Close the two holes that made the network block advisory 
Both were measured, not theorised. `pm uninstall --user 0
com.celzero.bravedns` succeeded while the VPN was pinned and
DISALLOW_CONFIG_VPN was set -- I ran it to check whether the provider
was protected, and it removed the app, took the DNS filter with it, and
left the always-on pin aimed at a package that no longer existed. The
second hole was quieter: without lockdown, stopping the tunnel let
traffic flow normally, so the filter only held while it was running.

So the provider now gets setUninstallBlocked, re-asserted every pass,
and the pin runs with lockdown. Lockdown is a real hazard and is
deliberate: if the VPN app breaks, the device has no connectivity until
ownership is released. That is only survivable because the release path
lives in the enforcer app and needs no network.

releaseDeviceOwner reads the pinned package before unpinning it, then
unblocks its uninstall. Reversed, getAlwaysOnVpnPackage returns null
after the unpin and the provider would stay unremovable forever -- the
same trap the self-uninstall ordering already avoids.

Home coordinates are provisioned. The pass now logs "applied AT_HOME"
rather than LOCATION_UNKNOWN, so enforcement is finally geofenced rather
than permanent-everywhere, driven by a real fix.

`pm uninstall --user 0` on the provider now returns
DELETE_FAILED_OWNER_BLOCKED.

What this does NOT fix: RethinkDNS's blocklists are gone with the
uninstall, since they live in app-private storage. The filter is running
with no rules and youtube.com resolves normally until they are
re-entered. And nothing here stops those rules being switched off from
inside the app -- no device owner API can.

README.md

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.

Repository Layout

Path Description
python_pkg/ Python packages (each maintained subpackage lives here)
billsplit/ Receipt bill-splitting Flutter app — people, groups, per-item assignment, e-paragon import and xlsx export (Dart, 100 % line coverage gate)
linux_configuration/ Arch Linux setup, i3 config, system maintenance scripts
phone_focus_mode/ GPS-based Android focus enforcer
reverse_survivors/ Reverse Survivors — React/Vite game where you play the horde against an AI survivor (TypeScript, 100 % coverage gate)
scripts/ Workspace-level helper scripts and pre-commit hooks
docs/ Reference docs and historical reports
third_party/ Vendored upstream skills/agents
meta/ 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
