The most recent update (April 16th, 2015) to Streetpass added two new games, the Game Vault, and other upgrades. However, I don't recall anything in the Nintendo Direct video nor in any articles about the gold stars I now see on some of my games. In the picture, you can see that Find Mii I & II, Mii Force, and Flower Town all have gold stars next to them.
I so far haven't been able to find anything online about them. At first I thought it might be for finishing a game but I haven't finished Flower Town by far. I have finished the main campaigns of the other two games, but Mii Force isn't perfected.
What do the the gold medals on these games mean?

This community wiki answer will try to list circumstances in which people have or have not earned medals in an attempt to codify what's necessary for them.
For most of the sub-games, it is known that collecting all the related achivements is not necessary.
Puzzle Swap is simple: If you have all the panels completed, you get the medal.
