The Device Owner sweep skipped every FLAG_SYSTEM package, which meant it could not touch the apps it exists to block: YouTube ships at /product/app/YouTube as a system app, and so does Chrome. Deleting the filter is not the fix. Measured on the Pixel 6a, that would expose 320 system packages of which 243 match no allowlist entry and no never_disable_prefix -- including com.android.cellbroadcastreceiver (emergency alerts), com.android.credentialmanager and com.android.devicelockcontroller. So system apps stay default-deny and blockable_system_packages is the opt-in. com.android.vending is on the list deliberately: leaving Play reachable makes every other removal a one-tap undo. The list lives in the Python exporter rather than config.sh because it is a safety boundary, and a shell typo should not be able to widen it. The exporter subtracts anything already allowed, so an asset can never state that a package is both allowed and blockable. Kotlin reads the field with a new optionalStringSet: an asset predating the field parses to the empty set instead of throwing, because a throw makes decide() skip the pass and silently disable enforcement. Verified on-device under a profile owner: hid 1 for YouTube, restored 1 when temporarily allowed, and cellbroadcastreceiver, credentialmanager, devicelockcontroller and settings all left hidden=false.

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
