## [Unreleased]

## [0.2.2] - 2026-09-15

### Changed

- `make install` copies `bin/git-locks` into `$(PREFIX)/bin` instead of symlinking it. The symlink made the development checkout live for every consumer on the machine: while the v0.2.1 refactor was in progress on a branch, a downstream project's pre-commit hook ran the half-fixed script and its lock step failed once. An installed binary is now a snapshot of the checkout it was installed from; upgrade by re-running `make install`.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Replace the installed executable atomically. README.md documents re-running make install as the upgrade workflow, and git locks resolves the installed file from PATH. In the repository's Ubuntu environment, GNU install unlinks the existing destination before it opens the replacement. A concurrent invocation can therefore see $(PREFIX)/bin/git-locks missing or partially written.

Create the temporary file in $(PREFIX)/bin, install it with mode 0755, then rename it over the destination. Remove the temporary file if installation fails. A same-directory rename preserves the copy and permission contract while avoiding the replacement window.

In `@Makefile` at line 16, Update the Makefile install target to replace
$(PREFIX)/bin/git-locks atomically: create a temporary file in the destination
directory, install bin/git-locks there with mode 0755, rename it over the
destination only after installation succeeds, and clean up the temporary file if
installation fails.

## Install

```sh
make install # symlinks bin/git-locks into ~/.local/bin
make install # copies bin/git-locks into ~/.local/bin (a snapshot of this checkout, on purpose)
git locks list # git dispatches `git locks` to git-locks on PATH
```

`make install` copies rather than symlinks. A symlink into a development checkout makes every uncommitted edit live for every consumer on the machine at once; on 2026-09-15 that turned a half-finished refactor into a transient lock failure in another project's pre-commit hook. Install from a tagged checkout and re-run `make install` when you mean to upgrade.
