I'm referring specifically to the root package. https://getcomposer.org/doc/03-cli.md#create-project https://getcomposer.org/doc/03-cli.md#create-project Composer can install a project initially using "composer create-project", but that's a one-time setup. After that, the root package becomes just a static local project, not something Composer tracks, updates, or upgrades as a package. https://valvoid.com/registry/packages/1/fusion-php-package-manager/docs/interaction/terminal#build-command https://valvoid.com/registry/packages/1/fusion-php-package-m... Fusion handles everything as a modular package, including the root project. If the root package's metadata file includes the root package itself as a recursive dependency, "fusion build" can update and upgrade it just like any other package. Fusion builds the entire existing project, not just its dependencies.
