What missions have vault doors which require a vault access card?

Intro

In Invisible Inc, there are Vault Access Cards that can be used to open vault doors in financial missions, where you basically rob a bank.

However, I'm currently doing a cyberlab mission, where I get to install free augments or augment sockets on my agents. I always thought that there were always only 2 augment stations in these missions, but this time I noticed that there was a vault door(!), and after peaking behind the vault door, I noticed that there were an additional 2 augment stations!

Here is a screenshot. Note that the 4th augment station is hidden behind the tooltip.

Question

Do cyberlab missions always have this vault door, protecting an extra 2 augment stations? Or do the extra stations only spawn sometimes?

Finally, do other non-financial missions also sometimes have these vault doors which require a vault access card?
