Ok so according to this

If something is not specifically added to your spell list by text then while it is added to your spells known you can't cast it with your class spell slots?
So where does it say that a Bloodline spell or a Mystery spell is added to your spell list and not just your spells known? I know most spells of those two are taken from their own spell lists anyway but I seem to recall a few of them are spells from other spell lists now and then. Would those spells be dead in your spells known? Since you can't cast spells not added to your spell list?
I can't seem to find the line saying they are added to your spell list in either classes's text. Am I just blind today or what?
I think the bit that you're missing from the FAQ is this.
unless they are added by a class feature of that same class.
This is to prevent a sorcerer from grabbing a magic item (like a page of spell knowledge) in order to cast a spell that isn't on their class list. They technically "know" the spell thanks to the magic item. Since bloodline spells and Mystery spells are added via a class feature, they are automatically also considered to have been added to your class list of spells.
Futhermore, it straight up tells you in the next sentence:
For example, sorcerers add their bloodline spells to their sorcerer spell list and oracles add their mystery spells to their oracle spell list.
