Give a detected REAC device its recognition key and address.
The key is BUILT FROM the MAC and is not the MAC: the console compares keys whole, and a bare
MAC would collide with another transport's key the day a serial reads like one. A device with
no MAC stays unkeyed — absence is a fact, and a fabricated key would hand a stranger another
box's patch.
