A try names several repositories, each the exact commit asked. A whole try (not narrowed to a level or tests) runs the group check's own path: the manifest validator, the module graph and the composition on every placed node, reading the indexer's candidate of the try's group. A try with no such candidate is an error that says so, never a pass. A try's candidate is no check: the checker leaves it alone and owes the forge nothing.
