If a device is slaved to a cyber deck/comlink the master's ratings are used so effectively it acts as a buff in a sense, or as a supportive relationship between the two devices with the master also taking the risk of being found and marked when the slave is under attack.
The first issue I see in your understanding of this relationship is that you are looking at it in a very "gamey" fashion.
Do I understand this correctly that effectively a master is not really a master anymore, as nowhere in the book is it stated that the master has any control over it's slaves. If the master doesn't have a mark on it's slave it can't even issue commands to it's slave, but still it acts as it's master, is that correct or am I overlooking something (Do consider I am only talking about PANs, WANs are in my opinion much more well explained).
This is where things get kind of funky. The way I see it, the master should have "ownership" marks on the slave. But the way the book says things work, there's nothing giving a master control over a slaved device just by creating the PAN/WAN. Though it stands to reason that a slaved device would offer marks to the master device.
And then there is the ownership. If I am an owner I have full control over something. Now here is what I am wondering, and some examples in the book seem to support this: If I have marks on an owner I have access to everything the owner owns without separately marking all the devices the owner owns but I am not sure if I read this correctly.
Ownership is a funky subject as well. I anticipate that we'll get a LOT more info on marks in
Data Trails. If I had to guess, I'd say that we'll see a special type of mark for owners, which gives unique access. We might also see other types of marks, but honestly this is all conjecture.
Operating just off the normal rules (which you should do unless you're prepared to go down the house rules rabbit hole), if you have marks on the owner, you only have marks on the owner. Master/slave relationship rules apply here. If you get a mark on a slave, you get a mark on the master. Also, remember that a device that has created a persona (like a commlink) is no longer a part of a PAN. The persona is still the owner, but is no longer part of the PAN.
If all this seems confusing, just remember that the Matrix is basically just like magic. The technology used for the Matrix is complete fantasy and has almost no correlation with real-world technology. Any attempts to use real-world technology knowledge to understand the Matrix will result in you driving yourself insane.
