Sorry, but what does it mean to “bed in” CCB?

No need to bed in. There are 3 different things that people can refer to when saying "bed-in" - 1) form a transfer layer of brake pad material on rotors - this does not apply to street driving at all, because the pads do not get hot enough, so even if you do the bed in, the trandfer layer will rub off very quickly during normal street driving. For track driving, it's also not necessary because the transfer layer forms by itself as long as you do not go into ABS on the first 2-3 laps of the day (which one should not do anyway) and then goes away after less than 100 miles of street driving. 2) mating the surfaces of pad and rotor to match each other - this still happens, and braking is not as great until it does happen, but because the PCCB rotor is perfectly flat with no grooves or other deviations, it takes just a very short normal drive; 3) heating up pads to get them to fully cure and to release all gasses - not relevant to modern pads used by Porsche because it's done during manufacturing. So it's one less thing to worry about.
