Each face card counts as 10 only when looking for a value, for example if you want to exploit a node that has 10 you would need to play 1 or more cards that have a total value of 10. So a jack, queen, or king would work there. This also matters when upgrading your deck when you jack out, as the cards you pull are checked for their values.
However when looking for pairs you need 2 cards that have matching ranks. So for example a queen and a king are not a pair because they are not the same rank. Two queens are a pair, two kings are a pair, and two kings and two queens would be two pair, or in the parlance of this game "double pairing".
Full shutdown, or a full house, requires 3 of one rank and 2 of another different rank. So 3 queens and 2 kings would count as a full house.
You can only play one program at a time, so a straight killotine would not also count as a flush cache.
Corpo keys is a royal flush, which means 10, Jack, Queen, King, and Ace all of the same suit.
