The unit suites had to install their toolchain on every run. The image now carries the interpreters, so the make prerequisite finds them present. The Composer vendor tree deliberately stays out of the image build: the package cache is reached through the compose extra_hosts mapping, which only exists for a running container, so a build-time composer install would bypass the cache and talk to packagist directly. Fetching it from the test target keeps it on the cached path.
