Well, they found 83.7% fuel particule does not necessarily mean they are at 83.7% enrichment cycle, it just mean they have material that has 83.7% U235 in it, I mean if you pick a spot in the centre of the centrifuge, it ALWAYS have the highest amount of the % of the cake because that's where the U235 start mixing instead of separating (Again the concentration of U235 will be the biggest in the middle of the entire cake), it means that it could be a by-product of fission, it could also mean they reach the 60% +. It only mean that it is unlikely it was in low percentage,Thanks for the recap of information.
As far as IAEA is concerned. They detected at 83.7% , and that too in 2023. Probably past three first stage.
However 2nd stage is still in question.
"In 2023, the IAEA said uranium particles enriched to 83.7% purity – close to bomb-grade levels – were found at an Iranian nuclear facility. Its stockpile of uranium enriched up to 60% had also grown to 128.3 kilograms, the highest level then documented."
You need to examine the cake instead of the particle left in the centrifuge to know how far the enrichment process has gone. I remember they found 45 or something % 10 years ago on a 22% fuel they were showing to the IAEA
