Subject: test(plugin): compare a real-plugin install against upstream Composer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Run upstream Composer and Shirabe over pristine copies of a fixture
project at the same path and require composer.lock, the whole vendor tree
(including the plugin-generated GeneratedConfig.php), the plugin's IO
lines and the exit code to match byte for byte.

The plugin under test (phpstan/extension-installer 1.4.3) is downloaded by
fixtures/e2e/fetch — pinned to an upstream commit and hash-verified — into
a git-ignored directory rather than committed; the test skips while it is
absent, like the other real-PHP prerequisites. Its dependencies are
minimal stand-ins resolved from local repositories, so test runs stay
offline. A zip dist would exercise the known lossy-string byte-precision
debt in RemoteFilesystem, so the fixture serves the plugin through a path
dist until that is resolved.
