I don't think there's anything more I can add, so I've started double-checking the connections and passive component values to make sure everything's right. It's good that I did, too; there were a few misplaced connections, and I'd especially screwed things up around the MAX4468. While I'm at it, I'm also making one last optimization run around the positions of the chips.

I still need to check everything around the FV-1 and (especially) the MAX11312; once that's done I can generate the ground plating and have this ready for prototyping next month.
