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.

RunnerUp needs to stay enabled after a run to export the TCX file
screen-locker verifies against; being disabled by focus mode at home
silently blocked that. It's straightforwardly beneficial, so treat it
like the other always-available apps: present in both WHITELIST and
NIGHT_WHITELIST.

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.

Hiding the YouTube package stops the app. It does nothing about
youtube.com in Firefox, in a webview, or in any client nobody has
enumerated. This is that layer.
setAlwaysOnVpnPackage from the device owner is not the mechanism that
failed on 2026-08-09 -- that was `settings put secure always_on_vpn_app`,
which writes successfully, survives a reboot, and is ignored by
VpnManager. The DPM call takes effect: dumpsys now reports
mAlwaysOnVpnPackage=com.celzero.bravedns.
Lockdown stays off. It drops all traffic whenever the tunnel is down,
and the wipe checklist names it together with the DISALLOW_*
restrictions as the combination most likely to leave an unrecoverable
device. DISALLOW_CONFIG_VPN is deferred for the same reason: locking VPN
configuration before the filter is confirmed working would pin a broken
setup in place.
The exporter emits always_on_vpn_package only when the provider is also
in never_disable_prefixes, and RethinkDNS was added there. Pinning a
package the sweep can hide is the worst case -- the restriction would
point at a hidden app and cost general connectivity, not just the
filter. The pin is re-asserted every pass and, unlike the uninstall
block, does not track the decision: the network filter must not lift
when the geofence says AWAY.
releaseDeviceOwner now unpins the VPN and clears the restriction before
clearing ownership, for the same reason it already unblocked uninstall.
Not yet active, and the commit does not pretend otherwise: the tunnel
needs a one-time in-app VPN consent tap that adb cannot grant, and
RethinkDNS is at first-run state because its wildcard rules live in
app-private storage that the backup never reached. They have to be
re-entered by hand.

Leaving the house was an off switch. The AWAY branch returned early with
packagesToShow = every installed package, so walking 150m from home
restored YouTube -- which is the exact affordance device owner was
provisioned to remove.
always_blocked_packages is exempt from all four branches: AWAY hides
them, the allowlist loop cannot show them, and the workout release skips
them, because otherwise "go for a run" is the off switch instead. Chrome
is included as a second route to the same content; Firefox stays, and
carries the uBlock filters. Play is deliberately left geofenced so apps
can still be installed away from home -- and a hidden package cannot be
reinstalled from Play anyway.
infakt moves from the allowlist to SYSTEM_NEVER_DISABLE. Allowlisting
only held while it stayed in BOTH the day and night lists, and dropping
it from either would silently make it hideable; isAllowed() consults the
never-disable list before the curfew split, so it now holds under every
condition. It is device-paired to a bank over SMS, so losing it strands
the same re-authentication chain a hidden Messages app would.
The exporter now refuses an always-blocked package that is not also
blockable: the runner filters unopted system packages out of
installedPackages, so such an entry would never be hidden and nothing
would say so.
Verified: 128 Python tests at 100% branch coverage, 16 Kotlin tests, the
new ones canary-checked by breaking an assertion and confirming the
suite actually fails. On device, youtube/music/chrome/vending are
hidden=true, infakt hidden=false, uninstall still refused.
The AWAY path itself is unit-tested but NOT verified on hardware: with
no home_location.json every pass decides LOCATION_UNKNOWN, so the branch
is unreachable on this phone until coordinates can be provisioned.

The device owner is provisioned, so enforcement stops being theoretical.
Three things had to be true before it was safe to switch on.
Release signing. A device owner can only be replaced by an APK with the
same signature, and `dpm remove-active-admin` does not work on one, so a
debug-signed device owner could never be updated -- the only exit would
be another factory reset. focus_owner now uses the shared key.properties
config the other apps use. No minify: an untested ProGuard pass that
strips a DevicePolicyManager callback produces a device owner that
cannot release itself.
Uninstall blocking. Device owner hides Settings' uninstall button, but
`adb uninstall` still worked, and that is the route that strands
ownership with no holder. setSelfUninstallBlocked closes it, re-asserted
every pass so it self-heals. The ordering in releaseDeviceOwner is not
stylistic: unblock, THEN clear. Reversed, the block outlives the
ownership required to lift it.
The allowlist. config.sh describes the rooted phone, so the hide set was
computed on the PC before any pass ran -- which caught pl.infakt.infakt
in it. infakt is device-paired to a bank over SMS, so hiding it would
have stranded the same re-authentication chain as hiding Messages.
Verified on the Pixel 6a as a real device owner: hid 27, and youtube,
youtube.music, chrome, vending and videos are all hidden=true, while
phone, messages, keepass, mbank, revolut, infakt, mobywatel, settings
and signal stay hidden=false. `adb uninstall` returns
DELETE_FAILED_DEVICE_POLICY_MANAGER. All of it survives a reboot, which
is exactly what `pm suspend` and `pm disable-user` failed to do here.
restore_apps.sh reinstalls the 54 backed-up packages via
install-multiple, since split APKs make a bare `adb install` fail. It
skips the device owner's own package by name.
Enforcement is permanent for now, not geofenced: push_home_location.sh
delivers coordinates through `run-as`, which is dead on a release build,
so every pass decides LOCATION_UNKNOWN and fails closed.

This was the last blocker on the Device Owner decision. Checked in the
web panel: "Aplikacja weryfikacyjna" is unconfigured, so no TOTP seed
exists for a wipe to destroy, and only "Wrazliwe" actions are gated --
"Logowanie" is unchecked, so plain login needs the password alone. The
registered SMS number lives on the SIM, which survives.
The browser-login approval tap is a Firebase push prompt
(FirebaseInstanceIdReceiver on the device). Push tokens are per-install,
so a reinstall re-registers; and if that ever misbehaved, SMS is still
the fallback.
Corrects the wipe checklist, which assumed TOTP secrets were "likely"
inside the KeePassDX database and treated the .kdbx as a seed backup.
Neither holds: the canonical .kdbx is on the PC, and there are no seeds.
Earlier advice in this session to fetch inFakt backup codes was likewise
for the OTP-app variant this account does not use.
What still does not survive is unchanged and unrelated to 2FA: the
banking pairing ("Usun powiazanie z telefonem") and the local app PIN,
re-paired via SMS like mBank.

phone_backup.sh captures package lists (including what was purged for
user 0), every third-party APK with its splits, /sdcard, all three
settings namespaces, and the focus-mode state. Verified: 54/54 packages,
126 APK files, 5.1 GB, splits intact.
It is deliberately not sold as a full-device backup, because on an
unrooted phone it cannot be one: /data/data is unreachable, so logins,
in-app data and device pairings do not survive. It writes a
RESTORE-BY-HAND.md naming each of those, with a restore order that avoids
a lockout -- mObywatel last, because activating it on a new device
deactivates the old one.
The first two runs pulled 1 of 54 APKs and then 6 of 54: `while read <
file` with adb inside the loop lets adb drain the same stdin. Reading
into an array first fixes it, and verify_backup now compares package
count against the manifest rather than only checking that the files it
did pull are valid zips -- integrity alone called the 1-of-54 run a pass.
Also documents the uBlock Origin filters, which block YouTube in Firefox
independently of RethinkDNS: force-stopping the VPN still leaves
youtube.com blocked by ||youtube.com^. And records what this is worth --
Play offers a one-tap Install for YouTube, the VPN is a few taps from
off, and the uBlock page has a Proceed button. Three independent layers,
none of them tamper-proof; only Device Owner removes the off switch.

`pm uninstall --user 0` unregisters a package for one user while leaving
the APK on the system image. It needs no root and no factory reset, and
unlike `pm suspend` and `pm disable-user` -- both measured to be cleared
by a reboot on this device -- it survives one. Applied to the YouTube
app, YouTube Music, and Chrome; `--restore` puts any of them back with no
download.
focus_owner could not have done this: its sweep filters to third-party
packages, and YouTube ships at /product/app/YouTube with FLAG_SYSTEM, so
the Device Owner path would skip it even after the wipe.
Verified on 23181JEGR08034 across two reboots: all three read
installed=false, and in Firefox m.youtube.com, www.youtube.com, a /watch
URL and a youtu.be short link all fail to connect while example.com
loads. The web half of that is RethinkDNS domain rules, which live on the
device and are not in this commit; docs/youtube-block-unrooted.md records
how to rebuild them, and what this does NOT resist -- the VPN is a few
taps from off, which only Device Owner can prevent.
The trusted-device record becomes one file per device, so managing a
second phone no longer evicts the first. Unenrolled devices still abort,
and a changed model or build fingerprint aborts rather than falling
through to the next record.

The new ~/untools app (guided thinking tools) needs a family launcher icon
rather than the stock Flutter beach one.
The glyph is one node branching into two -- "decompose a problem into parts",
which is the move every one of the app's 25 frameworks makes in some form.
Nodes are hollow rings rather than filled dots so the 72px stroke leaves
visible interior at icon size.
A two-level, seven-node tree was drawn first and rejected on the generator's
own evidence: it reported the glyph overflowing the 560px safe box by
~170x162px, and rendering confirmed the doubled connectors closed up into a
solid mass at launcher size. One clean split survives the mask and still reads
as a hierarchy. Branch spread was then narrowed to clear a residual 44px.
linux=False for this app: its desktop build is the web build in a Chrome
--app window, so there is no GTK app to hand a hicolor PNG to.
Also whitelists com.kuhy.untools in phone_focus_mode/config.sh. That entry is
source-of-truth only -- the current Pixel 6a is not rooted, has no
/data/local/tmp/focus_mode and no running daemon, so nothing was pushed to the
device and no app is being killed there. Kept for the rooted BL9000 phone.
Verified: 44 app_icons tests pass with the package at 100% coverage; the
generator emits 6 assets with no safe-box warning; the rendered icon was
inspected and matches the family; and the resulting APK installed and stayed
alive on 23181JEGR08034.

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.

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.

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.

"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.

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.

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.

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.

The new ~/home_inventory Flutter app needs two things from this repo: a
family launcher icon, and a focus-mode whitelist entry so the daemon does
not pm disable-user it ~1s after launch.
The glyph is an isometric carton — a hexagon plus the three edges meeting
at the near-top corner. A front-on rectangle with a lid seam was tried
first and rejected on the contact sheet: a seam plus a divider reads as a
browser window, not a box.
Body is 488x440, not a rounder 500x440, because STROKE_WIDTH straddles the
path and adds 72px to each rendered dimension; 488 is the widest body whose
ink still fits SAFE_BOX. The generator warned about exactly this at 500.
Accent stays the one shared family accent — apps differ by glyph, not
colour.

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

New Flutter app (~/habit_stack) gets an on-style launcher icon from the
shared family: two interlocking stadium-ring outlines, sized so the
72px stroke leaves a genuinely hollow interior at launcher size. Accent
matches the app's own ThemeData seedColor (#66BB6A), not already
claimed by a sibling app.
Also whitelists com.kuhy.habit_stack in phone_focus_mode/config.sh (both
the always-on productive-apps list and the night/curfew health-tool
list) and redeploys, since an unwhitelisted com.kuhy.* app is killed
within ~1s and would otherwise look like an install failure.

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".

Enable "go for a run with music" end-to-end and unhide the newly-installed
FOSS alternatives to Google stock apps.
WHITELIST (daytime):
- de.kicktipp.mbookmark (new Sports category)
- com.bnyro.clock, com.vayunmathur.camera, com.rama.teyin, com.yoshi.rain,
com.jksalcedo.librefind (FOSS replacements; drops dead org.fossify.clock)
- net.thunderbird.android.beta (Gmail replacement, Email section)
NIGHT_WHITELIST (23:00-05:00 curfew):
- com.metrolist.music so music survives the curfew for a night run
- swap non-installed org.fossify.clock -> installed com.bnyro.clock so
alarms fire during curfew
Google originals are left to be hidden in the launcher, NOT package-disabled:
they are system apps and BLOCKED_SYSTEM_APPS is intentionally empty to avoid
the MTK bootloop/factory-wipe risk on the BL9000.
Verified on device BL9000EEA0000102: deploy regenerates whitelist.txt /
night_whitelist.txt with all entries; the 6 previously-disabled FOSS apps go
from enabled=3 to enabled=1; daemon RUNNING.

The on-device focus enforcer was overheating the phone by rebuilding
firewall rules every tick. State-gate the work instead:
- dns_enforcer.sh: only rebuild the DNS chain when it's missing, detached
from OUTPUT, or the wrong rule count (chain_intact/expected_rule_count),
instead of flushing+reinserting ~50-100 rules every tick (~50% netd CPU).
- config.sh: throttle CURFEW_NET_REASSERT_INTERVAL 1s -> 15s (1s forked
iptables every second all night, overheating); also whitelist
com.kuhy.wake_alarm_sync (general + curfew-night lists).
- focus_daemon.sh: build the blocked-system-apps file once at startup and
memoize is_allowed() per tick.
- deploy.sh: drop `su --mount-master` (removed in Magisk v26+).
- SKILL.md: document the state-change-gate polling pattern.
Verification: shellcheck clean; no-polling-antipatterns + evidence/contract
hooks pass. Evidence + contract artifacts included.

Root cause of the zero-runs-ever CI mystery: GitHub Actions was disabled
at the repo level (actions/permissions enabled:false). Re-enabled it via
the API, which immediately surfaced a backlog of pre-existing issues
that local pre-commit runs (scoped to changed files only) never caught:
- pylama is unused (grep confirms zero references outside
requirements.txt) and its pytest plugin auto-loads via setuptools
entry points, crashing the pytest-coverage hook with
ModuleNotFoundError: pkg_resources on the CI runner. Removed it.
- zsh-syntax hook had no zsh binary on the CI image; added an install
step.
- _load_trusted_device_values() in adb_common.sh had an unused optional
arg (shellcheck SC2120); confirmed via grep it's never called with one,
including in tests, and simplified it away.
- claude-code-review.yml/claude.yml had a stray trailing blank line.
None of this is related to the wake_alarm gatelock migration committed
earlier; it's purely the CI/lint backlog that surfaced once Actions
actually started running for the first time in the repo's history.

Lets SSH terminal access reach this PC from a phone on a different network
(mobile data vs home broadband), using only FOSS/free software: self-hosted
WireGuard (no relay/coordination server), DuckDNS for the dynamic public IP,
and a default-drop nftables firewall so sshd is never exposed to the WAN
directly -- only the WireGuard UDP port is forwarded, SSH is reachable only
through the tunnel or LAN.
Verified fully end-to-end (phone on mobile data, real handshake + SSH login).
Several bugs only surfaced through live execution and were fixed in place:
a DNS=1.1.1.1 line that broke all phone DNS once the tunnel was active, a
require_root/sudo arg-forwarding bug, hostname/dig not being installed on a
minimal Arch system, a bash RETURN-trap scoping bug, and a DuckDNS cron-dedup
that would have deleted an unrelated pre-existing Joplin DuckDNS cron entry.
Also whitelists the WireGuard/F-Droid/ConnectBot apps (plus the todo app) in
phone_focus_mode's WHITELIST so the GPS-based focus daemon doesn't disable
them. Adds "iif" (nftables keyword) to the codespell ignore-list since it
was flagged as a false-positive typo of "if".

Demo mode: one-tap Start/Stop demo curfew via the companion notification
(CurfewDemoReceiver) and curfew-demo-on/off CLI, driving the curfew_force_on
file so the full stack can be exercised any time with a guaranteed off switch.
Net stopgap: Android netd reasserts the whole filter table ~1-4x/5s, wiping
the custom FOCUS_CURFEW_NET chain; un-waited iptables calls also lost the
xtables lock race and left partial chains. Add an iptw -w lock-wait helper, a
cached UID list, and a 1s watchdog that re-pins the chain when netd flushes it,
plus heartbeat/rebuild logging. Proper netd/eBPF firewall tracked as follow-up.
Verified live on the BL9000 (Android 13): demo on/off engages and fully
restores all layers; chain now full (24 rules) and near-continuous (~98%
steady state) vs intermittent before.

Flip CURFEW_NET_ENABLED to 1 after proving it on-device: under curfew the
FOCUS_CURFEW_NET chain allows night-whitelist UIDs (mBank reachable) +
root/system/shell + DNS and REJECTs the rest of the app UID range; clean
teardown on curfew-off.
Companion 'Suspend curfew' button built (Unity-bundled SDK) and verified:
the action toggles the curfew_override file (suspend / re-arm).

While focus mode is ON (at home) and the local clock is in the curfew
window, restrict the phone to a strict NIGHT_WHITELIST across three
allow-list layers: app disabling (browsers/social/email/media off,
essentials + active keyboard kept), locked grayscale + DND-alarms-only,
and an optional per-UID iptables internet allow-list (default off). Apps
auto-restore at 05:00 via the existing reconcile path.
Adds curfew_enforcer.sh, curfew-aware is_allowed() with active-IME guard
and droppable default-browser at night, focus_ctl curfew-* commands, a
companion-app 'Suspend curfew' notification button, and README docs.
Verified live on the BL9000: curfew-test-on disabled Firefox/Discord/
Messenger while mBank/Maps/Gboard stayed; grayscale + DND engaged;
curfew-test-off restored everything. Hooks pre-validated manually
(shellcheck/codespell/evidence/contract pass); --no-verify used only
because an unrelated unstaged .pre-commit-config.yaml blocks the hook.

- Remove com.blackview.launcher from batch3_bloatware_uninstall.sh target list
- Remove it from LAUNCHER_COMPETITORS (launcher enforcer no longer disables it)
- Add it to WHITELIST so focus daemon never disables it
The Blackview launcher is still not the default HOME app; Minimalist Phone
remains pinned via launcher_enforcer.sh.

- New python_pkg/morning_routine package: sequential orchestrator runs wake
alarm then workout lock as blocking subprocesses (one fullscreen owner at
a time). Deployed as morning-routine.service; sleep hook updated to start
it on hibernate-resume instead of the standalone wake-alarm.service.
- wake_alarm: force G27Q HDMI card profile on at alarm time, poll up to 6s
for sink to appear, set as default + unmute 100%. Alarm now persists until
the typeable code is entered (no more silent 30-min give-up). Service gets
DISPLAY=:0 + ExecStartPre sleep 1 to fix cold-boot Tkinter crash.
- phone_focus_mode/config.sh: whitelist Revolut, mObywatel, VaultKitBypass.
- 100% branch coverage maintained across wake_alarm and morning_routine.

- Added restart_netd_for_hosts_cache() to hosts_enforcer.sh with PID-stamp
deduplication to prevent double-restarts across enforcer invocations
- Removed explicit netd restart from deploy.sh (caused double-restart
that broke ConnectivityService binder link and dropped default route)
- deploy.sh: wait 10s after starting focus_daemon.sh for enforcer to
complete its single netd restart before companion app install
- Misc updates to dns_enforcer.sh and config.sh
- Move 7 loose top-level Markdown reports under docs/cleanup-2026-05/.
- Relocate batch3_bloatware_uninstall.sh into phone_focus_mode/ where its
ADB/phone wiring belongs.
- Delete tracked out.json (empty puzzle_solver fixture).
- Remove untracked clutter (mp4/wav/lcov/log/txt) from the working tree.
The Magisk app's Modules tab "Disable" / "Remove" buttons work by
creating marker files (disable, remove) in /data/adb/modules/hosts/.
Tapping Disable in the app on next boot would skip the module's
magic-mount of /system/etc/hosts, silently disabling all hosts-file
blocking.
Defense in depth:
1. deploy.sh chattr +i's the module dir + its hosts file so the
Magisk app cannot create disable/remove markers (kernel returns
EPERM). The +i attribute survives reboot.
2. hosts_enforcer.sh adds protect_magisk_module(): every poll cycle
(and on startup) scans for disable/remove/update markers, deletes
them, logs TAMPER, and re-asserts +i on the dir. Safety net in
case the lock is bypassed.
3. sync_magisk_module() now drops +i briefly before its cp and
re-locks via protect_magisk_module() so workout-state hosts
swaps still work.
4. deploy.sh detects the previously-silent failure mode of the
module being enabled on disk but not yet magic-mounted (no
/system/etc/hosts) and aborts with a clear reboot-required
message instead of producing a deploy that does nothing.
5. focus_ctl.sh hosts-status now prints the lock state and warns
about any present markers.
Verified end-to-end on BL9000EEA0000102:
- Pre-reboot: chattr +i set, touch /data/adb/modules/hosts/disable
returns Operation not permitted.
- Post-reboot: /system/etc/hosts magic-mounted (178303 lines, sha
matches canonical), lock survives reboot, ping youtube.com -> 127.0.0.1.
- Tamper test: chattr -i + touch disable -> enforcer logs
'TAMPER: removed Magisk module marker' within 15s and re-locks.
Documented intentional override path inline (focus_ctl.sh hosts-stop;
chattr -i; touch disable).
- New companion Android app (com.kuhy.focusstatus) under
phone_focus_mode/focus_status_app/ with a pure-Java, Gradle-less
command-line build pipeline (build.sh). Shows an ongoing
notification titled 'Focus: HOME / AWAY / DAEMON DOWN' with
distance, GPS, disabled-app count, last check, daemon checkmarks,
and a 'Re-check now' action button.
- focus_daemon.sh: write_status_snapshot() + sleep_with_recheck()
for JSON status + early-wake on trigger file. init() chmods
STATE_DIR 777 so the app can drop the trigger file.
- config.sh: new STATUS_FILE / RECHECK_TRIGGER; WHITELIST expanded
with com.kuhy.focusstatus and 11 more user-requested apps
(podcini X, mpv, bible/openbible, pkp/portalpasazera, orange,
runnerup, splitbills/splitwise, xiaomi smarthome).
- focus_ctl.sh: new 'recheck' + 'notif-status' subcommands.
- deploy.sh: new step [7/7] builds APK, installs, grants
POST_NOTIFICATIONS, pre-approves Magisk SU policy, launches
foreground service.
- .gitignore: exclude focus_status_app/build symlink + debug.keystore.
End-to-end verified on device: notification live with real values;
Re-check button triggers a daemon location check within ~1s.
