Yeah this Story quickly became a Nightmare... I'll see myself out
Not sure how this specific bait and switch went down, looks like they slowly cheapened the design throughout the approval process. The file planner should have been all over that.
I can say that once you get site plan approval, I don't think city planning staff even follow up with building code staff to make sure you build exactly what was approved. The city is a bit dysfunctional in that way, and also understaffed. I also don't know what the penalty would be for a post-approval bait and switch. I'm sure in places like NYC they'd slap you with a hefty penalty or make you tear it down. Here? Probably a slap on the wrist if anything.
