I don't know about hardware redundancy, but yes for at least "easily verifiable limiters".

What is "hardware" anyway? Does a microcontroller-based integrator or debouncer count? Depending on how you define that, it can become a serious roadblocker. But anyway, I guess that point is moot for a door handle, you can fix it with stuff that is unambiguously hardware.

Hmm, good question. In this context, I guess "continues to work after the EMP"?

		So, antennas and grid power are forbidden, microprocessors and batteries are permitted? Do you expect a mechanical wave to come with the EMP or it originates in space?
