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.

- 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).
Layer 1: Pre-commit hook (scripts/check_no_binaries.sh) blocks 60+
binary/image extensions with .binary-allowlist for build-essential exceptions.
Layer 2: Comprehensive .gitignore binary patterns with ! overrides
for allowlisted files (app icons).
Layer 3: Agent exclusions - .copilotignore, files.exclude, and
search.exclude all mirror the same patterns to prevent Copilot
from hitting the 20-image URL limit.
