The State of Arizona did the audit. They hired someone for the particulars, and to do the forensic analysis they are unequipped to do.
The Republican caucus contracted for the audit. It was paid for by private donations. To say that the State of Arizona did the audit is a stretch.
IMHO
By the general lack of consensuse this thread points out that decertification is not a clear remedy. Likewise, the lack of more than a one vote majority in the AZ Senate and the AZ House mean that election reform(s) are going to be haphazard at best. But election reform is the most practical thing that can be mounted with a very vocal and mad population pushing all involved.
