Extract phone_focus_mode together with focus_policy

github.com/kuhyx/phone-focus-mode

The two halves go as one repo: focus_policy parses phone_focus_mode's
config.sh into the typed policy that focus-owner consumes, and nothing
else references it. 77 commits of history, plus the two Python suites
from linux_configuration/tests/ and the six mutation fixtures from
meta/scripts/fixtures/, all of which named phone_focus_mode paths.

Running the suites -- not reading them -- turned up a real defect the
extraction would otherwise have inherited. config.sh sources the
untracked config_secrets.sh, and ctl_libs_harness.sh never pinned
HOME_LAT/HOME_LON, so the distance assertions were checking against
whatever real coordinates that file happened to hold. The suite passed on
this machine and could not run anywhere else, and a real home location
was load-bearing in a pass/fail condition. The harness now pins a pair
4300 m south of the coordinate its own case seeds, and config.sh sources
the secrets file only when it exists. 136/136 pass with no secrets file
present.

Before making the repo public I scanned the whole history for the known
home coordinates and for any committed config_secrets.sh: zero hits, and
the file was never tracked. The new repo also gained a .gitignore, since
none came across in the filter-repo pass.

test_magisk_service.sh hangs. It hangs identically in the pre-extraction
baseline worktree and appears in no CI list here, so the new repo's CI
skips it with that reason rather than pretending it passes.

check_python_location.sh loses its phone_focus_mode exception now that
the directory is gone; every tracked .py still passes it. The .gitignore
rules for config_secrets.sh and the keystore STAY -- the working copy is
still on this machine and still holds a real location.

Depth 262 -> 248.

-# Phone Focus Mode
-
-Location-based app restriction for a rooted Android phone using wireless ADB.
-
-When within ~500m of home: only whitelisted productive apps remain usable.
-When outside that radius: all apps work normally.
-
-## Requirements
-
-- Rooted phone with **Magisk** installed
-- Wireless ADB enabled (`Settings → Developer options → Wireless debugging`)
-- `adb` installed on your PC (`sudo apt install adb` on Debian/Ubuntu)
-- GPS/Location enabled on the phone
-
-## Setup (first time)
-
-### 1. Find your home coordinates
-
-Open Google Maps, right-click your apartment → copy the coordinates shown.
-
-### 2. Edit `config_secrets.sh`
-
-```sh
-HOME_LAT="-48.876667"   # your latitude
-HOME_LON="-123.393333"  # your longitude
-```
-
-### 3. (Optional) Adjust the whitelist in `config.sh`
-
-To find the exact package name of any app:
-
-```bash
-./deploy.sh <phone_ip> --find-pkg stronglift
-./deploy.sh <phone_ip> --find-pkg anki
-./deploy.sh <phone_ip> --find-pkg pomodoro
-```
-
-Then add the correct package name to `WHITELIST` in `config.sh`.
-
-### 4. Deploy
-
-```bash
-chmod +x deploy.sh
-./deploy.sh 192.168.1.42        # replace with your phone's IP
-```
-
-This:
-
-1. Pushes all scripts to `/data/local/tmp/focus_mode/` on the device
-2. Installs a Magisk `service.d` script so the daemon auto-starts on boot
-3. Starts the daemon immediately
-
-## Usage
-
-```bash
-./deploy.sh <ip> --status    # Current mode, location, distance from home
-./deploy.sh <ip> --log       # View recent daemon log
-./deploy.sh <ip> --list      # List all apps + whitelist status
-./deploy.sh <ip> --enable    # Force focus mode ON (for testing)
-./deploy.sh <ip> --disable   # Force focus mode OFF
-./deploy.sh <ip> --stop      # Stop daemon entirely (restores all apps)
-./deploy.sh <ip> --start     # Start daemon
-./deploy.sh <ip> --restart   # Restart daemon (picks up config changes)
-./deploy.sh <ip> --pull-log  # Download log file to your PC
-```
-
-## How it works
-
-```
-Every 60 seconds:
-  get_location()  ─── dumpsys location ──► lat,lon
-        │
-        ▼
-  calc_distance()  ─── Haversine formula ──► meters
-        │
-        ├── within radius?  ──► enable_focus_mode()
-        │                           pm disable-user all non-whitelisted apps
-        │                           record which apps were disabled
-        │
-        └── outside radius? ──► disable_focus_mode()
-                                    pm enable each app in the disabled list
-```
-
-**Hysteresis:** 50m buffer prevents rapid toggling at the boundary. You must travel
-`radius - 50m` inward to trigger lock, and `radius + 50m` outward to unlock.
-
-**Fail-safe:** If location is unavailable for 5 consecutive checks (~5 minutes),
-focus mode is automatically disabled so you can't be locked out.
-
-**State persistence:** The daemon records exactly which apps _it_ disabled
-(in `/data/local/tmp/focus_mode/disabled_by_focus.txt`), so it never accidentally
-re-enables apps that were already disabled by the user before focus mode ran.
-
-## On-device control (without PC)
-
-From a root terminal app (e.g. Termux + tsu):
-
-```sh
-su --mount-master -c 'sh /data/local/tmp/focus_mode/focus_ctl.sh status'
-su --mount-master -c 'sh /data/local/tmp/focus_mode/focus_ctl.sh disable'
-```
-
-**Why `--mount-master`:** MagiskSU puts each `su -c` session in an isolated
-mount namespace by default, so bind mounts made by the hosts enforcer would be
-invisible (and `/data/adb/focus_mode/*` checks would fail due to SELinux
-interactions). `--mount-master` joins the global namespace where the daemons
-(started from Magisk `service.d` at boot) actually live. The boot autostart
-script doesn't need this flag because `post-fs-data` already runs there.
-
-## File layout
-
-| File                 | Purpose                                                |
-| -------------------- | ------------------------------------------------------ |
-| `config.sh`          | Coordinates, radius, whitelist, constants              |
-| `focus_daemon.sh`    | Main daemon — runs on device, loops every 60s          |
-| `focus_ctl.sh`       | Control utility — runs on device                       |
-| `curfew_enforcer.sh` | Night-curfew enforcer — grayscale + DND + optional net |
-| `hosts_enforcer.sh`  | Bind-mounts `hosts.canonical` over `/system/etc/hosts` |
-| `magisk_service.sh`  | Magisk boot hook → auto-starts both daemons            |
-| `deploy.sh`          | PC-side ADB deployment and control script              |
-
-## Hosts hardening
-
-A second daemon, `hosts_enforcer.sh`, locks the phone's `/system/etc/hosts`
-to the same blocklist installed by `linux_configuration/hosts/install.sh`
-on the PC. Three layers:
-
-1. Canonical copy at `/data/adb/focus_mode/hosts.canonical` is `chattr +i`.
-2. It is bind-mounted read-only over `/system/etc/hosts` at boot.
-3. A watchdog verifies a sha256 every 15 seconds and restores on mismatch.
-
-This blocks the common `echo > /etc/hosts` one-liner from a terminal app.
-It is NOT a guarantee against a determined root user on the device itself —
-a real "impossible without USB" gate would require removing `su` access,
-which would break the rest of this system. The watchdog at least ensures
-tampering is logged and reverted within ~15s.
-
-Status and logs:
-
-```bash
-./deploy.sh <ip> --hosts-status
-./deploy.sh <ip> --hosts-log
-```
-
-## Periodic rescan / Play Store
-
-The focus daemon now **re-scans every tick** (not just on first entry). If
-you re-enable an app via Play Store or `pm enable`, it gets re-disabled
-within `CHECK_INTERVAL_FOCUS` seconds. `com.android.vending` (Play Store),
-`com.*.packageinstaller`, and popular terminal apps are also uninstalled
-`--user 0` in focus mode to close the usual bypass paths. Google Play
-Services (`com.google.android.gms`) is left alone so banking apps work.
-
-## More detail
-
-Split out to stay under the 250-line cap.

-# Night-curfew enforcer for rooted Android.
-#
-# Companion to focus_daemon.sh. The daemon handles the APP layer (disabling
-# everything not in $NIGHT_WHITELIST while the curfew window is open at home).
-# This enforcer adds the three "make the phone boring + unreachable" layers and
-# keeps them locked by re-applying every $CURFEW_ENFORCER_INTERVAL seconds:
-#
-#   1. Grayscale   - force the display monochrome via the accessibility
-#                    daltonizer. The single biggest behavioural deterrent.
-#   2. DND         - force Do-Not-Disturb to alarms-only so notifications stop
-#                    pulling you back in, while the morning alarm still rings.
-#   3. Net curfew  - (default OFF) per-UID iptables allow-list: only the
-#                    $NIGHT_WHITELIST app UIDs (plus root/system/shell + DNS)
-#                    get network; every other app is cut off.
-#
-# "Locked" = snap-back: a manual toggle in Settings is reverted within one
-# interval. True impossibility would require blocking the Settings app, which
-# risks system instability, so we deliberately do not.
-#
-# Acts ONLY while curfew is active (time window or forced) AND, for the
-# non-forced case, while focus mode is ON (i.e. you are at home). On the
-# transition back to day it restores the snapshotted display/DND state and

-# Device Owner and no factory reset, and — unlike `pm suspend` and

-#
-# It is fully reversible: `pm install-existing --user 0 <pkg>` brings

-#
-# This exists because focus_owner cannot do the job. Its sweep filters

-# ============================================================
-# DNS enforcer for rooted Android.
-#
-# Why this exists:
-#   /etc/hosts only works for lookups done by the *system* resolver
-#   using classic DNS (UDP/TCP 53). Two bypass channels defeat it:
-#     1. DNS-over-TLS (DoT, port 853) - used by Android when Private
-#        DNS is "automatic" or set to a specific provider.
-#     2. DNS-over-HTTPS (DoH, port 443) - used by Chrome/Brave's
-#        "Use secure DNS" feature and some apps directly.
-#
-# Strategy:
-#   1. Force `settings global private_dns_mode off` so the OS stops
-#      doing DoT (there is no public DoT-by-hostname toggle).
-#   2. Drop outbound traffic to a fixed list of well-known DoH/DoT
-#      endpoints via iptables / ip6tables so apps' fallback logic
-#      has to use the regular resolver, which consults /etc/hosts.
-#
-# Limitations:
-#   * A custom app that hardcodes an obscure DoH IP is not caught.
-#   * A root user can `iptables -F` or re-enable private DNS - but
-#     this loop re-asserts every $DNS_CHECK_INTERVAL seconds and
-#     leaves tamper logs.

-# Night curfew and the hotspot/tethering block
-
-## Night curfew (after 23:00 at home)
-
-On top of the location-based focus mode, a **time-gated curfew** makes the phone
-boring and largely unusable late at night so you go to sleep instead of doom-
-scrolling. It activates only when focus mode is already ON (i.e. you are at
-home) **and** the local clock is inside the curfew window (default 23:00–05:00).
-Out of that window, or away from home, nothing changes.
-
-While the curfew is active it applies three allow-list layers — _block
-everything except a short essential list_:
-
-1. **Apps.** The daemon swaps the permissive `WHITELIST` for the strict
-   `NIGHT_WHITELIST` (banking, maps, calendar, clock, authenticators, gov ID,
-   workout/diet). Everything else — browsers, social, messaging, email, media,
-   manga, stores — is `pm disable-user`'d and re-enabled automatically at
-   05:00. Same proven mechanism as location focus; no new disable path.
-2. **Display + notifications.** `curfew_enforcer.sh` forces the screen to
-   **grayscale** and DND to **alarms-only**, re-applying every 5s so toggling
-   them off in Settings snaps back. (Snap-back is the realistic lock; truly
-   blocking Settings risks system instability, so it is deliberately avoided.)
-3. **Internet (optional, default OFF).** A per-UID `iptables` allow-list that
-   gives network only to the `NIGHT_WHITELIST` apps (plus root/system/shell +
-   DNS) and cuts off every other app. Enable `CURFEW_NET_ENABLED=1` in
-   `config.sh` only after validating it on-device (see test hook below).
-
-### Configuration (`config.sh`)
-
-```sh
-NIGHT_CURFEW_ENABLED=1       # master switch
-NIGHT_CURFEW_START="2300"    # local HHMM; window wraps past midnight
-NIGHT_CURFEW_END="0500"
-CURFEW_GRAYSCALE_ENABLED=1   # force monochrome
-CURFEW_DND_ENABLED=1         # force DND alarms-only
-CURFEW_NET_ENABLED=0         # per-UID internet allow-list (prove first!)
-```
-
-Edit `NIGHT_WHITELIST` (right below `WHITELIST`) to choose what stays usable at
-night. Allow-list by design: when in doubt, leave it out. The active keyboard
-and the core dialer/SMS/home apps are always protected automatically (a 1am
-reboot can never strand you without a keyboard), and the default browser is
-intentionally _not_ protected at night so it can be disabled.
-
-### Control
-
-```bash
-# On-device (root shell):
-focus_ctl.sh curfew-status     # window, enforcer state, what's applied
-focus_ctl.sh curfew-test-on    # FORCE curfew now (daytime validation)
-focus_ctl.sh curfew-test-off   # clear the force
-focus_ctl.sh curfew-off        # escape hatch: suspend curfew now
-focus_ctl.sh curfew-on         # re-arm (clear the override)
-focus_ctl.sh curfew-log        # enforcer log
-```
-
-### Opting out at 2am (no PC)
-
-The companion status notification grows a **"Suspend curfew till morning"**
-action while the curfew is active. Tapping it drops the override file (curfew
-off until you re-arm); the label flips to **"Re-arm curfew"**. The action is
-hidden during the day so it is not a casual temptation. Without the PC this is
-the only on-device opt-out — by design. From the PC you can always
-`./deploy.sh <ip> --restart` or run `focus_ctl.sh curfew-off` over ADB.
-
-### Validating before you trust it overnight
-
-Because a misconfigured curfew can lock apps at 2am, validate it during the day
-with the force hook, **not** by waiting for 23:00:
-
-```bash
-focus_ctl.sh curfew-test-on    # mBank + keyboard work, Firefox gone, gray, DND
-focus_ctl.sh curfew-test-off   # blocked apps come BACK (the reconcile path)
-```
-
-The clock parser fails **open** (treated as daytime) on a malformed time, so a
-broken `date` can never trap you behind the strict list.
-
-## Hotspot / tethering block (closes the "second phone" bypass)
-
-Every other network layer only filters **this** phone's own traffic:
-`/system/etc/hosts` is consulted by the phone's system resolver, and both
-`dns_enforcer` and the curfew net layer only touch the **OUTPUT** chain. When
-the phone shares its mobile data as a WiFi hotspot, a tethered second phone's
-packets are **FORWARDed + NAT'd** through this phone on a path none of that
-covers — so the second phone browses freely and defeats focus mode.
-
-`tether_enforcer.sh` closes that hole. It is always-on but **only acts while
-focus mode is ON** (i.e. you are at home, `current_mode.txt == focus`), and
-converges three levers every `TETHER_CHECK_INTERVAL` seconds:
-
-1. **Disable tether offload** — sets `settings global tether_offload_disabled 1`
-   so forwarded traffic is actually seen by netfilter instead of being shunted
-   around it by the hardware/BPF fast path. Snapshotted on entry, restored on
-   exit.
-2. **FORWARD blanket REJECT** — an `iptables`/`ip6tables` chain
-   (`FOCUS_TETHER_BLOCK`) pinned at position 1 of `FORWARD`, rejecting all
-   forwarded packets. This is the version-independent catch-all and covers
-   **WiFi, USB and Bluetooth** tethering. The phone's own traffic uses
-   OUTPUT/INPUT, never FORWARD, so normal connectivity is untouched. Rebuilt
-   only when tampered (chain-intact gate), so it does not fork an `iptables -L`
-   every second (that pegged netd and overheated the phone during curfew-net
-   tuning).
-3. **Stop the softAP** (best-effort, WiFi only, Android 11+) — `cmd wifi
-stop-softap` each tick so the hotspot toggle visibly flips back off.
-
-On the transition away from home it restores the offload snapshot and tears the
-FORWARD chain down, leaving tethering usable.
-
-### Configuration (`config.sh`)
-
-```sh
-TETHER_ENFORCER_ENABLED=1     # master switch
-TETHER_CHECK_INTERVAL=5       # re-assert cadence (seconds)
-TETHER_STOP_SOFTAP_ENABLED=1  # also actively kill a running softAP
-```
-
-### Control
-
-```bash
-focus_ctl.sh tether-status     # enforcer state, offload flag, FORWARD chain
-focus_ctl.sh tether-test-on    # FORCE the block now (daytime validation)
-focus_ctl.sh tether-test-off   # clear the force
-focus_ctl.sh tether-stop       # escape hatch: stop it, restore tethering
-focus_ctl.sh tether-start      # (re)start the enforcer
-focus_ctl.sh tether-log        # enforcer log
-```
-
-The escape hatch is `tether-stop` over ADB (or a fresh `deploy.sh`), consistent
-with `dns_enforcer`/`launcher_enforcer` — there is no companion-app button.
-`tether_override` (created manually) suspends the block without stopping the
-daemon.
-
-### Validating before you trust it
-
-Because Android's tether offload can silently skip the FORWARD rule on some
-ROMs, validate on-device with a **real second phone** — do not trust rule
-counts:
-
-```bash
-focus_ctl.sh tether-test-on    # hotspot on + second phone browsing → it loses
-                               # internet within one interval; this phone stays
-                               # online. Watch: focus_ctl.sh tether-log
-focus_ctl.sh tether-test-off   # forwarding restored, second phone browses again
-```
-
-If the second phone keeps browsing with the block applied, offload is being
-bypassed: confirm the exact global key with
-`adb shell su -c 'settings list global | grep -i offload'` and update
-`TETHER_OFFLOAD_KEY` in `config.sh`.

-# Policy list rationale
-
-Prose moved out of `phone_focus_mode/config.sh` to keep that file under
-the repo's 250-line cap. The lists themselves stay in `config.sh` and
-must: `python_pkg/focus_policy/loader.py` finds them by regex-scanning
-that file's text alone, so a list moved elsewhere silently parses as
-empty.
-
-## Allowed Package Prefixes
-
-ALLOWED PACKAGE PREFIXES
-Matched as prefixes on whole labels, exactly like $SYSTEM_NEVER_DISABLE:
-"eu.kanade.tachiyomi" covers "eu.kanade.tachiyomi.sy" and
-"eu.kanade.tachiyomi.extension.all.mangadex", but not
-"eu.kanade.tachiyomisomething".
-This exists because Tachiyomi installs every source as its OWN apk. Listing
-them individually means each newly installed extension is invisible until
-this file is edited and the policy regenerated -- a recurring chore that
-looks exactly like a bug from the phone.
-Weaker than the exact list by construction: a prefix allows packages that do
-not exist yet. Keep the prefixes narrow and vendor-specific for that reason.
-
-## Night Curfew Whitelist
-
-NIGHT CURFEW WHITELIST
-These are the ONLY third-party apps that stay enabled during the curfew
-window (see NIGHT_CURFEW_* above). Everything else in $WHITELIST — browsers,
-social, messaging, email, stores, transit — is disabled.
-Allow-list by design: when in doubt, leave it OUT.
-EXCEPTION: $NIGHT_ALLOWED_PREFIXES is applied on top of this list, and it
-currently carries "eu.kanade.tachiyomi" — so manga IS available during the
-curfew, deliberately (chosen 2026-08-14). This paragraph used to say manga
-was disabled at night; it was true until that change. Do not "restore" it
-without also emptying $NIGHT_ALLOWED_PREFIXES, or the comment and the
-behaviour disagree again.
-Parsed exactly like $WHITELIST (one package per line, '#' comments ignored).
-The sysprotect prefixes ($SYSTEM_NEVER_DISABLE) and the default-handler guard
-(dialer/SMS/home/browser/IME) still apply on TOP of this list, so the active
-keyboard and core system apps are protected even if omitted here.
-
-## System packages that must never be disabled
-
---- System / essential packages that must NEVER be disabled ---
-These are matched as prefixes (startswith).
-You generally don't need to edit this list.
-pl.infakt.infakt is the one non-system entry. Allowlisting it is weaker:
-that depends on it staying in BOTH the day and night lists, and dropping it
-from either would silently make it hideable. It is device-paired to a bank
-over SMS, so losing access to it strands the same re-authentication chain a
-hidden Messages app would. isAllowed() checks this list first, before the
-curfew split, so it holds under every condition.
-
-## Whitelisted apps
-
-WHITELISTED APPS
-These apps will ALWAYS remain enabled, even in focus mode.
-Package names verified against installed packages on 2026-02-22.
-
-## Night curfew
-
-NIGHT CURFEW (time-gated strict allow-list)
-When focus mode is ON (i.e. you are at home) AND the local clock is inside
-the curfew window, the daemon switches from the permissive $WHITELIST to the
-strict $NIGHT_WHITELIST: every app not on that short list is disabled. This
-is the "stop using the phone after 23:00 at home" layer. The companion
-enforcer (curfew_enforcer.sh) adds grayscale + DND + an optional per-UID
-network allow-list on top. Times are local 24h "HHMM"; the window wraps past
-midnight when START > END (e.g. 2300 -> 0500).
-
-## Why dev.kuhy.todo is in the night list
-
-Capture-only notes app. Added 2026-08-14 after a curfew-window deploy
-installed it and the enforcer removed the package ~80ms later: it was in
-the day list but not here, so any build shipped after 23:00 was silently
-uninstalled. This is a deliberate loosening of the answer-the-phone /
-reach-a-bank / handle-an-emergency rule above -- writing an idea down at
-night is the one thing this app does, and losing the deploy path for six
-hours a day cost more than the distraction risk.
-
-## Why the Play Store is in the day list
-
---- App store (day only; deliberately absent from the night list) ---
-NB: never write a dollar-sign variable reference inside this list. WHITELIST
-is a double-quoted string, so even a comment line expands, and deploy.sh
-runs under set -u, where an undefined name aborts the whole deploy. A
-reference to the night list sat here and did exactly that (it is defined
-below this point, so it was still unset), blocking every focus-mode deploy.
-Same rule for double quotes: one in a comment ends the string early.
-infakt cannot be installed or updated without Play, and it is device-paired
-to a bank, so losing the ability to update it strands a re-authentication
-chain. This does NOT reopen YouTube: the sweep is default-deny for
-third-party packages, so anything installed from Play is hidden on the next
-at-home pass, and the always-blocked set (YouTube, Chrome) is never restored
-by the AWAY branch either. Reinstalling YouTube from Play is UNTESTED as a
-bypass:
-the sweep would re-hide it within one pass regardless, but treat the claim
-that Play cannot resurrect a blocked app as unverified until someone tries.
-NOTE: never use a double-quote character anywhere inside these export
-blocks, not even in a comment. The policy loader matches a quoted value up
-to the next quote, so one stray quote terminates the string early and
-silently truncates the allowlist -- which drops apps with no error at all.

-## Updating
-
-After editing `config.sh` (e.g. changing whitelist):
-
-```bash
-./deploy.sh <ip>             # re-pushes all files
-# or just the config:
-adb push config.sh /data/local/tmp/focus_mode/config.sh
-./deploy.sh <ip> --restart
-```
-
-## Troubleshooting
-
-**Location always unavailable:**
-
-- Enable GPS and network location on the phone
-- Open Google Maps once to warm up the GPS provider
-- The daemon logs every attempt; check with `--log`
-
-**App won't disable:**
-
-- Some system apps can't be disabled even as root; they're silently skipped
-- Check log for "Failed to disable" warnings
-
-**Daemon not starting on boot:**
-
-- Verify Magisk is installed and `service.d` is supported
-- Check `/data/adb/service.d/99-focus-mode.sh` exists and is executable
-- Some Magisk versions use `/data/adb/post-fs-data.d/` instead; try both
-
-**Wrong package name in whitelist:**
-
-- Use `./deploy.sh <ip> --find-pkg <keyword>` to find the exact package name
-- Package names are case-sensitive

-| --------------------------- | ----------------------------------------- |
-| `pm suspend`                | No — measured                             |
-| `pm disable-user`           | No — measured                             |
-| `dpm setApplicationHidden`  | Yes — but needs Device Owner, i.e. a wipe |
-| **`pm uninstall --user 0`** | **Yes — measured, twice**                 |
-
-Reversible with `pm install-existing --user 0 <pkg>`: no download, no data
-loss, because the APK never left the device.
-
-## Why focus_owner cannot do this job
-
-`EnforcementRunner.installedThirdPartyPackages()` filters to packages without
-`FLAG_SYSTEM`. YouTube ships at `/product/app/YouTube` **with** `FLAG_SYSTEM`,
-so the Device Owner sweep would skip it — even after the factory reset. The
-apps most worth blocking are preinstalled, which is exactly the set that sweep
-excludes. Worth fixing there separately; it does not block anything today.
-
-## Current state
-
-Removed for user 0, all reboot-verified:
-
-- `com.google.android.youtube`
-- `com.google.android.apps.youtube.music`
-- `com.android.chrome`
-
-Driven by `phone_focus_mode/distraction_purge.sh` (`--list`, `--status`,
-`--restore`). It re-checks each package with `dumpsys` after acting rather
-than trusting the `pm` exit code, and exits non-zero if anything is still
-installed — so a Play Store reinstall surfaces as a failure instead of a
-silent no-op.
-
-## Layer 2: uBlock Origin in Firefox
-
-Independent of the VPN, and that is the point: stopping RethinkDNS does
-**not** restore YouTube in Firefox. Verified by force-stopping
-`com.celzero.bravedns` and loading youtube.com, which produced _"uBlock
-Origin has prevented the following page from loading — `||youtube.com^` —
-found in: My filters"_.
-
-The filters, in uBlock's dashboard → **My filters**:
-
-```
-! YouTube block
-||youtube.com^
-||youtu.be^
-||googlevideo.com^
-||ytimg.com^
-||youtube-nocookie.com^
-||ggpht.com^
-||yt3.ggpht.com^
-||m.youtube.com^
-```
-
-Add them by writing that list to a file, pushing it to
-`/sdcard/Download/`, triggering a media scan (`am broadcast -a
-android.intent.action.MEDIA_SCANNER_SCAN_FILE -d file:///sdcard/...`,
-or the picker will not see it), then using uBlock's **import** button.
-Do NOT type them with `adb shell input text`: it silently strips `|` and
-`^`, leaving bare domains that do not block. Press the checkmark to
-apply, and confirm it greys out.
-
-These live in the Firefox profile, so they are **not** captured by
-`phone_backup.sh` and must be re-added by hand after a wipe.
-
-The block page has a **Proceed** button — one tap. This layer raises the
-cost of bypassing; it does not remove the bypass.
-
-## What is NOT blocked
-
-**Firefox (`org.mozilla.fenix`) is still installed and still reaches
-youtube.com.** It is the only remaining browser after Chrome's removal.
-
-Unlike the three packages above, Firefox is user-installed
-(`/data/app/...`, no `FLAG_SYSTEM`), so `pm uninstall --user 0` would
-**permanently delete it and its data** — no `install-existing` recovery, a
-full reinstall from the Play Store. That asymmetry is why it was left alone
-rather than swept up with the rest. Decide deliberately.
-
-`com.google.android.webview` was checked and left in place: it is the system
-WebView provider, so removing it would break in-app browsers everywhere.
-Chrome and WebView are separate packages on this device, which is why
-removing Chrome is safe.
-
-## The web path, and why DNS is parked
-
-Removing the app kills the recommendation feed, notifications and the
-account-linked session — most of the pull. It does not stop typing
-`youtube.com` into a browser.
-
-Previously rejected approaches, from `focus_owner/docs/`:
-
-- **Home-hosted DoT resolver.** Android's Private DNS fails _closed_, so PC
-  off = phone has no internet at all. Rejected: the phone must work with the
-  PC off.
-- **Hosted DNS (NextDNS, AdGuard, ControlD).** No provider ingests the 185k
-  domain blocklist; free tiers fail _open_ past ~300k queries/month.
-
-The remaining candidate is a **local-VPN content blocker** — an on-device
-`VpnService` that filters without any network dependency, so it works with the
-PC off and does not fail closed on network loss. Not yet scoped; the VPN slot
-was going to be checked when the device disconnected. Note Android allows only
-one active VPN at a time, so this would conflict with any real VPN.
-
-## How strong this actually is
-
-Measured, not assumed:
-
-| Layer            | Undo cost                                                                                                           |
-| ---------------- | ------------------------------------------------------------------------------------------------------------------- |
-| App removal      | **One tap.** Google Play shows a live **Install** button for YouTube (checked on device 2026-08-09; not installed). |
-| RethinkDNS rules | A few taps — the VPN toggle in Settings or the quick-settings tile.                                                 |
-| uBlock filters   | **Proceed** on the block page, or disabling the extension.                                                          |
-
-Nothing here is tamper-resistant, and nothing here can be: on an
-unrooted device without Device Owner, no app can prevent the user
-disabling a VPN or reinstalling from Play. The layers are independent —
-undoing one does not undo the others — so the cost is "three separate
-places" rather than one. That is the honest ceiling.
-
-`DISALLOW_CONFIG_VPN` plus `setAlwaysOnVpnPackage(..., lockdown)` under
-Device Owner is the only tier that removes the off switch, and it needs
-the factory reset in `docs/device-owner-wipe-checklist.md`. See also the
-FLAG_SYSTEM note above: `focus_owner` would need fixing before Device
-Owner could touch YouTube at all.
-
-Also note nothing re-asserts the purge automatically.
-`phone-auto-sync.timer` is inactive and its `ExecStart` points at a path
-that does not exist, so `distraction_purge.sh` is manual today.
-
-## infakt, before any factory reset
-
-Checked 2026-08-09 in the web panel and on the device, because infakt was
-the one app whose loss would have blocked the Device Owner wipe.
-
-- **2FA is SMS-only.** "Aplikacja weryfikacyjna" reads _Skonfiguruj_, i.e.
-  not configured, so **no TOTP seed exists** and a wipe cannot destroy
-  one. The registered number survives on the SIM.
-- **"Logowanie" is unchecked** under _Akcje objęte weryfikacją_ — only
-  _Wrażliwe_ actions prompt. Plain login needs the password alone.
-- The app uses Firebase push (`FirebaseInstanceIdReceiver`) for the
-  browser-login approval tap. Push tokens are per-install, so a reinstall
-  re-registers and prompts arrive at the new install.
-
-So login is safe: reinstall, sign in with the password.
-
-What does **not** survive: the banking pairing (_Usuń powiązanie z
-telefonem_) and the local app PIN. Re-pair via SMS after the wipe.
-
-Do not save anything on that settings page casually — it warns that
-changing it logs out all current mobile sessions.
-
-## Redoing this after a factory reset
-
-The purge is per-user state and does not survive a wipe. Re-run
-`./distraction_purge.sh` after re-enrolling the device.

-# Hosts file enforcer for rooted Android.
-#
-# Mirrors the PC-side guard in linux_configuration/hosts/ but
-# for /system/etc/hosts on Android, which has no chattr, no
-# systemd, and where /system is read-only.
-#
-# Strategy (defense in depth):
-#   1. Canonical hosts file lives at HOSTS_CANONICAL and is
-#      chattr +i (best-effort; ignored if kernel/fs rejects).
-#   2. Bind-mount HOSTS_CANONICAL read-only over HOSTS_TARGET so
-#      that even `echo > /system/etc/hosts` fails for everyone,
-#      including root-in-a-terminal-app, without re-mounting.
-#   3. A watchdog loop re-asserts the bind mount and verifies
-#      sha256 every HOSTS_CHECK_INTERVAL seconds.
-#
-# Known limitation: a user with root *and* willingness to run
-# `umount /system/etc/hosts; mount -o remount,rw /system ...`
-# can still bypass this. Making it "impossible without USB" is
-# not achievable on a rooted phone with a local terminal.
-# This enforcer closes the one-liner gap and adds logging so
-# tampering leaves an audit trail.
