And never mind the multiple posted links that say the Iranians were cheating/hiding.

If you won’t ever acknowledge what others post, there is no exchange of ideas.

But you didn't post links that said they were cheating/hiding. You posted links that said they were cheating before the JCPOA was entered into. That they had increased their uranium holdings before the JCPOA went into effect, and that they were trying to avoid the import controls that existed in 2012 and 2013 before the JCPOA. The only link you provided that related to the term of the JCPOA itself was their effort to acquire carbon fibres that were permitted under the JCPOA, but for which they were required to notify - a relatively minor breach, and one that would have been easily detectable if they had actually acquired the fibers and tried to use them, since the facilities were monitored.

IOW, there's no evidence that the Iranians ever cheated in the primary objective of the JCPOA - to keep Iran's available uranium stores limited to only a few hundred kilos and that it not be enriched to weapons level.

Like you said, there's no exchange of ideas if you don't acknowledge what others post. All of the available information is that Iran maintained their uranium at levels below the thresholds in the JCPOA, and only after the JCPOA was abrogated by Trump did they spring to heavy enrichment of large quantities. The JCPOA worked while it was in effect.
