 0, so neither cleared lib regressed.

Second of the 16 untested fixes/lib libs. 65/65 = 100.00% through
run_all.sh, twice, the second at --min 100 (exit 0), then cleared from the
allowlist and confirmed by the real gate with no exemption.
Two findings worth keeping:
- udevadm was NOT in the harness's stub list, so `udevadm control
--reload-rules` was reaching the REAL binary during the suite. A
prepended stub dir cannot hide a tool the host actually has. Caught by
asserting on the recorded call rather than by reading the code, which is
the argument for asserting on calls at all.
- _disable_usb_autosuspend writes /etc/udev/rules.d/50-bluetooth-no-
autosuspend.rules. Binding /etc in the jail would have covered it, and
was rejected: run_all.sh runs UN-jailed in ci_mirror.sh and in the
shell-tests workflow, as its own header says, so a bind mount protects
the coverage run and leaves every bare run writing to a real root-owned
file. Instead the lib gained a UDEV_RULES_DIR override, defaulting to the
real path -- the same env-override seam pacman_hook_stall_harness.sh uses
for PACMAN_LOG/CACHE_DIR/PACMAN_LOCK.
Proof the suite is safe where it runs un-jailed: after a bare run_all.sh,
the real rule file still has its 2026-02-21 mtime (it is a genuine artifact
of a production run six months ago) and the probed power/control values are
unchanged. The jail cannot give that check.
fix_usb_autosuspend globs the real /sys/bus/usb/devices/*/ with no override,
so its branches are driven through stubbed lsusb output: ffff:ffff matches
nothing on any machine and reaches the not-found arm, while 046d:c077
(control=on) and 046d:0825 (control=auto) are read-only probes, each guarded
so the case self-skips with a note if the host state changes rather than
silently asserting nothing.
Split across two test files to stay under the 250-line cap; run_all.sh globs
test_*.sh, so splitting costs nothing.

First of the 16 untested fixes/lib libs. Measured 37/37 = 100.00% through
lib/tests/run_all.sh, twice, the second run at --min 100 (exit 0), then
removed from the allowlist and confirmed with the real gate and no
exemption.
Adds two reusable pieces rather than a per-family harness clone:
- lib_test_core.sh -- PASS/FAIL tally, _t_eq/_t_contains/_t_lacks, a
mktemp -d sandbox wiped on EXIT, a FAKE_BIN stub dir on PATH, and
_t_stub/_t_unstub. _t_unstub runs `hash -r`: deleting a stub file alone
does not drop bash's cached executable path, so the real binary would
never be reached again.
- bt_harness.sh -- sources the core, sources the real scripts/lib/common.sh
for the production log_*/has_cmd helpers (verified inert at source time),
and redefines _btctl and apply_fix verbatim from fix_bluetooth.sh, since
those live in the entry script rather than in any lib. Same trade-off
pacman_hook_stall_harness.sh already makes with log_size.
pacman_hook_stall_harness.sh is deliberately left alone: its six libs are
already off the allowlist, i.e. gated at 100% with no exemption, so
refactoring it onto the new core would risk banked work for no gain. jscpd
reads 1.6% against the hook's own flags, and **/lib/tests/** is excluded
from that scan anyway, so the duplication budget is not at stake.
_t_only_path exists because every tool these libs call (usbreset, pactl,
lsusb, ...) genuinely exists on an Arch desktop: a prepended stub dir
cannot exercise a "not installed" branch, so those cases drop PATH to
FAKE_BIN alone.
The three coverage runs were made in a detached worktree: a second session
was writing to this repo concurrently, and the jail aborts on any
working-tree delta during a run.

The handoff recorded fixes/lib as having "no harness at all". It already had
8 test files and 2 harnesses. What was missing is run_all.sh -- the subject
is_covered() actually builds, and the only thing the gate measures through.
All 8 test files pass through it.
No jail_args beside it, deliberately: the harness confines every write to its
own `mktemp -d` and intercepts external commands with a PATH stub dir, and
grep finds no absolute write to /etc, /var or /usr in any of the tests. So it
runs bare, like the transcribe suite.
First measurement through it: pacman_hook_stall_usage.sh is 1/1 = 100.00%.
That denominator is honest, not broken -- the lib is a single usage() whose
body is one `cat <<EOF` heredoc plus `exit 0`, and heredoc content is data
rather than statements.
16 of the 22 libs there still have no tests at all. That is now the largest
block of real test-writing work left in the campaign.
Also rewrites NEXT_SESSION_PROMPT.md, whose central claim ("the instrument is
the bottleneck, not the tests") stopped being true this session. The new one
leads with re-measuring the 103 allowlisted libs on the fixed instrument
before writing any new test.

Two defects found in review, both of which made checks PASS more easily, so
neither ever went red.
GATE: is_covered() hardcoded its jail flags and never read the jail_args
marker that ci_mirror.sh and shell-tests.yml both consume. The features/lib
suite needs /usr/local/share and /etc/pki and aborts under set -e without
them -- but the coverage number still printed, because kcov had already
recorded whatever the dead run reached. The gate would have graded 44 libs on
a suite that never finished. It now reads the marker, keeps the historical
defaults for suites without one, fails closed on an empty marker, and passes
--fail-on-case-error.
Negative control: stripping the binds makes the gate exit 1 and restoring
them returns exit 0. Before this commit both cases exited 0 -- the gate could
not fail on an aborting suite.
HASH CACHE: the _t_unstub helper written earlier today for the transcribe
harness was needed in features_harness.sh too. Two assertions were vacuous --
test_dwm_config's "verify still reports when dwm is absent", and
test_rpi_nc_ca's uname removal, where a cached uname left every later branch
running under a faked Darwin. All four `rm -f "$TEST_TMPDIR/bin/` sites in
the repo were audited; the other two are sound (one probes with [[ -f ]], the
other runs in a subshell).
No measured figure moved: dot_resolver_install.sh still 39/39 = 100.00% with
real absence enforced, so its off-allowlist clearance holds.

A 38-assertion suite for the last lib in the directory without one. Every
one of its five libs now has a suite; at the start of the session it had
none. 118 assertions across the directory, 0 failures.
build_filters is asserted on the EXACT filter string it emits, because that
string is the lib's entire product. An arnndn chain missing its mandatory
48 kHz resample, or a preset silently falling through to no dynamics, yields
worse audio and never an error -- nothing else would catch it.
Every exit code is pinned: 1 for a missing command, 11 for "RNNoise required
but unavailable" (refusing to quietly fall back to afftdn), 8 for an ffmpeg
whose afftdn lacks md=.
Measured 83/93 = 89.25%; it stays on the allowlist. All ten uncovered lines
are the documented under-report, not gaps: an `exit 66` sentinel proves
require_cmd's lines 37-38 execute, 52-58 are a multi-line array literal (the
confirmed continuation-line artifact), and 129 is an empty `*) ;;` arm whose
branch has a passing assertion. The gate uses the measured figure, so the
exemption stands regardless.

A 29-assertion suite covering all six functions. transcribe_venv.sh measures
53/53 = 100.00% through the directory runner, and check_shell_coverage.sh
passes it with the exemption deleted.
Assertions are on recorded ARGV because which index a pip install points at
IS the behaviour: the OpenNMT cu12 wheel index on the NVIDIA path, the
CPU-only torch index for diarization (forced to avoid mismatched CUDA
builds). "pip was called" cannot see either.
generate_test_audio's four-deep fallback chain is covered by failing each
generator in turn. Every stub materialises the wav, because the chain
advances on `[[ ! -s $tmpwav ]]` -- a record-only stub would silently
exercise the branch after the one under test.
One assertion was wrong and got corrected rather than forced: I claimed a
wholly-failing pip still returns 0, but the final `python "$PY_HELPERS"
deps-installed` carries no `|| log`, so it does not. The suite now asserts
what the subject actually guarantees -- all four warnings emitted, no earlier
failure aborting the run.
SC2016 fixed at the source with a quoted heredoc, not suppressed.

The first allowlist removal of the campaign this session. unity_handler.sh
measures 32/32 = 100.00% through its directory's runner, and
check_shell_coverage.sh passes it with the exemption DELETED -- the real
gate, not just the measurement.
HARNESS BUG found getting there: bash caches executable locations in a hash
table, so `command -v foo` keeps succeeding after foo is removed from the
stub dir. Every "tool is missing" test was therefore running as a "tool is
present" test, asserting the opposite of its own name while looking
plausible. Reproduced minimally: after rm, STILL FOUND; after `hash -r`,
gone.
A _t_unstub helper now removes the stub and clears the table. The two suites
committed an hour ago had the same defect and are corrected here --
test_transcribe_pkgmgr.sh goes from 15 to 18 passing assertions, so three of
its checks had been vacuous. This is exactly the failure the campaign exists
to catch, found in its own test code.
`basename` joins the restricted PATH because the SUBJECT calls it; the suite
avoids needing `tail` via a parameter expansion instead, since every binary
in that PATH is one more thing a stub's shebang can trip over.
transcribe_deps.sh (92.31%) and transcribe_pkgmgr.sh (98.00%) re-measured
unchanged and stay on the allowlist.

The directory held five allowlisted libs and no tests. It now has a harness,
a runner, and suites for two libs: transcribe_deps.sh (the fourth
hardest-first target, 48/52 = 92.31%) and transcribe_pkgmgr.sh (49/50 =
98.00%). Both stay on the allowlist. 15 + 18 assertions, 0 failures.
No jail is needed here and no jail_args marker is created: every branch turns
on `command -v <manager>` and every install goes through sudo, both
intercepted by a PATH stub dir. Verified the runner exits 0 when invoked
bare, which is how both gates call it.
The harness REPLACES PATH rather than prepending. This host really has
pacman, and a prepended stub dir cannot HIDE a binary, so every "manager not
installed" case would have asserted nothing. `bash` and `env` are in the
private coreutils dir for a non-obvious reason: every stub's
`#!/usr/bin/env bash` shebang resolves through that restricted PATH, and
without them each stub died with "env: 'bash': No such file or directory"
while looking exactly like a coverage gap.
Assertions are on recorded ARGV rather than on the call happening, because
which packages a branch installs is what differs between distros --
pacman gets python-virtualenv where apt gets python3-venv.
Three assertions aimed at the libsndfile branch were REMOVED rather than left
green-but-vacuous: /usr/lib/libsndfile.so exists on this host, so
need_libsndfile is legitimately 0 and lines 19/52/53/55 are unreachable
without a jail that hides the library. The limitation is written into the
suite instead of asserted around.

A 26-assertion suite for rpi_nc_ca.sh, third in the hardest-first order. All
five OS branches are exercised by seeding the marker file each one tests for
inside the jailed /etc, plus a uname stub for Darwin; both NSS stores and all
three Firefox outcomes are covered.
SHARED-FILE BUG: the Debian branch does `mkdir -p
/usr/local/share/ca-certificates` and jail_args bound only /usr/local/bin, so
the suite aborted there under set -e. /usr/local/share and /etc/pki are now
bound. jail_args is shared by every suite in the directory, so all five libs
were re-measured: dot_resolver_install.sh still 39/39 = 100.00%, and
rpi_nc_install.sh, dwm_config.sh and aw_autostart.sh are unchanged. An
over-aggressive mount looks exactly like unreachable code, so this check is
not optional.
That bind also unblocked the runner for the whole directory: with the old
args the run exited 1 before nc_php.sh could be measured at all.
Measured 72/73 = 98.63% through run_all.sh, which is the exact subject
is_covered() builds -- the gate's own view -- so the lib STAYS on the
allowlist. The single test file alone reports 73/73 = 100.00%, both figures
reproduced twice. The one-line delta is line 141, the first line of
show_help's heredoc BODY: not a statement, so the denominator is wrong rather
than a test missing. Excluding heredoc bodies from the denominator is the
next piece of work; it is what stands between this suite and the bar.

Claude-Session: https://claude.ai/code/session_016sxxsDHWgdRhmdmzNMA6XM
A 25-assertion suite for aw_autostart.sh, second in the hardest-first order.
The generated i3blocks status script is asserted by RUNNING it against
stubbed pacman/pgrep across all four of its branches -- uninstalled,
installed-but-stopped, running, installed-via-package -- rather than by
grepping the heredoc's text. A heredoc that emits syntactically broken bash
passes a text check and fails in front of the user.
One assertion was silently testing nothing at first: aw-qt is genuinely
installed at /usr/bin/aw-qt on this host, so the "not installed" case found
the real binary through the PREPENDED stub dir. PATH is now REPLACED for that
one case. The suite went 24-passed-1-failed -> 25-passed-0-failed, and the
gate caught it rather than the number.
Measured 68/82 = 82.93%; it STAYS on the allowlist. The residue is the
`[[ $EUID -eq 0 ]]` false branches, which are unreachable inside the jail
because the process is uid 0 there, plus the documented kcov under-report --
an `exit 44` sentinel proves create_i3blocks_status runs to completion while
its lines 145-162 report zero hits. Third lib to show it.

A 27-assertion suite for dwm_config.sh, the highest-scored remaining
allowlisted lib. It drives the lib for real inside the jail: rewriting dwm.c
with perl, appending to config.h, compiling with cc and installing into
/usr/local/bin. The generated content is asserted, not just the call.
LATENT BUG, found by writing the test: apply_fullscreen_confine_hook does
`on=$(grep -c 'pconfine-auto on' "$src")`, and grep -c exits 1 when the count
is zero. The caller runs `set -euo pipefail`, so the function aborted at that
line exactly when the count was zero -- which is precisely when the
"setfullscreen/unmanage were likely refactored upstream" warning three lines
below was the thing needed. The warn branch was dead code in the only
situation it exists for. Both call sites now use `|| true`, and the suite
asserts the warning fires.
Measured: dwm_config.sh 35/73 = 47.95%. It STAYS on the allowlist -- the bar
is 100% and it is measured, not asserted.
That number is an under-report. An `exit 43` sentinel proves build_install,
build_pointer_confine, write_session_files and verify all execute inside the
jail while kcov reports their bodies at zero hits. One kcov artifact is now
CONFIRMED against a minimal repro: continuation lines inside a multi-line
quoted argument (the `perl -0777 -pe '...'` blocks) are counted as
statements that never run, which is the wrong denominator. A sixth
hypothesis -- that the exec-ing sudo shim or a pipeline loses the trace --
was tested and disproven. The two-strike time-box on this hunt is spent;
docs/shell-split-verification.md records what is known, including the
exit-sentinel technique for telling a tracing failure from an aborted suite.

ci_mirror.sh and shell-tests.yml discovered every */lib/tests/run_all.sh and
invoked it bare. The features/lib suite refuses to run bare -- that guard is
what stops it rewriting the real /etc -- so the pre-push gate blocked all six
pending commits, and CI would have gone red on the same suite the moment they
landed.
A suite now DECLARES its jail requirement with a jail_args file beside its
run_all.sh, holding the --bind/--seed-* flags it needs. Both consumers branch
on the marker. The 105 still-allowlisted libs were scored on root ops and
system writes, so most future suites will need the jail too; naming the path
in two runners would drift, which is the failure ci_mirror.sh's own comments
say it exists to prevent.
Both branches fail closed: a marker present but empty is an error, not a skip.
Verified the extracted flags reproduce the independently measured
dot_resolver_install.sh 39/39 = 100.00%, and that the other five suites still
pass bare.

rpi_nc_install.sh is one 200-line function that apt-installs 24
packages, seeds MariaDB, rm -rf's /var/www/nextcloud, rewrites Apache
and PHP config and installs a www-data crontab. 29 assertions, run for
real inside the jail. The destructive step is the point: a bug in
`rm -rf /var/www/nextcloud` is invisible to any check that does not
actually run it.
Two latent bugs in the ALREADY-COMMITTED nc_php suite, both found by
finally reading its assertion results instead of only its coverage
percentage. It was failing 2 of 29 in isolation:
- the cron entry arrives on crontab's STDIN, not in argv, so asserting
on the call log could never have passed for the right reason. The
stub now records stdin.
- configure_mariadb's stdout is eaten by `db_password=$(...)`, so the
phase-order marker now goes to stderr and the capture reads both.
Suites now: 28 + 30 + 29 = 87 assertions, 0 failures.
KNOWN AND UNEXPLAINED: kcov mis-measures rpi_nc_install.sh at 10/88 =
11.36%, recording lines 13-54 and nothing after -- yet the code past
line 54 provably runs, since /root/.nextcloud_db_password and
/etc/apache2/sites-available/nextcloud.conf both exist afterwards. The
three obvious culprits were each tested against a minimal reproduction
and DISPROVEN: kcov traces fine past a heredoc, into a $( ) command
substitution, and past a heredoc-fed stub reading stdin via $(cat).
The file stays on the allowlist and the suite is kept for its
assertions, not its percentage. Do not 'fix' the number by weakening a
test.

nc_php.sh was the next-hardest library on the allowlist. It targets a
Debian Raspberry Pi -- it edits /etc/php/<ver>/apache2/php.ini, drives
occ as www-data and installs a crontab -- so none of its write targets
exist on this Arch host and the jail had nothing to mirror.
- --seed-dir / --seed-file create the paths a foreign-platform subject
expects. Verified with a probe: /etc/php/8.2/apache2 exists inside
the jail while /etc/php does not exist outside it.
- A failed bind is now FATAL, and missing mountpoints are created
first. A bind that fails silently is indistinguishable from
unreachable code in the report, which is the misdiagnosis this
runner exists to prevent.
- Mirroring skips unreadable targets (/root as a normal user) rather
than aborting under set -e.
nc_php.sh: 84/85 = 98.82%, 24 assertions. It STAYS on the allowlist,
because 98.82% is below the bar. Line 111 -- the crontab first-run
fallback -- hung the suite on both attempts to cover it, so it is left
uncovered and documented rather than tried a third time.
Two harness hazards found the hard way and written down: a top-level
stub function shadows the subject's own function for every later
assertion (this silently dropped coverage 83.53% -> 57.65% while the
tests still passed), and a stub for a piped-into command must drain
stdin or the writer takes SIGPIPE.
dot_resolver_install.sh still measures 39/39 = 100.00%.

The gate was a presence check -- 'a run_all.sh exists beside this lib' --
which an empty suite that asserts nothing satisfies. It now measures.
100% is reachable with no suppressions and no production source changes:
run the suite inside a user+mount namespace and the sudo-writes, systemd
units and nftables rules execute for real against a throwaway /etc.
- meta/scripts/shell_coverage_jail.sh: the runner, promoted out of a
session scratchpad. Two fixes it needed on the way: bind targets mirror
the real directory tree (an empty bind makes writes fail with ENOENT,
which reads as unreachable code), and sudo gets a pass-through stub
because real sudo cannot setresuid inside a userns.
- It fingerprints git status before and after and fails the run if a
write escapes the jail. Verified with a deliberate escapee.
- dot_resolver_install.sh: 39/39 = 100.00%, 28 assertions. Picked by
scoring every allowlisted lib on root ops, system writes and
destructive calls -- it scored highest in the repo. Allowlist 106 -> 105.
- jscpd was already over its own threshold at 2.45% and would have
rejected every commit staging a .sh file. Excluding vendored .venv/
shell alone gives 1.67%; also excluding lib/tests/ gives 1.47%.
The gate is deliberately NOT wired into the hook chain yet.

Gives linux_configuration/scripts/lib a real test suite, which takes all
nine of its libraries off meta/shell-coverage-allowlist.txt at once —
coverage is per-directory, so this is the highest-ratio first batch.
139 assertions across four suites, all offline: the mtk toolkit is driven
through its existing MTK_ROOT_FIXTURE seam, and adb is shimmed onto a
narrowed PATH. Nothing reads the wall clock, this host's udev rules, or a
real device, because the suite runs in shell-tests.yml and again on every
pre-push via ci-mirror — a host-dependent assertion would be a flake that
blocks unrelated pushes.
The gate only checks that tests/run_all.sh EXISTS, so an empty one would
mark all nine libraries covered while testing nothing. Each of the four
load-bearing rules was therefore mutation-tested and the suite required to
go red: classify_device's && -> ||, discover_partitions' init_boot/boot
ordering, mtk_select_device's refusal to guess between two phones, and
is_hour_in_range's 10#$ octal guard.
That last one initially SURVIVED. Dropping 10#$ makes bash abort with
"value too great for base", a non-zero exit indistinguishable from an
honest out-of-range result, so the status-only assertion passed either
way. It now asserts stderr is empty.

The template checks were grepping an empty argument list. SETUP_SOURCES was
initialised as SETUP_SOURCES=("${SETUP_SOURCES[@]}") — a self-reference to an
array that did not exist yet — so it started empty, never contained
$SETUP_SCRIPT, and the lib-discovery loop ran dirname on nothing.
CI reported "setup_midnight_shutdown.sh should install the D-Bus monitor
helper". Reproduced locally before changing anything, so the fix is verified
against the real failure.
Seeding it with ("$SETUP_SCRIPT") restores the intent: search the entry
script together with lib/ms_*.sh, since the monitor template moved into
lib/ms_monitor.sh during the split.
test_pacman_wrapper_security.sh and test_hosts_guard_pacman_integration.sh
re-checked at the same time and both pass, so the Shell tests set is green
again before the file-length gate goes in.

1734 -> 109 lines across eight libs plus one payload file. This was the last
file over the 250-line cap; check_file_length.sh --all now reports "all
checked files are within 250 lines".
This file needed a different proof from the others. Its product is scripts
generated into /usr/local/bin via heredocs, so "did the functions move
verbatim" is not the question that matters — "does it still emit the same
bytes" is. Every heredoc body was hashed before the split: 11 of 12 are
byte-identical afterwards, and the twelfth (the 224-line config-unlock body)
now lives in lib/payloads/shutdown-config-unlock.sh.in at hash
1a5c67cfd0244101, exactly matching what it replaced. No new bodies appeared.
The "~39 top-level functions" this file is documented as having are not real.
log(), now_epoch(), cmd_add() and friends sit at column 0 because they are
inside the generated scripts. The brace-matching extractor keeps each heredoc
with its owning generator, so they moved as part of it. That is also why
verify_shell_split.sh reports a bare "-log": it cannot tell a heredoc-internal
definition from a top-level one. log() is not lost — it is line 17 of the
payload, which is where it always ran from.
$_MS_PAYLOAD_DIR is defined in the same file as its use, directly above it,
following the _NL_PAYLOAD_DIR lesson from earlier in this campaign.
--help is byte-identical, shellcheck is clean with no suppression added.
`setup` itself is not executed — it installs systemd units, makes the config
immutable and arms a shutdown timer.

Shell tests has been red since fbe9134c. Three assertions across two
files grep pacman_wrapper.sh for functions the split moved into the flat
pw_*.sh libs: pacman_hooks_manage_guard_lib and
should_use_wrapper_guard_lib_fallback (pw_guard.sh),
verify_policy_integrity and the two -U helpers (pw_policy.sh), and
auto_remove_virtualbox_vms plus VBoxManage (pw_cleanup.sh).
Each grep now searches the entry script and its libs together, via a
pw_*.sh glob rather than a named lib, so a future re-partition does not
break them again. The sed extraction in the security test reads
pw_policy.sh directly, since it runs those two functions in isolation.
Deliberately left narrow: the two assert_order checks still target the
entry script alone. They assert the order of two call sites, and both
calls are still there -- widening them would turn a positional check
into a meaningless one. The 'CRITICAL near verify_policy_integrity' and
auto_remove_virtualbox_vms call-site greps were also left alone after
confirming they still match in the entry script.
Both files now exit 0. Of the two other suites still failing locally,
neither is from this commit: test_security_hardening's remaining failure
is this machine's unwrapped signal-desktop/discord and passes in CI, and
test_shutdown_timer_monitor is failing on the uncommitted
setup_midnight_shutdown split in the working tree.

929 -> 217 lines across five pw_*.sh libraries. This file IS /usr/bin/pacman
here (the symlink points at the deployed copy), so the design constraint was
not readability but that no failure mode may leave the machine unable to
install packages.
Fail OPEN, unlike the other splits in this campaign. A missing lib warns on
stderr and execs real pacman unwrapped. Failing closed would mean a missing
lib leaves no way to install anything, including the missing lib. This is the
same choice the existing pacman_lock_lib.sh block already makes, and it is
verified rather than asserted: with pw_guard.sh removed from a scratch-dir
copy, the wrapper warns, execs, and returns real `-Qi bash` output at rc=0.
The libs load at the very top, before the fast path, because the fast path
calls needs_unlock() to decide whether to exec straight through, and that
function now lives in pw_guard.sh.
They are deployed flat beside the wrapper — the shape pacman_lock_lib.sh and
heavy_job_lock.sh already use in /usr/local/bin — as required copies, and are
added to the integrity manifest. Tamper detection was round-tripped in a fake
root: 8 manifest entries verify clean, and appending one line to
pw_challenge.sh is detected and the transaction denied.
Verified by execution, not just textually: real `-Qi bash` and `-Q` through
the split wrapper are byte-identical to the pre-split baseline, same 2824
packages. verify_shell_split.sh reports all 14 top-level functions moved
verbatim.
The deployed copy is deliberately NOT updated by this commit and still hashes
548fc2b5... exactly as before the work started; live pacman is unaffected.
A live `pacman -S` remains unverified — the Bash tool deadlocks on db.lck and
a failed experiment costs the package manager.
Cap is now down to one file.

The block_compulsive_opening split moved launch_with_timer into
lib/cco_wrapper.sh, and tests 17 and 18 grep the entry script alone. CI went
red on "launch_with_timer function exists — Not found at expected location":
a false failure about code that is present and working, one file over.
Both assertions are about a feature existing, so they now search the entry
script together with lib/cco_*.sh. That restores what they were always
checking and does not go stale on the next split.
The lib list is built with a loop and an -f test rather than a bare glob, so
an unmatched pattern cannot land in the array as a literal and no shellcheck
suppression is needed.
Verified by running the suite: both checks PASS, 18 passed. The one remaining
local failure is test 19, which inspects /usr/bin on this machine — signal
and discord are not currently wrapped here and beeper is not installed. That
is machine state, predates this change, and is not what CI reported.

The split referenced $_NL_PAYLOAD_DIR from both install functions but
defined it nowhere, so `setup_night_lockdown.sh setup` would have died
with an unbound variable partway through installing the lockdown. My
earlier scratch verification set the variable by hand, which is exactly
what hid the bug: the emitted artifacts hashed correctly while the real
entry path could not have reached them.
It is now defined in each lib that uses it, eight lines above the use,
via `: "${_NL_PAYLOAD_DIR:=...}"` so an explicit override still wins. A
definition placed in the entry script was silently stripped by an
autoformat pass three times during this work, and a half-run lockdown
installer is not an acceptable failure mode.
Also drops two zero-byte payload files left behind by the .sh -> .sh.in
rename.
Re-verified without presetting anything: install_enter_script and
install_unlock_script emit mode-0755 files hashing 4baaf405... and
eafce28d..., byte-identical to the live /usr/local/bin copies. help and
an unknown command match their baselines; status differs only by the
05:00 countdown ticking 13h to 12h between runs.

918 -> 138 lines, across five libs plus two data-file payloads.
The two generated scripts became data files rather than heredocs.
ENTER_EOF alone was 279 lines, so any lib containing it would have been
over the cap however the rest was arranged. Both heredocs were quoted,
so their bodies were already literal text with no build-time
interpolation, and copying them verbatim is exactly equivalent.
The payloads are named *.sh.in on purpose. The pre-commit hook globs
staged files by '\.(sh|bash|zsh)$', runs shfmt -w on them and re-stages
the result -- and shfmt does reformat these bodies. That would have
changed their bytes and destroyed the property this split is verified
by. The .in extension keeps them out of every .sh-globbing hook without
a suppression or an exclude regex.
cat + chmod 0755 became a single `install -m 0755`, closing the window
the original left between creating the file and making it executable.
The load-bearing check: running install_enter_script and
install_unlock_script against a scratch directory produces mode-0755
files whose sha256 sums are identical to the copies already deployed in
/usr/local/bin on this machine. The split provably emits the exact bytes
that are running today, and it touched no system file -- sha256sum -c on
both deployed artifacts passes unchanged.
help, status and an unknown command are byte-identical to their
pre-split baselines. A line-multiset check leaves exactly six lines
unaccounted for: the two cat/heredoc openers, the two terminators and
the two chmod calls that install -m now performs.

21 assertions for cco_state.sh, the lib that decides whether a launch is
permitted. Coverage measured: 62/66 lines = 93.94%. The only uncovered lines
are kill_app's pkill/pkill -9 pair, which must never run in a test on a
machine whose apps are live. cco_wrapper/cco_install/cco_report stay at 0%:
every function in them moves system binaries, writes /etc/pacman.d/hooks or
kills processes.
The assertion that matters most is the one in the negative direction: a
PREVIOUS hour's stamp must NOT keep blocking. If that decision inverted, a
legitimately-closed app could never be reopened, and the failure would look
like the tool working. Both directions are pinned, plus the empty-stamp case
and stale suspend-marker cleanup.
Also generalises run_all.sh from test_leechblock_*.sh to test_*.sh. This
directory now holds suites for more than one entry script, and a prefix glob
silently skips every suite added after it — including inside the CI discovery
step added in fbec4656, which runs this file.
The harness asserts its own fixture is complete rather than letting a typo in
a global surface as a confusing unbound-variable from inside the code under
test. That check is also what makes the fixture's globals legible to
shellcheck, which cannot see them being read across the source boundary — a
real check that happens to remove SC2034, not a suppression.

705 -> 182 lines, with state, the launch gate, install/uninstall and
reporting moved into cco_state.sh, cco_wrapper.sh, cco_install.sh and
cco_report.sh.
The entry script keeps its exact deployed path and stays a real file
there, not a symlink: the app wrappers already installed on disk
hard-code /usr/local/bin/block-compulsive-opening.sh, and the pacman
hook invokes it. _CCO_LIB_DIR probes for lib/ beside the script and
falls back to the script's own directory, so the repo tree and the flat
/usr/local/bin deploy layout both work; both branches were exercised.
install_all deploys the libs and uninstall_all removes them in this same
commit, so there is never a deployed copy that is split but missing its
libs -- the failure that had to be repaired for install_leechblock.
The libs deploy flat into /usr/local/bin rather than into
/usr/local/share/digital_wellbeing/lib, because install_leechblock_payload
does an rm -rf mirror of that directory and would delete them.
Verified beyond the usual gates: a line-multiset check reports zero
missing functional lines, and all three heredoc bodies -- the generated
app wrapper, the generated pacman hook and the help text -- are
byte-identical, which verify_shell_split.sh cannot check. status output
matches the still-monolithic deployed copy byte for byte.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The pacman-wrapper installer copied install_leechblock.sh to
/usr/local/share/digital_wellbeing/ along with three data files, but no
lib/. After the split in 1dceca66 the deployed entry script sources
every install phase from lib/ beside itself, so deploying it without
that directory leaves a copy that dies on its first `source`.
This is not hypothetical: the live deployed copy was found in exactly
that state at the start of this work -- the previous session's split
entry script, deployed and then left behind when the repo was reverted.
It failed on every invocation. It has been repaired and now carries the
libs.
The glob is leechblock_*.sh rather than *.sh because lib/ is shared with
unrelated music_* helpers that have no business in /usr/local. The copy
mirrors rather than merges, so a lib deleted upstream does not linger.
Verified against a fake root and then for real: the deployed copy runs,
its sha256 matches the repo, and inject_default_config resolves the
defaults JSON and the seeder from the deploy root rather than from lib/.

29 assertions across two files, run via lib/tests/run_all.sh.
Coverage measured, not waived: leechblock_fetch.sh 38.57% (27/70),
leechblock_browsers.sh 36.47% (31/85), config and firefox 0%. The uncovered
lines are exactly the bodies that must never run under test — curl/tar/unzip
downloads, pkill + sudo binary patching, npm install, and writes to
/etc/*/policies.json. Closing the gap needs those externals shimmed.
What the tests actually pin down:
- all three get_latest_tag fallbacks (releases API, tags API, Location
header), plus JSON-null-is-not-a-tag and the all-sources-exhausted
non-zero return. A silent failure there installs the wrong version.
- the 8+3 browser tables including every hyphenated key, and the
command -v gating that decides whether a binary is patched at all.
Also fixes a latent set -u abort: wire_up_browsers interpolates VERSION_DIR,
VERSION and TAG, which only resolve_version sets. Calling it on its own
aborted on an unbound VERSION_DIR; they are now read through locals with
defaults, leaving production output unchanged.
Harness note: PATH must be narrowed to the shim dir for "no browser
installed" to be testable on a machine that has five, but every external the
code under test calls has to be seeded there too — a missing mkdir aborted
the suite under set -e with no stderr, which under kcov looked like a
coverage-tool bug rather than a PATH bug.
The hyphenated array subscripts in the test are quoted for the same reason
they are in the lib: shfmt -w rewrites an unquoted [google-chrome-stable]
into a subtraction expression. Reproduced live in this file during the work.

485 -> 114 lines, with the six install phases moved into four sourced
libs: leechblock_fetch.sh, leechblock_config.sh, leechblock_browsers.sh
and leechblock_firefox.sh.
detect_browsers, replace_browser_in_place and wire_up_browsers stay in
one lib on purpose: detect_browsers writes the BROWSERS/FIREFOXES arrays
that wire_up_browsers reads, and splitting them would create a
write-only cross-file global.
Four justified body changes, all recorded in the evidence:
- Quoted the six hyphenated associative-array keys. shfmt 3.13.1 parses
an unquoted [google-chrome-stable] as arithmetic and rewrites it to
[google - chrome - stable], which would break browser detection
entirely. The pre-commit hook runs shfmt -w on staged files and
re-stages them, so this corruption would have landed in the commit
unseen -- this is what caused the previous attempt at this split to be
reverted. Behaviour-preserving: quoted and unquoted are the same key.
- SCRIPT_DIR is assigned in the entry script rather than inside
inject_default_config. Left in the lib, ${BASH_SOURCE[0]} resolves to
lib/, so the defaults JSON lookup would miss and default blocking
rules would silently never be seeded.
- install_firefox_policy takes ff_found as a parameter instead of
reading it as a cross-file global, fixing a genuine SC2154 without a
suppression.
- Added require_cmd unzip. It was used bare under set -Eeuo pipefail, so
a missing unzip would abort after the version dir was populated but
before the 'current' symlink was made, leaving a half-installed tree.
verify_shell_split.sh reports additions only -- no -/+ pair -- so
get_latest_tag and replace_browser_in_place moved byte-identically.
--help and unrecognized-flag output are byte-identical to the baseline.

913 lines down to 150. The ten functions were only 202 lines; the other 712
were a single top-level block, now eight phase functions across six libs. As
in the previous split the bodies were wrapped WITHOUT re-indenting, because
five heredocs use quoted terminators that must stay at column 0 (shfmt
indented them afterwards, which is safe).
The ~320-line custom-blocklist heredoc became custom_entries.hosts. It was
321 of the 370 lines of hosts_write.sh and cannot be split, so that lib could
not otherwise fit the cap; a hosts-format data file is also far easier to
audit and diff than a quoted heredoc.
That move broke a guard, which is the important part of this commit:
extract_custom_entries_from_script sliced the blocklist out of the script
between "# Custom blocking entries" and the heredoc terminator. With the
entries in a data file there is no terminator, so it would have extracted
NOTHING -- and check_custom_entries_protection, the guard whose entire job
is refusing to drop blocked domains, would have compared against an empty
list and passed everything. It now reads the data file, and the extracted
set is identical: 254 domains, diffed.
A second, pre-existing bug surfaced while testing:
extract_unblock_entries_from_script matched its OWN marker lines.
PROTECTED_UNBLOCK_LIST_START and _END are word characters, so the
'^# [a-zA-Z0-9._-]+$' pattern pulled both into the whitelist as if they
were domains. Both are in this machine's live state file right now.
Renaming either marker would have read as the whitelist growing and blocked
the install outright.
There is no dry-run or status mode, so this file cannot be proven by running
it: an aborted run leaves /etc/hosts mutable with the guard's bind mount down.
The proof is textual instead. Every one of the 8 wrapped phase bodies is
byte-identical to its original line range; a line-multiset check found 0 lines
lost; and an indentation-insensitive comparison against the pre-split file
leaves exactly 8 absent lines, each an intentional edit (the rewritten
extractor, three `readlink -f "$0"` made overridable, the /etc/hosts fallback
made overridable, and the heredoc markers). /etc/hosts is byte-unchanged
across the whole session, and `--help` output is identical.
36 assertions. Both anti-tamper guards at 100% line coverage (75/75 and
49/49), covering both directions of each: removing a blocked domain is
refused and adding one allowed; growing the whitelist is refused and shrinking
it allowed. A same-count swap is refused too, which a count-only check would
have let through.
The install phases themselves are deliberately untested -- running them would
take down the protection they install. That is weaker evidence than the two
previous splits had, and it is inherent to this file rather than a gap.

1017 lines down to 148. Six libs: the per-language doc-URL builders (split in
two only for the cap), the lookup/dispatch layer, and one per generation phase.
The hard part was not the ten functions but the 335-line top-level block,
which extract_shell_functions.py cannot move because it only relocates
functions. It is now generate_doc_links / generate_anki_cards /
generate_llm_prompt, wrapped WITHOUT re-indenting the bodies: five heredocs
use quoted terminators, which must stay at column 0.
Proof the split is behaviour-preserving: a golden fixture captured before any
edit, re-checked after every step. All three outputs -- anki_cards.txt,
documentation_links.md, llm_anki_prompt.md -- stay byte-identical by sha256sum,
and stdout matches too.
Four latent defects surfaced while writing the tests, all fixed:
python_doc_url required a $2 it never reads, and get_doc_url has always
called it with one argument. That only worked because the entry script runs
`set -e` without `-u`, so "$2" silently expanded to empty; any caller with
`set -u` aborted. Defaulted, along with three more positionals documented as
optional but declared required.
The two imports loops hardcoded `head -20` while the other seven honoured
TOP_N, so --top was silently ignored for imports.
Only one of nine term loops skipped comment lines, so a '#' line in an
analysis file became a flashcard whose front was a comment.
Introduced and fixed within this change: the comment filter has to run
BEFORE `head -n` or comment lines count against the limit, and it needs
`|| true`, since grep exits 1 when it filters every line and the callers run
under `set -e`.
The golden fixture cannot show the last three, because it has no comments and
fewer than 20 imports -- which is exactly why they survived. A second fixture
with 25 imports and comment lines, at --top 3, emitted 20 imports and two
comment cards before, and 3 imports with zero leakage after.

Eight checks assigned status="warning" unconditionally, so a check running
later in the same function overwrote the status="error" an earlier one had
set. The five other sites in this family already guard the assignment with
`if [[ $status != "error" ]]`, so this was an inconsistency, not a design.
Only half of it was load-bearing, and the two halves fail differently:
services_units.sh (4 sites) reports through report_and_fix, which repairs
ONLY on "error". A downgrade there meant no repair ran at all. The is-active
check is the LAST status assignment in each of the three functions, so it
could mask any error above it -- in check_periodic_systems, three separate
is-enabled checks. A timer that was both disabled and inactive, which is the
ordinary shape of a broken timer, was reported and then left broken.
services_hosts.sh (4 sites) gates its own repair on `status != "ok"`, so the
repair still ran. There the bug printed a real error as a yellow [!] warning
and understated the summary row.
Demonstrated rather than argued, against a simulated broken machine (timer
disabled AND inactive, unit files present):
without the guards: status=warning, repair ran 0 times
with the guards: status=error, repair ran 1 time
The seven assertions that previously pinned the broken behaviour now assert
the correct behaviour; they were rewritten first and failed, then the guards
made them pass. Two further cases cover the masking shape directly: a broken
guard-lib instance must still be repaired when a later check warns.
`--status --dry-run` output is still byte-identical to rev 6691cb26, because
this machine has no disabled timer and no missing pacman hook -- the buggy
path is never taken here, which is precisely why it went unnoticed. The A/B
above is the evidence the live diff cannot provide.
222 assertions across 10 files. services_units.sh holds 100% coverage;
services_hosts.sh rises from 86.05% to 93.02%. test_services_hosts.sh needed
splitting twice to stay under the 250-line cap (hosts_fix, resolved), and
stage_hosts_ok moved into the harness so both new files can use it.

Follow-up to 9085a4e5, which recorded services_units.sh at 84.51% because
its remaining branches sit behind [[ -f /etc/systemd/system/*.service ]] --
absolute root-owned paths that exist on this machine, so the else-branch
never runs and no PATH shim can redirect it.
All 87 such paths across the seven check libs now go through $SYSROOT, read
from SERVICES_ROOT. The prefix is deliberately NOT defaulted. Three commands
in hosts_fix_resolved run outside `run` and so are not stopped by --dry-run
(chattr -i on resolved.conf.d, find -delete over its *.conf, and an append to
resolved.conf); with an empty default, a test that forgot to set SERVICES_ROOT
would really delete this machine's resolved.conf drop-ins. Unset is therefore
a hard error and only an explicitly empty value means the real filesystem.
The harness now owns PATH outright: $FAKE_BIN for shims and staged fake apps,
$REAL_BIN for a curated set of symlinks to genuine coreutils. The machine's
/usr/bin is deliberately absent -- a really-installed discord and chromium
otherwise make the "no target apps present" branches untestable, which is
exactly what happened until these tests caught it.
Coverage, measured against run_all.sh because two test files jointly cover
services_common.sh after the 250-cap split: common 55/55, report 27/27,
units 72/72 (was 84.51%), wrappers 100/100, apps 66/66, browser 79/79 --
seven libs at 100%. services_hosts.sh reads 86.05% and services_hosts_fix.sh
97.30%, and those 14 lines are a kcov attribution artifact rather than a gap.
Falsified rather than assumed: the suite prints "51 passed, 0 failed" when run
under kcov, so no group is skipped, and every supposedly-uncovered line is an
issues+=("...") whose string can only reach stdout through the print loop
below it -- with a passing assertion matching that exact string.
Two falsification checks, both re-run after the rewrite: `--status --dry-run`
as root stays byte-identical to rev 6691cb26 modulo the Date: line, and the
sha256sums of /etc/hosts, /etc/nsswitch.conf and /etc/systemd/resolved.conf
plus the contents of resolved.conf.d are unchanged across a full suite run.
The second one is what makes a missed prefix site detectable instead of a
matter of inspection: the repair paths really do write.
220 assertions across 8 test files. Also fixes a bug in the harness's own
lsattr shim, where printf with a leading-dash format string parsed the dashes
as options and silently produced nothing.

1225 lines down to 202, with the 21 functions moved into eight sourced
libraries grouped by subject. The entry script now holds only the
configuration, the argument parsing and the order the checks run in.
check_hosts was the one function that could not move verbatim: at 260 lines
it would have stayed over the cap on its own, so its repair half is now
hosts_fix_nsswitch / hosts_fix_resolved / hosts_repair_all in
services_hosts_fix.sh. Repair order is preserved (resolver config, then the
hosts file, then the guard-lib migration), and hosts_repair_all returns
non-zero under --dry-run so a dry run can no longer promote a status to "ok"
on the strength of repairs that never happened.
SERVICE_STATUS was a write-only global across five libs, which is a real
SC2034 rather than noise: the pre-commit hook runs shellcheck with no -x and
genuinely cannot see the one reader. It now goes through set_service_status /
get_service_status, which also rejects a duplicate write — each check owns
exactly one summary row, so a second write means two checks are fighting over
it. No suppression was added anywhere.
Proof the behaviour is unchanged: `--status --dry-run` run as root against
this machine is byte-identical to the same command from a worktree at the
pre-split revision, modulo the Date: line. verify_shell_split.sh reports
check_hosts as the single expected difference; the other 20 functions hash
identically. 72 assertions across three test files pass, with 100% line
coverage on services_common.sh (54/54) and services_report.sh (27/27).
services_units.sh measures 84.51% (60/71). The 11 uncovered lines are the
else-branches of [[ -f /etc/systemd/system/*.service ]] and
[[ -f /usr/local/bin/*.sh ]] probes — absolute root-owned paths that exist on
this machine and that no PATH shim can redirect. Reaching them needs a
root-prefix rewrite of live enforcement logic, which is not a line-count fix
and would forfeit the verbatim-move proof for everything else.
Found while testing, deliberately NOT fixed here: in all three unit checks
the is-active branch assigns status="warning" unconditionally, overwriting
the status="error" the is-enabled branch set just above it. A timer that is
both disabled and inactive therefore never gets repaired, because
report_and_fix only repairs on "error". It is identical in the pre-split
file, so this split neither caused nor hides it. The tests pin the current
behaviour and name it; fixing it changes enforcement and earns its own commit.

Regression from this session's earlier commit (327d48b): the test still
referenced pacman-hooks/*.sh and install_pacman_hooks.sh, which that commit
archived to testsAndMisc-archive. shell-tests.yml runs this test directly
(not scoped by pre-commit's --files), so it went red on CI without being
caught locally before the push.
Dropped the assertions tied to the archived files; kept and extended the
ones checking pacman_wrapper.sh's guard-lib fallback logic, which was
already fully guard-lib-native and unaffected by the archive.

setup_hosts_guard.sh was NEXT_SESSION_PROMPT.md's next split target, but
live-machine inspection showed it (and 16 supporting files - enforce-*.sh,
6 systemd units, install_pacman_hooks.sh, pacman-hooks/, psychological/,
both READMEs) is fully retired in favor of guard-lib, migrated 2026-07-04.
User confirmed archive over split, then confirmed the larger 17-file scope
once the directory was surveyed. Full history preserved via git filter-repo,
live at github.com/kuhyx/testsAndMisc-archive/tree/main/linux_configuration/scripts/periodic_background/hosts/guard.
plugins/{nsswitch,resolved}-plugin.sh stay - they're guard-lib's live
plugins, referenced by absolute path from /etc/guard-lib/targets/*.conf.
check_and_enable_services.sh's check_hosts() rewritten to check guard-lib
state (guardctl file-guard status) instead of the retired units/scripts it
used to check and self-repair - verified live, now reports the hosts
service ok against the actual migrated machine instead of a false error.
copilot-instructions.md and one install.sh comment updated to match.

Confirmed live (not dead code) via the dead-code check-in before any code
was touched -- the last two candidates this pattern was tried on were both
archived instead. Kept run_one/cleanup/log_size/main together in the entry
script: a prior session (2527fb3) already proved splitting run_one out
produces a real SC2153/SC2034 pair since PACMAN_PID/LAST_ELAPSED cross the
EXIT trap, not a suppressible false positive.
Fixed a real bug found while writing tests: print_summary's inline awk had
a dead `NR == 0` guard (printf on an empty array still emits one blank
line), reachable via `-n 0`. Refactored mem_available_mb, descendant_pids/
kill_tree, capture_stall's two output blocks, and print_summary's median
calc after confirming empirically (bash -x tracing) that kcov's
xtrace-based coverage can never see a `done <redirect>`, `} >redirect`, or
inline-awk line -- user chose to fix the code over the coverage tool.
descendant_pids specifically needed an explicit-fd process substitution
(not a pipe) to keep its array mutation in the current shell.
Made PACMAN_BIN/PACMAN_LOG/CACHE_DIR/PACMAN_LOCK/LOAD_FLOOR_MB/
LOAD_MIN_FREE_MB env-overridable for testing. Caught and fixed, before it
ran unbounded, a --with-load test that would have dd'd 13-20+ GB into
/dev/shm using this box's real available memory.
56 lib-level + 13 entry-level PATH-shim/subprocess assertions, 0 failed.
The entry test itself grew past 250 lines while adding coverage and had to
be split into a shared harness plus two test files, mid-session.

Wraps the four install stages into named functions, one per lib/plagiarism_*.sh
sibling (matching install_exercism.sh's convention), and extracts the two
embedded Python heredocs into real, lint-clean check_plagiarism.py/sherlock.py
files -- check_plagiarism.py needed a second split into plagiarism_similarity.py
to also clear the 250-line cap. Every function reaches 100% shell coverage via
a PATH-shim test harness (fake python3/pip/git/java/wine); the two Python CLIs
were separately verified against a real venv with actual nltk/scikit-learn.

Grouped by the state each function touches rather than by size:
steam_requirements.sh 199 requirement parsing, scoring, and the hardware
detection that feeds it
steam_report.sh 156 the run loop and the cache it reads
steam_api.sh 124 library discovery, Steam and ProtonDB calls
steam_credentials.sh 103 credentials, usage text, presentation helpers
The grouping was forced by the SC2034 writer/reader rule, not chosen. Two
arrangements were discarded: detect_system alone in a lib writes the three
SYSTEM_* globals without reading them, and load_cache_map alone writes
CACHE_MAP without reading it. Both were fixed by putting the writer next to
its reader - detect_system beside score_game, load_cache_map beside main.
Verified: all 33 functions verbatim; every lib passes shellcheck standalone
with no suppression; and the script actually runs - `--help` prints the usage
block and exits 0, which is what proves the four source lines resolve and
main still dispatches.
Over-cap files 26 -> 25.

clean_audio.sh 419 -> 230 + 204
enforce_vbox_hosts.sh 443 -> 220 + 236
migrate_hosts_guard.sh 444 -> 167 + 162 + 141
migrate_hosts_guard needed two libraries: with all ten work functions moved
the single lib was 295 lines, so migrate and rollback were separated.
The extractor's brace matcher required index > start and so silently skipped
one-line `warn() { ...; }` definitions. Fixed, and regression-checked against
the committed fresh-install/main.sh split byte-for-byte.
The harness earned its keep on a fourth file: adding `export` to libre_translate
to satisfy SC2034 changed two function bodies, and verify_shell_split.sh caught
what lint had accepted. Those exports were reverted, and libre_translate.sh is
parked - what remains after its clean seams both assigns and reads the same
globals, so getting it under the cap needs parse_args restructured rather than
relocated, which is a refactor rather than a verbatim move.
That cost is now written down: a lib must contain the readers of every global
it assigns. The precedent at install_pacman_wrapper.sh:29 is about
definitions-only libs, not about assignments as such, and the pre-commit hook
runs shellcheck with no -x, so a source= directive will not make it follow the
link. This is the shell analogue of the monkeypatch-target trap.
Verified: all 8, 13 and 19 functions verbatim; all four libraries source with
no side effects; shellcheck passes standalone on every file with no
suppression; bash -n passes on all seven. None of the three was executed -
they drive ffmpeg over real media, mutate VirtualBox guest disks, and rewrite
systemd units.

Two single-use scripts with no deployed copy, so the entry+lib shape is
safe. Each keeps the ordering, the safety checks and the user-facing output;
the configuration writers move to a library beside it.
Both scripts write `set -e # Exit on any error`, so extract_shell_functions.py
now matches the directive rather than the whole line. Regression-checked by
re-deriving the committed fresh-install/main.sh split byte-for-byte.
Verified: all 6 and all 9 top-level functions verbatim via the shfmt
harness; both libraries source with no side effects and define every
function moved into them; bash -n passes on all four.
Neither script was run. nvidia_troubleshoot.sh writes /etc/X11 config and
installs pyroveil; setup_passwordless_system.sh writes sudoers and lightdm
autologin, which is what this machine's login depends on.

The five package-installation functions move to lib/packages.sh; main.sh
keeps the top-level flow and sources the library after `set -e`.
The first attempt sliced by line range and was thrown away. This file
interleaves top-level commands - sudo -v, git config, the cp of
makepkg.conf and pacman.conf - between its function definitions, so a range
slice swept them into the library, where they would have run at source time
and in the wrong order. Sourcing that version blocked on a sudo password
prompt, which is how it was caught. The rebuild extracts function blocks by
brace counting and leaves every other line exactly where it was.
Verified with the new shfmt harness (all 5 functions verbatim), by a
structural comparison of the top-level flow showing exactly one line added
and none missing, and by sourcing the library to confirm it defines all five
functions with no side effects. The script itself was NOT run: it does
`sudo pacman -Sy`, overwrites /etc/makepkg.conf and /etc/pacman.conf, and
installs AUR packages.

The last Python file over the cap:
_transcribe_media.py 143 _try_import, both duration probes,
get_media_duration, ffmpeg transcode, cleanup
_transcribe_cluster.py 105 _resample_linear, _kmeans_cosine and its
iteration loop
_transcribe_diarize.py 164 the pipeline: audio loading, the classifier,
embedding extraction, diarize_segments
The graph is a tree: _transcribe_media imports nothing local, _cluster takes
only _try_import from it, _diarize imports from both. All 13 top-level
definitions verified AST-identical to HEAD, and an AST scan confirms the
three module constants travelled to the modules that use them.
transcribe_fw.py now imports get_media_duration from _transcribe_media
rather than through _transcribe_diarize. Ruff removed that re-export as
unused and broke the import; running the program is what caught it, and
naming the owning module is the correct fix under the no-barrels rule.
Verified: transcribe_fw.py /nonexistent.wav still exits 2 and --help exits
0; 63 tests pass at 100% line and branch on all three modules; 338 pass in
the directory. Over-cap files 33 -> 32, and no Python file is over the cap
any more - the remaining 32 are 29 shell, 2 kotlin, 1 dart.

The largest untested Python file left in the repo, at 356 lines against the
cap. Tests land first so the split that follows is verified against tests
that predate the seam.
63 tests: duration probing through both ffmpeg paths, the transcode fallback
and temp-file cleanup, audio loading's three outcomes, linear resampling,
cosine k-means, the ECAPA classifier loader, per-segment embedding
extraction, and diarize_segments end to end.
numpy is real here, not a double. It is a declared dependency, and the core
of this file is clustering maths - assertions against a mocked numpy would
prove nothing about whether two speakers actually get two labels. The
_try_import seam passes numpy through while stubbing torch and speechbrain,
so the tests still run in CI with neither installed. The clustering tests
assert real properties: two opposed groups separate, magnitude is ignored
because the metric is cosine, and a fixed seed reproduces.
The last three coverage gaps were _load_audio's ffmpeg fallback in both
outcomes, the minimum-slice widening, and the zero-iteration k-means branch.
Split across six test modules after two intermediate arrangements went over
the cap, and one move silently broke a test by separating it from its
doubles - caught by the test count holding at 63 through every rearrangement.
338 tests pass in the directory, up from 275 by exactly the 63 added.

_transcribe_progress.py 91 _run_progress_loop, _format_progress_line,
and the two constants only they use
transcribe_fw.py 236 argument parsing, model loading, diarized
output writing, main
All 8 top-level definitions verified AST-identical to HEAD, and an AST scan
confirms neither module references a name it does not bind - which is what
caught that the two progress constants and the hhmmss import had to travel
with the loop. transcribe_fw.py no longer imports time.
The progress tests now patch _transcribe_progress, including its sys.stderr
and time references, since that is where the loop resolves them.
_resolve_device_and_compute stayed behind, so its test still points at
transcribe_fw.
Verified: --help prints the full usage and a missing input returns exit 2,
the code transcribe.sh branches on; 32 tests pass at 100% line and branch on
both modules; 275 pass in the directory. Over-cap files 34 -> 33.

transcribe_fw.py is 302 lines against the cap and was untested. Tests land
first, in their own commit, so the split that follows is verified against
tests that predate the seam.
32 tests: argument parsing and its FW_* environment defaults, device and
compute resolution, the progress line, the transcription loop, model
loading, diarized output writing, and main()'s three exit paths.
faster_whisper is reached only through _try_import, so patching that seam
covers every path without the package installed. _format_progress_line is
tested directly rather than through the loop - it is pure, so the percentage
clamp, the ETA, and the suppression of an ETA longer than a day are each
assertable without a model.
The last coverage gap was _try_import itself, which every other test
patches; it is now exercised directly in both directions.
Split across three test files because a single pipeline module reached 321
lines - over the cap this work exists to clear. 275 tests pass in the
directory, up from 243 by exactly the 32 added.

Split along the natural seam now that the file is fully covered:
_transcribe_probes.py 177 _try_import, the four dependency probes,
generate_sine_wav, prepare_model, test_cuda
transcribe_helpers.py 142 the eight _handle_* functions and main()
All 18 top-level definitions verified AST-identical to HEAD, and an AST
scan confirms neither module references a name it does not bind.
transcribe.sh is untouched - it invokes tools/transcribe_helpers.py by
path, and that path still exists with the same name and executable bit.
The CLI tests' patch targets did not move either, because main() dispatches
to names imported into its own namespace.
Verified by running every subcommand and reading the exit status directly,
since those codes are the contract transcribe.sh branches on:
python-version 0, check-faster-whisper 7, check-ctranslate2 1,
check-diarization 0, deps-installed 0; generate-wav writes the same
96044-byte WAV as before the split. 41 tests pass at 100% line and branch
on both modules; 243 pass in the directory. Over-cap files 35 -> 34.

transcribe_helpers.py is 289 lines against the 250-line cap and was
completely untested. Tests land first, in their own commit, so the split
that follows is verified against tests that predate the seam.
Left at its current path rather than moved under python_pkg/: transcribe.sh
invokes it by path inside a dedicated ML venv, and transcribe_fw.py imports
two siblings by bare name, so the closure is five files (1236 lines), not
three. Tests go in linux_configuration/tests/ instead, whose conftest
already puts standalone script directories on sys.path - the same
arrangement the usage_report work used, and still collected by CI.
The ML dependencies are never installed in CI and the module reaches them
only through _try_import, so patching that one seam covers every probe in
both directions. An AST scan at every nesting level confirmed there is no
other path to them: the only direct numpy imports sit under TYPE_CHECKING.
41 tests, 100% line and branch. The last gap was the dispatch guard at
line 284, unreachable through the CLI because argparse's choices list and
the dispatch dict carry the same eight commands; covering it by admitting a
ninth choice also documents why the guard is there.
Split across four test files because a single module hit 291 lines - over
the cap this work exists to clear.
Verified: python-version prints 3.14, check-faster-whisper exits 7 with no
ML deps present, generate-wav writes a 96044-byte WAV; 243 tests pass in the
directory, up from 202 by exactly the 41 added.

Documented as "kept for backwards import compatibility", it had zero
production callers - only its own two tests. Removed the function, those
two tests, and the pathlib.Path import that only its signature used.
_SEC_PER_DAY stays: two live callers remain at _usage_report_run.py:135
and :181, so only the function was dead, not the constant.
Verified: usage_report.py --help exits 0 (the unit tests stub subprocesses,
so only a real run proves the import graph), 202 tests pass, and
_usage_report_run.py holds 100% line+branch coverage after removing both
the code and the tests that covered it.

The entry point now holds only the parser, mode dispatch and main. Three
modules take one concern each: _usage_report_logs (where the logs are,
the state file, per-day segment planning), _usage_report_emit (preflight,
stdout, clipboard), _usage_report_run (the two run paths and the
aggregation they drive).
Verified by the 100%-coverage tests from the previous commit. An AST
comparison of all 22 top-level defs and classes reports 22 identical, 0
mismatches.
All four modules hold 100% line+branch. 204 tests before and after. Both
CLI modes were run against the machine's real logs, which is the check
the unit tests cannot make: they stub the collaborators, so only a real
run proves the new import graph resolves.
Two lessons, recorded because the next target is a 498-line file:
This cut was too big. Two names had to be relocated after their first
placement created an import cycle, and four modules' worth of monkeypatch
targets needed re-pointing. A smaller first slice would have been cheaper.
Patching a moved function must target the module whose namespace resolves
it - the caller's, not the one it was moved to. Getting that wrong on
_run_since made main() call the real function, which read the actual atop
logs and hung the suite rather than failing.
Three import bugs (Path and _fmt_h left under TYPE_CHECKING but used at
runtime, dataclass missing where _Aggregates landed) were caught
immediately by the coverage from the previous commit.
Over-cap 38 -> 37.

25 tests in four files, no production change - the module is
byte-identical to HEAD. Lands before the split for the usual reason.
Covers the CLI surface (every default, every flag, main's dispatch), both
run paths including the shared empty-window-means-a-full-day fallback,
_run_since's no-data path and both state-advance branches, the
clipboard/emit side (tool selection, a failing tool, no tool at all),
_preflight's three outcomes, _aggregate_segments with a gap day and with
a present-but-empty log, and _log_descriptions.
Also covers _compute_window, which turns out to be dead: a shim
documented as "kept for backwards import compatibility" with zero callers
anywhere in the repo. Tested rather than deleted here, since removing it
is a behaviour change that does not belong in a coverage commit - but it
is a deletion candidate.
185 stmts / 44 branches, 0 missed. Directory: 179 -> 204 passing.
No suppressions: mypy rejected a `list.append(...) or 0` lambda, replaced
with a real closure; ten ruff S108 findings on hardcoded /tmp paths became
/nonexistent sentinels, which is more accurate anyway since those paths
are never opened.
Written as two files of 273 and 282 lines, then split to four under the
cap before committing - the DropZone lesson from earlier today.

Lifts the atop subprocess machinery into _usage_report_atop.py: running
atop, streaming its parseable output, building/caching the atop_agg C
helper, and reading its TSV. What stays is record parsing, epoch windows
and per-day merging.
Verified by the 100%-coverage tests from the previous commit. An AST
comparison of all 16 functions against HEAD reports 16 identical, 0
mismatches.
_usage_report_render.py imported _run from the parsing module; it now
imports from the module that owns it. That is the same re-export barrel
the last split shipped and had to fix in a follow-up - caught in the same
commit this time. usage_report.py needed no edit at all.
Both modules hold 100% line+branch (94/28 and 130/34, 0 missed). 179
tests before and after; the five new test files collect 8+6+4+14+5 = 37,
which is last commit's 36 plus the one re-homed out of
test_usage_report_modes.py, where it referenced a constant that had
moved out from under it.
The two test files added last commit were themselves over cap (373, 272)
so they are split five ways here - the DropZone lesson from earlier
today, where a lint fix silently added an over-cap file.
Ran the program: a real report from today's logs, through the native
atop_agg path, which is precisely the code this commit moved.
Over-cap 39 -> 38.
