LoadProject and Generate (the api.ProjectLoader operations) need two things from the engine: the Docker API, to read the containers a project is generated from, and the Docker CLI, which resolves remote Compose files. They now live in internal/projectloader, along with the unsupported attributes detection only the loader uses, behind a Backend interface that composeService implements in a new file of pkg/compose, like internal/inspect. The tests move with the code; their assertions are unchanged, only the way the service is built differs. The canonical container name, which both this package and internal/inspect need, moves to a tiny internal/naming package instead of being copied a third time. pkg/compose keeps its own copy until the shared kernel is extracted.
