The enforcer failed in both directions: nothing blocked at home, and
everything blocked at the office. The comparison was never inverted --
`metres <= threshold` was always right. Three separate causes:
Only ACCESS_COARSE_LOCATION was declared. Android 12+ fuzzes coarse to a
~1-2 km grid against a 150 m fence, so a fix taken at home routinely landed
outside it, read as AWAY, and restored every app the geofence exists to hide.
FINE is now declared and self-granted by the device owner, along with coarse
and background, re-asserted every pass so a reinstall cannot silently drop it.
There were three states but two behaviours. LOCATION_UNKNOWN applies the
identical sweep to AT_HOME -- correct fail-closed design, indistinguishable
from outside. And nothing ever requested a fix: the pass read whatever another
app happened to cache, so at the office with no navigation running the cache
was empty. Passes now acquire a fix inside a location-typed foreground
service, bounded at 20 s, and treat anything older than 30 min as no fix. That
window is deliberately longer than the 15-minute cadence; a shorter one marks
the newest cache stale on every pass of an idle phone and blocks everything.
None of it was diagnosable. `adb logcat -d -s FocusOwner:V` came back empty
while dumpsys showed 82 alarms had fired, and `run-as` is refused on the
release build device owner requires. So the pass now writes a ring-buffered
JSONL record read back in-app: reason, distance vs the fence, fix
age/provider/accuracy, curfew state, and every hidden app with the rule that
hid it. Coordinates are never recorded -- a distance is enough to debug a
geofence, and this is a home address.
Also fixed along the way:
- Hysteresis keyed off `isEnforcing`, which is true under AWAY too because
YouTube stays hidden, so the threshold was permanently radius+hysteresis.
It now keys off whether the previous pass was inside the fence.
- The scheduler's curfew-boundary alarms were documented but never scheduled;
both callers invoked `scheduleNext()` bare, so 05:00 could land 15 min late.
- Installing over the app cancelled its pending alarms, so `adb install -r`
silently stopped enforcement until someone opened the app. MY_PACKAGE_REPLACED
now re-arms it, verified on device without launching the app.
- A wrong-typed log record threw instead of being skipped, and the exception
escaped far enough to leave the page stuck busy -- which disables the
release-device-owner button, the one control that must work when everything
else has gone wrong.
- `lib/enforcement.dart` was a second decision layer with no always-blocked
concept, cited by KDoc as pinned by a `PolicyParityTest` that never existed.
It would have made the new screen report YouTube visible while it is hidden.
Deleted; the UI renders the Kotlin record rather than re-deciding.
- Anchoring home accepted a stale or unknown-precision fix. A wrong home
offsets the fence everywhere and forever, which is what produced a 766 m
reading while standing at home.
Policy: Play Store is allowed by day (not during curfew) so infakt can be
installed and updated; the sweep is default-deny for third-party packages, so
anything installed from Play is hidden on the next at-home pass. Tachiyomi's
per-source extension apks are covered by a new prefix allowlist rather than an
exact list that goes stale whenever an extension is installed.
`export.py` stopped subtracting the allowlist from `blockable_system_packages`.
Sweepable is not hideable: that list decides which system packages are
eligible for a decision, and `isAllowed` is what protects them. Removing an
allowed system package from the sweep freezes it in its last state -- it would
have stranded Play hidden permanently the moment it was allowlisted.
Verified on the Pixel 6a: FINE granted POLICY_FIXED, `applied AT_HOME` with a
0 m distance from a +/-11 m GPS fix, YouTube/Chrome/Firefox absent from
`pm list packages -e`, Play Store, infakt, RunnerUp and all five Tachiyomi
packages present.

billsplit was a standalone Flutter app in ~/Downloads with one commit and no
git remote — that directory was the only copy of its history.
Three things the move needed beyond copying the tree:
- The root .gitignore silently swallowed 32 of its files (*.png, *.ico,
*.manifest). Ignored files do not error on `git add`, they just vanish, so
this would have committed an app that cannot build. Added a trailing block
of ! overrides plus .binary-allowlist (which did not exist yet) — the
documented in-repo exception for binaries a build genuinely needs. The
../testsAndMisc_binaries/ symlink scheme does not apply: those directories
are gone, and a symlinked PNG breaks a fresh clone.
- billsplit/.github/workflows/ci.yaml was inert once nested; GitHub only reads
workflows at the repository root. Relocated with a working-directory and a
billsplit/** path filter.
- The app's coverage gate moved to python_pkg/billsplit_coverage/ so every
Python file stays under python_pkg/, and gained a test suite at 100% branch
coverage as that location requires. billsplit/ now holds only Dart.
Also replaces the stock Flutter icon with a family icon from the shared
generator. The glyph is a filled silhouette because the family's 72px stroke
cannot carry a fine torn edge, and the split is an evenodd-cut perforation so
the holes stay transparent on the foreground and monochrome layers.

Moves the standalone React 19 + Vite 8 + TypeScript 6 game from
~/Downloads/reverse/reverse-survivors into reverse_survivors/, so it is
version-controlled, indexed, and covered by CI instead of sitting untracked
outside any repository.
- Relocates the project's nested .github/workflows/ci.yml to the repository
root as .github/workflows/reverse-survivors-ci.yml. GitHub only reads
workflows from the root, so the nested copy would have been inert — same
treatment billsplit received. The workflow is path-scoped to
reverse_survivors/** and runs npm ci / check / build on Node 22.
- Sets cache-dependency-path on actions/setup-node, since
defaults.run.working-directory applies only to run: steps and not to
actions; without it the npm cache looks for a lockfile at the root.
- Keeps npm and the existing package-lock.json. TypeScript stays pinned at
6.0.3 deliberately: typescript-eslint 8.65 caps its peer range at <6.1.0
and TS 7 drops the JS compiler API that typed linting needs.
- Adds a reverse_survivors/ row to the Repository Layout table in README.md
and CLAUDE.md.
Verified in place: npm ci, npm run check (95 tests, 100% statements /
branches / functions / lines), npm run build, and a dev-server smoke check
serving /src/main.tsx.

- Move pyproject.toml, .pre-commit-config.yaml, requirements.txt, run.sh,
lint_python.sh, .fvmrc into meta/ with root symlinks preserving tool
auto-discovery.
- Combine requirements.txt + requirements-dev.txt into meta/requirements.txt
(single sorted source of truth).
- Remove setup.sh, .binary-allowlist, C/ (no native code remains),
python_pkg/{split,pdfCentered,geo_data}, scripts/check_c_cpp_build_files.sh.
- Drop clang-format/cppcheck/flawfinder/check-c-cpp-build-files hooks and
archived path excludes from pre-commit config.
- Add .secret-patterns to .gitignore and untrack it (sensitive content;
full history purge is a follow-up step).
