This read-create value reports the current progress state of a replication partner test: unknown, in progress, complete, error, or restarted. An admin polls this after starting a test via the test-action object to know when results, such as the IP and authentication status, are ready to read, or whether the test failed outright. For example, this value reading error(3) tells the admin the test itself failed to run to completion, distinct from the IP or auth sub-tests simply failing their checks.
