Follow-On Verification

@dianakhuang @ormsbee are free to start reviewing at their convenience—though, I will likely continue doing quite a bit of cleanup throughout the rest of today / probably some over the weekend, so you can also wait until next week if you prefer.

A few TODOs are noted in the code with some general design-ish questions that I'd appreciate input on (as well as some TODOs that other devs may be able to knock out quickly if they have some spare time).
