So they made a first real test with Artemis I, and it was deemed unsafe because of the heat shield. So they modified the heat shield and didn't bother making a real test with it. "Move fast and break things", I guess?

Sure, they tested it on the ground. But that's what they did for Artemis I, and we know how successful that was.

According to the article [0] that's been making the rounds, NASA didn't make any changes to Artemis 2's heat shield after getting data from 1's re-entry. NASA did change the trajectory for 2, and they made the compound "less permeable" but that change was made before 1 flew.
