That is what it sounds like to me, as well. Sounds like your work was performed in a workmanlike manner, to industry standards. If it comes down to it, it may make sense to have an outside third party such as a Professional Engineer help mediate the dispute. At least real PEs have to take a really big test.
Personally, I have put in flat drains, round drains without socks, and round drains with socks. Whatever the builder wants. I usually have a buffer between me and any architects. The waterproofing has been handled by others when I get there, so that's not something I've had to worry with, but I've seen it done while I was onsite, working on another part of the house.
