Krzysztof kuhy Rudnicki 19e652dc30 Close three fail-open paths in the prefix trace harness
All three were found by review and reproduced before fixing. Each let a run
report success while proving nothing -- the shape this harness exists to
prevent.

A reused prefix defeated dropped-write detection entirely. Run 1's files were
still there when run 2's manifest was taken, so the manifest reported writes
that never happened and the fixture pair diffed CLEAN. The doc's own examples
demonstrated that workflow. A non-empty prefix is now refused -- not deleted,
since the path is user-supplied -- and the examples use distinct prefixes.

A missing bwrap was swallowed. trace_prefix_bwrap_argv returned 1, but the
caller reads it through `mapfile < <(...)` and a process substitution's status
is discarded, so runner ended up empty and the run continued with no sandbox
and no uid 0. Same swallow as the grep-status one fixed earlier, one layer up.
bwrap is now probed in validate_requirements, before anything runs.

The absolute-path scan only fired when no --bind-abs was given at all, so
binding one path and missing three produced no warning. It now runs whenever
--prefix is given and reports only what is not already covered. Fixing that
surfaced a second defect: --bind-abs on a FILE aborted with "Can't mkdir
/etc/profile: Not a directory", and binding its parent reintroduced the
wholesale /etc shadowing this change had already measured as harmful ($SUDO_USER
collapsing to /home//, the real /etc/profile unreadable). Files are now bound
file-over-file, seeded with a copy so a script that greps before appending sees
real content.

Also measured rather than argued: the XDG redirect. A new fixture run with a
real XDG_DATA_HOME pointing at a decoy shows all four writes landing in the
prefix and the decoy empty -- the rsync --delete data-loss path, proven closed
without running install_leechblock.sh. And no-prefix output was diffed against
cdf2a55 from a detached worktree: byte-identical, so existing baselines hold.

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

focus_owner/ Device Owner app enforcing focus mode on the unrooted Pixel 6a — geofence + night curfew, hides apps the phone cannot un-hide (Dart/Kotlin)
phone_focus_mode/ GPS-based Android focus enforcer (rooted-era scripts; config.sh is still the policy source of truth for focus_owner/)
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

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
