It seems likely, to me anyway, that the CPU doesn't have any effective way of verifing what is running on the ME. So reversed firmware could just lie to the CPU

It seems likely, to me anyway, that the CPU doesn't have any effective way of verifing what is running on the ME. So reversed firmware could just lie to the CPU and tell it that its firmware is signed when it isn't. A similar approch is use the microg project to replace proprietary google play services by spoofing google's signature.
