This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- assert assigning a non-module object in an explicit namespace file immediately raises Zeitwerk::Error from const_added during autoload, escaping rescue NameError and rescue TypeError
- assert push_dir rejects Symbol and String namespace arguments with Zeitwerk::Error rather than TypeError or ArgumentError
- assert push_dir rejects anonymous modules with Zeitwerk::Error stating root namespaces cannot be anonymous
- assert calling reload without enabling reloading raises Zeitwerk::ReloadingDisabledError while calling enable_reloading after setup raises base Zeitwerk::Error
- assert calling eager_load before setup raises Zeitwerk::SetupRequired rather than RuntimeError or ArgumentError
- assert load_file normalizes missing files, non-Ruby files, ignored files, hidden files, and unmanaged files to Zeitwerk::Error instead of LoadError or Errno::ENOENT
- assert conflicting explicit namespace file and nsfile definitions raise Zeitwerk::ConflictingNamespaceDefinitionError identifying both file paths
