A push took ~13s. prettier is a pre-push hook precisely because Node's
startup dominates its runtime, and pre-commit chunks a large file list into
several invocations -- a 106-file push paid ten cold Node starts. ci-mirror,
the hook that looks expensive, was already 0.02s once its green-tree cache
hit.
A file whose content, prettier version and prettier config are all unchanged
since its last clean check cannot have become unformatted, so the verdict is
now cached and the file never reaches Node. Only clean verdicts are recorded,
so a formatting regression is always re-checked; the key includes
`prettier --version` and every config file, so an upgrade or a config edit
invalidates the cache wholesale. The systemd-run memory cap is unchanged.
Measured on the same push range: 13.0s -> 3.3s total, of which ~0.6s is
hooks and the rest is git's own network negotiation. On a 40-file list the
runner itself goes 0.652s -> 0.057s, starting no prettier process at all.
endurain/README.md and copilot-instructions.md are reflowed: the ~
reorganisation lengthened paths inside them, which changed prettier's
markdown table alignment.

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.
