Regret's in atmosphere jump.... Heresy?

Rereading First Strike and when Cortana is able to figure out how to make a jump to Slipspace in atmosphere the Covenant AI onboard calls it “Heresy”. This semi suggests that the Covenant had not done such a maneuver so far and raises questions about Regret’s Carrier in Halo 2 making an in atmosphere Slipspace jump inside Mombasa next to the space elevator.

Did Regret commit Heresy in this maneuver? How did they Covenant figure out how to do this if Cortana is the only one to have figured out how to do it?

The Covenant AI is more upset about the fact that Cortana is utilizing Covenant technology and figuring out a more efficient way to use the said technology through application of UNSC science rather than the act of jumping in atmosphere itself. The Covenant most likely knew how to and performed in-atmosphere jumps before, but did so in a less efficient way, so while that was NOT heresy, Cortana figuring out a better way to do it and thus spitting in the face of Covenant science and theology (not to mention being a filthy foreign, hostile AI infiltrating a Covenant ship’s system).

That’s what made the Covenant AI mad, not the jump itself.

Potentially but in the book Cortana is the one thinking it is the Ai that considers the in atmosphere jump itself heresy in addition to the fact that if the Covenant knows how to jump in atmosphere, they’d also be able to jump from Slipspace to in atmosphere and thus completely bypass the orbital defense grid there by making them useless. It’s at that point that Cortana believes humanity might be able to out think the Covenant since till that point they had been imitative not innovative.

Cortana was working with what she had available to her. From her perspective, it may seem that the AI was calling an in-atmosphere jump heresy. But in reality, it would seem that the Covenant AI was viewing her interference as a whole to be the true heresy. You are correct that the Covenant is more imitative than innovative. That only furthers the legitimacy of the assumption that the Covenant AI finds humanity’s interference in their technology as heretical rather than the technology itself.
