72a5e28456 Track poker-stakes so the file-length cap can reach it
The directory has existed on disk with 58 untracked files, four of them over
the 250-line cap. An untracked file is invisible to every pre-commit hook, so
those violations could not be fixed or gated while it stayed that way -- and
its CI workflow was untracked too, so nothing ran against it.

Landed with its already-written evidence artifact and a contract, since this
crosses the 4-file threshold.

Verified before staging: 58 plain text source/config files, no binaries, no
node_modules, no build output. npm run check passes -- typecheck, eslint
--max-warnings 0, and 220 tests at 100% statements/branches/functions/lines.

Splitting its four oversized files is deliberately a separate commit.

e6e0ba5ab3 artgate: diffusion + 3D routes, full vector coverage, and the margin gate

Closes the remaining bake-off cells. The phase's real result was not a route
score but a MISSING GATE.

All twelve SDXL icons measured 100% opaque coverage -- square tiles with no
sprite silhouette -- and passed every gate in the harness. Gate-pass was
measuring pipeline hygiene, not usability. MARGIN_TOO_SMALL inverts the table
from a meaningless 12/12/12 tie to:

    diffusion   0/12      (every output full-bleed)
    vector     10/12
    procedural 11/12

The two non-diffusion failures were true positives in MY shapes, not gate
error: the procedural sword pommel ran off the bottom edge and the vector meat
bone clipped the top. Both fixed; both routes back to 12/12.

Diffusion recovers to 12/12 with flood-fill background removal, but visual
inspection shows the fill eats into the art (bone reduced to a fragment, sword
nearly erased). Reported as inadequate rather than shipped -- proper matting is
needed before route (b) is a usable pipeline.

Blender exits 0 even when its embedded script raises: BLENDER_EEVEE_NEXT does
not exist in 5.2, and the failure produced a clean exit and no file. render()
now asserts the output exists, or the route would report phantom successes.

Model gating verified at execution time, never recalled: SDXL base and
nerijs/pixel-art-xl are ungated, FLUX.1-dev is gated=auto, and
runwayml/stable-diffusion-v1-5 now 307-redirects.

The finishing stage now generalises across three continuous-tone sources
(SVG raster, Blender render, SDXL): each is 0/N raw and N/N finished.

Verified: 114 tests, 100% branch coverage on 13 modules, zero suppressions,
all hooks pass. Note: a local pytest run masked a missing branch that the
pre-commit hook caught -- the hook's run is authoritative.

691a228499 artgate: procedural + vector routes, and the shared finishing stage
Some checks are pending

Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Closes the two CPU-only cells of the art bake-off and builds the bridge the
diffusion cell will reuse.

Pins the bake-off to the SAME twelve subjects item-icons measured, with its
easy/hard split intact. Without this a route tested on distinctive silhouettes
beats the 6/12 baseline for free and the decision table means nothing. It also
makes the subject-routing rule falsifiable: a generator route is predicted to
lift specifically the six human-prior failures, and if it does not, the rule is
recorded as wrong.

Route (a) procedural: all twelve subjects drawn deterministically from a
7-colour locked palette. Every shape gets a distinguishing feature up front,
because item-icons measured that plain primitives read as placeholders however
correct the geometry is. Machine gate: 12/12 -- which proves "not malformed",
NOT quality. A procedural generator satisfies palette/alpha/canvas constraints
trivially; the human contact sheet is the real verdict.

Route (d) code-as-art: SVG emitted as text and rasterised by rsvg-convert, so
no new Python dependency (cairosvg/svgwrite stay absent).

The structural finding, measured on real rasteriser output rather than a
synthetic stand-in: raw vector renders pass 0/5 -- every one fails
ALPHA_NOT_BINARY, most also TOO_MANY_COLORS. After the finishing stage, 5/5.
Continuous-tone routes are therefore GENERATORS FEEDING A FINISHER, not
pixel-art generators. finish.py binarises alpha before quantising colour,
mirroring the gate order: quantising first blends transparent pixels' arbitrary
RGB into the palette.

Verified: 92 tests, 100% branch coverage across all ten modules, zero
suppressions, all hooks pass. The PLR2004 lint refactor was confirmed
pixel-neutral by byte-comparing all 12 icons before and after (12/12 identical).

da8ca6d827 artgate: deterministic exit-code gates for generated game art
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Adds the route-independent spine of the planned art-generation bake-off: a
harness that decides whether generated art is well-formed, so "non-sloppy"
becomes machine-checkable instead of a judgement call.

Findings that shaped the design, all measured rather than assumed:

- Integer-scale invariance separates true pixel art (impurity 0.0000) from
  interpolated fakes (1.0000) exactly -- but passes trivially at scale 1, so
  it must never be trusted alone on native-resolution output.
- Gate ORDER is load-bearing. A soft-alpha image has no fully-opaque pixels,
  so an opaque-only colour count returns 0 and silently passes. ALPHA_NOT_BINARY
  now runs first and COLOR_COUNT fails closed on an empty opaque set.
- Counting must be over opaque RGB only: transparent pixels retain arbitrary
  RGB and inflated a naive RGBA count, rejecting correct art at 18/16.
- Declaring a gate was not enough to run it. hand_painted.toml shipped
  declaring SILHOUETTE_LOW_CONTRAST with no implementation, so it parsed, ran
  nothing, and reported a pass. load_spec now fails closed on unimplemented
  gates, result-only codes, and gates missing their config.

Thresholds are calibrated against 250 genuine 32x32 CC0 icons, not guessed:
p50=7 p90=13 p99=26 opaque colours; cap 32 rejects 0.0% of real art while raw
generator output measured 34403 colours. An initial cap of 16 wrongly rejected
a real DCSS icon -- re-derived from the corpus rather than nudged.

Verified: 57 tests, 100% branch coverage, zero suppressions, all hooks pass.
58/60 (96.7%) of real CC0 icons pass the full stack; both failures confirmed
true positives.

40d2c96a77 billsplit: adopt the shared palette, retire the teal seed
Some checks are pending

Last of the four drifted apps. The theme was ColorScheme.fromSeed(teal)
plus fifteen ad hoc colour literals that mostly bypassed it -- not one
widget outside main.dart read colorScheme at all, so the seed barely
affected what you saw. It now uses design_system-v0.1.0's
buildLightTheme(), and the literals that have a real theme role read it
off the scheme.

Light, not dark, deliberately: the receipt screens carry black-on-white
helper text, so inverting brightness would make it unreadable. The
Colors.black54 sites are exactly those, now onSurfaceVariant.

The error family maps cleanly -- Colors.red to error, red.shade50 to
errorContainer with onErrorContainer text on it, and the swipe-to-delete
background+icon to error/onError so the fill and the glyph drawn on it
cannot drift apart.

The four category dots (deepOrange/amber/blueGrey/teal) stay literals,
with a comment saying why: they encode which category an item is, not a
theme role, and a single-accent system has no four distinct hues to lend
them. Mapping them onto primary/secondary/tertiary would make the
categories stop being distinguishable, which is their only job. They are
tracked in nielsen-audit.md as needing a categorical ramp. Note this
decouples the default dot from the old seed -- both were Colors.teal, so
they used to match by coincidence rather than by design.

Verified: 60/60 tests, 100% line coverage across 11 lib files, analyze
clean apart from four pre-existing unnecessary_unawaited infos. A
temporary assertion pumped the real app and read primary=ffb8862e and
surface=fff6f4f3 off a live Scaffold, confirming the palette changed
rather than merely compiling. Colour literals: 15 -> 4.

The enforcer failed in both directions: nothing blocked at home, and
everything blocked at the office. The comparison was never inverted --
`metres <= threshold` was always right. Three separate causes:

Only ACCESS_COARSE_LOCATION was declared. Android 12+ fuzzes coarse to a
~1-2 km grid against a 150 m fence, so a fix taken at home routinely landed
outside it, read as AWAY, and restored every app the geofence exists to hide.
FINE is now declared and self-granted by the device owner, along with coarse
and background, re-asserted every pass so a reinstall cannot silently drop it.

There were three states but two behaviours. LOCATION_UNKNOWN applies the
identical sweep to AT_HOME -- correct fail-closed design, indistinguishable
from outside. And nothing ever requested a fix: the pass read whatever another
app happened to cache, so at the office with no navigation running the cache
was empty. Passes now acquire a fix inside a location-typed foreground
service, bounded at 20 s, and treat anything older than 30 min as no fix. That
window is deliberately longer than the 15-minute cadence; a shorter one marks
the newest cache stale on every pass of an idle phone and blocks everything.

None of it was diagnosable. `adb logcat -d -s FocusOwner:V` came back empty
while dumpsys showed 82 alarms had fired, and `run-as` is refused on the
release build device owner requires. So the pass now writes a ring-buffered
JSONL record read back in-app: reason, distance vs the fence, fix
age/provider/accuracy, curfew state, and every hidden app with the rule that
hid it. Coordinates are never recorded -- a distance is enough to debug a
geofence, and this is a home address.

Also fixed along the way:

- Hysteresis keyed off `isEnforcing`, which is true under AWAY too because
  YouTube stays hidden, so the threshold was permanently radius+hysteresis.
  It now keys off whether the previous pass was inside the fence.
- The scheduler's curfew-boundary alarms were documented but never scheduled;
  both callers invoked `scheduleNext()` bare, so 05:00 could land 15 min late.
- Installing over the app cancelled its pending alarms, so `adb install -r`
  silently stopped enforcement until someone opened the app. MY_PACKAGE_REPLACED
  now re-arms it, verified on device without launching the app.
- A wrong-typed log record threw instead of being skipped, and the exception
  escaped far enough to leave the page stuck busy -- which disables the
  release-device-owner button, the one control that must work when everything
  else has gone wrong.
- `lib/enforcement.dart` was a second decision layer with no always-blocked
  concept, cited by KDoc as pinned by a `PolicyParityTest` that never existed.
  It would have made the new screen report YouTube visible while it is hidden.
  Deleted; the UI renders the Kotlin record rather than re-deciding.
- Anchoring home accepted a stale or unknown-precision fix. A wrong home
  offsets the fence everywhere and forever, which is what produced a 766 m
  reading while standing at home.

Policy: Play Store is allowed by day (not during curfew) so infakt can be
installed and updated; the sweep is default-deny for third-party packages, so
anything installed from Play is hidden on the next at-home pass. Tachiyomi's
per-source extension apks are covered by a new prefix allowlist rather than an
exact list that goes stale whenever an extension is installed.

`export.py` stopped subtracting the allowlist from `blockable_system_packages`.
Sweepable is not hideable: that list decides which system packages are
eligible for a decision, and `isAllowed` is what protects them. Removing an
allowed system package from the sweep freezes it in its last state -- it would
have stranded Play hidden permanently the moment it was allowlisted.

Verified on the Pixel 6a: FINE granted POLICY_FIXED, `applied AT_HOME` with a
0 m distance from a +/-11 m GPS fix, YouTube/Chrome/Firefox absent from
`pm list packages -e`, Play Store, infakt, RunnerUp and all five Tachiyomi
packages present.

The network layer was the wrong place for this. Tested remotely today: opening RethinkDNS and switching off its device blocklists un-blocked YouTube in a few taps, and no device owner API can stop that -- an on-device filter app always owns its own rules.

App hiding is different. 'pm unhide' from adb shell throws a SecurityException and the package stays hidden; only the device owner can reverse it, and reaching that costs a factory reset. So the block moves there, scoped to an explicit allowlist and the home geofence.

Both whitelists are rewritten from the apps that actually exist on this phone. The old ones described the rooted Blackview. Every browser is excluded now, so at home a link does not open at all -- confirmed as intended.

LAUNCHER_PACKAGE was still the Blackview's launcher, which is not installed here. The exporter refused to render the policy twice over it -- precisely what that check is for.

The network layer stays a soft deterrent by choice: pinned and uninstall-blocked, but without lockdown, and its blocklists remain switchable.

Private DNS is implemented but ships disabled. stunnel logged zero connections from the handset across two pin attempts, so the router does not forward 853.

Shared across every repo with an Android surface (screen-locker's workout_app,
todo, dufs-cloud/app). Works against a plain release APK on a physical device
over adb — no root, no emulator, no Flutter debug connection, no app changes.

Driving an app by tapping pixel positions read off a screenshot fails in ways
that look like success. All observed in one session (2026-08-10) verifying
workout_app's Firebase restore:

* A tap aimed at a password field landed with the field unfocused. The typed
  password went nowhere and NOTHING errored — the next screenshot just showed
  an empty box. type_into/type_into_field now re-read the field and raise.
* Opening the soft keyboard moved a field from y=1572 to y=1319, so a
  coordinate captured one step earlier was already wrong. Every action
  re-resolves the element immediately before acting.
* A widget behind the keyboard reports its LAID-OUT position (1549) not its
  real one (1939) — a 390px error that taps a letter key and reports success.
  keyboard_is_up() distinguishes "absent" from "behind the keyboard", and tap
  closes the keyboard first.
* KEYCODE_BACK is a route pop in Flutter, not a keyboard dismiss: it navigated
  out of Settings and discarded typed credentials, twice. dismiss_keyboard
  tries ESCAPE then BACK and verifies via dumpsys input_method.
* `input text` inserts at the cursor, so typing over a filled field produced
  "canary@example.com321krzychu@gmail.com". Fields are cleared first.
* uiautomator returns ONLY the focused EditText nodes while a Flutter text
  field has focus, and stays that way across retries — so a naive retry loop
  never converges. Partial trees are retried and the best result kept.
* An EMPTY EditText has no text, content-desc or resource-id, so a
  "must be labelled" filter drops the very field you need to fill in. Editable
  nodes are kept regardless and addressable by position.

Ambiguity is an error rather than a silent first-match: `tap "Back"` correctly
refuses when "OFFLINE BACKUP" is also on screen.

Its own test suite caught a real bug in _escape: backslash sat inside the
escape loop, so "&" became "\\&" and a password containing shell
metacharacters would have been typed wrong.

86565bdef6 archwiki_rag: offline semantic search over the Arch Wiki
Indexes the arch-wiki-docs dump that is already on disk and exposes it
to the knowledge-rag MCP server, so Arch questions can be asked by
symptom ("why doesn't my systemd user unit see DISPLAY under i3")
rather than by page title, with no network round-trip at query time.

The one Arch-specific MCP server in the wild fetches pages over the
network and bundles pacman operations that duplicate the local yay-mcp.
This does neither: it only searches, against a local corpus.

install.sh installs its own dependencies, wires the MCP config and
registers a pacman hook so the index follows package updates. The
generated index is machine-specific and regenerable, so it is
gitignored rather than committed.

_reindex_entry runs under the knowledge-rag interpreter, where
mcp_server is importable and this repo's packages are not. Resolving
that import with importlib.import_module states the deferral outright
instead of a function-level import statement that reads as an oversight,
and the backend failure path now re-raises as SystemExit, so the
exit-code translation is explicit rather than a swallowed exception.
Both replace lint suppressions; the package carries none.

pylint runs in its own venv, so beautifulsoup4 and markdownify are
declared there too — being in meta/requirements.txt does not make them
resolvable to the hook.

cef72fbab0 syncyomi_guard: refuse a collapsed payload as the new good copy
TachiyomiSY 1.13.2 can report a restore as SUCCESS while writing almost
nothing, then sync that near-empty library up and replace the only good
copy. On 2026-08-09 a 14 MB payload holding 2182 manga became a 267 KB
stub, and the real library survived only as stale pages in the SQLite
write-ahead log.

The upstream bug is Kotlin in an APK and cannot be fixed here, so this
targets the fixable half: decode the payload, count what is actually in
it, and refuse to treat a collapse as normal drift. A pure is-it-zero
check would have caught this incident but not the harder case upstream
describes, where a restore keeps some entries and drops the rest, so the
threshold is proportional. Categories get their own rule because all
2182 manga survived the round trip and all 18 categories did not.

Adds the setup script and a runbook covering the WAL-page salvage used
to recover the library on the day.

f33fd03a16 focus_owner: keep the unhide path reachable, never hide the enforcer
setApplicationHidden drops a package from the default PackageManager
enumeration even though it stays installed=true, so a sweep querying
with flags 0 could never see anything it had already hidden. That made
packagesToShow permanently empty: measured on device, a pass following
one that hid three apps reported "hid 0, restored 0" and left them
hidden with no way back. Query with MATCH_UNINSTALLED_PACKAGES instead.

Hiding the enforcer itself is the other unrecoverable case, since it
takes the escape hatch and the trigger with it. The exporter now injects
com.kuhy.focus_owner into both the day and night allowlists so the
decision layer cannot propose it, and the runner keeps its point-of-use
skip to cover a policy asset rendered before this fix or hand-edited.

Add a [claude_usage] block showing the 5h and 7d rate-limit windows. It
reads ~/.claude/cache/limit-state/*.json, which Claude Code's statusLine
hook already writes to disk, so the data costs nothing to display: the
script only runs jq against a local file and makes no API call. Limits
are account-wide while the cache is sharded one file per project, so it
takes the newest file and ignores cwd. Percentages arrive as floats and
are truncated; a stale cache is labelled rather than shown as current,
and a rolled-over window reads "?%" instead of a misleading value.

Replace Font Awesome private-use-area icons with plain Unicode. Both
fonts named in the bar's pango string ("System San Francisco Display",
"FontAwesome") are not installed, so PUA codepoints fell through to
whatever font claimed them: ethernet rendered as a star, wifi as
Cyrillic, gpu as Hangul, disk as a chess pawn. Emoji resolve through
fontconfig consistently, which the pre-existing volume block already
relied on, and need no change to ~/.config/i3/config.

Remove the bluetooth, battery, wifi, activitywatch, warp and
network_monitor blocks: this desktop has no BT adapter, no battery, no
wireless interface, and no warp-cli. This also removes a rendering bug,
since activitywatch_status.sh and warp_status.sh were interval=persist
yet emitted three lines per update, leaking their colour line into the
bar as literal "#FF0000" text.

Fix ethernet reporting "down" on a live wired link:
find_ethernet_interface returned the first non-loopback interface, which
with docker installed is a br-* bridge (permanently down, and sorted
before enp*). It now requires a real /sys/class/net/*/device and prefers
an interface that is up.

Tests drop the assertions and fixtures for the removed blocks and add
claude_usage coverage (fresh, warn, critical, stale, rolled-over, null
reset, unparsable, missing dir), a guard that removed blocks cannot
return, a repo-wide check that no block script uses a PUA codepoint, and
an ethernet physical-NIC regression check. The fork budget is asserted
against a populated cache directory, which caught a stat call inside the
scan loop that cost one fork per cached project (170 -> 2 execs).

Haunting, Normal and Crusade scale enemy hp and speed, the survivor's
health, your income, and the length of the night. Normal is exactly 1.0 on
every multiplier — it is the identity tier, which is what lets every
existing raw-value assertion keep passing untouched.

Enemy speed now derives from a single helper, so difficulty and frenzy
compose in one place rather than fighting at three call sites.

Also fixes a bug this surfaced: handleRestart ignored the selected tier, so
restarting after choosing Crusade silently reverted to Normal. The
react-hooks purity rule flagged Date.now() in the new handler, and
extracting restartSeed() exposed the omission.

Endless mode is deliberately left out — fmtTime(Infinity) renders
Infinity:NaN, which would cost a guard plus tests for a mode whose only
content is the same game but longer.

README rewritten for all four features, including the reversal of its old
placement promise.

2d66bfdd61 reverse_survivors: director powers — ambush, frenzy, rift
Ambush drops a unit beside the survivor, inside the ring its kiting AI
would otherwise keep clear. Frenzy drives the whole horde faster and harder
for six seconds. Rift pins every spawn to one edge for ten, so you can mass
a flank instead of scattering.

This reverses the README's old promise that placement is never yours to
choose. The interesting decision turned out to be what a placement is
worth, not being denied one — so placement is purchasable, never free: a
premium for Ambush, a cooldown and a commitment window for Rift.

A shared spendPower gate covers cooldown and affordability for all three,
so the next power costs no new branches. EDGES became a Record keyed by a
finite union rather than an array: under noUncheckedIndexedAccess an array
index is possibly-undefined and would force an unreachable fallback.

The unpinned spawn path still draws the same RNG values in the same order,
verified against the old implementation across 50 seeds — existing seeded
replays are unchanged.

145 tests, 100% coverage.

43b63ac266 reverse_survivors: survivor status effects (slow, suppress, bleed)
The warden mires, the artillery stifles, the leech unknits. All three need
contact, so a survivor that kites cleanly takes none of them — debuffs
punish positional failure rather than taxing existence.

isOn/factor are written as arithmetic rather than comparisons:
Math.min(1, Math.ceil(t)) is 1 while a timer is live and 0 once it expires,
so consumers multiply instead of branching. The whole status module
therefore contributes zero branches, which is what makes the 100% gate
affordable for a system this cross-cutting. Statuses are applied
unconditionally too; a 0-duration spec is a provable no-op.

applyStatus uses Math.max, so re-applying refreshes rather than stacks.
That caps a horde's total lockdown at one duration by construction — a
structural guarantee, not a tuned number.

123 tests, 100% coverage. Branches 117 -> 119: the draw halo gate and the
snapshot chip filter. The status logic itself adds none.

f0712d3854 reverse_survivors: add splitter, artillery, warden and the leech boss
Splitter dies into three rushers, so killing it creates pressure rather
than relieving it. Artillery outranges the survivor (460 vs its 260) and
holds station beyond reach, the first unit its kiting AI cannot answer.
Warden outruns it. Leech is a third boss.

Two new EnemySpec fields carry this: spawnKind generalizes the hivemind's
hardcoded 'rusher' minion, and splitCount drives on-death splitting.
split() is called unconditionally and is a no-op at splitCount 0 — a guard
branch would need two tests to satisfy the 100% gate and buys nothing.
Child offsets are fixed rather than drawn from the RNG, so seeded replays
are unchanged.

105 tests, 100% coverage. Branch count stays at 117: this adds none.

a96605dc4b Wire the enforcement decision to the DPM hide call
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
The decision layer and setApplicationHidden were both built and tested but
never connected -- the service logged a tick. Joining them meant porting the
decision to Kotlin, because a background Service has no Flutter engine and
starting one per alarm to answer a pure question would be slow and would add a
failure mode at precisely the moment enforcement has to be reliable.

That duplication is only safe if the two cannot drift, so the Kotlin suite
restates the Dart cases one for one rather than testing something adjacent. It
was checked for vacuity by asserting the hidden set contained a package that is
not installed: 13 tests completed, 1 failed, and it was the right one.

Show is applied before hide. If a pass is interrupted -- process killed, device
sleeps -- the half that ran is the half that restores access rather than the
half that removes it. The launcher, the protected prefixes and the app's own
package are re-checked at the point of use as well as in the policy, because
hiding the dialer would be unrecoverable from the device itself. An unreadable
policy yields no decision rather than an empty allowlist, which would hide
every app. The next run is scheduled in a finally, so an enforcement bug costs
one tick instead of ending the chain.

Note for the next session: JDK 26 is the system default and breaks the Android
jlink transform; the Gradle tests need JAVA_HOME=/usr/lib/jvm/java-21-openjdk,
which is what Flutter itself uses.

NOT verified on device. Unit tests cover the decision, but no real hide/show
pass has been observed -- a managed profile was created and the app made
profile owner, and the UI confirmed the policy loaded, but the session ended
before a pass was triggered. The profile was removed and user 0 verified clean.

cc804dd311 Run enforcement from exact alarms, and re-arm it before first unlock
The decision layer needed a runtime. A polling loop was the obvious design and
the wrong one: Doze can skip a poll indefinitely, and skipping the 05:00
boundary leaves the curfew allowlist applied into the morning -- the user finds
their banking app missing with no obvious cause. The transitions are known
ahead of time, so they get exact alarms. The service wakes, applies, schedules
the next run and stops rather than sitting resident.

BootReceiver takes LOCKED_BOOT_COMPLETED as well as BOOT_COMPLETED, because the
latter does not arrive until first unlock. That is not theoretical: this phone
sat at RUNNING_LOCKED for minutes after an earlier reboot in this session, with
no network and no app able to start. Relying on BOOT_COMPLETED alone freezes
enforcement state across a reboot -- safe for hiding, not for unhiding, which is
the direction that strands you without a dialer. The schedule is re-armed
before unlock; the pass itself waits until storage is readable.

The first on-device run logged "exact alarms not permitted", and dumpsys showed
what that costs: window=+11m14s, maxWhenElapsed=+25m51s, so a 15-minute
fallback could slip to 26 minutes. SCHEDULE_EXACT_ALARM is user-revocable and
denied by default on Android 16; USE_EXACT_ALARM is the permission for apps
whose function is acting at specific times, and is granted at install. After
the change: window=0, exactAllowReason=policy_permission, whenElapsed equal to
maxWhenElapsed.

The service reports "not DO/PO - no enforcement applied" and does nothing when
unprovisioned, rather than failing quietly, and a failure inside a pass cannot
stop the next run being scheduled -- an enforcement bug should degrade one tick,
not end the chain.

Not yet wired: the service logs a tick rather than calling setApplicationHidden
with the decision. Both halves are tested; joining them is next.

d0fcda3a47 Provision home coordinates out of git; layer the workout signal; drop the test hook
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
The geofence needs HOME_LAT/HOME_LON, but those say where I live, so the
committed policy asset is generated with --redact-home and the real values are
pushed to app-private storage instead. push_home_location.sh greps
config_secrets.sh rather than sourcing it -- that file holds other secrets and
this script has no business evaluating them -- and refuses the shipped
REDACTED_* placeholder with a message naming the file to fill in, rather than
writing whatever the parse happened to land on.

Private storage was chosen for its lifetime as much as its permissions: it does
not survive an uninstall, so reinstalling forces re-provisioning instead of
silently inheriting a stale home. The default umask left the file 666, so the
script chmods it 600; the shell user gets Permission denied, and the
/data/local/tmp staging copy is removed after the transfer.

Every read failure returns null rather than throwing. Null reaches the
enforcement layer as location-unknown, which already fails closed into
enforcing -- so a corrupt coordinates file cannot become an unlock, and cannot
crash the service either.

Workout detection replaces a root-only SQLite read of StrongLifts' private
database. The manual source is time-boxed rather than a plain toggle, because a
workout mode left on by accident is indistinguishable from having no exception
at all. The guarded wrapper catches broadly and times out: nothing about a
workout probe failing should be able to stop enforcement running. The combined
source can name which signal opened the exception, so the UI can explain an
unlock rather than presenting it as magic. Only the two sources verified to
exist on this device will be wired -- com.kuhy.workout_app exposes nothing
readable and org.runnerup is not installed.

HideTestReceiver is deleted. It proved setApplicationHidden persistence, which
is what it was for, but it applied policy from an exported receiver and that has
no place in a build that will later hold device owner. Confirmed absent from the
rebuilt and reinstalled APK.

1b7958143d Prove DPM app-hiding survives a reboot; build the enforcement decision layer
The whole Device Owner design assumed setApplicationHidden persists across a
reboot, and that had never been tested -- while both shell primitives were
measured to be cleared by one. Settling it looked like it needed a factory
reset. It does not: a managed profile is removable and takes its profile-owner
grant with it, so the DPM API can be exercised and then erased.

  pm create-user --profileOf 0 --managed   -> user 10
  dpm set-profile-owner --user 10 ...
  ... hide, reboot, re-check ...
  pm remove-user 10

hidden=true before the reboot, hidden=true after, agreed by dumpsys and by the
DPM API itself. Afterwards: Device Owner Type -1, no restrictions, and Chrome
in user 0 untouched.

Scope limit, stated because it is easy to overclaim: this proves the API's
hidden state persists under PROFILE OWNER inside a work profile. It does not
prove a DEVICE OWNER can hide a given app in user 0, which is what the design
actually needs -- DO there additionally cannot touch the launcher, the default
dialer/SMS/IME or packages the system deems critical, and the call can return
false silently. That must be tested in the first minute after provisioning,
while clearDeviceOwnerApp() is still a cheap exit.

On top of that, EnforcementDecision turns policy plus conditions into a
hide/show set. It is a pure function, so the whole decision layer is tested
without a device, a clock or a location provider.

packagesToShow is deliberately the complete allowed set rather than a delta.
Failing to hide something is a mild disappointment; failing to UNHIDE strands
the user without a dialer or a bank at 09:00 because the phone rebooted during
curfew. Applying the full set on every evaluation makes a missed run
self-repairing, which matters because BOOT_COMPLETED does not fire until first
unlock -- observed directly, the phone sat at RUNNING_LOCKED for minutes after
a reboot with no network at all.

The workout exception is expressed as packages rather than domains. The rooted
system unblocked youtube.com in a hosts file; hiding an app cannot target a
domain, so the package set is derived from the configured domains and config.sh
stays the source of truth for intent.

Signal sources were checked on the device before being built: StrongLifts is
granted health.WRITE_EXERCISE and Health Connect is installed, so that path is
viable; com.kuhy.workout_app exposes only a MainActivity and Flutter
boilerplate; org.runnerup is not installed here at all. Only the two that can
actually produce a signal will be wired.

HideTestReceiver is temporary and must be deleted before any provisioned build.

143d260c1c Park phone DNS filtering: Private DNS fails closed, so the PC cannot host it
Some checks failed
Pre-commit checks / pre-commit (push) Has been cancelled
Shell tests / shell-tests (push) Has been cancelled
Shell tests / arch-tests (push) Has been cancelled
Measured on the Pixel 6a, twice: with private_dns_mode=hostname and the
resolver unreachable, `ping example.com` returns "unknown host". Android's
Private DNS does not fall back to the carrier's resolver -- hostname mode is
RFC 8310's strict profile, and failing to establish TLS on 853 is a hard error.

So a resolver living on this PC means "PC off" equals "phone has no internet",
not merely "no filtering". That is disqualifying for a daily driver, and it
disqualifies the whole home-hosted delivery path regardless of how well it
works while the machine is up -- which it does; it was verified end to end.

DNS_TRUSTED_DOT_HOST/IPS go back to empty, which restores the previous enforcer
behaviour byte for byte. No code revert is needed, which is exactly why the
flag was built to default empty.

Two things found while testing are worth keeping. The nftables input chain is
policy drop and admitted only ssh over wg0, so binding stunnel to the tunnel
address was not sufficient on its own: ICMP passed while TCP 853 was dropped,
which presents confusingly as "ping works but the port does not". That rule is
now added explicitly and scoped to wg0. And setup_phone_wireguard.sh automates
the client setup the tunnel needed, verifying handshake, reachability and DNS
rather than assuming success, and deleting the pushed private key afterwards.

The deeper reason the home endpoint could not work even with the tunnel up:
dns.kuhy.duckdns.org resolves to the public IP while stunnel listens only on
10.8.0.1, and with AllowedIPs=10.8.0.0/24 that routes outside the tunnel to a
closed port. Android never opened a connection at all. Split-horizon DNS does
not fix it either, since on mobile data the phone uses the carrier's resolver.

Research also ruled out the hosted-hybrid option that looked most attractive:
no provider can ingest a 185k-domain list (NextDNS none, AdGuard 1-5K, ControlD
10K), and the free tiers fail OPEN -- they stop filtering past 300k queries a
month while still resolving, which for a self-control tool is the worst failure
mode available. Details and the remaining options are in the parked doc.

The stunnel endpoint is left running deliberately: WireGuard-only, verified
unreachable from LAN and WAN, and it makes the next attempt testable
immediately. Removal commands are documented.

e3d5e1dd18 Serve the blocklist over DoT and hand the policy to the app as an asset
Two gaps stopped the unrooted path working end to end. The phone had no way to
read the focus policy, and the blocklist was only reachable as a hosts file or
over plain UDP/53 on the LAN -- while the rooted enforcer actively rejected
every DoT connection, so a self-hosted resolver could not have worked even if
one existed.

focus_owner now loads a generated policy.json instead of hardcoding anything,
so config.sh stays the single source of truth across Python, shell and Kotlin.
The committed asset is rendered with --redact-home and a test fails if home
coordinates ever appear in it. An unknown schema_version is rejected outright:
silently accepting a newer schema means enforcing a policy the app has misread,
and a misread allowlist is one that blocks the dialer.

dns_enforcer.sh rejected ALL port 853 traffic and pinned Private DNS off, every
20 seconds. That is right when DoT is a bypass channel and exactly wrong when
DoT is the enforcement channel, which is what an unrooted phone needs -- it has
no hosts file to fall back to. With DNS_TRUSTED_DOT_HOST set it now ACCEPTs the
trusted resolver before the blanket REJECT, and pins Private DNS to that
hostname so the user cannot pick an unfiltered one. Rule order is load-bearing:
iptables takes the first match, so an ACCEPT appended after the REJECT would
never be reached. expected_rule_count() counts the new rules, because a
mismatch there makes chain_intact() rebuild the chain every 20s -- a silent
fork storm that also drops the connection each time. With the variable empty
the behaviour is byte-identical, so the rooted phone is untouched until this is
deployed.

setup_dot_resolver.sh terminates DoT with stunnel rather than Caddy: DoT is a
raw TLS stream and stock caddy:2.8 has no layer4 module, so using Caddy would
have meant an xcaddy rebuild of a container serving five live sites. It reuses
the certificate Caddy already renews, so nothing competes for port 80. It binds
to the WireGuard address, not 0.0.0.0 -- a public DoT endpoint is an open
resolver, and over the existing tunnel it needs no port-forward, no firewall
rule and no rate limiting. Verified: example.com resolves, pornhub.com returns
0.0.0.0, TLS 1.3 against the LE cert, and both the LAN and public addresses
refuse.

The Device Owner checklist is planning only. Checking the device rather than
the config settled the one open risk: Google Wallet is not installed and no NFC
payment default is set, so the unconfirmable tap-to-pay question does not apply
here. The same check found that Aegis, MS Authenticator, Oracle IDM and PKO IKO
are absent -- they are in config.sh's whitelist, which describes the rooted
phone, not this one.

f636d2b21b Make focus policy and blocklist usable without root; fix workout CDN unblock
phone_focus_mode is built for a rooted phone: the hosts layer is a read-only
bind mount over /system/etc/hosts, chosen so that even root-in-a-terminal
cannot overwrite it. None of that ports to a stock locked device. This splits
out the parts that are device-independent so one policy can drive both.

python_pkg/focus_policy parses config.sh rather than copying it, so the shell
config stays the source of truth and the two cannot drift. It rejects the
shipped REDACTED_* coordinate placeholder instead of defaulting to (0,0),
which would move "home" to the Atlantic and quietly disable the location gate.

blocklist.py converts the hosts file to domains for a DoT resolver or a local
VpnService. Three properties of the real 194k-line file make the obvious parser
wrong, and all three are handled: generate_hosts_file.sh *comments out*
deliberate unblocks rather than deleting them, so stripping '#' re-blocks
facebook/messenger/linkedin/4chan; the StevenBlack header carries loopback and
IPv6 housekeeping that would blackhole localhost; and ~1060 upstream annotation
tokens ('#[adware.zeno]', '"spam') render as address=/"spam/, which makes
dnsmasq refuse to start -- taking DNS down rather than blocking anything.
Verified with dnsmasq --test over all 185681 generated domains.

strip_workout_hosts.py had the same class of bug on the live rooted phone:
exact set membership meant the allowlisted googlevideo.com never matched the
dynamic r*---sn-*.googlevideo.com hosts YouTube actually streams from, so the
workout unblock was only partly working. Now suffix-matched (17 lines stripped,
was 14). The three new tests were checked against the original code in a
throwaway worktree; two of them fail there, so they pin the fix rather than
passing vacuously.

focus_owner is a device-owner app that deliberately does nothing yet. It ships
clearDeviceOwnerApp() implemented and tested first, because dpm
remove-active-admin does not work on a device owner: an app that locks the
device down before proving it can let go leaves a soft-brick recoverable only
through fastboot on a locked bootloader. Built, installed and launched on the
Pixel 6a; dumpsys afterwards confirms Device Owner Type -1 and no user
restrictions, i.e. the phone is unchanged.

Measured while scoping this, and not yet reflected in any enforcement code:
on Android 16 both pm suspend and pm disable-user are cleared by a reboot, so
shell-level app blocking is per-session only. setApplicationHidden is assumed
to persist under Device Owner but is untested.

9dd9aeb50e Fix the 11 shellcheck findings that kept CI red since b83ce5d
"Pre-commit checks" has failed on every push since b83ce5d removed
shellcheck's --severity filter. The findings never appeared locally: CI
installs an older shellcheck than this machine, and 0.11.0 no longer emits
SC2002/SC2015/SC2119 at all. Reproduced by fetching shellcheck 0.9.0, which
matches CI's output exactly, and verified against both versions.

SC2015 x6 -- rewrote `A && B || C` as an explicit if. Each keeps its trailing
`|| true`, so a failing side effect still cannot abort the caller under set -e.
The first draft dropped it in run_phone.sh; a review pass caught that and it
was restored, since that call is the last statement of a function.

SC2119 x3 -- require_imagemagick and adb_select_device take an OPTIONAL first
argument, so the bare calls were already correct. Following shellcheck's
literal advice and passing "$@" would forward the script's own arguments as a
tool preference, which would be a real defect. Passing an explicit "" states
the same intent without changing behaviour, confirmed by running both forms.

SC2002 x2 -- `cat FILE | tr ...` becomes `tr ... < FILE`, keeping 2>/dev/null
so a missing file still yields an empty string.

No suppressions, no --severity filter, no exclusions added. Verified: 0
findings under both shellcheck versions, `pre-commit run shellcheck
--all-files` passes, test_adb_common 13/13, test_boot_repair 31/31, 1193
Python tests at 100% coverage.

1b43ba093c mtk_root: build the rooting toolkit before the phone lands
Some checks are pending

Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Prep for a Ulefone Armor X12 Pro (MediaTek MT6765) that has not arrived,
validated read-only against the Pixel 6a that has.

Partition discovery never hardcodes boot vs init_boot. It reads
/dev/block/by-name/, derives the slot scheme from observed _a suffixes, and
picks the ramdisk carrier by preference order init_boot then boot over what is
actually present. The AOSP launch-version rule explains why that ordering is
right; the code consults the filesystem, not the API level. One path therefore
serves both a Pixel (no init_boot, falls to boot_a) and a 13-launch MediaTek
device (init_boot_a taken). Patching the wrong one yields a phone that will
not boot.

Classification refuses rather than guesses: ULEFONE needs a positive MediaTek
signal AND a vendor match, with no "not a Pixel therefore Ulefone" fallback.
Carrier lock is always reported UNDETERMINED, because sys.oem_unlock_allowed,
ro.oem_unlock_supported and settings global oem_unlock_allowed read identically
whether a device is carrier-locked or merely has the toggle off; asserting a
negative would wrongly rule out a path.

No flashing script, deliberately. Automating irreversible partition writes
defeats the confirmation steps that catch a wrong partition or missing slot
suffix.

Three bugs found by running the code rather than only linting it:
- SIGPIPE: `adb version | head -1` under pipefail exited 141 and killed
  00-preflight.sh mid-run
- 20-dump-stock.sh exited silently when no recon had run, because find on a
  nonexistent cache dir fails under set -e
- the read-only static scan had a hole: stripping all quoted strings to avoid
  false positives on printf text also hid `adb shell "reboot bootloader"`.
  Now only printf/echo/cat arguments are stripped, and a negative self-test
  asserts the scan fails on injected commands

Also narrowed a world-writable udev catch-all (idVendor=="*", MODE="0666")
that granted every local process read/write access to every USB device;
commented with a backup, adb connectivity re-verified afterwards.

Validated: 58/58 offline fixture tests; 00-preflight.sh HOST READY (12/12);
10-recon.sh read-only against the Pixel reports PIXEL, boot_a, A/B, no
init_boot, path C-or-D indeterminate, with the device unchanged afterwards.
Untested and labelled as such in READY.md: the init_boot branch on real
hardware, mtkclient over BROM, and the whole flash/verify sequence.

Some checks failed

Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
billsplit CI / quality (push) Has been cancelled

The shellcheck hook ran with --severity=warning, so info- and style-level
findings never failed a commit. 222 had accumulated across 94 of 244 shell
files. They were not all style noise -- six were bugs:

  - Five scripts in single_use/misc/testsAndMisc-bash/ sourced
    $SCRIPT_DIR/../../lib/common.sh, one directory too shallow. Nothing exists
    at that path, so all five failed at runtime.
  - setup_personal_website.sh and setup_kcd2_dice_solver.sh called usage()
    (which ends in `exit 0`) and then `exit 1` for an unknown command. The
    exit 1 was unreachable, so a typo'd subcommand reported SUCCESS.
  - Six i3blocks scripts had a `# shellcheck source=` directive missing the
    scripts/periodic_background/ path segment. The stale path had silently
    disabled source-following for all of them.
  - diagnose_arch_performance.sh word-split a newline-joined file list; when
    the find came back empty, awk got no file operands, fell through to
    reading stdin, and the diagnostic hung.
  - lib/common.sh's handle_arg_help_or_unknown ended in an unreachable
    `return 0` while documenting "Returns: 0 if handled" -- a contract no code
    path could satisfy.
  - deploy.sh's SCRIPT_DIR is reassigned by config.sh, which it sources at top
    level, and config.sh can repoint it at the on-device path
    /data/local/tmp/focus_mode. Renamed to DEPLOY_DIR.

The SC1091 bulk (81 findings) was resolved rather than silenced: .shellcheckrc
sets external-sources + source-path=SCRIPTDIR so sourced files are actually
followed and analysed. That is what surfaced the i3blocks and deploy.sh bugs.

17 `# shellcheck disable=` directives remain, each with a written reason, and
only where the finding is provably wrong: injection-test payloads that must not
expand, literal source text being grepped for, POSIX sh scripts on the phone
where arrays do not exist, and source paths that only exist at runtime.
Everything else was fixed in code.

Verified in a CLEAN worktree, not just my own tree. config.sh sources the
gitignored config_secrets.sh, which exists locally but not in a fresh checkout;
a working-tree-only check passed while ci_mirror.sh -- which lints HEAD in a
clean worktree, exactly as CI does -- failed on it.

The gate is verified to bite: a file whose only finding is SC2016 (info) fails
the hook, while the old --severity=warning gate exits 0 on it.

third_party/ is excluded -- vendored upstream, matching the prettier hook.

Not fixed, reported: check_polling_antipatterns.sh carries a pre-existing
SC2034 disable that hides a real bug -- its `patterns` array is never used, so
the checker detects nothing. Confirmed unchanged by this commit.

79829ec8a2 Diagnose the pacman first-hook stall; fix the drift that hid a stale wrapper
pacman intermittently freezes at its FIRST PreTransaction hook - 5 abandoned
transactions since 2026-07-29, stalls of 4 minutes to overnight, always fine on
retry. This investigates it and repairs the real defects found on the way.

The stall is NOT fixed, and deliberately so: no verified defect was found, so
nothing pacman-side was changed.

  - Not guard-lib. /etc/guard-lib/targets was empty, so that hook script
    provably exits in milliseconds. The failures share POSITION (first hook of
    the transaction), not identity: one stall hit the hosts hook back when that
    one ran first.
  - Not reproducible on demand. 65 real transactions (40 idle, 25 under 2.6 GB
    of memory pressure) produced zero stalls. Against the historical 4-in-56
    rate that is ~0.9% likely, so the trigger is conditional on something a
    synthetic load does not recreate. Memory pressure is untested at the load
    that actually occurred - not refuted.

So diagnose_pacman_hook_stall.sh drives real transactions with a watchdog, and
its --watch mode passively captures /proc/<pid>/{stack,wchan,syscall}, the
process tree, meminfo and PSI from the next REAL stall. No pacman-side fix
should ship before that dump exists.

Three real defects were found and fixed:

1. The deployed pacman wrapper was 19916 B against a 27510 B source, never
   sourcing the shared pacman_lock_lib.sh that makepkg_wrapper already used.
   It hid because check_pacman_wrapper() only tested that files EXIST. Both
   installers now write a drift manifest covering source AND installed hashes;
   the checker replays it with sha256sum -c and fails closed when it cannot
   verify. Manifest paths are absolute - relative ones resolve to nothing under
   systemd's cwd=/ and would have looped reinstalling forever.

2. The guard-lib migration (66c4698) was never finished here: guard-lib was
   installed with zero registered targets while the legacy hosts-guard layer did
   all the work, so every transaction ran two PreTransaction hooks and the first
   one did nothing. migrate_hosts_guard_to_guard_lib.sh registers hosts,
   nsswitch and resolved, retires the legacy hooks and units, and has a
   --rollback that was actually exercised. Plugins install to a stable path
   because guardctl records absolute plugin paths. Side effect: one hook pair
   instead of two, transactions ~5-6s -> ~2-3s.

3. "One heavy job at a time" was a rule a human had to remember. heavy_job_lock.sh
   makes the overlap impossible: one system-wide flock shared between root and
   the user (a per-user lock would give root's pacman and the user's builds
   separate locks and no exclusion at all). Wired into pacman TRANSACTIONS only
   - read-only queries stay instant - plus makepkg_capped and the coverage hook.
   Always fails open.

Two bugs surfaced only by running --rollback, both of which briefly left
/etc/hosts with no immutable flag: fg_uninstall clears +i on its way out while
legacy watchers only fire on PathModified, and `((i > 20)) && break` left the
loop body's status at 1, which under set -e aborted the rollback silently - but
only when the loop actually ran, so --dry-run looked healthy.

Not migrated: the shutdown-schedule guard (/etc/shutdown-schedule.conf does not
exist here). Not wired: Flutter/Gradle builds, which have no single entry point.

4d9f486176 billsplit: build a real APK by dropping file_picker for file_selector
billsplit had never produced an Android APK. file_picker 11.0.3 — the latest
release on pub.dev — is wedged under AGP 9 in both directions: it skips
applying the Kotlin Gradle Plugin when AGP >= 9, so with built-in Kotlin off
its own Kotlin never compiles (`cannot find symbol: FilePickerPlugin`), and
with built-in Kotlin on its buildscript leaks KGP onto the global classpath
via rootProject.allprojects, which AGP then rejects for every module.

The app's Gradle config was never at fault: android/app/build.gradle.kts and
settings.gradle.kts are byte-identical to habit_stack, home_inventory and
diet_guard_app, which all build. Only the dependency differed, so the fix is
the dependency — the toolchain stays on the house-standard AGP 9.

Ported both call sites to the official file_selector. Its save flow returns a
destination and leaves the write to the caller, where file_picker wrote the
bytes inside the plugin; that write now goes through an injectable seam
because a real dart:io future never completes inside testWidgets' fake-async
zone, so a widget test could otherwise never observe the resulting snackbar.
The test double moves from a MethodChannel mock to a FileSelectorPlatform fake
(file_selector speaks Pigeon, so a channel mock would not intercept it), and a
plain non-widget test covers the real on-disk writer to hold 100% coverage
without an ignore.

The launcher icon is now verified from the built artifact: the ic_launcher
assets unzipped from the APK render as the charcoal + gold perforated receipt,
not the stock Flutter beach. Peak build footprint is 1.86 GiB, inside budget.

Also rewrites ci_mirror.sh to run its gates in a disposable worktree at HEAD.
`pre-commit run --all-files` stashes the live tree, and in a shared checkout
that made an unrelated agent's uncommitted work collide with hook auto-fixes,
failing the push while blaming an innocent hook — and putting that work inside
a stash window, which memories/git-rules.md forbids. A clean worktree needs no
stash and is a truer mirror of CI, which never sees a dirty file.

287512f011 phone_focus_mode: reach the phone over adb without touching it
Android's Wireless debugging is deliberately ephemeral: the listener dies
when you leave the settings screen or the device sleeps, and it picks a
new random port each time. In one session it offered 35545, then 40401,
then 43781, and vanished entirely twice. Every deploy therefore started
with tapping through Settings and reading a port off the screen.

enable_persistent_adb.sh waits for any such transient window, then uses it
to pin adbd to port 5555 - the port deploy.sh has always assumed - and
installs a Magisk service.d boot script so the same happens on every boot.

The phone is on DHCP with no reservation, so the script identifies it by
MAC rather than trusting a hardcoded address: a ping sweep populates the
neighbour table and the address is looked up there. That beats a router
reservation because it needs no router access and works on any network.

One bug worth naming: the first version took the first `device` line from
`adb devices`. Pairing also leaves an mDNS _adb-tls-connect._tcp entry for
the same phone, so it reported port 5555 as reachable while nmap showed it
closed. It now matches the exact ip:port.

Verified: nmap showed 5555 closed then open across the switch; a run
against a deliberately wrong IP reported "phone moved" and connected; and
after `adb reboot` the script connected with no arguments and no
interaction, with /proc/uptime at 149s and service.adb.tcp.port reading
5555, so the boot script really ran. shellcheck clean.

Trade-off accepted by the user: adbd on a fixed port is reachable to
anything on the LAN, though it still requires an authorised key.

5b654fc286 app_icons: finish the epopeja_karta entry; whitelist it on the phone
Registers the new Epopeja character-sheet app (~/epopeja_karta, its own
repo at kuhyx/epopeja_karta) in the shared icon family and lets it run
under focus mode.

The quill-nib glyph and the initial APPS entry already landed in c600760
("Move billsplit Flutter app into the monorepo"), which picked them up
from the working tree while they were still in progress. This commit adds
what was still outstanding:

- phone_focus_mode/config.sh: whitelist com.kuhy.epopeja_karta, without
  which focus mode kills it within ~1s at home. Not deployed to the device
  yet, so config and phone are out of sync until deploy.sh runs.
- apps.py: correct the epopeja_karta comment. It claimed there was no
  desktop target; a linux/ target was since added so the app can be driven
  on the desktop during development. linux stays False - the app ships no
  desktop entry and gets no hicolor set.
- The evidence and contract artifacts the pre-commit hooks require.

Verified: 44 app_icons tests pass, 100% branch coverage on the package,
safe_box_overflow for quill-nib is (0, 0), and the generated mipmaps show
the nib rather than the stock Flutter icon.

c600760e71 Move billsplit Flutter app into the monorepo
billsplit was a standalone Flutter app in ~/Downloads with one commit and no
git remote — that directory was the only copy of its history.

Three things the move needed beyond copying the tree:

- The root .gitignore silently swallowed 32 of its files (*.png, *.ico,
  *.manifest). Ignored files do not error on `git add`, they just vanish, so
  this would have committed an app that cannot build. Added a trailing block
  of ! overrides plus .binary-allowlist (which did not exist yet) — the
  documented in-repo exception for binaries a build genuinely needs. The
  ../testsAndMisc_binaries/ symlink scheme does not apply: those directories
  are gone, and a symlinked PNG breaks a fresh clone.

- billsplit/.github/workflows/ci.yaml was inert once nested; GitHub only reads
  workflows at the repository root. Relocated with a working-directory and a
  billsplit/** path filter.

- The app's coverage gate moved to python_pkg/billsplit_coverage/ so every
  Python file stays under python_pkg/, and gained a test suite at 100% branch
  coverage as that location requires. billsplit/ now holds only Dart.

Also replaces the stock Flutter icon with a family icon from the shared
generator. The glyph is a filled silhouette because the family's 72px stroke
cannot carry a fine torn edge, and the split is an evenodd-cut perforation so
the holes stay transparent on the foreground and monochrome layers.

2b3c1a69f7 fix(hooks): make git hooks and their toolchain mandatory and fail-closed
A completely absent `prettier` binary went unnoticed long enough for
unformatted markdown to reach main. Two independent causes, both fixed here.

No pre-push hook existed. The three hooks declaring `stages: [pre-push]` in
.pre-commit-config.yaml — prettier, ci-mirror, pytest-coverage — therefore
never ran locally at all. Adds one.

The pre-commit hook failed open. shfmt and shellcheck were wrapped in
`if command -v`, and the entire pre-commit framework was skipped with a
warning when its binary was missing. A silently skipped gate is
indistinguishable from a passing one, so a missing tool now aborts.

- lib/common.sh: require_tool tries `sudo -n pacman -S` and aborts with the
  exact command when a tool cannot be installed non-interactively;
  verify_toolchain applies it to all eight binaries the hooks invoke.
- The pre-push hook resolves git's stdin refs into --from-ref/--to-ref.
  Without a range, `pre-commit run --hook-stage pre-push` checks *staged*
  files, and nothing is staged at push time, so prettier would have received
  zero files and passed vacuously.
- ensure_hooks_path repairs core.hooksPath drift on every hook run.
- meta/scripts/install_hooks.sh covers the one case the hooks cannot
  self-heal — a fresh clone where the config was never set, so nothing runs.
  `--check` reports state and exits non-zero when incomplete.

Note `pre-commit install` must never be used here: it writes into
.git/hooks/, which git ignores entirely while core.hooksPath is set.

a47191673a feat(reverse_survivors): migrate Reverse Survivors game into the monorepo
Moves the standalone React 19 + Vite 8 + TypeScript 6 game from
~/Downloads/reverse/reverse-survivors into reverse_survivors/, so it is
version-controlled, indexed, and covered by CI instead of sitting untracked
outside any repository.

- Relocates the project's nested .github/workflows/ci.yml to the repository
  root as .github/workflows/reverse-survivors-ci.yml. GitHub only reads
  workflows from the root, so the nested copy would have been inert — same
  treatment billsplit received. The workflow is path-scoped to
  reverse_survivors/** and runs npm ci / check / build on Node 22.
- Sets cache-dependency-path on actions/setup-node, since
  defaults.run.working-directory applies only to run: steps and not to
  actions; without it the npm cache looks for a lockfile at the root.
- Keeps npm and the existing package-lock.json. TypeScript stays pinned at
  6.0.3 deliberately: typescript-eslint 8.65 caps its peer range at <6.1.0
  and TS 7 drops the JS compiler API that typed linting needs.
- Adds a reverse_survivors/ row to the Repository Layout table in README.md
  and CLAUDE.md.

Verified in place: npm ci, npm run check (95 tests, 100% statements /
branches / functions / lines), npm run build, and a dev-server smoke check
serving /src/main.tsx.

89ed9bc95d wsg_grabber: scrape /wsg/, download every new video, triage with keep/pass
Some checks failed
Pre-commit checks / pre-commit (push) Has been cancelled
Python tests / test (push) Has been cancelled
Shell tests / shell-tests (push) Has been cancelled
Shell tests / arch-tests (push) Has been cancelled
New package. Walks every thread on 4chan's /wsg/, downloads each video it has
not seen, and reviews them one at a time: mpv embedded in a Tk window via --wid
with Keep/Pass/Undo directly beneath the picture.

Dedupe is structural rather than a convention. Every post carrying a file also
carries md5 -- base64 MD5 of the whole file -- so it is the sqlite primary key.
An already-seen video costs zero bytes to skip and a byte-identical repost in
another thread collapses onto the existing row. Verified against a live file:
the API's Nz9OEKdMuMZEdYE6eLTKmA== matched base64(md5(bytes)) exactly.

Undo is unbounded and survives quitting: the verdict trail lives in the index,
not in memory, so yesterday's decisions can still be taken back.

No downloaded video is ever deleted. A pass moves the file to trash/ and leaves
it there; files.apply_move refuses to overwrite an existing destination, so the
guarantee holds by construction rather than per caller.

Three bugs only running it could find, each caught from evidence rather than
guesswork:
  - the video stayed black: a <Configure> handler set mpv's geometry, fighting
    the automatic sizing --wid already does
  - playback never advanced: refresh() ran every tick and re-sent loadfile ~7x
    a second, restarting the video continuously
  - it froze on one video around the 26th while filenames kept advancing: mpv
    pushes an event stream down the same socket and nothing drained it, so the
    buffer filled and mpv stopped reading commands. Isolated to command #35
    without a drain thread; all 60 honoured with one.

A five-lens review then found nine more, all reproduced before fixing: a failed
mpv start stranded the non-daemon worker forever; undo could clobber a file in
incoming/; a NUL-bearing md5 poisoned the index permanently; an oversized int
killed the worker with no event; gzip bombs on both hosts were accepted; the
board endpoints were fetched unconditionally forever; and Session.missing could
corrupt the undo trail.

mpv runs as a subprocess over its JSON IPC socket rather than via python-mpv,
which resolves libmpv at import time and would fail on CI while passing here.
Third-party surface is requests alone, already declared.

277 package tests, 100% branch coverage on all 22 modules, no suppressions.

9ab005f18f Point the hook test at the extracted session_autopsy, add the artifacts
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
The gate caught this: test_session_autopsy_hooks reads the DEPLOYED hook under
~/.claude, so repointing that hook to kuhyx/mcp-servers broke an assertion still
expecting `python_pkg.session_autopsy`. Exactly what a deployment-path test is
for — a test against a stale in-repo copy would have stayed green.

The replacement is stronger than what it replaces: it asserts both the new module
path AND that "python_pkg" is absent, so regressing to the old location fails
rather than passing quietly. The mutation checker confirms all 12 tests are still
killed by at least one mutation.

Also adds the evidence/contract artifacts for the extraction. They were written
for 627b9e7 but never committed: that commit was pure deletions, and the
ai-evidence-contract hook does not treat deletions as code changes, so it passed
without them.

9d7751cebb kcd2 dice solver: serve it at dice.kuhy.duckdns.org, fit all 43 dice, move inventories between devices
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
The solver only ran behind ./run.sh, had one media query in the whole
stylesheet, and kept the inventory in a 46vh scroll box that showed maybe a
third of the 43 dice. Setting it up on the PC did nothing for the phone.

Deployment
  dice.kuhy.duckdns.org, behind the existing gitea-caddy edge. DuckDNS already
  wildcards *.kuhy.duckdns.org (checked against 1.1.1.1 and 8.8.8.8), so no
  dashboard step. deploy_build.sh builds to dist.staging and rsyncs into dist/
  with --delete-after --delay-updates; plain --delete removes stale assets
  before writing the new ones, which 404s a client mid-load. A post-commit hook
  starts a MemorySwapMax=0 systemd user unit, so a rebuild can neither slow a
  commit nor thrash zram.

  Three traps found by driving the live URL in a browser rather than curling it:
  a site address of "127.0.0.1:8089" reads as a HOSTNAME, so Caddy enabled
  auto-HTTPS and started an HTTP->HTTPS redirect listener that bound *:80 next
  to the edge -- SO_REUSEPORT would then split inbound HTTP and intermittently
  break ACME for every domain here. The same address also made a Host matcher,
  so the edge's forwarded Host matched nothing and served an empty 200 while the
  local health check passed. And watching dist/'s own inode could never detect a
  detached bind mount: rsync into an existing directory never changes it. Each
  now has a guard that asserts positively rather than failing open.

Dice list
  All 43 on screen at every width, no inner scrollbar. Column count and size
  tier are chosen together from a container query on the panel -- not the
  viewport, which mispredicts by 2x at the point the columns split. Two
  invariants govern it: the list fits above the fold, and the name column stays
  wide enough to tell Painter's die B, G and R apart. The left column holds the
  grid alone, so it is sized to fill the height it owns: one --die-row value
  drives the type, buttons and bar strip, giving a 52px row and 44px buttons on
  a 1296px-tall screen and 20px rows on a phone.

  Three safe-design rules are broken inside .die-list deliberately: sub-16px
  body text, square icon buttons, sub-8px intra-cell gaps. 43 items with a name,
  a chart and a counter in one viewport is arithmetically incompatible with 16px.

Import / export
  A file, the clipboard, or a link carrying the inventory in the URL fragment.
  One validator behind all four entry points including localStorage; it keeps
  what it can and reports what it dropped, so a die added in a later game patch
  costs you that entry, not the inventory. A link never silently overwrites what
  is saved here -- it offers Keep or Discard, and only a link that actually
  carries dice is applied at all, because one encoding a count of zero parsed
  cleanly, blanked the screen, disabled Clear and left Keep writing the emptiness
  over the visitor's own loadout.

session_autopsy
  parse.py (551) and report.py (504) were over the repo's 500-line limit, so
  test_file_length has been failing on main since 5ffd035. Extracted TurnTracker
  and the two candidate-cell helpers. Report output is byte-identical on real
  data apart from its timestamp, checked against HEAD in a worktree.

Verified: 288 TS tests and 911 Python tests, 100% coverage both, lint and
pre-commit clean, 8 viewports measured on the live HTTPS site, solver confirmed
through the real module worker.

5ffd035c21 session-autopsy: measure turn efficiency, the dominant token cost
Cache read is charged per API round-trip on the whole conversation so far, so a
long session's cost is driven by TURN COUNT, not message length. One measured
session spent 267M cache-read against 856k output — a ratio of 290:1. The report
priced tokens but never counted the turns spending them.

Across the 263 stored transcripts this now shows 33,508 tool turns at an 8%
batching rate, of which 4,437 (13%) decided nothing: polling a counter, running
a linter, checking whether a push landed. At 606k average context re-read per
turn that is ~2.7B cache-read tokens on turns a script could have taken.

- turns.py classifies a command as poll / lint_test / vcs_check / substantive,
  deliberately conservative: state-changing commands (git commit, push) count as
  substantive even though they are scriptable, so the reported waste is a floor.
  A turn is only mechanical when EVERY command in it is.
- Batching is grouped by requestId, not by transcript line: one API response can
  span several lines, and counting per line reports every turn as single-tool
  (0% batching where the real rate is 12%).
- records.py gains TurnEfficiency (schema v3, additive — old records read as
  zeros) with derived rates written into to_dict so readers need not recompute.
- report.py gains a "Turn efficiency" section pricing each mechanical kind.
- _TurnTracker owns both the totals and the open turn, after pylint flagged
  _Accumulator over its attribute budget; _Accumulator.turns is now a property,
  so every existing caller is unchanged.

a83b5abc27 python_pkg: track session_autopsy, finishing its interrupted refactor
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
The transcript analyzer behind /compile-candidate lived only in the working
tree. Untracked meant unlinted — pre-commit only inspects files handed to it —
so nothing had ever checked it, and it had been abandoned mid-refactor with
every parse raising AttributeError: '_Accumulator' object has no attribute
'first_timestamp'.

The accumulator had been moved onto the grouped records dataclasses, but three
increment sites and parse_session still read flat attributes that no longer
existed. parse_session now hands over acc.meta and acc.counts directly; only
subagent_count comes from elsewhere, since no transcript line carries it.

Two modules broke the 500-line limit, so they were split along seams that were
already there. signatures.py takes the text-signature helpers — traces.py was
importing them from parse.py, making parse an accidental hub, and now neither
imports the other. stats.py takes the pure number and time helpers. parse.py
521 -> 458, detectors.py 559 -> 467.

The structural lint findings were refactored, not configured away.
_counter_candidates took eight arguments; the five naming which counter field to
mine and at what thresholds became a frozen _CounterSpec, so both call sites are
one line. _extract_skill carried in_span and a line budget as loop variables
across thirteen branches; a _SpanBuffer owns that state now, leaving the walk at
four. record() took twelve flat kwargs and now takes one override per record
block, with session_meta() so a partial meta override keeps the standard
timestamp — a bare SessionMeta(slug=...) would have nulled started_at and
quietly changed the per-week arithmetic. All 36 call sites rewritten by an AST
pass. tests/factories.py moved into conftest.py, where every other package here
keeps shared builders and where name-tests-test does not object.

965 tests pass at 100% statement and branch coverage, every hook is green, and
no suppression was added anywhere. `candidates` and `traces skill-finish` both
run against the real corpus.

4aae92ae09 kcd2_dice_solver: Balatro's die has one joker face, not six
The wiki's dice-effect row for Balatro's die is `{{Dice effect|d|d|d|d|d|d}}`
— six *unfilled placeholder* cells that render as "d%". A previous pass read
those six `d`s as six wildcard faces, which made the die resolve every throw in
the player's favour: EV 8000, bust 0%, and the solver forced it into every
loadout it could. Only one face is the joker (Jimbo's grinning face, visible on
the item icon), and no source publishes the die's side weights at all.

The two joker faces also do not score alike, and the scorer was treating them as
one thing. Per the wiki, a Devil's head "matches any combination but never
scores on its own", while Balatro's joker counts as a 1 when picked alone. So
there are now two substitute slots: a Devil's head is spent inside the
combination it completes rather than resolved to a plain face, which is what
stops it being held as a lone 1. Hands with no substitute keep the original
single-pass code path.

Balatro's die: EV 8000 -> 771.2, bust 0% -> 3.09%; a lone devil's head scores
100 -> 0 and is no longer a legal hold. The two dice now tie exactly on a single
throw of six and differ only mid-turn (813.7 vs 808.3 points per turn), which is
where "may be held alone" actually pays.

Which pip the joker replaces is unpublished; the 1 is assumed, matching the
Devil's head die the game compares it to, and marked UNVERIFIED in the data.

896d7b1d15 Run Arch-only shell tests in a container; harden worktree stubbing
Adds an arch-tests job on archlinux:base-devel so the pacman wrapper,
makepkg wrapper and hosts-guard tests finally run somewhere. They need
an Arch userland and root, which a disposable container provides.

Four more tests still referenced pre-reorganisation paths and could
never find their targets; repairing them took the container set from
two passing to five. All five were verified with --network=none, so
the job installs nothing beyond git (base-devel ships no git, and
actions/checkout needs it).

Also removes the silent-failure mode behind the earlier
music_parallelism confusion. The test now derives its temp-worktree
path from the script's real position instead of hardcoding the depth,
checks up front that ../../lib/common.sh resolves to the stub, and has
the stub write a marker asserted after every run. Previously a
reorganisation made the script source the real
/usr/local/lib/common.sh, so the test measured the live system and
failed as though the daemon were broken.

Three tests stay out, each for a different reason, documented in the
workflow: test_i3blocks_efficiency.sh needs strace and could not be
verified locally (containers here have no DNS);
test_hosts_guard_pacman_integration.sh fails a real assertion worth
investigating; test_security_hardening.sh asserts live host state and
can never pass in a fresh container.

27f44cad4b Add shared launcher-icon generator for the Flutter apps
Every Flutter app still shipped the stock Flutter "beach" launcher icon, and
none had an adaptive-icon descriptor at all. Rather than hand-drawing five
one-off icons, define the family once and let each app contribute only an
accent colour and a glyph.

The family: a charcoal #1B1D21 field carrying one glyph in that app's own
theme seed colour, at a single stroke weight. Glyphs are optically centred
automatically - render.centre_offset rasterises a glyph alone, measures its
ink box, and translates (never scales) the fragment, so a row of icons lines
up while every icon keeps the exact family stroke weight.

safe_box_overflow warns when a glyph exceeds the 560px adaptive-icon safe
box; it caught three real overflows that a launcher mask would have clipped.

6342eaf0e2 feat(byox_ladder): add build-your-own-x difficulty ladder generator
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Ranks the codecrafters build-your-own-x projects by difficulty and emits two
offline, self-contained HTML pages: a per-guide ladder (~360 tutorials) and a
per-category ladder (30 categories), grouped into Beginner/Intermediate/Advanced/
Expert tiers plus an Unsorted bucket. A guide inherits its category's tier;
language only nudges order within a tier. Includes a Makefile pipeline
(fetch -> parse -> build) and 100%-branch-covered tests. Excludes the generated
guide page from codespell since it inlines upstream titles verbatim.

e0f62d699a fix(wellbeing): split focus_mode_daemon to satisfy the 500-line limit
focus_mode_daemon.py has been 509 lines since 22e22c1, over the repo's
cap. It went unnoticed because the Python tests workflow only triggers on
python_pkg/** changes, so that commit never ran CI; the next commit to
touch python_pkg/ exposed it and turned main red.

Extract configuration, logging, notification, /proc process inspection and
the killers into _focus_mode_lib.py, leaving the daemon its policy: the
whitelist, the FocusMode state machine, and main(). log/notify move with
the process code that calls them, so the dependency runs one way and there
is no cycle. The helper is underscore-prefixed and registered in pylint's
init-hook path, mirroring the existing usage_report.py / _usage_report_*.py
sibling-import precedent.

The daemon runs from a symlink in /usr/local/bin, so a sibling import only
works if Python resolves that symlink before setting sys.path[0]; verified
that it does, and the installer symlinks rather than copies, so the sibling
travels with it. Confirmed against the running service: restarts clean and
resumes enforcing, process detection unchanged, status output matches the
pre-split version.

Structural only; no behaviour change.

69242e4bb3 fix(brother-printer): split oversized files, fix order-dependent entry test
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
a12e696 turned CI red two ways, both missed locally because the suite was
run for the brother_printer package alone while CI runs everything in a
random order.

The repo caps Python files at 500 lines and cups_service.py had reached
659. Rather than cut it arbitrarily, extract consumable life tracking -
page counters, replacement baselines, the scale migration, dropped-page
detection - into consumables.py. The seam is real: none of it depends on
CUPS service control, and cups_service needs only estimate_consumable_life
for its fallback query, so the dependency runs one way. The test files are
split along the same seams.

test_main_entry passed or failed depending on execution order: runpy warns
when the target module is already in sys.modules, a sibling test imports
it, and pytest is configured with filterwarnings=error. Drop the module
before running it so the test no longer depends on who ran first.

Structural only; no behaviour change. 692 tests, 100% branch coverage.

a12e696494 fix(brother-printer): report the truth, not invented status codes
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
./run.sh failed outright with ModuleNotFoundError, and once running it
reported a sleeping printer as a critical paper jam. Both are fixed, plus
the defects found while verifying them against the real HL-1110.

Entry point: run.sh ran the script by path, so the absolute
python_pkg.* imports could not resolve. Resolve the repo root and pass
PYTHONPATH as a sudo argument, since sudo's env_reset strips an exported
one. __main__.py had the wrong import prefix and ran main() on import.

Status codes: the table claimed provenance from a "Brother PJL Technical
Reference" that does not appear to exist, and 23 of its 25 entries were
wrong. Rebuilt from the HP PJL Technical Reference Manual, Appendix D,
and verified against six states induced on real hardware (10001 READY,
10003 WARMING UP, 10023 PRINTING, 40000 SLEEP, 40021 TOP COVER OPEN,
41213 NO PAPER) - all six matched the reference, none matched the table.
40000 is SLEEP MODE, which the reference explicitly flags "not an error";
the real jam code 40022 was absent entirely. The inverse also bit: 10006
is TONER LOW, previously shown as a benign "Processing". Codes in no
reference are dropped and now report "Unknown status - check printer
display" rather than a confident wrong answer, and states we infer
ourselves no longer borrow PJL numbers to describe themselves.

Page counts: estimates came from the CUPS page log, which only sees jobs
CUPS logged and counts pages the printer never printed (it logged
total=50 for a job that printed 3). Take them from @PJL INFO PAGECOUNT
instead, migrating stored baselines onto the printer's scale once so the
reported percentages do not jump.

Reading status must not cost anything: a blocking open() hung forever
whenever the printer was unwell - precisely when a status report is
wanted - and the port-status probe stopped CUPS and reset the USB device,
destroying the in-flight job and then misreporting the damage as a
printer error. The fd is now non-blocking with deadline-bounded writes,
and the probe reads the same byte via the free usblp ioctl, skips
entirely while a job prints, and re-attaches the kernel driver.

Dropped pages: the HL-1110 silently discards pages whose 600dpi raster
exceeds its ~1MB memory, stays READY, and CUPS still calls the job
successful - so nothing anywhere reports the failure. Compare CUPS's
claim against the printer's counter between jobs and name the workaround
(lp -o Resolution=300dpi).

402 tests, 100% branch coverage.

2a304691cb fix(pacman): wrap makepkg so an orphaned db.lck can't hang makepkg -i
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Vendored makepkg's run_pacman() waits on /var/lib/pacman/db.lck existence
with no timeout BEFORE invoking pacman, so an orphaned lock hangs
`makepkg -i` forever ("Pacman is currently in use, please wait...") and
the pacman wrapper's stale-lock cleanup never gets a turn. Wrap makepkg
(mirroring the pacman-wrapper pattern) to clear an orphaned lock up front.

- Extract stale-lock logic into shared pacman_lock_lib.sh; pacman_wrapper
  sources it after integrity verification and it is in the SHA256 manifest
- makepkg_wrapper: pre-flight clear for -i/--install; bypass on FAKEROOTKEY
  and non-install; FAIL OPEN if the lib is missing (never brick makepkg)
- Cross-user pacman_process_running() pgrep guard: unprivileged makepkg can
  detect a root pacman its own fuser cannot see (avoids removing a live lock)
- Upgrade survival: rewrap hook (Install/Upgrade only) + check_makepkg_wrapper
  drift verifier + both wrappers wired into the hourly periodic driver
- Fix reorg path bugs: stale ~/linux-configuration periodic path,
  $CONFIG_DIR/hosts -> scripts/periodic_background/hosts, test WRAPPER_DIR;
  refresh .orig only when target isn't already our symlink (no exec loop)
- Tests: test_makepkg_wrapper.sh (18) incl. hook Operation validity; add
  lib-integrity coverage to test_pacman_wrapper_security.sh (also path-fixed)

ef892eb162 phone_focus_mode: block hotspot/tethering to close the second-phone bypass
The focus system only ever filtered this phone's own traffic: /system/etc/hosts
via the system resolver, dns_enforcer and the curfew net layer via OUTPUT. A
tethered second phone's packets are FORWARDed + NAT'd through us on a path none
of that covers, so a second phone on the hotspot browses freely on our mobile
data and defeats focus mode.

Add tether_enforcer.sh: an always-on daemon that acts while focus mode is ON
(at home) or a force-test file is present, converging three levers each tick:
  1. disable Android tether offload (settings global tether_offload_disabled=1,
     snapshot/restore) so forwarded traffic goes through netfilter;
  2. blanket REJECT of the FORWARD chain (iptables + ip6tables, FOCUS_TETHER_BLOCK
     pinned at position 1), rebuilt only when tampered via a chain_intact gate so
     it does not fork an `iptables -L` every second (that overheated the phone
     during curfew-net tuning). Covers WiFi, USB and BT tethering;
  3. best-effort `cmd wifi stop-softap` (Android 11+) so the hotspot visibly
     flips off.
Reverts offload + tears down FORWARD on transition away from home / on SIGTERM.

Wiring: config.sh flags, focus_ctl.sh (tether-status/start/stop/log/test-on/off),
magisk_service.sh boot autostart, deploy.sh push/cp/restart. README section and
a working subprocess regression test (lib/tests/test_tether_enforcer.sh, 17/17).

Verified on-device (BL9000, Android 13): our REJECT jump sits ABOVE Android's
tetherctrl_FORWARD chain, tether_offload_disabled=1 took effect, and
`cmd wifi stop-softap` reports "Soft AP stopped successfully".
