LookupAllRecords now returns each nameserver's response, so the watcher saves its status: ok when it answered, NXDOMAIN and no records included, and error with the reason when it timed out, answered SERVFAIL or REFUSED, or could not be reached. A nameserver that starts failing sends NS Failure and one that answers again sends NS Recovery. A failing nameserver is left out of the record change and inconsistency comparisons. The resolver used to report REFUSED and network errors as an answer with no records; they are now errors. A lookup cut short by its context now returns an error instead of a failure of the nameserver it was querying. Model: opus-5-5
