I'm trying to pick out doorknobs and locks for the house and it turns out I have a lot of feelings about how doors should work

Features I want in door hardware: * always unlocked from the inside * always locked from the outside * single keyhole on the outside * momentary unlock with a key * 12V DC momentarily unlock * operates as normal when electronics are down I'll wire it to the smarthome separately

Did you find any that fit the bill?

There are tons of commercial locksets designed to integrate with access control systems that do this exact thing. You want one that is "energize to unlock" (fail safe, not fail open). If you need the model number of the one we are using, let me know.
