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.

testsAndMisc
A collection of personal projects, scripts, and experiments — from a GPS-based phone focus tool to Linux/Arch automation, with CI, linting, and pre-commit hooks across the board.
Highlights
Phone Focus Mode
Location-based app restriction for rooted Android. Automatically disables non-whitelisted apps within 500 m of home using ADB + Magisk. Features Haversine distance calculation, hysteresis to prevent toggling, fail-safe unlock, and state persistence. Bash, Android ADB.
Linux Configuration
Automated Arch Linux setup: fresh-install scripts, i3 window manager config, LaTeX environment, and system tests. Includes documentation and test result logging.
Scripts
Utility scripts for development workflows — build file validation, secret detection, and custom makepkg helpers.

Repo-wide tooling: pyproject.toml, requirements.txt, .pre-commit-config.yaml, run.sh, lint_python.sh, .fvmrc. Symlinked into the repo root so tools that auto-discover from root keep working. |
Archived / unmaintained projects live in the sibling repository
testsAndMisc-archive.
Tooling
- Python linting: Ruff with all rules enabled (see
meta/pyproject.toml) - Dependencies:
pip install -r meta/requirements.txt(combined runtime + dev) - CI: GitHub Actions — lint, build, and test on push
- Testing: pytest (Python), custom shell-based test harness for scripts
