Is there still a hard deadline for launch of Artemis I? I though that the SRBs had a shelf life after which they couldn't be used. Have they been re-certified?

How many times have the tanks been filled, either partially or completely? Isn't there a limit (~22 fillings, I think) on the number of times that can be safely done? How close is this vehicle to End-of-Life from various components aging out or hitting wear limits?

Welcom to SDC, JLB39401!!
As best we can tell there was the Green Test, then three fillings in March/April and then the three launch attempts. Total about 7 out of 22 allowable.

I seem to remember some issues coming up during the Green Run; they had one run where they could not do a full-duration firing, & I think they repeated it. Not sure if they did tank filling & emptying without firing as part of the test series, but I would be a little surprised if they didn't.
