ASAP input needed re: Hardie panel and rainscreens

Hi everyone. I can not believe I need to ask this question. We are supposed to begin siding tomorrow or Tuesday. We had our architects go back and redraw details so that our siding would have an air gap between it and the sheathing. I JUST found out, due to an offhand comment by our GC, that the architects ONLY drew the air gap for the areas with cedar siding and not for the areas with Hardie Panel!!
I'm beside myself. My understanding is that the salts in Hardie Panel are not good for the Tyvek housewrap. Plus I wanted the air gap for the health of the sheathing, not just the siding.

Do I need to scramble to fix this? Would you find a Hardie panel/Tyvek/OSB sandwich acceptable?
