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.

"""Run pytest for all python_pkg subpackages whenever any Python file changes.
|
|
|
|
Used as a pre-commit hook entry point. Receives staged file paths as arguments.
|
|
If any Python file changed, discovers every subpackage under ``python_pkg/``
|
|
that has a ``tests/`` directory and runs them all in a single parallelised
|
|
invocation with whole-repo coverage measured against ``python_pkg``.
|
|
|
|
Running all packages together (rather than just the touched ones) ensures that
|
|
100% branch coverage is maintained across the entire codebase on every commit,
|
|
not just the files that happened to change.
|
|
|
|
Standalone script suites outside ``python_pkg/`` (currently
|
|
``linux_configuration/tests``) are also run so their behaviour is gated, but
|
|
they are not coverage-measured (coverage stays scoped to ``python_pkg``).
