In Iran's defense, there was credible OSINT[0] warning of the B-2s taking off 12+ hours in advance of the strike. Iran knows what a GBU-57 is, the writing was pretty clearly on the wall that a strike was imminent.
It's possible (though not guaranteed) that they simply relocated the enriched uranium before the attack.
That one was counterintelligence deliberately placed in OSINT to confuse Iran. The B-2's that flew west over CONUS in daylight, in plain view, were decoys on a wrong timing.
